Abstract
Purpose. The purpose of this work is to consider the prospects for the use of jet grouting in urban development. On the example of the considered engineering-geological conditions to show the possibility of wide application of soil-cement elements. Methodology. To consider the main characteristic features of jet grouting, which prevail over traditional geotechnical technologies. To show the possibility of performing soil-cement elements not only in the conditions of strengthening the soil bases, but also in the conditions of anti-filtration elements when performing the protection of ditches. To present the ranges of strength characteristics of soil-cement material for soil conditions of Ukraine. Findings. The type and physical and mechanical properties of soils in which the jet-grouted element is performed will be one of the main factors influencing the geometric size of the elements and the strength of the soil-cement material. Originality. Collected and analyzed strength characteristics of soil-cement material and the presented ranges of their numerical values will allow to use them for future design of jet-routed elements in different soil conditions of Ukraine without the available personal developed practical base. Practical implications. In the progressive rhythm of urban development, the issue of new construction in the immediate vicinity of existing buildings, or the reconstruction of those in disrepair is acute. Due to its features and advantages, the technology of jet cementation allows to solve construction problems where other geotechnologies do not have the opportunity to be applied. Low dynamic impact will allow to perform soil-cement elements at strengthening of buildings and constructions in an emergency condition, low water permeability - to use jet elements as antifiltration, both single, and in joint work with other elements of designs of protection of ditches. Numerical experimental values of the strength of the material obtained by performing jet cementation, will predict the strength characteristics of future soil-cement elements.
