fig. 2 is a schematic cross-sectional view of a first riser according to an embodiment of the present invention.
Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Referring to fig. 1, a spiral-flow type dual-riser drainage system according to an embodiment of the present invention includes a first riser 10 and a second riser 20, which are disposed in parallel, wherein the first riser 10 is used for drainage, the second riser 20 is used for exhaust, the first riser 10 and the second riser 20 are communicated with each other through a communication pipe 30, and gas in the first riser 10 flows into the second riser 20 through the communication pipe 30 and is discharged.
Specifically, as shown in fig. 2, the first vertical pipe 10 is a reinforced internal spiral drainage pipe, a plurality of spiral ribs 11 are disposed in the first vertical pipe, and the communication pipe 30 is disposed obliquely upward from the first vertical pipe 10 to the horizontal direction of the second vertical pipe 20 to prevent water in the first vertical pipe 10 from overflowing into the second vertical pipe 20. The angle of the communication pipe with the horizontal direction from the first riser to the second riser is 10 ° to 45 °, and in the present embodiment, 30 ° is described as an example. Through the arrangement of the spiral ribs 11, the nappe phenomenon can be effectively eliminated, the water flow speed of the vertical pipe is reduced, the hydraulic working condition of the vertical pipe is improved, the pressure fluctuation and the water flow noise of the water flow of the vertical pipe are reduced, and therefore the drainage capacity of the vertical pipe is greatly increased. The communication pipe 30 is disposed obliquely upward, and thus, water in the first riser pipe is prevented from flowing into the second riser pipe, thereby affecting the air discharge performance of the second riser pipe.
In addition, a plurality of stoppers 31 facing the first vertical pipe are arranged inside the communication pipe 30, and the stoppers 31 are spirally distributed in the communication pipe 30 to provide a gas circulation channel and improve the exhaust efficiency.
