Independent drilling of wells requires significant physical effort, but has its advantages over machine drilling. These include the cheapness of the work, the ability to perform a well anywhere in the plot.

The working tool depends on the method of drilling, the composition of the soil, the depth of the aquifer. When working on clay soils, use the spiral brown (Schneck). The diameter of the bottom of the tool is from 45 to 85 mm, the blade length is from 250 to 290 mm. For impact drilling needed bobbin. On sandy soils, take a border made in the form of an eccentric. The tool length is about 700 mm, diameter - from 70 to 200 mm. The loose ground is removed by the venture (piston or ordinary). It weighs at least 50 kg, the maximum length of the device is about 2 m.

The auxiliary materials include steel pipes (knees) extending the working tool; Material for making goats or towing for fastening the winch; Small gravel, casing, winch, the truck for the export of soil should also be at hand.

Before starting work, prepare a section to drill. For a well, a depth of 3 m is enough to align the site and make a depression of a depth of 40 to 60 cm for the installation of the bora. For a deeper well, dig a pit to 2 M depth and 1.5 x 1.5 m wide, cover the wall by the boards. At the bottom of the casing tube, perform holes with a diameter of 5 to 7 mm at a length of up to 2 m.

Drilling Schneck is the simplest way to perform a well. For rotation of the working tool requires 1-2 people. Take me out for cleaning through several revolutions. Periodically increase its length with an additional knee-knee. After the appearance of water, remove several times and lower the rod, cleaning the well from the dirt. Install the casing pipe in the well, pour gravel between the pipe and the well.
5
Lower the centrifugal pump to reject dirty water in the well. During cleaning, plunge gravel between the pipe and the well. Cleaning lasts until pure water appears. Then lower the reservation filter on the bottom or pour a small gravel with a layer from 20 to 30 cm. Rent a liquid again to obtain clean water. This procedure repeat several times every hour.
6
After a day, check the water level in the well. Optimal - a few meters, water consumption - at least three cubic meters per hour. The gaps between the pipe and the walls of the well are filled with cement mortar to prevent dirty water from entering the well. Make a roof over the well. Install the pump for permanent operation.

For a deep well, a shock-rope method is recommended using a homemade rig. The thickness of the casing - more than 5 mm. At the bottom of the breasade cone, the diameter of which is more than 4-5 cm diameter. To connect to other pieces of pipes from the opposite side, cut the thread.
8
Place the pipe vertically, but fasten not hard. I lower the pipe in the pipe on the cable. Raise it as much as possible and release. The soil that will fall into the device must be raised and throwing away. Solid rock will pre-break the chisel.

Another option is a column drilling. For this method, a hollow tube is needed with a cutting crown fixed at the bottom. When rotating the pipe is immersed in the soil, moving the soil inside the pipe. Raise the pipe and select the sludge out of it. On the top of the pipe there are holes for attaching an extra rod. It is convenient to use the extension from 1 to 1.5 m. The method is suitable for loose soil.
When drilling, stock patience. A wells for a well can be 10 m depth, and there is nothing at this depth. It should be remembered that water is everywhere, it should not be disappointed in advance in the conceived.
