Problems solved by technology

Since the width of the expanded joint is only a few centimeters, it is very inconvenient and time-consuming to fill in the expanded joint, and the filler spilled on both sides of the expanded joint cannot be completely recovered, resulting in an unsightly repair of road cracks

Embodiment 1

[0026] The present invention is an urban road crack repair device after seam expansion. The main structure includes a door-shaped plate 1, a telescopic mechanism and a bottom plate 2; the door-shaped plate 1 and the bottom plate 2 are connected by a telescopic mechanism, and the telescopic movement The distance between the top plate and the bottom plate 2 of the door panel 1 can be adjusted. The side plates on both sides of the door-shaped plate 1 are provided with through holes 3 .

[0027] After filling the device and stuffing the device into the expansion joint, the top of the device is about one centimeter above the ground. During the subsequent compaction process, the telescopic mechanism shrinks, and the packing in the device is compacted to ensure the packing density. The packing in the device will flow from the door The through-holes 3 of the side plates on both sides of the shaped plate 1 overflow to fill the gap between the side plates and the expansion side walls, a...

Embodiment 2

[0033] Compared with Embodiment 1, the telescopic mechanism in Embodiment 2 is a sliding connection mechanism in the vertical direction. Risers 10 are provided on both sides of the bottom plate 2, and a flange 11 is provided on the top of the riser 10. The bottoms of the side plates on both sides of the door-shaped plate 1 are provided with stoppers 12, and after the flange 11 contacts the stoppers 12, the stoppers 12 limit the position of the flange 11. When the telescopic mechanism is in the extended state, the flange 11 contacts the stopper 12, as shown in the accompanying drawings Figure 6 State diagram before compaction. When the telescopic mechanism is in the retracted state, the flange 11 is located above the block 12 and away from the block 12, as shown in the accompanying drawings Figure 6 State diagram after compaction. This kind of telescopic mechanism is more practical, and there is no need to set the second sliding rail 8 on the guard plate 4, and the second s...

Abstract

The invention discloses a road crack repairing device after crack expansion, and mainly relates to the field of urban road crack repairing tools. The device comprises a door-shaped plate, a stretchable mechanism and a bottom plate, wherein the door-shaped plate is connected with the bottom plate through the stretchable mechanism; stretchable movement of the stretchable mechanism can adjust the spacing between a top plate and the bottom plate of the door-shaped plate; and through holes are formed in side plates on both sides of the door-shaped plate. The device further comprises guard plates connected to the side plates on both sides of the door-shaped plate in a detachable manner. The device has the advantages that the device can effectively and aesthetically repair road cracks after crackexpansion and dust removal.

Description

technical field [0001] The invention relates to the field of tools for repairing urban road cracks, in particular to a repairing device for road cracks after expansion. Background technique [0002] As far as the repair of road cracks is concerned, different crack widths use different methods. For small cracks with small cracks and chicken claw cracks, the construction is simple and can be repaired without opening the cracks and pouring the crack repair slurry directly, and the repair speed is fast. For cracks with larger crack widths, the current method is to complete the four steps of crack expansion-dust removal-filling-compaction. After the seam is expanded to a certain width and depth by the hand-push seam cutting machine, the soil residue in the crack is treated with blower and dust removal equipment such as a nozzle-type blower dust remover, and the loose debris remaining in the seam after expansion is completely removed. . Then carry out packing and post-filling c...
