摘要
港珠澳大桥岛隧工程的防水设计方案是以沉管混凝土结构的自防水为基础,根据小节管缝以及水泥混凝土施工缝的不同,主防水层分别采用双层和单层SBS改性沥青防水卷材,由卷材防水层和非固化复合形成一个防水、抗拉伸、耐振变相结合的防水系统,保证了防水工程是一个连续密闭的体系。
The waterproofing design of Hong Kong-Zhuhai-Macao Bridge Island Tunnel Project is based on self-waterproofing of immersed concrete structure. According to the different joints and cement concrete joints, the main waterproofing layer is double-layered and single-layer SBS modified asphalt waterproofing membrane. The waterproofing system is formed by waterproofing membrane and non-curing waterproofing coating, which is stretch-resistant and vibrationresistant. The composite waterproofing system ensures the waterproofing project to be a continuous closed system.
