[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 bucket, 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] High Pressure Jet Grouting Jet Grouting Pile: takes advantage of the high-pressure pump cement slurry through a special nozzle tip drill a single liquid injection pump, in order to High-speed horizontal spray buried body Matsubara injection pump, with the impact of cutting liquid soil, and drill one side at a constant speed (20r / min) rotation, one side low (15 ~ 30cm / min) gently lift the new injection pump so that the soil thoroughly mixed with the grout solidified to form a cylindrical body with a certain intensity of consolidation (0.5 ~ 8.0MPa) (ie jet grouting pile), allowing the foundation to get reinforcement. Features rotating pile are: to improve the shear strength of the foundation; can use small-diameter drill hole rotary jet to be larger than 8 to 10 times as large diameter concretion body, it can be used without disturbing the existing buildings near the foundation reinforcement Construction noise and vibration small;; soil can be used for any soft soil slurry injection pump can be controlled reinforcement range; equipment is relatively simple, lightweight, high degree of mechanization; vast source material, construction is simple, fast, and low cost.
