[0002] At present, in the process of municipal road pavement construction, asphalt pavement is the main paving method for existing municipal roads due to its advantages of good strength, low shrinkage cracks, and convenient later maintenance. Whether it is a rigid pavement or a flexible pavement, the thickness of its structural layer determines the overall strength of the pavement. Therefore, during the road construction process, the thickness of the pavement structural layer determines the construction quality of the road, and road asphalt paving mainly controls the thickness of the asphalt paving.

[0003] In the past, the main method for detecting asphalt thickness was core sampling detection. For example, the Chinese patent number CN219532559U discloses an asphalt pavement thickness detection device, which uses a pavement core drilling machine to drill holes on the asphalt pavement that has been paved, and then uses a steel ruler to measure the core sample to measure the paving thickness of the asphalt pavement. This method has certain shortcomings: 1. It is a post-test and cannot be controlled during the paving construction process; 2. There is no review function and the accuracy of the test cannot be ensured. Utility Model Content

[0028] See also Figure 1 , is a structural schematic diagram of a preferred embodiment of an asphalt thickness detection device provided by the utility model.

[0029] An asphalt thickness detection device includes a sleeve 6, an electronic distance meter 3 and a detection rod 2:

[0030] The electronic distance meter 3 comprises a body and a sensor. The body of the electronic distance meter 3 is mounted on the sleeve 6. The sensor of the electronic distance meter 3 is arranged on the detection rod 2. The electronic distance meter 3 is used to detect the distance between the sensor and the body.

[0031] The detection rod 2 is inserted into the sleeve 6 and is used to move axially relative to the sleeve 6 and be inserted into the bottom of the asphalt layer;

[0032] The detection rod 2 is provided with a scale 7 , and the scale 7 is used to read the height change value of the detection rod 2 relative to the axial movement of the sleeve 6 and to verify the reading of the electronic distance meter 3 .

[0033] It can be understood that the electronic distance meter 3 is installed through the sleeve 6, and the detection rod 2 is inserted into the sleeve 6 and can be raised and lowered. The sleeve 6 plays a positioning role. The sensor of the electronic distance meter 3 is installed on the detection rod 2. When the bottom end of the detection rod 2 is inserted into the asphalt layer and reaches the bottom, the electronic distance meter 3 can read the change in the height of the detection rod 2, that is, the measurement of the asphalt deposition thickness is completed. The electronic distance meter 3 has an electronic display screen, which is convenient, intuitive and fast to read. At the same time, there is also a ruler 7 on the detection rod 2. The value of the height change of the detection rod 2 read by the ruler 7 can be used to verify the reading of the electronic distance meter 3.

[0034] It should be noted that the real-time detection of the thickness during asphalt paving, i.e., the Songpu thickness, has a practical control significance for the thickness of the asphalt pavement after forming. Asphalt paving generally uses the automatic balance beam of the paver to control the loose paving thickness and flatness. The utility model can perform real-time asphalt thickness detection behind the paver by manual hand-holding.

[0035] Preferably, please refer to Figure 1 and Figure 2 As shown, a first positioning plate 5 is provided at the top of the sleeve 6 , a first positioning hole is opened on the first positioning plate 5 , the first positioning hole is arranged corresponding to the through hole at the top of the sleeve 6 , and the electronic rangefinder 3 is installed on the first positioning plate 5 .

[0036] It can be understood that the first positioning plate 5 and the sleeve 6 are arranged perpendicular to each other. The electronic rangefinder 3 is installed through the first positioning plate 5, which makes it convenient to install the electronic rangefinder 3 in a fixed position and adjust the position of the display screen of the electronic rangefinder 3 to facilitate reading the display screen of the electronic rangefinder 3.

[0037] Preferably, please refer to Figure 1 and Figure 2 As shown, a second positioning plate 8 is provided at the bottom end of the sleeve 6, and a second positioning hole 9 is opened on the second positioning plate 8. The second positioning hole 9 is arranged corresponding to the through hole at the bottom of the sleeve 6, and the second positioning plate 8 is used to abut against the upper surface of the asphalt layer.

[0038] It can be understood that the second positioning plate 8 plays the role of supporting the sleeve 6, and the second positioning plate 8 has a larger contact area with the asphalt surface and has better stability.

[0039] Preferably, please refer to Figure 1 and Figure 2 As shown, the side walls around the second positioning plate 8 are hinged with folding plates.

[0040] It can be understood that when the folding plate is folded to a position horizontal to the second positioning plate 8, the area of ​​the second positioning plate 8 can be increased, thereby increasing the contact area between the second positioning plate 8 and the asphalt surface, providing stronger stability, and the folding plate is also easy to store, facilitating the overall transportation of the detection tool.

[0041] It should be noted that the folding plate can be hinged to the second positioning plate 8 via a torsion spring, so that when the folding plate is folded to a horizontal position, the torsion spring provides a certain downward pressure on the folding plate to maintain the balance of the folding plate. When the folding plate is folded and stored, the folding plate and the second positioning plate 8 can be limited by a hoop, a U-shaped frame, or a bolt.

[0042] Preferably, please refer to Figure 1 As shown, a fastener 4 is provided on the sleeve 6 , and the fastener 4 is used to lock and fix the detection rod 2 relative to the sleeve 6 .

[0043] Specifically, the fastener 4 includes a butterfly bolt, and a screw hole is formed on the side wall of the sleeve 6 . The butterfly bolt is used to pass through the screw hole and tighten the detection rod 2 .

[0044] It is understandable that when the detection rod 2 is inserted into the bottom of the asphalt layer, the detection rod 2 and the sleeve 6 are fastened and limited by the fastener 4 to maintain the stability of the detection rod 2, thereby facilitating the reading of the electronic distance meter 3 and also facilitating the verification of the reading by the ruler 7. Among them, only the butterfly bolt needs to be manually tightened to press the detection rod 2 to achieve the tightening and limiting effect, which is very convenient to operate.

[0045] Preferably, please refer to Figure 1 As shown, the detection rod 2 includes an outer tube and a telescopic inner tube. The telescopic inner tube is used to pass through the outer tube, and the scale 7 is arranged on the outer tube.

[0046] Specifically, a spring buckle is provided on the telescopic inner tube, and a limiting hole is provided on the outer tube. The spring buckle is used to be clamped in the limiting hole when the telescopic inner tube is docked in place relative to the outer tube.

[0047] It is understandable that the detection rod 2 is configured as a retractable structure to facilitate the storage of the detection rod 2 and the transportation of the detection device.

[0048] Preferably, please refer to Figure 1 and Figure 3 As shown, a handle 1 is provided on the top of the telescopic inner tube.

[0049] It is understandable that the handle 1 can be made by welding steel pipes at the construction site, so as to facilitate the hand-held detection rod 2 for detection work.

[0050] Preferably, please refer to Figure 1 and Figure 3 As shown, a drill bit 10 is provided at the bottom of the outer tube.

[0051] It can be understood that the drill bit 10 is set at the bottom end of the detection rod 2. The drill bit 10 is set to a conical structure with a smooth surface or a thread. When the detection rod 2 is rotated by the handle 1, the drill bit 10 can be driven to rotate and insert into the asphalt layer, which is beneficial to improve the smoothness of the detection work of the detection rod 2.
