Drilling rig forehead 50. Machines for auger drilling. Screw pumps for wells

Installation of LBU-50

The LBU-50 drilling rig is designed for the construction of hydrogeological wells with a diameter of 200 mm to a depth of up to 50 m and pits with a diameter of 1,050 mm and a depth of 15 m.

The main method of drilling wells is auger in combination with percussion-rope.

The pits are drilled with a special bucket drill, lowered to the bottom along a smooth drill string. They lift it to the surface on a rope using the installation's winch.

All equipment of the LBU-50 installation is mounted on the chassis of a ZIL-131 all-terrain vehicle.

The main components of the LBU-50 self-propelled drilling rig are shown in Figure 1.

When transporting the unit, the mast is in a horizontal position. The supply hydraulic cylinders in the upper part are connected to a movable crossbeam, and in the lower part - to the lower plate of the mast using rods. The mast traverse and hydraulic cylinders provide an increase in the height of the mast by the stroke of the rotator feed hydraulic cylinders.

Figure 110 shows the kinematic diagram of the LBU -50 installation. The installation is driven by the vehicle's running engine, which is monitored by the speedometer. The rotation is transmitted through the power take-off, gearbox and bevel gear to the rotator and winch with an impact mechanism. The winch and rotator can work separately or together. From the gearbox, rotation is transmitted to the oil pumps of the installation’s hydraulic system.

From the bevel gearbox through the cardan shaft, rotation is transmitted to an angular gearbox connected through a gear coupling, a vertical shaft and a safety clutch with an upper gearbox mounted on the top plate of the mast. The gear coupling of the vertical shaft in the working position is put on the half-coupling of the angular gearbox, and before lowering the mast into the transport position, it moves up and is fixed with a latch. The coupling half is turned off by a hydraulic mechanism, the control of which is interlocked with the handle for raising and lowering the mast. A vertical shaft passes through the passage hole of the upper gearbox, the upper end of which is fixed in the traverse, and the lower end in the drive gear of the rotator. The rotator is pivotally connected to the carriage, which is moved by hydraulic feed cylinders up and down along guides, which are used as pipes of the front legs of the mast. Augers are connected to the rotator spindle through removable adapter cartridges when drilling wells or drill pipes when drilling pits. The LBU-50 installation has a set of augers with a diameter of 180 mm.

To construct pits, a special bucket drill with a diameter of 740 mm is used. At the bottom of the drill there are windows equipped with knives and rubber valves, installed when constructing pits in water-saturated rocks. At the top of the drill there are folding expander knives that drill a hole with a diameter of up to 1050 mm.

During lowering and lifting operations, the expander knives rotate on hinges and enter the drill body, and when lowering to the face, under the action of a special spring device, they are extended into the working position. This design of the drill allows you to go through a hole while simultaneously fastening it.

"LBU-50"

LBU-50 is a modern multi-purpose drilling rig of domestic production. Its design was developed in the Soviet Union and tested over many years of operation by many drilling organizations in Russia and neighboring countries. It was created for long-term operation in field conditions with extremely limited maintenance capabilities. Therefore, the designers sought to make the design of the installation as simple and reliable as possible, thanks to which the LBU-50 has become an indispensable tool in geological expeditions. The installation combines balanced technical characteristics, practicality, endurance and high productivity, which is very important for the work of drilling companies.

The LBU-50 drilling rig is distinguished by its versatility, reliability and unpretentiousness. It is used for drilling water wells, construction and technical wells, and conducting engineering and geological surveys. This installation is capable of working on any type of soil and performing excavation of various depths and diameters, thanks to the variety of drilling tools that can be used on its basis:

• auger drills and drill bits (for drilling up to 60 m),
• augers (for drilling up to 25 m),
• down-the-hole hammers
• other drilling tools for the construction of special-purpose wells.

Due to the fact that the installation is equipped with a compressor or pump, it is possible to drill using the blowing method (up to 100 m) or flushing (up to 200 m). The drilling tool is selected depending on the task and allows you to drill wells of any complexity.

