Bridge pier anti-collision fender
The invention discloses a bridge pier anti-collision fender which is characterized in that an anti-collision fender body is made of a material with the strength obviously improved along with temperature reduction, a supercritical fluid pipeline is arranged in a dangerous area of the anti-collision fender body, and the supercritical fluid pipeline is filled with supercritical fluid; when the dangerous area of the anti-collision fender body is subjected to high-strength collision exceeding a certain threshold value, a supercritical fluid pipeline is broken, supercritical fluid overflows, and the surrounding environment is rapidly cooled due to sudden pressure reduction and phase change heat absorption, so that the strength of the anti-collision fender body in the dangerous area is remarkably improved. The material characteristics of the anti-collision fender body and the supercritical fluid are combined and utilized, the strength of the anti-collision fender body in a dangerous area can be remarkably improved during high-strength collision, and the anti-collision performance is improved.
本发明公开了一种桥梁桥墩防撞护舷，防撞护舷主体采用强度随温度降低而显著提高的材料，防撞护舷主体的危险区域内布设有超临界流体管道，超临界流体管道内填充有超临界流体；防撞护舷主体的危险区域受到超过一定阈值的高强度撞击时，超临界流体管道破裂，超临界流体溢出，因压力突然降低，发生相变吸热，使周围环境快速降温，从而显著提高防撞护舷主体在危险区域的强度。本发明结合并利用了防撞护舷主体和超临界流体的材料特性，在高强度撞击时能显著提高防撞护舷主体在危险区域的强度，提高了防撞性能。
