Description

Road crack repairing device after crack expansion

Technical Field

The invention relates to the field of urban road crack repairing tools, in particular to a road crack repairing device after crack expansion.

Background

In the case of road crack repair, different methods are used for different widths. For small cracks with small seam width and chicken feet cracks, the construction is simple, the cracks are not required to be opened, and the cracks can be directly filled with crack repairing slurry for repairing, so that the repairing speed is high. For the cracks with larger seam width, the current method is completed by four steps of seam expansion, dust removal, filling and compaction. After the seam is expanded to a certain width and depth by the hand-push type joint cutter, the soil slag in the seam is treated by using blowing dust removing equipment such as a nozzle type blowing dust remover, and loose slag remained in the seam after the seam is expanded is completely removed. Then the filling and the post-filling compaction are carried out. In order to ensure the construction quality, the filler needs to be higher than the road surface by about one centimeter, and the density of the filler in the crack can be ensured in the subsequent compaction process. Because the width of the expansion joint is only a few centimeters, the whole process of filling the filler into the expansion joint is inconvenient and time-consuming, and the filler scattered on the two sides of the expansion joint can not be completely recovered, so that the road crack is not attractive after being repaired.

Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

For the cracks with larger seam widths, the current method is completed by four steps of seam expanding, dedusting, filling and compacting. Because the width of the expansion joint is only a few centimeters, the whole process of filling the filler into the expansion joint is inconvenient and time-consuming, and the filler scattered on the two sides of the expansion joint can not be completely recovered, so that the road crack is not attractive after being repaired. The above-mentioned problems can be solved well by the design of the road crack repairing device, and the following structural and functional descriptions are provided for two embodiments of the device.

Example 1:

the invention relates to a device for repairing a crack of an urban road after crack expansion, which comprises a main body structure, a gate plate 1, a telescopic mechanism and a bottom plate 2; the door-shaped plate 1 is connected with the bottom plate 2 through a telescopic mechanism, and the distance between the top plate of the door-shaped plate 1 and the bottom plate 2 can be adjusted through telescopic movement after the telescopic mechanism is retracted. And through holes 3 are formed in the side plates on the two sides of the door-shaped plate 1.

After the device is filled into the crack expanding device, the top of the device is higher than the ground by about one centimeter, the telescopic mechanism shrinks in the subsequent compaction process, the density of the filler is ensured by compaction of the filler in the device, the filler in the device can overflow from the through holes 3 of the side plates on two sides of the door-shaped plate 1 to fill the gap between the side plates and the crack expanding side wall, and the top surface of the device after compaction is flush with the ground. The repairing mode completely abandons the existing repairing mode, is a revolutionary invention creation, greatly shortens the time of the filler in the expansion joint, prevents the filler from scattering on two sides of the expansion joint, and can efficiently and beautifully repair the road crack after expansion joint dust removal.

When the packing box is used, firstly, the packing is filled in a cavity formed by enclosing the door-shaped plate 1, the telescopic mechanism and the bottom plate 2, the through holes 3 of the side plates on two sides of the door-shaped plate 1 need to be plugged in the process, otherwise, the packing can be spilled out from the through holes 3. For better sealing of the through hole 3, protective plates 4 are detachably arranged on the side plates on the two sides of the door-shaped plate 1. Backplate 4 uses when filling in to the cavity, just need take off backplate 4 of both sides when needing to place this device after filling in the dilatation joint, because just so can embody through-hole 3's effect in the compaction process, thereby the packing in the device can spill over from through-hole 3 and fill the gap between curb plate and the dilatation joint lateral wall.

In order to realize the detachable connection between the guard plate 4 and the side plates more economically and conveniently, a first sliding rail 5 is arranged on the guard plate 4, first sliding grooves 6 which are in sliding connection with the first sliding rail 5 are arranged on the side plates on two sides of the door-shaped plate 1, and the detachable connection is realized through the sliding connection mode. The detachable connection can of course also be realized in a conventional manner by means of snapping or clipping.

