12 Tour de France A 28 autoroute widened between Tours and Le Mans The LARSSEN 430 sheet pile section was used in autoroute construction in France. In France, the A 28 autoroute between Le Mans and Tours is currently being widened. A particular challenge facing the construction experts involved crossing two valleys near to the townships of Choiselle and Nais. The ground conditions, especially the rock bed which functions as a support for the base, favoured constructing the abutments with sheet pile walls. ThyssenKrupp GfT Bautechnik supplied about 1,200 tonnes of LARSSEN 430 sheet piles in pile lengths of 13.5 to 17.0 metres to France. The sheet piles were supplied as double piles and initially placed using vibrators onto the lime marl stratum. The sheet piles were then positioned into the rocky bed using a diesel pile driver (D25). This guaranteed that the vertical loads arising from the carriageway plate were diverted into the foundation soil. So as to achieve a secure fixing in the rocky soil, the experts from ThyssenKrupp GfT Bautechnik decided on sheet piles of S 355 GP, a superior steel quality. The use of a pile-driving system with rollers made it possible to observe exactly the specified axial dimensions. LARSSEN 43 single piles could be used to form the transition between abutment and wing wall, making it possible to dispense with expensive welded corner constructions. Since the LARSSEN 430 sheet pile section has a high moment of inertia and section modulus, the abutment and wing walls could be produced without anchors. The French company LEDUC, which undertook the construction work, thus used an ideal sheet pile section for economic reasons. In addition, dispensing with tying meant that it was possible to achieve a shorter construction time. � Data and facts Client: Cofiroute, Sèvres Constructor: SCAO,Nanterre, driving work: LEDUC,Vernon Planning: Fougerolle et Compagnie BIEP Contact person: Marc Gartier de Saint Louis, Conseiller technique 25, Rue Saint Pierre, 57000 Metz, Phone: +33 (0)148 08 67 69, E-Mail: marc.gratier@wanadoo.fr
The future will have a new name: CT 4 Bremerhaven: new container terminal for Euro 498 million The most important port construction project in Bremerhaven this decade is the extension of the river quay. After Container Terminal IIIa has been completed in autumn 2003, the future of Bremerhaven will have a new name: CT 4. But it is clear that the transhipment of standardized containers will roughly double in the coming ten years. Unless the terminal is expanded and unless there are four new berths for large container ships, Bremerhaven will have exhausted its capacities by 2006. More jobs Now that the planning approval procedure has been completed, construction is to begin this year. The construction work should be finished by the end of 2007. Bremenports, the principal for this largescale project, estimates that the work will cost about Euro 498 million. This investment for the future is being financed from the earnings of the “special port assets”, to which the government of the Federal State will have to allocate a total of Euro 672 million over the next 43 years. The new CT 4 Terminal will create about 10,000 new workplaces until 2020. ThyssenKrupp GfT Bautechnik has now been awarded the contract for the extension work on the container quay in Bremerhaven by the working group commissioned by the Federal Land of Bremen. The contract has a sales volume of approx. Euro 30 million. “We are pleased at the confidence which is being placed in us. Additional workplaces are being secured and created by the construction The port area of Weddewarden to be enlarged. After completion of CT 4 the container quay in Bremerhaven exceeds to a length of 5.2 km. and supply work in the area of Bremerhaven as well as in Peine and Dortmund”, says a spokesman of the ThyssenKrupp group. The extension work will begin in the middle of this year, creating in Bremerhaven the largest continuous container quay in the world. The facility at the mouth of the River Weser will be extended by about 1.7 kilometres. Salzgitter AG in Peine, in which the Federal State of Lower Saxony has a stakeholding, will produce for the large-scale order in Bremerhaven approx. 40,000 tonnes of sheet piles and steel beams, which will be supplied by ThyssenKrupp GfT Bautechnik. After the extension has been completed, the container quay in Bremerhaven will be about 5.2 kilometres long. � 13
