Semi-floating state pouring method for steel shell concrete immersed tube
The invention relates to the technical field of steel shell concrete immersed tube tunnel construction, and discloses an immersed tube concrete semi-floating state pouring method. The method comprises the following steps of assembling or totally splicing an immersed tube total steel shell structure in a dry dock; carrying out concrete pouring on bottom plate partition bins and all or part of wall partition bins of an immersed tube in the dock; conveying the immersed tube subjected to partial concrete pouring in the dock to an overwater floating state pouring station in a floating manner; and conducting concrete pouring on the remaining parts of wall partition bins, and top plate partition bins of the immersed tube at the floating state pouring station. Immersed tube concrete pouring uses a mode of combining partial pouring in a dry dock land area construction field and secondary pouring on water, so that the requirements on dock bottom bearing capacity, floating transportation channel water depth scale and dry dock bottom elevation are reduced; and compared with a whole-course dry dock pouring mode, the service cycle of the dry dock is shortened, the overall construction period of immersed tube pouring and transportation is shortened, the temporary engineering dredging amount is reduced, the engineering cost is reduced, and environmental protection is facilitated.
本发明涉及钢壳混凝土沉管隧道施工技术领域，公开了一种沉管混凝土半浮态浇筑方法，包括以下步骤：在干坞内进行沉管总体钢壳结构组装或总拼；在坞内进行沉管底板隔仓、全部或部分墙体隔仓混凝土浇筑；将在坞内完成部分混凝土浇筑的沉管浮运至水上浮态浇筑工位；在浮态浇筑工位进行沉管剩余墙体隔舱、顶板隔舱混凝土浇筑。沉管混凝土浇筑采用在干坞陆域施工场内进行部分浇筑和在水上进行第二次浇筑结合的方式，降低了对坞底承载力、浮运航道水深尺度及干坞底标高的要求；与全程干坞浇筑的方式相比既缩短了干坞的使用周期，更缩短了沉管浇筑和运输的整体工期，又减少了临时工程疏浚量，降低了工程造价，有利于环境保护。
