Asphalt pavement crack filling device

Abstract

The invention relates to the technical field of road construction, in particular to an asphalt pavement crack filling device, which is characterized in that the deflection direction of a wheel is controlled through the relative movement of a probe, so that a spray head always faces the position of a notch; additionally, the nozzle is provided with a flow control device; along with the change of the groove width, the flow change is controlled in real time, and the crack pouring glue is prevented from overflowing or being not filled.

[0002] With the rapid development of my country's social economy, the comprehensive service quality requirements for road traffic are getting higher and higher. However, after a period of use on the road, there will be cracks, potholes, ruts and other diseases on the surface. Among them, cracks are various types of road surface. One of the most common and most likely to occur diseases, the hazards of road cracks not only affect the appearance of the road and driving comfort, but if the cracks are not sealed and repaired in time, it is easier to further expand, making rainwater and other sundries along the road Cracks enter the surface structure and subgrade, causing structural damage to the road, resulting in a decrease in the load-carrying capacity of the road surface, accelerating local or piece-by-piece damage to the road surface, and shortening the service life of the road. Therefore, timely repairs are required after cracks are found;

[0003] For small and medium-sized cracks, the commonly used repair method is the crack filling method, which mainly includes slotting-cleaning-filling, that is, slotting treatment along the direction of the crack, the size of the slot has a certain standard, and then the impurities in the slot are removed. After the material is cleaned up, the joint filling is started. The common method of joint filling is to use the joint filling machine, and the nozzle on the joint filling machine will walk along the opened groove, so as to input the joint filling glue into the crack. However, the traditional joint filling machine When in use, the nozzle cannot always be compared with the notch under manual operation, that is, the nozzle may deviate when moving, so that the joint glue or asphalt leaks out of the groove, which not only wastes raw materials, but also requires subsequent processing , increase the workload, in addition, there is a gap with different widths from the beginning to the end, and the size of the groove will also change. If the nozzle is still moving at the original speed, it will cause the slot width to be filled with glue. Filling and overflowing of the slot where the slot is narrow, not only the repair is incomplete, but the filling effect is reduced, but also follow-up processing is required, which will increase the workload in vain. Therefore, a nozzle that can guide the nozzle and adjust with the slot width The device that controls the flow of the nozzle is more important
