Description

Fi.1

The invention relates to construction and can be used to drain the built-up areas of industrial sites of enterprises. -. .

Known radiation drainage containing a well with horizontal rays in difficult hydrogeological conditions, including a central well, a system of horizontal horizontal beams hydraulically connected to a well equipped with filter columns, / a system of vertical water wells drilled in the well placement zone, water supply pipes and pump for pumping water (1). . . ; .:. -. ;. - -:;

The disadvantage of this radiation drainage is insufficient durability.

The closest is radiation drainage, including a mine drain, radially placed and hydraulically; connected; connected with it, high-drainage drainage wells with filter columns, water--; feed pipes and water pump

(2) - i. .., W; Sh.,

The rest of the tccm of this beam drainage is that when draining poorly permeable clay soils with a large content of salt in high-well wells during the outflow of water at low speed occurs from none of the Yolnaya ShnGh; accumulation of salts in them, which reduces their operational reliability and longevity. ; The purpose of the invention is to increase the reliability and durability due to self-washing. //: Li ;. /./.-; . .., - :. -.... -. V ..

This goal is achieved by the fact that in a known radial drainage, including a mine shaft, horizontal drainage wells radially placed and hydraulically connected to it with filter columns, water supply coars and a water-lifting pump, the filter column of each well is equipped with a V-branch located at the mouth of the well Ying, the outlet of which is aligned with the upper generatrix of the near-barrel part of the filter column, while the V-shaped branch is equipped with a siphon, the intake end of which. lowered to the lower generatrix of the near-barrel part of the filter column, the outlet end of the siphon is discharged into the shaft shaft of the beam drainage, and the upper generatrix of the horizontal branch of the siphon is at the levels of the outlet of the V-shaped outlet.

Figure 1 shows the radial drain; figure 2 is the same, a top view.

The radial drainage contains a shaft 1, radially located and hydraulically connected to it horizontal drainage wells 2 with filter columns Zg, water supply pipes and a water lift pump. Filtration: the column 3 of each well is equipped with a V-shaped branch 4 located at the mouth 5 of the well 2. The outlet 6 of the outlet 4 is aligned with the upper generatrix 7 of the barrel part of the filter column 3. The V-shaped branch 4 is equipped with a siphon 8, the water intake pipe 9 of which , lowered to the lower generatrix 10 of the receiver part of the filter column 3. The drain tube 11 of the siphon 8 is brought into the shaft shaft 1, and the upper generatrix 12 of the central tube 13 of the siphon 8 is at the levels of the outlet Hole 6 of the V-shaped otode 4., ..: - ;.-.-., .. - Lucheva draene slave melts follows. First, the horizontal water is filled with drainage water about its complete flow through the filter

a saucer 3, constructed from the shaft shaft 1. This is achieved by the output; the hole 6 of the V-shaped branch 4 is aligned with the upper generatrix 7 of the filter column. In this mode of operation of horizontal well 2, siphon 8 placed is charged; on a V-shaped branch 4.; . After the horizontal well 2 is filled with drainage water to the full cross section, a siphon 8 is activated and the drainage water is discharged into the mine shaft 1 of the radiation beam. In this mode of operation of horizontal well 2, it is self-flushing. It is characterized by the fact that, as a result of an increase in the rate of flow of 2 drainage water from a hot well; due to its suction of siphoyo.m 8, salt particles are removed, which prevents their accumulation in horizontal well 2. When the level of drainage water in horizontal well 2 BEFORE the intake end of siphon 8 It is turned off. The self-washing process of b-well 2 is periodically ps-repeated. -: .. The proposed technical solution provides self-washing of the filter columns, increases the service life and reliability of horizontal wells during drainage of Owayiya of poorly permeable clay soils with a high salt content. .,.

Formula A was also invented by Luchev drain, which contains a mine shaft with horizontal radial axes drainage wells with filter columns inside, having upper and lower barrel parts forming them, water supply pipes and a water-lifting pump, and so on. which, in order to increase reliability and durability beyond

self-flushing, each filter column in the wellhead is equipped with a V-shaped outlet c. a siphon-nail having a water intake, central and drainage tube, while the outlet outlet is aligned with the upper generatrix of the near-barrel part of the filter column,

the siphon's intake pipe is located at the level outside the generatrix of the near-barrel part of the filter column, its spillway is brought into the shaft shaft, and the upper generatrix of the central tube is located at the level of the outlet of the V-shaped outlet.
