Modular and componential trench drain system

A forming system for in-ground formation of a trench drain for removing water from a surface comprising at least one channel, a plurality of grate frames, a plurality of support anchors integrally attached to said grate frames and a grating, said trench drain system being adapted to be supported in-ground by a supporting material formed beneath and outwardly about said drain system in conformity thereto, wherein:

• said channel being a generally V-shaped component comprising a bottom wall integrally connected to a pair of opposing, spaced apart sidewalls, thus forming a trough and a top opening opposite said bottom wall, said bottom wall and sidewalls defining a fluid carrying space and said top opening defining a fluid entrance, said sidewalls terminating in generally horizontal flanges extending outwardly from and perpendicular to said sidewalls directly above and resting on said supporting material;
• each of said grate frames being a generally L-shaped component with a bottom horizontal surface of the L being secured to the upper surface of one said flange and the side vertical surface of the L disposed relatively outwardly from said fluid carrying space;
• said support anchors being integrally attached to the outside neutral surfaces of the L;
• said grating being placed on and support by the interior L surfaces of said grate frame for covering said top opening;
• and
• said grating being formed of a relatively strong material sufficient for support of above-ground loads on the surface against entrance into the trough, said channel being formed of a relatively lightweight thin-walled resin material for ease of handling but generally incapable of load-bearing support of said grating and above-ground loads placed thereon, said outwardly-extending disposition of said flanges locating said grate frames above the supporting material for load bearing support of said grating and loads placed thereon substantially entirely by the supporting material.

• said channel being a generally V-shaped component comprising a bottom wall integrally connected to a pair of opposing, spaced apart sidewalls, thus forming a trough, and a top opening opposite said bottom wall, said bottom wall and sidewalls defining a fluid carrying space and said top opening defining a fluid entrance, said sidewalls terminating in generally horizontal flanges extending outwardly from and perpendicular to said sidewalls directly above and resting on said supporting material;
• and
• each of said frame members having a horizontal portion secured to the upper surface of one said flange;
• said support anchors being integrally attached to said horizontal portion for securement to the supporting material;
• said channel being formed of a relatively lightweight thin-walled resin material for ease of handling but generally incapable of load-bearing support of above-ground loads placed on said frame members, said outwardly-extending disposition of said flanges locating said frame members above the supporting material for load bearing support of loads placed thereon substantially entirely by the supporting material.
