Abstract

The invention discloses a bridge structure. It includes abutment and floor plank between which bridge beam is set. Its features are that the transition floor plank is set between the floor plank and back driveway plate; and actively connected with them. The bridge beam is set under the connection of the floor plank and the transition floor plank. And its upside is set movable backing block. The floor plank and the transition floor plank are bearing on the movable backing block. Its advantage is that it can remove step caused by abutment back different sinking. When part of groundwork of abutment back is sinking, one end of the transition floor plank can fall along with driveway plate to form an inclined plane with gentle grade to avoid step generating.

Description

technical field [0001] The invention relates to a traffic bridge, in particular to a bridge structure. Background technique [0002] Existing highway bridges generally consist of abutments, bridges, and bridge prefabricated panels. The most common phenomenon in existing highway bridges is that at the junction of the highway and the bridge, the steps formed by the differential settlement of the foundation at the back of the highway abutment and the bridge abutment cause the vehicle to jump. Vehicle jumping at the bridge head is a major technical problem that has plagued the highway industry for many years. Car jumping not only causes discomfort in driving, reduces the speed of vehicles and the capacity of roads, but also affects the service life of bridges and roads and vehicles, and sometimes even causes traffic accidents. To keep the bridge unimpeded, the bridge needs to be maintained and repaired frequently, which will increase the bridge road maintenance work and costs....
