The grout injection plant for dam grouting is an integrated system designed for cement grout preparation, continuous agitation and controlled pressure injection during dam foundation construction and rehabilitation.

A complete plant can combine a high-shear grout mixer, storage agitator, hydraulic grout pump, control panel and optional measuring instruments on one compact platform. This arrangement provides a continuous process from grout preparation to borehole injection.

Cement, water and approved additives are introduced into the mixing unit according to the selected grout formulation. The intensive mixing action helps disperse cement particles and produce a uniform, pumpable slurry. After mixing, the grout is transferred to the agitator, where continuous circulation helps maintain consistency before injection.

The grout pump delivers the prepared slurry into drilled holes, rock joints, fractures and foundation voids at the required flow and pressure. The equipment can be used for curtain grouting, consolidation grouting, blanket grouting, contact grouting and remedial injection work.

Typical applications include embankment dams, concrete dams, dam abutments, grouting galleries, spillway foundations, outlet structures and hydropower projects. Mixer capacity, pump flow, maximum pressure, power source and monitoring configuration can be selected according to the geological conditions and grouting program. Gaodetec GGP400/700/100PI-D diesel engine drive grout injection plant was used in Jordan for dam foundation and curtain grouting. The grout injection plant can be used for:

1. Dam foundation curtain grouting
2. Blanket and consolidation grouting
3. Dam abutment rock grouting
4. Foundation contact grouting
5. Deep fracture injection
6. Dam foundation seepage treatment
7. Grouting from inspection galleries
8. Spillway foundation grouting
9. Outlet works foundation treatment
10. Hydropower station foundation grouting
11. Existing dam rehabilitation
12. Remedial and secondary grouting
13. Rock foundation strengthening
14. Foundation void filling
15. Leakage-control grouting

The grout injection plant with following advantages:
1. Compact size, It is combination of mixer, agitator and hydraulic plunger grout pump in one base frame;
2. Have low pressure and high pressure, stepless speed regulation;
3. Yuken relief valve and directional valve for hydraulic system of grout pump;
4. Butterfly valve of mixer and agitator;
5. Oil temperature gauge can automatically control cooler fan working in normal temperature range, if temperature is too high, the machine will stop work automatically;
6. Full hydraulic drive, diesel engine
7. Operation and maintenance are simple.

Working process of grout injection plant for dam foundation and curtain grouting:
The required quantities of water, cement and additives are loaded into the grout mixer. After the selected mixing cycle is completed, the prepared slurry is discharged into the agitation tank.
The agitator keeps the grout moving while the injection pump draws material from the tank and delivers it to the grouting manifold or borehole. Pump flow and pressure can be adjusted according to the injection stage and the response of the foundation rock.
For projects using several grout mixes, the operator can modify the water-cement ratio as required by the approved grouting procedure. Optional monitoring instruments can record injection pressure, flow rate and grout volume for construction control and reporting.

The most important is the type grout injection plant be divide into two parts: grout pump with hydraulic power unit, grout mixer and agitator. And in this design it is more convenient for transport, when two parts were connect together as one whole grout injection plant.
