Description
Technical Field
The invention relates to the technical field of pavement crack repair, in particular to a multifunctional pavement crack pouring machine and a crack pouring method.
Background
With the high-speed development of road traffic industry in China, roads of various grades are distributed all over the country. In the long-term use process of the highway, the road surface can be damaged in different degrees, and related departments need to adopt special highway maintenance equipment, such as a multifunctional pavement crack pouring machine and the like to repair the damaged road surface. In general, a multifunctional pavement crack pouring machine for pavement is matched with a blower or a thermal spray gun for use, and the existing multifunctional pavement crack pouring machine usually adopts a liquefied gas heating system to rapidly melt asphalt or crack pouring glue, and the asphalt or crack pouring glue is discharged from a discharge hole under the pressure of an asphalt pump to achieve the effect of crack treatment; the material and the crack wall are tightly combined through pressure injection type crack pouring, and the crack is tracked by using a manually operated universal wheel. The multifunctional pavement crack pouring machine is mainly applied to highway maintenance construction and is used for treating surface cracks of asphalt pavements, cement pavements and sites, vehicles generally run according to lanes on expressways and common roads, cracks are generated most easily at lane boundary positions due to different pavement bearing, and through observation, the cracks generally extend vertically and are different in width and have bifurcated phenomena. In construction, at present, the manual work is operated, and the crack pouring is determined at any position according to the judgment of human eyes, so that workers operate on the road for a long time, the labor intensity is high, the working environment is severe, the working efficiency is low, the risk of traffic accidents is high, moreover, due to the reasons of material loss caused by the stealing work, carelessness in observation and the like, the crack pouring is uneven, the bifurcation crack is forgotten, and the quality of the crack pouring is influenced by human factors.
Secondly, there are two main forms of asphalt pavement crack repair, one is to inject asphalt into the crack under pressure, and the other is to use a crack repair method. The asphalt drip irrigation method can be used for repairing road surface cracks with different widths and different shapes, and the service life of the repaired cracks is longer; however, the operation is complex, and the slotting and the seam expanding are needed for the seam with small width, so that more manpower and material resources are consumed. The crack patching method is a method for directly patching cracks by using a crack sealing material, is simple to operate, and has stronger corrosion-resistant and waterproof effects on common crack sealing materials; but the high temperature resistance and the rolling resistance of the adhesive are weaker, the puncture damage is easy to occur, and the adhesive is not suitable for sealing and adhering wider cracks. It can be seen that the two crack repairing methods have advantages and disadvantages respectively and have complementary performances.
Therefore, the multifunctional pavement crack pouring machine is high in automation degree, capable of automatically positioning and identifying pavement cracks and intelligently selecting different pavement crack repairing methods according to pavement crack conditions, labor-saving, high in working efficiency and capable of greatly reducing construction safety risks of constructors.
