Full-prefabricated assembly type bridge construction platform and construction method
The invention belongs to the technical field of full-prefabricated assembly type bridge construction, and discloses a full-prefabricated assembly type bridge construction platform and construction method. The full-prefabricated assembly type bridge construction platform is provided with piles, temporary pile caps, connecting frames, cross beams, a platform plate and temporary railings; the temporary pile caps are connected to the piles, and the whole platform is supported by the connecting frames and the platform plate. The temporary pile caps are each provided with a connecting hole in the length direction, and the temporary pile caps are arranged at the upper ends of the piles in a sleeving mode through pin shafts arranged in the connecting holes in a penetrating mode. The cross beams are steel members formed by assembling and welding double-spliced I-shaped steel or H-shaped steel. Limiting grooves are formed in the cross beams, bearing truss girders are arranged in the limiting grooves, and polyfluortetraethylene plates are laid at the bottoms of the limiting grooves. By installing the detachable construction platform on the inserted and hit piles, parallel operation among all procedures in the construction process of a full-prefabricated bridge can be achieved, the full-prefabricated bridge can be moved and does not fall to the ground, meanwhile, a trestle and a shortcut do not need to be built around the bridge, and damage of construction operation to the original environment around the bridge is reduced.
本发明属于全预制装配式桥梁施工技术领域，公开了一种全预制装配式桥梁施工平台及施工方法，设置有桩柱、临时桩帽、连接架、横梁、平台板、临时栏杆，桩柱上连接临时桩帽，连接架与平台板支撑整个平台。所述临时桩帽沿长向设有连接孔，通过穿设于所述连接孔内的销轴将所述临时桩帽套设在所述桩柱的上端。横梁为双拼工字钢或H型钢组焊而成的钢构件。横梁上设置有限位槽，承重桁架梁设置在所述限位槽内，限位槽的底部铺设有聚四氟乙烯板。通过在已插打完毕的桩柱上安装可拆卸的施工平台，既能实现全预制装配式桥梁在施工过程中各工序间平行作业并且可移动不落地，同时无需在桥梁周围修建栈桥及便道，降低了施工作业对桥梁周围原始环境的破坏。
