Die neue DIN 4093 regelt wichtige Punkte zu Entwurf und Bemessung von verfestigten Bodenkörpern, die durch Düsenstrahl‐, Deep‐Mixing‐ oder Injektions‐Verfahren hergestellt werden. Anders als in der alten Injektionsnorm werden Themen der Ausführung, die europäisch einheitlich behandelt werden, hierin nicht erfasst. Der vorliegende Beitrag erläutert wichtige Regelungen dieser vollständig neu erstellten Norm sowie einige Besonderheiten, die vor der Anwendung der genannten Verfahren zu beachten sind.
Comment on the new DIN 4093 – Design of strengthened soil
The new DIN 4093 contains important rules for the design of strengthened soil installed by jet grouting, soil mixing or grouting. Unlike in the old German grouting standard code, aspects of execution, which are content of European standards, are no longer included. This publication explains essential requirements and recommendations of this completely new standard code as well as some particularities which have to be obeyed prior to the application of the named technologies.
