10 A lignite opencast mine becomes a paradise for water tourists The largest artificial lake district in Europe is being developed at Lausitz in Brandenburg Tourism instead of lignite: The largest artificially created 'lake district' in Europe is currently being created in Brandenburg. This "Lausitz Lakeland" will be fashioned over the next twenty years by flooding redundant open-cast mines, and which will eventually lead to an area of 13,000 hectares of water. The heart of the Lausitz Lakeland will be the chain of lakes between Senftenberg and Hoyerswerda. This chain of lakes with its 5,500 hectares of water will arise from the connection of new lakes with navigable canals. The area is to be developed as a regional attraction, providing a water environment with an active and sporty character. Attractions such as bathing beaches, yacht marinas, water-skiing, jet- skiing and floating houses are planned. One highlight will be a seaplane port on the north shore of Lake Sedlitz. Lake Sedlitz is found in the Oderspreewald- Lausitz district directly on the border with Saxony. One of the lakes in this watery landscape is Lake Sedlitz, one of project's largest lakes, which is connected by canal with Lake Ilse in Brandenburg and Lake Geierswald (Sorno canal) and Lake Partwitz (Rosendorf canal). The chain of lakes flows out into the Schwarze Elster. A great challenge for ThyssenKrupp GfT Bautechnik was the connection of the pit lakes Sedlitz, Skado and Koschen by channels to be navigable at a later date for ships. It was planned to use a LARSSEN 22 double pile (length 9 metres, total; weight 244 tonnes) to excavate the two 1,000-square metre trenches. Statics analysis, geological survey, ramming plan and other documents did, however, lead ThyssenKrupp experts to two better alternatives, from which the customer "Tief- und Wasserbau Boblitz" choose the LARSSEN 703 DB. The larger system width, when compared with the LARSSEN 22, gives significant benefits in handling and placement, which in turn saved time and expense. In spite of adverse weather conditions it was possible to meet the building schedule. For pile driving, the customer had rented a ZR 28 telescopic excavator with an MRZV 600 V vibrator. Following just two days of introductory training by our service engineer, the clients were able to proceed with the ramming work unsupervised. Once again, ThyssenKrupp GfT Bautechnik was able to prove itself as an expert system provider by preparing the structural and ramming plan, delivering the sheet piling and hiring the pile driving technology. � Data and facts Commissioning company: LMBV Lausitzer und Mittelbrandenburgische Bergbau- Verwaltungsgesellschaft mbH, Senftenberg Engineering Project supervision / Construction management: BHM Boeschen - Haeber -Muschter Partner Ingenieurgesellschaft, Juedenberg General contractor: TWB Tief- und Wasserbau GmbH, Luebbenau Sheet pile sections: LARSSEN 703 DB, length 9.00 m Pile driving technology: ZR 28 telescopic excavator with a MRZV 600 V vibrator Completion: Beginning of 2006 Additional information: Mathias Himmel, Berlin branch Telephone: +49 (0) 3375 9217-24 E-Mail: mathias.himmel@thyssenkrupp.com Just the water is missing: one day, the worked out pits of the opencast mine will be flooded.
Ready for the next generation of container vessels Three new berths are being developed at the Predoehlkai in the Hamburg harbour An ever increasing number of permanently growing container ships with a draught of up to 16.5 metres dominate the image of international trade across the world's oceans. It is the ports and logistic companies dotted along the North Sea coast that are currently experiencing a logistical and economic race. Only container terminals with sufficient depth of water can still be called at. This situation demands that a further three moorings are added to the current four berths available at Predoehl quay. A particular challenge ThyssenKrupp provides the sheet piles for berth 2, currently the largest quay wall construction site, at Hamburg harbour. Joint general contractors Ed. Zueblin AG and Per Aarsleff A/S secured the order from the property developer HPA (Hamburg Port Authority). At a total length of 390 metres and a harbour floor depth of -16.70m msl (mean sea level), the new berth 2 will make handling of large container vessels of the next generation possible. The new quay wall to be constructed parallel to the existing one is a deep foundation onsite-mixed concrete slab. The elevation change of +5.85 m mls to -16.70 m mls will be lined with combined steel sheet pile consisting of DB PSp 1006 as king piles and PZi 675-11.5 as intermediate piles and secured at the back by hinged anchors. Three in situ concrete piles were used for the deep foundation of the slab. New impetus: container transhipment in the Hamburg harbour is constantly increasing. A further challenge is the actual nature of the soil layers, which dictated piling to a greater depth through to the stable gravel and sand layers up to the high-strength micaceous clay layer. This necessitated the evacuation of a ramming trench in order to remove the upper layers of gravel debris. The trench was subsequently refilled and the DB PSp 1006 King piles were placed in position from a raised platform and driven to the final depth by ramming. Before the intermediate piles PZi 675-11.5 could be fitted, drilling had to be carried out to loosen the ground between the beam piles. To ensure that the interlocks did not declutch during pile driving, signal transmitters were also used. 28 metre long PSt 400/119 steel columns with a welded DB HOESCH 3606 anchoring base were used to anchor the quay wall. These hinged anchors were connected to the King piles with round bolts, lowered to the harbour floor and positioned and stabilized by the anchor base. After this it was possible to start backfilling the berth with sand. From the new berth level, the 51 cm diameter in situ concrete piles, the DB L 703K as flood protection apron and bearing piles for the shore side crane track could be driven in. � Data and facts: Property Developer: Hamburg Port Authority (HPA), Hamburg General contractor: Ed.
