摘要
港珠澳大桥岛隧工程预制沉管结构尺寸和埋置深度大,为满足隧道预制、安装施工和使用的要求,设置了数量众多的预埋件,按预埋件的功能可分为结构受力、止水、安装辅助。沉管预制中大部分预埋件主要作用是防水,为了保证工程质量,必须严格控制其精度。文章主要介绍港珠澳大桥沉管预制中大型预埋件精确安装技术,包括端钢壳、OMEGA、中埋式止水带等。经工程实践,该技术可靠有效。
The prefabricated immersed tube of Hongkong-Zhuhai-Macao Bridge island and tunnel project has large structure size and great embedment depth, a large number of embedded parts are set up to meet the requirements of prefabrication, installation and use of the tunnel, the embedded parts are classified as force, water stop, auxiliary installation according to their functions. The major role of most embedded parts in prefabrication of immersed tube is waterproof, their accuracy must be controlled strictly in order to ensure the construction quality. This paper introduced the precision installation technology of large embedded parts in prefabricated immersed tube of the Hongkong-Zhuhai-Macao Bridge, including the end steel shell, OMEGA, buried water stop, and so on. The engineering practices prove that the technology is reliable and effective.
