The invention relates to the technical field of road and bridge construction, and discloses a combined cofferdam structure. The combined cofferdam structure comprises steel sheet piles, the steel sheet piles are arranged to form a water retaining structure, a first filling area is arranged on the downstream face of the water retaining structure, a first filling body is arranged in the first filling area, filling stones are arranged at the bottom of the first filling body, and filling clay is arranged in the middle of the first filling body. A hardened concrete layer is arranged on the upper portion of the filling clay. The cofferdam is simple in structural form and convenient for on-site actual operation, the hardened concrete layer can play a role in stabilizing the cofferdam, a construction vehicle running channel is formed, various construction vehicles can be conveniently transported to a construction site, the construction progress is accelerated, and the construction cost is greatly reduced; according to the cofferdam, the adverse situation that the upstream face of the cofferdam is scoured after the water level rises in the wet season is avoided, and the safety risk of downstream face construction is reduced.
本发明涉及道路桥梁施工技术领域，公开了一种组合围堰结构。本发明公开的组合围堰结构，包括钢板桩，所述钢板桩排列形成挡水结构，所述挡水结构的背水面设置有第一填充区，所述第一填充区设置有第一填充体，所述第一填充体的底部设置有填充石，所述第一填充体的的中部设置有填充粘土，所述填充粘土的上部设置有硬化混凝土层。本申请结构形式简单，便于现场实际操作，硬化混凝土层不但可以起到稳定围堰的作用，而且形成施工车辆行驶通道，便于各类采用运输至施工点，加快施工进度，大幅度降低施工成本，围堰保证了丰水季水位上涨后对围堰的迎水面冲刷带来的不利情况，降低了对背水面施工的安全风险。
