injection grout pump

Applications of the double-plunger injection system:
Tunneling and underground engineering: Shield tunneling synchronous grouting, pre-support grouting (pipe roofing), and backfill grouting behind tunnel linings; ensures precise control of surface settlement and supports uninterrupted, high-flow continuous operations.
Mining engineering: Underground rock strata water-blocking and reinforcement, and goaf (mined-out area) infill grouting; explosion-proof double-plunger systems operate safely in high-gas environments, significantly reducing the frequency of underground equipment maintenance.
Water conservancy and hydropower engineering: Dam foundation curtain grouting and dam body seepage-proofing/reinforcement; stable high-pressure output ensures grout penetrates fine rock fissures, enhancing the seepage-proof performance of dam foundations.
Specialized engineering: High-pressure jet grouting, precision chemical injection for oil and gas fields, micropile foundation anchoring grouting, and borehole wall stabilization/leak sealing; suitable for a wide range of high-precision, high-pressure injection applications.

A low-wear plunger type grout pump is designed with attention to the components exposed to abrasive grout. For contractors handling cement and bentonite-based mixtures, wear performance affects maintenance frequency, pumping consistency and equipment availability throughout the project.

Grout pumping unit in 20ft container applications: Tunnel Waterproofing: Seal leaks in underground tunnels or subways. Mining Reinforcement: Stabilize mine shafts or stopes with resin injections. Foundation Repair: Fill voids under buildings or bridges. Environmental Projects: Contain pollutants via underground barrier walls.Emergency Repairs: Rapid response to sewer leaks or dam cracks.

An Injection Grout Pump for Underground is a high-performance machine used to inject grout materials into the ground under pressure. These pumps are essential in underground construction, mining, tunneling, and infrastructure projects where ground stabilization, waterproofing, or structural reinforcement is required.

A drilling mud jet grout pump is a specialized high-pressure pumping system designed for dual applications in geotechnical and drilling operations: circulating drilling mud during drilling and injecting grout for soil stabilization or jet grouting. This hybrid system combines the functionalities of traditional drilling mud pumps and jet grouting equipment, making it ideal for scenarios where borehole stabilization and ground improvement are required simultaneously. 

The high-pressure grouting pump uses high-pressure injection technology to inject grouting materials (such as cement slurry, chemical slurry, etc.) into the formation to achieve reinforcement, waterproofing, anti-seepage and other purposes. It has the characteristics of high voltage, high efficiency, and stability, and is one of the indispensable important equipment in modern engineering construction.

Jet grout mixer plant is a specialized equipment used for producing, mixing, and transporting grouting materials. It is widely used in foundation reinforcement, tunnel construction, slope stability, and other fields such as construction, transportation, and water conservancy.

Jet grout pump has important application value in building foundation engineering, especially in situations where underground drilling operations are required to reinforce or repair foundation piles (such as pile foundations).

A 100-bar grout injection pump typically refers to a pump capable of delivering grout (a mixture of cement, water, and sometimes additives) at a pressure of 100 bar.
