| Abstract | Laboratory researches, realized by authors, confirm that cement soil material with initial content of sand particles more than 25 % have the higher hardness characteristics. Depends of size (diameter) of cement soil columns on connection of particles of soil massive and pressure of solution forcing in technology of jet grouting have been established by field researches. The results of executed works allow to wide existent possibilities of jet grouting, especially its active usage in clay soils, that is actual during building in Moscow and other cities with similar mining-geological conditions (clay soils occupy about 75% of the Earth surface). |
