建筑a fast track between Germany and Denmark

Author:Karina Lumholt

The Fehmarn Belt Fixed Link is a planned immersed 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公里长的隧道将是world’s largest tunnel同类，有望最多雇用3,000人。Fehmarn Belt固定链接是用户资助的70亿欧元项目，预计将在将近九年内完成，这将连接到德国丹麦岛上德国岛和罗德比的罗德比。除了哥本哈根和马尔默之间的Øresund固定环节外，Fehmarn Belt固定环节将使斯堪的纳维亚半岛和中欧通过命名的南北走廊更加紧密。

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 bridgeson the Ringsted-Rødby line, the main route crossing Denmark leading where the tunnel would start. Holbøll’s undertakings for this European mega project includes drainage work for the new bridges as well as building the ramps to the bridges. With a total of three years, expected to be finished soon, this is the biggest project the company has ever undertaken.

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之间的铁路网络工作。大约130名员工and a machine park of22 machines equipped with machine controlHolbøll的Leica Geosystems从Leica Geosystems出发，以商定的价格及时提供创新和可持续的解决方案。

At one of the bridges in Vordingborg, operator Flemming Ove Nielsen usesLeica iCON GD4 3D system在61px Komatsu Dozer上，进行了第一个粗略的工作来构建斜坡。

“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。“Flemming uses machine control for creating the slope and then the excavator takes over for the final grading work,”霍尔伯尔说。

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.

沿铁轨沿着5公里，另一个桥梁正在建设中。挖掘机使用Leica Icon IXE3 3D系统for the finishing layer of the ramp slope. The operator has used the solution to document the height of the different dirt layers by simply placing the bucket and letting iXE3 register the height for the as-built documentation and payment release. This节省了很多时间因为操作员不必等待验船师为每一层制作量的文档。

建造绿色的走廊

与隧道一起，环形和吕贝克之间的铁路链路的升级和扩展将提供更短，更快的连接。Fehmarn Belt固定环节是欧洲Ten-T网络的一部分，其目的是提高基础设施的效率并降低环境影响。十-T的目的是将更多的货物从道路转移到铁路，减少能源消耗并轻松道路交通拥堵。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 be缩短160公里。

Paving the next steps

负责任的公司,Femern / S,采取了next steps developing the area where the factory for the tunnel elements will be built. Continued archaeological surveys, preparatory supply infrastructure and drainage has been financed at 55 millio Euros.HolbøllA/S配备了Leica Geosystems，已预先为几个派生项目提供了资格，包括在丹麦的Strandholm Lake的八公顷排水和移动。
