High pressure grouting injection machine for drilled anchors
Our high pressure grouting injection machine integrates a high-speed mixer, a low-speed grout storage and mixing tank, and a grouting pump onto a single platform, enabling continuous operation from grout preparation to injection. This high pressure grouting injection machine can switch between high-pressure, low-flow and low-pressure, high-flow modes depending on site conditions, adapting to the grouting requirements of different strata and anchor types. The compact design makes it suitable for operation in confined spaces such as tunnels and underground workings.
In the field of geotechnical anchoring, high-pressure grouting is a core process that determines the load-bearing capacity and durability of anchor bolts. Whether for deep excavation shoring, slope stabilisation, tunnel rock mass stabilisation or foundation treatment in hydropower projects, the quality of grouting directly affects the safety and service life of the structural works.

As the geological conditions, anchor specifications and construction environments vary from one project to another, standardised grouting equipment often fails to perfectly suit all operating conditions. An experienced equipment manufacturer can provide comprehensive customisation services, ranging from mixing tank capacity, pumping flow rate and pressure range to the power source (electric or diesel).
For example:
1.Sandy soil layers require higher grouting pressure to mitigate the risk of borehole collapse; a high pressure grouting injection machine can be customised.
2.Where construction space is limited within tunnels, a compact, modular split-type grouting injection machine can be customised.
3.For remote sites with limited access to electricity, a diesel-powered grouting injection machine can be selected.

Our company specialises in the research, development and manufacture of high pressure grouting injection machines and complete anchoring equipment sets. Our products are widely used in projects such as anchor grouting, consolidation grouting and backfill grouting across sectors including roads, railways, underground railways, hydropower and mining. We can tailor grouting solutions to your specific project requirements, providing end-to-end services ranging from equipment selection and on-site commissioning to operator training.
