Description

Technical Field

[0001] The utility model relates to the technical field of corrugated steel pipe reinforcement, and specifically relates to an external truss strengthening device for corrugated steel pipes. Background Technique

[0002] A corrugated steel pipe is a steel pipe with a special shape, having a wavy surface, thus getting its name. It is made of high-quality steel through a series of processing techniques and is widely used in fields such as construction, municipal engineering, transportation, and electricity. The corrugated steel pipe has many unique features, which will be introduced one by one below:

[0003] First of all, the corrugated steel pipe has high strength and corrosion resistance. It is made of high-quality steel and has high compressive and bending resistance after special treatment. In some special environments, such as marine environments or chemical plants where acid-base corrosion is relatively heavy, the corrugated steel pipe can better protect the pipeline, making it not easily corroded and extending its service life;

[0004] Secondly, the corrugated steel pipe has good flexibility and plasticity. Due to its special wavy shape, the corrugated steel pipe has a certain degree of flexibility and can meet the needs of different angles and bending radii. This feature makes the corrugated steel pipe more flexible and convenient in some cases where bending or large changes in connection angles are required. At the same time, the corrugated steel pipe also has strong plasticity and can be processed into various shapes and sizes through molds and machining;

[0005] Thirdly, the corrugated steel pipe has good sealing and waterproof performance. Due to its wavy surface design, the corrugated steel pipe can be sealed by welding or connection during installation, effectively preventing water leakage. In some occasions where waterproof treatment is required, the corrugated steel pipe can provide a more reliable and lasting waterproof effect.

[0006] In addition, the corrugated steel pipe also has good wear resistance and sound absorption performance. In some occasions where it needs to be moved or rubbed frequently, due to its high strength and good wear resistance, the corrugated steel pipe can effectively reduce wear and damage caused by friction. At the same time, the corrugated structure of the internal cavity of the corrugated steel pipe makes it have good sound absorption performance and can provide a quieter environment in some occasions where noise interference needs to be reduced.

[0007] In summary, as a steel pipe with a special shape, the corrugated steel pipe has a wide range of applications in fields such as construction, municipal engineering, transportation, and electricity. Its unique features such as high strength, corrosion resistance, flexibility, plasticity, sealing performance, waterproof performance, wear resistance, and sound absorption performance have played an important role in various application fields. Therefore, when choosing pipeline materials, the corrugated steel pipe is an excellent choice. Whether in the design, construction, or use process, it can provide users with a more reliable and lasting solution.

[0008] At present, I-beams are generally used to strengthen the inside of corrugated steel pipes. However, the contact surface between the I-beam and the corrugated section is too small to completely conduct the pressure received, resulting in a large gap between the actual strengthening effect and the theoretical strengthening effect. Therefore, an external truss strengthening device for corrugated steel pipes is needed to improve the above problems. Content of the Utility Model

[0009] In order to solve the problem that I-beams are generally used to strengthen the inside of corrugated steel pipes at present, but the contact surface between the I-beam and the corrugated section is too small to completely conduct the pressure received, resulting in a large gap between the actual strengthening effect and the theoretical strengthening effect, the purpose of the present utility model is to provide an external truss strengthening device for corrugated steel pipes to solve the problems raised in the above background technology.

Instead, the bolt should be loosened according to the size of the expansion amount. The expansion joint generally has an expansion limit. Otherwise, unlimited expansion will damage the expansion joint. It can not only limit the position, but also prevent additional blind flange force. BRIEF DESCRIPTION OF THE DRAWINGS
