Cementitious grouting equipment and machinery
The cementitious grouting equipment and machinery preferably has the characteristic of automatically adjusting the grouting volume as the grouting pressure changes.
The cementitious grouting equipment and machinery should have a larger displacement adjustment range. Generally, the final volume of grouting and the initial volume of grouting change 8-10 times. Facts have proved that a small amount of grouting is conducive to compaction.
The cementitious grouting equipment and machinery should have reliable pressure control capability. Since grouting “filling and compaction” will inevitably result in overpressure of the grouting pump, the pump should reduce the amount of slurry in time to reduce the flow resistance of the slurry in the gap, so as to avoid grouting and fracturing, mechanical accidents, etc.
