Pretreatment method for high-pressure jet grouting pile construction without slurry return
The invention discloses a pretreatment method without slurry return in high-pressure jet grouting pile construction, which is characterized in that a slurry jacking process is set in a drilling construction stage before slurry spraying construction, a slurry jacking material is replaced by preset adjusting slurry, treatment can be completed by using a drilling machine for pre-drilling of a high-pressure jet grouting pile, and slurry jacking construction is completed while pre-drilling of the high-pressure jet grouting pile is performed. Compared with the prior art, the method has the advantages that long-time static spraying of the high-pressure jet grouting pile is avoided when the high-pressure jet grouting pile does not return during grout spraying, construction time is effectively saved, construction efficiency is improved by more than 30%, materials for preparing the slurry are convenient to obtain, cost is low, a treatment mode of adding water glass in the prior art is not needed, and pollution to the environment is greatly reduced.
本发明公开了一种高压旋喷桩施工不返浆的预处理方法，在喷浆施工前钻孔施工阶段同时设置了压浆工序，将压浆材料换成预先设置的调节泥浆，利用高压旋喷桩预钻孔的钻机即可完成处理，且在高压旋喷桩预钻孔的同时完成压浆施工，避免了高压旋喷桩遇喷浆不返浆时长时间静喷的情况，有效的节省了施工时间，提高了施工效率，提高施工效率30％以上，且调制泥浆取材方便，成本低，无需如现有技术所采用加入水玻璃的处理方式，大大减少了对环境的污染。
