Concrete wet connection swivel supporting foot prefabricated assembly bearing platform and construction method
The invention discloses a concrete wet connection swivel supporting foot prefabricated assembly bearing platform and a construction method, the concrete wet connection swivel supporting foot prefabricated assembly bearing platform comprises an upper bearing platform, a lower bearing platform, an upper spherical hinge, a lower spherical hinge and a supporting foot prefabricated part, and concrete is filled between the upper bearing platform and the lower bearing platform; the supporting leg prefabricated part is composed of a steel pipe, a concrete column body poured into the steel pipe and a prefabricated concrete block wrapping the outer side of the steel pipe. The construction method comprises the construction steps of (1) spherical hinge manufacturing, (2) supporting foot prefabricated part manufacturing, (3) lower bearing platform construction and lower spherical hinge installation, (4) supporting foot prefabricated part installation, (5) upper bearing platform construction and upper spherical hinge installation, (6) pier and main beam construction, (7) bridge rotation and (8) sealing plate concrete pouring. The method has the advantages that stress is reasonable, strength is high, construction is convenient, the supporting feet and the spherical hinge upper rotating disc are connected into a whole through prefabricated concrete and interface connecting steel bars, the problem that the connecting strength of disc sealing concrete and the supporting feet is not enough can be effectively solved, the integrity of a steel-concrete composite structure is fully guaranteed, and development and popularization of a rotating construction method are facilitated.
本发明公开了一种混凝土湿接连接的转体撑脚预制装配承台及施工方法，包括上承台、下承台、上球铰、下球铰、撑脚预制构件、上下承台间填充混凝土，撑脚预制构件由钢管、灌注在钢管内部的混凝土柱体和包裹在钢管外侧的预制混凝土块组成。施工步骤包括：①球铰制作，②撑脚预制构件制作，③下承台施工及下球铰安装，④撑脚预制构件安装，⑤上承台施工及上球铰安装，⑥桥墩与主梁施工，⑦桥梁转体，⑧封盘混凝土浇筑。本发明优点在于：受力合理、强度高、施工便利，利用预制混凝土及界面连接钢筋将撑脚及球铰上转盘连成整体，可有效避免封盘混凝土与撑脚连接强度不够的问题，充分保证了钢混组合结构的整体性，有利于转体施工方法的发展与推广。
