Water supply and drainage pipeline for high-rise building

Abstract

The water supply and drainage pipeline for the high-rise building comprises an outer pipe and an inner pipe arranged in the outer pipe, guide strips are arranged on the inner wall of the inner pipe, and a concave area is formed between every two adjacent guide strips which are spirally distributed; the guiding strips and the adjacent sunken areas jointly guide water flow to flow downwards in the spiral direction on the inner wall of the inner pipe, and the buffering device is arranged between the inner wall of the outer pipe and the outer wall of the inner pipe and used for buffering impact of the water flow in the inner pipe. According to the water supply and drainage pipeline for the high-rise building, the pipeline is designed to be of an inner and outer double-layer structure, a buffer structure is designed between the double-layer structure, and a corresponding cleaning mechanism is arranged in the inner wall of the inner-layer structure, so that the inner wall of the pipeline can be cleaned by filling water or air; and meanwhile, an original concave area can become a new spiral guide structure through a corresponding expansion mode of a corresponding cleaning structure, and meanwhile, the surface can be cleaned.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage of high-rise buildings, in particular to a water supply and drainage pipeline for high-rise buildings. Background technique [0002] When the drainage pipeline is actually used, it is necessary to consider the various effects of the flow of water on the pipeline, especially when it is used in high-rise buildings, it is necessary to consider the noise generated during the drainage process and the impact of water hammer on the pipeline when the water flow is large. In the prior art, in view of pipeline noise, in addition to wrapping sound insulation cotton on the outside of the pipeline, corresponding multi-strand convex spirally distributed guide strips are also arranged on the inner wall of the pipeline, so that the water can be guided spirally downward accordingly when it falls. flow, thereby reducing noise, but the existing similar pipes still have the following problems in act...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of water supply and drainage pipe for high-rise buildings to solve the problem that in most cases mentioned in the background art, the amount of sewage discharged in a single time in the building is relatively small. On the inner wall of the pipeline with a raised guide structure, a large amount of dirt is likely to accumulate in the concave area (that is, the side of the raised part). This type of dirt has strong adhesion and cannot be washed out directly through subsequent sewage discharge. After gradually accumulating, it is easy to cause The spiral strip loses its role of guiding and reducing noise, and it is very troublesome to clean the inner wall of the pipe in high-rise buildings
