Description

The invention relates to hydraulic structures intended for the extraction of groundwater.

The Abyssinian or Norton artesian well is known, consisting of a pipe with a diameter of 25-45 mm reaching the aquifer, equipped with a sieve-shaped tip, with an installed pump (ru.m.wikipedia.org).

A device is known for supplying water from a well to a tower, including a submersible pump with a non-return valve, connected to the tower by means of a pressure pipe with an upper water supply to the tower, a valve and an automatic drain valve (RF patent No. 2222671, EV 3/06, 2004).

Closest to the claimed device are the key wells and prefabricated shaft type, consisting of reinforced concrete rings or made in the form of a log house and installed vertically in the mine (www.aquacop.ru).

A known water filter comprising a housing with intake and exhaust manifolds with perforated tubes installed in the housing, the tubes are closed by valves opening under the pressure of the supplied water (SU 20090045128 A1, B01D 35/30, 2009).

The closest in technical essence is a multi-level water sensor, consisting of pipes connected to filters placed in a common shaft, while the shaft pipes are separated from each other by a substrate (DE 3012709 A1, E21 B 47/04, 1981).

The disadvantages of the known devices are the impossibility of producing a well without special equipment for installing concrete rings or logging, as well as clouding of water with bottom sediments during repeated extraction of portions of water with a bucket or from the return of a stream of water from the pump.

The objectives of the invention is to simplify the manufacture of the well and the prevention of water pollution during repeated extraction of individual portions of water.

The solution of these problems is achieved by the fact that the well is made in the form of a shaft with well elements installed in it in the form of pipes, and it is equipped with a coupler, the pipes of the shaft form combinations, while the coupler ensures the retention of pipe combinations, and each of the pipes is a separate discrete well.

The invention is illustrated by graphic materials, where in FIG. 1 shows a well, a longitudinal section; in FIG. 2 - aerial part of the well, top view.

The well is made in the form of pipes 1 installed in the well shaft. Pipes 1 can be made of asbestos cement, asbestos cement with a plastic coating, metal, metal with a plastic coating, plastic and other materials. The diameter of the pipes 1 can be from 20 cm to 50 cm or more, depending on whether it is intended to use a well with a pump or with a bucket to extract water. Pipes 1 can be round or square in cross section, and also have any other shape. Pipes 1 are installed vertically parallel to each other and can form any shape of a well with their combination: square, rectangle, triangle, circle, pyramid, etc. To maintain the given shape of the well and prevent the displacement of pipes 1 relative to each other, a screed 2. In this case, the total area of the well formed by a set of pipes 1 remains large and sufficient to collect the required amount of groundwater.

The well is made and works as follows.

If the well is square in cross section, the square can be formed by four, nine, sixteen, etc. pipes 1.

A user can dig a well without special skills. Tearing out a mine of a certain shape under the pipes 1 to the depth of groundwater, the user independently installs pipes 1 into the shaft one by one, pouring crushed stone to the bottom and sides of the pipes 1. In the aboveground part of the well, a screed 2 is installed, which prevents the displacement of the pipes 1.

Ground water accumulates at the bottom of each of the pipes 1 forming a well. To extract water, a submersible pump is lowered into pipes with a small diameter. For pipes of large diameter from 50 cm and more, buckets with a displaced center of gravity or with a small hole in the bottom of the bucket can be used.

After extracting water several times from one pipe 1 and seeing turbidity of water from bottom sediments, the user rearranges the pump in the adjacent pipe 1 or starts scooping up water from another pipe 1, repeating the procedure as necessary.

The technical result of the invention to simplify the manufacture of a well is ensured by the fact that its manufacture does not require special devices for lowering reinforced concrete rings into the shaft or professional skills of a carpenter in the case of a well being chopped from wood. The user can independently dig a shaft and install pipes of small weight in it.

The technical result of preventing water pollution during repeated extraction of individual portions of water from the well is achieved by the fact that the well is made of pipes, each of which is a miniature well. As the turbidity of water in one of the pipes of the well, the user begins to take water from other pipes forming the well.

The technical result was achieved by the implementation of a well for groundwater from separate discrete wells, each of which is formed by a separate pipe.
