Integrated prefabricated concrete cofferdam structure for deepwater bearing platform and construction method
The invention discloses an integrated prefabricated concrete cofferdam structure for a deepwater bearing platform, and belongs to the technical field of deepwater bridge bearing platform construction, the integrated prefabricated concrete cofferdam structure comprises a box body, a water stop belt and a supporting hoop, the box body is of a high-strength glass fiber fine stone reinforced concrete thin plate structure, the supporting hoop is arranged on a pile foundation, the pile foundation is sleeved with the box body, and the box body is placed on the supporting hoop; the water stop belt is arranged between the box body and the pile foundation; the inner bottom and the inner wall of the box body are both provided with internal lap joint reinforcing bars poured together with the bearing platform. The box further comprises a reinforcing steel sleeve with an axial opening, the reinforcing steel sleeve is detachably connected with the box body through a connecting bolt, and the reinforcing steel sleeve is provided with a lifting piece used for hanging a lifting rope. The problem of water sealing in deepwater bearing platform construction is solved, a good closed environment is provided for a bearing platform straining beam, meanwhile, the high-strength concrete shell is designed and directly serves as a protection device of the bearing platform without being detached, and the corrosion resistance of an underwater concrete structure is improved. The invention further provides a construction method of the integrated prefabricated concrete cofferdam structure for the deepwater bearing platform.
本发明公开了一种深水承台用一体式预制混凝土围堰结构，属于深水桥梁承台施工技术领域，包括箱体、止水带和支撑抱箍，箱体为高强玻纤维细石钢筋混凝土薄板结构，支撑抱箍设置在桩基上，箱体套装于桩基并搁置于支撑抱箍上，止水带设于箱体与桩基之间；箱体的内底及内壁上均设置有与承台一起浇筑的内部搭接配筋；还包括具有轴向敞口的加固钢套，加固钢套通过连接螺栓与箱体拆卸地连接，加固钢套上设有用于挂设吊装绳的吊件。本发明解决了深水承台施工封水问题，为承台系梁提供了良好的封闭环境，同时，高强度混凝土壳体的设计，不拆除直接作为承台的保护装置，提高了水中混凝土结构抗腐蚀性能。本发明还提供一种深水承台用一体式预制混凝土围堰结构的施工方法。
