The dam foundation grouting equipment is first used to prepare the grouting materials. Grouting materials usually include cement, water, admixtures, etc., which need to be mixed in a certain proportion. By using efficient grouting equipment, the uniform mixing of grouting materials can be ensured to meet the construction requirements.

Grouting system layout
In the dam foundation grouting construction, the layout of the grouting system is crucial. The grouting system includes components such as grouting pumps, grouting pipes, and grouting holes. The dam foundation grouting equipment needs to be accurately installed and debugged according to the layout requirements of the grouting system to ensure the smooth progress of the grouting process.

Grouting construction operation
Grouting pressure control: The dam foundation grouting equipment needs to be able to accurately control the grouting pressure to meet the requirements under different construction conditions. By adjusting the pressure parameters of the grouting equipment, it can be ensured that the grouting materials can be evenly and stably injected into the dam foundation.
Grouting speed adjustment: Grouting speed is one of the important factors affecting the grouting quality. The dam foundation grouting equipment needs to have the function of adjusting the grouting speed to meet the needs of different grouting stages and grouting materials. By reasonably adjusting the grouting speed, the continuity and stability of the grouting process can be ensured.
Grouting parameter recording: During the grouting process, various grouting parameters need to be recorded, such as grouting pressure, grouting speed, grouting volume, etc. Dam foundation grouting equipment is usually equipped with equipment such as grouting automatic recorders to record grouting parameters in real time and provide data support for construction quality control.

Construction quality control
Dam foundation grouting equipment plays an important role in construction quality control. By accurately controlling the grouting pressure, grouting speed and grouting parameters, the effective injection of grouting materials and the uniform reinforcement of the dam foundation can be ensured. At the same time, the dam foundation grouting equipment can also cooperate with other quality inspection methods, such as drilling coring, water pressure testing, etc., to comprehensively inspect and control the grouting quality.

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.
