First embodiment
As it is shown in figure 1, be the structural representation of the wavy metal lined with polyethylene steel pipe first embodiment of the present invention.The wavy metal lined with polyethylene steel pipe of the present embodiment, including corrugated steel tube body 1, the inner and outer wall of described corrugated steel tube body 1 is equipped with the polyethylene protective layer 9 being bonded as one with it.The thickness of polyethylene protective layer 9 is 0.1-10mm, concrete, and the thickness of the polyethylene protective layer 9 of the present embodiment is 1mm, and the thickness of polyethylene protective layer 9 sets according to actual operation requirements.
The wavy metal lined with polyethylene steel pipe of the present embodiment; by arranging polyethylene protective layer on the inner and outer wall of corrugated steel tube body; polyethylene protective layer has the characteristic of soft and tough, lighter than water, nontoxic and excellent dielectric properties; itself and corrugated steel tube body are bonded as one; wavy metal lined with polyethylene steel pipe is made to have the characteristic of corrosivity and insulation; and bearing capacity can be strengthened, it is possible to it is effectively increased service life.
Second embodiment
As it is shown on figure 3, be the structural representation of wavy metal lined with polyethylene steel pipe second embodiment of the present invention.The wavy metal lined with polyethylene steel pipe of the present embodiment, including corrugated steel tube body 1, the inner and outer wall of described corrugated steel tube body 1 is equipped with the polyethylene protective layer 9 being bonded as one with it.The thickness of polyethylene protective layer 9 is 0.1-10mm, concrete, and the thickness of the polyethylene protective layer 9 of the present embodiment is 1mm, and the thickness of polyethylene protective layer 9 sets according to actual operation requirements.
The corrugated steel tube body 1 of the corrugated steel tube body 1 of the present embodiment is provided with the ripple linear in wave, corrugated steel tube body 1 be respectively arranged at two ends with birdsmouth 2 and interface 3.The internal diameter of birdsmouth 2 is more than the external diameter of interface 3, and birdsmouth 2 is provided with undertaking ripple struction, and interface 3 is provided with the grafting ripple struction corresponding with accepting ripple struction.As shown in Figure 4, the structural representation after connecting for two corrugated steel tubes of the present embodiment.During use, interface 3 inserts in birdsmouth 2, the undertaking ripple struction of the present embodiment includes at least two and accepts crest 4, it is provided with undertaking trough 5 between adjacent two undertaking crests 4, grafting ripple struction includes at least two and accepts the grafting crest 6 that crest 4 is correspondingly arranged, and is provided with grafting trough 7 between adjacent two grafting crests 6.When interface 3 inserts after in birdsmouth 2, grafting crest 6 is corresponding with accepting crest 4, and grafting trough 7 is corresponding with accepting trough 5；The grafting crest 6 of interface 3 and accepting between crest 4 and being respectively equipped with sealing ring 8 between grafting trough 7 and the undertaking trough 5 of birdsmouth 2 of interface 3 of birdsmouth 2.
