Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is described in further detail. It should be understood, however, that these embodiments are provided so that this disclosure will be thorough and complete, and that many of the details set forth in this specification will be sufficient to provide a thorough understanding of one or more aspects of the present invention, even though these aspects of the invention may be practiced without these specific details.

Example 1

As shown in fig. 1, 2 and 3, in this embodiment, a PE water supply pipe includes an outer pipe 1, a buffer layer 2 and an inner pipe 3, wherein two side edges of the outer pipe 1 are provided with longitudinal corrugated folds 4, a cross section of the outer pipe 1 is in an oval shape with folds on two sides, the inner pipe 3 is a circular pipe sleeved inside the outer pipe 1, the buffer layer 2 fills a gap between the outer pipe 1 and the inner pipe 3, a joint part 5 is further provided at an end of the whole water supply pipe, the joint part 5 is a bellows flared part, an outer side of the joint part 5 is in a decagon structure, and a thread is provided inside the joint part 5.

The thickness of the outer layer pipe 1 is 1-3 times of that of the inner pipe layer, the nearest distance between the outer pipe layer 1 and the inner pipe layer 3 is 0.3-1cm, so that the extrusion of the coating on the appearance layer when the pipeline is deeply buried reduces the acting force on the inner layer pipe through the buffering of the buffer layer, and the damage condition is reduced.
