Water is an indispensable part of all living things. It plays an important role in human life. For millennia, people learned to drill wells for water. More than 90% of fresh water is hidden in underground reservoirs. For In order to extract life-giving water from the ground, people are digging wells and bore wells. Methods of drilling a lot, but they depend on many factors.
For example, the type of land – rocky or loose; depth groundwater; purpose well. To date, there is a cable drilling, cable rotary drilling, hydraulic drilling and others. All of them are separated in time drilling, technological features used equipment. Cable-drums rigs allow you to work in any soil. Particularly well established, this method of drilling in rocky rocks. Drilling depth Well cable-way is 100 meters or more. The principle of operation is based on the lifting and lowering a sharp drill chuck. As a result of the drilling chuck the rock breaks into small pieces.
Destroyed rock is extracted from wells by bailer. In the process of drilling a borehole casing is immersed, well cemented. The purpose of casing and cementing is to prevent the crumbling walls of the borehole. In some cases, pose well filters. They are intended to provide additional protection from falling into the water, sand, pebbles and other impurities. Used for water abstraction borehole pumps. The pump is chosen according to well depth. The pump is placed on the surface of the earth around the well, if it is shallow. If the well is 10 meters in depth, the pump is suspended in the wellbore. An indispensable condition for an excellent quality of the final hole – her purity and integrity. Can not be allowed to well animals, avoid getting into her trash and organic waste. Usually well placed on the dais, to prevent it waste of surface water. Constantly need to check the quality of water in the well and disinfect the water. Nowadays with the development of low-rise private housing water well drilling was a good development. Many owners of private cottages and the villagers themselves bore wells for water supply. For this purpose handheld rigs, allowing drill anywhere, even in small areas near the house.
