[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] high pressure jet grouting applied to silt, silty soil, the flow of plastic soft plastic or plastic clay, silt, sand, loess, plain fill and crushed Foundation stone such as soil reinforcement. Can be used for both ground handling buildings and new buildings, deep excavation retaining or retaining the side wall, the bottom of the pit to prevent piping and reinforcement anchor uplift crawler rigs, dam reinforcement and water curtain and other projects. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] high pressure grouting pile foundation reinforcement construction of high pressure slurry pump slurry feed: open the high-pressure pump Jilin anchor rig, slurry feed slowly until everything is normal hydraulic anchor rig to bore, stable pump pressure and pump capacity, and in situ rotation spraying 30 seconds, the slurry can fully meet the bottom of the hole. Gunite rotation Improvement: After confirming stable slurry reaches the bottom of the hole pump pressure, pump volume, and start rotating lifting the nozzle rotation speed control in 18-20r / min, to enhance the speed control in 20-30㎝ / min hydraulic anchor bolt rig , adjusting the parameters in case of changes in the formation. Take slurry recharge: High jet construction process should be carefully observed changes in the amount of oozing slurry, when the amount of abnormal plasma should take good record and look for reasons, Jet has been completed in time to fill the hole until the pulp slurry surface is no longer under Shen. Acceptance Visa: When the acceptance qualified after the above work is completed before entering the work under a pile of construction. Construction sequence: Churning Pile should pile position surrounding the construction sequence, after the central portion of the hole.
