Description

Technical Field

[0001] The utility model relates to a highway sampling and detection device, in particular to a highway compaction rapid sampling and detection device, belonging to the technical field of highway compaction detection. Background Art

[0002] During the roadbed construction process, the control of the compaction degree of the roadbed filler is the key to the quality control of the roadbed construction. The commonly used methods for testing the compaction degree of the roadbed include the ring knife method, the sand filling method, the wax sealing method, the water filling method, the coring method, the nuclear wet density meter method, etc. The sand filling method uses uniformly granular sand to replace the volume of the sampling test hole. Many projects list the sand filling method as the primary method for on-site density determination.

[0003] In Chinese patent application publication number CN221545553U, a device for rapid sampling and detection of highway compaction is disclosed. In this utility model, a drive assembly with a motor is provided to drive a spiral auger to sample the soil of the compacted roadbed. During this sampling process, the soil can be synchronously pushed into a collection tray for collection, avoiding manual soil collection and greatly improving efficiency.

[0004] Although the solution of the above patent can synchronously push the soil into the collection tray for collection, the sampling and detection device in the above patent is not convenient for storing the sampled soil. After the sampling device takes out the soil, the internal soil is easily dropped due to the movement of the device, resulting in insufficient amount of sampled soil for testing. Therefore, a highway compaction rapid sampling and detection device is proposed herein. Utility Model Content
