就静压注浆而言，由于浆液对地层裂隙或孔隙的充塞作用，裂隙或孔隙将逐渐变小，吸浆量也逐渐变低，相应的注浆压力呈递增趋。尤其在不是的注浆深度、不同的岩层条件下，要求采用不同在注浆流量和压力。
As for the static pressure grouting, because of the filling effect of the slurry on the formation fractures or pores, the fractures or pores will gradually become smaller, the amount of slurry suction will gradually become lower, and the corresponding grouting pressure will gradually increase. Especially in the condition of different grouting depth and different rock stratum, different grouting flow and pressure are required.
在双液注浆施工中，为了能准确控制浆液的凝固时间，两液的吸浆量应满足一定的比例关系，要求注浆泵在注浆过程中，能随时调节流量、压力，而且供液要均匀稳定，以满足注浆工艺和保证注浆质量的要求。
In the construction of double liquid grouting, in order to accurately control the setting time of the slurry, the suction volume of the two liquid shall meet a certain proportion relationship, and the grouting pump shall be able to adjust the flow and pressure at any time during the grouting process, and the liquid supply shall be uniform and stable, so as to meet the requirements of the grouting process and ensure the grouting quality.
对于高压旋喷注浆，它是通过泵的作用，把低压吸入的浆液或水，以高压排出，从而使喷嘴处液流压力升高。喷嘴处液流压力愈高，喷射流的破坏力愈大，固结体的尺寸也愈大。因此高压旋喷注浆法要求的泵压要比静压注浆大，一般要求注浆泵额定压力为20～34MPa，额定流量为85L/min左右。
For high-pressure jet grouting, it is through the role of the pump, the low-pressure suction of the slurry or water, high-pressure discharge, so that the liquid flow pressure at the nozzle increases. The higher the liquid pressure at the nozzle, the greater the destructive force of the jet flow and the larger the size of the consolidation body. Therefore, the pump pressure required by the high-pressure rotary grouting method is larger than that required by the static grouting method. Generally, the rated pressure of the grouting pump is 20-34mpa, and the rated flow is about 85L / min.
