Description

Technical Field

[0001] This utility model relates to the field of tunnel crack detection technology, specifically to a crack detection device for the top and side surfaces of a water conveyance tunnel. Background Technology

[0002] Water conveyance tunnels are underground corridors that facilitate the inter-regional allocation of water resources by traversing mountains or deep strata. They typically employ circular or horseshoe-shaped cross-sections to withstand high water pressure. As crucial water infrastructure, the structural safety of water conveyance tunnels directly impacts the stability and security of water transport. Cracks are a common defect in tunnels; if not detected and addressed promptly, they can lead to serious consequences such as leakage, reduced structural strength, and even collapse.

[0003] When detecting cracks on the top and sides of a water conveyance tunnel, ultrasonic probes are typically attached to the inner wall to emit ultrasonic waves. If a crack exists, the ultrasonic waves will be reflected at the crack interface. The probe receives and records the reflected signal, and the crack depth is calculated by analyzing the signal propagation time and intensity. However, the top and sides require manual handheld inspection, which is quite inconvenient. Utility Model Content
