Description

Technical Field

[0001] The utility model belongs to the technical field of road maintenance, and more specifically, particularly relates to a road crack reinforcement device. Background Art

[0002] During the process of highway damage, pavement cracks are a relatively common damage phenomenon. The appearance of pavement cracks not only has a greater impact on road construction units and maintenance units, but also affects road driving safety. When cracks and potholes appear on the highway, they must be repaired in time to avoid traffic accidents. The driving speed on the highway is generally relatively fast, and some small vehicles with relatively light weights may even experience vehicle jumping or loss of control instability. Especially at night, because the road conditions cannot be seen clearly, traffic accidents are more likely to occur.

[0003] Based on the above hazards of pavement cracks to vehicle safety, pavement cracks also have many situations. Small surface cracks can be solved with crack tapes, while larger cracks require grouting and asphalt. However, when facing cracks that are very narrow and deep, crack tapes are not very useful, and the cracks will continue to develop deeper. Grouting and asphalt, due to the excessive depth and narrowness of the cracks, and their own viscosity, cannot reach the deep part, which is likely to cause material waste. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a road crack reinforcement device to solve the problems that existing small vehicles pass through cracks unsteadily and most methods cannot handle cracks that are very narrow and deep.

[0005] A road crack reinforcement device of the utility model is achieved by the following specific technical means:

[0006] A road crack reinforcement device includes a reinforcement device; a tooth expander;

[0007] The reinforcement device as a whole presents a T shape, and two fixing piles are respectively arranged on both sides of the upper end of the reinforcement device, and the fixing piles penetrate through the upper and lower surfaces of the reinforcement device; a square groove penetrating through the front and back is opened in the middle of the upper end of the reinforcement device, and a guiding groove is also opened below the square groove. The tooth expander is installed in the guiding groove, and the lower end of the tooth expander is set as an inverted triangle; two rows of through holes are opened on both sides of the lower end of the reinforcement device, and fixing teeth are installed in the lower row of through holes.

[0008] Further, the left and right ends of the fixing device are set as ramp-shaped.

[0009] Further, an inverted T-shaped diversion groove is opened in the middle of the tooth expander.

[0010] Further, chamfers are provided above one end of all the fixing teeth close to the tooth expander.

[0011] Furthermore, connection slots are respectively opened at the front and back of the upper end of the reinforcement device, and connection keys are clamped in the connection slots.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting the T-shaped reinforcement device, when in use, the lower end is inserted into the crack, fixed by the reinforcement piles on both sides of the upper end, and reinforced by the fixed teeth at the lower end, so that deeper fissures can be better fixed.

[0014] 2. By setting the tooth-expanding device with a diversion groove, after the tooth-expanding device is in place, the filler related to the road surface crack is manually conveyed into the diversion groove by the operator, and then enters the crack through the diversion groove, better filling the gap between the reinforcement device and the crack, and avoiding the situation of unsmooth and wasteful entry of the filler.

[0015] 3. By setting the fixed teeth, under the action of the upper tooth-expanding device, the fixed teeth are inserted into the soil on both sides of the crack, making the crack more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following further describes in detail the embodiments of the utility model in conjunction with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0024] Example:

[0025] As shown in Att Figure 1 to Att Figure 5 shown:

[0026] The utility model provides a road crack reinforcement device, including a reinforcement device 1; a tooth expander 3;

[0027] The reinforcement device 1 is integrally T-shaped, and two fixing piles 2 are respectively arranged on both sides of the upper end of the reinforcement device 1, and the fixing piles 2 penetrate through the upper and lower surfaces of the reinforcement device 1; a square groove penetrating through the front and back is opened at the middle position of the upper end of the reinforcement device 1, and a guiding groove 8 is also opened below the square groove. The tooth expander 3 is installed in the guiding groove 8, and the lower end of the tooth expander 3 is in an inverted triangle shape; two rows of through holes are opened on both sides of the lower end of the reinforcement device 1, and fixing teeth 4 are installed in the lower row of through holes.

[0028] Among them, as Figure 1 shown, the left and right ends of the fixator are in a slope shape, which is convenient for the vehicle to pass as smoothly as possible when driving above the fixator.

[0029] Among them, as Figure 5 shown, an inverted T-shaped diversion groove 6 is opened in the middle of the tooth expander 3, which is used for manually conveying grout to the bottom after the tooth expander 3 is in place, so as to better reinforce the crack.

[0030] Among them, as Figure 3 shown, chamfers are provided above one end of all the fixing teeth 4 close to the tooth expander 3, which is used to better insert into the outside soil by means of the force at the inverted triangle at the lower part of the tooth expander 3, so as to increase the stability after fixation.

[0031] Among them, as Figure 1 shown, connection grooves 7 are respectively opened at the front and back of the upper end of the reinforcement device 1, and connection keys 5 are clamped in the connection grooves 7, which are used to fixedly connect multiple reinforcement devices 1 together with the connection keys 5 when the crack is relatively long, so as to conveniently deal with cracks in various situations.

[0032] The specific usage method and function of this embodiment:

[0033] In the utility model, the lower end of the reinforcement device 1 is inserted into the crack by machinery or manually, or the surface of the crack can be cleaned to a position where the upper end of the fixator can be directly placed. When the lower end of the reinforcement device 1 extends into the crack in place, the fixing column 2 is hammered into the ground, and then the tooth expander 3 is pressed downwards, so that the fixing teeth 4 at its lower end extend outwards and are inserted into the soil. Finally, the grout to be poured is introduced into the bottom of the crack through the diversion groove 8 and flows out from the through holes at the lower end of the reinforcement device 1, so as to better reinforce the stability of the crack. When the crack is too long, the connection grooves 7 at the upper end of the reinforcement device 1 can be aligned (the reinforcement device 1 with different angles can be designed according to different actual situations without violating the principle of this design concept to deal with cracks of various shapes), and the connection keys 5 are clamped and fixed to realize the lengthening of the fixation of the crack.

[0034] Where the utility model is not described in detail are all well-known technologies to those skilled in the art.
