The invention relates to hydromechanization of earthworks and can be used to drain hydraulic dumps and tailings of processing plants and mining enterprises.

The aim of the invention is to reduce the cost of draining and accelerate the consolidation of the hydraulic dump.

The invention is illustrated in the drawing.

The discharge well comprises a housing 1, the middle part of which is located in the pulp, and the upper part is in the water, and the pipe 2 is concentrically mounted with the possibility of vertical movement with a gap in it. The middle part of the housing 1 and the vertical pipe 2 are perforated. The gap between them is filled with filter material 3. The vertical pipe 2 is equipped with a float 4, mounted on the rod 5.

The device operates as follows.

Water from the hydraulic dump passes through the middle part of the housing 1, the inner perforated pipe 2 and the filtering dusting of the filter 3 into the drainage collecting system of the water conduits, from where it is discharged outside the hydraulic dump. The float 4, under the influence of waves or fluctuations in the water level of the hydraulic dump, makes movements in the vertical plane and transfers vibrations through the rod 5 to the inner perforated pipe 2. from the hydraulic dump.
