Drainage pipeline with noise reduction function
The invention discloses a drainage pipeline with the noise reduction function. The whole drainage pipeline is arranged in a broken line shape and comprises at least two main pipes and pipe connecting pieces connected with two adjacent main pipes end to end respectively. The pipe connecting pieces are of bend structures. Spiral ribs are arranged in the pipe connecting pieces or/and the main pipes and are consistent in rotation direction. The structure is simple, installation is convenient, blowdown liquid flow forms rotational flow in the pipeline and flows along the wall of the broken line pipeline to an underground drainage pipeline, and noise pollution caused by the fact that the liquid flow freely falls is avoided. The spiral ribs are arranged on the pipe walls in the main pipes and the pipe connecting pieces of the bend structures, rotational flow is accelerated through the spiral ribs, the water flow spirally flows down along the pipe walls in the drainage process, and the good noise reduction effect is achieved; and meanwhile, sticky accumulated objects on the wall of the pipeline can be better taken away through the rotational flow liquid, the pipeline has the self-cleaning function and is not prone to blockage, and maintenance cost is reduced.
