Assembly type anti-explosion-impact pier protection device and installation method
The invention discloses an assembly type anti-explosion-impact pier protection device and an installation method, and belongs to the field of bridge structure disaster prevention. The device mainly comprises upper and lower connecting plates, inner and outer steel casings and a steel box chamber, wherein the steel box chamber is composed of a top plate, webs, U-shaped ribs and an inner-layer steelcasing; the steel box chamber is filled with a honeycomb tube core material, the honeycomb tubes are filled with filling sand, and the U-shaped ribs are filled with foam metal. According to the invention, the upper connecting plate, the lower connecting plate and the profile steel support are used for achieving annular and vertical assembly along the pier, the explosion impact energy can be effectively dispersed by utilizing a layered lattice structure formed by the inner and outer steel casings, the profile steel support, the steel box chamber and the honeycomb tube core material, and energycan be effectively dissipated through friction between sand and the large deformation capacity of foam metal. Meanwhile, the device is simple to manufacture, convenient to carry and rapid in assembly, partial replacement and repair can be achieved when damage occurs, and the device can be applied to land circular bridge pier studs with an anti-explosion-impact requirement.
本发明公开了一种装配式抗爆炸冲击作用的桥墩防护装置及安装方法，属于桥梁结构防灾领域；主要包括上下连接板、内外层钢护筒以及钢箱室；所述钢箱室由顶板、腹板、U型肋和内层钢护筒组成；所述钢箱室内部填充有蜂窝管芯材，蜂窝管中由填充砂填满，所述U型肋内部填充有泡沫金属；本发明利用上下连接板和型钢支撑实现沿桥墩环向及竖向的装配，利用内外钢护筒、型钢支撑、钢箱室、以及蜂窝管芯材构成的“层式格状结构”可有效分散爆炸冲击能量，采用砂之间的摩擦和泡沫金属的大变形能力可有效耗散能量，同时制作简单，搬运方便，组装快速，且在遭受破坏时可部分更换修复，本发明可应用于有抗爆炸冲击要求的陆上圆形桥梁墩柱。
