<p>The collar pile is for mast piling, and has a shank consisting of profiled rods. Steel sheets (5-7) are fastened at distances to each other to the lower edge of the shank, with two neighbouring sheets being connected via bridging sheets (8,9). The steel sheets each carry a screen (14-16) for the outlet aperture of filling appliances (32-34) inserted from the tip of the shank into the screens. Trough-shaped steel sheets (2,3,4) are welded together to form the shank. The steel sheets are welded, so that their side edges project over the shank edges, with the bridging sheets being fastened to the projections. A stabiliser sheet (11,12) is located vertically on each bridging section.</p> |
