Building a fast track between Germany and Denmark

Fehmarn Belt固定链接是一条计划的沉浸式隧道，旨在连接德国和丹麦，使旅行者仅在7到10分钟内通过在国家之间的火车上训练，或者通过四车道的高速公路开车。完成后，这个18-kilometre-long tunnelwill be theworld’s largest tunnelof its kind and is expected toemploy 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 Puttgarden 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.

为隧道做准备

Holbøll A/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-Rødbyline, 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.

The company’s success is based on adapting to the new challenges and changes that the market constantly creates. This approach enabled the company to win the sub contract to support the railway network works between Ringsted and Rødby. With approximately130 employeesand a machine park of22 machines equipped with machine controlfrom Leica Geosystems, Holbøll's delivers innovative and sustainable solutions on time and at the agreed price.

At one of the bridges in Vordingborg, operator Flemming Ove Nielsen usesLeica iCON GD4 3D systemon the 61PX Komatsu dozer to do the first rough work for building the slopes.

“The dozer is very efficient for this sort of work because it can move so much dirt and, with machine control, hold the correct angle of the blade,”explains Carl-Ole Holbøll, co-owner and managing director of Holbøll.“Flemming uses machine control for creating the slope and then the excavator takes over for the final grading work,”says Holbøll.

推土机的双GNSS解决方案是一个优势，因为斜坡是如此陡峭，为了获得精确的跨斜率，需要双GNSS。

Further down the rail track by5 kilometres, another bridge ramp is under construction. The excavator usesLeica iCON iXE3 3D systemfor 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. Thissaves a lot of timebecause the operator doesn’t have to wait for a surveyor to do the as-built documentation for each layer.

Building a greener corridor

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 160 km.

铺上下一步

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量为55毫入欧元。Geared with Leica Geosystems, Holbøll A/S has prequalified for several of the derived projects, including the draining and moving of eight hectares in Strandholm Lake in Denmark.
