The widespread adoption of steel corrugated pipe in highways and secondary roads offers numerous advantages. 1)The ground deformation resistance is strong, with lower requirements for ground bearing capacity and flatness. The actual construction cost of the project is comparable to or lower than that of similar span bridges and culverts.

　　2)Short construction period offers distinct advantages; civil engineering and pipe section installation can be carried out separately, followed by overall assembly.

　　3)The factory is implementing centralized production to ensure environmental neutrality, which is beneficial for cost reduction and quality control.

　　4)Easy on-site installation, no need for large equipment.

　　5)Addressing the issue of frost damage to bridge and culvert concrete structures in cold northern regions.

　　6)Reducing or completely eliminating the use of conventional building materials such as cement, yellow sand, gravel, and wood carries profound environmental significance.

　　7)The structural load-bearing conditions are reasonable, the load distribution is even, and it possesses a certain degree of deformation resistance.

　　8)Standardized design facilitates simple production and design, with a shortened production cycle.

　　9)Beneficial for improving the interface structure between soft soil foundation structures and embankments.“Crosstai”Phenomenon, enhancing driving comfort and safety, and reducing post-construction operation and maintenance costs.

　　10)The steel corrugated pipe has excellent road performance, particularly in its low foundation requirements, ease of construction, rapid installation, and significant reduction in construction time, which outperforms conventional culverts. It will play a positive role in new and reconstructed highway projects, as well as in roadbed maintenance projects.
