[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, single and double triple tube anchoring Jet rig, 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, high-pressure jet grouting may affect the quality of the site. 3 Number of test points is 1% of the construction hole number, Cangzhou jet grouting anchor rig, 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 every single project should not be less than 3:00. [Tianjin-strong high-pressure pump Co., Ltd. recommend the star product to your term & 1. High Pressure Injection: the grouting pipe drilled into the soil or into the future, allowing the spray nozzles 20 ~ 40Mpa high-pressure jet stream damage to the foundation soil, slope private jet grouting anchor rig, a space of a predetermined shape, injected The slurry will be washed down soil replacement or partially mixed cemented consolidation body, in order to achieve a method of transformation of soil. 2. Complex Spray: for a period of one grouting holes were more than twice or twice spray job
