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, with high-pressure equipment so as soft foundation consolidation agent slurry or water become more 20mpa high-pressure jet ejected from a nozzle, Chengde sealing curtain rigs, impact damage weak foundation soil, and with the active pipe rotation and promotion, driven at a constant speed of rotation grouting pipe and upward, forced mixing the slurry with the soil particles, a mixture of slurry and soil particles to be hardened after condensation to form a high strength, low compression of the soil complex. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] construction construction Churning Pile requirements Churning Pile is the use of Jet grouting rig will drill pipe and placed pile bottom nozzle design elevation, the previously prepared slurry through high voltage generator so with great energy flow after grouting pipe from the nozzle side of the high-speed jet, forming an energy highly concentrated flow, direct damage to the soil, the injection process, while rotating the drill pipe upgrade, make The slurry thoroughly mixed with the soil, sealing curtain rig latest offer, a certain diameter columnar consolidation body in the soil, sealing curtain rig manufacturer, so that the foundation to achieve reinforcement. Construction work is generally divided into two processes, that is, after the first diamond spray, then drill jet, then lift stirring to ensure the proportion of pulp per meter pile and soil quality. Before construction site leveling, using prime soil roadbed filler (both sides of the embankment, sidewalks and a range of non-motorized traffic lane filling clay). First performed experimental pile construction, sealing curtain rig models before construction, to determine the appropriate concentration of slurry, spray volume, spray pressure, spraying process parameters to enhance the speed of construction, provide the basis for the formal construction, the number of test piles not less than five.
