ABSTRACT:
The method, operated in the manner of a production line involving fabrication of a plurality of modules, includes, as to each module, the steps of preparing a bed having the desired module shape and size; preparing a galvanized welded wire fabric or mesh; fitting said wire fabric along the floor and sidewall interior surfaces of the bed to begin building an infrastructure; installing and tying epoxy coated reinforcing bars, inserts, reinforcing plates, post-tensioning tubes and other reinforcing steel within said infrastructure; installing pre-stressing strand along floor and sidewall interior surfaces; applying tensile loading to the pre-stressing strands with a hydraulic jack and deadhead apparatus; pouring a layer of concrete on the floor of the bed; seating foam billets within billet receiving sections adjacent to the wire fabric and between the post-tensioning tubes; fitting wire fabric along said interior deck to build the remainder of the infrastructure; installing and tying epoxy coated reinforcing bars and other reinforcing steel within the interior deck portion of the infrastructure and connecting the same to the sidewall infrastructure; installing pre-stressing strand along the interior deck portion of the infrastructure; applying tensile loading to the interior deck pre-stressing strands with the hydraulic jack and deadhead apparatus; pouring cement mix into the bed around and over the foam billets; applying a smooth brush finish to the module; permitting the cement mix to cure; cutting the pre-stressing strand ends; and removing the module from the bed.
