(1) The high-pressure jet grouting method is suitable for the treatment of silt, silty soil, fluid-plastic soil, soft plastic soil or plastic-plastic viscous soil high-pressure rotary jet pile pictures, silt, sand soil, loess, plain fill soil and gravel soil and other foundations.
(2) When the soil contains a large number of large-particle size stones, hard clay soil, a large number of plant roots or too much organic matter, the application degree of the reinforcement of silt and peat soil and collapsible loess foundation of existing buildings should be determined according to the field test results.Its applicability and technical parameters should be determined by high-pressure jet grouting test.
(3) The high-pressure jet grouting method is applied to the strata of bedrock and gravel in the bedrock and gravel soil, the groundwater flow rate is too large, and the groundwater has been eroded, and the groundwater is erosive and should be used with caution.
(4) High pressure jet grouting method can be used for existing buildings and new buildings foundation reinforcement treatment, and stop water heavy curtain of deep foundation pit at the bottom of the cover soil or water, foundation pit slope reinforcement, prevent the piping and uplift, underground large-diameter pipe enclosure and strengthening, the subway engineering of soil reinforcement or waterproof, DAMS, dikes,, dam dam foundation seepage control river levees and building underground reservoir impervious dam engineering, etc.
