Embankment widening method
The invention discloses an embankment widening method which comprises the following steps: excavating foundation pits at intervals along the trend of a line on a foundation of a slope toe of an embankment to be widened, and burying stand column lower end foundations in the foundation pits; placing triangular rib plates between the inner sides of the stand columns and the slope surface of the sideslope of the embankment, wherein the upper edges of the triangular rib plates are flush with the stand columns in height, the lower edges are attached to the slope surface, and the side edges are in rigid connection with the inner sides of the stand columns; arranging soil retaining panels in lap joint with the inner sides of the adjacent stand columns, then compacting filled soil between the triangular rib plates in a layered mode till a soil filling face is flush with the embankment face, and the slope rate of the soil filling side slope above the stand columns is consistent with that of theoriginal embankment side slope face. The method has the beneficial effects that the soil pressure acting on the soil retaining panels is balanced through the friction effect between the triangular rib plates and the newly-filled soil body, so that the anti-sliding and anti-overturning stability of the widened new roadbed is guaranteed. In the construction process, the slope does not need to be excavated, and disturbance to an original roadbed is reduced.
本发明公开了一种路堤拓宽方法，包括步骤：在需拓宽路堤的坡脚的地基上，沿线路走向按间距开挖基坑，将立柱下端基础埋置于基坑内。在立柱内侧与路堤的边坡坡面之间，放置三角形肋板；三角形肋板的上边与立柱的高度平齐，下边与边坡坡面贴合，侧边与立柱的内侧刚性连接。在相邻立柱的内侧，搭接挡土面板，然后在三角形肋板之间分层压实填筑的土体，直至填土面与路堤面平齐，立柱以上的填土边坡与原路堤边坡坡面的坡率一致。本发明的有益效果在于，通过三角形肋板与新填筑土体间的摩擦效应来平衡作用于挡土板的土压力，以此保证拓宽后新路基的抗滑抗倾覆稳定性能。施工过程中无需对边坡进行开挖，减小了对原路基的扰动。
