Fabricated concrete hanging box cofferdam structure and construction method
The invention belongs to the technical field of deepwater bridge design and construction, and particularly relates to a fabricated concrete hanging box cofferdam structure and a construction method, the fabricated concrete hanging box cofferdam structure comprises a hanging box cofferdam formed by splicing side cofferdam modules and middle cofferdam modules, and a hoop arranged on the periphery of a steel casing in a sleeving manner; the middle cofferdam module and the side cofferdam modules are formed by splicing horizontal bottom plates with reserved pile foundation round holes and side wall plates perpendicular to the horizontal bottom plates, a gap is reserved between every two adjacent cofferdam modules, and the outer side faces of the gaps are temporarily bonded and sealed through waterproof materials and underwater sealant. The inner space of the gap is filled when bearing platform concrete is poured in the later period; the cofferdam module penetrates through a steel casing of the pile foundation through a reserved pile foundation round hole and is stood on a bracket; the reserved pile foundation round hole and the steel casing, the bottom face of the hoop and the upper surface of the horizontal bottom plate, and the hoop and the steel casing are connected in a sealed mode. According to the structure, the dependence on heavy hoisting equipment is solved, the construction is simple, and the fabricated construction is realized.
本发明属于深水桥梁设计施工技术领域，尤其涉及一种装配式混凝土吊箱围堰结构及施工方法，包括边围堰模块和中间围堰模块拼装而成的吊箱围堰、套设在钢护筒外周的抱箍；中间围堰模块、边围堰模块都是由预留桩基础圆孔的水平底板与垂直与水平底板设置的侧壁板拼接而成，相邻两围堰模块之间分别留有缝隙，缝隙外侧面通过不透水材料和水下密封胶临时粘合封闭，缝隙的内部空间在后期浇筑承台混凝土时一并填充；围堰模块通过预留桩基础圆孔穿过桩基础的钢护筒，并静置在牛腿上；预留桩基础圆孔与钢护筒之间、抱箍底面与水平底板上表面、抱箍与钢护筒之间密封连接。本发明的结构解决了对重型起吊设备的依赖性，施工简单，实现了装配式施工建造。
