Abstract

The invention relates to a reverse slope tunnel drainage and purification system and method, and belongs to the technical field of water supply and drainage. The reverse slope tunnel drainage and purification system comprises a drainage device, a movable medicine chest, a control system and multiple stages of water collection pits. The drainage process of water in a tunnel is achieved through the multiple stages of water collection pits, water in a clean water pool is pumped into the previous stage of water collection pit through the water collection pit close to a tunnel face, and water in the tunnel is drained out of the tunnel through stage-by-stage water pumping. Construction waste water at the tunnel face is pumped into a waste water treatment pool of the water collection pits through a water inlet pump, waste water treatment agents are put into the waste water treatment pool through the movable medicine chest, and the waste water flows into the clean water pool after being treated and then is drained out of the tunnel stage by stage through a water pump together with mountain burst water flowing into a central drainage ditch. Automatic adjustment of the efficiency of the drainage system is achieved through the variable-power water pump and a flow meter, and the reverse slope tunnel drainage and purification system and method have the advantages of reducing manpower input and saving electric power.

Description

technical field [0001] The invention belongs to the technical field of water supply and drainage, and relates to a drainage and purification system and method for reverse slope tunnels. Background technique [0002] During the construction of tunnel engineering, drainage is an important task, especially when the line is constructed along the downhill direction, the groundwater and construction wastewater cannot be discharged naturally along the designed side ditch and central drainage ditch, but along the downhill If the direction converges towards the face of the face, it will not only seriously interfere with normal construction such as excavation and support, but also cause the rock mass of the face of the face to soften if it is serious. Surrounding rock collapse and other issues. [0003] On the other hand, during the construction of reverse-slope tunnels, construction water, seepage water from the face of the tunnel, and water in the central drainage ditch of the line...
