[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] High Pressure Injection Method quality standards use high-pressure jet grouting can be checked against the excavation project requirements and local experience, coring (core or soft conventional coring) , standard penetration test, load test or test methods such as injection wells around inspection, and an engineering test, comprehensive evaluation of observational data and the actual results reinforcing effect. 2 test points should be arranged in the following areas: 1) a representative pile location; site of the abnormal situation 2) under its construction; 3) ground situation is complex, grout injection pump, may have an impact on the quality of parts of high pressure jet grouting . 3 Number of test points is 1% of the construction hole number, should not be less than 3:00. 4 Quality Inspection should be in the high-pressure jet grouting carried out after the end 28d. 5 Vertical Bearing Churning Pile Foundation completion and acceptance of, the high pressure injection pump, the bearing capacity test should be used to the tomb complex pile load test and load test. 6 load tests must meet the test conditions in the pile strength, and should be in a pile after 28d. Number of tests is 0.5% to 1% of the total stake, Ninghe injection pump, and every single project should not be less than 3:00. High-speed soft foundation treatment of high pressure spraying pile in with the rapid development of highways, various methods of soft foundation treatment have also developed. Cement CFG referred to high pressure spraying pile, it is in the gravel pile reinforcement developed on the basis of a foundation formed by the addition of cement, fly ash, stone chips and sand-water mixture formed pile high bond strength , and soil between piles, CUSHION together form a composite. Shi Shi fight order to fight the order and spacing of the nature of the soil and the pile about: in soft soil, mortar injection pump, a large pile spacing, can be separated jump play pile construction in saturated loose silts, as pile spacing smaller, the continuous application of playing on Full fabric pile, regardless of the size of the pile spacing, are not from around promoting inward construction should be used to promote the program or from the center outward from one side to the other side to promote the program.
