Construction method for inverted filter of retaining wall
The invention discloses a construction method for an inverted filter of a retaining wall. Comprising the following steps that S1, a foundation trench is excavated; s2, a cushion layer is constructed, a first vertical rod and a second vertical rod are embedded in the inner end and the outer end of the cushion layer respectively, and a third vertical rod is embedded in the outer side of the cushion layer; s3, cushion layer maintenance; 4, a single-side formwork is arranged on the inner side of the second vertical rod, an inclined support is erected on the outer side of the single-side formwork, and the lower end of the inclined support is connected with the third vertical rod; s5, an inner support is erected on the inner side of the single-side formwork, and the lower end of the inner support is connected with the first vertical rod; s6, a pipe hole in the inner end of the water pipe is filled with a steel wire ball and graded broken stone; s7, the inner end of the drainage pipe is inserted into the drainage hole; s8, a single-side formwork is pulled and fixed; and S9, pouring the retaining wall. The outer side of the wall body of the retaining wall adopts the single-side formwork, the inner side of the wall body adopts the soil formwork, the earthwork excavation volume is greatly reduced, construction is simple, the construction period is shortened, the inverted filter layer is located in the drainage pipe, the work amount of backfilling soil and installing the inverted filter layer is reduced, and the construction cost is saved.
本发明公开了一种挡土墙反滤层施工方法。包括如下步骤：S1、基槽开挖；S2、垫层施工，垫层的内端和外端分预埋第一立杆和第二立杆，垫层的外侧埋设第三立杆；S3、垫层养护；4、单侧模板置于第二立杆的内侧，单侧模板的外侧支设斜支撑，斜支撑的下端与第三立杆连接；S5、单侧模板的内侧支设内支撑，内支撑的下端与第一立杆连接；S6、水管内端的管孔内装入钢丝团和级配碎石；S7、泄水管内端插入泄水孔内；S8、单侧模板拉结固定；S9、挡土墙浇筑。本发明的挡土墙的墙身外侧采用单侧支模、内侧采用土模，大幅减少土方开挖量，施工简单，节约工期，反滤层位于泄水管内，减少了回填土和安装反滤层的工程量，节约施工成本。
