With the continuous innovation and development of tunnel construction technology, tunnel waterproof materials and the process thereof have great progress. The mine method tunnel is characterized in that a water-proof principle of 'mainly discharging and preventing discharging combined' is adopted in construction on the premise of not influencing greening vegetation of mountains because of large water pressure and large water quantity of mountains and cracks. The railway and highway mine tunnel built in China all adopt composite lining, namely a plastic waterproof board is arranged between a spray anchor support layer and a concrete secondary lining to serve as a waterproof layer.
The existing waterproof layer is arranged in the following mode: the waterproof layer is composed of a buffer layer and a waterproof layer, when the buffer layer (geotextile) and the waterproof layer are combined together, the elongation percentage (generally 20-100%) of the geotextile limits the elongation percentage (500%) of the waterproof layer, so a distributed method is generally adopted in waterproof layer construction, namely, a hot-melt liner and the geotextile are fixed on sprayed concrete by using a shooting nail, the hot-melt liner is distributed in a plum blossom shape, and then an electric hot pressure welder or an ultrasonic welder is used for firmly welding the waterproof board and the hot-melt liner in a corresponding hot-melt mode. This waterproof construction has the following drawback: because the tunnel has the radian, and in the aerial work, lay the scene and hold the welding ware intensity of labour great for a long time, and weld overheated and cause the waterproof board scald easily, the waterproof board of not enough welding is thrown off easily, and waterproof quality is difficult to guarantee.
