<p>The present invention relates to a surface drain system comprising of, a plurality of channel unit in functionally operative configuration for collecting and/or discharging water, in which the channel units is characterized with a tongue on the inner wall of the channel unit such that the said tongue provides adaptable means of fitting together cover/grating unit and channel unit by locking with tie-rod, a plurality of cover/grating unit to receive incoming water, being placed atop to securely aligning channel units forming a structure, a plurality of connecting units, at least a pair of end caps adapted to fit on either end of channel and cover/grating units, a plurality of drain outlets mounted on surface of channel unit in functionally operative configuration adapted to discharge channel unit content. The channel units of the present invention are advantageous as they have adequate load bearing capacity and can function independently without any additional support of filling agents. Additionally these channel units have flexibility of the placement of cover/gratings with no predetermined positions.</p> |
