Bridge-head bumping prevention device and construction method
The invention discloses a bridgehead bumping prevention device and a construction method. The bridgehead bumping prevention device comprises a beam body arranged on a bridge abutment, a roadbed arranged corresponding to the bridge abutment, and a bridgehead bumping prevention mechanism arranged between the roadbed and the bridge abutment; the bridgehead bumping prevention mechanism comprises a retaining wall close to the roadbed and prevention parts arranged on the bridgehead and the roadbed; the prevention and treatment part comprises a transition slab arranged on the bridge abutment and the roadbed, a transition slab laminated cushion layer is arranged on the transition slab, the transition slab laminated cushion layer comprises a rubber layer and a carbon fiber plate layer, and a transition slab anti-disturbance device is arranged between the transition slab and the bridge abutment; according to the bridgehead bumping prevention device and the construction method, the problems that rainwater permeates into the lower portion of the transition slab, washes and erodes the roadbed, causes granular material loss, increases the water content of the roadbed and further causes frost heaving and thaw collapse of the roadbed can be solved, the rigidity of the roadbed is improved, meanwhile, the forming probability of bridgehead steps is reduced, and the construction period is shortened. And the problem of sudden rigidity change between a bridgehead rigid structure and a flexible road is better solved.
本发明公开一种桥头跳车防治装置及施工方法，包括桥台上设置有梁体，与桥台对应设置有路基，路基和桥台之间设置有桥头跳车防治机构；桥头跳车防治机构包括接近路基设置的挡墙和设置在桥头和路基上的防治部；防治部包括设置在桥台和路基上的搭板，搭板上设置有搭板层叠垫层，搭板层叠垫层包括橡胶层和碳纤维板层，搭板与桥台之间设置有搭板抗扰动装置；本发明公开的桥头跳车防治装置及施工方法，不仅可以解决雨水渗入搭板下方，对路基产生冲刷和侵蚀，造成粒料流失并增加路基含水量，进而使得路基出现冻胀、融沉现象的问题，在提高路基刚度的同时，降低了桥头台阶形成的几率，更好解决桥头刚性结构物与柔性道路之间刚度突变的问题。
