Prefabricated inverted filter retaining wall and construction method thereof
The invention discloses a prefabricated inverted filter retaining wall and a construction method thereof.The prefabricated and split type inverted filter is installed on the inner side wall of a wall body of the retaining wall and comprises a plurality of inverted filter units which are vertically distributed, and the inverted filter units correspond to all sets of drainage holes one to one; the inside of each inverted filter unit is made of a plastic material with a mesh permeable structure, the outside of each inverted filter unit is wrapped with inverted filter geotechnical cloth, each inverted filter unit comprises a plate-shaped main body and protrusions distributed at the lower end of one face of the plate-shaped main body, the plate-shaped main bodies are attached to the inner side wall of the wall body, and the protrusions are inserted into the drainage holes of the corresponding sets; the backfill soil is arranged in a layered mode, anti-seepage geotechnical cloth is laid on the interfaces of the adjacent layers of backfill soil, the interfaces of all the layers of backfill soil correspond to all the sets of drainage holes in a one-to-one mode, and the bottom face of the lowermost layer of plate-shaped body is supported on the lowermost layer of backfill soil in an attached mode through the anti-seepage geotechnical cloth. And the bottom surfaces of the rest layers of plate-shaped main bodies are attached and supported on the top surface of the next layer of plate-shaped main body through the impermeable geotechnical cloth. The construction speed is increased, and water is prevented from being gathered at the bottom of the wall.
本发明公开一种预制反滤层挡土墙及其施工方法，该挡土墙的墙体内侧壁上安装有预制且分体式的反滤层，反滤层包括若干个竖向分布的反滤单元，各反滤单元与各组排水孔一一对应，反滤单元的内部采用具有网孔透水结构的塑料材质、外部包裹反滤土工布，反滤单元包括板状主体和分布在板状主体一面下端的凸起，板状主体贴在墙体内侧壁上、各凸起插放在对应组的各排水孔内；回填土分层设置且相邻层回填土的分界面上铺设防渗土工布，各层回填土分界面与各组排水孔一一对应，最下层板状主体底面通过防渗土工布贴合支撑在最下层回填土上，其余层的板状主体底面均通过防渗土工布贴合支撑在下一层板状主体顶面上。本发明提高了施工速度，避免了水汇集于墙底部。
