Due to its high pressure spraying pile construction equipment is simple, convenient, fast, less environmental pollution and low prices Panjin triple tube Churning Pile, and therefore has a good application prospects in engineering construction. But our high pressure jet grouting The technology is not long, lack of practical experience, technical data are not comprehensive, with imperfect normative standards, thus there are more accidents and quality construction material waste serious phenomenon, but the application of high pressure spraying pile engineering 20 years Panjin triple tube rotary jet pile, the pile quality 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] stirred slurry formulation of this project Churning Pile grout slurry using water-cement ratio of 1.0. Cement to screening, and in order to prevent the grout segregation Panjin triple tube Churning Pile, you should keep stirring the mortar machine. In order to ensure concentration of slurry should be used secondary mixing the slurry preparation, ie to determine the water-cement ratio of cement slurry formulation and stirred in a blender. Stirring 3-5 minutes into the second mixing bucket use only. Prohibiting the use of a mixing bucket, while with pulp while pumping slurry, it would be difficult to control water cement ratio. Cement 320Kg / m.
