A repair structure for damaged cracks on municipal pavement

Abstract

The invention relates to a repair structure for damaged cracks on municipal pavement, which belongs to the technical field of road surface engineering equipment. It includes a vehicle frame and walking wheels arranged at the four corners of the bottom of the vehicle frame. One side of the vehicle frame is provided with a push handle. The main technical points are : the frame is provided with a smoothing device, and the smoothing device includes a smoothing part arranged at the bottom of the frame and a driving mechanism for driving the smoothing part to move, and the driving mechanism includes a sliding assembly connected with the smoothing part and a drive The sliding assembly is a driving assembly for reciprocating movement, the sliding assembly is slidingly connected with the vehicle frame, and the sliding direction of the sliding assembly is parallel to the moving direction of the vehicle frame. The invention proposes a structure for repairing damaged cracks on municipal pavements. By installing a smoothing device on the vehicle frame, the user can smooth the concrete filler during the process of pushing the vehicle frame to improve the smoothing efficiency.

Description

technical field [0001] The invention relates to the technical field of pavement engineering equipment, in particular to a damaged crack repair structure for municipal pavement. Background technique [0002] With the construction of modern cities and the rapid development of urban roads, the traffic volume has increased, not only the number of vehicles, but also the load capacity and speed of vehicles. Vehicles, external weather and changes in its own materials and other influences will inevitably cause cracks in the road surface, especially the concrete road surface. [0003] Cracks appear in the road surface, if they are not repaired in time, the long and narrow cracks will further expand, thereby destroying the road. Most of the existing crack treatment methods are to cut and clean up the places that need to be repaired, remove the loose sand and gravel, and then inject the filled concrete filler into the cut cracks; in order to ensure the smoothness of the road, it is ne...

Problems solved by technology

Most of the existing crack treatment methods are to cut and clean the place that needs to be repaired, clean up the loose sand and gravel, and then inject the filled concrete filler into the cut crack; in order to ensure the smoothness of the road surface, it is necessary to The place where the filler is injected is smoothed, so that the filler hardens to form a surface at the same level as the surrounding road surface. However, due to the narrow cracks, the existing smoothing equipment is difficult to use, and manual smoothing is not only labor-intensive. , and low efficiency
