[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, waterproof and durable. During the asphalt pavement paving construction, the loose pavement thickness is detected using a homemade steel chisel, and the loose pavement thickness is measured by measuring the insertion depth of the steel chisel with a steel ruler.

Affected by the asphalt pavement construction space, if different areas of the asphalt pavement are inspected, confusion and difficulty in recording may occur, affecting the inspection effect.

[0020] In this embodiment: when using the steel drill rod body 1 for detection, it can be held on the lifting rope 21 to limit the position of the support positioning disk 2. When facing the detection position, the lifting rope 21 can be lowered to make the support positioning disk 2 fit the ground, and the steel drill rod body 1 is positioned and stabilized for detection. The line indicator needle 22 is facing the steel drill rod body 1, which can facilitate reading. The support positioning disk 2 has a fixed thickness. After reading, the thickness of the support positioning disk 2 can be subtracted to obtain the loose thickness. After the detection is completed, the storage tube 3 is provided with a storage cavity 31, and a plurality of identification discs 32 are slidably connected in the storage cavity 31. The rotating rod 41 can be rotated to make the blocking limit drop disc 42 leave the discharge hole 2. 3, at this time, the marking disc 32 located in the storage tube 3 can fall to the ground position, which can not only stabilize the detection work, but also facilitate identification when detecting different area positions, facilitate recording and distinction, and improve the detection effect. When the blocking and limiting falling disc 42 rotates into the active cavity 24, under the action of the torsion spring 45, if no force is applied to the rotating rod 41, the blocking and limiting falling disc 42 is reset and continues to block the bottom position of the storage tube 3. An obvious color or pattern can be set for the outer side of the marking disc 32, so that the position where the marking disc 32 is located is the detection position. When collecting it later, a magnet can be set on the marking disc 32 to improve the collection efficiency.

[0021] The outer wall of the pulling rope 21 is opposite to the handle part of the steel drill rod body 1, and the top of the supporting positioning plate 2 is fixedly connected with an alignment indicator needle 22 corresponding to the steel drill rod body 1; the alignment indicator needle 22 faces the steel drill rod body 1, which can facilitate reading, and the supporting positioning plate 2 has a fixed thickness. After reading, the thickness of the supporting positioning plate 2 can be subtracted to obtain the loose laying thickness.

[0022] The discharge hole 23 is connected to the storage cavity 31, and the thickness of the identification disc 32 is equal to the thickness of the supporting positioning disc 2; the identification disc 32 in the storage tube 3 can fall to the ground position, which can be convenient for identification, recording and distinction when detecting different area positions, thereby improving the detection effect.

[0023] A connecting side plate 43 is fixedly connected to the outer side of the blocking and limiting falling disk 42, and a connecting shaft 44 is fixedly connected to the connecting side plate 43. The outer wall of the connecting shaft 44 is sleeved with a torsion spring 45 for resetting the blocking and limiting falling disk 42; when, under the action of the torsion spring 45, if no force is applied to the rotating rod 41, the blocking and limiting falling disk 42 is reset and continues to block the bottom position of the storage tube 3.

[0024] The top of the connecting shaft 44 is fixedly connected with a rotating rod 41 , and the top of the rotating rod 41 penetrates the supporting positioning plate 2 ; one end of the rotating rod 41 is located outside the supporting positioning plate 2 , so that the blocking and limiting falling plate 42 can be operated conveniently through the rotating rod 41 .

[0025] The support positioning plate 2 is provided with an active cavity 24, and the blocking and limiting falling plate 42 is located in the active cavity 24; the blocking and limiting falling plate 42 rotates into the active cavity 24, which can provide space for the blocking and limiting falling plate 42 to move, and leave the lower position of the storage tube 3, so as to facilitate the release of the identification disc 32.

[0026] The working principle and use process of the utility model are as follows: when using the steel drill rod body 1 for detection, the pull rope 21 can be held in hand to limit the position of the support positioning disk 2. When facing the detection position, the pull rope 21 can be lowered to make the support positioning disk 2 fit the ground, and the steel drill rod body 1 is positioned stably for detection. The line indicator needle 22 faces the steel drill rod body 1, which can facilitate reading. The support positioning disk 2 has a fixed thickness. After reading, the thickness of the support positioning disk 2 can be subtracted to obtain the loose thickness. After the detection is completed, the rotating rod 41 can be rotated to make the blocking limit disk 42 leave the discharge hole 23, and at this time it is located in the storage tube 3. The marking disc 32 can fall into the ground position, which can not only stabilize the detection work, but also facilitate identification when detecting different areas, facilitate recording and distinction, and improve the detection effect. When the blocking and limiting falling disc 42 rotates into the movable cavity 24, under the action of the torsion spring 45, if no force is applied to the rotating rod 41, the blocking and limiting falling disc 42 will reset and continue to block the bottom position of the storage tube 3. A clear color or pattern can be set on the outside of the marking disc 32 so that the position where the marking disc 32 is located is the detection position. When collecting it later, a magnet can be set on the marking disc 32 to improve the collection efficiency.
