[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] High Pressure Injection laws generally provide a high-pressure jet grouting method for handling silt, silty soil, flow plastic, soft plastic plastic clay soil, silt, sand , loess, plain fill and gravel soil and other foundations. When the soil contains more large-size stone, a large number of plant roots or higher organic matter, high pressure pump manufacturer, and groundwater flow rate is too large and has been gushing water projects, should determine their suitability based on the field test results. 2 High Pressure Injection Method can be used for both new construction and reinforcement of building foundations, deep excavation, soil reinforcement subway and other projects or waterproof. High Pressure Injection Method 3 stars Jet, fixed spray jet and swing three categories. According to project needs and soil conditions, respectively single-tube method, twin-tube method and the three methods. Reinforcement can be divided into a columnar shape, the walls, strip and block. Four pairs of existing buildings to collect information on the history and current situation, the neighboring buildings and an underground thing, etc. when developing the high-pressure jet grouting program. 5 High Pressure Injection scheme determined, should be combined with engineering conducted field trials, experimental construction or to determine the construction and process parameters based on engineering experience. After the high pressure grouting pile reinforcement soft soil foundation as common method is to use grouting pipe rig will drill with a special nozzle to a predetermined depth, Weihai high-pressure pump, high pressure equipment so that a weak soil consolidation agent slurry or Water has become more high-pressure jet 20mpa ejected from the nozzle, impact damage weak foundation soil, and with the active pipe rotation and promotion, grouting pipe driven at a constant speed of rotation and upward pressure pump manufacturers, wholesale, the slurry and soil particles forced mixing, after mixing with the soil particles in the slurry body to be set and harden to form a high strength, low compression of the soil complex.
