Specific embodiment
The utility model is further described with reference to specific embodiments and the drawings.
Embodiment one
As shown in Figures 4 to 6, the double-colored helical bellows of a kind of double-deck ribbing, including by banding sheet material spiral winding and phase
The tube body formed is mutually bonded, the inboard wall of tube body is equipped with one layer of internal layer 5 different from tube body color, which is plastic cement internal layer,
Its color is tangerine color or yellow.The plastic cement internal layer is compounded in inboard wall of tube body by the way of extrusion molding.The plastic cement internal layer
Inner wall smooth is smooth, not only contributes to passing through for sewage, is not easy to accumulate dirt, and mask the bonding between banding sheet material
