摘要

The prefabricated drainage system for the balcony of the apartment house according to the present invention is installed on the balcony of the apartment house to collect the water flowing into the balcony, and the drainage path is selectively changed according to the amount of water flowing into the balcony and collected so that the water can be drained. water collection housing to be made; a main drain pipe formed in a vertical direction in the water collecting housing, a drain inlet formed on the bottom surface of the balcony, and a groove having a swirl structure formed on an inner circumferential surface to drain water flowing into the water collecting housing; and the inlet of the sub drain pipe through which water is drained is formed above the inlet of the main drain pipe, so that the drainage of water flowing into the balcony through the main drain pipe is insufficient, so that the water level reaches the position where the drain inlet of the sub drain pipe is formed. Drains water flowing into the balcony through the main drain pipe, including a sub drain pipe of a swirl structure that sub-drains the water that has reached the drain inlet of the sub drain pipe, and is in proportion to the amount of water flowing into the balcony to the sub drain pipe By controlling the amount of water being drained, it has the effect of allowing water to drain smoothly without overflowing the balcony.
