Extending the Copenhagen Metro network constitutes part of the Danish capital’s City Ring. Towards this end, two tunnels – 1800 and 1600 m in length – are to be driven one after the other by mechanized means. Furthermore apart from the Nordhavn Metro stop a small tunnel will be driven towards the neighbouring tram line station.
Nothing on this February 8, 1960 indicated that things were soon about to change. The Economic Miracle’s ever growing stream of traffic congested the narrow cobblestone-lined roads of downtown...
Within the scope of the 2013 STUVA Conference, Mag. (FH) Susanne Fehleisen, ÖBB Infrastruktur AG, came out on top at the “Young Forum” competition winning the prize for her contribution “Koralm Tunnel: Applying the Rescue and Fire Protection Concept for complex Underground Construction Sites taking the Example of the Main Contract Section”. The prize involved a trip to Toronto to a rather unique tunnelling site.
At various construction sites the production accuracy regarding the axis deviations of diaphragm wall lamellae was investigated. After evaluating different series of measurements the normal distribution in accordance with Gauß was established as the suitable mathematical method for describing the frequency distribution. Under similar general conditions the determined parameters can provide the possibility for working out the anticipated axis deviations prior to executing a construction scheme.
The Panamanian transportation system has gone through several stages of transformation in the last three years. Government efforts focused on the construction of Line 1 of Panama City’s Metro, a project that took 20 months of implementation and came into operation at
the beginning of April 2014, covering a total distance of 14 km with almost 7 km running underground.
When a location in remote Northeastern Australia near the town of Moranbah was
designated as a new, “greenfield” site for a coal mine, the owner – the mining company Anglo American – was concerned about the project schedule and the necessary time to access the coal. A deep coal seam required access via decline tunnels within a quick time frame. To achieve this, the mine opted for the use of a tunnel boring machine, marking the first use of TBM technology in the Queensland coal industry.
The technical bulletin on tunnel coatings was created by updating the “Coatings for Tunnel Inner Shells” (2004) bulletin. The new European code of practice is lent particular consideration for...
The Deutsche Bahn AG is engaged in building the new and upgraded Berlin–Leipzig/Halle–Erfurt–Ebensfeld–Nuremberg rail route costing some 10 billion euros as Germany Unity Transport Project...
In Switzerland the Gotthard Base Tunnel is being built as part of the new rail routes crossing the Alps (NEAT). Towards this end, Siemens was commissioned to provide the tunnel control system. The technology in the Tunnel Control Centre (TCC) represents the beating heart for monitoring and controlling the electro-mechanical systems and is responsible for all operational processes. The electronic system caters for efficiency and safety in the tunnel. Thus the operator in the TCC receives a complete overview of the status of operational systems at any given time. In addition, the Maintenance Management Tool controls how maintenance operations are planned.
The Stuttgart–Ulm rail project with the new Wendlingen–Ulm route is numbered among the biggest development schemes for public rail transportation in Germany. Altogether 20 tunnels are being...
