摘　　要：沉管隧道作为现今跨海通道主要的结构形式,其管节接头的防水性和密闭性是至关重要的,直接影响工程全寿命的安全性和耐久性。OMEGA止水带为管节接头的第2道防水装置,其安装面空间狭窄,作业空间受限,和隧道内其他施工交叉影响较大。结合深中通道工程,文章详细介绍了大型钢壳沉管隧道受限空间OMEGA止水带安装施工技术,该技术具有施工简便、操作灵活、施工效率高、对其他工序影响较小等优点,可为后续沉管隧道、水下明挖隧道、地铁工程等管廊结构止水带安装提供借鉴及经验。Immersed tube tunnel is the main structural form of cross-sea channel,the waterproof and tightness of immersed tube joints are crucial,which directly affects the safety and durability of the whole life of the project.OMEGA waterstop is the second waterproof device of the tube joint,its installation surface space is narrow,the working space is limited,and it has significant cross impact with other construction in the tunnel.Combined with the Shenzhen-Zhongshan Link immersed tube tunnel engineering,this paper introduces the OMEGA waterstop installation and construction technology in confined space of large steel shell immersed tunnel.This technology has the advantages of simple construction,flexible operation,high construction efficiency,and low impact on other processes.It can provide reference and experience for the installation of waterstops in pipe gallery structures such as immersed tunnels,underwater open-cut tunnels,and metro projects in the future.
