ABSTRACT:
A method and apparatus for forming a trench or catch basin void with removable cardboard components that fold up to create a three dimensional trench void form, and pair of elongated frame members to define a support surface for a trench cover is disclosed according to the present invention. The removable cardboard form includes a rectangular shape with outwardly extending edges running longitudinally along the top surface. A pair of elongated frame members lay in a coplanar, spaced relationship to the side and bottom of the outward extended top edges of the predetermined form. The frames are used to define a surface to support the trench covers. A pair of U shaped support legs are joined at the ends to the frame members with nuts in order to maintain clearance for total encasement and adjust the top of the form to the desired finish elevation. Another preferred embodiment utilizes a rectangular rail for creating a drain support in a finished catch basin.
