在格陵兰建造最长的道路

Author:Karina Lumholt

With a population of little more than 3,000, Qaqortoq is the city with the most residents in southern Greenland. It is also the第四大城市在岛上。

作为格陵兰的所有人口稠密的地方，Qaqortoq均未通过道路连接到其他地方。该市由直升机连接到位于90公里外的Narsuaq机场。这些直升机一次只能运送9人。到达Qaqortoq的唯一其他方法是乘船，只要温暖就可以做到这一点。

运输to and from Qaqortoq is challenging and expensive due to:

• 远距离
• Severe climate
• 困难的地形

实际上，建造新机场的价格要比将城镇与道路连接起来要便宜。一个新的机场对于经济增长，提供就业并鼓励旅游业至关重要，这在格陵兰经济中起着越来越多的作用。

2014年，格陵兰议会，InatsisArtut，授予建设资金6.2 km road通往未来的机场。QaqortoqEntreprenørforretning赢得了合同，并在道路上努力。

自己的冒险

The transportation system in Greenland is truly an adventure. No roads, no railways – nature rules. Historically the major means of transportation have been by boat in summer and by dog sled in winter.

整个国家总共只有150公里的道路，其中只有60公里是铺路。Qaqortoq的6.2公里公路是最长的单路自第二次世界大战以来已经建立了。

Constructing a road in southern Greenland is extremely difficult and expensive. There are no construction materials since the subsoil only consists of rocky mountainous terrain, which must first be blasted and then crushed in order for it to be used as foundation for the road.

“We have used 35 tonnes of explosives to blast 70,000 m3,”explains Lars Motzfeldt Jensen, who is one of the two owners of Qaqortoq Entreprenørforretning.

严峻的冬季气候

QaqortoqEntreprenørforretning已经在其机器上安装了Leica Icon挖掘2D解决方案。但是，该公司最近决定升级到Leica图标挖掘3D解决方案并为其新的Hitachi 350挖掘机购买第二个。

The solutions from Leica Geosystems have工作不断地工作即使在北极冬季的恶劣气候条件下，黑暗后温度为-25°C。

However, there are certain challenges in Greenland as Per Eriksen from Leica Geosystems explains:“500 metres away from the centre of Qaqortoq, we lose the telephone connection. This makes calibration and service of the solutions very difficult. We used radio repeater stations in order to transmit the correction signals from the reference station to the GNSS antennae on the machines.”

根据Jensen的说法，3D解决方案具有节省了很多时间和成本。

Building a road is now more fun

“If we had known that we would save that much time and cost, we would certainly have bought a 3D solution for our driller as well,”said Jensen.

A positive side effect of using machine control has been the increased job satisfaction for the machine operators.

“It’s so much more fun building a road when we use 3D equipment,尼基·戴维森（Nikki Davidsen）说，他是QaqortoqEntreprenørforretning的机器挖掘机操作员。

Ready for building the airport

当新机场被批准进行建设并开始时，QaqortoqEntreprenørforretning已准备好工作。Jensen解释说，该项目将受益于使用Leica Geosystems 3D解决方案。

“We are the best equipped construction company in Greenland, and if the Greenland parliament decides to build the airport, we are definitely ready for the task,”詹森得出结论。
