Churning slurry hardening mechanism in the soil of the high-pressure injection of sclerosing agent used mainly cement, and adding additives precipitate or accelerate prevention solidified therein. Churning consolidation of body is a special cement - soil skeleton structure of soft foundation treatment, water-reactive cement soil more complex than pure mud. Glial membrane by the various components of the cement produced gradually developed into a gelatinous body connection, that the performance of the initial setting state of cement, with the continuous development of the hydration process, the gel absorbs moisture and expanding to produce crystals. Crystals and surrounded by gelatinous body mutual penetration, and reached a steady state, which is the beginning of hardening. Cement hydration process is a long process of residential excavation of soft ground treatment, hydration continued deep into the cement particles, until the water is completely absorbed by the soft-processing equipment, where to buy, gelatinous body filled up Solidificafion . In this process, the strength of the body will continue to increase consolidation. When the high pressure jet grouting pile jet grouting process control require disassembly grouting pipe, stop lifting and rotating various soft-processing equipment, and stop feeding the pulp, and then gradually reduce the amount of wind and water, and finally shut down. When disassembled continue jet grouting, the boot order must comply with the provision. After the jet grouting to achieve the designed depth, you can stop the wind, water, continue to use the injection pump grouting, until the water back out of the mud after the opening, you can stop grouting, injection pump and the suction pipe is moved water tank, pumping water to the mud pump and quantitative grouting slurry pipeline top out, then stop the pump. Long pile of deep injection shall geological profile and groundwater and other information, at different depths for different strata soil conditions, the choice of the appropriate injection parameters in order to obtain uniform solid long pile. After the jet grouting operation, due to the analysis of the role of water slurry, generally have different levels of contraction, so that the top of the body appear consolidation pockets, should be timely and grout cement ratio of 0.6 supplemental irrigation. In the take slurry process, often there is a certain amount of soil particles, along with a portion of the slurry grouting wall out of the ground. Oozing slurry grouting less than 20% of normal, more than 20% or not take slurry, it should identify the causes and take appropriate measures
