A full-coverage pavement repair device

Abstract

The invention relates to the field of road surface repair, in particular to a full-coverage road surface repair device. The object of the present invention is to provide a full-coverage road surface repairing device. The technical solution is: a full-coverage road surface repair device, including the first frame plate, wheels, push handle bar frame, operation control panel and second frame plate, etc.; the upper part of the wheel is connected with the first frame plate by bolts ; The lower part of the push handle bar frame is welded with the first frame plate; the operation control panel is connected with the push handle bar frame. The invention realizes the simultaneous spraying of multiple groups of nozzles, increases the speed of spraying and covering the bottom surface of the pit, and the side nozzles can automatically adjust the height, quickly coats the side walls of pits with different depths, and covers the asphalt filler after the pit is buried. flattening effect.

Description

technical field [0001] The invention relates to the field of road surface repair, in particular to a full-coverage road surface repair device. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] At present, in the process of repairing pits on asphalt pavement in the prior art, the asphalt fragments inside the pits on asphalt pavement are first cleaned and separated, and then it is necessary to spray solidified adhesive on the inner surface of the pit to prevent the bottom layer from The soil is loose, and the asphalt layers of different pavements have different depths. It is difficult to spray evenly on the side ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the prior art in the process of repairing the pits on the asphalt pavement, firstly the fragmented asphalt inside the pits on the asphalt pavement is cleaned and separated, and then it is necessary to spray the solidified adhesive on the inner surface of the pits to prevent the bottom The soil is loose, and the asphalt layers of different pavements have different depths. It is difficult to spray evenly on the side walls and inner bottom surfaces of potholes with different depths. During the spraying process with hand-held spray guns, it is difficult for manpower to control side wall spraying and partially solidified adhesive spraying. To the outside of the pit, it will cause waste of raw materials, and the spraying efficiency is low. At the same time, after the new asphalt filler is manually refilled into the pit, it needs to be re-flattened with a road roller, but some pits with relatively large areas are filled manually. In the process, it is impossible to ensure that the amount of asphalt filler inside the unit area of ​​the entire pit is the same. After the roller is flattened, the amount of asphalt filler inside the unit area is different, that is, there is a shortcoming of unevenness after the roller is flattened. The purpose is to provide a full coverage pavement repair device
