Compared with reinforced concrete pipe culvert, steel corrugated pipe
has the following advantages:
1. Easy to maintain, just need to do the inner wall protection.
2. The steel corrugated pipe has obvious economic benefits in Shouting frozen soil area and soft soil subgrade area.
3. The steel corrugated culvert pipe has been embalmed, the life times is about 80-100years.
4. It has good integrity and plasticity, which is suitable for complex road sections with strong deformation resistance.
5. It’s good thermal conductivity, which is slight influence to substructure of cryolithozone.
6. The steel corrugated culvert pipe is manufactured by factory, which is not affected by the environment and is conducive to the quality control.
7. Assembling construction, short construction period, light weight and convenient installation, reduce large amount of labor in high altitude area, and can be constructed in winter.
