Description

Technical Field

[0001] This utility model relates to the field of bridge and tunnel pavement maintenance technology, and in particular to a structure for reinforcing longitudinal cracks in bridge and tunnel pavements. Background Technology

[0002] Cracks in bridge and tunnel pavements are a common problem in engineering projects. They not only affect the aesthetics and durability of the structure, but in severe cases, can also threaten the safe use of roads and bridges. Based on their causes and characteristics, bridge and tunnel pavement cracks can be classified into various types, such as load cracks, temperature cracks, shrinkage cracks, alkali-aggregate reaction cracks, and steel corrosion cracks. Different types of cracks have different characteristics and manifestations. For example, load cracks often appear in tension zones, shear zones, or areas subject to severe vibration, while temperature cracks expand or close with temperature changes.

[0003] After a long period of use, bridge and tunnel pavements may develop cracks due to factors such as load and temperature changes. These cracks pose certain safety hazards and require reinforcement. Currently, repair materials are often directly filled into the cracks, but these materials cannot fully bond with the tunnel, and cracks reappear after a period of time, resulting in poor repair effectiveness. Therefore, a reinforcement structure for longitudinal cracks in bridge and tunnel pavements is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing methods for filling and reinforcing road surface cracks, which often involve directly filling the cracks with repair materials. However, the repair materials cannot fully bond with the tunnel, and cracks will still appear on the road surface after a period of time, resulting in poor repair effects. Therefore, this utility model proposes a structure for reinforcing longitudinal cracks in bridge and tunnel road surfaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A structure for reinforcing longitudinal cracks in bridge and tunnel pavements includes a pavement body with an installation groove. A first mounting seat is provided in the installation groove, and a second mounting seat is provided on one side of the first mounting seat. A connecting rod is fixedly connected to one side of the first mounting seat. A rectangular block is fixedly connected to the top of the first and second mounting seats.

A first casting plate is provided above the first and second mounting seats, and second casting plates are provided at both ends of the first casting plate. Casting holes are provided on both the first and second casting plates.

[0006] Preferably, the snap-fit ​​mechanism includes a spring, a snap-fit ​​block, and a first limiting block. One end of the spring is fixedly connected to the snap-fit ​​block, the bottom of the snap-fit ​​block is fixedly connected to the first limiting block, a support block is fixedly connected to the bottom of the first casting plate, a snap-fit ​​groove is provided on one side of the support block, a limiting groove is provided at one end of the first rectangular groove, the first limiting block is slidably connected to the limiting groove, and one end of the spring is fixedly connected to the limiting groove.

[0007] Preferably, a receiving cavity is provided on one side of the second mounting base, and a second limiting block is fixedly connected to one end of the connecting rod. One end of the connecting rod is located inside the receiving cavity, and the second limiting block is slidably connected to the receiving cavity.

[0008] Preferably, the first mounting base and mounting groove have a first fixing hole, and the second mounting base and mounting groove have a second fixing hole. A first fixing bolt is connected in the first fixing hole, and a second fixing bolt is connected in the second fixing hole.

[0009] Preferably, the top of the first casting slab is provided with a second rectangular groove, and a connecting plate is fixedly connected to one side of the second casting slab. The connecting plate is located in the second rectangular groove, and the second rectangular groove and the connecting plate are provided with a third fixing bolt.

[0010] Preferably, the two sides of the first casting plate are in contact with the second casting plate, and the sidewalls of the first casting plate and the second casting plate are in contact with the mounting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, this equipment involves fixing the first and second mounting seats into the mounting groove. Then, using a snap-fit ​​mechanism, the first casting plate is snapped onto the first and second mounting seats. Next, using a connecting plate and a second rectangular groove, the second casting plate is fixed to both ends of the first casting plate with fixing bolts, ensuring that it completely covers the mounting groove. Finally, repair material is filled into the casting hole to repair the crack. Compared to directly filling the crack with repair material, this method has stronger structure, higher load-bearing capacity, and better reinforcement and repair effect. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-6 A structure for reinforcing longitudinal cracks in bridge and tunnel pavement includes a pavement body 1, an installation groove 2 on the pavement body 1, a first installation seat 3 inside the installation groove 2, a second installation seat 4 on one side of the first installation seat 3, a connecting rod 5 fixedly connected to one side of the first installation seat 3, a rectangular block 6 fixedly connected to the top of the first installation seat 3 and the second installation seat 4, a first rectangular groove 7 on the top of the rectangular block 6, a snap-fit ​​mechanism inside the first rectangular groove 7, a first casting plate 8 above the first installation seat 3 and the second installation seat 4, a second casting plate 9 at both ends of the first casting plate 8, and casting holes on both the first casting plate 8 and the second casting plate 9.

