Box-type water filling cofferdam structure and installation and disassembly construction method
The invention provides a box-type water filling cofferdam structure and an installation and disassembly construction method. The cofferdam structure comprises a box-type structure composed of steel pipes and steel plates. According to the cofferdam structure, a steel pipe frame and the steel plates are adopted to meet the requirements of a body type and structural stress of a cofferdam, a flap valve is arranged to control the amount of water in the box-type cofferdam, the overall weight of the cofferdam is controlled, the problems of bottom water stopping, overall stability and hoisting are solved, inflation water stop bags are arranged at the two ends of the cofferdam, the problems of lateral water leakage of the cofferdam and conformability during repeated installation are solved, in combination with structural characteristics, the feasible construction method is provided, and the feasibility and reliability of the cofferdam structure are guaranteed, so that the cofferdam structure design and construction problems of municipal box culvert desilting in rainy seasons and reconstruction construction under the condition that the water retaining depth is smaller than 3.0 m are solved.
本发明提供了一种箱式充水围堰结构及安装和拆除施工方法，该围堰结构包括以钢管和钢板组成的箱式结构。本发明采用钢管框架+钢板来满足围堰的体型及结构受力要求；通过设置拍门来控制箱式围堰内水量，从而控制围堰整体重量，解决底部止水、整体稳定、吊装问题；通过在围堰两端设有充气止水袋，来解决围堰侧向漏水和反复安装时的适形问题。结合上述结构特点，提出了切实可行的施工方法，保证了围堰结构的可实施性和可靠性。解决了市政箱涵雨季清淤、改造施工，挡水水深小于3.0m条件下的围堰结构设计及施工问题。
