Automatic grouting equipment for tunnel subway engineering

High-pressure grouting is a technology that uses hydraulic, pneumatic or electrochemical principles to uniformly inject slurry (usually cement slurry, water glass slurry, chemical slurry, special new materials, etc.) into the formation, surrounding rock, backfill or lining through a grouting pipe. Under high pressure, the slurry will penetrate along the cracks and pores of the soil layer, remove moisture and air from the soil particles or rock cracks, and form slurry veins. With the continuous injection of slurry, the slurry veins gradually expand and eventually form a continuous reinforcement belt or stone body. The grouting pump station can help us achieve this goal very well. The grouting pump station is a special equipment for high-pressure grouting operations. It is widely used in underground engineering, tunnels, mines, water conservancy, geological disaster management and other fields. It injects slurry into the formation, cracks or structures through a high-pressure pump to achieve the purpose of reinforcement, water stopping, filling or sealing.
The main components of grouting equipment for tunnel subway engineering:
1. High-pressure grouting pump
- The core component is responsible for pressurizing the slurry and transporting it to the grouting point.
- Common types: plunger pump, screw pump, diaphragm pump, etc.
- Working pressure is usually 1-50 MPa, or even higher.
2. Mixing system
- Used to mix slurry to ensure slurry uniformity.
- Includes mixer and slurry storage barrel.
3. Control system
- Used to adjust pumping pressure, flow and grouting volume.
- Can be manual control or automatic control system.
4. Pipeline system
- Includes high-pressure hose, grouting pipe and joints for conveying slurry.
- Must be resistant to high pressure and corrosion.
5. Auxiliary equipment
- Such as pressure gauge, flow meter, safety valve, etc., used to monitor and ensure safe operation of equipment.
Our company's GGP400/1000/95/165DPL-E/A Automatic grouting equipment for tunnel subway engineering uses double cylinders piston pump with single acting to ensure the continuous slurry flowing (small pulse) and not easily leaking compared with the double acting piston pump. The pressure and displacement are: 40bar@80L/min; 100bar@40L/min, Grouting pressure and displacement are adjustable.
In addition, there are many types of automatic grouting equipment produced by our company:
1. Classification by power source
- Electric grouting pump station: suitable for occasions with stable power supply.
- Diesel grouting pump station: suitable for no power supply or field operations.
2. Classification by purpose
- Geological grouting pump station: used for underground engineering, mining, etc.
- Construction grouting pump station: used for foundation reinforcement, tunnel construction, etc.
- Hydraulic grouting pump station: used for water conservancy facilities such as dams and embankments.
3. Classification by slurry type
- Cement slurry grouting pump station: suitable for cement-based slurry.
- Chemical slurry grouting pump station: suitable for chemical slurry (such as epoxy resin, polyurethane).
1. Tunnels and underground engineering
- Advance grouting and surrounding rock reinforcement in tunnel excavation.
- Water stopping and filling in subway construction.
2. Mining engineering
- Mine support, crack filling, reinforcement of loose rock mass.
3. Water conservancy engineering
- Anti-seepage treatment and reinforcement of dams and embankments.
4. Construction engineering
- Foundation reinforcement, pile foundation grouting, crack repair.
5. Geological disaster control
- Reinforcement and control of landslides and collapses.
