Abstract

The invention makes it possible to increase the efficiency of the periodic flushing of the drainage, the draining effect of the system, and to reduce the capital costs. The aim of the invention is to increase the efficiency of the system and reduce the coagulation. The drainage system includes drains 1, a collector 2, a storage tank 3 with a vacuum siphon device 4. The storage tank is sealed and provided with a connecting pipe 5 for tight connection via a coupling 6 to the mouth of the collector 2, a check valve 7 and a drain pipe 8 that is sealed with a valve ( cover) 9. The pipe 5 is connected to the storage tank 3 below the crest of the siphon 4 by the value of 4H, providing the calculated water filling of the collector 2 of the drainage system. The value of 4H is calculated by the formula ΔH = Α ^{. L.} J, where L is the length of the collector, m

J-slope, α-experienced coefficient. 1 il.

Description

The invention relates to agriculture and can be used in drainage amelioration for flushing drainage cavities from silting, speeding up the drying process and preventing coagulation,.

The aim of the invention is to increase the efficiency of the system and reduce the coagulation.

The drawing shows a diagram of the drainage system.

The system includes drains 1, a collector 2, a holding tank 3 with a vacuum device — a siphon C, a coupling pipe 5, a coupler, a return valve, for example, a spring-loaded valve 7, a drain pipe 8, a valve 9. The siphon comb 4 is not { the walls of the storage tank 3, and the inlet pipe is connected to the storage tank 3 below the crest of the siphon by the value h, determined by the formula

/ Jh,

where L is the length of the collector, m; I - collector bias, o - experimental coefficient equal to

0.2-0.8,

The drainage system operates as follows.

8, the period of over-wetting of the filtering water from the soil through drains 1, the collector 2 fills the storage tank 3 until the siphon C turns on, abruptly at high speed, discharges water from tank 3 and collector 2 of the sediment system that occurs in tank 3 with the onset of water discharge, the vacuum closes valve 7 and, with a complete discharge of water from tank 3, it propagates through the collector 2 and drains 1 into the surrounding space, increasing the water inflow to the drains and accelerating the drying process.
