Straight web sheet piles are designed to form cylindrical structures, generally closed, retaining a soil backfill. The stability of constructions built up like that is guaranteed by the weight of the internal soil massive. Straight Web sheet piles are mostly used on projects where rock layers are close to ground level, where the excavation depth is very important or where anchoring would be difficult or even impossible.
Straight web sheet pile structures are realised as circular cells or diaphragm walls depending on the site characteristics or the particular requirements of the project.
The efforts developing in these sheet pile sections are essentially horizontal traction forces requiring interlocks especially designed for declutching resistance, corresponding to the horizontal force in the web of pile.

*One side, excluding inside of interlocks
Note: all straight web sections interlock with each other.
Interlock strenghts up to 5 500 kN/m are possible.
