The grouting anchor rods are developed based on the actual needs of tunnel engineering, slope treatment projects, coal mine roadway projects, etc. The main products include ordinary hollow grouting anchor rods, self-tapping hollow grouting anchor rods, expansion shell-type hollow grouting anchor rods, extendable grouting anchor rods, combined hollow grouting anchor rods, segmented prestressed hollow anchor rods and sleeve-type prestressed hollow anchor rods.
This technology is applicable to projects such as permanent support of good surrounding rock in geological conditions, as well as advanced support, slope support, and foundation pit support for highways, railways, and tunnels. Through pressure grouting of the hollow anchor rod body, it can consolidate the fractured rock mass, improve the rock mass, block groundwater, and prevent corrosion of the rod body, thereby achieving the goal of excellent support.
