Embodiment 1
[0026] Such as figure 1 , figure 2 As shown, the present embodiment provides a tunnel drainage system, which includes a borehole 1, a siphon 2, a side ditch 4, and a gas pressurized water device 3, and the borehole 1 and the siphon 2 are set at the position where drainage is required in the surrounding rock of the tunnel. The water inlet is placed in the borehole 1, and the water outlet of the siphon tube 2 is placed in an airtight water tank 31. The elevation of the top of the water tank 31 is lower than that of the bottom of the borehole 1. The water tank 31 is made of transparent material, and the gas pressure water device 3 is located in the On the subgrade slope 7 outside the tunnel, the gas pressurized water device 3 includes a water tank 31, an exhaust pipe 32, a valve A33, a drain pipe 34, a valve B35, a gas cylinder A81, a gas cylinder B82, a diversion pipe 83, a branch pipe 87, a pressure Table 84, air guide pipe 85, valve C86, water tank 31 is installed on the roa...

The invention provides a tunnel drainage system. According to the tunnel drainage system, the problems that the water leakage defect of a tunnel is a difficult problem disturbing tunnel operation andmaintenance, a tunnel lining is eroded and destroyed due to long-time water leakage of the tunnel, tunnel surrounding rock is also softened due to water leakage, the strength of the surrounding rock is reduced, and consequently the surrounding rock is destabilized and damaged are solved. The tunnel drainage system comprises a drill hole, a side ditch, a gas water pressing device and the like. High-pressure gas is filled into a water tank for reverse water pressing so as to start siphoning, the problems of siphon air accumulation and silt plugging are solved, the tunnel drainage system does notneed help of other electrical equipment and is simple and reliable, materials are simple and easy to obtain, and the tunnel drainage system is not disturbed by other external conditions and is wide in application range and suitable for wild mountain tunnels in remote 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, 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 maintenance cost is high.
