Flat Web Sections

Straight web sheet piles are designed to form cylindrical structures, generally closed, retaining a soil backfill.

The stability of the construction is guaranteed by its own weight from the steel envelope and an internal soil massive.
Straight web sheet piles are predominantly used un projects where rock layers are close to ground level, where excavation depth is critical or where anchoring would be difficult or 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 sheets are primarily the horizontal traction forces requiring interlocks especially designed for declutching resistance, corresponding to the horizontal force in the web of the pile.

Note: all the straight web sections interlock with each other.
Interlock strength of up to 5 500 kN/m can be guaranteed.
