vertical grout pump

A vertical injection grout pump is a high-pressure grouting device specifically designed for vertical grouting operations. Its core function is to precisely inject grout (such as cement grout, chemical grout, etc.) into foundations, soil layers, or building cracks using high pressure to achieve engineering purposes such as reinforcement, seepage prevention, and leak sealing.

High-pressure grouting pumps, based on high-pressure jet grouting technology, are used in drilling rig applications to achieve foundation reinforcement through the coordinated operation of the high-pressure pump and the drilling rig.

Grouting pumps inject cement-based or chemical grout into foundation cracks, pores, or weak layers under high pressure, forming a solidified mass to enhance the foundation’s bearing capacity. Its reinforcement principles encompass the following aspects:
Permeation consolidation: The grout fills soil pores, increasing density through cementation; suitable for highly permeable strata such as sandy soil and silt.
Fracturing reinforcement: High-pressure grout fractures the soil, forming a dendritic grout vein network, improving the overall strength of the foundation; commonly used for soft clay or collapsible loess.
Compaction grouting: High-pressure compaction of the surrounding soil creates a dense zone; suitable for saturated soft clay or artificial fill.

A high-pressure cement grouting pump is an industrial device that delivers cement grout (or chemical grout) under high pressure. It is widely used in engineering fields such as foundation reinforcement, seepage prevention and plugging, and structural reinforcement. Its core function is to inject grout under high pressure to fill voids in soil or concrete structures, forming a stable composite structure and improving the load-bearing capacity and durability of the project.

A high-pressure vertical grout pump is a specialized positive displacement pump designed to inject grout (a mixture of cement, water, and often additives) into cracks, voids, and fissures under high pressure. Applications: Soil nailing & ground stabilization. Tunneling and mining grouting. Dam and foundation repair. Post-tensioning duct grouting. Void filling beneath slabs or structures.
