Tunnel lining leakage water diversion and drainage mechanism with compensation function and using method thereof

Abstract

The invention discloses a tunnel lining leakage water diversion and drainage mechanism with a compensation function and a using method thereof. The mechanism solves the problem of low guide and drainage capacity of a diversion and drainage pipeline in the prior art and has the advantages that the diversion and drainage capacity of the diversion and drainage pipeline can be increased and the driving safety of a tunnel is ensured. According to the scheme, the tunnel lining leakage water diversion and drainage mechanism comprises a water receiving part arranged on the inner wall of a tunnel lining, the water receiving part is communicated with a longitudinal diversion and drainage pipe, the longitudinal diversion and drainage pipe is arranged in the length direction of a tunnel maintenance channel, the longitudinal diversion and drainage pipe is provided with a compensation diversion and drainage pipe, the compensation diversion and drainage pipe is provided with a switch valve, and the compensation diversion and drainage pipe can rotate relative to the longitudinal diversion and drainage pipe.

Description

technical field [0001] The invention relates to the field of tunnels, in particular to a tunnel lining leakage water diversion and drainage mechanism with a compensation function and a use method. Background technique [0002] Drainage of tunnel lining leakage water is the key content of tunnel disease treatment. Whether the leakage water can be timely and completely drained out of the tunnel is often the key link to determine the success of tunnel disease treatment, but it is limited to lining sections, building boundaries, and avoidance of electromechanical equipment, etc. Factors, the space that the tunnel can be used for lining leakage water drainage is often very limited, which has a great impact on the leakage water drainage project, and is even difficult to implement. [0003] In view of the above-mentioned difficulties in the layout of tunnel drainage pipes, currently tunnels often set up a longitudinal pipeline along the top surface of the cable trench (maintenance ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a tunnel lining leakage drainage mechanism with compensation function, which can effectively collect leakage water, and can automatically start when the flow capacity of the longitudinal drainage pipe is insufficient. The compensation drainage pipe with increased flow capacity ensures that the seepage water in the tunnel is timely and completely drained out of the tunnel without affecting the passage of the tunnel, so as to ensure the safety of the tunnel structure and operation
