초록 ▼

This invention is a box filter used in conjunction with newly constructed storm drains and the like to prevent undesirable amounts of sediment and other debris carrier by storm runoff from entering the storm drain. Upper and lower frames are provided with expanded metal interior and exterior sidewalls extending therebetween. The box-like structure has an open bottom, reinforcing plates adjacent the connection of a lift handle and corner braces to add rigidity to the system. An aggregate such as crushed stone is placed between the interior walls and exterior walls of the filter and act as a filter media for the sediment of the debris. This filter is reusable without loss of its filtering qualities due to its rugged construction and back flushable filter medium.

A regenerable filter means in combination with a storm drain, said filter means preventing undesirable amounts of sediment and other debris from entering said storm drain prior to paving of adjacent areas comprising: a frame means having peripheral wall means, an open bottom and an open top, said frame means including a pair of rectangular, upper and lower frame portions being vertically opposed in parallel, spaced apart relation, said upper and lower frame portions being fabricated from channel members, each of said channel members within said upper frame portion facing inwardly toward each of said channel members within said lower frame portion and being arranged to receive said peripheral wall means therebetween, said frame means further including corner braces interconnecting said upper and lower frame portions at the corner junctures thereof and being disposed in perpendicular relation thereto, said peripheral wall means including permeable, interior and exterior walls being permanently retained between said upper and lower frame portions and being arranged in parallel spaced-apart relation within said channel members defining a space therebetween; a crushed stone filter aggregate disposed in said space between said interior and exterior walls; and means for lifting said filter means for disposing the same on said storm drain whereby said filter means is positioned on top of an opening in said storm drain at the surface of an unpaved road enabling sediment and debris laden water flowing from said surface of said unpaved road to be filtered before entering said storm drain. The method of filtering sediment laden water on an unpaved road adjacent a newly constructed storm drain using a regenerable, filter means having an open bottom, an open top and spaced apart permeable interior and exterior walls containing a crushed stone filter aggregate disposed in space between said interior and exterior walls and means for lifting said filter means for disposing the same on a storm drain comprising: positioning said regenerable filter means on a storm drain at the surface of an unpaved road; introducing a flow of sediment laden water to the area adjacent said storm drain on the surface of said road; filtering said storm water through said permeable walls of said filter means; directing the filtered water through said open bottom of said filter means into said storm drain; removing said filter means from said storm drain when it has become saturated with sediment; flushing said filter means to remove the retained sediment; reclaiming the sediment collected by said filter means for further use; and repositioning said filter on said storm drain for continued use.
