The ways in which tunnel intelligent equipment enhances safety during construction primarily include the following aspects:

Real-time Monitoring and Early Warning: By installing various sensors and monitoring equipment such as deformation monitoring, stress monitoring, groundwater monitoring, environmental monitoring, and crack monitoring, we achieve real-time supervision of the tunnel structure. Once the monitored data reaches the preset alarm threshold, the system will immediately trigger the early warning mechanism, notifying relevant personnel through various means such as sound and light alarms, text messages, and emails, to ensure timely detection and handling of potential safety hazards.

2. Personnel and Vehicle Positioning System: Utilizes UWB (Ultra-Wideband) technology for high-precision positioning of personnel and vehicles within tunnels, providing real-time monitoring of their location information, ensuring safety, and offering precise rescue support in emergencies.

3. Gas Detection: Install gas detection equipment to monitor harmful gas concentrations in tunnels in real-time, such as sulfur dioxide, and immediately trigger an alarm if the concentration exceeds the limit, ensuring necessary measures are taken to protect the health and safety of construction workers.

Emergency Communication System: Established an emergency communication network within the tunnel, including wireless intercom systems, emergency phones, and call buttons, for swift communication and response in case of emergencies.

5. Access Control System: Installed an access control system using technologies such as IC cards and facial recognition to manage the entry and exit of personnel and vehicles within the tunnel, preventing unauthorized access to hazardous areas.

6. Smart Video Surveillance: High-definition cameras provide real-time monitoring inside and outside tunnels, capturing live images of traffic conditions, structural changes, and geological environments, offering a direct basis for early detection of anomalies.

7. Digital Twin Technology: By creating virtual models of tunnels, we achieve real-time monitoring and predictive maintenance of tunnel conditions, enhancing the safety and efficiency of tunnel construction.

8. Holographic Tunnel: Through Lai Shi's precise perception and proactive event reporting, combined with digital twin technology, achieving "pre-event prevention, in-process monitoring, and post-event review" for tunnel traffic safety management.

The application of these intelligent equipment and technologies significantly enhances the safety in tunnel construction, effectively preventing and reducing the risk of accidents.
