[0034] This embodiment also provides a method for evaluating the construction of a bubble-mixed lightweight soil embankment, using a bubble-mixed lightweight soil embankment construction evaluation device, including the following steps:

[0036] Step 2: Start the cleaning mechanism 2, the cleaning motor 22 drives the two or more rotating shafts 23 to rotate synchronously, thereby driving the cleaning brush 25 to rotate, and remove the impurities on the surface of the embankment;

[0037] Step three, start the detection mechanism 3, use the knocking component 31 to knock the surface of the embankment to detect the strength of the embankment, and then the auxiliary identification component 32 will release magnetic balls to the surface of the embankment. When defects such as depressions and cracks appear on the surface of the embankment, the magnetic balls will gather in the depressions to facilitate identification by the visual identification component 33, and the marking component 34 will mark the defective area to facilitate subsequent processing. After the marking is completed, the magnetic balls will be recycled by the recycling component 35. Specifically, the power motor 311 drives the first rotating shaft 312 to rotate, and the rotation of the first rotating shaft 312 drives the toggle plate 313 to rotate synchronously. The toggle plate 313 will toggle the contact plate 314 upward, and then with the assistance of the first spring 316, the knocking hammer 317 will continue to move up and down to knock on the surface of the embankment, and then the motor 327 drives the first cam 328 to rotate, so that the second baffle 326 reciprocates The magnetic balls in the discharge bin 323 fall into the second through hole 3261, and when the first through hole 3251 and the second through hole 3261 are aligned, the magnetic balls will pass through the first through hole 3251 and fall onto the surface of the embankment, thereby forming a mesh of feature points, which is convenient for the image recognition module 333 to accurately identify the defective area. Then the main control box will control the displacement motor 344 to start, and the displacement motor 344 drives the threaded shaft 345 to rotate. The rotation of the threaded shaft 345 drives the slider 346 to slide, so that the nozzle 347 moves above the defective area. At this time, the pump body 342 starts to spray the powder onto the defective area to complete the marking. Then the magnetic roller 351 will absorb the magnetic balls on the surface of the embankment, and as the magnetic roller 351 rotates, the magnetic balls can fall into the recovery bin 353 along the inclined plate 352 to achieve recycling, reduce testing costs, and prevent environmental pollution.

[0038] Specifically, in step three, the surface of the magnetic ball is coated with a fluorescent layer to facilitate identification and improve the detection success rate of the visual recognition component 33 in conditions of insufficient light such as cloudy days or evenings.

The slider (346) is threadedly connected to the threaded shaft (345). The slider (346) is slidably connected to the vehicle body (1). The slider (346) is provided with a nozzle (347). One end of the corrugated hose (343) is connected to the pump body (342), and the other end of the corrugated hose (343) is connected to the nozzle (347).

7. The device for evaluating the construction of embankment using a bubble-mixed lightweight soil according to claim 1, characterized in that: The recovery component (35) comprises a magnetic roller (351), an inclined plate (352) and a recovery bin (353); the magnetic roller (351) is rotatably connected to the vehicle body (1); a inclined plate (352) is obliquely provided on one side of the magnetic roller (351); a higher end of the inclined plate (352) abuts against a side surface of the magnetic roller (351); a lower end of the inclined plate (352) is connected to the recovery bin (353); and the recovery bin (353) is fixedly provided on the vehicle body (1).

8. A method for evaluating the construction of a bubble-mixed lightweight soil embankment, characterized in that: The device for evaluating the construction of an embankment made of air bubble mixed lightweight soil as described in any one of claims 1 to 7 comprises the following steps: Step 1: Move the vehicle body (1) onto the embankment, and start the vehicle body (1) to move it forward slowly; Step 2: activating the cleaning mechanism (2) to remove impurities on the surface of the embankment; Step 3: Start the detection mechanism (3) and use the knocking component (31) to knock on the surface of the embankment to detect the strength of the embankment. Then, the auxiliary identification component (32) releases magnetic balls to the surface of the embankment. When depressions and cracks appear on the surface of the embankment, the magnetic balls will gather in the depressions to facilitate identification by the visual identification component (33). The marking component (34) will mark the defective area to facilitate subsequent processing. After marking, the recovery component (35) will recover the magnetic balls.

9. The method for evaluating the construction of a bubbling mixed lightweight soil embankment according to claim 8, characterized in that: In step three, the surface of the magnetic ball is coated with a fluorescent layer for easy identification.
