ABSTRACT:
A support device for lining a ditch which is supported by braces. The support device has an inner plate and an outer plate parallel to and facing the inner plate. A frame is provided which has an upper cross bar, a lower cross bar and side bars placed between and in contact with the plates at their periphery. The side bars include brace connection means for releasably engaging the braces. Longitudinally extending trapezoidal-shaped webs are provided on each plate. The webs each have two sides and a top which is parallel to each plate. The distance between adjacent webs along each plate is approximately equal to the width of the top. The webs on the inner plate are offset from the webs on the outer plate so that the webs on the plates matingly interconnect. The tops are in contact with the facing sheet plate and the sides of adjacent webs are parallel and in contact with each other. Reinforcement pipes extend from the upper cross bar through the sides of the webs to the lower cross bar in a direction perpendicular to the longitudinal direction of the webs.
