Abstract

A trench forming assembly for forming a trench of predetermined shaped is disclosed according to the present invention. The assembly includes a pair of parallel elongate frame members for defining a support surface for supporting a trench cover. The assembly also includes an elongate form body for shaping a hardenable trench forming composition into the predetermined shape of the trench and having opposed side surfaces with which the frame members may be engaged. The trench forming assembly further includes at least one pair of upwardly extending legs for anchoring the frame members in a predetermined location. Each upwardly extending leg is joined at a top portion to one of the frame members and is joined at a lower portion to a corresponding leg for forming a generally U-shaped structure. The generally U-shaped anchoring leg structure maintains engagement of the frame members with the side surfaces of the form body. Once the trench is formed, the frame members may be removed, if desired, from the top portions of the upwardly extending legs to expose a pair of grate receiving recesses.
