磁器口水下明挖隧道防水技术研讨

摘要

With reference to the advanced waterproofing experience of underwater tunnel in China and, based on the waterproofing design for underwa-ter tunnel at Ciqikou, the waterproofing technology adopted is introduced from the aspects of concrete self-waterproofing, joint waterproofing, flexible waterproof layer and later poured band and others. Combined with specifications for Design of Highway Underwater Tunnel(D71-2014 JTG), some new materials and waterproof technologies presented in the practical application are discussed for reference.%该文通过参考国内先进的水下隧道防水经验,以磁器口水下隧道防水设计为工程背景,从混凝土自防水、接缝防水、柔性防水层及后浇带防水等环节介绍了该隧道防水技术.并结合《公路水下隧道设计规范》(JTG D71-2014),对规范提出的一些新材料及防水工艺技术的实际应用进行探讨,隧道工作人员遇到类似工程设计时可作参考.