The simplicity of the design allows the installation to be repaired even in the field, if the necessary spare parts are available.

High off-road qualities of the drilling rig are achieved by installing it on a ZIL, KAMAZ or URAL chassis, which makes it possible to carry out geological surveys and drilling even in hard-to-reach areas. Rotation is transmitted to the drilling tool from the chassis engine through the power take-off.

Spare parts "LBU-50"

The LBU-50 drilling rig is designed for intensive, trouble-free operation. Yet, despite the high reliability of components and assemblies, all mechanical parts are subject to wear. Any components and mechanisms have a limited working life, which can be reduced due to errors by operating personnel and violation of operating rules set forth by the manufacturer. From time to time it is necessary to replace worn parts of the LBU, especially for heavily loaded mechanisms, such as:

• Transmission
• Rotator
• Winch with bevel gear

Auger drilling of wells: technology, equipment and stages of work

Drilling water wells is a responsible job that requires appropriate experience and equipment. It is necessary to take into account many nuances of the work itself and the characteristics of the soil.

Also, the correct choice of drilling technology is important. One of the simplest and, most importantly, cheapest is the screw method. It is quite popular and allows you to quickly make wells.

Operating principle of the screw method

This method is a rotational one, and is actually quite simple and accessible for independent use. One of the popular representatives is an ordinary garden hole drill. Another representative of manual auger devices is the ice ax. These devices are familiar and understandable to everyone.

The principle of auger drilling technology lies in the constant rotation of the blades and supply of the workings to the surface. Basically, augers for drilling water wells consist of:

• a central pipe or drill rod, along the entire length of which a steel strip is helically attached;
• tip, which inserts into the ground.

The tip cuts and loosens the soil. And the metal strip functions as a conveyor belt through which the soil excavated during the drilling process is supplied from the well.

The tip is most often made removable, so it can change depending on the type of soil. Typically used:

• three-blade chisel;
• bit with two blades;
• paddle drill

In some modifications, the tip is made permanent.

In general, this method is mainly used for making shallow wells. However, if necessary, the penetration length can exceed 50 meters. There is no need to lift the equipment during work. As they deepen, the augers are expanded with additional sections.

Auger drilling

Peculiarities

Auger drilling technology is used mainly on loose and loose soils. It ensures high speed of work - you can walk 100-200 meters in a day, and this is a pretty good indicator.

When drilling, there is one nuance - the choice of the pitch of the tape turns should be calculated in such a way that the slurry (exhausted soil) does not occupy more than half of the volume of the interturn space. Ideally, production should occupy about 30% of this volume.

This must be taken into account, because Due to rapid rotation, the screw and tip will heat up. The speed can be:

• with a tooling diameter of 200 mm – rotation speed is 100-150 rpm;
• with a diameter of 100 m - rotation speed up to 500 rpm.

Thus, the cooling of the auger occurs due to the movement of rock along the blades. Some modifications also provide water cooling. To do this, the auger for drilling wells is made on the basis of a hollow pipe through which cooling liquid can be supplied.

Advantages and disadvantages

Like other drilling methods, auger drilling has its own characteristic pros and cons.

Advantages of the method:

• simplicity;
• speed of work;
• you can make wells of large diameter, up to 150 cm;
• it is possible to drill deep holes;
• the excavated soil rises continuously to the surface, without the need to remove the equipment;
• no supply of flushing liquid is required, as, for example, with rotary technology;
• can be drilled in any direction, for example at an angle;
• a wide range of applications, in addition to drinking wells, the installations are used for exploration work, installation of pillars and piles, etc.

Flaws:

• not suitable for all types of soil - works best on loose and soft soils;
• You won't be able to make deep holes.

However, one of the main disadvantages is the inability to use on hard soils. In addition, if during work the auger encounters a large stone, this can stop the process. Thus, the auger method is inferior to others in terms of versatility, for example, the rope-impact method, which can be used almost anywhere.

