Grouting equipment

The cement grout pump for grouting underground is the key equipment in the grouting construction. The performance and quality of the rout pump for grouting underground plays a decisive role in the safety, quality and efficiency of the grouting project. If the choice of cement grout pump for underground is blind and arbitrary, it may cost a relatively large price and fail to achieve the expected results, or even cause engineering accidents. It should be taken as a warning and improved scientifically. The cement grout pump for grouting underground has the advantages of low energy consumption, low vibration, low noise, small size, high efficiency, stable and reliable performance, convenient pressure and flow adjustment, and long service life. The maximum pressure of the pump can be set; unnecessary losses during the grouting process can be avoided; the grouting method is to hydraulically press the grout into the cracks of the rock or soil layer and fill it up and compact, and new crack

Gaodetec is a high-tech and modern enterprise specializing in the research, development and manufacturing of grouting machine . The type of high pressure grout injection pump machines include hydraulic high-pressure grouting pumps, piston grouting pumps and peristaltic pumps. We have a professional R&D team and our own equipment production site, which can provide customized services according to customer needs. We next introduce is the piston grouting pump of the injection machine for sale.                       The working principle of the high pressure grout injection pump : when the piston is pushed out in the reciprocating motion of the piston pump, the outlet test door is closed by its own weight and pressure difference, and the inlet door is tested by the pressure difference. Fill the pump chamber with liquid. When the piston opens the pressure inward, the pressure in the pump chamber increases, causing the inlet check valve to close, the outlet check valve to open, and flu

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
