ABSTRACT:
A method and means of improved construction of concrete culverts in which reinforcement bars are supported by removable racks until the bottom of the culvert is poured and interior wall forms are mounted on wheels with side wall forms pivoting with respect to the top wall form. By this combination of features, a very rapid setting of reinforcement bars and wall forms may be accomplished, and rapid removal of re-bar supports and the interior forms may be effected.
