Description

Technical Field

[0001] The present application relates to the technical field of bridge pier protection, and specifically to a bridge pier protection structure for a wading bridge. Background Art

[0002] A bridge pier is a structure that supports the bridge span structure and transfers the load to the foundation. The most common piers for bridges built in rivers are column piers. However, when passing ships pass between the piers, if the operators are not familiar with the water conditions, it is easy for the ships to collide with the piers. Therefore, it is usually necessary to set up protective structures on the piers.

[0003] A Chinese utility model patent with publication number CN220579788U discloses a pier protection structure, including a pier body, an outer wall of the pier body is provided with a protective cylinder, a front end of the protective cylinder is provided with a backflow component for diverting flow, an outer wall of the protective cylinder is provided with an anti-collision pad, a buffer component for buffering is provided inside the anti-collision pad, and a fixed block is fixedly connected to the upper end of the pier body. The utility model can protect the pier body by providing the protective cylinder, and can reduce the water flow pressure brought by the upstream while ensuring the normal circulation of the water flow by providing the diversion component. By providing a connecting column made of rubber material, a part of the impact force generated by the collision of the ship can be absorbed when the connecting column is hit, and by providing the buffer component, the buffer component can play a certain buffering role when the connecting column is hit, so as to avoid the pier body being directly hit and damaged, thereby generating a safety hazard.

[0004] The device is provided with a protective cylinder, an anti-collision pad is provided on the outer wall of the protective cylinder, and a buffer component for buffering is provided inside the anti-collision pad. When performing protection operations on bridge piers, workers set the protective cylinder on the piers. When a ship collides, it will impact the connecting column and the protective cylinder. However, the position of the protective cylinder on the pier is fixed. When the water depth changes, the protective cylinder is inconvenient to rise and fall accordingly. Therefore, the protection capability is not high and the scope of application is small. Utility Model Content

[0005] In view of the problem of small application scope in the prior art, the utility model specially provides a pier protection structure of a wading bridge.

The balls arranged on the inner wall of the pontoon are brought into contact with the bridge piers, so that when the pontoon rises and falls with the water body, the pontoon can be raised or lowered by the rotation of the balls, thereby avoiding direct contact between the inner wall of the pontoon and the bridge piers, thereby ensuring the safety of the equipment.

[0013] Preferably, a light strip is fixedly provided on the baffle, and the light strip can be provided to illuminate the range of the bridge pier to warn operators of passing ships and ensure the safety of the bridge pier.

[0028] In at least one embodiment, the assembling mechanism includes a fixed plate 6 and an insertion rod 601, a group of insertion holes 204 are respectively provided on both sides of the baffle 2, a fixed plate 6 is provided between two adjacent groups of baffles 2, and an insertion rod 601 matched with the insertion hole 204 is fixedly provided at the bottom of the fixed plate 6. When assembling multiple groups of baffles 2, the staff places the fixed plate 6 between two adjacent groups of baffles 2, and then respectively inserts the two groups of insertion rods 601 on the baffle 2 into the insertion holes 204 on one group of baffles 2, thereby realizing the combination of multiple groups of baffles 2, and the operation is convenient.

[0029] In at least one embodiment, the fixing rods 201 are provided in multiple groups and are respectively located at the upper and lower ends of the baffle 2 . The multiple groups of fixing rods 201 are used to limit the baffle 2 at multiple points, thereby ensuring the stability of the movement of the baffle 2 .

[0030] In at least one embodiment, a plurality of groups of grooves are arranged at intervals on the inner wall of the pontoon 1, and balls 5 are rotatably arranged in the grooves. The balls 5 arranged on the inner wall of the pontoon 1 are brought into contact with the bridge piers, so that when the pontoon 1 rises and falls with the water body, the pontoon 1 can be raised and lowered by the rotation of the balls 5, thereby preventing the inner wall of the pontoon 1 from directly contacting the bridge piers, thereby ensuring the safety of the equipment.

Multiple groups of baffles 2 are arranged on the outside of the pontoon 1. When the hull collides with the pier, it will first collide with the baffle 2. The circumferential multiple groups of baffles 2 guide the forward direction of the hull when it collides to avoid continuous frontal collisions. After the baffle 2 is hit, the spring 3 is compressed to buffer the impact force on the baffle 2 to avoid instantaneous collisions on the piers. The fixing rod 201 on the baffle 2 limits the baffle 2 to ensure the stability of the movement of the baffle 2, and the multiple groups of baffles 2 can be combined through the assembly mechanism, so that the multiple groups of baffles 2 can jointly buffer the collision of the ship and improve the protection performance. When the water depth changes, the pontoon 1 will drive the baffle 2 to rise and fall synchronously with the change of the water body, ensuring effective protection of the piers and improving the scope of application.
