NEW AUSTRIAN TUNNELING METHOD

THIS METHOD IS DESIGNED FOR WORKING IN GROUND WHICH CANNOT BE WORKED UNSUPPORTED WHEN APPLYING THE TRADITIONAL TUNNELING TECHNIQUES. IT HAS BEEN USED SUCCESSFULLY IN EUROPE FOR JOBS INCLUDING RAPID TRANSIT SYSTEM TUNNELS IN FRANKFORT AND NUREMBERG. THE IDEA IS TO PREVENT PRESSURE BUILD UP. AS QUICKLY AS A NEW SURFACE IS EXPOSED, IT IS COVERED WITH SHOTCRETE SO THAT THE SOIL ITSELF BECOMES THE SUPPORTING MATERIAL. WHERE NECESSARY THIS INITIAL SHOTCRETE LINING CAN BE REINFORCED. AS SOON AS THE FULL TUNNEL SECTION IS OPENED, THE OUTER LINING IS CLOSED BY A CONCRETE INVERT ARCH WHICH FORMS A FULL RING. SAVINGS RESULT IN THAT COSTLY TEMPORARY SUPPORTS, HEAVY TUNNEL ARCHES, AND LININGS USED IN TRADITIONAL TUNNELING METHODS ARE ELIMINATED.
