Modular concrete cofferdam and construction method
The invention belongs to the technical field of bridge foundation construction enclosure, and particularly relates to a modular concrete cofferdam and a construction method. The concrete cofferdam comprises a bottom plate, the bottom plate is of a double-layer plate structure and comprises a prefabricated plate and a cast-in-place plate, the prefabricated plate is of a modular structure and comprises a plurality of prefabricated plate fragments, a bottom plate wet joint is arranged between every two adjacent prefabricated plate fragments, a wall plate is fixedly arranged on the outer edge of the edge of the bottom plate, and the wall plate is of a modular structure and comprises a plurality of wall plate fragments; the side faces of the multiple wall plate fragments are connected end to end, a wall plate wet joint is arranged between every two adjacent wall plate fragments, and the bottom plate wet joints and the wall plate wet joints are formed by pouring micro-expansion concrete. The whole cofferdam is composed of the prefabricated reinforced concrete bottom plate, the wall plates and the diagonal draw bars, the wall plates are one part of the bearing platform, a permanent structure and a temporary structure are combined, and compared with a traditional reinforced concrete cofferdam, a large amount of temporary material input can be saved, the construction cost is reduced, and environment protection is facilitated.
本发明属于桥梁基础施工围护技术领域，特别涉及一种模块化混凝土围堰及施工方法。该混凝土围堰包括底板，底板为双层板结构，包括预制板和现浇板，预制板为模块化结构，包括多个预制板分片，两个相邻预制板分片之间设有底板湿接缝，底板边缘外沿固定设有壁板，壁板为模块化结构，包括多个壁板分片，多个壁板分片侧面首尾相连，相邻两个壁板分片之间设有壁板湿接缝，底板湿接缝和壁板湿接缝均由微膨胀混凝土浇筑而成。本发明通过预制钢筋混凝土底板、壁板及斜拉杆组成整体围堰，其中壁板是承台的一部分，做到永久结构与临时结构相结合，相较于传统的钢筋混凝土围堰可以节省大量的临时材料投入，降低施工成本，有利于环境的保护。
