Sound insulation and noise reduction drainage pipe

Abstract

The invention discloses a sound insulation and noise reduction drainage pipe. The sound insulation and noise reduction drainage pipe is characterized by comprising drainage pipe bodies and a water pipe connecting piece, wherein the water pipe connecting piece is used for connecting and fixing the two drainage pipe bodies, each drainage pipe body comprises an outer-layer pipe body, a sound insulation pipe and an inner-layer pipe body which are sequentially arranged from outside to inside, the water pipe connecting piece comprises a fixing bearing device and a pressing device installed on the fixing bearing device, the fixing bearing device comprises a fixing plate, a supporting plate is parallel to the fixing plate, a positioning column matched with a positioning cylinder is fixed to the lower surface of the supporting plate, the positioning column is inserted into the positioning cylinder, the pressing device comprises two thread rods, the thread rods are installed on a connection barrel in a penetrating mode through second installation holes, and gears, first arc plates and second arc plates are fixed to the surfaces of the two thread rods correspondingly. By means of dual improvement for the drainage pipe bodies and the water pipe connecting piece, the drainage pipe has the excellent sound insulation and noise reduction effect.

Description

technical field [0001] The invention belongs to the technical field of building drainage pipes, and in particular relates to a sound-insulating and noise-reducing drainage pipe. Background technique [0002] Noise and vibration are important factors affecting the health of human settlements. With the advancement of science and technology and the emphasis on the elements of human settlement health, more and more attention has been paid to the improvement of architectural acoustic environment by the society and users. 3A high-demand housing, Green buildings, healthy residences, and ecological buildings all put forward index control requirements for the architectural acoustic environment, but in the implementation process, there is still a lack of corresponding technical support for the design and construction of the architectural acoustic environment. [0003] The noise emitted by the drainage pipes used in buildings is mainly caused by three forms, namely, the noise caused by...
