Microbial sand pile grouting device and method in shallow muddy soft soil foundation
The invention discloses a microbe sand pile grouting device in a shallow muddy soft soil foundation, which comprises a conveying device, a pile forming sleeve, a grouting pipe and a grouting box, the grouting box is arranged at the inner bottom of the pile forming sleeve, the grouting box is communicated with one end of the grouting pipe, and the other end of the grouting pipe is communicated with the conveying device. The other end of the grouting pipe extends out of the upper end of the pile forming sleeve and communicates with a liquid conveying outlet of the conveying device; the grouting pipe and the grouting box are provided with a first grouting opening and a second grouting opening respectively, the second grouting box is provided with a one-way valve used for preventing grouting liquid from flowing into the grouting box through the second grouting opening, and the conveying device conveys microorganism bacterium liquid and cementing liquid into the grouting pipe. The invention also provides a method. The situation that sand particles remain in the grouting pipe for a long time, so that the sand particles flow backwards along with grout, and the grouting pipe is blocked can be avoided.
本发明公开了一种浅层淤泥质软土地基中微生物砂桩注浆装置，包括输送装置、成桩套筒、注浆管和注浆盒，所述注浆盒设于成桩套筒的内底部，所述注浆盒与注浆管的一端连通，注浆管的另一端伸出成桩套筒的上端与输送装置的输液出口连通；所述注浆管和注浆盒的分别开有第一注浆口和第二注浆口，且所述第二注浆盒上设有用于防止注浆液通过第二注浆口流入注浆盒内的单向阀，所述输送装置向注浆管内输入微生物菌液与胶结液。本发明还提供了一种方法。本发明可以避免砂土颗粒在注浆管内长时间残留，导致砂土颗粒随浆液倒灌回流，引起注浆管的堵塞的情况。
