Anti-leakage backfill construction method for basement outer wall of deep foundation pit fat groove
The invention discloses a deep foundation pit fat groove basement outer wall anti-seepage backfill construction method which comprises the following steps: S1, outer wall waterproof base layer treatment: firstly, carrying out layer treatment on an outer wall base layer, and entering a next procedure after the outer wall base layer is qualified in inspection; s2, polyurethane waterproof paint is brushed, specifically, first brushing is conducted on internal and external corners and the roots of the pipelines, then second large-area brushing is conducted, and the next procedure is conducted after the brushing thickness is accepted and accepted; s3, slurry preparation; s4, preparation of premixed liquid solidified soil: calculating the proportion of the curing agent to the slurry according to the mass ratio, firstly mixing the curing agent with water, then pouring the diluted curing agent into the slurry, and uniformly stirring; s5, backfilling solidified soil; and S6, curing and forming are conducted, specifically, after backfilling of each layer or the top layer is completed, curing is conducted on the solidified soil. In the engineering basement outer wall backfilling process, the construction quality of the waterproof layer and the backfilling soil is guaranteed, the construction difficulty and the safety risk are reduced, and the purposes of reducing cost and improving efficiency are achieved.
本发明公开一种深基坑肥槽地下室外墙防渗漏回填施工方法，包括如下步骤：S1、外墙防水基层处理：首先对外墙基层进行层处理，报验合格后进入下道工序；S2、聚氨酯防水涂料涂刷：先对阴阳角和管道根部进行第一道涂刷，然后进行第二道大面积涂刷，涂刷厚度验收合格后进入下道工序；S3、泥浆制备；S4、预拌液态固化土制备：按照质量比计算出固化剂与泥浆的比例，先将固化剂与水进行混合，然后再将稀释的固化剂倒入泥浆中搅拌均匀；S5、固化土回填；S6、养护成型：每一层或顶层回填完成后，对固化土进行养护。本发明在工程地下室外墙回填过程中保证防水层与回填土的施工质量，降低施工难度与安全风险，达到降本增效的目的。
