Description

Technical Field

[0001] The utility model relates to the technical field of monitoring, in particular to a novel arc-shaped hoop protection device. Background Art

[0002] Water conservancy projects and national economic development have always been closely linked, and the quality of their construction is directly related to socioeconomic development. Among current water conservancy project construction, diversion tunnel construction is a highly technical and challenging task to control. Due to the uneven spatial distribution of water resources, diversion tunnels are purpose-built to channel water from one region to another, meeting the needs of agricultural irrigation, urban water supply, hydropower generation, and other water resource utilization. However, in real-world environments, the sheer volume of water diverted can impact and damage diversion tunnels. To ensure their safe operation, stress and strain monitoring of typical diversion tunnel sections is necessary.

[0003] Existing monitoring methods for diversion tunnels primarily rely on strain gauges. These can be categorized into embedded and surface-mounted types. For completed diversion tunnels, embedded strain gauges can damage the structural integrity and significantly reduce their resistance to water damage. Therefore, deploying surface-mounted strain gauges within the diversion tunnel can better ensure structural integrity.

[0004] However, due to the large volume of water diverted into the water tunnel, the rapid flow rate, and the corrosive nature of seawater, surface strain gauges cannot be used for direct monitoring within the tunnel, and the backbone optical cables cannot provide long-term, stable data transmission. The complex working environment of the actual water diversion tunnel, with its numerous influencing factors, makes it difficult to ensure accurate monitoring and transmission. A device that can effectively protect sensors for stable monitoring and secure the backbone optical cables from damage is urgently needed. Utility Model Content
