香港沙中线沉管管节双驳船骑吊沉放施工技术

Construction Technology of Double Barges Floating Pontoon for Lifting and Installation of Immersed Tunnel Element

在沉管隧道施工应用的历史中,管节沉放所使用的方法和设备种类繁多,管节沉放的精确安装是修建沉管隧道的重要一环,涉及对作业窗口期的选择、设备性能的选取、技术人员对设备的操控和管节沉放过程中的动态监测等诸多环节。主要介绍使用双驳船骑吊沉放对接安装沉管管节的施工方法。

In the history of the immersed tunnel development,there are a lot of methods and equipments applied in the elements sinking and installation. The accurate installation of the slements is a critical point in the construction of immersd tunnel,which involves the selection of equipment selection of operation window,the manipulation of the equipment by technicians,and the dynamic monitoring during tube sinking. This paper introduces the method of lifting and installation of immersed tunnel element with double barges floating pontoon.