[0016] Furthermore, the snap-fit ​​mechanism includes a spring 10, a snap-fit ​​block 11, and a first limiting block 12. One end of the spring 10 is fixedly connected to the snap-fit ​​block 11, the bottom of the snap-fit ​​block 11 is fixedly connected to the first limiting block 12, a support block 13 is fixedly connected to the bottom of the first casting plate 8, a snap-fit ​​groove 14 is provided on one side of the support block 13, a limiting groove is provided at one end of the first rectangular groove 7, the first limiting block 12 is slidably connected to the limiting groove, and one end of the spring 10 is fixedly connected to the limiting groove. A receiving cavity 15 is provided on one side of the second mounting base 4. A second limiting block 16 is fixedly connected to one end of the connecting rod 5. One end of the connecting rod 5 is located inside the receiving cavity 15, and the second limiting block 16 is slidably connected to the receiving cavity 15.

[0017] In this process, an installation groove 2 is opened at the crack in the road surface to ensure that the installation groove 2 completely covers the crack. According to the width of the installation groove 2, the connecting rod 5 is pulled out from the receiving cavity 15, and the distance between the first mounting seat 3 and the second mounting seat 4 is adjusted so that the side wall of the first mounting seat 3 and the side wall of the second mounting seat 4 both abut against the installation groove 2. Then, it is fixed by the first fixing bolt and the second fixing bolt. The first casting plate 8 is placed on the first mounting base 3 and the second mounting base 4. The support block 13 enters the first rectangular groove 7. The support block 13 slides along the inclined side of the snap-fit ​​block 11 and continues to press down on the first casting plate 8. The spring 10 contracts until the bottom of the first casting plate 8 is in contact with the top of the rectangular block 6. Under the elastic action of the spring 10, the snap-fit ​​block 11 snaps into the snap-fit ​​groove 14, thereby limiting the first casting plate 8 and preventing the first casting plate 8 from popping out of the mounting groove 2 due to a large impact force during casting. The first limiting block 12 is used to limit the locking block 11 to prevent the locking block 11 from failing to accurately engage into the locking groove 14 due to the bending of the spring 10.

[0018] Furthermore, the first mounting base 3 and the mounting groove 2 are provided with a first fixing hole 17, and the second mounting base 4 and the mounting groove 2 are provided with a second fixing hole 18. A first fixing bolt is connected in the first fixing hole 17, and a second fixing bolt is connected in the second fixing hole 18. The top of the first casting plate 8 is provided with a second rectangular groove 19, and a connecting plate 20 is fixedly connected to one side of the second casting plate 9. The connecting plate 20 is located in the second rectangular groove 19, and the second rectangular groove 19 and the connecting plate 20 are provided with a third fixing bolt.

[0019] In this process, a suitable second pouring plate 9 is selected according to the length of different installation slots 2 and placed between the first pouring plate 8 and the installation slot 2. The connecting plate 20 is inserted into the second rectangular slot 19 and fixed with the third fixing bolt to prevent the second pouring plate 9 from popping out of the installation slot 2 due to the large impact force during pouring.

[0020] Furthermore, the two sides of the first casting plate 8 are attached to the second casting plate 9, and the side walls of the first casting plate 8 and the second casting plate 9 are attached to the mounting groove 2.

[0021] In this process, it is ensured that the first pouring plate 8 can completely cover the installation groove 2, and finally, repair material is filled from the pouring hole to repair the crack.

[0022] The working principle of this utility model: By opening an installation groove 2 at the crack in the road surface, ensuring that the installation groove 2 completely covers the crack, and adjusting the distance between the first mounting seat 3 and the second mounting seat 4 according to the width of the installation groove 2, the first mounting seat 3 and the second mounting seat 4 are fixed into the installation groove 2 by the first fixing bolt and the second fixing bolt. Subsequently, the first casting plate 8 is placed on the first mounting base 3 and the second mounting base 4. The support block 13 enters the first rectangular groove 7. The support block 13 slides along the inclined side of the snap-fit ​​block 11 and continues to press down on the first casting plate 8. The spring 10 contracts until the bottom of the first casting plate 8 is in contact with the top of the rectangular block 6. Under the elastic action of the spring 10, the snap-fit ​​block 11 snaps into the snap-fit ​​groove 14, thereby limiting the first casting plate 8. Then, according to the length of different installation slots 2, select a suitable second pouring plate 9 and place it between the first pouring plate 8 and the installation slot 2. The connecting plate 20 enters the second rectangular slot 19 and is fixed with the third fixing bolt to ensure that it can completely cover the installation slot 2 in conjunction with the first pouring plate 8. Finally, fill the pouring hole with repair material to repair the crack.
