Road and bridge transition structure for controlling bumping at bridge head and construction method
The invention discloses a road and bridge transition structure for controlling bumping at a bridge head and a construction method. A bearing platform is arranged at the top of a bridge abutment body, the right side of the bearing platform bears a beam body through a support, the left side of the bearing platform bears a butt strap, a groove is formed in the bottom of the butt strap, and a telescopic system is arranged in the groove. A slurry inlet pipe is embedded in the foundation roadbed, and a soil pressure meter is used for controlling a ball valve to automatically consolidate the soil body in the area. The roadbed lifting system comprises a lower groove body and an upper cover plate which are matched in an inserted mode, and a feeding pipe penetrates through the upper cover plate to fill expansive cement into the lower groove body. The water inlet pipe penetrates into the lower groove body from the bottom, sprayed water mist is combined with the expansive cement to form a solid, and the upper cover plate is jacked up so as to make up settlement of the roadbed. According to the invention, the horizontal and vertical deformation of the roadbed can be controlled, the settlement deformation rule of each position of the roadbed can be analyzed through soil pressure signals, and the settlement area is grouted and consolidated; if the large settlement difference still exists after solidification, the subgrade in the settlement area is lifted through the subgrade lifting system, and the phenomenon of bumping at the bridge head is reduced.
本发明公开了一种控制桥头跳车的路桥过渡结构及施工方法，桥台台身顶部布设承台，承台右侧通过支座承载梁体，承台左侧承载搭板，搭板底部设置凹槽，凹槽内布设伸缩系统。基础路基内部埋设进浆管，通过与土压力计控制球阀自动对该区域土体进行固结。路基抬升系统包括插接配合的下部槽体和上盖板，进料管穿过上盖板向下部槽体内灌入膨胀水泥；入水管从底部穿入下部槽体内，喷出水雾与膨胀水泥结合为固体，将上盖板顶起从而弥补路基的沉降。本发明能控制路基的水平与竖向变形，又能通过土压力信号分析路基各位置的沉降变形规律，并对沉降区域进行注浆固结；固结后仍有较大沉降差，则通过路基抬升系统抬升沉降区域路基，降低桥头跳车现象的发生。
