Description

Technical Field

[0001] The utility model relates to the technical field of corrugated steel pipes, in particular to a truss reinforcement device inside a corrugated steel pipe. Background Technique

[0002] A corrugated steel pipe is a pipe with an outer shape like regular waves, which is mainly made of materials such as carbon steel, stainless steel, steel-lined plastic, and aluminum. This kind of pipe is mainly used in situations where a very small bending radius for non-concentric axial transmission is required, or in irregular turning, telescoping situations, as well as for absorbing the thermal deformation of the pipeline, etc. Corrugated steel pipes have a very wide range of uses, including but not limited to the fields of automatic control and measuring instruments, as well as engineering technology. They are used in situations where a very small bending radius for non-concentric axial transmission is required, or in irregular turning, telescoping, or for absorbing the thermal deformation of the pipeline, etc., or for connecting pipes to pipes or pipes to equipment in situations where it is not convenient to install with fixed elbows.

[0003] However, there are still certain deficiencies in the existing corrugated steel pipe reinforcement devices during use. In order to enhance its pressure-bearing capacity, a reinforcement device needs to be set inside the corrugated steel pipe. Currently, the existing internal reinforcement device generally uses I-beams inside the corrugated steel pipe. However, the contact surface between the I-beam and the corrugated cross-section is too small to completely conduct the received pressure, resulting in a large gap between the actual reinforcement effect and the theoretical reinforcement effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a truss reinforcement device inside a corrugated steel pipe to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:
