Background technique

In house construction, it is generally necessary to arrange drains on the roof to divert the rain or accumulated water on the roof. There are generally two existing drainage methods, straight-draining and side-draining.

Straight drains refer to buildings with gutter on the roof. The drains are directly discharged from the gutter and enter the sink. However, due to the gutter, on the one hand, it affects the appearance, and on the other hand, the gutter itself is prone to siltation. , which needs to be cleaned from time to time.

On the other hand, the side-row type drain means that there is no gutter on the roof, but there is a parapet wall.
