[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] envelope envelopes high pressure spraying pile high pressure spraying pile for processing sludge, silty soil, flow plastic, soft plastic or plastic clay soil, vegetarian filling soil clay, silt, sand, gravel soil, etc., and when the soil contains more large-size stone, a large number of plant roots or more organic and groundwater flow rate is too large, you need to use caution or based on field test results to determine its applicability. During the construction method, were used to single-tube method, a double-tube method, triple tube; in spray form can be divided into jet grouting, jet set jet and swing three, reinforcement depth is generally greater than 5.0m. Having a pile speed, high efficiency, construction no vibration, no noise and other characteristics; but the construction of the grout loss (waste) are more construction will cause a range of environmental pollution. Churning process, often there is a certain amount of soil particles, along with a portion of the slurry wall grouting pipe out of the ground, through the mud spillover observation, you can keep abreast of the soil conditions determine the approximate effect Jet and determine reasonable parameters, etc., Shijingshan jet grouting rig, based on experience, take the pulp (with a soil particles, water and slurry) of less than 20% of normal grouting phenomenon, Beijing crawler rotary spray rig, more than 20% or not When take slurry, should promptly take appropriate measures to identify the cause. 1, the flow rate constant and the pressure suddenly drops, Beijing Jet rig construction contract should check the leakage site, set aside when necessary grouting pipe, check the sealed performance; 2, that there is no risk or intermittent risk pulp slurry When, or the Department of soft soil is considered normal phenomenon, may be appropriate to re-spray; if there are empty, underground passage near the line, you should not upgrade grouting pipe, continue to take slurry grouting until date, or set aside pending the slurry grouting pipe After solidification, re-grouting until take slurry date, using quick-setting slurry, if necessary, to facilitate the solidification in the vicinity of the slurry grouting pipe; 3, take measures to reduce the main reason for the pulp slurry excessive risk, are generally effective range jet injection Pulp incompatible, much more than the Jet grouting slurry consolidation required amount due;
