Abstract

The invention relates to land reclamation and can be used on closed drainage systems. The purpose of the invention is to accelerate the start of drainage work in the spring. The drainage well (K) includes a housing 1 equipped with a cover 2. In K there are inlet 3 and outlet 4 collectors. In crater 2, a hole 5 is made, in which a ventilation pipe 6 is installed, the movable end 7 of which is provided with a deflector 8. The diameter of the hole 5 is smaller than the outer diameter of the deflector 8. During the period of negative temperatures in K, ice plugs 10 and 11 occur. atmospheric air, the movable end 7 of the pipe 6 is moved to position b and secured with a latch 9. When the wind deflector 8 flows around the cavity of the pipe 6, the pressure is reduced compared to the atmospheric pressure. Cooled to 0 ° C, air from K enters pipe 6 and is discharged through deflector 8 to the atmosphere. In the cavity K through the hole 5 enters the warm atmospheric air. A stream of atmospheric air, the temperature of which is significantly higher than 0 ° C, flows around the surface of the ice plug 11, causing its accelerated melting. Thus, the collector 4 coming out of K is freed from the ice plug and freely drains the drainage water flowing into K from the collectors. 1 il. (L Wind Sv JV 05 O5

Description

The invention relates to land reclamation, and can be used on closed drainage systems, in drainage well structures.

The purpose of the invention is to accelerate the start of drainage work in the spring.

The drawing shows a longitudinal section along the axis of the drainage well.

The drainage well includes a cylindrical body 1, provided with a cover 2 and inlet 3 and outlet 4 collectors. The lid 2 has a hole 5 in which a telescopic ventilation pipe 6 is installed, the movable end 7 of which is provided with a deflector 8. The diameter of the hole 5 is smaller than the outer diameter of the deflector 8. The pipe 6 is equipped with a retainer 9. As a result of freezing of water accumulated in the well, ice forms on the cork 10. Ice on the plug 11 is formed due to condensation of vapors and freezing of ground and drainage water entering the well during the period of negative temperatures.

Drainage well works as follows.

During the period of positive temperatures of atmospheric air, the movable end 7 of the pipe 6, passed through the hole 5 in the lid 2, is lowered to the lower position and indicated by the dotted line. Moreover, since the diameter of the hole 5 is smaller than the outer diameter of the deflector 8, the deflector 8 blocks the hole 5 in the lid 2 of the drainage well, preventing precipitation, dust and debris from entering the well.

After passing through the autumn flood, the volume of water remains in the sump of the drainage well, equal to the mark of the lowest point of the outgoing collector 4. When negative temperatures occur and the well freezes, this water freezes, forming an ice plug 10. Those entering the well during negative temperatures drainage and groundwater, as well as condensing water vapors, freeze, forming an ice plug 11 over the ice plug 10, which blocks the outlet of the well from the well collector 4, and sometimes the incoming 3.

When the spring period comes and positive average daily temperatures of atmospheric air are established, the movable end 7 of the tube 6 is extended to the extreme upper position b and fixed in this position by the fixer 9. When the deflector 8 flows around the wind flow of the air, a reduced pressure is created in the cavity 6 ,

5, as a result, the air cooled to 0 ° C from the well enters the pipe 3 and is released through the deflector 8 into the atmosphere, and enters the cavity of the drainage well through the hole 5 in the cap 2, along with warm atmospheric air.

0 The flow of atmospheric air, the temperature of which is much higher than 0 ° С, flows around the surface of the ice plug 11, causing accelerated its melting. Thus, the collector coming out of the well 4 is released from the ice plug, and freely drains the drainage water entering the well.