On the other hand, the simplicity of the equipment and the speed of work make this method popular. It is especially in demand when work is carried out at shallow depths.

Tip

Equipment

Auger installations for drilling wells are divided into three types:

• manual;
• light mobile;
• heavy mobile.

They are intended for different tasks but work on the same principle.

Manual settings

The main advantage of such models is their light weight and compactness. Many models are equipped with a motor, which greatly facilitates the process of drilling holes in the ground.

Main characteristics of manual models:

• compactness;
• light weight - the maximum weight of the installation reaches 200 kg, while the average weighs up to 50-80 kg;
• used for drilling drinking wells, as well as other construction work.

Due to their compactness, these small-sized units can be used in any environment. You can also work indoors, such as a basement.

Light self-propelled units

These are more powerful units that are installed on the base of trucks. This makes their transportation easier. They can also use the car's chassis as a drilling platform.

Peculiarities:

• the weight of installations can reach 1 ton;
• ease of movement;
• high performance.

Naturally, such units outperform manual ones, but this is already industrial equipment.

Heavy installations

They are also mounted on heavy truck chassis. However, unlike light ones, they are already a drilling complex, because integrated with vehicle systems.

Peculiarities:

• control of the installation from the vehicle;
• the ability to drill wells of large diameters and depths;
• Autonomous operation - no additional equipment required.

Thus, installations for this type of drilling are quite widely represented on the construction market. And they allow you to perform different types of work, and are also aimed at all consumer groups - from homeowners to large industrial enterprises.

LBU drilling rigs

One of the most popular mobile units for auger drilling is the LBU 50 model. It is installed on the chassis of the following trucks:

These drilling units are highly powerful and reliable. They are used both for the manufacture of drinking wells and for general construction and exploration work.

LBU installation

The machine can carry out different types of work:

• auger drilling;
• shock-rope;
• with flushing;
• with purging;
• core.

Thus, it is quite versatile and can be used on various types of soils. Also, during the drilling process with forehead-type machines, casing pipes can be installed.

Main characteristics:

• belongs to the class of self-propelled units;
• maximum well diameter – 850 mm;
• maximum penetration depth – 200 m;
• drilling depth with augers – 50 m.

In the basic configuration, the unit is equipped with all the necessary elements for drilling operations.

CO-2 installation

This is another popular industrial model. Auger drilling of wells using type C 2 machines is used mainly for constructing piles. The installation is based on cranes or excavators.

Main characteristics of the model:

• the ability to expand the well base;
• maximum drilling depth – 30 meters;
• maximum diameter – 60 cm;
• type of drilling – auger.

CO-2 installation

Cost of equipment

The average price of drilling equipment can vary from several thousand rubles to millions. This is due to the fact that there are many models on the market aimed at different consumers.

For example:

• installation of LBU-50 - the average cost, depending on the base and configuration, varies from 3 to 4 million rubles;
• small-sized installations are much cheaper. For example, the UKB-12/25 model costs about 200 thousand, and PM-23 around 100 thousand;
• kits for manual drilling will cost even less - the average cost will be in the range of 20-30 thousand;
• a simple auger drill can be purchased for 2-3 thousand.

Among the equipment, the most popular and diverse range of small-sized units. Because for relatively little money the buyer receives a full-fledged drilling unit.

Features of the work

This technology has some features:

• The most effective method of auger penetration is considered to be drilling with equipment equipped with a central channel. In this case, air or a special water solution can be supplied to the cutter;
• If it is necessary to make deep wells, different drilling technologies are most often combined. For example, shock-rope is additionally used. This is due to the fact that the auger is not designed to pass through hard layers, as well as boulders;
• The walls of the hole become very compact during drilling, therefore, wells are most often characterized by low flow rates.

Thus, although the technology has some disadvantages, it has become widespread. This is primarily due to the speed and simple technology - which is indispensable when carrying out construction work. It is also common among homeowners, since it allows you to make wells without significant financial costs.

