GERMANY'S FIRST ELEMENT WALL INSTALLED IN STUTTGART

This structure is temporary work safeguarding tunnel construction in open excavation, proceeding at the open centre of palace square where a major underground railway station is under construction. This report describes the step by step excavation methods adopted down to eight successive working levels at a batter of 10 degrees the mounting of the 1.5M by 1.5M by 0.2M precast concrete elements, the drilling of boreholes, and the installation of ground anchors inserted as required to lengths of 10-20M. A 50mm thick mesh-reinforced Gunite concrete lining was ussed to seal the exposed face during excavation, and a Gunite rim, close fitting and tapered to a maximum thickness of 100mm was used to seal the wall elements in place. Wall deflections, ground settlements, anchor forces and ground pressure distribution are being continuously monitored. /TRRL/
