Fabricated pier anti-collision buffering device and construction method thereof
The invention relates to a fabricated pier anti-collision buffering device and a construction method thereof.The device comprises a base and a bearing frame, the base comprises at least three steel pipe cast-in-place piles, the distance between the top face of concrete in the steel pipe cast-in-place piles and the pile top is 2-3 m, the bearing frame comprises vertical rods corresponding to the steel pipe cast-in-place piles in number, and the vertical rods are inserted into the steel pipe cast-in-place piles; a plurality of rubber particles are arranged between the vertical rods and the steel pipe cast-in-place pile, each vertical rod is provided with an energy dissipation box, each energy dissipation box comprises a movable plate and a shell, the movable plates and the shells are connected through a plurality of springs, and the shells are connected to the tops of the vertical rods through energy dissipation rings. The base goes deep into the ground and is not prone to damage, the bearing frame and the energy dissipation box can be prefabricated in a factory and rapidly assembled on site, a multi-stage energy dissipation system is formed, the first stage consumes energy through spring deformation in the energy dissipation box, and the second stage consumes energy through plastic deformation of the energy dissipation ring. In the third stage, a bearing frame is used for extruding rubber particles to deform to consume a large amount of energy, and falling stone impact can be effectively resisted.
本发明关于一种装配式桥墩防碰撞缓冲装置及其施工方法，该装置包括基座和承载架，基座包括至少三个钢管灌注桩，钢管灌注桩内的混凝土顶面距离桩顶2m‑3m，承载架包括与钢管灌注桩数量对应的竖杆，竖杆插入钢管灌注桩，竖杆和钢管灌注桩之间具有若干橡胶粒，每个竖杆上设置消能盒，消能盒包括活动板和壳体，活动板和壳体通过若干弹簧连接，壳体通过消能环连接于竖杆顶部。本发明的基座深入地下不易破坏，承载架和消能盒能够工厂预制，现场快速装配，并且形成多级消能体系，第一级利用消能盒内的弹簧变形来消耗能量，第二级利用消能环的塑性变形来消耗能量，第三级利用承载架挤压橡胶粒变形来消耗大量能量，能够有效抵御落石冲击。
