Abstract
Abstract A drainage system includes a conduit connector which is integrally molded within a precast drainage system component in order to provide for the interconnection of a variety of drainage system components, such as drainage channel sections and catch basins. The conduit connector can include a connector body which defines an aperture of a predetermined shape and size which are selected to match and snugly engage the conduit. The connector body further includes at least one locking anchor to secure the connector body against movement relative to the precast component. The locking anchor can include a longitudinal movement resisting anchor and/or a rotational movement resisting anchor. In order to further secure the conduit connector within the precast component, the wall of the precast component is substantially continuous about the conduit connector. In addition, the connector body preferably has a predetermined thickness which is no greater than the thickness of the precast component walls. Accordingly, the conduit connector will not protrude outwardly beyond the precast component, thereby enabling the precast component to be readily transported and stored without incurring significant risk of breakage due to inadvertent contact of the conduit connector with another object.
