Land-saving L-shaped retaining wall and construction method thereof
The invention provides a land-saving L-shaped retaining wall which comprises an outer pile foundation and a retaining wall unit arranged on the outer pile foundation, and a hinged disc retaining wall unit comprises a heel slab arranged on the outer pile foundation, a vertical wall vertically arranged on the heel slab and a haunch arranged between the top face of the heel slab and the side wall of the vertical wall. An outer connecting piece with the top end penetrating through the heel plate and inserted into the vertical wall is inserted into the hinged disc outer pile foundation. According to the L-shaped retaining wall, an existing cantilever retaining wall is improved, the toe board is removed, the stress of the bottom board is unbalanced due to the fact that the toe board is greatly shortened or completely removed, and then the requirement for the bearing capacity of a foundation below the vertical wall is high, the bearing capacity below the vertical wall is improved by arranging the outer pile foundation below the heel board, and therefore the bearing capacity of the foundation below the vertical wall is improved. Therefore, the stability problem caused by removing the toe board is solved, and permanent occupation of the land area is reduced.
本发明提供了一种节约土地的L型挡墙，包括外桩基、设置于外桩基上的挡墙单元，铰接盘挡墙单元包括设置于外桩基上的踵板、竖直设置于踵板上立壁、设置于踵板顶面和立壁侧壁之间的腋，铰接盘外桩基中插设有顶端穿过踵板并插入立壁中的外连接件。本实施例中的L型挡墙是针对现有悬臂挡墙的改良，其将趾板移除，而大幅缩短或完全移除趾板会导致底板应力不平衡，进而导致立壁下方的地基承载力要求高，本实施例通过在踵板下方设置外桩基来提升立壁下方的承载力，进而解决因移除趾板而造成的稳定性问题，从而实现减少用地面积的永久占用。
