[0006] 2. The existing methods for preventing water leakage fail to relieve and release the intercepted water, which will cause the intercepted water to accumulate in the protective layer for a long time. Utility Model Content

[0007] The utility model aims to solve the problems of aging of blocking materials and failure to discharge blocked water in time in the prior art, and proposes a device for preventing water leakage in mountain tunnel construction.

[0013] 1. The utility model provides a fixed layer inside the tunnel to provide preliminary support for the tunnel, and then a hydrophobic layer and a waterproof layer are provided inside the fixed layer. The hydrophobic layer can guide the leakage water well and can also separate the leakage water from the waterproof layer, thereby preventing the waterproof layer from being soaked in the leakage water for a long time and causing aging. Finally, an outer solid layer is provided outside the waterproof layer to strengthen the protection of the interior of the tunnel.

[0014] 2. The utility model has criss-crossed drainage grooves on the drainage plate, which can have a good guiding effect on the leakage water, and can use gravity to drain the leakage water in time.
