ABSTRACT:
A trench-box panel (200, 202) comprises an array of horizontal elongate "C-section" members (210) one on top of another and welded together at w continuously along their lengths. The members (210) are longitudinally staggered to leave spaces (234) between the ends of alternate members (210) at each side edge (200C, 202C) of the panel (200, 202). Robust vertical angle-members (236) and flat members (238) are welded to the ends of the horizontal members (210) to seal the ends of cavities (220) inside the horizontal members (210).
