The application of corrugated metal pipe (reinforcement) on high-filled roadbed has certain advantages. Because of its strong anti-deformation ability and anti-sedimentation ability, it has strong bearing capacity in soft soil, expansive soil and wet limit. The lower area is applied more and the effect is relatively better.
When the Corrugated metal culvert is used for the construction of the high fill roadbed, it can also effectively shorten the construction period; the steel bellows culvert is in the engineering cost, even if it is Where there is a shortage of flooring and labor, it is also less expensive than the similar economic span bridge culvert area
