Drainage channel installation device

A method of installing a drainage channel in a trench disposed between two supporting surfaces, said drainage channel including a pair of opposed side wall portions having substantially parallel opposed inner side wall surfaces that are spaced from one another by a width of the channel, said parallel side wall surfaces including installation device-engaging structures for releasably engaging an installation device, the method comprising:

• a) releasably securing opposed ends of at least one channel-securing member to said opposed inner side wall surfaces by means of said installation device-engaging structures such that the channel-securing member spans the entire width between the parallel side wall surfaces, said channel-securing member including a top surface, opposed side surfaces, and a cavity disposed in at least one of said side surfaces of the channel-securing member and extending through said top surface, a portion of said cavity distal from said top surface being wider than a portion of said cavity at said top surface;
• b) releasably securing a foot portion of a respective channel-hanging member to said cavity of at least one channel-securing member by fitting said foot portion into said cavity via said side surface in which said cavity is disposed, said channel-hanging member including a suspending unit for receiving and retaining a suspending member transversely of said opposed side wall portions of said drainage channel;
• c) disposing said suspending member in said suspending unit, said suspending member having opposed end portions and being of a length sufficient to span said trench;
• d) resting each said opposed end portion of said suspending member on a respective one of said supporting surfaces, whereby said drainage channel is suspended within said trench;
• and
• e) introducing into a region of the trench surrounding said drainage channel a fluid material capable of solidifying and maintaining said drainage channel in place in the trench.
