Bridge abutment rear roadbed reinforcing column connecting plate structure
The invention discloses a bridge abutment rear roadbed reinforcing column connecting plate structure, and relates to the technical field of bridges, the bridge abutment rear roadbed reinforcing structure comprises a transition area bridge plate, a deep subsidence area bridge plate, a cylindrical pile and a bridge pier, the transition area bridge plate and the deep subsidence area bridge plate are arranged in a spliced mode; the piers are located on the lower side of the middle of the transition area bridge plate and at the joint of the transition area bridge plate and the deeper area bridge plate, the cylindrical piles are fixedly arranged at the lower ends of the piers and on the lower side of the deeper area bridge plate, the cylindrical piles are fixedly connected with the deeper area bridge plate, and the cylindrical piles penetrate through a peat soil layer below the ground. And the lower ends of the cylindrical piles are positioned in the silty clay layer below the peat soil layer. The cylindrical piles penetrate through the softer peat soil layer and are supported in the harder silty clay layer, the silty clay layer serves as a bearing layer to stably support the bridge plate, the bridge plate is prevented from collapsing, the roadbed behind the bridge abutment is stable, subsidence of the deep unstable soil layer can be radically treated, the cylindrical piles are located under the ground, and maintenance traces cannot be seen after recovery.
本发明公开了一种桥台后路基加固柱接板结构，涉及桥梁技术领域，桥台后路基加固结构包括过渡区桥板、深陷区桥板、圆柱桩和桥墩，过渡区桥板和深陷区桥板拼接设置，桥墩位于过渡区桥板中部位置的下侧以及过渡区桥板与深陷区桥板的接缝处，圆柱桩固定设置在桥墩的下端以及深陷区桥板的下侧，圆柱桩和深陷区桥板固定连接，圆柱桩穿过地面下方的泥炭土层，圆柱桩的下端位于泥炭土层下方的粉质粘土层内。圆柱桩穿过较软的泥炭土层，支撑在较硬的粉质粘土层内，粉质粘土层作为持力层，形成对桥板的稳固支撑，避免桥板塌陷，使桥台后路基稳固，能根治深层不稳定土层沉陷，并且圆柱桩位于地面以下，恢复后看不出维修过的痕迹。
