Problems solved by technology

[0004] Its inner tube, intermediate tube and outer tube are all made of co-polypropylene material. After co-extrusion molding, each layer will be tightly connected, and the noise between each layer will be reduced only through the difference in the material of the intermediate tube. The effect is has limitations

Abstract

The invention discloses a split type crack-resistant sound insulation drain pipe. The pipe comprises pipe bodies, at least two layers of pipe bodies are arranged from inside to outside, and a gap is formed between each two adjacent layers of structures. According to the technical scheme, a double-layer or multi-layer structure is adopted, the gap is formed between each two adjacent layers of structures, and each two adjacent layers of structures from a split type structure through the gap, so that when the outer layer of structure is impacted and ruptured, impact force can be dispersed throughthe layered structural characteristic of the multi-layer structure, the inner layer of structure is protected, and the overall structural strength is improved; meanwhile, the gap between each two adjacent layers of structures can form a cavity in the sound transmission process, so that the sound insulation effect is improved; each two adjacent layers of structures are limited and fixed through convex structures or concave structures of the outer wall of the inner layer of structure, so that the strength of a connecting structure between the two adjacent layers of structures is enhanced; and meanwhile, a plurality of refracting faces are formed through a special-shaped structure, so that the sound transmission effect is further reduced.

Description

technical field [0001] The invention belongs to the field of drainage pipes, in particular to a split-type crack-resistant silent drainage pipe. Background technique [0002] The current silent drainage pipes mostly use composite structures, that is, multiple pipe bodies are used to socket each other, and the middle pipe body is made of special materials to achieve sound insulation effects; [0003] For example, the patent document of application number CN201120277654.0 discloses a drainage pipe, especially a silent drainage pipe. The utility model provides a quiet drainage pipe which is easy to produce, comprising an inner pipe, an intermediate pipe and an outer pipe, and the intermediate pipe is made of sound-absorbing and noise-reducing materials. The silent drainage pipe is divided into three layers, the inner layer is in contact with the fluid, the middle layer is sound-proof, and the outer layer is protected. This not only makes the pipe have a sound insulation effect...
