grout injection station

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.

The main applications of cement grout pump stations include:
Foundation reinforcement: Grouting for foundations in dams, tunnels, mines, etc., to improve bearing capacity.
Structural repair: Reinforcement of buildings and bridges, foundation lifting, soil compaction grouting, etc.
Underground engineering: Tunnel lining, contact grouting, and tunnel waterproofing.
Marine engineering: Underwater foundations, wharf scour protection, shoreline reinforcement, etc.

The grout pump and mixing station is an integrated device combining a mixer, mixing tank, and grouting pump. It injects cement-based or chemical grout into strata, structural fissures, or soil and rock masses under high pressure to achieve reinforcement, seepage prevention, or filling functions. Its working principle can be divided into three stages:
1. Cement grout preparation: A high-speed vortex mixer rapidly mixes cement, bentonite, and water, forming a homogeneous grout within 10 seconds, preventing particle sedimentation.
2. Cement grout storage: The mixing tank continuously agitates the grout to prevent solidification and ensure a continuous supply.
3. High-pressure grouting: A hydraulically driven pump generates high pressure through piston or plunger movement, injecting the grout into the target area. The pressure range is 0-45 Bar (some models reach 0-100 Bar), and the flow rate is 0-100 L/min.
