Heavyweight Steel Sheet Piling are produced by Shoreline steel in SZ-222 SZ-24. A ladder, stairway, or ramp shall be provided at all personnel points of access where there is a break in elevation of 19” or greater. Ladders, stairways and landings shall have unobstructed access at the top and base and be free of debris. Prefabricated modular walls consist of walls as described in SZ-222. Additionally this type wall may consist of precast reinforced concrete elements which are placed or stacked to form a series of SZ-24 shaped modules along the length of the wall with the top of the “T” forming the face of the wall.
Heavy cold formed sheet pile SZ-25 SZ-27 are supplied by Piling and equipment. Incipient failure of a masonry block unit (MBU) wall. • MBU walls cost 40% less than an equivalent section reinforced concrete wall, but with a 75% reduction in moment capacity.This type wall is similar to a crib wall except each cell is three sided and open at the back at the pressure surface used for external stability analysis. Manufactured ladders must be rated for extra heavy-duty work. Contractors shall provide ladders which are safe and in accordance with all applicable codes and SZ-25 standards. If the wall is retrained by deadman anchors or tiebacks, a reversal of the skin friction acting against the back of the wall can suddenly increase the lateral load by 30%, and failure can be triggered by excessive strain on the anchor bar or cable. Prefabricated modular SZ-27 wall dimensions needed for external designs for a battered three-tier wall.
