Abstract

PURPOSE: To reduce cost of drainage pipe installation by making use of vacant space formed at upper portion of cross-section of a branch pipe as a ventiliation space, so as to eliminate the provision of conventional ventilation pipes. To this end, the brnach pipe has a vertically elongated cross-sectional shape, e.g. oval, gourdshape, egg-shape or a polygonal shape, so that the vacant space may effectively beformed.
