1.- «Reinforcing soil in front of the toe of a diaphragm wall with jet-grouting.»

Autores: J. Sánchez Martín

Keywords: Diaphragm wall, excavation, anchor, blue marls, jet-grouting, improving soil strength

Resumen: This paper shows a case in which superjet grouting has been used to improve soil strength
and passive earth pressure at the toe of a diaphragm wall. This treatment had made it possible to excavate deeper than planned, i.e., from -14.00m to -17.35m, in order to enlarge the car park of a building in Seville from four to six floors, when the diaphragm walls were already constructed.
