Embodiment Construction

[0033] The following is attached Figure 1-3 The application is described in further detail.

[0034] The embodiment of the present application discloses a method for repairing cracks in highway bridges, referring to figure 1 and figure 2 , including step S1, cutting: cut the roads on both sides of the crack along the length direction of the crack by a road surface cutting machine, and adjust the cutting angle so that the angle between the depth direction of the cutting seam formed during cutting and the good road surface 100 Less than 90°, the included angle is 45° in this embodiment;

[0035] Step S2, trimming; use a shovel to remove the solid between the two cutting seams to form the connecting ditch 200, and keep the side wall and bottom wall of the connecting ditch 200 flat, and the cross section of the connecting ditch 200 along the direction perpendicular to its length is trapezoidal. The arrangement of the connecting ditch 200 facilitates pouring asphalt into it l...

Abstract

The invention relates to a highway bridge crack repairing method, and belongs to the field of highway bridge repairing equipment.The highway bridge crack repairing method comprises the steps that S1, cutting is conducted, specifically, roads on the two sides of a crack are cut in the length direction of the crack; S2, trimming is conducted, specifically, the solid between the two cutting seams is leveled to form a connecting ditch; S3, cleaning is conducted, specifically, the surface of the connecting ditch is cleaned; S4, asphalt is poured, specially, asphalt is poured into the connecting ditch through repairing equipment for pavement repairing. According to the road bridge crack repairing method, the crack is integrally cut off, so that the connecting ditch with the side wall and the bottom wall being flat is formed in the road surface, asphalt flows into the connecting ditch and is fixedly adhered to the side wall and the bottom wall of the connecting ditch, and the repairing effect of the road bridge crack is improved.

Description

technical field [0001] The present application relates to the field of highway bridge repair equipment, in particular to a method for repairing cracks in highway bridges. Background technique [0002] Cracks are often formed on the surface of highway bridges during long-term use. In order to improve the service life of highway bridges, when cracks appear on the surface of highway bridges, workers often need to repair the cracks. Generally, when repairing, the slag and dust inside the cracks are often cleaned first, and then the molten asphalt is poured into the cracks through the joint filling machine to repair the road surface through the asphalt, and finally, the repaired road surface is flattened . [0003] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: due to the irregular shape of the sidewall of the crack, it is difficult for the asphalt to adhere well to the sidewall of the crack under the action of the...
