Connecting Denmark with machine control

作者：Karina Lumholt

The Danish Road Directorate is building a40-kilometre motorway在两个丹麦城市和霍尔斯特布罗之间。以成本为代价540万欧元，它将成为longest and fastest built motorway in Denmark。高速公路将将朱塔兰西北部连接到将丹麦与欧洲其他地区联系起来的大型南部高速公路网络。

Equipment from Leica Geosystems is used on several stages for a project of this scale. Preliminary investigations were made on 2013 and the actual work commenced in 2015.

挖掘过去

4 million cubic metres of soil已经被挖掘出来了 - 通过景观砍伐，这使考古学家有一个独特的机会探索赫宁和霍尔斯特布罗之间古老的动脉道路的历史。

3D machine control solutions from Leica Geosystems are used for digging the search trenches to get a sideway (layered) view of the deposits. This establishes if there are archaeological objects in the area and places them in a chronological order. TheLeica Viva GS12GNSS antenna, together with theLeica Viva CS15考古学家使用现场控制器automatically and precisely map the findings on the site。

考古学家平均发现了一个500米的挖掘，包括公元600年的剑，证明了两个城市之间历史悠久的1500多年。

专业工人建造高速公路

丹麦的主要建筑公司之一，MJ Eriksson，有丹麦电视村附近高速公路8公里部分的合同。在典型的一天，MJ Eriksson在现场进行该项目：

• Approximately 30 workers
• Ten dumpers
• 7个挖掘机
• 2个推土机
• 1 Grader
• 3个滚筒。

Workers from all over the country have come to work at this large motorway project.Up to 600 peoplehave at times been working on the site. They are specialised workers who know each other well from other large projects – many of them live together at a camping outside Holstebro during the week.

Glenn Lautrup, one of the men behind this large-scale project, works as foreman for MJ Eriksson and has worked on the project since August 2016. Latrup explains how machine control solutions are used onsite;“Products from Leica Geosystems are used on the entire project, both in the form of machine control solutions and products for grade checking and as-built documentation.”

总预算的25％因为高速公路已被保留用于保存自然。已经建立了几个水道和动物通道通道50 m宽阔的动物桥, the largest of its kind in Denmark, has been built to ensure that also red deer can safely cross the motorway.

从办公室到现场

Line Christensen是一名工程师，在Holstebro的MJ Eriksson办公室工作。克里斯滕森（Christensen）与之合作Leica Icon Office软件为了准备装入机器控制解决方案的道路模型。

克里斯滕森（Christensen）在典型的一天解释了她的工作程序。“我收到了自动加工®丹麦道路局的线文件。对于此项目，我们目前正在研究该文件的第十三版，因为该项目发生了许多更改。然后，我使用Leica Icon Office软件来改变AutoCAD®文件以创建用于机器控制解决方案的三角文件。之后，我将文件上传到Leica Conx，致电机器操作员，并告诉他有一个新的更新文件可用。”

Christensen visits the project daily.“这使我了解了操作员的需求，以便我可以改善文件的准备。”she explains.

Heine Vendelbo is one of the operators that are in contact with Christensen. He works as a machine operator for MJ Eriksson and works with machine control on excavators, bulldozers and graders. Vendelbo was one of the first persons in Denmark to work with machine control solutions. He has been using machine control technology since 1985 and was one of the first persons in Denmark to implement GNSS in the heavy construction industry.

“I am 100 per cent dependent on machine control in my daily work.Before the implementation of machine control, I would have to find a surveyor for the measuring of the area and for placing pegs and strings, and he would have kept a tight watch on my work.”Vendelbo explains.“现在，我只需将文件从Christensen系列的3D模型加载到机器控制解决方案中。我只需遵循模型即可单独进行所有发掘。如果项目有更改，我只需删除文件并将新版本加载到面板中即可。”
