Abstract
Abstract Debris removing screen basket and overflow apparatus embodiments for use in a storm collection sewer. The device has two embodiments, each including a central panel with foldable wings in each side of the central panel. During initial assembly, the wings are folded up around the central panel for insertion through a manhole cover. Each wing can have an optional extension panel that slidable attached to each wing by bolts/screws and nuts through longitudinal slots. In the first embodiment, the wings, extension panels and the central panel form a single type panel that is inclined at a variable angle so as to suit various floor conditions at a particular location. In the first embodiment the panel and wings have a front edge that sits on the inlet drain floor and a top edge touching an upper ridge of the basket. The inclined variable angle can be between approximately 35 and 75 degrees but preferably at approximately 52 degrees, with the top edges leaning in the direction of the outlet pipe from the storm collection sewer. Both wings and and extension panels have angled deflector top portions while the central panel does not have a deflection portion. A screen mesh basket is supported behind the central panel by hooks. Storm water and debris entering the street grate area fill up the area in front of the wings, extension panels and central panel. The rising water when reaching the height of the deflector portions is forced over the top ridge of the central panel and into the basket. In the second embodiment the central panel and the wings form a ramp chute which angle down from street level into the basket itself. In the second embodiment, overflowing water can run around the sides of the filled basket. Filled baskets in both embodiments are removable by a single worker while the remaining structure is left undisturbed.
