Water inlet structure of tailing pond flood drainage system

Abstract

The invention discloses a water inlet structure of a tailing pond flood drainage system. The water inlet structure comprises overflow towers, wherein the overflow towers comprise tower walls and baffles, tower cavities are defined through the tower walls, the bottom ends of the tower cavities communicate with a drainage groove obliquely formed in the surface layer of a bank slope of a tailing pond, the positions, communicating with the drainage groove, of the bottom ends of the tower cavities are provided with communicating holes, openings communicating with the tower cavities are formed in the top ends of the tower walls, notches communicating with the tower cavities are formed in the tower walls, and the notches extend upwards from the lower ends of the tower walls to the top ends of thetower walls; and N baffles are arranged, the N baffles are correspondingly arranged and spliced upwards from the bottom ends of the notches in a step-by-step mode and are detachably arranged in the notches as the water level height of the tailing pond is increased so as to seal the notches step by step from bottom to top, and N is a positive integer greater than or equal to 1. According to the water inlet structure of the tailing pond flood drainage system, the baffles are convenient to disassemble and assemble, water sealing can be achieved, the plugging operation is simple and safe, the plugging quality is high, and the drainage effect is good.

Description

technical field [0001] The invention relates to the technical field of drainage of tailings ponds, in particular to a water intake structure of a tailings pond flood drainage system. Background technique [0002] Tailings ponds generally have a total height of tens of meters to hundreds of meters. In order to ensure the safety of tailings ponds, flood drainage systems must be installed in tailings ponds. The commonly used flood drainage system inlet structures are drainage chutes or drainage wells. [0003] The drainage chute is generally a rectangular cross-section, and can be set as a single or double grid according to the required discharge volume. During the operation, the cover plate is gradually used to cover and retain the water, and the discharge is from the side wall of the chute below the water level and the upper edge of the cover plate. . The drainage chute adopts cover plates to gradually block and retain water. Underwater operation, the sealing quality is poor...

AI Technical Summary

Problems solved by technology

The drainage well adopts arch plates to block and retain water step by step. It is an underwater operation, and the sealing quality is poor. The gaps between the arch plates often leak water and sand, and the arch plates cannot be disassembled after sealing

After the drainage wells of this level are used up, due to the high derrick of the drainage wells, the plugging operation is difficult and unsafe

The water inlet of the flood drainage system is not sealed tightly, and water and sand leaks, which will make the maintenance and inspection of the entire flood drainage facility difficult, and will cause environmental pollution to the downstream of the flood drainage facility outlet
