Drainpipe noise test system and test method for high-rise/ultra-high-rise building

Abstract

The invention proposes a drainpipe noise test system and test method for a high-rise / ultra-high-rise building. The system includes a high-rise / ultra-high-rise residence experiment tower, and a water supply and drainage system and a water circulation system, which are installed in the high-rise / ultra-high-rise residence experiment tower. The high-rise / ultra-high-rise residence experiment tower includes a water drainage layer and a test layer which is arranged below the water drainage layer and spaced with the water drainage layer for at least ten layers. A sound source chamber and a receiving chamber are arranged in the test layer. Each of the sound source chamber and the receiving chamber is provided with a sound test device. The invention proposes the drainpipe noise test system for the high-rise / ultra-high-rise building and a test method thereof for the first time so that a basis and a reference method are provided to pipe noise test of a high-rise / ultra-high-rise water drainage system and thus noise reduction research and test for high-rise / ultra-high-rise water drainage pipes are facilitated and disturbing on lives of residents, caused by pipe noises, are reduced so that the comfort degree of a residential environment is improved.

Description

technical field [0001] The invention relates to the technical field of building drainage noise detection, in particular to a high-rise / super high-rise building drainage pipe noise testing system and testing method. Background technique [0002] Building drainage system noise is one of the most important sources of construction noise, which directly affects people's normal life and work. According to the provisions of the national standard GBJ118-88 "Code for Design of Sound Insulation of Civil Buildings": the noise in the bedroom at night shall not exceed 30dB, and the maximum shall not exceed 40dB. However, in the actual test, the noise generated by a considerable part of the drainage pipeline system is far greater than 40dB. In engineering examples, there is also no lack of disturbance of residents' sleep and annoying effects due to the noise generated by the drainage pipeline system, as well as neurasthenia and other non-specific diseases caused by it.

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic drainage noise test is based on the "Building Drainage System Noise Test Method" (CJ / T 312-2009), the measurement arrangement is similar to the European standard, and the measurement arrangement is from the center of the drain to the bottom of the riser The distance between the centers of the horizontal pipes is only 5.8~7.5 m, that is, the height of 2~3 floors, which is far from the actual situation of drainage in high-rise / super high-rise residential buildings.
