Description

Technical Field

[0001] The utility model relates to the technical field of corrugated culverts, and specifically relates to a connection structure of a corrugated culvert. Background Technique

[0002] A corrugated culvert is a steel structure pipe widely used in traffic engineering such as culverts under highways and railways. It is formed by rolling a corrugated steel plate or assembling corrugated steel sheets into a circular shape, and has remarkable anti-deformation ability and good stress characteristics.

[0003] The existing Chinese patent (Publication No.: CN213389777U) proposes a connection structure of a corrugated culvert. Both sides of the upper fixing part and the lower fixing part are fixedly connected with extension parts along their length directions, namely an upper extension part and a lower extension part respectively. The surfaces of the upper extension part and the lower extension part are in contact with each other. A plurality of fasteners are evenly spaced along their length directions between the upper extension part and the lower extension part. A T-shaped part is also clamped between the upper extension part and the lower extension part. The T-shaped part includes a horizontal part, a vertical part and a rubber pad. The horizontal part is clamped between the upper extension part and the lower extension part, and rubber pads are arranged on both the upper surface and the lower surface of the horizontal part. The vertical part is in an arc structure and a rubber pad is also arranged on the outer side of the vertical part. The vertical part is closely attached to the inner side walls of the upper fixing part and the lower fixing part, and the rubber pad of the vertical part is clamped between the vertical part and the upper fixing part and the lower fixing part.

[0004] The above technical solution limits the upper fixing part and the lower fixing part by using a fastening rod and a fastening nut, making it not easy to separate and avoiding fluid leakage.

[0005] However, the connection structure of the above corrugated culvert cannot be disassembled, which means that once the corrugated culvert is damaged or needs maintenance, it is not convenient to disassemble the damaged part for replacement or repair. And for corrugated culverts in harsh environments or under high load conditions, the inability to repair or replace damaged parts in time may accelerate the performance decline of the entire structure and shorten its overall service life. Therefore, we propose a connection structure of a corrugated culvert. Content of the Utility Model

[0006] The purpose of the utility model is to provide a connection structure of a corrugated culvert to solve the problems raised in the above background technique.
