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.
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.
A hydraulic high-pressure horizontal cement grouting pump is a specialized device driven by a hydraulic system to inject cement slurry and other readily setting materials into rock formations, soil cracks, or gaps in building structures at high pressure. The core principle is based on hydraulic transmission and the reciprocating motion of a plunger: Hydraulic drive: An electric motor drives a gear pump, which delivers high-pressure oil through a relief valve and into a hydraulic reversing valve block, controlling the reciprocating motion of the hydraulic cylinder. Synchronized grouting: The hydraulic cylinder and the working cylinder move synchronously, with suction and discharge valves at each end. This allows for single-liquid or dual-liquid grouting (e.g., a mixture of cement slurry and water glass).
