Injecting is using pressure to make could consolidated slurry inject geotechnical cracks or cracks in the building by boring, then improve its physical mechanics performance, injecting also was known as grouting in water conservancy and hydropower.
1. Seepage control: reduce the permeability of rock and soil, eliminate or reduce the osmotic quantity under water, reduce the engineering stress and pore water pressure, Improve the ability of rock and soil resistance seepage deformation. Such as engineering dam, abutment and dam grouting anti-seepage treatment.
2. Water plugging: truncation water flow, improve engineering construction and operation condition. Such as water leaking of leaking for well wall and other underground engineering.
3. The consolidation: to improve soil or the mechanical properties of structure, recovery its integrity.
4. To prevent landslide: improving geotechnical slope sliding resistance.
5. To reduce surface subsidence: reduce or homogenize the compressibility of rock and soil, improve its inhomogeneity.
6. Improve the foundation bearing capacity: increase the strength of the geotechnical mechanics.
7. Backfill: filling hollow structure, rock and soil mass crack, prevent collapse, improve the mechanical condition of structure
8. Reinforcement: recover structure integrity and mechanical properties.
