Double-wing wedge-shaped cover plate of novel chute flood drainage system

Abstract

The invention discloses a double-wing wedge-shaped cover plate of a chute flood drainage system, which is characterized in that it includes a tank body and a cover plate above the tank body, the tank body and the cover plate are spliced ​​in sections, the uppermost cover plate is a double-wing wedge-shaped cover plate, One end of the double-wing wedge-shaped cover plate is a wedge-shaped water inlet. The advantage of the invention is that: the flow capacity of the chute is increased, and the volume of the chute can be reduced under a certain requirement of the flow capacity, which can greatly reduce the engineering quantity. In addition, the size and weight of the concrete arch cover will be reduced, and the installation and disassembly during normal operation and management will be easier; the split double-wing wedge-shaped cover connected by connecting pins is easier to disassemble than the arch cover. The cover plate brings many aspects of economy, safety and convenience to the chute.

Description

technical field [0001] The invention relates to an arched cover chute flood discharge or drainage system for tailings ponds, slag ponds or small mountain pond reservoirs, especially those tailings ponds with insufficient or limited overflow water depth for flood discharge or drainage and slag library. . Background technique [0002] Chutes are the most commonly used flood discharge or drainage structures in tailings ponds, slag ponds and small pond reservoirs, especially tailings ponds. At present, there are more than 20,000 tailings ponds in China, of which more than 70% are medium Small tailings ponds, and small and medium tailings ponds mostly use chutes as flood drainage systems due to reasons such as clarification distance and operation management. In addition, some large tailing ponds use chutes as daily production drainage facilities in conjunction with flood drainage wells. The chute adopts an arched cover plate considering the reason of stress, and the arched cov...

AI Technical Summary

Problems solved by technology

But its biggest disadvantage is that the discharge capacity is small, especially when the overflow water depth is low, and most tailings ponds are affected by the clarification distance, dry beach slope, minimum dry beach length and safety superelevation, and the maximum overflow water depth is subject to greater restrictions

In order to increase the discharge capacity, at present, the volume of the chute is mostly increased, or double-cell or multi-cell chute is used, but these measures are actually less effective in the case of low overflow water depth, and the twice the engineering volume is only Can not achieve 1.2 to 1.3 times the effect
