磁器口水下明挖隧道防水技术研讨

Brief Introduction to Waterproofing Technology for Open-cut Underwater Tunnel at Ciqikou

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。

With reference to the advanced waterproofing experience of underwater tunnel in China and, based on the waterproofing design for underwater 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.
