[0001] The utility model relates to the field of road surface repair equipment, in particular to a device for improving the quality of road surface core drilling and pit repairing. Background Art

[0002] At present, the most common method for road core drilling and pothole filling is hand hammer filling, which has large random variations, large differences in pothole filling quality, and high and low surfaces. There are safety risks during use and quality hazards to the road surface, affecting the use effect and lifespan of the highway.

[0003] On September 22, 2024, with "pot filling and pavement and repair and pole" as the abstract keywords, and checking the option to allow synonym expansion, a search was conducted in the Chinese Patent Publication Database, and the following were found: CN213681627U-A new all-in-one machine for filling potholes and repairing pavement diseases; CN112376376A-A asphalt pavement repair device for highway maintenance and its use method; CN211368320U-Road repair device; CN114657857A-A steel plate truck for repairing potholes in asphalt pavement and its use method; CN202492789U-A bamboo hat-type microwave heating repair machine cover for asphalt pavement; CN211547244U-An asphalt paving device for convenient road repair; CN111778829A-A method for asphalt highway construction; CN115679782A-A method and equipment for repairing potholes with prefabricated blocks in asphalt pavement.

[0028] Embodiment 1: Combining all the drawings; A device for improving the quality of core drilling and pothole filling on the road surface, characterized in that

[0029] The device is provided with a base 1. A vertical guide rod 3 protrudes upward from the middle of the base 1. An overall moving structure 4 capable of moving up and down along the vertical guide rod 3 is arranged on the vertical guide rod 3; There is a hole in the middle of the overall moving structure 4 for passing through the vertical guide rod 3;

[0030] An impact surface is arranged below the base 1;

[0031] One or more moving rods 6 are arranged on the side of the overall moving structure 4. The substantial technical effects and their implementation processes of the technical solution here are as follows:

[0032] On the basis of the original hand hammer pothole filling, a new simple tool is reformed to improve the pothole filling quality and make it more standardized and normalized.

[0033] 1. Specific structure: Abandon the use of hand hammer pothole filling tools and process and improve the light dynamic penetrometer. It mainly consists of a 10KG hammer, that is, the overall moving structure 4, a 103cm long core rod, that is, the vertical guide rod 3, a 10cm diameter and 2cm thick iron support welded at the bottom, that is, the base 1. The drop height of the overall moving structure 4 is 60cm, and the handle grip, that is, the length of the moving rod 6 is 10cm, etc. The structure is simple and the operation is convenient. From point to surface and from bottom to top, it effectively controls the overall quality of road surface pothole filling.

[0034] Beneficial effects: improve the quality of pothole repair, reduce late-stage quality diseases, and make up for the quality defects in damage detection; reduce physical injuries and lower safety risks; improve detection efficiency, making it more professional and standardized.

[0035] For the middle and lower layers, fill them with the same type of structural layer. For potholes with a depth of 18 cm in the upper layer, fill them in three layers. Each layer of filler is backfilled with the same type of hot mixture in the upper layer. Two people cooperate in the operation. Let the overall moving structure 4 fall freely, evenly receive force, and the number of hammer blows should be 15 times. Fill the surface 1 cm with fine materials to fill the gaps, and gently tamp the surface with the overall moving structure 4 to make it flat and dense, so as to achieve the same quality effect as on-site paving.

[0036] Embodiment 2: As a further improvable solution, a parallel solution, or an alternative independent solution, a lower hammer head 2 is arranged below the overall moving structure 4. The substantial technical effects achieved by the technical solution here and its implementation process are as follows: The lower hammer head 2 is made of impact-resistant material, so the impact effect is better.

The substantial technical effects achieved by the technical solution here and its implementation process are as follows: In addition to the hand-held lifting structure in Embodiment 1, this embodiment can adopt a foot-operated method without bending down for repair.

[0038] Embodiment 4: As a further improvable solution, a parallel solution, or an alternative independent solution, the foot-operated structure 10 is a frame structure that can be pulled downward by stepping on it. The substantial technical effects achieved by the technical solution here and its implementation process are as follows: It is convenient for stepping on.

[0039] Embodiment 5: As a further improvable solution, a parallel solution, or an alternative independent solution, there are two moving rods 6.

The substantial technical effects achieved by the technical solution here and its implementation process are as follows: Therefore, the rising height of the overall lifting can be limited above.

[0041] Innovatively, the above effects exist independently, and the combination of the above results can also be achieved with a set of structures.

[0042] It should be noted that the multiple solutions provided by this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects simultaneously.
