摘　　要：南宁市金良路综合管廊采用现浇钢筋混凝土廊体结构,在防水设计上,该项目针对广西地区多雨且地下水丰富、廊体之间存在大量环向变形缝等影响因素,柔性防水采用CPS-CL反应粘湿铺防水卷材与CPS节点密封膏配合设防,与结构自防水形成刚柔并济的全密封防水体系。本文在详细介绍廊体底板、侧墙、顶板防水施工的基础上,对变形缝、穿墙套管等细部节点的防水做法作了重点阐述。Cast-in-place reinforced concrete is adopted for the structure of the utility tunnel of Jinliang Road in Nanning.Considering the plenty of rain and underwater in Guangxi region,lots of circular deformation joints between the tunnel bodies and other influence factors,the combination of CPS-CL reaction sticky wet laid waterproofing membrane and the CPS detail sealant is used for flexible waterproofing,and it forms a comprehensive waterproofing system together with structure self-waterproofing.Apart from a detailed introduction of the waterproofing construction for tunnel floor,side wall and ceiling,the article mainly focuses on waterproofing practices for details such as deformation joint,wall-through pipes etc.
