AS 500 Cell geometries
The geometry of the structure is quite complex to determine. Below is an extract of the catalogue of basic geometries for the standard angle of 35° for AS 500 junction piles used for circular cells.
Please refer to our brochure “AS 500® Straight web steel sheet pile – design & execution manual” for further details.
Do not hesitate to contact us for optimizing the layout: if the dimensions of the a straight wall built with circular cells are a little bit flexible, then you might need only two different junction piles, which simplifies the task of the workers at the job-site.
