The technology is based on the consolidation of soils by their erosion and mixing with a high-pressure jet of cement mortar. Jet 1 - is the destruction of the soil produced by a stream of cement mortar under pressure. Building mixture is supplied under high pressure by a powerful pump directly into the soil. The essence of this process reflects the name of the technology in which the word grouting means “filling with cement mortar”. A hole is formed under pressure and immediately mixes with the cement. This technology involves the implementation of pile structures with a diameter of 0.3–1 m, depending on the properties of the soil. Application areas:
As a result of jet cementation, ground-cement columns (piles) with a diameter of 300 to 2500 mm are formed, which are effectively used in the following directions:
- for strengthening of the bases of different types;
- soil leveling by the introduction of reinforcing elements;
- vertical or horizontal filtering curtains for permanent and temporary use;
- soil consolidation during tunneling and road construction;
- strengthening slopes and slopes;
- fixing soils at the base of the projected foundations;
- filling underground workings and karst cavities;
- superstructures of buildings and deepening of basements;
- fencing pits and creating retaining walls.
