Anti-blocking guided drainage device for bridge drainage

Abstract

The invention discloses an anti-blocking guided drainage device for bridge drainage. The anti-blocking guided drainage device for bridge drainage comprises a reserve mining block and a water pump water absorption tube; a stoping mining block is arranged on one side of the reserve mining block; a mining tunnel is arranged around the reserve mining block; one side, away from the reserve mining block, of the stoping mining block is provided with a drainage pipeline; a ventilating duct is arranged above the stoping mining block; the drainage pipeline is arranged above both the stoping mining blockand the reserve mining block; a water sump is arranged below the stoping mining block; a water sump water inlet pipe is arranged on the front surface of the water sump; a liquid level detector is arranged on one side of the interior of the water sump; and a water sump protective screening is arranged, close to a position above the liquid level detector, inside the water sump. Workers passing theperiphery of the water sump can be conveniently protected by the water sump protective screening; the problem of safety accidents caused by too deep water of the water sump is avoided; meanwhile, orefalling into water can be conveniently cleared; and the problems that stones falling into the water are difficult to clear and influence the water storage of the water sump are avoided.

Description

technical field [0001] The invention belongs to the technical field of mining, and in particular relates to an anti-blocking guiding type drainage device for bridge drainage. Background technique [0002] Mining engineering is divided into coal mines and non-coal mines. Mining (English name: ore mining) is the technology and science of mining mineral resources from the earth's crust or surface. Generally refers to the mining of metal or non-metallic deposits. In a broad sense, mining also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and handling process of materials. Mining industry is an important raw material extraction industry, such as metal ore is the main raw material of metallurgical industry, non-metallic ore is chemical raw material and building materials, coal and oil are important energy sources. Most ores need to be enriched by beneficiation before they can be used as industrial raw materials. [0003] The existi...

Problems solved by technology

[0004] The object of the present invention is to provide an anti-blocking guiding drainage device for bridge drainage, to solve the problem that the existing mining drainage device proposed in the above background technology has poor safety when used, and the staff is easy to fall into the drainage device when not paying attention. In the water tank of the device, at the same time, the large ore falling into the water tank will easily affect the water storage capacity of the water tank, which is not convenient for the normal drainage of the mine, and it is not convenient for the workers to carry out the construction safely, and the direct one-time drainage method is adopted. The problem of large water pump power requirements
