Description

This document specifies requirements, recommendations and information concerning the execution of permanent or temporary sheet pile wall, combined pile walls, high modulus wall structures and the handling of equipment and materials. This document does not give requirements and recommendations for the installation of specific parts of the structure such as ground anchorages, displacement piles and micropiles which are covered by other documents. This document is applicable to steel sheet pile walls, combined walls, high modulus walls, and synthetic sheet pile walls (composite), precast concrete and timber sheet pile walls. Tubular piles included in combined walls and high modulus walls can be filled with concrete. Composite structures such as Berliner walls and sheet pile walls in combination with shotcrete, are not covered by this document.
