Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 7, the HDPE reinforced double-wall corrugated pipe of this embodiment includes a pipe body 1 and a ring portion 2, wherein the ring portion 2 is disposed around the outer surface of the pipe body 1, and the cross section of the ring portion is trapezoidal in this embodiment. The ring-shaped part 2 comprises a steel strip 21, an HDPE layer 22 and an adhesive layer 23, the steel strip 21 comprises a top part 211 and an extension part 212, and the extension part 212 is arranged at two ends of the top part 211. The HDPE layer 22 is connected with the steel belt 21 through a bonding layer 23, the HDPE layer 22 is arranged on the outer surface of the steel belt 21, and the reinforcing part 3 is arranged in the annular groove 24 between the adjacent annular parts 2. Both sides of the reinforcing part 3 are connected with the annular part 2, a plurality of reinforcing parts 3 are arranged in the annular groove 2, and the plurality of reinforcing parts 3 are arranged at intervals. In the above-described embodiment, the structural strength of the annular portion 2 can be enhanced by providing the steel band 21 in the annular portion 2. By providing the extension 212, the steel strip 21 can be compressed in the HDPE layer. Through set up rib 3 in ring channel 24, can strengthen ring channel 2's structural strength, when avoiding its atress to buckle, can avoid the recess expansion to excessively lead to the fracture when buckling, can resist and buckle, also can resume the shape fast after buckling. In this embodiment, the adhesive layer 23 is adhesive resin.
