Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a bridge crack reinforcement structure. Background Technology

[0002] During the long-term use of bridges and roads, cracks of varying degrees may occur due to localized overpressure or prolonged direct sunlight. To ensure the safety of bridges and roads, it is necessary to reinforce the cracks on the bridges in a timely manner.

[0003] The current bridge crack reinforcement structure is mainly composed of reinforcement steel plates with bolt holes. During construction, the crack is first cleaned and a groove is chiseled along its circumference. The reinforcement steel plate is then placed on top of the groove and fixed to the bottom of the groove with bolts. The pre-set pouring holes on the steel plate are used to inject grout, so that the grout fully fills the gap between the crack and the steel plate and overflows the groove, ultimately forming a reinforcement layer that is flat with the original road surface.

[0004] When injecting grout between the reinforcing steel plate and the crack through the pouring hole, problems such as incomplete filling and large voids in the grout can easily occur, thus affecting the overall reinforcement effect of the crack. To address these issues, a bridge crack reinforcement structure is proposed. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model is provided: a bridge crack reinforcement structure, including a steel plate 1, the steel plate 1 is a high-strength steel plate, a plurality of injection holes 2 are opened on the surface of the steel plate 1, the injection holes 2 are used to inject sealing grout, a housing 6 is fixedly connected to the top of the steel plate 1 by screws 7, an injection assembly is installed at the bottom of the steel plate 1, a vibration assembly is installed at the bottom of the steel plate 1, and a drive assembly is installed at the top of the steel plate 1. The adhesive injection assembly includes an adhesive injection tube 10, which is fixedly connected to the bottom of the steel plate 1 and located inside the adhesive injection hole 2. The adhesive injection tube 10 passes through and is fixed inside the adhesive injection hole 2. The adhesive injection tube 10 is used to inject grout into the crack. The bottom of the adhesive injection tube 10 is fixedly connected to the adhesive injection tube 24 via a hose 12. The hose 12 is a pressure-resistant hose. The bottom of the adhesive injection tube 24 is fixedly connected to the adhesive injection tube 35 via a hose. The bottom of the adhesive injection tube 35 is fixedly connected to the adhesive injection tube 46 via a hose. Holes 13 are opened on the surfaces of the adhesive injection tubes 10, 24, 35, and 46. The several holes 13 can ensure that the adhesive can seep out evenly under pressure, thereby fully filling the crack from the depth to the surface.

[0013] Reference Figure 2 and Figure 5 The vibration assembly includes multiple connecting shafts 21, all of which are rotatably connected inside the steel plate 1. Vibration rods 9 are rotatably connected to the outer sides of the multiple connecting shafts 21. The vibration rods 9 are used to transmit multidimensional excitation forces during movement. Eccentric shafts 22 are fixedly connected to the bottom of the multiple connecting shafts 21. The eccentric shafts 22 are fixedly connected to the inner side of the vibration rods 9. When the connecting shafts 21 rotate under drive, the eccentric shafts 22 will generate periodic eccentric forces, thereby driving the vibration rods 9 to agitate the internal slurry. Through the vibration of the vibration rods 9, the flow, penetration and compaction of the injected adhesive are effectively promoted, avoiding the generation of air bubbles and cavities, and improving the reliability and durability of crack reinforcement.

[0014] Reference Figures 3-6The drive assembly includes a housing 6, inside which a motor 17 is fixedly connected. The motor 17 is the main drive component. An eccentric shaft 18 is fixedly connected to the output end of the motor 17. The eccentric shaft 18 is rotatably connected to the top of the steel plate 1, thus converting the rotational motion of the motor 17 into eccentric vibration in a plane. A straight rod 19 is rotatably connected to the end of the eccentric shaft 18 away from the output end of the motor 17. A connecting rod 20 is rotatably connected to one end of the straight rod 19. A mounting plate 8 is fixedly connected to one end of the connecting rod 20, thus converting the rotational motion of the eccentric shaft 18 into the horizontal reciprocating motion of the mounting plate 8. Multiple racks 15 are fixedly connected to one side of the mounting plate 8. Multiple gears 16 are rotatably connected to the top of the steel plate 1. The gears 16 mesh with the racks 15. The back-and-forth movement of the racks 15 drives the gears 16 to rotate. Each of the multiple gears 16 has a slot 23 at its bottom. Each of the multiple connecting shafts 21 has a locking block fixedly connected to its top. 11. Multiple slots 23 and multiple blocks 11 engage with each other. When the gear 16 rotates, the motion is precisely transmitted to the connecting shaft 21 below through the engagement of the slots 23 and blocks 11, thereby driving the vibrating rod 9 to vibrate and rotate synchronously. The top of the steel plate 1 is fixedly connected to the fixing plate 4 by screws 7. The fixing plate 4 serves as a guide and support, and restricts the movement of the rack 15. The rack 15 is slidably connected to the bottom of the fixing plate 4. Multiple high-strength bolts 5 are threaded in the middle of the steel plate 1. The multiple high-strength bolts 5 penetrate the structural layer and firmly anchor the entire reinforcement system to the bridge crack. Each of the multiple high-strength bolts 5 has a glue injection hole 2 3 in the middle. The glue injection hole 2 3 can be used to inject grout into the interior to make it more stable. Multiple grooves 14 are opened at the bottom of the steel plate 1. The grooves 14 are used to increase the friction with the bridge during grouting, significantly improving the interface bonding performance and the reliability of the overall reinforcement.

[0015] Working principle: First, the crack is cleaned, and a groove of appropriate size is chiseled along its circumference. After cleaning the groove, the glue injection tube 10 on the steel plate 1 and the vibrating rod 9 are inserted into the crack. A layer of grout is applied to the surface of the groove. Then, the steel plate 1 is placed on top of the groove and fixed to the bottom of the groove with high-strength bolts 5. An appropriate amount of grout is injected into the groove through the second glue injection hole 3 to make the high-strength bolts 5 fix the steel plate 1 more tightly. Then, grout is injected into the glue injection tube 10 through the first glue injection hole 2. The grout will then enter the crack through the holes 13 on the glue injection tubes 10, 24, 25, 26, and 26 connected by the hose 12. Due to the connection through the hose 12, the glue injection tube 10 can be inserted deeper.

[0016] Then, start motor 17. Motor 17 drives eccentric shaft 18 to rotate, causing straight rod 19 connected to eccentric shaft 18 to drive connecting rod 20 to move back and forth. Connecting rod 20 drives mounting plate 8 connected to multiple racks 15 to move back and forth within fixed plate 4. Then, racks 15 drive gear 16 to rotate, and connecting shaft 21 connected through gear 16 can rotate, driving eccentric shaft 22 to rotate inside vibrating rod 9. This allows vibrating rod 9 to vibrate the newly entered slurry at different positions inside the gap. Finally, unscrew screws 7 on steel plate 1 to remove all parts from steel plate 1, making steel plate 1 a reinforced layer that is flat with the original road surface.
