The outer tube is provided with a plurality of groups of corrugated groups, and each group of corrugated groups is provided with a plurality of wave peak parts to form a group wave structure, so that the structural strength is improved, and the deformation resistance is strong. After the group wave structure is formed, sub-wave troughs are formed in addition to the main wave troughs, and the size of the sub-wave troughs is smaller than that of the main wave troughs, and the shapes of the sub-wave troughs are different. When the pipeline is buried, the shapes of the soil filled in the two wave trough parts are different, and the limiting degrees of the pipeline are different. The two wave trough parts can act synergistically to improve the stability of the buried pipeline together.
