Description

Technical Field

[0001] A bridge pier protection structure is used for bridge pier protection and belongs to the technical field of bridge pier protection structure. Background Technology

[0002] Pier protection is a crucial aspect of bridge engineering, primarily preventing water erosion, impact from drifting debris, foundation erosion, and freeze-thaw damage.

[0003] In existing technologies, common bridge pier protection methods combine riprap, Reno mattresses, and concrete pouring. The riprap layer quickly fills scour pits, dispersing the impact of water flow; the Reno mattress provides a flexible, erosion-resistant surface layer to adapt to foundation deformation; and the concrete structure serves as a high-strength core to withstand extreme water flow or debris impacts. This composite protection technology, combining riprap, Reno mattresses, and concrete, with its layered design that balances rigidity and flexibility, can cope with complex hydrogeological conditions. However, it presents the following technical challenges: The use of steel wire to splice adjacent cages and cages with the mesh cover in Reno mattresses is inefficient and can easily injure construction workers, resulting in low construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge pier protection structure to solve the problem of low construction efficiency caused by using steel wire splicing for adjacent gabions and gabions and gabion covers on Reno mattresses, which also easily injures construction workers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A bridge pier protection structure includes a Reno mattress with a net cover laid around the bridge pier, crushed stone and fragments installed sequentially in the Reno mattress, and concrete poured on the crushed stone, fragments and Reno mattress. The Reno mattress includes multiple gabions and a fixing structure connecting two gabions and each gabion and the net cover.

[0006] Furthermore, the fixing structure includes a clamping member, a connecting structure that slides with the clamping member, and a nut that is threadedly fixed to the connecting structure with the clamping member.

[0007] Furthermore, the clamping member includes an annular elastic clamping piece with an opening, a threaded rod that engages with a nut on one side of the opening of the annular elastic clamping piece, and an inclined guide plate on the other side of the opening that guides the clamping part into the annular elastic clamping piece.

[0008] Furthermore, the connection structure includes a connecting plate that closes the opening of the annular elastic clip, and a sliding groove provided on the connecting plate that slides in cooperation with the threaded rod.

[0009] Furthermore, the width of the inclined guide plate is greater than that of the groove, and the inclined guide plate is in contact with and engaged with the connecting plate.

[0010] Furthermore, the inclined guide plate cooperates with the connecting plates on both sides of the slide groove; or the inclined guide plate cooperates with the connecting plate on one side of the slide groove.

[0011] Furthermore, a rubber pad is provided on the connecting plate on the mating side of the inclined guide plate.

[0012] Compared with the prior art, the advantages of this utility model are: I. This utility model uses a fixed structure to fix two pairs of net cages, each net cage and net cover, which facilitates quick splicing and improves construction efficiency. At the same time, it is easy to firmly form a whole after the net cages and net covers are fixed. This not only facilitates the installation of gravel and fragments after the net cages are fixed, but also helps the net cages and net covers to fix the gravel and fragments in the net cages, thereby improving the protection effect of the bridge piers. Second, the fixing structure in this utility model uses clamping parts to clamp the two net cages, each net cage and the net cover, and then uses each clamping part and nut to fix them on the connecting structure to form an integral connection. This not only makes fixing convenient, but also facilitates fixing the splicing position. 3. The clamping component in this utility model uses an inclined guide plate to guide the connecting rod or steel wire on the edge of the net box or the steel wire on both net boxes into the annular elastic clamp for initial fixation, which is conducive to matching the initially fixed net box and net cover with the connecting structure. IV. The connection structure in this utility model has a groove on the connection plate, which facilitates the cooperation with clamping parts at different positions on the same plane and closes the opening of the clamping parts. This not only opens up the connection to avoid bending, but also helps to firmly fix the connection sides together. 5. The present invention limits the width of the inclined guide plate to be greater than that of the groove. The purpose is to facilitate the inclined guide plate to cooperate with each side of the connecting plate to close the opening of the annular elastic clip. At the same time, it is beneficial for the annular elastic clip to be pressed by force to squeeze the steel wire or connecting rod placed in the annular elastic clip, so as to firmly fix the connection. VI. The purpose of setting a rubber pad on the connecting plate in this utility model is to prevent the inclined guide plate from directly engaging with the connecting plate and easily shifting under force.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0022] Example 1 To address the problem of low construction efficiency caused by using steel wire to splice adjacent gabions and gabions to the gabion cover in Reno mattress construction, which is both inefficient and prone to injuring construction workers, the following measures were taken. Figure 1-6 As shown, a bridge pier protection structure is provided, including a Reno mattress with a mesh cover laid around the bridge pier, crushed stone and fragments (existing, not shown in the figure) installed sequentially in the Reno mattress, and concrete poured on the crushed stone, fragments and Reno mattress. The Reno mattress includes multiple wire mesh cages 1 and a fixing structure 3 connecting two wire mesh cages 1, each wire mesh cage 1 and the mesh cover 2.

