Anchor injection grout plant is a grouting system specially used for anchor construction. After the cement, water, additives and other raw materials are mixed evenly, the grouting material is injected into the anchor hole through a high-pressure grouting pump, so that the grouting body is closely combined with the anchor rod body and the rock and soil body, thereby improving the tensile strength of the anchor rod. pull-out force and load-carrying capacity.

Anchor injection grout plant is widely used in various geotechnical engineering fields, such as tunnels, subways, slope support, foundation pit support, etc. In these projects, anchor grouting equipment can significantly improve the anchoring effect of the anchor and enhance the stability and load-bearing capacity of the rock and soil mass.

The working principle of anchor injection grout plant is as follows:
First, add cement, water, additives and other raw materials into raw material storage tanks respectively.
The amount of each material is then accurately metered through a control system and fed into the mixing system.
In the mixing system, the raw materials are fully stirred and mixed evenly to form grouting materials that meet the requirements.
Then, the grouting material is sent to the high-pressure grouting pump and injected into the anchor hole through the grouting pipeline.
During the grouting process, the control system monitors and adjusts grouting pressure, grouting speed and other parameters in real time to ensure grouting quality and safety.

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.
