(54) VERTICAL DRAIN

(57) The invention relates to the drainage of the soil and can advantageously be used for the drainage of hydraulic tailings. The purpose of the invention is to increase the efficiency of the drain operation by reducing clogging of the filtering material and silting the horizontal drainage pipe. The device consists of an outer frame 1, a filtering material 2 located between the outer frame 1 and the inner frame 3, a pipe 4 with nozzles 5 installed above the water collector 6, and a horizontal drain pipe 7 with a discharge pipe 8. Drainage water from the hydraulic dump flows through the outer the frame 1 into the filtering material 2, and then through the internal frame 3 into the catchment 6 and along the horizontal drainage pipe 7 is led out of the limits of the waste dump. In order to reduce collar of the filter material 2 through the pipe 4 installed along the entire length in the center of the inner frame 3, the pipe 8 is periodically supplied with water under pressure, which through the nozzles 5 acts on the filter material 2, washing out fine particles. 1 il.

The invention relates to the drainage of the soil and can be used for the drainage of the tailings and tailings of the beneficiation plants and mining enterprises.

The purpose of the invention is to increase the efficiency of the drain operation by reducing the clogging of the filtering material and silting the horizontal drainage pipe.

The drawing shows the vertical drain.

The device consists of an outer frame 1, a filtering material 2 located between the outer frame 1 and the inner frame 3, a pipe 4 with nozzles 5 installed above the water collector 6,

 and a horizontal drain pipe 7 with a pressure pipe 8.

The device works as follows.

Drainage water from the hydraulic dump enters through the outer frame 1 into the filtering material 2, which reduces the flow rate of drainage water, which prevents the removal of fine particles of soil from the body of the hydraulic dump and then through the inner frame 3 into the water collector 6 and through the horizontal drain pipe 7 limits of hydraulic dump. To reduce the mudding of the filter material 2 through the pipe 4, installed along the entire length in the center of the inner frame 3, and the pipe 8, periodically

water is supplied under pressure, which through the nozzles 5, which form the jets, flushes fine particles, collimate the filtering material 2, which, together with water, through the water collector 6, through the horizontal drainage pipe 7 flows outside the waste dump, which increases the efficiency of drains An increase in the volume of water in the drain provides an opportunity to increase the flow rate from the horizontal drainage pipe 7, the latter prevents its sedimentation by fine particles of soil and provides t constant performance.
