Using an infrared thermal imaging camera to monitor rock deformation during tunnel excavation is an important technical method.
Real-time monitoring: An infrared thermal imager cameras can monitor the temperature changes of the surrounding rock in real time during tunnel excavation. Temperature changes are often associated with rock deformation and fracturing. By monitoring these changes, potential dangers can be promptly detected.
Non-contact measurement: The infrared thermal imager camera is a non-contact measurement tool that can avoid direct contact with the rock, reducing interference with tunnel construction. At the same time, it can carry out measurements in hazardous environments, ensuring the safety of operators.
High-precision detection: The infrared thermal imaging camera features high resolution and high precision, capable of capturing subtle temperature changes. This helps identify local stress concentration areas and the expansion of cracks in the surrounding rock, thereby preventing sudden incidents.
Large area coverage: The infrared thermal imagers can cover a large area of the surrounding rock surface, providing comprehensive monitoring data. This is particularly important for long-distance tunnel construction, allowing comprehensive control of the stability of the surrounding rock.
Data analysis and early warning: By analyzing the data collected by the infrared thermal imager, a model relationship between temperature changes and deformation of the surrounding rock can be established. Combined with other monitoring methods, such as geological radar and stress sensors, it is possible to achieve comprehensive assessment and early warning of rock deformation.
Strong environmental adaptability: The infrared thermal imager camera can work normally in various complex environments, including high humidity, high temperature, and dusty conditions, making it very suitable for the complex conditions of tunnel construction.
Monitoring during the initial support stage: During the initial support stage of the tunnel, the infrared thermal imaging camera can monitor the temperature distribution of the surrounding rock, helping to detect whether the initial support is in place and whether there is uneven deformation in the surrounding rock.
Long-term monitoring: After the completion of tunnel construction, the infrared thermal imaging camera can still be used for long-term health monitoring of the surrounding rock, ensuring the long-term stability and safety of the tunnel.
Through these applications, infrared thermal imager cameras have played an important role in the study of rock deformation during tunnel excavation and have provided guarantees for the safety and efficiency of tunnel construction.
