Efficient pouring machine and repair method for highway cracks

Abstract

The invention relates to an efficient pouring machine and a repair method for highway cracks, and belongs to the technical field of pavement repair. The machine comprises a pouring machine body and anasphalt spray gun matched with the pouring machine body for use, wherein an armrest is arranged at the rear end of the pouring machine body; a mounting rack is arranged at the front end of the pouring machine body, and the lower end of the asphalt spray gun extends to the lower part of the mounting rack; the asphalt spray gun comprises a guide pipe and a gun head, a pressure-turning channel shifting group is arranged at the joint of the guide pipe and the gun head, width of the pressure-turning channel shifting group is reduced gradually from front to back, multiple channels are distributed in the pressure-turning channel shifting group, inside dimensions of the channels on the front side are larger than those of the channels on the rear side, and the lower end surface of the pressure-turning channel shifting group is a convex arc surface; a slide plate capable of sliding oppositely to the convex arc surface is mounted at the upper end of the gun head, and the other end of the gun head extends to the lower part of the mounting rack. On the basis that crack width changes irregularly, the cracks with different widths can be filled in a targeted manner by the machine capable of adapting to crack width change.

Description

technical field

[0001] The invention relates to the technical field of road surface repair, in particular to a high-efficiency crack filling machine for road cracks and a repair method thereof. Background technique

[0002] In the damage of highway bridges, the most common is highway cracks. Highway cracks are cracks in the surface layer or cracks in the surface layer caused by the subsidence of the base. When cracks appear in the road, rainwater and groundwater will enter the foundation layers more smoothly. The vehicle is constantly rolling, and the erosion effect of the water infiltrated into the foundation is superimposed, which greatly aggravates the damage progress of the roadbed, resulting in faster damage to the more damaged road. In areas with dense vehicle traffic, tiny cracks and subsidence will expand rapidly, resulting in obvious damage. Under the influence of repeated rolling by vehicles, the cracks and wave pits in the lower road layer will gradually expand, a...
