Description

Technical Field

[0001] The utility model relates to the technical field of roadbed test section construction, in particular to a device for quickly determining compaction effects of different rolling combination modes. Background Art

[0002] Among the existing methods for detecting the compaction of highway subgrades, the most common device for measuring the compaction of subgrades is the sand filling device, which uses a destructive detection method and requires manual digging of test pits. The shape of the test pits, the loose bulk density of the measured sand, and the flatness of the sampling ground surface all affect the accuracy of the sand filling method. Therefore, in the sand filling method, the loose bulk density of the measured sand needs to be measured multiple times, the ground surface needs to be flattened, and the shape of the test pits dug by workers needs to be standardized. When the sand filling method is used to detect the compaction of subgrades on a large scale, the sampling process is separated from the measurement process, and the measurement efficiency is low.

[0003] A roadbed compaction measuring device is proposed in the patent with the publication number CN215925923U, which includes a lifting mechanism, a fourth driving mechanism, a screw, a mobile platform, a blocking member, a lifting platform, a positioning tube, a sampling tube, a second driving mechanism, a transmission assembly, a clamping device, an adjusting member, a clamping plate, a measuring mechanism, a display, and a connecting member. Each clamping assembly can clamp the sample core from multiple directions, thereby ensuring that the entire clamping device 23 stably clamps the sample core. Since the clamping assembly includes a clamping plate 232 and an adjusting member 231, the radial position of the clamping plate 232 in the sampling tube 21 can be adjusted by the adjusting member 231 to adjust the clamping degree of the clamping plate 232 on the sample core, so as to achieve the purpose of clamping the sample core, and the structure is simple and easy to operate. Exemplarily, the clamping plate 232 is connected to the positioning tube 121 of the lifting platform 12 through the adjusting member 231, and the clamping plate 232 partially extends into the first barrel 211 of the sampling barrel 21, so that the clamping plate 232 clamps the core in the first barrel 211. The adjusting member 231 can be a screw arranged along the radial direction of the positioning tube 121 and screwed to the positioning tube 121. The screw is axially locked and circumferentially rotatably connected to the clamping plate 232 to ensure that when the screw is rotated, the clamping plate 232 only moves with the screw, but not with the screw, thereby improving the clamping stability. In order to avoid interference between the clamping plate 232 and the sample core during the process of moving from the second barrel 212 to the first barrel 211, the thickness of the clamping plate 232 can be set to be smaller than the difference between the inner diameter of the first barrel 211 and the inner diameter of the second barrel 212. However, the following problems still exist in this patent:

[0004] The existing device for measuring the compaction effect of the roadbed has a lifting assembly that is too complex, has an angled structure, and is difficult to operate. After sampling, the sample cannot be tested accurately and quickly.

[0005] In view of the above problems, it is necessary to design a device for quickly measuring the compaction effect of different rolling combinations to overcome the above problems. Utility Model Content
