Problems solved by technology

[0002] When the tunnel open hole is located in the high water level stratum, the existing waterproof and drainage system still cannot effectively avoid tunnel diseases such as structural uplift, lining water leakage, tunnel bottom heaving, mud turning and so on.
In particular, the open tunnel structure is mostly located at the entrance section of the tunnel. The back ring of the open tunnel lining at the entrance section in the cold region, the vertical drainage blind pipe and the double-sided gutters are easy to freeze, causing the tunnel drainage system to fail, and the water cannot be discharged in time. The tunnel lining swells due to freezing. The problem of disease is becoming more and more prominent

Abstract

The invention relates to the technical field of railway tunnel construction, in particular to an open cut tunnel waterproof and drainage system. The system involves a tunnel wall and a tunnel invertedarch, a central drainage pipe is arranged below the tunnel inverted arch, longitudinal drainage pipes are arranged on the two sides of the tunnel wall and arranged in the tunnel direction, multiple water permeable holes are formed in the upper portions of the longitudinal drainage pipes, and the longitudinal drainage pipes are connected with the central drainage pipe through transverse drainage pipes. According to the system, the back drainage capacity of an open cut tunnel lining can be enhanced, underground water is effectively drained, the water load around the tunnel lining is reduced, meanwhile, the anti-floating and cold-proof effects are achieved, the waterproof and drainage problems of the tunnel open cut tunnel lining in a high-water-level stratum in a cold region are solved, andthe freezing damage to the tunnel open cut tunnel is effectively reduced.
