Building a fast track between Germany and Denmark

Fehmarn带固定链接计划沉浸tunnel proposed to connect Germany and Denmark, allowing travellers to go by train between countries in only seven to 10 minutes or drive through a four-lane motorway. Upon completion, this18公里长的隧道will be the世界上最大的隧道同类，预计将employ up to 3,000 people。The Fehmarn Belt Fixed Link is a user-financed7 billion Euro project, expected to be completed in nearly nine years, that would connect Puttgarten on the German island of Fehmarn and Rødby on the Danish island of Lolland. Along with the Øresund fixed link between Copenhagen and Malmö, the Fehmarn Belt Fixed Link will bring Scandinavia and Central Europe closer through the named North-South corridor.

Preparing for the tunnel

HolbøllA/S, a Danish construction company carrying out quality work in the fields of soil, concrete, sewerage and coating for both private and public builders, plays an important role on this project with the earthworks for56 bridges在Ringsted-rødby线上，丹麦的主要路线穿越丹麦，隧道将开始。Holbøll对这个欧洲大型项目的承诺包括用于新桥梁的排水工作，以及为桥梁建造坡道。总共三年，预计即将完成，这是公司有史以来最大的项目。

该公司的成功是基于适应市场不断创造的新挑战和变化。这种方法使公司能够赢得Sub合同，以支持Ringsted和Rødby之间的铁路网络。大约130名员工和一个机器公园22台配备机器控制的机器from Leica Geosystems, Holbøll's delivers innovative and sustainable solutions on time and at the agreed price.

在Vordingborg的其中一个桥梁，运营商Flemming Ove Nielsen使用Leica iCON GD4 3D systemon the 61PX Komatsu dozer to do the first rough work for building the slopes.

“对于这种工作，推土机非常有效，因为它可以移动太多污垢，并且通过机器控制，将刀片的正确角度握住，”Holbøll的共同所有人兼董事总经理Carl-OleHolbøll解释说。“弗莱明使用机器控制来创建斜坡，然后挖掘机接管了最终的分级工作，”says Holbøll.

The dual GNSS solution for dozer is an advantage because the slope is so steep, and to achieve an accurate cross-slope, dual GNSS is required.

Further down the rail track by5公里, another bridge ramp is under construction. The excavator usesLeica iCON iXE3 3D system对于坡道斜坡的饰面层。操作员已使用该解决方案来记录不同污垢层的高度，只需放置水桶并让IXE3注册Aus-Build文档和付款释放的高度即可。这saves a lot of timebecause the operator doesn’t have to wait for a surveyor to do the as-built documentation for each layer.

建造一个绿色的走廊

Along with the tunnel, the upgrade and expansion of the rail link between Ringsted and Lübeck will deliver a shorter and faster connection. The Fehmarn Belt Fixed Link is part of the European TEN-T network whose objective is to enhance the efficiency of the infrastructure and reduce the environmental impact. The objective of TEN-T is to transfer more freight from roads to rail, reduce energy consumption and ease road congestion. The infrastructure for rail freight will be significantly improved because freight between Scandinavia and the rest of Europe would no longer need to drive across Storebælt in Denmark, and the rail freight will beshortened by 10 km。

Paving the next steps

负责的公司女性A/S采取了下一步的步骤，开发了将建造隧道元素工厂的区域。持续的考古调查，预备供应基础设施和排水已得到资助55 millio Euros。齿轮传动与徕卡呈HolbøA / S公关equalified for several of the derived projects, including the draining and moving of eight hectares in Strandholm Lake in Denmark.
