Pipeline for self-priming drainage and drainage pipe thereof

Abstract

The invention relates to the technical field of drainage, in particular to a pipeline for self-priming drainage and a drainage pipe thereof. The drainage pipe comprises a pipe body, water passing openings are formed in the two sides of the pipe body, and inclined first reinforcing ribs are arranged on the inner wall of the pipe body. On the other hand, the pipeline for self-priming drainage is provided, and the pipeline for self-priming drainage comprises the drainage pipe. The semicircular section of the pipe body enables the pipe body to have a good supporting effect, dust is not prone to being accumulated outside the pipe body, and flushing is convenient; the first reinforcing ribs in the pipe body are inclined and can play a supporting role in the axial direction and the radial direction of the pipe body at the same time, and use of materials is reduced; and in addition, the inclined reinforcing ribs prevent cross points from being generated between the first reinforcing ribs, andthe phenomena that due to the cross points of the reinforcing ribs, fluid flowing is hindered, impurities are accumulated, and microorganisms are bred can be avoided.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a pipeline for self-priming drainage and a drainage pipe thereof. Background technique [0002] The principle of self-priming is that in a certain closed space, the liquid at the highest point in the U-shaped tube moves to the lower nozzle under the action of gravity, and a negative pressure is generated inside the U-shaped tube, causing the liquid at the upper nozzle to be sucked into the highest point. Formation of water flow. Using the principle of self-priming, a drainage pipeline is installed at a higher position on the roof. The drainage pipeline is generally used for planting roofs or roofs that are prone to rainwater. The existing drainage pipelines are made of solid or cup-shaped convex surfaces on polymer sheets. The mouth of the cup-shaped protrusion is in the opposite direction of the protrusion, and the protrusion is generally upward, and the space between the prot...

Problems solved by technology

[0003] In the prior art, most of the drainage pipes are of trapezoidal structure, and reinforcing ribs are provided on the outside of the pipe wall, especially on the top, resulting in the accumulation of dust on the outer pipe wall of the drainage pipe, and it is not easy to wash; at the same time, due to the different places where the pipes are installed, it needs to be installed according to the needs of customers.
