Sensor system for monitoring gasket displacement in tunnels
The patent US12066103B2 describes a sensor system designed to monitor the geometric properties of gaskets used in tunnels, particularly those that are partially subterranean or immersed. The system includes a sensor that measures the position of various gasket surface portions over time, relative to a reference point associated with tubular structural members of the tunnel. A processor analyzes the data to derive displacement indications for each gasket surface portion and compares these with predefined threshold values. If any displacement exceeds these thresholds, the system generates a warning message, ensuring timely maintenance and safety.
The sensor system can be configured in multiple ways, including the use of optical markers, acoustic transducers, or electromagnetic markers to capture position data. The design allows for the sensor to be positioned within the annular space between the gasket members, facilitating accurate measurements. Additionally, the system incorporates temperature control features to maintain optimal operating conditions for the sensor. The method outlined in the patent emphasizes continuous monitoring and the generation of alerts to prevent potential failures in the gasket sealing, which is critical for maintaining the integrity of the tunnel structure.
