含地下、地表水较为丰富的隧道和明峒,常因施工期间对引排水的重视处理不当,或防水层制作不良,当混凝土衬砌形成后,岩石裂隙水和地表渗透水以润水、滴水、股水等不同形式沿混凝土表面薄弱部位或施工缝流出,严重地影响着工程质量和电气化铁路的架设。为了解决隧峒漏水,一般依赖压浆。但实践告诉人们,单凭压浆不能彻底解决漏水问
The underground tunnels and the open water with abundant surface water are often improperly handled due to drainage and drainage during the construction period or the waterproofing layer is poorly prepared. When the concrete lining is formed, the fissure water and the surface seepage water in the rock are flooded and dripped, Different forms of stock water flow out along the weak parts of the concrete surface or construction joints, seriously affecting the quality of the project and the erection of the electrified railway. In order to solve the tunnel leakage, generally rely on grouting. However, practice tells people that pressure grouting alone can not completely solve the problem of water leakage
