摘要: Flumes for manhole inverts are described and formed of integrally molded segments which interfit with each other so as to connect inlets an outlet a independent the shape size manhole. The flumes made in set one pipe segment either is connected open channel or thereto suitable fasteners overall length flume being substantially less than distance between inlet Another has only generally smaller have both segment. provided end flanges enable their connection similarly shaped form inverts.
