Abstract

A multi-sided portable trench and pit form system having at least two panels forming each side, each panel releasably interconnectable along the vertical margins of each adjacent panel and side. Elongated rigid braces are also provided which releasably interconnect to and against the sides and spanning the interconnected panels to rigidize the sides. Additionally, the elongated braces also interconnect at their ends to rigidize the preselected relative angular positioning of the sides one to another. The entire assembly forms a barrier or perimeter wall as required within which a user may safely function when working below ground level. An opening may be provided in one panel or between adjacent panels forming a side and having a slideable closure panel to provide working access outside of the enclosure. This modular system is adaptable to variation in the number of sides required, as well as variation in both side width and height.
