Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, and in particular to a device for taking pictures inside core holes of roadbed and pavement. Background Technology

[0002] The roadbed and pavement typically refer to the basic structure of a road, supporting its surface layer, such as asphalt or concrete. The roadbed is a crucial part of road engineering because it directly affects the road's stability, load-bearing capacity, and durability. Core sampling can be used to assess the structural integrity and material properties of the roadbed and pavement during inspection. However, core sampling requires mechanical vibration, which can lead to enlarged cracks in the extracted core samples. Therefore, directly photographing the extracted core samples when establishing a sample library of highway roadbed and pavement internal conditions cannot accurately reflect the actual condition of the roadbed and pavement, thus compromising the reliability of the data in the established sample library.
