Examples
specific Embodiment approach 1
[0007] Specific implementation mode one: see figure 1 , figure 2 , the shock absorption and noise reduction sewer pipe with soft inner layer of the present embodiment is made up of hard layer pipe wall 1 and soft layer pipe wall 2, and hard layer pipe wall 1 is made of hard material, and soft layer The pipe wall 2 is made of soft material, and the soft layer pipe wall 2 is fixed on the inner side of the hard layer pipe wall 1 .
specific Embodiment approach 2
[0008] Specific implementation mode two: see image 3 , Figure 4 The shock-absorbing and noise-absorbing sewer pipe with a soft inner layer in this embodiment also includes several helical ribs 3, and the several helical ribs 3 are made of hard materials, which are fixed on the hard layer pipe wall 1 and Between the soft layer pipe walls 2, the hard layer pipe walls 1 are integrated.
[0009] Several helical ribs 3 added in this embodiment play the role of diversion and noise reduction.
specific Embodiment approach 3
[0010] Specific implementation mode three: see Figure 5 , Figure 6 The difference between the shock-absorbing and noise-absorbing sewer pipe with a soft inner layer in this embodiment and the second embodiment is that the several helical ribs 3 are made of soft materials, which are fixed on the inner wall of the soft layer pipe wall 2 On, and become one with the soft layer tube wall 2.
[0011] The difference between this embodiment and the second embodiment is that the several helical ribs 3 are made of soft material, which has a better shock absorption effect and a better noise reduction effect.
