建造北方的威尼斯

作者：Karina Lumholt

瑞典首都斯德哥尔摩面对波罗的海，在梅拉伦湖的14个岛屿上建造。市中心旧城区的Gamla Stan是欧洲保存完好的中世纪城市之一。运河上的许多水道和桥是斯德哥尔摩的特征 - 通常称为Beauty on Wateror simplyVenice of the North.

The region is facing major challenges and the need for improved infrastructure is becoming more and more urgent. With approximately 30,000 people moving to the capital every year, equivalent to two buses full of people per day, Stockholm is currently one of the fastest growing metropolitan regions in Europe. The transport system in the capital is vulnerable because there is only one north-south connection running through this city of great cultural and natural heritage.

Going underground to bypass Stockholm’s traffic bottlenecks

The Stockholm Bypass project, or Förbifarten, is a new21公里的高速公路crossing the Swedish capital, part of the largest infrastructure projects ever made in Sweden. The planning of this 2.7-billion-Euro project commenced in 2006, preliminary construction started in 2014 and the opening is planned for 2026.

Great precautions have been taken to protect the landscape and surroundings that lie above the ground surface. To protect Stockholm’s valuable nature and historic sites, it has been decided to build approximately18公里的总throu 21公里gh tunnels. Under lake Mälaren the construction will have a depth of65 metres below水体。80％的人将通过拥塞费用，由政府资助为20％，但总体公用事业价值被计算出来是从由此产生的经济发展和减少的旅行时间中支付的。估计每天通过145,000辆车，通过城市的旅程将减少到15分钟。

Starting at Kungens Kurva in the south and ending at Häggvik in the north, once the Stockholm Bypass project is finished, it will be the world’s second largest tunnel built in an urban area after the Yamate Tunnel in Tokyo.

在小库尔瓦建筑物

Long-term customer of Leica Geosystems,Skanska Sverige AB, has won the 12.6-million-Euro contract for building the south entrance to the tunnel, connecting it to the E20 motorway at Kungens Kurva, the largest shopping area in Scandinavia and the busiest highway in Sweden. This high-profile project has a strong focus on security and is obliged to not slow down the traffic more than necessary.

Pontus Holmberg在Kurva担任Skanska Sverige的首席测量师。霍尔姆伯格（Holmberg）正在管理现场测量师和主要由不同承包商的钻探者，挖掘机和黑馅饼组成的现场车队，其中许多配备了Leica Geosystems的机器控制解决方案。霍姆伯格与之合作Leica Conx将模型文件转移到机器和现场工作的现场工作人员。

“当与此类网站上的不同承包商合作时，重要的是所有人都必须使用最新的更新文件。”霍姆伯格解释说。“Leica Conxhelps me to track the machines from the office and transfer files to the machine in real time so everybody is on the same page.”

The Epiroc SmartRoc T35 driller working on the site is equipped with a3D机器控制解决方案是由Leica Geosystems量身定制的Epiroc Smartroc制作的and interfaces with Epiroc’s HNS sensor system.

The drill rig follows a digitally-defined pattern to drill holes into the rock for blasting. Traffic is stopped on the two highways that go around the job site, and blasting of the rocky underground is performed every day at either 10 A.M. or 2 P.M. The blasting is done under a carpet of old truck tires that are sewn together to avoid rocks falling onto the two roads.

“如果岩石无意间落在高速公路上，则两个车轮装载机都准备在两侧清理道路，以确保道路在一段时间内被堵塞一段时间尽可能短。”explains Dana Matti, project manager at Skanska Sverige.

公司所有者Nicklas GustafssonGranskogensGräv, is one of the contractors working on site for one and a half years. Gustafsson uses the newLeica MCP80machine control panel on site and he is content with the improvement.“The larger screen is easier to read, and the buttons are improved, so that is a great advantage,”古斯塔夫森说。

Gustafsson explains that it has been a difficult underground with rocks and high ground water level, and when building in the one of the busiest urban areas in Sweden it is important to have reliable technical solutions that minimise downtime.

“解决方案从徕卡呈规则帮助我们保持connected with the site office and make sure that we have a flexible dataflow to support the workflows on the job site.I have worked with the machine control solution from Leica Geosystems on my Liebherr 926 Compact excavator for four years，” Gustafsson解释说。“I am online onCONXfor most of the day and receive my reference files from Pontus directly on the panel.”

列卡地理系统的解决方案是为这个大项目构建互换，隧道和临时港口的多个阶段的关键。机器控制解决方案，总站，棱镜和Leica Geosys亚博5分钟快三tems的扫描仪是在此规模上快速有效地构建项目所需的众多产品中的一些。亚搏彩票手机版下载
