Temporary silt guard for storm water collection basin inlet

Claim 2

A temporary silt guard for enclosing an open end of a drop inlet, said silt guard comprising: a body having a lower end constructed to seat upon the open end of the inlet, a spaced upper end, and a series of openings formed intermediate said upper and lower ends to enable runoff water to pass through said body; means for filtering silt placed about and supported by said body for filtering silt and debris from water passing therethrough and into the inlet to enable runoff water to be drained from a site with silt and debris within the water prevented from passing into and collecting within the inlet; and a top portion extending upwardly from said body for covering and restricting access to the open end of the drop inlet, said top portion having an upper end an opening, defined therein.

Claim 3

The temporary silt of claim 1 and wherein said means for filtering comprises a silt screen material.

Claim 4

The temporary silt guard of claim 1 and wherein said body further includes a series of spaced slats defining said openings in said body and supporting said means for filtering.

Claim 5

The temporary silt guard of claim 1 and wherein said body tapers from said lower end toward said upper end to enable stacking of additional silt guards thereon.

Claim 6

The temporary silt guard of claim 1 and further including a cover mounted to said upper end for covering said opening.

Claim 7

The temporary silt guard of claim 5 and further including a means for locking said cover over said opening.

Claim 8

A silt guard for use with an upstanding drop inlet, the drop inlet having an open upper end with a tapered upper portion surrounded by an upper rim, said silt guard comprising: an elongate body portion formed about a longitudinal axis, said body portion having a first end and a spaced second end; a spaced series of openings defined in said body portion intermediate said first end and said second end to enable water to pass through said body; a silt screen material placed about the exterior periphery of said body portion are passed over each of the openings of said spaced series of openings defined in said body portion for filtering silt from water passing through said body portion.

Claim 9

A silt guard for use with an upstanding drop inlet, the drop inlet having an open upper end with a tapered upper portion surrounded by an upper rim, said silt guard comprising: an elongate body portion formed about a longitudinal axis, said body portion having a first end and a spaced second end; a spaced series of openings defined in said body portion intermediate said first end and said second end to enable water to pass through said body; a silt screen material placed about the exterior periphery of said body portion are passed over each of the openings of said spaced series of openings defined in said body portion for filtering silt from water passing through said body portion.

Claim 10

The silt guard of claim 7, further comprising a bottom rim formed at the first end of said body portion for being received on the open upper end of the drop inlet.

Claim 11

The silt guard of claim 8, wherein said bottom rim comprises a flange for being seated on the upper rim of the drop inlet.

Claim 12

The silt guard of claim 7, further comprising an elongate top portion formed at the second end of said body portion, said top portion having a radially spaced series of openings defined therein.

Claim 13

The silt guard of claim 10, said top portion defining an opening therein, said top portion including a lid sized and shaped to be received on said opening for enclosing the second end of said body portion thereby.

Claim 14

The silt guard of claim 11, further comprising a locking device constructed and arranged to lock said lid on said opening.

Claim 15

The silt guard of claim 10, said top portion extending from the second end of said body portion along said axis and being tapered inwardly toward said axis.

Claim 16

The silt guard of claim 7, said silt screen being fastened to said body portion at the second end thereof by a radially spaced series of fasteners.

Claim 17

The silt guard of claim 7, wherein said body portion includes a radially spaced series of elongate slats extending from the first end of said body portion to the second end thereof about said axis, said slats defining said spaced series of openings in said body portion therebetween.

Claim 18

A silt guard for use with an upstanding drop inlet, the drop inlet having an open upper end with an upper rim, said silt guard comprising: an elongate body portion formed about a longitudinal axis, said having a first end and a spaced second end; a bottom rim at the first end of said body portion for being received on the upper rim of the drop inlet; an elongate top portion formed at the second end of said body portion, said top portion extending from the second end of said body portion along said axis and being tapered inwardly toward axis; a filter box portion formed within said body portion intermediate said first end and said second end thereof, said filter box including a radially spaced series of openings defined in said body portion to enable runoff water to drain through said body portion; and a silt screen material fastened to the exterior periphery of said body portion about said filter box, said silt fence being passed over each of said spaced series of openings for filtering silt and debris from runoff water draining through said body portion to prevent such silt from passing into and collecting within the drop inlet.

Claim 19

A silt guard for use with an upstanding drop inlet, the drop inlet having an open upper end with an upper rim, said silt guard comprising: an elongate body portion formed about a longitudinal axis, said having a first end and a spaced second end; a bottom rim at the first end of said body portion for being received on the upper rim of the drop inlet; an elongate top portion formed at the second end of said body portion, said top portion extending from the second end of said body portion along said axis and being tapered inwardly toward axis; a filter box portion formed within said body portion intermediate said first end and said second end thereof, said filter box including a radially spaced series of openings defined in said body portion to enable runoff water to drain through said body portion; and a silt screen material fastened to the exterior periphery of said body portion about said filter box, said silt fence being passed over each of said spaced series of openings for filtering silt and debris from runoff water draining through said body portion to prevent such silt from passing into and collecting within the drop inlet.

Claim 20

The silt guard of claim 16, wherein said silt screen material is fastened to said body portion at the second end thereof and is draped over said bottom rim for extending about and over at least a portion of the open upper end of the drop inlet.
