XQV Foundation Pit Parts – Prestressed Anchoring Solutions for Deep Excavation Support
Reliable Anchor Systems for Soil Nailing, Tie‑Backs & Strut Excavation
XQV manufactures and supplies a complete range of high-performance special accessories for prestressed foundation pit support systems. These components are the critical backbone of modern deep excavation engineering, ensuring structural stability, load transfer efficiency and long-term safety.
Our product line is engineered to meet the demanding requirements of various geotechnical applications, including slope stabilization, deep foundation pit support, tunnel lining and underground construction. Each component is manufactured from premium-grade materials, treated with advanced anti‑corrosion technology and tested to international standards.
Compared with conventional rigid support methods, the prestressed anchoring system offers:
- Active load control – Prestress is actively applied to control deformation before it occurs.
- Material savings – Reduced steel and concrete usage lowers overall project costs.
- Fast installation – Simplified on‑site assembly improves construction efficiency.
🔧 High Anchorage Efficiency
ηa ≥ 95%, ensuring reliable load transfer from the anchor head to the ground.
🛡️ Corrosion Protection
Hot‑dip galvanised or coated with advanced anti‑corrosion finishes for long‑term durability in aggressive soils.
⚙️ Wide Adaptability
Suitable for various foundation pit conditions – soft soil, rock, mixed ground and high‑water‑table areas.
📏 Precision Control
Accurate tensioning via calibrated hydraulic jacks ensures consistent prestress application per design requirements.
🏗️ Cost‑Effective
Reduces material consumption and construction time, delivering excellent return on investment.
| Component (中文/英文) | Function Description |
|---|---|
| Anchor Head / Anchor Plate (锚头 / 锚垫板) | Receives the prestressing force and transfers it to the bearing plate and the retaining structure. Made from high-strength cast steel or Q345 steel plate. |
| Anchor Rod / Steel Strand (锚筋 / 钢绞线) | The core tension element, typically 7‑wire low‑relaxation steel strand (φ15.2 mm), embedded into the grouted borehole to carry the tensile load. |
| Anchor Wedge / Clip (夹片) | Locks the steel strand into the anchor head; self‑locking wedge design ensures no slippage under sustained tension. |
| Guide Cap / Trumpet (导向帽 / 喇叭管) | Attached to the end of the anchor rod to facilitate smooth borehole entry and centering during installation. |
| Extrusion Sleeve (挤压套) | Mechanically anchored onto the strand via a hydraulic extruder (GYJ series) for P‑type dead‑end anchor applications. |
| Isolation Bracket / Centralizer (隔离支架 / 对中器) | Keeps the anchor rod centered inside the borehole, ensuring uniform grout cover and corrosion protection. |
| Load‑Bearing Body (承载体) | Transfer the tensile load from the strand to the grouted anchor body, commonly used in pressure‑type anchor systems. |
| Top Plate / Bearing Plate (顶板 / 承压板) | Distributes the concentrated anchor force over a larger area of the concrete surface, preventing local crushing. |
| Spiral Reinforcement (Helix) (螺旋筋) | Reinforces the concrete behind the anchor head to resist bursting stress and enhances anchorage zone capacity. |
| Coupler / Connector (连接器) | Joins two lengths of anchor rods or steel strands to achieve the required tendon length for deep rock/soil layers. |
- Deep Foundation Pit Retaining Walls – Prestressed ground anchors and soil nails for deep excavation support in urban areas.
- Slope Stabilisation & Landslide Remediation – Permanent anchor systems for highway cuttings, railway embankments and open-pit mines.
- Underground Structures – Tunnel portals, cut‑and‑cover tunnels and underground parking structures.
- Bridge Abutment & Pier Foundations – Anchor tie‑back systems for large bridge foundations and abutments.
- Water Conservancy Projects – Dam foundation anchoring and lock chamber wall reinforcement.
