High pressure spraying pile construction quality control measures: material selection and construction quality control parameters 1, grouting the curing agent and an admixture varieties, specifications and performance should be consistent with the design. 2, cement before use jet grouting rig for qualification stirred slurry of water used should be consistent with "concrete mixing water standards." 3, in order to understand the nature and reasonable formula jet grouting slurry body must take soil samples on-site layers, indoors and with different water content ratio test, preferably the most reasonable slurry formulation. Before the formal construction site injection test to identify jet diameter and strength of solidification body to verify the reliability and safety of the design. Jet grouting method of reliability with high-pressure jet grouting up 20 ~ 40MPa pressure, the energy of the impact damage to the soil very giant sand on the viscosity and can be blanked damage. Any high-pressure water jets can be impulsive soil soil particles, can be high-pressure jet grouting rig Jet track, as long as the correct order of construction, the use of high-quality cement grouting material injection technology and the use of appropriate and reasonable design parameters, namely obtain excellent foundation reinforcement and seepage curtain wall. High reliability solidification body. High Pressure Injection pressure jet force is greater destruction of soil, the effective destruction of the distance, to be hardened grout and soil particles that form a consolidated body. Consolidation body diameter (length) by the soil affect concave appearance was irregular, hard soil consolidation diameter (length) to be smaller, high-pressure jet grouting of integrity, uniformity are higher than normal static pressure grouting. In addition, consolidation body in excellent (no concrete erosion) environment, the intensity increased, the rate of increase continued strength to more than 10 years. Measured increase by 1.5 times and even 10 years later. Therefore, as long as no concrete erosion in groundwater and not cold (ie freezing temperature not lower than minus 200C) conditions, body mass consolidation reliable and can be used as a permanent foundation and seepage curtain.