[0023] In practice, when bridge pier protection is required, the Reno mattresses and their covers are transported to the designated location, the bent mesh cages are unfolded, and adjacent mesh cages are fixed and spliced ​​together using fixing structure 3. Finally, the mesh cages from the Reno mattress are laid around the bridge pier, and then gravel and debris are filled into the mesh cages. The covers are then fixed to the mesh cages using the fixing structure. After fixing, concrete is poured to form the final structure protecting the bridge pier. This embodiment uses a fixing structure to secure each pair of mesh cages, each mesh cage, and the covers, facilitating rapid splicing and improving construction efficiency. It also ensures that the fixed mesh cages and covers are firmly integrated, which not only facilitates the installation of gravel and debris after the mesh cages are fixed, but also helps the mesh cages and covers retain the gravel and debris within the mesh cages, thus improving the pier protection effect.

[0024] Example 2 Based on Embodiment 1, the fixing structure 3 includes a clamping member 4, a connecting structure 5 that slides with the clamping member 4, and a nut 6 that is threadedly fixed to the connecting structure 5 with the clamping member 4. The fixing structure clamps two net cages, each net cage and net cover through the clamping member, and then fixes each clamping member and nut to the connecting structure to form an integral connection. This not only makes fixing convenient, but also facilitates fixing the splicing position.

[0025] The clamping component 4 includes an annular elastic clamping piece 7 with an opening, a threaded rod 8 that mates with a nut 6 on one side of the opening of the annular elastic clamping piece 7, and an inclined guide piece 9 on the other side of the opening that guides the clamping part into the annular elastic clamping piece. The clamping component guides the connecting rod or wire on the edge of the net cage or the wire on both net cages into the annular elastic clamping piece for initial fixation through the inclined guide piece, which is beneficial for the initial fixation of the net cage and net cover to match the connecting structure.

[0026] The connecting structure 5 includes a connecting plate 10 that closes the opening of the annular elastic clamp 7, and a sliding groove 11 on the connecting plate 10 that slides with the threaded rod 8. By setting the sliding groove on the connecting plate, the connecting structure can easily cooperate with clamping parts at different positions in the horizontal direction and close the opening of the clamping parts. This not only can open up the connection to avoid bending, but also helps to firmly fix the connecting sides together.

[0027] In practice, by holding the threaded rod 8, two or more steel wires or connecting rods that need to be clamped are initially fixed by passing them through the opening of the annular elastic clamp 7 through one side of the inclined guide plate 9. Then, the threaded rod 8, which is located on the same plane, is passed through the sliding groove 11 on the connecting plate 10. The position of the threaded rod 8 is then adjusted to ensure that the connecting side is opened. Then, the nut is used to cooperate with the threaded rod 8 to make the inclined guide plate 9 contact the connecting plate and apply force to the annular elastic clamp 7 to compress the structure inside the annular elastic clamp 7. This not only fixes the clamping part 4 to the connecting plate, but also firmly fixes the splicing position.

[0028] The fixed structure 3 in this case is also conducive to splicing in different directions and positions.

[0029] Example 3 Based on Embodiment 2, the width of the inclined guide plate 9 is greater than that of the slide groove 11, and the inclined guide plate 9 contacts and engages with the connecting plate 10. The width of the inclined guide plate is limited to be greater than that of the slide groove. This is to facilitate the inclined guide plate's engagement with each side of the connecting plate to close the opening of the annular elastic clamp, and simultaneously to allow the annular elastic clamp to compress the steel wire or connecting rod placed within it, thus firmly fixing the connection. The inclined guide plate 9 engages with the connecting plates 10 on both sides of the slide groove 11; or the inclined guide plate 9 engages with the connecting plate 10 on one side of the slide groove 11. The inclined guide plates 9 on the clamping members located at both ends of the connecting plate can also engage with the connecting plates at both ends.

[0030] Example 4 Based on Embodiment 3, a rubber pad 12 is provided on the connecting plate 10 on the mating side of the inclined guide plate 9. The purpose of providing the rubber pad on the connecting plate is to prevent the inclined guide plate from directly mating with the connecting plate, which could easily cause displacement under force.
