Hydro drilling of water wells by their own hands: technology, equipment

The system of autonomous water supply quite often acts as the only way to arrange water supply for cottages and country houses. In the role of the source, a well is selected, which is equipped on the site. Owners, as a rule, reveal the desire to implement the process of arrangement with minimal losses for the territory, this is especially true when the exterior is refined. It is also important to save money. Of course, special equipment and additional tools will be needed, but it is important to decide whether you will lead the work yourself or entrust the matter to specialists.

Description of the technology

An excellent solution in this case is the hydro-drilling of wells for water, with their own hands, such work can be fully implemented. The method is based on the technology of destruction of soil rocks with the help of drilling tools and fluids. The load can be provided with drilling equipment and the weight of the rod, by means of which a drilling fluid is injected into the borehole under pressure, it is also called drilling mud. It is a slurry consisting of water and clay.

Near the drilling site, it is necessary to dig out pit pits, the size of which is 1x1 mm. They are filled with a drilling mud, connected with each other by trays. Drilling solution is supplied to the face. To do this, the outlet hose is immersed in the pit, but beforehand it is connected to the motor pump. Its output must also be connected to the swivel.

Features of the drilling fluid

The washing liquid, which is located in the pit, is carried away by the motor pump and is sent to the well under high pressure. The solution flushes the slag that is formed during drilling, it simultaneously cools the tool and grinds the walls of the well. As you progress, the working column is built up by sections of the bars. Once the optimum depth is reached, the well is flushed, a swinging pump is installed in it.

Preparation for works

If you decide to drill wells for water with your own hands, then you need to prepare the equipment, as it stands MBU or a small-sized installation. If you believe that the drilling process is accompanied by the use of cumbersome mechanisms, you will be surprised that the described device is an installation whose height is 3 m, while the diameter is only 1 m. The assembly structure has the following components:

• A metal collapsible frame;
• Winch;
• swivel;
• Water pump;
• Drill rods;
• Control unit for the installation.

In addition, the following tools are used: the drilling tool, the motor, the drill for passing the soil hoses, the latter of which feed the water from the motor pump to the swivel. The motor is required to transfer force to the drill. As for the swivel, it is a working circuit assembly that provides the attachment of the rest of the parts.

The pressure in the system is maintained thanks to a water pump. If we examine the drill in more detail, it can be petal or exploratory. The formation of the column occurs with the help of drill rods. Considering the equipment for drilling wells into water, you will realize that you also need a current converter. It is necessary for the supply of electricity to the equipment.

Additional Tools

We must also prepare a winch, which will raise and lower the type-fitting pipes. The device can become part of the MBU. Buying gasoline motor pump, with which you will pump the drilling fluid, you should prefer a powerful unit, because the load will be quite impressive. Among other things, you should prepare a filter, casing and a small tool, namely:

• Manual clamp;
• A transfer fork;
• key.

Technology of work

The technology of water well drilling into water assumes the determination of the depth of the aquifer. This will allow you to assess the complexity of the work and think about how much casing is needed. You can get acquainted with the specifics of the local soil by contacting the land authorities. Even if digging is shallow, you should get a document from the center of sanitary and epidemiological conclusions.

It is important to determine the source of water, from where the liquid for the solution will be taken. Depending on the depth of the well and the composition of the soil, it may take 5 to 20 m ^{3 of} water to operate. The manual hydro-drilling in the next stage involves the preparation of the site. To do this, masters need to stock up on water. It is necessary to prepare containers, the volume of which is 2 m ³ . You can dig a pit for 5 or more cubic meters by treating its walls with a solution of clay. After this, the pit can be filled with water.

At the next stage, the MBU is installed. It's quite easy to assemble it, it will take about an hour. As the basic condition is mounting on a strictly horizontal surface. Even if there is a slight skew, then you will not be able to install the casing. Having deviated from the design of 1.5 m, it is necessary to prepare the technological grooves, which are called pits. They will contain a washing solution.

Additional recommendations

If you perform manual hydroboration of wells on water, two pits should be prepared. One becomes a filter, its length should be 0.7 m. A somewhat larger size will have a main pit, it should be located further. It is connected to the filter by a tray or trench.

Near the main pit there will be a motor pump. From its outlet, it is necessary to remove the hose, which is lowered into the main pit. A hose extends from the drilling rig to the equipment outlet. It connects to the swivel with a barbell. The drilling mud will flow through the swivel into the well.

Features of hydro drilling

If you need a well under the water, then it is necessary to start the hydroburst since the morning, as the process will take quite some time, sometimes it stretches for several days. The soil is different everywhere, accordingly, there may be some nuances in working with it. To drill in sandy soil, it is necessary to prepare a huge amount of water, since sand absorbs a lot of liquid.

Before starting manipulations, care should be taken to have a clay solution. In the pit with water for this, clay is loaded, which is mixed with a mixer. Consistency should ultimately resemble kefir. Such a drilling mud will enter the well and will not go into the sand, but will gradually clog the walls, forming a vessel. When a well is drilled under water, it is necessary to check whether the winches are working, and also the pump for pumping out water. In the process of piercing the soil from the sand stops are unacceptable. The casing is lowered immediately, otherwise there may be collapses, the work will have to start anew.

How to avoid mistakes

Quite often, the drilling of wells under water is carried out by the owners of their own houses. The procedure is not complicated. The drilling mud will flow into the hoses using a motor pump . Liquid enters the rod through the swivel, it will go to the working borer. The solution will grind the walls, hardening them. As soon as the liquid has been worked out, it is taken to the pit. In the tank, the soil settles to the bottom, while the solution flows into another pit. In this case, it can be used again.

When drilling wells under water, it is important to remember that the composition of the solution will depend on the variety of soil. If the soil changes during operation, it is necessary to make adjustments by changing the composition of the washing liquid. Continue drilling until the aquifer is reached. If the bar is not enough, you can add additional, until you can not go to clean water. Usually manufacturers of drilling rigs guarantee that they will work at a depth of 50 m. However, as practice shows, it is possible to penetrate with the help of such units to a depth of up to 120 mm. Once the aquifer has been reached, the well should be washed with a large volume of clean water.

Conclusion

If the wells are drilled with water by their own hands, then after the washing the rod should be removed. If the recovery is rather difficult, the flushing was not sufficient. Now you can start installing casing. Drilling of wells for water with their own hands sometimes involves the use of asbestos-cement, metal or plastic pipes. The latter variant is more widely spread, because it is longevous, does not undergo deformation and corrosion.
