The autonomous water supply system quite often acts as the only way to arrange water supply for summer cottages and country houses. A well is selected as a source, which is equipped on the site. Owners, as a rule, reveal a desire to carry out the development process with minimal losses to the territory, this is especially true when the exterior is ennobled. It is also important to save money. Of course, you will need special equipment and additional tools, but it is important to decide whether you will manage the work yourself or entrust the work to specialists.
Technology description
An excellent solution in this case is hydraulic drilling of water wells, such work can be done by hand. The method is based on the technology of destruction of soil rocks using a drilling tool and liquid. The load can be provided by drilling equipment and the weight of the rod, with the help of which flushing fluid is pumped into the well under pressure, it is also called drilling fluid. It is a suspensionconsisting of water and clay.
It is necessary to additionally dig pits near the drilling site, the size of which is 1x1 mm. They are filled with drilling fluid, interconnected by trays. The drilling fluid is fed to the bottomhole. To do this, the outlet hose is immersed in a pit, but it is first connected to a motor pump. Its output must also be connected to the swivel.
Features of using drilling mud
The flushing liquid, which is in the pit, is carried away by the motor pump and directed to the well under high pressure. The solution washes out the slag that is formed during drilling, it simultaneously cools the tool and grinds the walls of the well. The work string is built up with sections of rods as it moves. As soon as the optimum depth is reached, the well is flushed and a swing pump is installed in it.
Preparation for work
If you decide to carry out hydro-drilling of water wells with your own hands, then you need to prepare equipment, it is an MBU or a small-sized installation. If you think that the drilling process is accompanied by the use of bulky mechanisms, you will be surprised that the described device is a device whose height is 3 m, while the diameter is only 1 m.
- metal collapsible frame;
- winch;
- swivel;
- water pump;
- drill rods;
- blockplant management.
Additionally used: drilling tool, engine, drill for passing the soil hoses, the latter of which supply water from the motor pump to the swivel. The engine is needed to transfer force to the drill. As for the swivel, it is a work path assembly that provides fastening to the rest of the parts.
The pressure in the system is maintained by the water pump. If we consider the drill in more detail, then it can be petal or exploration. The formation of the column occurs with the help of drill rods. Considering equipment for hydro-drilling water wells, you will understand that you will also need a current converter. It is necessary to supply electricity to equipment.
Additional tools
We also need to prepare a winch that will raise and lower stacking pipes. The device can become part of the MCU. When purchasing a 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 pipes and small tools, namely:
- manual clamp;
- transfer plug;
- key.
Work technology
The technology of hydrodrilling water wells involves determining the depth of the aquifer. This will allow you to assess the complexity of the work and think about how many casing pipeswill be needed. You can get acquainted with the specifics of the local soil by contacting the land authorities. Even if the digging is shallow, you should get a document from the center for sanitary and epidemiological conclusions.
It is important to determine the source of water from which the liquid for the solution will be taken. Depending on the depth of the well and the composition of the soil, work may require from 5 to 20 m3 of water. Manual hydraulic drilling at the next stage provides for the preparation of the site. To do this, the masters need to stock up on water. Containers should be prepared, the volume of which will be 2 m3. You can dig a hole of 5 or more cubic meters by treating its walls with a clay solution. The hole can then be filled with water.
The next step is to install the MBU. Assembling it is quite simple, it will take about an hour. The main condition is installation on a strictly horizontal surface. Even if there is a slight skew, it will not be possible to install a casing pipe. Deviating from the design of 1.5 m, it is necessary to prepare technological recesses, which are called pits. They will contain the flushing solution.
Additional recommendations
If you will be manually drilling water wells, you should prepare two pits. One will act as a filter, its length should be 0.7 m. The main pit will have a slightly larger size, it should be placed further. It is connected to a filter tray or trench.
A motor pump will be located near the main pit. From its outlet it is necessary to remove the hose, which descends into the main pit. A hose is pulled from the drilling rig to the outlet of the equipment. It connects to the swivel with a rod. Drilling fluid will flow into the well through the swivel.
Features of hydrodrilling
If you need a well under water, then you need to start hydro-drilling in the morning, as the process will take quite a long time, sometimes it stretches for several days. The soil is different everywhere, respectively, there may be some nuances in working with it. Drilling in sandy soil requires a huge amount of water to be prepared, as the sand absorbs a lot of liquid.
Before starting manipulations, you should take care of the presence of a clay solution. For this, clay is loaded into a pit with water, which is mixed with a mixer. The consistency should eventually resemble kefir. Such a drilling fluid will flow into 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 operational, as well as the pump for pumping water. In the process of punching soil from sand, stops are unacceptable. The casing pipe is lowered immediately, otherwise collapses may occur, the work will have to be started again.
How to avoid mistakes
Quite often, drilling wells under water is carried out by the owners of their own homes. The procedure is no differentcomplexity. Drilling fluid will be supplied to the hoses with the help of a motor pump. Liquid will enter the rods through the swivel, it will go to the working drill. The solution will grind the walls, strengthening them. As soon as the liquid is used up, it is taken to the pit. In the tank, the soil will settle to the bottom, while the solution will flow into another pit. It can be used again in this case.
When drilling wells under water, it is important to remember that the composition of the solution will depend on the type of soil. If the soil changes during operation, it is necessary to make adjustments by changing the composition of the washing liquid. It is necessary to continue drilling until the aquifer is reached. If the rod was not enough, you can add more until you can reach clean water. Typically, manufacturers of drilling rigs guarantee that they will work at a depth of 50 m. However, as practice shows, it is possible to break through with the help of such units to a depth of up to 120 mm. Once the aquifer has been reached, the well should be flushed with a large volume of clean water.
Conclusion
If you are drilling water wells with your own hands, then after washing the rods must be removed. If lifting is difficult enough, flushing was insufficient. Now you can start installing the casing pipes. Do-it-yourself hydro-drilling of water wells sometimes involves the use of asbestos-cement, metal or plastic pipes. The latter option is more widespread, because it is durable, does not deform andcorrosion.