How auger well drilling is performed

Drilling a well with an auger

Auger drilling is very often used to create water wells. The process of such drilling consists of crushing and sampling the soil. An auger is used as a tool for drilling wells. The hard rock is destroyed during the work with a special cutter and then removed using an auger to the ground surface. The article discusses the issues of do-it-yourself drilling.

Types of well drilling

You can drill a water well on a personal plot or summer cottage using one of the following types:

The listed drilling technologies differ from each other in the methods of rock destruction and methods of extracting soil structures from the shaft. In each case, certain equipment is used, which affects the quality differently, which determines the final price of the work. Each method of the process can be seen in the video. This article discusses in more detail the issues of drilling wells using the auger method, and the features that an auger well pump has.

What is auger drilling

The essence of the process is to destroy the rock with a chisel, followed by its delivery to the surface using an auger screw that rotates at high frequency. This method is used in the presence of rock of low hardness and without flushing the well. Features of the process:

• When auger drilling, a high speed of work is ensured without grinding and abrasion of the rock that has already been separated from the bottom.
• The face is cleaned continuously, simultaneously with the destruction of the rock.
• When separated from the face, the rock is fed to a screw auger, which rotates at high speed. The centrifugal forces that arise press it against the walls, and a constantly moving screw belt lifts the rock upward. In this case, part of the rock is rubbed into the walls using the flange of the tape.
• With this process, the face is well cleaned of destroyed rock. This ensures high drilling speeds up to category IV rocks in terms of drillability.
• High mechanical speed is ensured when passing through weak cemented deposits of small pebbles and crushed stone. This is due to the fact that the latter are not destroyed, but are brought to the surface entirely.
• The auger conveyor does not work well in viscous clays that stick to the augers and prevent the transportation of drilled rock.
• The bit and augers are cooled due to their rapid penetration into soft rocks with constantly changing temperatures.
• Auger drilling can be done to depths from 1.5 to 80 meters.
• This process is used for drilling exploratory and engineering-geological wells, during hydrogeological studies in combination with other methods.

Advantages of auger drilling in soft rocks:

• High deepening speed.
• Rock transportation is carried out without lifting the tool, continuously.
• Drilling can be done without flushing.

Disadvantages of the process:

• Relatively shallow drilling depth.
• Rotating a heavy screw column requires more power.

The design of the auger drilling tool includes:

• Bit.
• Auger drill collar.
• Column of augers.

Well drilling tool

Advice: To increase the service life of the bit, it must be reinforced with carbide cutters. The diameter of the bit must be 15-20 mm larger than the diameter of the auger for free rotation of the auger column in the well, due to the fact that a slurry crust forms on its walls.

The most popular are two- and three-blade chisels. The body of a three-bladed bit is made of steel casting with serrated blades inclined along a helix. Carbide octagonal cutters reinforce the blades.

Machines for screw installations

The rotation of the working tool on the screw installation is carried out by special machines. Thus, auger drilling of wells using machines of the LBU 50 type is provided by a movable rotator, which eliminates the use of spindle and rotor type devices. This is necessary to provide high torque and carry out translational axial movement of the screws. To ensure high speed, machines must be powerful, highly productive and have sufficient mobility.

To do this, they are often installed on the chassis of tractors or cars, as shown in the photo.

Well drilling rig

Auger drilling of wells using CO 2 type machines is carried out with a mounted working body. The CO 2 installation is installed on an E-1252 type excavator. On it:

• Using a hinged device, a stand is attached to which a hinged working element is movably connected, including a carriage with an electric drive.
• A telescopic auger drill string with a drilling tool and a cleaner is installed on the shaft of the device.
• The column consists of two telescopic sections; auger blades are mounted on the bottom.
• The reamer or auger with a drill bit is pinned to the bottom section of the column.

The purpose of the drill bit, which has the shape of a three-blade bit that rotates, is to destroy the soil in the bottom and feed it to the drill string auger. For different soils, a set of crowns is included with the installation.

