Highway embankment widening structure and construction method thereof
The invention discloses a highway embankment widening structure and a construction method thereof.The highway embankment widening structure comprises a drainage padding layer which is laid on an original embankment of an existing highway, a drainage groove is formed in the original embankment, and padding of the drainage padding layer is filled in the drainage groove; the pressure-bearing grid is laid at the upper part of the drainage padding layer; the lower parts of the supporting piles are embedded in the drainage padding layer, and the upper parts of the supporting piles are arranged in meshes of the pressure-bearing grids in a penetrating manner and extend to the upper parts of the pressure-bearing grids; the first concrete is paved on the pressure-bearing grid, the pressure-bearing grid and the multiple bearing piles are wrapped with the first concrete so as to form a hardened pavement layer in a consolidation mode, and the hardened pavement layer is flush with the pavement of the existing highway; and the filler is filled on one side, far away from the existing highway, of the drainage padding layer and the hardened pavement layer to form a slope protection. The problem that after an existing embankment is widened, the height difference of new and old pavements is prone to occurring is solved.
本发明公开了一种公路路堤拓宽结构及其施工方法，包括：排水垫料层，摊铺于既有公路的原路堤处，所述原路堤处开设有排水槽，所述排水垫料层的垫料填充于所述排水槽中；承压网格，铺设于所述排水垫料层的上部；多根支承桩，所述支承桩的下部埋设于所述排水垫料层中，所述支承桩的上部穿设于所述承压网格的网孔且伸至所述承压网格的上部；第一混凝土，摊铺于所述承压网格，所述第一混凝土包覆于所述承压网格和多根所述支承桩以固结形成硬化路面层，所述硬化路面层与所述既有公路的路面齐平；填料，填筑于所述排水垫料层和所述硬化路面层的远离所述既有公路的一侧以形成护坡。本发明解决了现有的路堤加宽后，新旧路面容易出现路面高度差异的问题。
