连接丹麦与机器控制

Author:Karina Lumholt

丹麦道路局正在建造40-kilometre motorwaybetween two Danish cities of Herning and Holstebro. At the cost of540万欧元，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。

Leica Geosystems的设备在多个阶段使用该规模的项目。初步调查是在2013年进行的，并于2015年开始了实际工作。

Digging to reveal the past

4 million cubic metres of soilhave been excavated – a cut through the landscape that has given archaeologists a unique chance of exploring the history of the old arterial road between Herning and Holstebro.

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天线，以及Leica Viva CS15field controller, are used by the archaeologists to自动，精确地绘制网站上的发现。

Archaeologists have in average made a finding every500米的挖掘, including a prehistoric sword from 600 AD, a prove of the historic traffic between the two cities for more than 1500 years.

Specialised workers build the motorway

One of the leading construction companies in Denmark,MJ Eriksson, has the contract for an 8-kilometre section of the motorway near the village of Tvis, Denmark. On a typical day, MJ Eriksson has on site for the project:

• 大约30名工人
• Ten dumpers
• 7 Excavators
• 2个推土机
• 1 Grader
• 3 Rollers.

来自全国各地的工人开始在这个大型高速公路项目中工作。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 broad fauna bridge, the largest of its kind in Denmark, has been built to ensure that also red deer can safely cross the motorway.

From office to site

Line Christensen is an engineer working with data preparation at MJ Eriksson’s office in Holstebro. Christensen works with莉卡图标office softwarefor the preparation of the road models that are loaded into the machine control solutions.

克里斯滕森（Christensen）在典型的一天解释了她的工作程序。“我从丹麦道路局收到AutoCAD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软件来转换AutoCAD文件，以创建用于机器控制解决方案的三角剖分文件。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。”她解释说。

Heine Vendelbo是与Christensen接触的运营商之一。他是MJ Eriksson的机器运营商，并在挖掘机，推土机和分级机上使用机器控制。Vendelbo是丹麦最早使用机器控制解决方案的人之一。自1985年以来，他一直在使用机器控制技术，并且是丹麦最早在重型建筑行业实施GNSS的人之一。

“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。”
