Roadbed structure suitable for bridge-road connection and construction method
The embodiment of the invention provides a roadbed structure suitable for bridge-road connection and a construction method, and belongs to the technical field of road-bridge connection. The roadbed structure comprises a bridge and a roadbed, and the bridge comprises a edge beam located on one side of the bridge in the width direction. The roadbed comprises a base layer, a plurality of backfill layers and a plurality of retaining walls, the base layer is provided with a protection slope, the backfill layers are sequentially arranged on the base layer from bottom to top, and one retaining wall is arranged on the side, close to the protection slope, of each backfill layer in the horizontal direction; in the every two adjacent retaining walls, the retaining wall located on the upper side is farther away from the slope protection in the horizontal direction than the retaining wall located on the lower side; and the retaining wall on the uppermost side of the retaining walls is connected to the edge beam. The roadbed structure can improve the problem of poor bridge-road connection stability.
本申请实施例提供了一种适用于桥路连接的路基结构及施工方法，属于路桥连接技术领域。路基结构包括桥梁和路基，桥梁包括位于其宽度方向上的一侧的边梁。路基包括基层、多个回填层和多个挡土墙，基层具有护坡，多个回填层从下至上依次设置于基层，每个回填层在水平方向上靠近护坡的一侧设置有一个挡土墙，每相邻的两个挡土墙中，位于上侧的挡土墙较位于下侧的挡土墙在水平方向上更远离护坡。多个挡土墙中最上侧的挡土墙连接于边梁。这种路基结构能够改善桥路连接稳定性不佳的问题。
