Description

Highway crack processing apparatus that highway engineering was used

Technical Field

The invention relates to the technical field of highway engineering, in particular to a highway crack treatment device for highway engineering.

Background

Highway engineering refers to the work of investigation, measurement, design, construction, maintenance, management and the like of a highway structure. The highway engineering structure comprises: roadbeds, pavements, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, houses, workshops and other service facilities used for construction, maintenance and monitoring, but in long-term use, cracks appear in part of highway sections due to various factors, filling treatment is required for the cracks to ensure the flatness of pavements and the protection of tires of vehicles, the size of the cracks is usually very slim, so that workers usually lift the ground around the cracks completely before filling, fill the cracks again, but the requirement on the purity of materials is very high for filling the pavement, so that the workers also need to clean the dust and the like dug out of the cracks fully before filling, but the manual cleaning is very low in time and labor consumption, which greatly influences the filling treatment rate, the method is unfavorable for the rapid recovery of highways, and furthermore, workers need to spread the filling material when filling the holes at the cracks, so that the filled pavement is tidier and more attractive, but the pavement repairing material is usually cooled faster and has higher viscosity, so that the manual paving can severely slow down the construction period, in the prior art, cleaning before the seam filling and filling of the asphalt liquid after the seam filling are realized by adopting a cleaning brush matched with a subsequent asphalt heating stirring bin and an asphalt liquid nozzle, for example, CN202020316150/CN202011034110/CN201310658618, but the melted asphalt liquid is only injected into the cracks to be repaired by utilizing a simple funnel-shaped or conical-shaped nozzle, so that the quality after the pavement is difficult to control, and the residual asphalt in the paving process can not be maximally utilized and has an attractive effect, we propose a highway crack processing apparatus that highway engineering was used.
