[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, Shunyi bolt rig, shall adopt 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. Dual pipe high pressure rotary jet pile is carried out in a modified Jet Pile on the basis of the original product, export bolt rig, it has a pile speed, vertical high, simple operation, Hubei roofbolter other accessories fewer features, is the soft ground treatment, curtain sealing, anti reservoir piping, drain only ideal for construction equipment. 1, the main purpose twin-tube high-pressure jet grouting pile is mainly used in soft ground treatment of large ports, sealing curtain and water conservancy. 2, the main features twin-tube high-pressure jet grouting pile in case of external conditions permit, the general construction method a shot in the end, the electric bolt rig, so you can increase the speed of construction, but also improve the quality of pile, can also There are obstacles on the field of the construction site.
