摘　　要：沉管压舱水箱主要通过铺设PVC防水布进行防水密封,具体密封型式以及防水布结构尺寸受沉管及压舱水箱结构影响。深中通道工程沉管为国内首次采用钢壳混凝土组合结构,因此需要研究一种针对钢壳混凝土组合结构沉管的压舱水箱防水密封技术。本文结合深中通道沉管压舱水箱防水密封技术及实际应用对适用于钢壳混凝土组合结构沉管的压舱水箱防水密封型式进行研究说明,其优异的防水效果值得向类似工程推广。Ballast water tank of immersed tube is mainly sealed with PVC waterproof cloth.The detailed sealing type and the structural size of waterproof cloth are related to the structure of immersed tube and ballast water tank.Composite structure of steel shell and concrete is firstly used for immersed tube in Shenzhen-Zhongshan passage project in China.Therefore,it is necessary to develop a waterproof sealing technology for ballast water tank of the immersed tube made of steel shell-concrete composite structure.Based on the waterproof sealing technology for the ballast water tank of the immersed tube in Shenzhen-Zhongshan passage project and actual application,the waterproof sealing type of ballast water tank suitable for the steel shell-concrete immersed tube is studied and expounded.Its excellent waterproof effect is worthy of promotion in similar projects.
