Pipe walls and rainwater guide pipe with outer wall eliminating noise and inner wall conducting buffering

Abstract

The invention discloses pipe walls and a rainwater guide pipe with the outer wall eliminating noise and the inner wall conducting buffering. The part between the double layers of pipe walls is divided into a plurality of small airtight spaces so that noise generated when the pipe walls are washed through rainwater can be preliminarily prevented. In addition, the small spaces are filled with energy absorbing balls, when sounds are transmitted into the small spaces, energy of wave vibration is absorbed, and noise is further eliminated. Protrusions which are arranged in a dog-tooth-shaped staggered manner are arranged on the inner side of the inner pipe wall in the radial direction, rainwater flows along a convolution-shaped path along the staggered protrusions after washing down, the washing speed and the sound of impacting on the pipe walls of the rainwater are reduced, and the function of eliminating noise is achieved. The height of the protrusions is also reduced along with reducing of the flow speed of water flow, and under the premise of noise reduction, rainwater can be prevented from flowing out of the upper end of the guide pipe when water flow is too large. Wavy protrusions are arranged on the upper surfaces of the protrusions, the outer side of the outer pipe wall is wrapped with noise eliminating cotton, and therefore noise can be eliminated further.

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 a pipe wall and an outer wall for noise reduction and an inner wall for buffering. 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...
