Deep foundation pit corner waterproof construction method
The invention discloses a deep foundation pit corner waterproof construction method. The construction method comprises the steps of jet grouting pile machine positioning, cement paste preparation, drilling, guniting, pile forming and slurry supplementing, the adopted high-pressure jet grouting technology is a double-pipe method which can also be called as a slurry gas jetting method, and a doublegrouting pipe is adopted for transversely jetting out jet flows of high-pressure slurry and air at the same time, so that a soil body is impacted and destroyed; under the combined action of the high-pressure slurry and the airflow surrounding the outer ring of the high-pressure slurry, the soil body is destroyed and punched to form a solidified body; and the construction method can effectively reinforce corner waterproof curtain cold joints of a deep foundation pit, the waterproof consolidation performance of surrounding soil can be enhanced, the corner cold joints can be treated, the number of input mechanical materials is small, the cost is low, and the construction speed is high.
本发明公开一种深基坑角点防水施工方法，包括步骤：旋喷桩机定位，水泥浆的制备,钻孔，喷浆，成桩，补浆，其采用的高压旋喷工艺为二重管法，也可以称为浆液气体喷射法，是采用二重注浆管同时将高压泥浆和空气两种介质喷射流横向喷射出，冲击破坏土体；在高压浆液和它外圈环绕气流的共同作用下，破坏、冲切土体形成固结体；其能有效对深基坑角点止水帷幕冷缝进行补强，既能增强周围土体防水固结性能，又可以对角点冷缝进行处理，投入机械材料少、成本低、施工速度快。
