Temporary water retaining apparatus for rapidly handling problem of water and mud bursting in tunnel

Abstract

The invention discloses a temporary water retaining apparatus for rapidly handling the problem of water and mud bursting in a tunnel. The apparatus is provided with a water bag which is used for filling the inside with water for blocking gushing water or projecting mud soil generated in case of seepage in the tunnel and an air bag which is used for inflating air inwards for blocking the gushing water or the projecting mud soil generated in case of the seepage in the tunnel, and the water bag and the air bag are connected in an end-to-end manner and are connected through a flange connecting mechanism. The end, which is away from the air bag, of the water bag is respectively provided with a water filling port, a water pressure alarm for detecting water pressure inside the water bag and giving an alarm, and a front anchoring joint is disposed at the center for connection with an anchor pole or a fixation facility inside the tunnel. The end, which is close to the water bag, of the air bag is respectively provided with a gas injection port and a gas pressure alarm used for detecting gas pressure inside the air bag and giving an alarm, and a rear anchoring joint for connection with the anchor pole or the fixation facility in the tunnel is arranged at the center of the end, which is away from the water bag, of the air bag. The rubber bag capsule provided by the invention is simple in structure, convenient to manufacture and easy to operate, and can realize reutilization.

Description

technical field [0001] The invention relates to a device for treating water gushing and mud gushing in tunnels. In particular, it relates to a temporary water retaining device which can be filled with water (air) and is used for quickly dealing with the problem of water and mud inrush in tunnels. Background technique [0002] In recent years, with the development and utilization of underground space, safety issues in the construction and operation of urban underground railways have attracted much attention. However, the area where the tunnel passes will inevitably have aquifers or areas where cracks in the rock formations develop, and the probability of leakage or even water gushing and mud bursting during the construction or operation of the tunnel is very high. Such accidents are characterized by suddenness and high hazards. Once they occur, they will submerge or bury equipment, block tunnels, affect construction progress and construction plans, and cause heavy casualties...
