[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) foundation complicated, high pressure jet grouting pile driver, may have an impact on the quality of High Pressure Injection site. 3 Number of test points is 1% of the construction hole number, Cangzhou jet grouting pile, and 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 carrying 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 and spin - sprayed pile price, and each single project should not be less than 3:00. [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.
