[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, 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 drum electric high-pressure injection pump, while with pulp while pumping slurry, it would be difficult to control water cement ratio. Cement 320Kg / m. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] cement mixing pile deep cement mixing pile high pressure injection pump manufacturers, suitable for the treatment normally consolidated silt and silty soil, plain fill, silt, clay soil and groundwater free flow of sand and other loose soil. Reinforcement depth is generally greater than 5.0m. During the construction method, according to the state of the use of reinforcing material selected public good high-pressure injection pump can be divided into the slurry mixing method (wet, that the present rules of deep water slurry mixing method) and powder mixing method (dry method) of two construction type. According to the site engineering geological conditions and superstructure load requirements and the stress state of cement soil pile, cement deep mixing pile plus solid form, can be used as envelope excavation retaining wall, seepage curtain; composite foundation bearing the vertical; bulk cement stabilized soil.
