Underground Utility Tunnel

Comprehensive Utility Tunnel Monitoring


Urban comprehensive pipelines, including communication, electricity, water supply, drainage, heating, and gas pipelines, are critical infrastructures for future smart city development. With the extensive development of smart cities, these pipelines span millions of kilometers, serving as the lifelines of cities. Utilizing advanced fiber optic sensing technology and integrating various Internet of Things (IoT) sensor technologies within comprehensive utility tunnels enables comprehensive intelligent sensing of underground utility tunnel operations. This includes real-time monitoring and warning against external damage, temperature monitoring, fire and anomaly alarms. Combined with visualized comprehensive management software and intelligent data processing capabilities, it establishes a new management mode for integrated “monitoring, operation, and command” of underground pipe networks, significantly enhancing urban underground network security and protection capabilities.

 

Subsurface Imaging


Using DAS technology on optical cables within urban infrastructures such as telecommunications and power networks, environmental noise can be collected and analyzed to perform surface wave imaging, achieving shallow subsurface imaging. DAS technology leverages existing optical cables for easy deployment, low maintenance costs, high observation density, and provides high-resolution regional-scale urban geological imaging, demonstrating significant advantages.
