Bridge pier anti-collision and anti-scour facility based on construction temporary bridge and construction method
The invention relates to a bridge pier anti-collision and anti-scour facility based on a construction temporary bridge and a construction method. The bridge pier anti-collision and anti-scour facility comprises a sacrifice pile located on the upstream of a bridge pier in the downstream direction of water flow, a concrete platform fixed to the top of the sacrifice pile and lower than the normal water level, and a prefabricated straining beam fixed between the concrete platform and the bridge pier. The sacrifice pile comprises an outer pipe pile formed by a temporary bridge pile foundation and a miniature steel pipe pile located in the outer pipe pile, concrete is poured into the outer pipe pile and the miniature steel pipe pile, and the lower ends of the outer pipe pile and the miniature steel pipe pile are buried in a riverbed. The prefabricated straining beam comprises a central steel plate, an outer square steel sleeve and a hard material, the two ends of the central steel plate are connected with the concrete platform and the pier respectively, the central steel plate is sleeved with the outer square steel sleeve, and the hard material is located between the outer square steel sleeve and the central steel plate. And the temporary bridge pile foundation is arranged and constructed so as to be conveniently used by bridge anti-collision and anti-scouring structure facilities, and the construction cost is saved.
本发明涉及基于施工便桥的桥墩防撞和防冲刷设施及施工方法，包括位于大桥桥墩顺水流方向上游的牺牲桩、固定于牺牲桩顶部低于常水位的混凝土平台，及固定在混凝土平台与桥墩之间的预制系梁，所述牺牲桩包括由便桥桩基构成的外管桩及位于外管桩内的微型钢管桩，所述外管桩及微型钢管桩内灌注有混凝土且下端埋入河床内，所述预制系梁包括两端分别与混凝土平台和桥墩连接的中心钢板、套于中心钢板外部的外方钢套管及位于外方钢套管与中心钢板之间的硬质材料，桥梁防撞和防冲刷结构设施充分利用了施工便桥，按照永临结合的原则，布置施工便桥桩基，以便桥梁防撞和防冲刷结构设施使用，节约工程造价。
