Jet Grouting Method Jet Grouting Pump Equipment
The Jet Grouting Pump is a critical component of the jet grouting system, responsible for delivering the grout under high pressure. The pump must be capable of generating pressures in the range of 20-50 MPa to ensure effective soil erosion and grout penetration. The pump should allow for precise control of the grout flow rate to match the specific requirements of the project (e.g., soil type, desired column diameter).
Jet Grouting Method is an advanced foundation treatment technology that injects cement slurry into the ground through a high-pressure jet stream to improve soil properties or form a reinforcement body. This method is particularly suitable for deep foundation treatment in urban environments, tunnel engineering, waterproofing and reinforcement of the bottom of buildings, etc. It can generate pressures up to 500 bar or even higher to ensure that the slurry can penetrate various types of soil, including sand, clay and soft rock. It supports single-tube, double-tube or triple-tube jetting technology. The single-tube system is mainly used for shallow soil improvement; the double-tube system adds air injection to increase the diffusion range of the slurry; and the triple-tube system combines water, air and slurry injection, which is suitable for more complex geological conditions.


Jet grouting method jet grouting pump equipment applications:
Foundation Underpinning: Strengthening existing foundations or correcting settlement issues.
Excavation Support: Creating cutoff walls or ground anchors to stabilize excavation pits.
Seepage Control: Reducing groundwater infiltration in dams, levees, or tunnels.
Liquefaction Mitigation: Improving the seismic performance of loose, sandy soils.


Choosing the right jet grouting pump equipment is essential to ensure project quality. It is necessary to comprehensively consider the specific needs of the project, such as geological conditions, expected reinforcement effects, and budget constraints, to determine the most suitable equipment model and technical parameters.
