24、8-1999 1 Scope This standard specifies requirements, recommendations and information concerning the execution of permanent or temporary sheet pile wall structures in accordance with 2.4 of ENV 1991-1:1994 and the handling of equipment and materials. It does not give requirements and recommendations

25、for the installation of specific parts of the structure such as ground anchorages and piles which are covered by other codes. It applies only to steel sheet pile walls, combined walls and wooden sheet pile walls. Composite structures such as Berliner walls and sheet pile walls in combination with sh
