Infrastructure Inspection

20250407 Underwater Robot Inspection of Submerged Infrastructure

Underwater robots are applied for regular inspection of submerged infrastructure, providing robust protection for the safe operation of "underwater lifelines" including cross-sea tunnels, submarine pipelines and bridge piers/pile foundations. Equipped with HD imaging equipment, sonar detection systems and non-destructive testing modules, these robots accurately perform structure flaw detection, crack monitoring and attachment inspection tasks in complex hydrological environments, while transmitting high-definition data in real time for evaluation report generation. Compared with traditional manual diving inspections, they overcome limitations of water depth and visibility, improve operation efficiency by over 300%, and eliminate risks to human divers. This application transforms submerged infrastructure inspection from "periodic manual spot checks" to "intelligent regular monitoring", offering a technological solution for infrastructure safety maintenance and driving underwater engineering management toward precision and intelligence.

20250220 Bridge Pier Sonar Inspection

The multi-beam imaging sonar has a rated pressure-resistant water depth of 300m, with multiple operating frequencies available and an effective detection range of ≥ 70m. It supports equal-angle and equal-distance beam modes, and its 512 beams can handle most detection tasks. The target of this sonar test was the opposite bridge pier. The multi-beam sonar covers a wide water area and captures high-resolution underwater images.
