Intelligent asphalt pavement repairing vehicle and construction method

Abstract

The invention provides an intelligent asphalt pavement repairing vehicle and a construction method. The intelligent asphalt pavement repairing vehicle comprises a walking vehicle body, wherein a planing and milling device capable of ascending and descending is arranged on the walking vehicle body; a refrigerant nozzle is arranged in front of the planing and milling device, is connected with a refrigerant storage tank, and is used for spraying a refrigerant to cool the pavement of a pavement sign to be treated; a GPS positioning device and a gyroscope are arranged on the walking vehicle body; and a camera device is at least arranged at the bottom of the walking vehicle body and faces the direction of the pavement. According to the scheme that low-temperature airflow is sprayed out through the refrigerant nozzle to embrittle the pavement sign, planing, milling and removing are facilitated, knife sticking in the construction process is avoided, and the removing efficiency can also be greatly improved through the adopted multi-saw-blade roller structure. By adopting an intelligent control positioning scheme, the equipment control difficulty of an operator can be greatly reduced, and the construction efficiency and safety are improved. The intelligent asphalt pavement repairing vehicle can be used for repairing defects of the asphalt concrete pavement, and can also be used for removing pavement marker lines.

Description

technical field [0001] The invention relates to the field of asphalt concrete pavement construction, in particular to an intelligent asphalt pavement finishing vehicle and a construction method. Background technique [0002] Asphalt concrete pavement is a very widely used road surface. The pavement is usually provided with road marking lines. After a period of use, the pavement marking lines are easy to wear or have modifications. The marking lines often need to be repaired or changed. The trimming of the existing asphalt concrete pavement for municipal engineering is generally carried out manually. At first, the damaged part of the asphalt pavement is chiseled out together with the surrounding parts by the staff using tools such as rakes and chisels, and the chiseled part is cleaned, and then Lay asphalt concrete manually, then use hot pressing device to melt and smooth the asphalt, and finally wait for the asphalt to dry; however, the above steps need to be carried out man...

AI Technical Summary

Problems solved by technology

However, this scheme also has relatively large technical problems. Due to the high viscosity of asphalt in asphalt concrete, it is easy to stick to the knife during the cutting process, which affects the subsequent milling efficiency, especially for the scheme that only cuts a small amount of asphalt concrete. Solution requires frequent downtime to clean tools

There is also a solution to use grinding wheels for grinding, but this solution is less efficient

Existing construction devices or vehicles involving asphalt concrete need to train very skilled technical workers. The existing problem is that due to the particularity of asphalt concrete construction, it is very difficult to train skilled workers who understand the operation of special equipment and are familiar with asphalt concrete construction.
