Downcomer silence structure

Technical Field

The application relates to the field of sewer pipe construction, in particular to a silencing structure for a sewer pipe.

Background

Sewer pipe noise is generally formed by low frequency noise caused by the impact of sewer pipe on pipe wall and high frequency noise of large water flow during flushing. The source of sewer pipe noise is the vibration caused by water flow impacting the pipe walls. The sound is amplified by repeated refraction within the tube. The greater the displacement and flow rate, the thinner the pipe wall, the greater the noise and the enhanced by resonance.

At present, in the building process, sewer pipes are generally arranged in corners of toilets or staircases in a centralized mode, and because fewer people stay in the toilets or the staircases, the influence of noise generated when the sewer pipes drain water on people is reduced.

In view of the above-mentioned related technologies, the inventor believes that in some residential buildings of users, since the rooms in the buildings are small, even if the sewer is installed in a narrow space such as a toilet, the noise generated by the sewer can still propagate into the rooms through the walls, and further normal office work and rest of the residents in the rooms are affected.
