Description

Technical Field

[0001] The utility model relates to the technical field of port heavy-load road detection application, in particular to a sensor array frame based on elastic wave detection of port heavy-load roads. Background Art

[0002] The elastic wave detection method is similar to the reflection method used in oil exploration. When the road surface is impacted by an exciter (impact hammer), elastic waves (surface waves, longitudinal waves and transverse waves) are generated. When the elastic waves encounter the interface (the bonding surface of the roadbed layer structure) during the propagation process, they will be reflected. The strength of the reflection reflects the stratification and defect conditions of the roadbed. When the roadbed layer structure has small fluctuations or does not contain weak interlayers, the difference between the media on both sides of the interface is small, forming a weak reflection interface, and the reflected wave is relatively weak. On the contrary, when there is a weak interlayer in the layered roadbed, the medium in the gap is soft soil, which is very different from the reinforced concrete slab and the gravel layer, forming a strong reflection surface, and the elastic wave reflected back is very strong. Therefore, by analyzing the strength of the reflected wave, the distribution of the weak interlayer can be inferred.

[0003] The existing elastic wave detection method requires the use of an array frame in use, and multiple sensors are neatly arranged and installed on the array frame to achieve an evenly spaced fixed-point detection effect. When the traditional array frame is in use, the staff is required to arrange it at equal intervals, which is cumbersome in the arrangement process, thereby reducing the overall work efficiency. In addition, the array frame after arrangement must be tested at multiple points, and the staff is required to perform displacement detection on it. Since the array frame cannot be changed and carried at will, it causes operational difficulties during carrying and displacement. Therefore, the utility model proposes a sensor array frame based on elastic wave detection of heavy-load roads in ports. Utility Model Content
