Abstract

This invention relates to the field of land reclamation. The purpose of the invention is to reduce the cost of operating the system. The drainage system includes drains connected to the collectors of the drainage system 2, which are connected to channel 4 through wells 3. Pipeline 5 is laid below the channel channel level, crossing each well 3. Pipeline 5 is laid with a slope corresponding to the slope of the bottom of channel 4, and the mouth part of it performed with elevated slope. The walls of the pipeline 5 are made waterproof. In each well 3 there is a drain pipe 6 connecting pipe 5 with water in well 3 and channel 4. 3 sludge.

The invention relates to land reclamation and can be used in the construction of a drainage network.

The purpose of the invention is to reduce the cost of operating the drainage system.

FIG. 1 shows the proposed drainage system, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The drainage system includes drains 1 connected to the collectors of the drainage system 2, which through wells 3 are connected to channel 4. Below the level of the channel of channel 4, pipe 5 is laid, intersecting each well 3. Pipe 5 is laid with a slope corresponding to the bottom slope of the canal and the well do not develop a water canal, and the mouth of it is made with a grown, increased slope.

5 waterproof, for example polyethylene. In each well 3 there is a drain pipe 6 connecting pipe 5 with water in well 3 and channel 4.

The drainage system of the proposed drainage system takes place both through pipeline 5 and channel 4. When the flow does not exceed the carrying capacity of pipeline 5, water from drain 1 through collecting, or drainage system 2, goes to well 3, from which b in the pipeline 5, and from it into the water intake.

When the flow exceeds the water inlets in the wells and at the bottom of the channel and their siltation, the well is flushed at maximum costs due to an increase in water velocity at the outlet with pressure and with forced suction due to the siphon effect.

Claims (1)

Invention Formula Drainage system, including drains, collectors, each of which is connected to the channel by means of a well located under its bottom, and a water intake, characterized in that, in order to reduce the redness of the pipeline 5, the level of the strokes for the operation of the system, wells the water in the wells 3 rises, and the hydrostatic pressure in the pipeline 5 increases. In the future, the water can be poured into the channel 4, through which it descends into the water intake. The rest of the water enters the water intake through pipeline 5, interconnected by a pipeline laid with a slope corresponding to the channel slope, with the mouth of the pipeline has an increased slope, and the pipeline is connected to the wells by means of drain pipes. 0 at the same time, due to the increased slope of the mouth of the waterproof pipe, water is drained through the pipe with a siphon effect. The siphon effect and the increased hydrostatic pressure provide an increase in the flow and speed of water throughout the pipeline 5, which contributes to the removal of sediment from wells 3. When the amount of water entering the drains 1 and collectors 2 decreases, the water level in the canal drops until the wells 3 are completely empty. Emptying the wells 3 and the mouth of the collectors 2 prevents them from silting, because in the absence of stagnant water „, the water in the wells and at the bottom of the channel and their sedimentation, as well as the flushing of the well is ensured at maximum flow rates due to an increase in water velocities during discharge with pressure and with forced suction due to the siphon effect. Invention Formula The drainage system, which includes drains, collectors, each of which is connected to the channel by means of a well located under its bottom, and a water intake, characterized in that moves to operate the system, wells interconnected by a pipeline laid with a slope corresponding to the channel slope, with the mouth of the pipeline has an increased slope, and the pipeline is connected to the wells by means of drain pipes.