Tip: To hold the drill string when switching telescopic rods, you need to use an interception lever from two levers.

With this device you can drill to a depth of up to 70 meters, and the use of an expansion tool allows you to increase its diameter to two meters.

Screw pumps for wells

Auger pumps for wells are widely used, operating on the same principle as drilling installations - supplying water to the surface using an auger.

Screw pump for wells

A downhole auger pump, unlike others, can pump liquids containing abrasive particles and aggressive chemical elements. Work equally well in vertical and horizontal positions. They are distinguished by their reliability and simplicity of design, the price of the units is acceptable for use on any site.

Screw submersible pumps for wells have several important features:

• Convenient design. The attached instructions allow you to operate the device without any problems and, if necessary, carry out repairs.
• During repairs, the pump can be easily dismantled; all wear parts can be easily replaced with new ones.
• The design of the product is carefully worked out. There is no possibility of deposits on the suction body, and the suction pipe can be rotated 90 degrees.
• There is no vibration, which leads to increased service life.

Auger drilling of wells at a summer cottage

• Features of drilling using a blade cutter
  • Well drilling equipment
  • Well construction with screw-type pumps
• Conclusion

Do you need a water well, but don’t know what method to use to build it? You need to choose the simplest, most inexpensive and effective method, for example, drilling with LBU 50 type machines.

What is the construction of water intake wells using this equipment, what advantages are typical for such structures and with what equipment are these wells equipped? We will answer these and similar questions within the framework of this article.

Characteristics and photos of the DML drilling rig and its modifications: LP 1200 and SP

The equipment of a drilling rig depends on the conditions in which it will work, the purpose of the well, the properties of the soil and the drilling method.

Manufacturer and purpose of DML drilling rigs

Founded in 1873 in Stockholm, Atlas Copco produces equipment for the construction, drilling, and railway industries. The constant pursuit of perfection has made the equipment from the Swedish brand unsurpassedly effective.

The four main industries that Atlas Copco focuses on are:

• equipment for mines and drilling;
• mobile equipment for construction and energy generation;
• compressors;
• tools for industry.

The Atlas Copco DML series of drilling rigs is designed for rotary drilling. The depth of the wells is in the middle range.

Drilling that is carried out using these installations:

• rotary - rotational drilling, when a bit (a tool for breaking rock) deepens the depth of a cylindrical well; rotation is transmitted to it from the rotor through a column of drilling pipes;
• the rotor receives rotation from the engine;
• drilling using a down-the-hole hammer - multi-pass.

Design Features

DML units are mobile equipment; they are equipped with crawler tracks and hydraulic drive. The upper hydraulic drive is a development designed for drilling explosive-type wells up to 53.3 meters deep. When replacing the pipe, a depth of 62.5 meters can be achieved. For standard and additional pipes (9.15 and 10.7 m), additional carousels with different volumes are provided.

Small drilling

If you decide that you need an independent source of water, then order well drilling. If you do not have enough space on your plot of land, then using small-sized well drilling rigs is suitable.

Why is small-sized well drilling popular in the Moscow region?

Water layers in the Moscow region lie quite heterogeneously to the surface, so small-sized drilling of water wells is applicable in most cases. It also has many advantages:

1. This is the most inexpensive way to drill a well.
2. Small-sized drilling is successfully carried out in cramped conditions.
3. There is no need to prepare the area or access to it. The drilling rig does not take up much space.
4. Suitable for areas equipped with various structures: fences, platforms, flower beds. Only those structures that will be replaced by a well will need to be removed.
5. Low consumption of electrical resources.
6. You will need to use a small team - 2 people.
7. The work is done quickly.
8. The warranty on work and well will be 3 years. This is enough to cover the costs.
9. Drilling is suitable in most cases, with rare exceptions and complications.

