Аннотация

An analysis of the working fluid pressure losses in the pressure hoses during soil jet cementation was done, which confirmed the possibility of initial pressure reducing with the length of the pressure line increase. When providing experimental work at a small distance from the building complex, the results must be adjusted with regard the pressure line lengthening for all working soil-cement elements installation. The most correct way is to carry out experimental work using the pressure hose with the length equal to the largest distance of the working soil-cement elements from the technological complex. In other cases, it is necessary to adjust the final pressure level, as well as the possible reduction in the diameter of the soil-cement elements in accordance with the formulas given in the article.
