It is more suitable than reinforced concrete cover culverts for cold area projects such as the China-Nepal Highway. At present, the application of Guanhan in the permafrost area is still in the primary trial use state, and more experience needs to be accumulated on the manufacturing, transportation and construction techniques of Guanhan. In addition, due to the characteristics of the corrugated pipe itself, excessive settlement can easily cause diseases such as water retention, pipe joint deformation, and joint fracture. Therefore, long-term observations are needed for the application of corrugated Guanha
