Abstract
A silt barrier includes a main frame (10) which is disposed horizontally over a catch basin which is to have silt blocked therefrom, the main frame (10) has end frames (24, 25) rotatable from a stored flat position into a vertical working position. A pair of wooden frames (26, 27, 30, 31) are lodged between the end frames (24, 25) and porous plastic silt barrier sheeting (48) is stapled (50-55) to the wooden frames, surrounding the entire structure. The silt barrier is clamped to the catch basin (41, 70) with j-bolts (38, 39).
Claims15
A silt barrier subassembly for preventing silt from entering the mouth of a catch basin of the type having a generally horizontally disposed grating covering the mouth of the catch basin, comprising:
- a pair of side rails joined at their ends by end rails forming a generally rectangular, hollow main frame;
- a pair of end frame members rotatively disposed to said main frame in a manner to permit rotation from a folded position, in which the end frame members lie adjacent to said main frame, and an extended position in which said end frame members extend upwardly from said end rails generally perpendicular to said main frame;
- and
- means disposed on said main frame having a portion extending downwardly below said main frame movably with respect to said main frame and adapted to engage a portion of the grating of the catch basin for drawing said main frame downward toward the grating to secure said main frame tightly to said catch basin above said grating.
A silt barrier subassembly for preventing silt from entering the mouth of a catch basin of the type having a generally horizontally disposed grating covering the mouth of the catch basin, comprising:
- a pair of steel side rails joined at their ends by steel end rails forming a generally rectangular, hollow main frame;
- a pair of end frame members disposed on said main frame in a manner to permit movement from a non-use position, in which the end frame members do not extend outwardly of said main frame, to a use position in which said end frame members extend upward from said end rails generally perpendicular to said main frame;
- and
- means disposed on said main frame having a portion extending downwardly below said main frame movably with respect to said main frame and adapted to engage a portion of the grating of the catch basin for drawing said main frame downward toward the grating to secure said main frame tightly to said catch basin above said grating.
A method of blocking silt from entering the mouth of a catch basin having a generally horizontal grating across the mouth thereof, comprising:
- establishing a frame having vertical portions extending upwardly from a horizontal, generally hollow main frame portion that is of a size and shape slightly larger than the mouth of the catch basin;
- surrounding said vertical portions with porous plastic silt barrier sheeting;
- securing said sheeting to said frame;
- positioning said frame, with said sheeting secured thereto, above the grating of the catch basin with the mouth of the catch basin totally within said frame;
- and
- securing said frame tightly to said grating, whereby silt flowing toward the catch basin is blocked by said sheeting secured to said frame before reaching the mouth of the catch basin.
