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...
The Kö-Arch Tunnel in Düsseldorf is the first tunnel in Germany to be completely illuminated by LED technology. The tunnel is part of the complex “Kö-Arch” urban construction concept, which diverts traffic in the city centre underground in favour of green areas and pedestrian routes. The entire tunnelling project at Düsseldorf’s Kö-Arch is due to be completed by the end of 2015.
