Step-shaped bridge end transition slab structure
The invention relates to the technical field of bridge engineering, in particular to a step-shaped bridge end transition slab structure. The structure comprises a bridge girder, a bridge pavement surface layer, a step-shaped transition slab and a bridge abutment, wherein the end of the bridge girder is fixed to the top of the inner side of the bridge abutment, a steel corbel is arranged above the outer side of the bridge abutment, the bridge pavement surface layer is arranged above the bridge girder, the step-shaped transition slab is of a step-shaped structure, the left side of the top end of the step-shaped transition slab is in lap joint with the top of the steel corbel, buried soil is arranged between the upper surface of the step-shaped transition slab and the lower surface of the bridge pavement surface layer, a cushion layer is arranged below the step-shaped transition slab, and an inverted filter layer is arranged between the cushion layer and a soil base at the bottom. According to the invention, longitudinal deformation transmitted by the bridge girder can be absorbed, and meanwhile, deformation is transmitted to the foundation; on the other hand, dislocation between a road and a bridge can be effectively limited through the step-shaped transition slab, a settlement difference at the bridge head is reduced, and bumping at the bridge head caused by uneven settlement of the bridge and a road surface is prevented.
本发明涉及桥梁工程技术领域，尤其是一种阶梯状桥头搭板结构，包括桥梁主梁、桥梁路面面层、阶梯型搭板和桥台，所述桥梁主梁的端部固定于所述桥台的内侧顶部，所述桥台的外侧上方设有钢牛腿，所述桥梁路面面层设置于所述桥梁主梁上方；所述阶梯型搭板呈阶梯状结构，其顶端左侧与所述钢牛腿顶部搭接，其上表面与所述桥梁路面面层下表面之间设有埋土，其下方设有垫层，所述垫层与底部的土基之间设有反滤层。本发明能够吸收桥梁主梁传递的纵向变形，同时将变形传递至基础，另一方面利用阶梯型搭板能够有效限制路桥之间的错动，降低桥头处的沉降差，防止桥梁与路面产生不均匀沉降之后而导致的桥头跳车。
