Self-adaptive transition structure for preventing and treating bumping at bridge head
The invention provides a self-adaptive transition structure for preventing and treating bumping at a bridge head. The self-adaptive transition structure comprises a transition structure body and a sleeper beam, one end of the transition structure body is connected to a bridge abutment, and the bottom of the other end of the transition structure body abuts against the top face of the sleeper beam located in a road. When the sleeper beam settles along with the road, the transition structure body can rotate with the joint of the transition structure body and the bridge abutment as the circle center, smooth transition between the bridge abutment and the road can be achieved, and the problem of bumping at the bridge head is avoided. The bottom edge of the other end of the transition structure body always abuts against the top face of the sleeper beam, and a first reserved space is formed between the bottom of one end of the transition structure body and a road on the lower side of the transition structure body, so that the transition structure body can only receive settlement at the position of the sleeper beam and rotate along with the settlement at the position. And the influence of irregular settlement of the road on the rotation process of the transition structure body is avoided.
本申请提供了用于桥头跳车防治的自适应过渡结构。该自适应过渡结构包括过渡结构本体和枕梁，过渡结构本体的一端连接于桥台，过渡结构本体的另一端的底部压抵于位于道路中的枕梁的顶面。枕梁随道路沉降时，过渡结构本体能够以过渡结构本体与桥台的连接处为圆心进行转动，使桥台与道路能够平顺过渡，避免桥头跳车问题。并且过渡结构本体的另一端的底部棱边始终压抵于枕梁的顶面，过渡结构本体的一端的底部与其下侧的道路之间设置有第一预留空间，使得过渡结构本体仅能接收到枕梁处的沉降，并随此处的沉降而进行旋转运动，避免了道路不规则沉降对过渡结构本体转动过程的影响。
