Description

Technical Field

[0001] The present application relates to the technical field of highway roadbed detection, and in particular to an easy-to-use highway goaf area roadbed thickness detection device. Background Art

[0002] The requirements for expressways are higher than those for ordinary roads, and the supporting strength of roads depends on the structure of the roadbed. Only when the roadbed is fully compacted can the strength, stiffness, stability and flatness of the road surface be guaranteed. The roadbed of expressways is higher than the plane, so it needs to be filled and compacted in layers, and the compaction thickness needs to be detected to ensure the safe use of the highway roadbed.

[0003] Among them, the utility model patent with publication number CN215065343U discloses a highway roadbed detection device, but the above patent still has certain shortcomings when used.

Moreover, the single core sampling cannot achieve accurate detection of the roadbed thickness. For this reason, we provide an easy-to-use highway goaf area roadbed thickness detection device to solve the above problems. Utility Model Content
