Abstract
Auf einer Baustelle in einem Tunnel, in dem eine Gas-Pipeline montiert wurde, ereignete sich beim Absenken eines gerade geschweißten Rohrabschnittes mittels einer Seilwinde ein Seilriss. Dies führte zum Absturz der Rohrkomposition um mehr als 600 Meter und zum Tod von mehreren Arbeitern. Da die Bruchlast des Drahtseiles theoretisch bei weitem ausgereicht hätte, wurde eine detaillierte Schadenuntersuchung durchgeführt. Diese ergab, dass das Seil durch Gewaltbruch an einer Umlenkrolle gerissen war. Zum Seilriss haben eine hohe statische Zugbelastung des Seiles, zusätzliche dynamische Seilkräfte, hohe Zusatzbeanspruchung des Seiles an der Umlenkrolle, gestörter Seilaufbau und sicherheitstechnische Besonderheiten der verwendeten Seilwinde beigetragen.
Abstract
At a building site in the alps a gas-pipeline was being installed in a tunnel. When a section of the pipeline which had just been welded was lowered using a winch the wire rope snapped and the load dropped through the tunnel for more than 600 meters by which several workers were killed. Because the strength of the wire rope should theoretically have been sufficient a detailed failure analysis was carried out. The results of the analysis were that the rope had broken by overload at a guide sheave. The fracture had been promoted by a high static load of the rope, additional dynamic forces, high local stresses of the wires at the sheave, a disturbed composition of the strands in the rope and peculiarities of the used winch.
