Composite roadbed composite structure suitable for bridgehead retaining wall road section
A composite roadbed composite structure suitable for a bridgehead retaining wall road section comprises a retaining wall used for protection, and a foundation of the retaining wall is buried to the lower side of a ground line and is backfilled and fixed through filler; a light roadbed and a pavement layer arranged on the upper side of the light roadbed are arranged on the inner side of the retaining wall; an anti-collision guardrail fixed to the top of the retaining wall is arranged on the edge of the outer side of the pavement layer. A lower-layer roadbed is arranged between the bottom surface of the light roadbed and the ground line after surface cleaning, and a transition layer is arranged between the top surface of the light roadbed and the bottom surface of the road surface; the lower layer roadbed is made of soil and stone filler, and the transition layer is made of a reinforced concrete layer or soil and stone filler. The interlayer roadbed structure is formed by the transition layer, the light roadbed and the soil roadbed from top to bottom; on the premise of meeting the post-construction settlement requirement of a bridgehead road section, the size of the retaining wall can be reduced to the maximum extent, the stability of the retaining wall is guaranteed, and the retaining wall is economical and safe.
一种适用于桥头挡墙路段的复合式路基组合结构，包括用于防护的挡土墙，挡土墙的基础埋设至地面线的下侧，并用填料将其回填固定；位于挡土墙的内侧设置有轻质路基，以及设置在轻质路基上侧的路面层；位于路面层外侧的边缘处设置有与挡土墙顶部固定的防撞护栏；所述轻质路基的底面与清表后的地面线之间设置有下层路基，轻质路基的顶面与路面的底面之间设置有过渡层；所述的下层路基采用土、石填料，所述过渡层采用钢筋混凝土层或土、石填料。本发明通过从上至下的过渡层、轻质路基和和土质路基，形成夹层路基结构；在满足桥头路段工后沉降要求的前提下，可最大限度的减小挡墙尺寸，保证挡墙的稳定性，既经济又安全。
