Advantages of widely popularizing the use of steel corrugated culvert pipes in national highways, provincial highways and second-class highway 1)Strong adaptability to foundation deformation, low requirements for foundation bearing capacity and flatness, and actual project cost similar to or lower than bridges and culverts of the same span.

　　2)The short construction period is a clear advantage, as civil engineering and pipe installation can be implemented separately and then assembled as a whole.

　　3)Centralized production in the factory is not affected by the environment, which is beneficial for reducing costs and controlling quality.

　　4)Easy on-site installation without the need for large equipment.

　　5)Resolve the problem of damage to concrete structures of bridges and culverts caused by frost in cold northern regions.

　　6)Reducing or completely abandoning the use of conventional building materials such as cement, yellow sand, stones, and wood has far-reaching environmental implications.

　　7)The structural stress situation is reasonable, the load distribution is uniform, and it has a certain degree of deformation resistance.

　　8)Adopting standardized design, simple production and design, and short production cycle.

　　9)Beneficial for improving the interface between soft soil foundation structures and embankments“offset”Phenomenon, improve driving comfort and safety, reduce post work operation and maintenance costs.

　　10)Steel corrugated culvert pipes have good road performance, especially in terms of low foundation requirements, simple construction, quick installation, and greatly shortened construction period, which cannot be compared to ordinary culvert pipes. They will play a positive role in highway reconstruction projects and roadbed maintenance projects.
