Securing foundation pits for south faces of the Mrázovka tunnel


Securing foundation pits for south faces of the Mrázovka tunnel

South-east and south-west faces of the Mrázovka tunnel are situated in deep side-hill cuts that were stabilised by microrider walls anchored at several levels by permanent and temporary strand anchors. The side-hill cut was dewatered by drains, stabilised on the surface and protected by sprayed concrete reinforced with welded nets. Jet-grouting was used to interconnect individual sections and hill-side levels.
