Description

Technical Field

[0001] The present application relates to the technical field of highway goaf areas, and in particular to a highway goaf area roadbed stability detection device. Background Art

[0002] The goaf of a highway is the "goaf" on the highway below the roadbed. It refers to the underground areas that have been mined due to mining of coal, metal mines, etc. Its characteristics are: strong concealment, poor regularity of spatial distribution characteristics, and unpredictable collapse of the roof of the goaf. Therefore, in order to ensure the safety of the highway, it is necessary to test the stability of the highway roadbed.

[0003] At present, during the normal passage of highways, the construction of highways will pass through some mined-out areas. However, after the highway has been in use for a long time, the highway roadbed needs to be inspected. Although the current detection device can detect the roadbed when in use, it is difficult to detect the compressive capacity of the mined-out area under the highway roadbed during the detection process, resulting in inaccurate detection data. For this reason, we propose a highway mined-out area roadbed stability detection device to solve the above problems. Utility Model Content
