Abstract

DRAINAGE SYSTEM, which includes an open conductive channel and a closed collector-drainage network, is made with a reverse slope, characterized in that, in order to reduce the cost of cleaning drains by their & and the end of the closed conductive channel is provided with valves and brought into an open collecting manifold.

Description

The invention relates to land reclamation and can be used as a drainage of agricultural land.

A known drainage system includes an open conductive channel and a collector-drainage network laid down with a straight slope ij.

The disadvantage of the known drainage system was the e, the irregularity of the land masses.

Closest to the invention is a drainage system, comprising a conduction channel openings and a closed collector drainage system (network), made with a reverse load of 1 2j.

The disadvantage of the data system. The degree of sedimentation of drains with a prevailing gradient is due to low (0.2–0.3 m / s) transport speeds of water in drains, which requires a large amount of cleaning costs.

The purpose of the invention is to reduce the cost of cleaning drains by prokvvki

The goal is achieved by the fact that the wire f (the th channel is closed, and the source parts of the drains and the end of the closed conductive channel are supplied with valves and brought out of the KfMMTbM collector collector.

On (. 1 the proposed drainage system is shown, top view of j. In Fig. 2 - the same, side view.

The drainage system includes drains t connected to a closed conductive channel 2, the end 3 of which is equipped with a valve 4 and brought into an open collecting manifold 5. The drains 1 are equipped with valves 6 installed on their source parts 7 and brought into the open collector 5.

The drainage system works as follows.

 The movement of water in the drain 1 has a pressure character when the valve 6

at the source parts 7, and the valve 4. at the end 3 of the closed conductive channel 2 is in

open state. The water from drains 1, entering the closed conductive channel 2, is discharged through its end 3 and the open valve 4 into the open assembled collector S..

The draining of the drains is done by passing through them the increased flow rates of the drained water. For this, the water drained by the entire drainage system is transported from the closed conductive channel 2 to one or several drains 1, which must be washed and then the water flows through the source parts 7 and the open valves 6

in the open collector 5, while on the remaining drains and end 3 of the closed conductive channel 2, the sliders are closed

condition. Moreover, the number of drains with open valves must be less than the number of drains with closed sliders.

The efficiency of the installation in the proposed drainage system is high, as it is provided with a capacity of water transporting speeds, which arise due to high costs combined with the direct draft of the drainage in relation to the open collector. ,

.

The flow rate transported through the pipe is 5 da, or) the swept drains can be adjusted by changing the ratio of the number of drains with open and the number of drains with closed advise.

The feasibility of applying the invention is driven by a reduction in operating costs associated with the cleaning of rents.
