In recent years, considerable attention has been paid to the development of technologies for strengthening the foundation soils, which ultimately allows the use of shallow foundations. One of these areas is the arrangement of soil-cement elements using various technologies. The article focuses on increasing the bearing capacity of soil-cement elements manufactured using deep soilmixing technology. The construction of soil-cement elements is possible using various technologies, but the deep soil mixing technology has a number of advantages, including high mobility of the equipment complex, the ability to work in constrained conditions, easy variation of soil-cement elements parameters by using replaceable equipment, minimal impact on the environment and workers in terms of occupational safety, independence of the technological process from external factors, the ability to constantly monitor material consumption This method of producing soil-cement elements by mixing without removing the soil makes it possible to perform work without using casing or other measures to ensure the stability of a borehole. However, as foundation construction practice has shown, the main disadvantage of soil-cement elements is their relatively low material strength. Increasing the strength of soil-cement elements is possible in various ways - by adding more cement, plasticizing or other additives, fly ash, vibration, reinforcement with synthetic materials, etc. However, the most effective way to increase the bearing capacity is to reinforce them with rolled profiles or spatial frames. Reinforcement with frames is more effective, but immersion of the frame in soil cement is problematic, so the paper proposes a method of immersion of the frame that allows increasing the depth of reinforcement of soil cement elements.
