As a highly efficient, compaction grout mixing plant has a wide range of application scenarios in multiple engineering fields.
1. Civil engineering field
In the field of civil engineering, compaction grout mixing plant is mainly used for grouting reinforcement of infrastructure such as dams, tunnels, bridges, etc. These projects usually have high requirements for the quality and performance of grouting materials. The compaction grouting mixing station can produce grouting materials that meet the requirements to ensure the stability and safety of the project.
2. Construction engineering field
In the field of construction engineering, compaction grout mixing plant also plays an important role. It can be used for grouting reinforcement and repair of building structures, such as improving the seismic performance of buildings and enhancing the bearing capacity of foundations. In addition, in the construction of high-rise buildings, compaction grouting mixing station can also provide high-quality grouting materials for filling and reinforcing the structural gaps of buildings.
3. Underground engineering field
Underground projects such as subways and underground pipelines have high requirements for waterproofing and stability due to their underground environment. Compaction grout mixing plant can produce grouting materials with excellent waterproof performance, which are used for grouting waterproofing of underground facilities such as subway tunnels and underground pipelines. This helps prevent groundwater leakage and damage to engineering structures, and ensures the safe operation of underground projects.
4. Mining Engineering Field
In mining engineering, compaction grout mixing plant can be used for grouting filling and reinforcement of mine tunnels and mining areas. Through grouting filling, the stability and bearing capacity of mine tunnels can be improved, and mine collapse and accidents can be prevented. At the same time, grouting reinforcement can also enhance the structural stability of mining areas and improve the safety and efficiency of mining operations.

More Grout plant

Injection grout plant (grouting plant/grouting equipment system) is an integrated equipment system for grout preparation and injection in geotechnical engineering, construction and geological disaster management. Its core functions, technical features and application scenarios are as follows:
Core functions and equipment composition
Grout preparation system
Double-shaft mixer: adopts variable frequency speed regulation technology to achieve accurate proportioning of raw materials such as cement, water glass, bentonite, etc. (proportioning accuracy ±1%) to ensure slurry uniformity.
High-speed pulping machine: through the action of centrifugal force (speed ≥1450r/min), the powder is quickly dissolved, and the preparation efficiency is increased by 40% compared with traditional equipment, which is suitable for ultra-fine cement-based slurry.
Automatic batching system: integrated with screw conveyor, electronic scale and PLC controller to realize automatic metering and transportation of raw materials and reduce manual intervention.
High-pressure injection system
Piston pump group: adopts three-cylinder single-acting reciprocating pump (such as SGB6-10 type), with an output pressure of more than 10MPa and a flow rate of 6-10L/s, supporting single-liquid slurry and double-liquid slurry (cement-water glass) injection.
Intelligent control system: real-time monitoring of grouting pressure, flow and cumulative grouting volume, automatic generation of construction records (in compliance with GB/T 50448-2015 specifications), and support for cloud data storage and traceability.
Explosion-proof design: For high-risk environments such as coal mines, the equipment is equipped with explosion-proof motors, intrinsically safe circuits and pressure relief valves to ensure construction safety.
