AS 500^®

Straight web steel sheet piles are designed to form cylindrical structures, retaining a soil backfill and/or water.

The stability of constructions built up like that, a steel envelope and an internal soil mass, is guaranteed by their own weight.

Straight web sheet piles are mostly used on projects where rock layers are quite shallow (close to excavation level), where the excavation depth is very high, or where anchoring would be difficult or even impossible, or in seismic regions.

Main applications are:

• very deep cofferdams / dry-docks (temporary or permanent);
• deep-sea quay walls;
• breakwaters (maritime);
• dolphins to protect bridge pillars.

Straight web sheet pile structures are executed as circular cells or diaphragm walls depending on the site characteristics or the particular requirements of the project.

Straight web sheet pile structures are executed as circular cells or diaphragm walls depending on the site characteristics or the particular requirements of the project.

The forces developing in these sheet pile sections are essentially horizontal tensile forces requiring an interlock resistance corresponding to the horizontal force in the web of the pile. AS 500 interlocks comply with EN 10248, with interlock resistances R_k,s up to 6 000 kN/m. Note that both the resistance of the interlock and of the web need to be guaranteed. The safety factors applied to the web resistance and to the interlock resistance can be different.

All AS 500 straight web sections interlock with each other.
