瑞士联邦铁路(SBB)与温特图尔市一起启动了一个长期扩张项目,以提高温特图尔火车站的性能。Due to the increasing number of passengers deciding to go with this environmentally-friendly transport alternative – daily around 120.000 people – Switzerland’s fourth-largest railway station required a larger pedestrian underpass in the North for better entrances to the platforms, as well as an adjacent bicycle tunnel which connects the two parts of the city and is also leading to a large bicycle garage. The planned new pedestrian and bicycle underpass also included various stores for an enhanced shopping experience. For this complex project – especially when stopping the rail traffic was not an option – the SBB contractedArgeStraburg(Strabag AG和Burger Stahlbau AG)构造部分,而TerradataAG由承包商选择该项目的整个监控和测量范围。

扩展具有功能性和视觉底色:作为提高旅行和生活质量的镜头,该项目应该有助于将Winterthur火车站变成一个吸引人的城市门入口,连接旧城区中心和城市的新部分。新的行人和自行车地下通道,一个新的物流中心以及骑自行车的人的地下停车位将在选择这种运输工具时提高乘客的安全性和舒适性。

Whenever a project touches people’s lives, especially in terms of their safety, selecting the best partners is of utmost importance.


一个有高安全要求的大胆项目

Winterthur火车站的新的行人地下通道“ Nord”在现有的七个铁轨下通过。为此目的,工程联盟包括Locher Ingenieure AG,,,,F. Preisig AGand10:8 Architekten GmbH,创建了一个50米宽的走廊的概念 - 在四年的建设中,有14个临时铁路桥梁使其越过它。此外,要在项目期间安全地指导行人,PUWI工程联盟为行人计划了一座单独的临时钢桥。由于安全原因,还需要对此临时桥梁进行监控。最后,这个复杂的项目还涵盖了火车站上方的现有停车场,包括通道坡道。停车甲板将在火车站的顶部静态铺设。在地下区域,支柱必须暂时支撑新的地下通道天花板和停车甲板的预先提到的支柱。

在施工,定居和运营轨道的位移,,,,the temporary bridges and the existing parking deck, overlaying the train station, have to be permanently monitored every 15 minutes.

由于铁路需要保持完全运行和安全,监视系统Terradata已安装的警报在检测到定义阈值之外的运动后立即发送警报。这个复杂的项目不仅结合了测量轨道变形,还结合了在停车甲板进行全面大修期间监视其他建筑工艺的结合。由于这些原因,临时桥梁在各端(蓝点)受到磁反射棱镜的监测。在临时桥的前后,每4.8 m(蓝点)进行一次监控。支撑停车甲板的临时支柱(洋红色点),在四个不同的高度水平上进行监测,以检测可能的定居点,同时挖掘其微孔。

The mo精密的区域也必须扩展到邻近的建筑物,以防止结构性破坏并确保人们的安全。Terradata AG使用大地测量和岩土监测传感器收集数据。根据收集的数据,计算了3D变形(例如铁路轨道的扭曲和沉降和其他典型的铁路参数)。

监视超级包装

Terradatarelies on Leica Geosystems’ total stations and its GeoMoS monitoring solution for automatic deformation monitoring, one of the crucial parts being theLeica Nova TM50监视总站。它是监视铁路运营的最佳工具 - 快速而安静,几乎没有被平台上的乘客注意到。

为Winterthur现场选择的设备组合是:

  • 7Leica Geosystemsautomated monitoring total stations
  • 420 glass precise reflective prisms
  • 25用于建筑沉降监测的静静力水平
  • 20 pressure sensors to monitor load
  • 2vibration sensors to monitor structural vibration
  • 40 crack meters to monitor the impact of underpinning the railway building
  • 20 tilt sensors to monitor micropiles

A water levelling system monitored the height of the existing building, and the expanding way of the 40 hydraulic presses was measured by crack meters. Biaxial MEMS sensors monitored the inclination of the micropiles. The monitoring project was continuous (24/7) with a measuring interval of up to 1 minute while activating the load presses.

选择合适的合作伙伴

TerradataAG,,,,瑞士’s largest provider of surveying and monitoring services, took on this exciting monitoring challenge.

“Our solutions aim at early detection and defence against potential dangers – we are specialised in ensuring safety where structures, infrastructures, soil and natural hazards play the main role,” said Martin Rub, Teamleader Monitoring. “The railway project in Winterthur allows us to apply our entire set of equipment and software. We’ve chosen Leica Geosystems’ monitoring solution because we always strive to keep our competitive edge.”

选择Leica Geosystems产品的主要原因是其总站的质量。亚博5分钟快三亚搏彩票手机版下载除了专业的利卡格地理系统监控软件外,Terradata还使用其专有开发特达莫斯(Terradata的瑞士监控解决方案)可视化数据。
