[0002] Highway engineering inspection refers to the process of systematically assessing the quality and monitoring the safety of highway engineering projects during the design, construction, and operation stages through professional technical means. It covers a comprehensive review of material performance, structural strength, construction techniques, and functional requirements, aiming to ensure that the project meets design standards and safety requirements.

[0003] When inspecting asphalt roads, random sampling of the finished asphalt road surface is necessary to ensure the safety of the asphalt road project to a certain extent. In order to preserve the integrity of the asphalt pavement as much as possible, specialized equipment is needed to collect samples of the asphalt pavement. For example, an asphalt pavement sampling and testing device with publication number CN211312118U can collect samples while preserving the pavement integrity as much as possible. However, the collected samples are already broken and the pavement layers cannot be distinguished, which is very detrimental to road inspection. Utility Model Content

[0018] As a preferred embodiment, the motion structure further includes: two motion slide rods 4, four return springs 5, and a motion frame 6; the two motion slide rods 4 are respectively installed on the upper wall of the support base plate 1, the motion frame 6 is movably installed outside the two motion slide rods 4, the four return springs 5 ​​are respectively installed between the support base plate 1 and the motion frame 6, the motion frame 6 has mounting holes, and the drive end of the sampling motor 2 is installed in the mounting holes of the motion frame 6 through bearings.

[0019] As a preferred embodiment, the handle structure further comprises two handle extension rods 7 and a grip handle 8; the two handle extension rods 7 are respectively installed on the upper wall of the motion frame 6, and the grip handle 8 is installed between the two handle extension rods 7.

[0020] As a preferred embodiment, the container structure further includes: a container base 9, a container cavity 10, and a container cover 11; the container base 9 is installed on the side wall of the support base plate 1, the container cavity 10 is installed on the upper wall of the container base 9, and the container cover 11 is installed on the upper wall of the container cavity 10 by means of threads, and a retrieval window 14 is provided on the side wall of the container cavity 10.

[0021] Working principle:

[0022] I. Preparations before use: The operator first removes the container cover 11 using the screw thread and places the cylindrical material for backfilling inside the container cavity 10. The cylindrical material used for backfilling should ideally be the same raw material as the collected sample. Next, the operator connects the external AC power supply to this invention to provide energy for the sampling motor 2.

[0023] II. Sampling: The operator moves the device to the asphalt pavement to be sampled by holding the handle 8. The operator positions several positioning pins 13 on the asphalt pavement to fix the device. The device is then activated. At this time, the sampling motor 2 drives the sampling blade 3 to rotate. The operator holds the handle 8 and presses down. The rotating sampling blade 3 drives the saw teeth on its lower wall to rotate, cutting the asphalt pavement. As cutting continues, the operator's hand holding the handle 8 presses down further, allowing the saw teeth to continue cutting the asphalt pavement until the entire asphalt pavement is cut through, allowing a complete asphalt road sample to be collected. During this process, the motion frame 6 moves downward outside the two motion slides 4, compressing the four return springs 5. When sampling is complete, the operator releases the downward pressure from their hand, and the sampling motor 2 resets under the action of the four return springs 5. The operator removes the container cover 11 and then retrieves the backfill material through the retrieval window 14 of the container cavity 10. Specifically, the sampling plate is passed through the retrieval window 14 and placed at the bottom of the receiving cavity. When cylindrical material is placed inside the receiving cavity, it rests on the sampling plate. To retrieve the cylindrical material, the container cover is opened, and the sampling plate is moved upwards to remove the cylindrical material and place it into the empty space left by the sampling. Some concrete is then filled to fill the sampling location. The sample is then placed inside the container cavity 10, and the container cover 11 and container cavity 10 are connected by threads.

[0024] III. Subsequent data storage: Operators need to record the sampling depth by referring to the scale 12 based on the marks left on the outside of the sampling tool 3 during sampling. This data will be used in conjunction with sample analysis.
