Detailed Description
To facilitate understanding of the structure of the present invention, the following description is made with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of an embodiment of the compensation type toughening double-wall corrugated pipe shown in the present invention, fig. 2 is a side view of the compensation type toughening double-wall corrugated pipe shown in the present invention, and fig. 3 is a side view of the compensation type toughening double-wall corrugated pipe shown in the present invention showing a included angle a. As shown in fig. 1 to 3, the utility model provides a compensation type toughening double-wall corrugated pipe, including: a cylindrical smooth inner tube 10, a corrugated outer tube 20 disposed outside the inner tube 10, and a parting line 30 disposed on the corrugated outer tube.
The corrugated outer tube 20 includes peak sections 21 and valley sections 22 alternately arranged in the axial direction. The wave crest section 21 comprises a circular ring-shaped pipe wall 211 and a wave crest support assembly 212, wherein the circular ring-shaped pipe wall 211 is integrally arranged, the wave crest support assembly 212 is arranged at the bottom of the circumference of the circular ring-shaped pipe wall 211 and is used for filling earthwork backfilling dead angles, the wave crest support assembly 212 comprises two wave crest supports 2121 which are symmetrically arranged on two opposite sides of a radial vertical plane of a horizontal tangent plane of the circular ring-shaped pipe wall 211, the bottom surface of each wave crest support 2121 is flush and level and is arranged in the horizontal tangent plane, and the side surface of each wave crest support 2121 connected with the bottom.
