Abstract

PROBLEM TO BE SOLVED: To facilitate attachment/detachment of a trap and prevent the contraflow and malodor of sewage water by mounting a trap in a fittingly fixable state to a branch pipe socket part in a catch basin, and mounting a cover, closable by a means such as a hinge, on the opening of the trap. SOLUTION: A cleaning opening is provided at the upper end of a catch basin body 1, and a main pipe socket part 4 and a branch pipe socket part 3 are provided at the opposed side faces of the bottom part of the body 1. A branch pipe side opening part 6 of a U-shape trap 5 is insert-fitted to the inner peripheral surface of the branch pipe socket part 4. A recessed groove is formed at the outer peripheral surface of the connecting opening part 6 of the U-shape trap 5, and watertightness is held by an O-ring 7 fitted into the recessed groove. A cover is mounted on the opening part of the U-shape trap 5, and the cover is closably fitted so as to be easily opened/closed by the water pressure of sewage flowing down into the U-shape trap 5 through a branch pipe. Attachment/detachment of the U-shape trap is therefore facilitated, and the contraflow and malodor of sewage water can be prevented.
