Rainwater flow guiding pipe with inner wall noise elimination function

Abstract

The invention discloses a rainwater flow guiding pipe with the inner wall noise elimination function. The portion between two layers of pipe walls is divided into a plurality of small closed spaces. Noise generated when the pipe walls are washed by rainwater can be preliminarily blocked; in addition, the small spaces are filled with energy absorption balls; when sound is transmitted into the small spaces, energy of sound wave vibration is absorbed, and noise is further eliminated; fang-type staggered protrusions are arranged on the inner side of the inner pipe wall in the radial direction. After downward rainwater wash is performed, rainwater flows along a convolution-shaped path formed by the staggered protrusions, the rainwater wash speed is greatly decreased, the pipe wall impacting sound is greatly lowered, and the effect of eliminating noise is achieved; the upper surfaces of the protrusions are provided with wave-shaped protrusions, during rainwater washing, the water flow speed can be further decreased, the outer side of the outer pipe wall is coated with noise elimination cotton, and the effect of eliminating noise is further achieved.

Description

technical field [0001] The invention belongs to the technical field of waterproofing of modular houses, and in particular relates to a rainwater diversion pipe with an inner wall sound-absorbing function. Background technique [0002] With the rapid development of society in recent years and the improvement of people's living standards, architecture is also quietly changing. [0003] People's requirements for architecture are not only to provide a place to live, but also to pay more attention to the overall structural performance of the house. Modular building is the mainstream of building development, and it is more and more favored by people because of its superior performance. [0004] The direction of building modularization is to use designed building components to be manufactured in a factory environment, and then transported to the construction site for installation. It generally includes a steel structure frame and modular wall panels, and the wall panels are forme...

Problems solved by technology

In the house roofing project, it will involve roof waterproofing and roof waterproofing, especially for modular houses. Because the building materials abandon the traditional brick and tile structure, the walls and roofs built with multi-layer materials are more prone to water leakage.
