Description
Technical field
The utility model belongs to pipe technology field, is a kind of sound insulation and noise reduction sewer pipe specifically.
Background technology
To live in the world of a sound, the sound on periphery is excessive just to turn into noise, and every household has aqueduct,
Draining sound in daily drainage pipe, is exactly one of noise source, noise make one vexed, meaning disorderly, it is anxious make an uproar, irritability, hearing damage,
The angiocarpy and nervous system of people is influenceed, especially middle and high layer building, when in the dead of night, dreamland of the people from sweetness
In wake up with a start, influence sleep, study and work etc., the injury brought is well-known.
The noise that drainage system is sent mainly is caused by 3 kinds of forms, and water impact tube wall draws respectively in drainage pipeline
Play current in noise, drainage pipeline caused by pipe vibration and cause noise and water caused by air Fast Compression in drainage pipeline
The sound of interior flowing.Therefore, when carrying out denoising pipe design, in addition to considering sound insulation, pipeline is reduced because impact shock institute
Caused noise is also the requisite measure of pipeline noise reduction.
Solve caused noise problem in drainage procedure at present, mainly take two approach：When start with from building structure,
Piping shaft or wall is set to cast by the way of secretly applying as foreign countries, the noise that this can fundamentally solve drainpipe is dirty
Dye problem, but due to traditional architectural design and matching operation, difficulty is bigger；Second, the structure by improving tubing
