AI Technical Summary
In sponge cities, vortex is likely to occur when the water flow in the vertical drainage pipeline is too large, resulting in the inability to discharge rainwater in time and reduce drainage efficiency.
A seepage and drainage mechanism including drainage pipe, side drainage parts and flow guides is designed. The side drainage parts are equipped with a horizontal drainage port at the bottom of the drainage pipe, and a flow guide curved surface inside the flow guides to guide the vertically falling water body. Flow to the horizontal drain to avoid vortex formation.
The water body is directed to the horizontal drain through the flow guide, effectively avoiding the vortex when the water body falls in the vertical pipeline and improving the drainage efficiency.
