Drilling a well with water under pressure with your own

Most often, the need to have a well in the area occurs after its partial or complete improvement. In this case, the land works, especially with the help of mechanized equipment, turn into a nightmare for the owners. Ruined trees, rumpled lawn, clay lumps and a pile of construction debris will spoil the mood of anyone.

But the well can be done in several simple ways, with a minimum of costs and damage. One of these methods is the drilling of wells with pressurized water, where she herself serves as a tool for extracting precious moisture. Moreover, this method will not require the involvement of workers; in your free time you will be able to do the useful work yourself.

What is MBU

Since the main tool in the work will be water, there is a functional mechanism that makes it work. Small-sized drilling rig (MBU) - a simple, mobile and easy to install device.

It consists of the following elements.

1. The basis is a solid collapsible metal frame.
2. Drilling device.
3. The engine that transmits to the drill effort.
4. Water pump to provide the necessary water pressure.
5. Winch.
6. Swivel - part of the working circuit, creating a sliding gear to the other elements of the device.
7. Petal or exploratory auger.
8. Transition hoses that feed water to the swivel from the pump.
9. Forming column drill rods.
10. The control unit of the unit.

Preparation for work

It is extremely easy to assemble the installation, even for a beginner. It will take no more than an hour and a minimum of free space on the site.

Assembly of equipment

In order to work fruitfully, avoiding all unforeseen failures, you should carefully consider the installation of the device.

Note! Drilling a well with water under pressure is effective in the presence of sandy, loamy or clayey soils. For stony fractions, this method is considered unsuitable.

1. Begin assembly with the base frame.
2. The next stage is the design of priyamkov - special technological grooves. They will contain the necessary working solution for hydrodrilling. The distance from the installation to the pit varies from 1 m to 1.5 m.
3. You will need two notches - the main and filtration. The latter is placed closer to the installation, with a depth and a pit width of about 70 cm. A shallow trench will connect it with the main pit, a meter depth and width.
4. Install a water pump. A hose is inserted at one end into it, the other end leads to the main pit. To the drilling device from the outlet port pull the supply hose.
5. The supply hose is connected to the swivel with a rod. The drilling fluid is then fed into the well through the swivel.
6. The treated drilling fluid will enter the filter pit from the well. At this stage, the earth, taken out of the well, will settle at the bottom, and the drilling solution will go into the main pit. It can then be used again for the operation of the mechanism.

Note! The composition of the working solution depends on the type of soil. The instruction warns that when changing the composition of the soil in the process of passing, the solution should be changed to the corresponding analogue.

Before starting work

Before you carry out drilling work, be sure to learn the specifics of your soil. At the same time it is worth finding out at what depth the water lies. The easiest way is to ask your neighbors, but geodesic specialists will give you more accurate information. The deeper the aquifer, the more casing is required.

Careful preparation is especially important if you are planning to do it yourself. Water analysis is also obligatory, it will be produced best in the nearest laboratory. Drinking water must meet all standards and requirements, otherwise you risk your health, dirt and harmful impurities will not slow down with a negative impact.

Another important nuance is site preparation and water storage. It is either collected in containers of at least two cubic meters in volume, or poured into a pit dug and plastered with clay solution.

After you can install the MBU, making sure that the device stood exactly. Even a small bias will not allow to insert a casing with high quality.

Drilling process

Professionals are advised to start work early in the morning. Depending on the difficulties encountered in the process, you will have to work for one or two days. It is easiest to work on light, sandy soils, clay counterparts will require a little more labor.

Stages of drilling

1. Prepare more water and knead the clay solution.
2. Pour the clay into the pit, cover with water and stir to a consistency of liquid sour cream.
3. Thus prepared solution for drilling a well does not penetrate through the sand, but gradually settles on the walls of the working hole. When drying, the clay forms a plastering of the walls, forming a semblance of a vessel.
4. Be sure to check before working all components of the installation mechanisms. They must function smoothly, as it is impossible to stop the drilling process.
5. After passing the first stage, immediately insert the casing. This is especially important with loose ground. Otherwise, the hole will be clogged with soil, and you will have to start all over again.
6. In the course of a hydraulic drive, a motorized pump supplies drilling fluid to the hoses. The mixture enters the rods through the swivel directly to the borax.
7. The solution performs several functions at once - cools and softens the work of the drill, lubricates and polishes the well walls, thereby strengthening them.

1. The spent liquid mixture is discharged to the filter pit. Here, the ground captured from the bottom of the well is deposited, and the purified solution will flow into the second pit along the chute.
2. Use the filtered solution again, repeating the operation.
3. Work until you reach an aquifer. As the work progresses, build up the bars until clear water appears.

Note! Manufacturers of MBU guarantee high-quality installation to a mark of 50 meters. But many users have learned from their experience that the mechanism copes well with drilling and up to 120 meters, without breakdowns and problems. So the price spent on a drilling device for a well is justified. The main thing is to strictly observe the installation technology and the process of passing.

Casing installation technology

When you have reached the water-containing layer, the well should be thoroughly rinsed with water. Now you can carefully remove the drill rods.

If they are pulled out with difficulty, it means that you have not washed the hole enough, therefore, it is better not to spare water.

1. Casing pipes are made of asbestos cement, plastic or metal. Plastic is considered the most simple, cheap and durable material.
2. If you have a shallow well, suitable pipes with a diameter of 116 mm. For deeper slaughter - 125 mm analogues. The optimum are walls with a thickness of 5 to 7 mm.

1. To improve the quality of water will help special slotted or sprayed filters. But you can make a simple, homemade filter.
2. With a fast water well filling the well, the device will have to be modified. Holes are drilled in its tip. Then, a tip is inserted into the pipe, and the pressure hose extending from the pump is attached to it.
3. Next, water is supplied with a maximum pressure. The casing pipe will easily enter the aquifer.
4. When the column is installed, do not interfere with pouring half a bucket of gravel inside the well. Get an additional filter.
5. Begin the next flushing of the well to blur the water carrier clogged with drilling mud. At the end of the column covered with gravel.
6. It is possible to lower the pump inside, but not against the stop, but just below the water level. Otherwise, the mechanism will not work long.

Conclusion

Drilling a well on the site with water is easy, as is the assembly of the installation. But, if you have poorly studied instructions or are not confident in your abilities, attract professionals.
