Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a road surface compaction detection device. Background Art

[0002] After the construction of the highway is completed, the highway engineering supervisor needs to test the compaction of the road surface through relevant equipment according to relevant requirements, and the compaction of the road surface also needs to be tested within the specified time. There are many methods for testing the compaction of the road surface, such as the core drilling method, which takes samples from the road surface and calculates the ratio of the dry density of the sample to the standard maximum dry density.

[0003] For example, the utility model patent application with the authorization announcement number CN216621825U and the name of a road surface compaction detection device for highway engineering supervision includes a pair of relatively arranged vertical plates, and the top of the vertical plates is fixedly connected to a support plate with a through hole in the center. The upper end surface of the support plate is provided with a pair of vertically arranged vertical poles, and the top of the vertical poles is fixedly connected to a fixed plate with a through hole in the center. A sleeve is fixedly connected between the through hole of the support plate and the through hole of the fixed plate. A motor is fixedly connected to the fixed plate in a vertical downward direction, and the rotating shaft of the motor is sleeved inside the sleeve. The rotating shaft of the motor is fixedly connected to a lead screw, and the outer sleeve of the lead screw is provided with a threaded barrel for matching use. The outer wall of the threaded barrel is fixedly connected to a horizontally arranged balance bar, and the balance bar can be slidably installed on the vertical plate. A sampling barrel for sampling on the road surface is fixedly provided below the threaded barrel.

[0004] When sampling, the sampling tube of the existing road surface compaction detection device moves linearly under the drive of the motor. When the sampling tube is inserted into the ground and removed, an annular gap is formed on the road surface, and then the staff can take out the sample inside the annular gap through the clamp to test the compaction of the sample. However, since the size of the sampling tube is fixed, the width of the annular gap is the thickness of the side wall of the sampling tube. As a result, it is not easy to extend the clamp into the annular gap to clamp and take out the sample inside the annular gap. Utility Model Content
