There are many and complex factors that can influence the grouting pressure, but they can be summarized in three aspects: grouting machine, grouting materials and the proprieties of strata [3].
And the grouting pressure formed by cement grout is higher than that formed by polymer chemical grout; the effects of grouting pumps, grouting materials and conditions of rock mass on the grouting pressure are the result of interaction of the three but not purely the power of grouting pumps; however, the references just qualitatively explains the factors influencing the grouting pressure and the law of grouting pressure variation, failing to draw the physical relationship between grouting pumps, grouting materials and proprieties of rock mass.
To get an ideal grouting effect in the case of grouting the same material in the rock with poor groutability, we can use the grouting pump whose flow rate is low or reduce the flow of grouting pump
