Recoverable pumping and grouting device for in-situ pile forming of microbial sand pile and construction method
The invention discloses a recyclable grouting and pumping device for in-situ pile forming of a microbial sand pile and a construction method, the recyclable grouting and pumping device comprises a segmented grouting device, a segmented slurry pumping device, a grouting pump and a slurry pumping pump, the segmented grouting device is connected with the grouting pump, and the segmented slurry pumping device is connected with the slurry pumping pump; the segmented grouting device comprises a pumping and grouting core pipe and a pumping and grouting sleeve, the lower end of the pumping and grouting core pipe and the lower end of the pumping and grouting sleeve are sealed, a plurality of pumping and grouting holes are formed in the pumping and grouting core pipe, two sets of sealing rings are further arranged outside the pumping and grouting sleeve, and the two sets of sealing rings, the pumping and grouting core pipe and the pumping and grouting sleeve form an annular grouting cavity. The annular grouting chamber is communicated with the outside through the grouting hole; the construction method further comprises the construction method of the steps S1 to S10. The method is suitable for various bad foundations, a reinforcing area and a non-reinforcing area are isolated through the degradable waterproof geotechnical bags, the reinforcing range is controlled, the using amount of slurry is reduced, waste liquid recycling treatment is achieved, and degradation can be achieved in the natural environment.
本发明公开了一种微生物砂桩原位成桩可回收抽注浆装置及施工方法，包括分段注浆装置、分段抽浆装置、注浆泵和抽浆泵，分段注浆装置与注浆泵连接，分段抽浆装置与抽浆泵连接；分段注浆装置包括抽注浆芯管和抽注浆套管，抽注浆芯管和抽注浆套管的下端密封，抽注浆芯管上设置有若干抽注浆孔，抽注浆套管的外部还设置有两组密封圈，两组密封圈与抽注浆芯管、抽注浆套管形成环状注浆腔室，环状注浆腔室与通过注浆孔与外部连通；还包括步骤S1‑S10的施工方法。本发明适用于各种不良地基，利用可降解防水土工袋隔离加固区与非加固区，控制加固范围，减少浆液的用量，实现废液回收处理，并可在自然环境下降解。
