Embodiment

[0041] Such as figure 1 As shown, it is a schematic diagram of the damaged area 15 and the repaired area 16 of the asphalt pavement. The area of ​​the repaired area 16 is larger than the area of ​​the damaged area 15. The outline of the repaired area 16 should be parallel or perpendicular to the centerline of the road surface and set at the damaged area 15 10-15 cm outside, the shape should be a rectangle in the direction of the road

[0042] combine figure 2 and image 3 , a construction tool for patching highway asphalt pavement, comprising a drilling machine 1 and a support 2. The support 2 includes a first cross bar 21, a second cross bar 22 and three vertical bars 23, two vertical bars 23 are respectively welded to the lower surface of the first cross bar 21, and a vertical bar 23 is welded to the bottom surface of the second cross bar 22. lower surface. The lower end of each vertical bar 23 is rotatably connected with a universal wheel 14 with self-locking function....

Abstract

The invention relates to a construction tool for repairing a highway asphalt pavement. The tool comprises a drilling machine and a support, the support comprises a first transverse rod, a second transverse rod and a plurality of vertical rods. The first transverse rod is vertically connected with the second transverse rod; the vertical rods are respectively vertical to the first transverse rod andthe second transverse rod; first sliding grooves are formed in the first transverse rod in the length direction and the second transverse rod in the length direction. The first sliding groove of thefirst transverse rod is communicated with the first sliding groove of the second transverse rod; the first sliding groove is slidably connected with a sleeve used for sleeving a drilling machine through a first sliding block, the first sliding block penetrates out of the first sliding groove and is provided with a second sliding groove in the direction parallel to the vertical rod, and a second sliding block is slidably connected in the second sliding groove and penetrates out of the second sliding groove to be connected with the sleeve. The method has the effect of conveniently determining the range and depth of the milling groove.

Description

technical field [0001] The invention relates to the technical field of road surface repair, in particular to a construction tool and a method for road asphalt pavement repair. Background technique [0002] At present, with the construction and development of highway pavement, asphalt pavement has become a common road paving method. At the same time, cracks, damage, and subsidence of asphalt pavement have become the phenomenon of asphalt pavement maintenance. If the asphalt is damaged and is not filled and repaired in time, impurities are easy to enter along the cracks Structural layers, accelerating pavement damage. [0003] In the prior art, the Chinese patent whose publication number is CN109403192A discloses a method for repairing potholes on asphalt pavement, including the following steps: 1. Delineate the scope of the disease according to the disease situation, and use a cutting machine to repair the outline of the pothole along the demarcation 2. Determine the depth o...
