Vicam Pipeline Imaging Inspection Empowers Trenchless Short-Pipe Replacement: Technical Advantages and Application Comparison in Pre-Construction Survey

Methodology

1. Pipe camera Inspection

   - Deployed a high-resolution pipeline inspection camera system capable or 360° pan-tilt imaging  

   - Conducted a full-length inspection of the target pipeline (D300mm), documenting structural defects, sediment accumulation, and deformation.  

2. Collapse Localization  

   - Identified exact collapse positions (e.g., at 12.7m and 34.2m from the access point) with ±0.5m accuracy using integrated odometry and 512hz transmitter.  

   - Measured collapse lengths (3.2m and 5.8m respectively) through video analysis and scaling tools.  

Vicam pipe video camera VS Traditional Inspection Methods

Key Findings

- The Flexible Push-Rod Borescope footage revealed:  

  ▶ Partial collapses causing 30-50% cross-sectional blockages  

  ▶ Upstream sediment deposition due to flow disruption  

  ▶ No secondary damage detected in adjacent pipe segments  

Engineering Optimization  

The endoscopic data enabled:  

✓ Preselection of pipe bursting equipment (static bursting head vs. pneumatic tools)  

✓ Calculation of required HDPE replacement pipe length  

✓ Avoidance of unexpected ground penetration risks during trenchless operations  

Conclusion

This case demonstrates how pre-construction endoscopic inspection ensures fail-safe trenchless rehabilitation. By accurately diagnosing pipeline conditions, our technology eliminates guesswork, reduces project risks by an estimated 40%, and guarantees the success of short-pipe replacement projects.
