Rainwater flow guiding pipe with silencing pipe walls and buffering canine-tooth-shaped protrusions on inner wall

Abstract

The invention provides a rainwater flow guiding pipe with silencing pipe walls and buffering canine-tooth-shaped protrusions on the inner wall. The portion between the two layers of pipe walls is divided into a plurality of closed small spaces which are filled with energy absorbing balls capable of eliminating noise. The canine-tooth-type staggered protrusions are arranged on the inner side of the 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 greatly decreased, sound generated when the rainwater impacts the pipe walls is also greatly reduced, and the effect of eliminating noise is achieved; the height of the protrusions becomes smaller accordingly, there is a large enough space in the flow guiding pipe on the premise that it is guaranteed that noise is lowered, and the utilizing rate is increased; wavy protrusions are arranged on the upper surfaces of the protrusion at the uppermost ends, the water flow speed can be further decreased during rainwater washing, and the effect of further eliminating noise is achieved; the outer surfaces of the protrusions are wrapped in PVC membranes, during rainwater washing, water flow can be buffered, 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 pipe wall noise reduction and inner wall canine protuberances 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 wall ...

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.
