Abstract
A storm sewer inlet grate is provided, which is temporary and removable, to keep trash and debris and eroded soil out of a storm sewer. There are two parts: a rectangular box made of steel re-bars and steel mesh, and surrounding mesh bags filled with gravel and made of wire mesh. The device is placed in a gutter parallel to and against the street curb opening of the storm sewer drain. The mesh bags are easily removable one by one.
Claims20
A street storm sewer inlet grate system comprising:
- (a) a box structure substantially open on its inside and sized and shaped to be placed against, and covering, a storm sewer inlet,
- (b) mesh or rods covering some or all of the surfaces of the box, and
- (c) a plurality of mesh bags, separate from each other and from the box structure and not connected to each other or the box structure, and individually capable of being placed on, and removed from, the street surface, each individual bag containing gravel or other lumps of solid dense material, placed against each other, and around the box, on the surface of the street from one side of the storm sewer inlet to the other,
- whereby the storm sewer inlet is substantially covered by the box structure, whereby the mesh bags form a continuous barrier on the surface of the street around the box from one side of the storm sewer inlet to the other, and whereby trash and eroded soil are prevented from being washed by water or blown by air into the storm sewer inlet, and whereby because of their weight, the bags strongly resist movement out of position by the force of flowing water.
A method of preventing trash and eroded soil from being washed by water or blown by air into a storm sewer inlet in a street or gutter of a street, comprising the steps of:
- (a) placing a box structure substantially open on its inside and having mesh or rods covering some or all of the surfaces of the box against, and covering, the storm sewer inlet in a street or gutter, and
- (b) placing, on the surface of the street, a plurality of mesh bags, separate from each other and from the box structure and not connected to each other or the box structure, and individually capable of being placed on, and removed from the street surface, each individual bag containing gravel or other lumps of solid dense material, against each other from the street or gutter area at one end of the storm sewer inlet, around the box structure, and to the gutter or street area at the other end of the storm sewer inlet,
- whereby the bags form a continuous barrier, on the surface of the street, around the box from one end of the storm sewer inlet to the other, and whereby eroded soil and trash are substantially prevented from being washed by water or blown by a air into the storm sewer inlet, and whereby because of their weight, the bags strongly resist movement out of position by the force of flowing water.
