The XQV LGB-3 screw grouting pump is suitable for medium‑resistance grouting. It handles a wide range of materials including cement mortar (sand ≤3–5 mm), micro‑expansive cement slurry, and cement‑sodium silicate two‑component mixtures.
Typical applications include:
- Bridge & Precast Components: Prestressed pipeline grouting for precast bridges (≤50 m, long or curved ducts).
- Tunnel Engineering: Filling gaps between tunnel secondary lining and surrounding rock (deep or irregular voids); initial tunnel support gap grouting with fine sand (≤3 mm).
- High‑Speed Rail: Track slab grouting requiring high compactness.
- Building Construction: Post‑cast strip filling with micro‑expansive slurry for anti‑cracking.
- Bridge Bearings: Continuous injection grouting to avoid air entrapment.
- Underground Pipe Gallery: Sealing with viscous grout to prevent loss.
- Dam & Foundation: Crack repair for dams; small to medium foundation reinforcement (e.g., soft soil cement mixing piles).
The pump ensures grout penetrates tiny gaps, reduces voids, and maintains stable, pulse‑free flow even under varying viscosity conditions.
