U-shaped bridge abutment provided with pressure reducing plate
The invention discloses a U-shaped bridge abutment provided with a pressure reducing plate; the U-shaped bridge abutment comprises a foundation, side wall bodies are arranged on the two sides of the upper surface of the foundation, a front wall body is arranged at the front ends of the side wall bodies, a hollow cavity is formed between the side wall bodies and the front wall body, a groove is formed in the front side of the upper end of the front wall body, and an abutment cap is arranged on the front side of the upper end of the front wall body. A gravel filling layer, waterproof geotechnical cloth and a pressure reduction structure layer are arranged in the hollow cavity in the vertical direction, the gravel filling layer, the waterproof geotechnical cloth and the pressure reduction structure layer form a partition bin layer, and all the partition bin layers are sequentially arranged from bottom to top. In the using process, in order to solve problems of bumping at the bridge head caused by the large settlement amount of filled soil of the bridge abutment, wall surface cracking caused by the large soil side pressure and the like, a pressure reduction structure is independently arranged, so that foundation deformation is uniform and excessive, the settlement difference of the foundations is reduced, bumping at the bridge head is prevented, and the driving stability is ensured.
本发明公开了一种设置减压板的U形桥台，包括基础，基础上表面的两侧设有侧墙体，侧墙体的前端共同设有前墙体，侧墙体和前墙体之间形成中空腔，前墙体上端的前侧开设有凹槽并设有台帽，中空腔的内部沿竖直方向分别设置有砂砾填充层、防水土工布和减压结构层，砂砾填充层、防水土工布和减压结构层组成一个分隔仓层，每个分隔仓层沿从下到上的方向依次设置。本发明在投入使用的过程中，针对桥台填土沉降量较大导致的桥头跳车，以及土侧压力较大导致的墙面开裂等问题，独立设置有减压结构，使地基变形均匀过度，减少它们的沉降差，防止桥头跳车，保证行车的平稳性。
