Straight web sheet piles are designed to form cylindrical structures, generally closed, retaining a soil backfill. In general, they are used where the piles are liable to be subjected to tensile forces, hence interlocking strength is of prime importance. They include cellular cell structures (cofferdams) and diaphragm cell structures. It is mostly used on projects where rock layers are close to ground level, where the excavation depth removes toe support, or where anchoring cannot be reasonably provided.
Applications of Straight Web Sheet Piles
