The working principle is as follows: when the utility model is used, as shown in fig. 1, firstly the device is pushed to the asphalt pavement with the required thickness to be detected through the pushing handle 6, then the output retraction of the hydraulic cylinder 3 is controlled through the hydraulic station 34, thus, because the support plate 8 is not pushed by the output end of the hydraulic cylinder 3, the cylinder 12 can move downwards under the drive of the two guide cylinders 7, when the cylinder 12 moves, the first cylinder 17 can also move downwards synchronously along with the cylinder 12 until the inclined plane pipe orifice at the bottom end of the first cylinder 17 passes through the through groove 5 to be contacted with the asphalt pavement, when the inclined plane pipe orifice at the bottom end of the first cylinder 17 is contacted with the asphalt pavement, because of the arrangement of the T-shaped sliding groove 18, the cylinder 12 can continue to move downwards for a certain distance under the action of self gravity until the top end of the first cylinder 17 extends into the sleeve 16 and is attached to the bottom end of the cylinder 12, when the top end of the first cylinder 17 is attached to the bottom, the pneumatic percussion hammer 10 can be started by the air pump 33, so that the output end of the pneumatic percussion hammer 10 strikes the top surface of the fixed plate 13, when the fixed plate 13 is struck, the striking force is transmitted to the first cylinder 17 through the cylinder 12, so that the inclined plane nozzle at the lower end of the first cylinder 17 is embedded into the asphalt pavement, when the bottom end of the first cylinder 17 is embedded into the asphalt pavement, the asphalt pavement in the first cylinder 17 pushes against one end of the V-shaped rod 29 extending into the first cylinder 17, because the natural state of one end of the V-shaped rod 29 extending into the first cylinder 17 is inclined upwards, and the V-shaped rod 29 is hinged in the through hole 27 through the pin 28, when the asphalt pavement pushes against one end of the V-shaped rod 29 in the first cylinder 17, one end of the V-shaped rod 29 in the first cylinder 17 is swung into the through hole 27, and the other end of the V-shaped rod 29 stretches the tension spring 31, so that one end of the V-shaped rod 29 extending into the first cylinder 17 does not affect the embedding of the asphalt pavement, thus, after the inclined plane pipe orifice at the lower end of the first cylinder 17 is embedded into the asphalt pavement to a certain depth (greater than the required measurement standard thickness of 5CM), as shown in fig. 3, the air pump 33 is firstly closed to stop the operation of the pneumatic impact hammer 10, then the hydraulic station 34 controls the extension of the output end of the hydraulic cylinder 3, so that the output end of the hydraulic cylinder 3 jacks the bottom end of the supporting plate 8 again and ascends together, so that the supporting plate 8 can drive the cylinder 12 to ascend together through the guide cylinder 7 and the connecting rod 11 when ascending, the U-shaped connecting rods 21 at the two sides of the cylinder 12 drive the two T-shaped sliders 19 to slide upwards, as the cylinder 12 ascends, the top end of the T-shaped slider 19 can be attached to the inner top end of the T-shaped chute 18, and as the top end of the T-shaped slider 19 is attached to the inner top end of the T-shaped chute 18, the U-shaped connecting rod 21 can pull the first cylinder 17 to ascend together, and as the first, and the other end of the V-shaped rod 29 is pulled by the tension spring 31, so as to move upward along with the first cylinder 17, the tip of the inclined plane at one end of the V-shaped rod 29 tilts upward under the action of the tension spring 31 to abut against the asphalt pavement detection sample in the first cylinder 17, and then a plurality of V-shaped rods 29 can clamp the asphalt pavement detection sample in the first cylinder 17 along with the rising of the first cylinder 17, so as to effectively pull out the asphalt pavement detection sample, thus when the bottom end of the first cylinder 17 rises to the upper end of the base 1, the operation of the hydraulic cylinder 3 is stopped, because the U-shaped connecting rod 21 is rotatably connected with the T-shaped sliding block 19 through the first rotating block 20, 17180 degrees of the first cylinder can be manually rotated, so that the pipe orifice of the inclined plane of the first cylinder 17 faces upward, and the threaded rod 23 is rotated through the handle 24, so that the inner arc surface of the arc-shaped plate 22 is attached to the outer side of the first cylinder 17, thereby, in the process, if the asphalt pavement measuring sample in the first cylinder 17 cannot fall freely, the output end of the first hydraulic cylinder 14 can be started to extend, so that the output end of the first hydraulic cylinder 14 can push the asphalt pavement measuring sample in the first cylinder 17 through the sliding block 15, the asphalt pavement measuring sample in the first cylinder 17 is further enabled to come out of the first cylinder 17, then the effective thickness (the thickness of a natural soil layer is removed) of the asphalt pavement measuring sample is measured through a measuring tool, and the purpose of measuring the thickness of the asphalt pavement can be achieved.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
