[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 have a higher organic matter, 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. [Tianjin-strong high-pressure pump Co., Ltd. to recommend Star Products] 1, before the high-pressure jet grouting construction, the case must have a complete project construction materials and engineering geological survey near the pipelines, buildings, structures and other public facilities, when groundwater When the flow speed, jet grouting rig tunnel parameters, should be special hydrogeological investigation. 2, when the abnormality occurred during construction, should immediately stop the construction, Zibo tunnel Jet rig, joint analysis by the relevant units or construction units of the organization supervising the investigation, design and construction, the tunnel Jet rig equipment, to solve the problem, the crawler We can continue the construction of the tunnel Jet rig, eliminate quality problems, and should form documents. 3, the official site injection test should be carried out prior to construction in order to determine the appropriate construction parameters
