Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a bridge crack grouting reinforcement device. Background Art

[0002] Bridge cracks are fractures or gaps that appear on or within bridge structures over the long term due to factors such as material aging, loads, temperature fluctuations, and foundation settlement. These cracks not only affect the aesthetics of the bridge but also, more importantly, weaken its load-bearing capacity and durability, potentially leading to safety accidents. Therefore, timely detection and effective treatment of bridge cracks are crucial measures to ensure safe bridge operation.

[0003] Although the existing bridge crack grouting reinforcement technology can initially fill cracks, its method is relatively traditional, that is, concrete is poured directly into the cracks, and the surface of the concrete after solidification is directly exposed on the bridge deck. This not only easily causes driving bumps, affecting driving safety and comfort, but also is prone to cracking, peeling, etc. due to long-term direct exposure to the natural environment, wind and rain erosion and temperature changes, thereby accelerating material aging, reducing the durability of the reinforcement effect, and posing a potential threat to the overall structural safety of the bridge. For this reason, we propose a bridge crack grouting reinforcement device. Utility Model Content

[0016] Preferably, the grouting pipes are provided in plurality, which are divided into two groups, and the two groups are arranged opposite to each other.

[0017] Preferably, the guide tubes and guide holes are provided in two groups, the two groups are combined and connected, and the bottoms of the two guide tubes are provided in a conical shape.

[0018] Preferably, the inner ends of the two pads are inclined, the bottom ends of the two guide tubes extend between the two pads, and the size of the bottoms of the two guide tubes is smaller than the size of the gap formed between the two pads.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1-4 As shown, in this embodiment, a bridge crack grouting reinforcement device includes a backing plate 1, and two backing plates 1 are provided with a grouting reinforcement assembly 2 for grouting and reinforcement;

[0031] In this embodiment, the grouting reinforcement assembly 2 includes a top plate 21, a fixing dowel 22, a grouting pipe 23 and a diversion pipe 24. The top plate 21 is set on the base plate 1; the fixing dowel 22 passes through the top plate 21 and the base plate 1, and the top plate 21 and the base plate 1 are fixedly connected by the fixing dowel 22; the grouting pipe 23 is fixedly connected to the bottom of the top plate 21, and a grouting port 231 is provided at the top of the grouting pipe 23; the grouting port 231 is parallel to the top surface of the top plate 21, and a plurality of leakage grooves 232 are opened through the bottom of the grouting pipe 23; the diversion pipe 24 is fixedly connected to the bottom surface of the top plate 21, and a plurality of diversion holes 241 are opened at the bottom of the diversion pipe 24. The diversion pipe 24 and the diversion port are provided to guide the concrete, so that the concrete is introduced into the cracks for filling.

[0032] Specifically, grooves are chiseled around the cracks in the bridge deck for placing the device, and then two pads 1 are placed in the grooves, and then the top plate 21 is placed on the two pads 1, and then multiple fixing drills 22 are drilled into the top plate 21 and the pads 1, and then drilled into the bridge for fixation, and then concrete is poured into the grouting pipe 23 through multiple grouting ports 231. Part of the concrete leaks out from the multiple leakage grooves 232 and is used to fix the multiple fixing drills 22 and between the top plate 21 and the pads 1. Since the concrete is poured between the top plate 21 and the pads 1, it will not be directly exposed to the outside, thereby reducing the damage caused by long-term direct exposure to the natural environment, wind and rain erosion and temperature changes.

[0033] Example 2

[0034] like Figure 1-4 As shown, in this embodiment, the top ends of the multiple fixing dowels 22 are parallel to the top surface of the top plate 21; the guide tubes 24 and the guide holes 241 are arranged in two groups, and the two groups are connected together. The bottoms of the two guide tubes 24 are arranged in a conical shape, and the two guide tubes 24 are respectively connected to the two groups of grouting pipes 23; the inner ends of the two pads 1 are arranged at an angle, and the bottom ends of the two guide tubes 24 extend between the two pads 1. The size of the bottom of the two guide tubes 24 is smaller than the size of the gap formed between the two pads 1. The two guide tubes 24 can guide the concrete without opening cracks.

[0035] Specifically, since multiple grouting ports 231 are parallel to the top surface of the top plate 21, the tops of multiple fixing rods 22 are parallel to the top surface of the top plate 21, and the top surface of the top plate 21 is parallel to the bridge deck, the bridge deck, the top plate 21, the fixing rods 22 and the grouting ports 231 are parallel to each other to ensure smoothness and avoid bumps.

[0036] like Figure 1 As shown, further, a plurality of grooves 211 are provided on the top surface of the top plate 21, and the plurality of grooves 211 are respectively connected to a plurality of grouting ports 231. By providing a plurality of grooves 211, the concrete can be guided to be poured into the grouting ports 231. In addition, the plurality of grooves 211 are parallel to the direction of vehicle travel, and therefore will not affect the smoothness of the device.

[0037] Working principle: First, a groove is dug around the crack of the bridge deck for placing the device, and then two pads 1 are placed in the groove, and then the top plate 21 is placed on the two pads 1, and then multiple fixing drills 22 are drilled into the top plate 21 and the pad 1, and then drilled into the bridge for fixation, and then concrete is poured into the grouting pipe 23 through multiple grouting ports 231. Part of the concrete leaks out from the multiple leakage grooves 232, which is used to fix the multiple fixing drills 22 and between the top plate 21 and the pad 1.
