The drill pipe 2242 is generally a cylindrical drill pipe 2242, and is made of high-wear-resistance alloy steel, and a diamond grinding head is arranged at the edge of the lower end of the drill pipe 2242.
When the drilling mechanism 22 works, firstly, the drilling machine 2241 drives the drilling cylinder 2242 to rotate, the third driving piece 223 drives the mounting plate 222 to move downwards to drive the drilling cylinder 2242 to drill into the asphalt pavement, after the drilling depth reaches a preset depth, the third driving piece 223 drives the mounting plate 222 to ascend to drive the drilling cylinder 2242 to ascend, and at the moment, the asphalt sample core may be remained in the drilling cylinder 2242 or may remain on the pavement. When the core remains in the barrel 2242, the barrel 2242 may be tapped lightly to drop the core. When the sample core is left on the road surface, the sample core can be clamped and taken out by a clamp or other tool.
Because the drill 2242 rotates to cut the asphalt pavement to obtain the sample core during the core drilling, the drill 2242 and the asphalt pavement generate heat by friction in the process, so that asphalt is easily melted and adhered to the inner wall of the drill 2242, and more dust is generated. To solve this problem, referring to fig. 1, 2, 3, 5 and 6, in some possible embodiments, an annular water retaining boss 2243 is disposed on an upper end surface of the drill cylinder 2242, the water retaining boss 2243 and the upper end surface of the drill cylinder 2242 form a water storage cavity with an upward opening, and a water inlet 2244 is formed at the bottom of the water storage cavity and is communicated with the sampling cavity; the drilling mechanism 22 further includes a water cooling unit 225, and the water cooling unit 225 includes a water storage tank 2251 and a cooling water pump 2252.

The addition of the water cooling unit 225 has the advantages described above, but has drawbacks. The cooling water overflows and flows onto the pavement in the drilling process, and substances such as mud, asphalt particles and the like are mixed in the overflowed cooling water, so that the cooling water is not pure. For newly paved asphalt pavement, overflowed cooling water can seriously affect the attractiveness of the pavement after being air-dried on the pavement, and can also cause difficulties in subsequent pavement marking (such as crosswalk lines, lane lines, parking lines and the like).

In the above embodiment, increasing water cooling can improve the uniformity of the drilled section, reduce dust and reduce abrasion, but residual water in the holes can affect the subsequent repair of the asphalt pavement. Although the surplus water can be pumped away by the sewage pumping unit 226, a small portion of the water is inevitably remained on the inner wall of the hole. When water is reserved on the inner wall of the hole, the bonding strength of the asphalt mixture and the inner wall of the hole can be influenced, and the pavement repair quality can be influenced.

The temperature of the hot air is set according to the softening point temperature of the asphalt mixture, such as 80-200 ℃, and the temperature is set according to the condition that asphalt pavement can be softened. Since the asphalt mixture is a mixture, its softening point is not fixed, and can be obtained by practical tests. The heating tube 39 may be a resistance wire heating type or a fuel combustion type heating type, and heats the air flowing therethrough, and blows the heated air out of the heating port by a centrifugal fan incorporated therein. The hot air blown out can blow the water in the holes to dry on one hand, and on the other hand can heat the asphalt pavement, so that the bonding strength between the asphalt pavement and the repairing material is improved, and the pavement repairing quality is improved.

Because the asphalt needs to be heated during pavement repair, peculiar smell can be radiated when the asphalt is heated, on one hand, the air can be polluted, and on the other hand, the body health of surrounding test sampling personnel can be endangered. At higher road surface repair loads, the volume of the heating cartridge 32 needs to be made larger to accommodate more asphalt mix. In this case, the asphalt mixture in the heating cylinder 32 is always heated, which consumes much energy and also continuously endangers the health of the surrounding test samplers.
In order to solve the above problem, referring to fig. 9 and 10, in some possible embodiments, the heating barrel 32 has a heating channel passing through from top to bottom, a discharge hole 321 is formed at the bottom of the heating channel, the sample repairing assembly 30 further includes a asphalt barrel 40 disposed on the second support 31, the asphalt barrel 40 is disposed above the heating barrel 32, and a discharge valve is disposed at the bottom of the asphalt barrel 40.

In order to ensure that the asphalt mixture has sufficient compactness, the pressure applied by the second lifting end 334 to the weight 331 needs to be large enough. Because the forces are mutually applied, when the lifting unit applies downward pressure to the heavy punch 331, the lifting unit can be subjected to upward force, and the force acts on the second bracket 31 through the lifting unit, so that the deformation of the bracket body structures such as the second bracket 31 can be caused for a long time, the position and the matching precision of each part are affected, and the positioning precision of a subsequent repairing mechanism, a compacting mechanism and the like can be also affected.

Compared with the application of pressure to the heavy punch 331 by adopting the power parts such as the hydraulic rod, the pneumatic pressure rod and the like, the impact force of the heavy punch 331 acting on the asphalt mixture in the embodiment depends on the gravitational potential energy accumulated by the heavy punch 331, the second bracket 31 and other bracket body structures are smaller in stress, deformation is not easy to occur after long-time use, and the position and the matching precision of each part are guaranteed to be accurate.
