Abstract

The invention discloses an all-enclosed integrated waterproof and drainage system for a water-rich tunnel. The all-enclosed integrated waterproof and drainage system for the water-rich tunnel comprises a steel frame. A downcast pipe is arranged on the steel frame, one end of a connecting pipe is connected to one end of the downcast pipe, one end of a water collecting main pipe is connected to theother end of the connecting pipe, a vacuum pump is connected to one end of the water collecting main pipe, and the vacuum pump is connected to a water pump. According to the all-enclosed integrated waterproof and drainage system for the water-rich tunnel, the steel frame is arranged, the downcast pipe is arranged on the steel frame, one end of the connecting pipe is connected to one end of the downcast pipe, one side of the water collecting main pipe is connected to the other end of the connecting pipe, the vacuum pump is connected to one end of the water collecting main pipe, and the vacuum pump is connected to the water pump; and the structure is sturdy and durable, the drainage efficiency is improved, and the tunnel drainage is conveniently achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an all-inclusive integrated waterproof and drainage system for rich water tunnels. Background technique [0002] The tunnel drainage system is an important link in the process of tunnel construction, normal use and safe operation. Taking the railway tunnel as an example, the drainage system is directly related to the success or failure of the railway tunnel construction and the function of use. [0003] At present, cast-in-place concrete drainage systems are widely used in railway tunnels, which not only has the problems of low construction efficiency and difficult quality assurance, but also easily leads to blockage of drainage pipes during the pouring of concrete. In addition, after the drainage system is put into normal use, the concrete drainage ditches and concrete inspection wells poured on site are prone to cracking, causing water to enter the bottom of the tu...
