Device for preventing bumping at bridge head and method

Abstract

The invention relates to a device for preventing bumping at bridge head. The device comprises an elastic caterpillar track arranged on roadbed and bridge base; a track surface of the elastic caterpillar track is horizontal; two ends of the elastic caterpillar track are respectively integrated with the roadbed and the bridge base; a buffer support is arranged on a lower track surface of the elasticcaterpillar track; a hydraulic buffer cylinder is served as the buffer support and a piston rod is vertically arranged; the upper end of the piston rod of the buffer support is resisted against the elastic caterpillar track. A traditional back-wall pavement is replaced with the elastic caterpillar track, so that the phenomenon of bumping at bridge head can be avoided; the elastic caterpillar track is fixed on the buffer support; the buffer support can be conveniently detached; the device for preventing bumping at bridge head is capable of effectively realizing the rigid and soft transition ofabutment surface, expansion joint and pavement and is capable of achieving the purpose of preventing bumping.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a device and method for preventing vehicle jumping at the bridge head. Background technique [0002] There are different degrees of settlement fractures at the backfill of the joint platform between the road surface and the bridge (the settlement value is generally 10-30cm, and some even exceed 60cm), which makes vehicles jump and impact when passing, thereby causing additional impact loads on the bridge and road surface , so that the driver and passengers feel bumpy and uncomfortable, and even cause the vehicle to slow down significantly, which can lead to serious traffic accidents (especially vehicle mechanical accidents). Therefore, the problem of vehicle jumping at the bridge head has become an important factor affecting the engineering quality and cost of high-grade highways. The problem of vehicle jumping at the bridge head has always been one of the problems that p...

AI Technical Summary

Problems solved by technology

Under the action of vehicle load, structural self-weight, and natural factors, the bridge and the road settle at the same time, but the settlement of the two is very different. The settlement of the road is much larger than the settlement of the bridge, forming a staggered platform, resulting in a bridge head when driving. Jump;
