Problems solved by technology

[0002] At present, the plastic sewer pipes used in construction are widely used in the construction field due to their advantages of corrosion resistance, light weight, and good plasticity. With the popularization and application of this sewer pipe, new problems have attracted people's attention. People have come up with many solutions for the noise reduction problem of the downpipe, such as the patent ZL97210499.2: the downpipe with inner helical ribs, utilizes the inner side of the pipe wall to be provided with several helical ribs for diversion, which can make the water flow down when it flows down. , forming a swirl flow along the several helical ribs, thereby reducing the noise caused by the straight water flow, but the noise reduction effect is not very good; patent ZL99212628.2: Plastic pipe with internal helical ribs in the hollow wall , on the basis of the patent ZL97210499.2, the pipe wall of the sewer pipe is changed into a hollow form with reinforcement ribs. The hollow pipe wall with reinforcement ribs can not only enhance the strength of the sewer pipe, but also have the effect of sound absorption , better than the noise reduction effect of the patent ZL97210499.2, but it still cannot completely eliminate the noise caused by water impacting the pipe wall

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.

Abstract

The present invention relates to sewer pipe for building, and is especially silencing sewer pipe with soft inner layer. The silencing sewer pipe includes one outer layer of hard material and one inner layer of soft material, and the soft material can reduce the impact of water to pipe wall, reduce shock and silence. The silencing sewer pipe with soft inner layer may be used widely in buildings.

Description

technical field [0001] The invention relates to a construction pipe, in particular to a sewer pipe. Background technique [0002] At present, the plastic sewer pipes used in construction are widely used in the construction field due to their advantages of corrosion resistance, light weight, and good plasticity. With the popularization and application of this sewer pipe, new problems have attracted people's attention. In order to solve plastic People have come up with many solutions for the sound-absorbing problem of the downpipe, such as the patent ZL97210499.2: the downpipe with inner helical ribs, utilizes the inner side of the pipe wall to be provided with several helical ribs for diversion, which can make the water flow down when it flows down. , forming a swirl along the several helical ribs, thereby reducing the noise caused by the straight water flow, but the noise reduction effect is not very good; patent ZL99212628.2: plastic pipe with internal helical ribs in the h...
