Semi-prefabricated construction method for large deepwater caisson shallow dock
The invention relates to a semi-prefabricated construction method for a large deepwater caisson shallow dock, which comprises the following steps of: pouring caisson bottom plate concrete in a dry dock, mounting a prefabricated plate and a steel truss around the bottom plate to form an open box body structure, then hauling the box body to a bridge site, finishing caisson construction on water by adopting a concrete cast-in-place mode, and finally injecting water into the caisson to sink in place. The requirement for the excavation depth of the dry dock can be greatly reduced, the dredging workload of the undocked floating transportation channel is reduced, and therefore the construction cost is reduced, and meanwhile the construction period of the caisson can be shortened.
本发明涉及一种大型深水沉箱浅船坞半预制施工方法，在干船坞内浇筑沉箱底板混凝土，在底板周围安装预制板和钢桁架，形成一敞口箱体结构，然后将箱体拖运至桥位，在水上采用混凝土现浇方式完成沉箱施工，最后将沉箱注水下沉就位。本发明可大幅降低干船坞的开挖深度要求，减小出坞浮运航道的疏浚工作量，从而降低施工成本，同时有利于缩短沉箱建造工期。
