[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] High Pressure Injection Method (Jet Piles) jet grouting pile construction technology is a new development on the basis of the common chemical grouting reinforced soil The method is the use of high pressure water jet excavate rock of a technology. With a high-pressure pump (usually 15-25MPa) the cement-based or water glass slurry through a special nozzle tip drill Nanyang twin jet grouting anchor rig, is injected into the soil at high speed Nanyang twin jet grouting anchor rig, the spray nozzle When the slurry side slowly rotating (20r / min), slowly lift one side (typically 15-30cm / min) high pressure slurry level jet, constantly cutting soil Nanyang twin jet grouting anchor rig, and forcibly cut down soil and slurry mixing, and finally form a continuous accumulation of the mixture into a round circular cylinder condensate within the effective firing range of the ejection force. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] high pressure grouting pile foundation reinforcement construction preparation construction: clean up the site before construction Nanyang twin jet grouting anchor rig, land leveling; marking the location of underground pipelines and underground structures; press Design test put axis, measuring holes put specific and clearly marked to draw floorplan hole pattern, prepared hole number; then excavation circulation tank, mud pools, erection rails, after leveling bench, aligns with a card After starting hole and fixed ready spud.
