Abstract
In the course of construction of Hong Kong-Zhuhai-Macao Bridge, many works were proceeded simultaneous, such as ballast water tanks and steel seal door removal and transshipment, ballast concrete pouring, site clearance, ventilation, lighting installation and so on. In this paper, we combined with the construction of the immersed tunnel to discuss the safety management, which can be a reference for similar projects.
Highlights
The Hong Kong-Zhuhai-Macao bridge immersed tunnel is the first offshore immersed tunnel built in China, the longest highway immersed tunnel and the only deep-buried immersed tunnel in the world
Safety management experience in immersed tube tunnel is discussed from seven aspects, including safety management, ventilation management, electricity management, fire control management, safety protection, monitoring and communication, and civilized construction, so as to provide reference for similar projects in the future
The tunnel of Hong Kong-Zhuhai-Macao Bridge is completed by immersed pipe docking, and each joint of the immersed pipes is connected with a rubber water stop
Summary
The Hong Kong-Zhuhai-Macao bridge immersed tunnel is the first offshore immersed tunnel built in China, the longest highway immersed tunnel and the only deep-buried immersed tunnel in the world. It realizes the conversion between bridge and tunnel, which is the most complicated and difficult part of bridge construction technology, and that is extremely challenging [1]. Safety management experience in immersed tube tunnel is discussed from seven aspects, including safety management, ventilation management, electricity management, fire control management, safety protection, monitoring and communication, and civilized construction, so as to provide reference for similar projects in the future
