摘要
港珠澳大桥岛隧工程隧道基槽已安装管节钢封门前清淤,主要为邻近管节碎石垫层铺设前及碎石垫层面的清淤施工。在该区域附近清淤施工,如操作不当或预案不足将会给已安隧道沉管带来不可接受的风险,因此有必要对在该区域清淤施工的相关细节进行充分研究。通过采取风险防范措施,取得了较好的施工效果。
The silt removal in front of the steel door of installed immersed tunnel tube In the Hongkong-Zhuhai-Macao Bridge Island & Tunnel project is executed before laying of the gravel bedding layer for the adjacent tunnel section and desilting on the suface of gravel bedding layer. While desilting in the mentioned areas, unacceptable risk will be caused to the foundation trench for immersed tunnel sections by improper operation or insufficient precautionary measures, therefore it is necessary to study full details of desilting. By taking the risk prevention measures, to achieve better construction effect.