Drilling wells using small-sized equipment is a convenient and quick way to provide an area with drinking water. At the same time, the water supply system will also be inexpensive. The budget proposal is to organize a summer water pump instead of a full-fledged water supply. This option is ordered for non-residential summer cottages and garden plots.

We carry out small-sized drilling throughout the Moscow region. Thanks to the professionalism of our employees, we can serve everyone during the season and you won’t have to wait in line.

How much does it cost to drill water wells using small-sized equipment?

This largely depends on individual conditions. Call us and get a comprehensive answer to this question.

The price for drilling in cramped conditions with small-sized equipment starts from 2,000 rubles, per meter of drilling using 133 metal casing pipes. When using 133 metal + 117 food grade plastic, the drilling price will be from 2,400 rubles per meter.

*Check the cost of small-sized drilling with the company’s specialists.

Consulting a specialist will help you get a comprehensive answer. The cost of such a well is cheaper than our clients expect. Access to a water source will appear within a few days.

The cost includes the materials spent on the well and its manufacture. The well lasts longer if higher quality materials are initially used. Making a pipeline from more expensive materials is cheaper than making a new well.

Characteristics of a small-sized MGBU installation

Our small-sized drilling equipment is a serious competitor to the common URB 2a2a drilling rig on the ZIL-131, KAMAZ, URAL chassis.

The small-sized installation is capable of extracting water from various layers and has a maximum drilling depth of up to 160 meters! Our equipment is tracked, and this contributes to careful treatment of the land, and also has increased cross-country ability. This drilling technique allows you to drill wells even indoors, but it is necessary to provide access and have a room height of more than five meters.

• Mast: height of the mast when raised is 5 m.
• Chassis: crawler
• Drilling depth: up to 160 m.
• Dimensions (LxWxH): 5200 x 1500 x 2100 (mm)
• Weight: 3600 kg.

Our crawler-mounted drilling equipment opens up new opportunities for drilling wells in hard-to-reach places on your site, and has increased maneuverability. We can drill where others cannot!

Drilling wells with a small-sized installation

Both large-sized URB-2A-2 drilling rigs and mobile rigs, which are lightweight and compact in size, can drill individual wells in the private sector or on a summer cottage. Modern small-sized drilling rigs are capable of performing almost any drilling task, except for drilling deep artesian wells.

Mini installations do not harm the territory of the site where drilling is being carried out, and they can be drilled anywhere and at any time of the year in the Moscow region, they are very mobile - this is their main advantage.

Many people want to drill in a convenient place without damaging the soil and are willing to pay for it: the cost of a meter of drilling with small-sized installations ranges from 2,500 to 4,000 rubles.

Capabilities of large-sized drilling rigs

The maximum drilling depth for large rigs is 300 meters. The ability to use one of three variants of the rotary drilling method with flushing, with purging, with the help of an auger allows users of the installation to open the aquifer in any soil.

The high power of the installation makes it possible to quickly drill a well for the Moscow region. All these advantages determine the popularity of the URB-2A-2 among drillers. But situations often arise that do not allow using these installations to perform work.

In such cases, wells are drilled using small-sized equipment.

Conditions for placing large-sized drilling equipment

To drill a well on a site using URB-2A-2, it must meet a number of requirements:

• gate width – at least 3 meters;
• the height of the arch, power line and tree branches above the entry point and above the path along which the installation will move is at least 4 meters;
• availability of free space for a working area with an area of ​​36 to 60 m2;
• the height above the working platform to branches, electrical wires and roof slopes is at least 8.5 meters (the tower rises to this height when drilling).

The area where drilling operations are to be carried out does not always meet these requirements. In this case, it is impossible to place large-sized drilling equipment on it.

There is a way out - drilling wells with mini-rigs!

Drilling with a small-sized rig: advantages and disadvantages

Advantages of mobile technology:

• large drilling depth up to 130–150 meters;
• will pass through a gate less than 3 meters wide;
• can be placed anywhere on the site;
• requires a small area for installation;
• does not damage the landscape.
