摘要
沉箱结构的坞门在沉管隧道预制场中是重要的构件,其尺寸达到了59 m×25.2 m×29.1 m。虽然沉箱施工在水工行业已较为普遍,但大型化需浮运的沉箱施工有其特点。从港珠澳大桥沉管预制厂大型化沉箱模板的设计和施工入手,对特别需要注意的方面进行探讨,得到一些有益的经验。
Caisson type dock gate is an important part of the immersed tunnel precast yard. lts size is 59 m×25.2 m×29.1 m. Although the construction of caisson is very common in hydraulic industry, the construction of large-scale caisson in need of floating transportation has its characteristics. Starting with the design and construction in formwork of large-scale caisson type dock gate, which is in the immersed tube prefabricated factory of the Hongkong-Zhuhai-Maeao Bridge, we discussed some parts which in need of particular attention to. The henefieial experiences are obtained.