In embodiment 1, our telescopic mechanism is a soft rubber strip 7, the top of the soft rubber strip 7 is clamped at the bottom of the side plate of the door-shaped plate 1, and the bottom of the soft rubber strip 7 is clamped at the top of the bottom plate 2. This clamping mechanism all is through the draw-in groove joint, and 7 tops of soft rubber strip and bottom all are equipped with trapezoidal draw-in groove 13, and the curb plate bottom of door shaped plate 1, 2 tops of bottom plate all set up with draw-in groove 14 that cooperate with, and trapezoidal draw-in groove 14 is realized connecting to trapezoidal draw-in groove 13 card. The soft rubber strip 7 is stretched through the self deformation capacity.

Because soft rubber strip 7 can take place deformation, trapezoidal card strip 13 can lead to trapezoidal card strip 13 to break away from trapezoidal draw-in groove 14 with trapezoidal draw-in groove 14's joint position atress, so in order to prevent that soft rubber strip 7 of looks cavity interior filler in-process from receiving both sides pressure and leading to trapezoidal card strip 13 to break away from trapezoidal draw-in groove 14, we will set up second slide rail 8 on backplate 4, 2 both sides of bottom plate set up the second spout 9 with 8 sliding connection of second slide rail, so, there is backplate 4 restriction in the soft rubber outside of filler process and just can avoid trapezoidal card strip 13 to break away from trapezoidal draw-in groove 14.

Example 2:

compare in embodiment 1, telescopic machanism is the ascending sliding connection mechanism of vertical side in this embodiment 2, 2 both sides of bottom plate are equipped with riser 10, riser 10 top is equipped with flange 11, the curb plate bottom of 1 both sides of door-shaped plate is equipped with dog 12, flange 11 and dog 12 contact back, dog 12 is spacing to flange 11. When the telescopic mechanism is in an extension state, the flange 11 is contacted with the stop 12, as shown in a state before compaction in the attached figure 6 of the specification. The telescopic mechanism is in a contracted state in which the flange 11 is above the stop 12 and away from the stop 12, as shown in the compacted state in figure 6 of the drawings. The telescopic mechanism is more practical, the second slide rail 8 is not needed to be arranged on the guard plate 4, and the second slide grooves 9 are arranged on two sides of the bottom plate 2.

In summary, the following steps:

when the device is used, firstly, the filler is filled in a cavity defined by the door-shaped plate 1, the telescopic mechanism and the bottom plate 2, and in the process, the through hole 3 is ensured to be blocked by the protective plate 4, as shown in the attached figure 3 of the specification. The height of the chamber is about one centimeter greater than the depth of the expansion joint in the extension state of the telescopic mechanism, so that the top of the chamber is about one centimeter higher than the ground after the device is plugged into the expansion joint, and the device is shown in a state before compaction in the attached figure 4 or figure 6 of the specification. The telescopic mechanism is contracted in the subsequent compaction process, the filler in the device is compacted to ensure the density of the filler, and the top surface of the device is flush with the ground, as shown in the figures 4 or 6 of the attached drawings in the specification after compaction. The road crack repairing method greatly shortens the time of the filler in the expansion joint, the filler cannot be scattered on two sides of the expansion joint, and the road crack after expansion joint dust removal can be efficiently and beautifully repaired.

The following should be additionally described in conjunction with the accompanying fig. 7 of the specification:

in the compaction process, because the top plate of the door-shaped plate 1 is higher than the road surface by about 1 cm, if the compression roller 15 is adopted to press the other side from one side of the device, the other side of the device can be tilted. Therefore, in order to prevent the other side of the device from tilting, a limit pressure plate 16 is arranged on the compacting machine, and the limit pressure plate 16 is positioned in front of the compression roller 15 and just contacts with the top plate of the door-shaped plate 1 which is higher than the road surface without generating pressure. Therefore, the compression roller 15 can avoid warping due to the limiting effect of the limiting pressure plate 16 in the compaction process.
