CONSTRUCTION OF THE DAALSE TUNNEL IN UTRECHT

BAU DES DAALSETUNNELS IN UTRECHT

THE 60 M LONG AND 50 M WIDE TUNNEL WAS BUILT TO PASS A ROAD BELOW THE RAILS OF THE MAIN RAILWAY STATION. AS THE RAILWAY TRAFFIC WAS NOT ABLE TO BE INTERRUPTED AND THE LEVEL OF WATER IN THE GROUND WAS FAIRLY HIGH, THE HEIGHT OF THE STRUCTURE HAD TO BE KEPT TO A MINIMUM, 210 DRIVEN PILES, EACH ABOUT 12 LONG, WERE CONSTRUCTED FOR THE FOUNDATION OF THE BASE OF THE TUNNEL; SUPPORTING BANKS WERE CONCRETED ON TO THESE, AND EXTENDED ON BOTH SIDES BEYOND THE RAILWAY LINES TO FORM A SLIDING PATH FOR THE CONSTRUCTION AND LAUNCHING OF THE TOP STRUTS OF THE TUNNEL. THE TOP OF THE TUNNEL IS A SLAB 0.90 M THICK AND 60 M WIDE. THE OVERBURDEN WAS NOT DISTURBED DURING THE LAUNCHING OF THE ROOF OF THE TUNNEL.
