The waterproof requirements of the railway tunnel are from no water dripping at the arch part of the lining of the early electrified railway tunnel to line up, no water dripping at the side wall, to no seepage, no leakage and no crack of the existing tunnel lining, and the waterproof requirements of the railway tunnel put forward high requirements on the design of tunnel waterproof and drainage, the construction process and the quality control.
In order to prevent water leakage of the tunnel, each tunnel project adopts water prevention and drainage measures, but a considerable number of tunnel projects have serious water leakage problems in the near future of operation. Engineering practice shows that: the longitudinal and circumferential construction joints and deformation joints of the tunnel structure are the frequent parts of water leakage. The reason is that the existing waterproof construction joints and deformation joints are not enough: the installation quality of the traditional buried water stop belt is not easy to guarantee, and the back-attached water stop belt cannot be compacted around the top of the tunnel; the technical defects cause construction difficulty, so that the perfect design concept cannot be really implemented.
