It is widely used for pressure grouting, including anchor grouting, backfill grouting, consolidation grouting in highway, railway, tunnel, subway, hydropower station, underground chambers, dam, slope, soft rock. In addition, it can also be applied in spraying protection of interior and exterior walls, building surface of civil engineering.
1. Compact structure and reliable performance.
2. SJB-20B has the function of mixing and grouting can be completed synchronously by one machine .
3. Large range of water cement ratio: thick mortar in high concentration is also workable.
4. Continuous grouting avoids instantaneous high pulsation produced by pumping work.
5. Grouting pressure will be released when getting setting pressure.
6. Equipped with air compressor and spray gun, it can be used for spraying protection of interior and exterior walls, building surface of civil engineering
