Bridgehead structure for preventing bumping
In the construction and operation process of a high-grade highway, due to differential settlement, sudden rigidity change, the vehicle speed, the vibration resistance of a vehicle and the like of thehighway and a bridgehead approach road, the vehicle jumps when passing through the highway and the bridgehead approach road, and the phenomenon is called bridgehead vehicle jumping. Damage of bumpingat the bridgehead is large, driving comfort and driving safety are affected, driving speed is reduced, vehicle operation cost is increased, and diseases of bridges and road surfaces are accelerated. The invention provides a bridgehead structure for preventing bumping, a butt strap with a hinge structure is additionally arranged between a main bridge and a bridgehead approach, the butt strap has aspecial transition shape, a hinge is used for connecting the bridge body and the butt strap, the main bridge and the bridgehead approach are connected, the fall of bumping at the bridgehead is buffered, and the bumping problem is thoroughly solved.
在高等级公路的建设和运营过程中，由于公路和桥头引道处的不均匀沉降、刚度突变和车速与车辆本身的抗振性能等原因引起车辆通过时产生跳跃，这种现象称为桥头跳车。桥头跳车的危害很大，影响行车舒适度及行车安全、降低行车速度、增加车辆运营费用、加速桥梁及路面的病害等。本发明提出一种防治跳车的桥头结构，通过在主桥与桥头引道的之间增加一块具有铰链结构搭板，其中搭板具有特殊的过渡形状，铰链用以连接桥体与搭板，将主桥与桥头引道连接起来，把桥头跳车的落差进行缓冲处理，彻底解决跳车问题。
