Description

TECHNICAL FIELD

[0001] The utility model relates to the field of road surface repair, in particular to a road inspection well peripheral road surface repair structure. BACKGROUND

[0002] At present, along with the continuous growth of our country economy, the urban infrastructure has the remarkable improvement. Especially the city road is more and more wide, and the construction is more and more beautiful, greatly improves people's travel condition. Now the road built by asphalt or concrete and other materials is prone to have cracks after long time use, and the road surface is uneven and other bad conditions, so the road surface needs to be repaired. When repairing or repaving the road surface, in order to ensure that the inspection well is consistent with the height of the new road surface, the structure near the inspection well often needs to be broken, the surface height of the inspection well is improved, and then asphalt or concrete is poured to make the whole road surface on the same horizontal plane. However, in the actual construction site, after pouring asphalt or concrete, the asphalt or concrete above the well cover is removed in order to reposition the well cover, which wastes a lot of construction time.

[0003] The Chinese patent with publication number CN213447919U discloses a road inspection well peripheral road surface repair structure, which comprises a well seat, a first fixed layer arranged on the periphery of the well seat, and a second fixed layer arranged on the upper side of the first fixed layer and the well seat. The upper end surface of the first fixed layer is provided with a containing groove for placing a well cover in the vertical direction. A separation frame is arranged in the containing groove to isolate the second fixed layer.

[0004] The road inspection well peripheral road surface repair structure disclosed in the above patent can realize convenient grouting and laying of the second fixed layer around the well seat under the action of the separation frame and the shielding plate, thereby avoiding the time-consuming process of removing the asphalt and concrete on the well seat after repairing the road surface structure around the well seat. However, on the one hand, the centering assembly in the road inspection well peripheral road surface repair structure of the above structure is fixedly installed inside the separation frame, which requires workers to operate by inserting their hands into the separation frame when adjusting the centering assembly. At this time, the shielding plate is open, which poses a safety hazard of workers falling into the well seat. On the other hand, the outer wall of the separation frame is in full contact with the second fixed layer before being pulled out, which easily leads to a large contact area between the separation frame and the second fixed layer, thereby causing a large consumption of manpower when pulling out and disassembling the separation frame later, increasing the labor intensity of workers.
