Rainwater flow guiding pipe with silencing pipe wall and silencing outer pipe wall

Abstract

The invention provides a rainwater flow guiding pipe with a silencing pipe wall and a silencing outer pipe wall. The portion between the two layers of pipe walls is divided into a plurality of closed small spaces which can primarily obstruct noise generated when the pipe walls are washed by rainwater. Beside, the small spaces are filled with energy absorbing balls. When sound is transmitted into the small spaces, sound wave vibration energy is absorbed, and noise is further eliminated. Canine-tooth-type staggered protrusions are arranged on the inner side of inner pipe wall in the radial direction. After rainwater is washed down, the rainwater flows along a circumflex-shaped path formed by the staggered protrusions, rainwater washing speed is decreased, sound generated when the rainwater impacts the pipe walls is reduced, and the effect of eliminating noise is achieved. The height of the protrusions becomes smaller while the rainwater flow speed is decreased, and the situation that the rainwater overflows from the upper end of the flow guiding pipe when the water flow is too large is also prevented at the same time on the premise that it is guaranteed that noise is lowered. The outer side of the outer pipe wall is wrapped by silencing 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 sound-absorbing pipe walls and outer walls. 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 f...

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.
