隧道渗漏一直是地下防水工程的棘手问题。采用新材料、新工艺、新设备、新技术对提高隧道防水效果起着关键性的作用。介绍了上海轨交某隧道工程防水材料的优化,对其断面构造形式、材质、性能指标及施工要求进行了修改,取得了良好的效果,可供提高隧道防水施工质量时借鉴。
Tunnel leakage has always been a thorny problem in underground waterproofing projects. The use of new materials, new processes, new equipment, new technologies to improve the tunnel waterproofing plays a key role. This paper introduces the optimization of the waterproof material in a tunnel project of Shanghai Rail Crossing, and modifies the structure, material, performance index and construction requirements of the cross section of the tunnel in Shanghai. The results have achieved good results and can be used for reference when improving the quality of tunnel waterproofing construction.
