Grouting equipment

The characteristics of soil nailing wall support are: combining soil with low tensile strength with grouting reinforcement.                              Composite, through the deformation of the soil, makes the contact surface produce binding force and friction force, promotes the steel bar to be pulled, plays a joint role, and improves the stability and bearing capacity of the soil. This kind of composite also enhances the ductility of soil failure, which is conducive to safe construction; The displacement of soil composite wall is small, which is generally tested 20mm; Simple equipment, short length of soil nail, simple drilling and grouting process; Good economic benefit and easy popularization; Good coordination with excavated earthwork and implementation of flow operation can shorten the construction period.                            Grout injection pump for rock bolts soil nails should be used in this project, and small, movable and reliable grout injection pump for rock bolts
