Among them, it is necessary to test the compaction of the roadbed, that is, to test the compaction degree / compactness of the roadbed, so as to ensure the strength, stiffness, stability and flatness of the roadbed and pavement, thereby extending the service life of the roadbed and pavement.

[0003] After searching, a Chinese patent discloses a roadbed compaction detection device (authorization announcement number CN209606126U), including a base plate, the left and right sides of the top of the base plate are fixedly connected with brackets, the end of the bracket away from the base plate is fixedly connected with a support plate, the front of the support plate is fixedly connected with a fixed box, the right side of the top of the support plate is fixedly connected with a first support, the right side surface of the fixed box is fixedly connected with a second support, the front of the first support is fixedly connected with a sleeve, and the end of the sleeve away from the first support is sleeved with a rotating shaft. Although this patented technology can drive the turntable to rotate together by rotating the handle, since the turntable is fixedly connected to the rotating shaft, and under the action of the sleeve and the bearing, the rotation of the turntable drives the rotating shaft to rotate together, and since the gear is fixedly sleeved on the surface of the rotating shaft, the rotation of the rotating shaft drives the gear to rotate together, thereby providing power for the drill bit to descend.
