Construction method of steel caisson type shoreside pump house
The invention discloses a construction method of a steel caisson type shoreside pump house. The construction method comprises the following steps that a foundation bed is excavated underwater at the designed position of the pump house; the method comprises the following steps: prefabricating an overwater operation platform with a hollow middle by using steel buoyancy tanks The steel caisson is hoisted to the middle of the overwater operation platform; the side wall of the steel caisson is heightened at the upper part of the steel caisson; pump room bottom plate steel bars are bound in the box body, and bottom plate concrete and high wall plate guide wall concrete are poured; then the side wall of the steel box body is heightened to the designed height, then pump house side wall concrete is poured, and after a foundation is completed, the box body is transported to the designed position of the pump house in a floating mode and located; water is evenly injected into the box body, bottom sitting of the box body is completed, and then the box body is leveled; the wall of the high pump room is continuously connected to the box body, and the internal structure of the pump room is continuously constructed; and an upper structure and a subsequent structure of the pump house are constructed. According to the construction method of the steel caisson type shoreside pump house, the steel caisson serves as a construction cofferdam and a structural body concrete pouring formwork, a strong correlation effect is generated between the steel caisson and the structural body part, a traditional construction cofferdam is omitted, and the influence on flood discharge and navigation of an existing river channel can be reduced.
本发明公开了一种钢沉箱型式岸边泵房施工方法，包括以下步骤：在泵房设计位置的水下开挖基床；利用钢浮箱预制中间镂空的水上作业平台；将钢沉箱吊装至水上作业平台中间；在钢沉箱上部接高钢沉箱侧壁；在箱体内绑扎泵房底板钢筋，浇筑底板混凝土以及高墙板导墙混凝土；再接高钢箱体侧壁至设计高度，随后浇筑泵房侧墙混凝土，待基础完成后将箱体浮运至泵房设计位置，并进行定位；在箱体内均匀注水，完成箱体坐底，再将箱体整平；继续在箱体上接高泵房墙壁，继续进行泵房内部结构施工；进行泵房的上部结构和后续结构的施工。本发明公开的一种钢沉箱型式岸边泵房施工方法，钢沉箱兼做施工围堰和结构本体混凝土浇筑模板，与结构本体部分产生较强关联作用，且取消传统施工围堰，能够减小对现有河道行洪通航影响。
