Special Structure & Strengthening Solution
Applications
1. External Post-Tensioning for Bridge Strengthening
External tendons installed outside the existing concrete section to increase load capacity and extend service life — ideal for aging bridges with increased traffic demands.
2. Storage Tanks & Containment Structures
Circumferential and vertical prestressing for concrete tanks, silos, and containment vessels — ensuring liquid-tight integrity and resisting internal pressure.
3. Nuclear Containment Vessels
High-reliability post-tensioning systems for nuclear power plant containment structures — designed to meet strict safety and regulatory requirements for long-term performance.
4. Offshore & Marine Structures
Corrosion-resistant prestressing systems for offshore platforms, jetties, and marine structures — engineered for harsh environmental conditions and long service life.
5. Architectural & Complex Structures
Post-tensioning enables elegant, slender architectural forms — curved roofs, pedestrian bridges, and complex geometries that would not be feasible with conventional reinforcement.
Core Product Range
External Post-Tensioning Systems
External tendons with corrosion-protected strands, anchorages, and deviation saddles — designed for bridge strengthening and structural rehabilitation. Fully grouted or greased-and-sheathed options available.
Epoxy-coated · GroutedMono-Strand Jacks
Lightweight single-strand post-tensioning jacks for external tendon installation and structural strengthening. Ideal for confined spaces and incremental tensioning operations.
Portable · High precisionSpecial Anchorage Systems
Custom anchorage solutions for special applications — including flush-mounted anchors, couplers, and corrosion-resistant anchorage components meeting project-specific requirements.
ASTM A416 · BS 5896Why Choose XQV for Special Structures & Strengthening
Experience in structural rehabilitation for bridges, tanks, and containment structures — with systems designed for long-term durability.
Full range of corrosion protection options — including grouted, greased-and-sheathed, and epoxy-coated systems for harsh environments.
We work with your design team to develop custom anchorage and tendon configurations for non-standard applications.
External post-tensioning allows strengthening without interrupting operation — critical for bridges and industrial facilities.
All products manufactured to GB/T 14370, ISO 9001, and compliant with international post-tensioning standards.
Key Technical Considerations for Strengthening & Special Structures
| Consideration | Recommendation |
|---|---|
| External tendon routing | Use deviation saddles to achieve required force profile — avoid sharp bends to prevent strand damage |
| Corrosion protection | Select grouted or greased-and-sheathed system based on exposure conditions — critical for long-term durability |
| Anchor zone reinforcement | Ensure sufficient reinforcement to handle concentrated anchor forces — use spiral reinforcement and supplementary rebar |
| Monitoring | Install load cells and monitoring systems for long-term force verification and structural health assessment |
| Strand seating | Allow for seating losses in design calculations — typically 3–5mm for external tendons |
