Due to its high pressure spraying pile construction equipment is simple, convenient, fast, less environmental pollution and low prices, it has a very good application and development prospects in construction projects. But our high pressure jet grouting technique is not long, spin Roofbolter spray equipment, lack of practical experience, technical data are not comprehensive, with normative standards imperfect, Jet bolt rig parameters, thus there are more accidents and quality construction material waste serious phenomenon. But our engineering Application of high pressure spraying pile more than 20 years, the quality of the pile acceptance testing process also accumulated a lot of testing data, according to statistics computational scientific approach can objectively reflect the high pressure spraying pile. [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, Tanggu Jet Roofbolter, may have an impact on the quality of high-pressure jet grouting site. 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 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.
