安全前进伦敦
帕丁顿站 - 世界各地着名不仅适用于其创造者isamamard王国布鲁尼尔，而且还为一个爱情熊的小橘子酱。平均每天26,500名乘客从填埋站旅行。尽管其维多利亚时代的优雅和罗西，但是开发了计划，以直接在历史性地标下建造一个全新的地铁站。这项基础设施项目已经由交叉靶进行，并形成欧洲最大的建筑项目的一部分。新站将被称为Crossrail Paddington站。
自2011年7月以来，跨靶制定的计划是为伦敦完成新的地下网络。2011年8月，担任Crossrail Limited的合资企业，Coderain Skanska被授予Crossrail合同405，以完成复杂的14.8英镑的火车项目。该项目正在创建一个主要的新铁路线，从阅读和希思罗到伦敦西部的118公里（约73英里）延伸到伦敦以西，到东方的墓地。它也将直接通过伦敦市中心。新网络现在将连接七个全新的主线地铁站，所有这些都是现有网络铁路服务与伦敦地铁之间的重要交换。其中一个新站是Crossrail Paddington Station。
细致规划，以监测上方和下方的结构
直接在伦敦的核心下工作有很多挑战。该市是超过八千多万人的家，地下每年处理10亿旅程。帕丁顿的新十字架站不仅包括现代建筑，而且是由历史的建筑物。它还位于伦敦中部浓密地区，拥有迷宫管，电缆和下水道，使其成为一个极其复杂的建设项目。由于伦敦被认为是一个全球性的城市，即使对于这个规模的项目，它也必须没有中断。因此，十字架站正在建造为四层的顶部建设，以上与挖掘以上的双向实时流量作为下面的挖掘。
所有这些挖掘,放松Lo中部的污垢ndon could settle unevenly and potentially cause structures to tilt or severe cracking could develop. Constant monitoring of buildings in this area was vital to avoid possible damage and this is how Leica Geosystems products and solutions play an important role in securing the success of this new railway line by monitoring structures and the degree of earth settlement.
Robotic total stations observing Paddington 24/7
COSTAIN-SKANSKA决定通过使用52 Leica TM30的实时监控解决方案，特别是用于监控设计的总站，并在帕丁顿地区和周围的所有类型的监测棱镜上超过1,800个监测棱镜。亚博5分钟快三该设备附在建筑物外面的各种关键位置。从总站收集高精度的3D数据，这些数据测量整个区域的建筑物的各种棱镜的关键参考点。亚博5分钟快三这些测量每天大约8,500点，在日常周期中进行。At the recent phase of the project which was called “the bulk dig”, the data capture for the majority of the area’s total stations takes place at six hour intervals each day, after which the data is sent to be processed with Leica GeoMoS, which sends the results to the web portal before they are distributed to the construction team. The use of Leica Geosystems monitoring sensors, software and communications is vital to the Crossrail project, as these accurate measurements provide information on any variations in structures caused by earth movement and minimise risks, not only to the buildings themselves, but also to public safety.
Automated data processing in near real-time
这些项目需要持续观察，在整个项目的寿命中每天多次重复测量相同的路线和参考点。通过使用机器人总站，可以自动完成此亚博5分钟快三类活动，并直接转移数据以使用Leica Geomos，Geomos调整和GeoOffice软件进行处理。
三个互连服务器用于在CrossRAIL施工现场运行Leica Geosystems软件程序。该软件用于检测和分析站点上方和下方建筑物的地面运动和变形，并有助于加速并简化由总站收集的实时数据高达90％，允许数据亚博5分钟快三从字段快速发行。新的CrossRAIL站的这个软件解决方案完全来自Leica Geosystems，并且是世界上任何地方的最大的唯一地区。康斯坦卡斯卡斯卡合资企业，史蒂夫·瑟格古德，报告
“软件系统必须非常规范和程序来控制项目的质量和可重复性，但也允许环境变化和施工阶段变化。我们的操作不停地运行，我们管理软件系统，以最小化和修复可能发生的任何故障。两个软件系统都记录了与令人惊讶的准确度和精度相关的数据量。“
The Leica GeoMoS software solution is a fully automated system for data generation. It offers automated processing and evaluation using statistical analysis, comparing new data to the original base model by using easy to understand graphs. The software also continuously updates deformation analysis and network adjustment with vast volumes of real-time data received by the 44 to 49 * total stations, resulting in highly accurate data delivered fast.
处理数据时，通过网络调整软件还针对协调几何，地形和精度进行了另外优化。如果任何数据都不在先前收集的数据的±10 mm球体内（通常不超过约6小时），则被认为是不正确的。监督操作的工程测量师对预定义数据参数的偏差进行评估并比较数据，并快速决定是否需要采取措施。
The co-ordination of displaying the processed data with on-site construction teams helps considerably to complete technical work without disruptions. GeoMoS increases not only productivity uptime by displaying real-time data but also simplifies workflows by constantly validating data before issuing it to the teams.
专用的团队和可靠的设备
Dedicated round-the-clock operation and maintenance teams actively maintain the entire Crossrail project’s Leica GeoMoS software solution and also clean and maintain the 42 to 49 total stations and over 1,800 prisms. The total stations take six people to run plus an additional part time support staff of five persons in the field. All involved total stations are serviced and maintained at Leica Geosystems Service Centre in Milton Keynes.
“Crossrail’s motto is ’Moving London Forward‘. Within our engineering surveying team who run the precise levelling scheme and the largest Leica Geosystems homogeneously adjusted total station scheme in the world, we adopted a complementary motto due to the success we’ve had to ’Moving surveying for monitoring forward’. None of the above however would be possible without the continued support of Leica Geosystems and its supply chain partners”, concludes Steve Thurgood, Engineering Survey Manager for Constain-Skanska Joint Venture.
