Abstract
Abstract A refuse collecting frame for a drainage sewer, particularly a frame placed beneath a cover of a sewer drainage opening to accumulate refuse and permit easy disposal of refuse accumulated therein in order to prevent blockage of the sewer. The refuse collecting frame includes a frame body and a refuse collecting basin. The frame body is preferably a rectangular or cubic frame structure having a dimension corresponding to the opening of the sewer drain. A filtering net or a porous board with a plurality of penetrating holes is incorporated at each lateral side and bottom of the frame. A plurality of right-angled hangers are formed at spaced positions along the upper edges of an open upper side of the frame for firmly hanging the frame on a sewer opening by positioning the right-angled hangers on a stepped portion formed along edges of the sewer opening beneath a separate cover. A hole of appropriate size is formed at the middle of the filtering net or the porous board at the bottom of the frame body for placing of the collecting basin with a peripheral edge of the basin being supported about the circumference of the hole.
