Problems solved by technology

[0004] The present invention aims at the technical defect that the maintenance of the existing tunnel siphon drainage system is difficult, and provides a tunnel drainage system and method that can be restored by reverse pressure water, which can repeatedly start the siphon during the use of the tunnel siphon drainage system, and solve the problems caused by the tunnel siphon drainage system. The problem of air accumulation in the siphon and the need to maintain and restart the siphon also solves the problem of sediment clogging in the siphon

Abstract

The invention provides a reverse water pressing recoverable tunnel drainage system. The reverse water pressing recoverable tunnel drainage system comprises a drill hole, a side ditch, a reverse waterpressing device and the like. The drill hole is formed in the position, needing drainage, in tunnel surrounding rock. The elevation of the top of a water tank is lower than the elevation of the bottomof the drill hole. The water tank is made of a transparent material. The reverse water pressing device is located on a roadbed slope outside a tunnel and comprises the water tank, an exhaust pipe, avalve A, a drainage pipe, a valve B, an gas bottle A, an gas bottle B, a flow guiding pipe, a branch pipe, a pressure gauge, an gas guiding pipe, a valve C, a one-way valve and the like. According tothe reverse water pressing recoverable tunnel drainage system, high-pressure gas is filled into the water tank for reverse water pressing so as to start siphoning, the problems of siphon air accumulation and silt plugging are solved, the reverse water pressing recoverable tunnel drainage system does not need help of other electrical equipment and is simple and reliable, materials are simple and easy to obtain, and the reverse water pressing recoverable tunnel drainage system is not disturbed by other external conditions and is wide in application range and suitable for wild mountain tunnels inremote areas.

Description

technical field [0001] The invention belongs to the field of tunnel engineering, and in particular relates to a tunnel drainage system and method which can be restored by reverse pressure water, and is especially suitable for drainage of surrounding rocks of mountain tunnels. Background technique [0002] Tunnel water leakage disease is a problem that plagues tunnel operation and maintenance. The long-term leakage of tunnel water will cause erosion and damage to the tunnel lining, and the leakage water will also have a softening effect on the surrounding rock of the tunnel, reducing the strength of the surrounding rock and causing the surrounding rock to become unstable and damaged. Tunnel seepage water dripping onto the road surface will cause water accumulation or ice on the road surface, affecting traffic operation. The current drainage measures have great damage to the integrity of the lining, the drainage range is small, the long-term effect is not good, and the mainte...
