[0002] Foundation and basic engineering is the key part of building engineering, and the foundation supports the foundation and bears all the loads of the building. The foundation transmits the upper load to the foundation. Its content covers foundation treatment (such as replacement of cushion, dynamic compaction, deep mixing, etc.) and foundation engineering (such as shallow foundation, deep foundation). It is necessary to use a grouting device. In the aspect of reinforcing the foundation, it can fill the voids and cracks of the foundation, improve the strength and stability of the foundation; in the aspect of foundation waterproofing, it can prevent groundwater infiltration and repair foundation leakage; in the aspect of foundation reinforcement, it can remedy foundation defects and improve the adhesion between the foundation and the ground, thereby ensuring the stability and durability of the building and improving the overall engineering quality.

The screw grouting pump is usually driven by a motor to rotate the pump shaft, so that the screw rotates around its own axis and rolls along the inner surface of the liner, thereby forming a sealed chamber between the screw and the liner. With the continuous rotation of the screw, the liquid in the sealed chamber is continuously pushed forward. Every turn, the liquid is pushed forward by one pitch, and is pressed from one sealed chamber to another in a spiral manner, and finally is extruded out of the pump body, realizing continuous delivery of the slurry.
