Claims

[Scope of utility model registration request]

A drainage hole is formed outside the bent part of the main body of the drain pipe which is bent into a substantially L-shape, and a water level adjustment hole is formed above the water fall hole, and within the upper opening of the main body of the drain pipe. A plurality of annular protrusions forming guide grooves communicating in the vertical direction are formed on the wall surface, and a communication hole that can communicate with the drainage hole and the downstream side of the drain pipe main body is formed in the lower part of the interior of the main body of the drain pipe. A falling water regulating valve is provided, and the upper part of the main body of the drain pipe has a through hole that can communicate with the water level adjusting hole and a protrusion that can be engaged with the annular protrusion, and can be freely engaged with and detached from the falling water regulating valve. 1. A water level and flow rate regulating device, characterized in that water level regulating valves formed in the main body and penetrating at least downwardly are rotatably disposed so as to be in close contact with the main body of the drain pipe.
