The work involved the execution of a waterproof bottom slab with Jet-grouting columns, along the future track path situated between diaphragm walls performed for the excavation. Once the columns were tested, we proceeded to design the required distribution and type sections.

Jet Grouting
Madrid Metro (Spain) TBM Excavation
Jet Grouting

The soil improvement treatment executed by Jet grouting type I, was carried out to avoid possible terrain settling brought about by the TBM ground excavation during the execution of the metro tunnel. For that reason, Jet grouting columns with inverted V shape, were deployed in almost the whole surface to be treated, the only modification applied being the inclination of the columns.
