改善首都的铁路基础设施

案例分析

作者:Staff

With thousands of commuters into the capital city every day, additional trains into London are a plus to help with the heavy traffic congestion.

As part of the Brighton Mainline Upgrade Programme, an additional six trains per hour will be made available during the morning peak. Along with this, the programme would also see four additional services into London with a further two additional trains in 2043. Performance will also be improved through the segregation of flows and contribute toward additional train paths on the route.

Topographical surveys are required for this complex and extremely busy piece of London’s railway infrastructure. The programme provides the ideal time to upgrade to newer, faster and more efficient solutions for data capture.

负责该计划的政府实体网络铁路转向阿特金斯进行调查。


A major upgrade

Improving Railway Infrastructure

阿特金斯成立于1938年,是世界上最受尊敬的设计,工程和项目管理咨询公司之一。Atkins与来自公共和私营部门的不同部门和地区以及地方和国家政府的各个部门和地区的广泛客户紧密合作,提供了长期可信赖的合作伙伴关系,以创造一个通过实施思想来丰富生活的世界。

总部位于英国萨里的克罗伊登(Croydon)的阿特金斯铁路部(Atkins Rail Division)使用Leica Geosystems测量设备已有近20年的历史。该决定是去年决定取代咨询公司(Leica System)1100和1200个电台的大多数值得信赖但老化的车队,并使用最新的Leica Captivate Solutions增加了公司现有的GNSS,数字级别和遍历设备。bob apple

这次重大升级看到了广泛的工具:

  • 1 Nova MS60多阶段
  • 7 Viva TS16I成像总站bob apple
  • 4 Viva GS14 GNSS智能天线
  • 10个CS20控制器
  • 2个CS35 CS35平板电脑
  • 2 LS15自动焦点数字水平
  • 8个全遍布套件

With the new portfolio, Atkins was ready to take on the important rail project.


Site limits and challenges

Improving Railway Infrastructure

为了使伦敦维多利亚和伦敦桥的其他计划路径,需要在风车桥交界处隔离流动。它将支持通过钥匙列车流的隔离路线上的绩效改进,该钥匙列车流目前会在其他相邻线路和更广泛的南伦敦网络中转移反动延迟。

为了在东克罗伊登(East Croydon)实现额外的火车停车能力,需要建造其他平台。除了安全地在Selhurst和Gloucester Road Junction之间提供12辆车的火车运营外,还需要基础设施来容纳Selhurst Spur上的12辆车火车。

结果,开发了可行性选项以实现这些输出。选项包括:

  • 风车桥交界处的等级分离,
  • Extension of the Selhurst Spur
  • 风车桥交界处和东克罗伊登之间的其他轨道
  • East Croydon的另外两个平台。

据确定,在East Croydon站需要工作,以安全地提供所需的乘客进入新平台,并在大厅上提供足够的增加乘客容量。

“与所有铁路地形调查一样,站点访问的局限性和铁路基础设施的性质限制了我们进行调查的方式,” Atkins Track Track Team Project Project Project Project Project Project Project Project Project Project Project Project Manage。“在该规模的项目区域尤其如此,考虑到基础设施部分可用的复杂交界处和火车路线。”


Leica Caintivate解决方案帮助铁路世界

凭借在铁路环境中的准确性和可靠性,阿特金斯(Atkins)求助于Leica Geosystems的解决方案和技术,以避免在昂贵和时间限制性轨道拥有期间昂贵的停机时间。在这种情况下,新的Leica Captivate系列中可用的最新创新是无价的。

The Leica Nova MS60 MultiStation, with its wide spread of functionality including the ability to scan up to 1,000 points per second, was used on the project. Combined with the imaging capability on all the total stations and the interoperability of these with both the Leica CS20 controller and CS35 tablet computer, this enabled Atkins to capture every necessary detail in the quickest and most effective way.

GNSS智能天线使用相同的控制器和迷人软件,以使用HXGN SmartNet校正服务快速准确地建立控制。除了迷人的软件外,还使用了最新的LEICA LS15数字级别,具有成像和自动焦点,从而可以在恶劣条件下更快,更准确的员工阅读。这些仪器还与轨道巨魔一起使用,并与Leica Geosystems激光扫描解决方案一起使用。

提供和开发项目设计人员的地形调查数据和选定的点云提供了合理的铁路基础设施设计,该设计将增加南伦敦铁路网络已经包装的部分的容量。最终,这将使历史轨道对齐,使其适合于2020年及以后的铁路扩展。

The project and the data provided to it will lead to providing a better railway experience for the growing customer base and will be used to support economic growth of the surrounding areas.


向伦敦的铁路基础设施提供地形调查

对于阿特金斯来说,Leica Geosystems Solutions为该项目带来了许多好处。

Groboljsek说:“通过采用Leica迷人的软件技术,我们可以为网络导轨提供快速准确的数据实现,避免昂贵的回报,并节省时间和精力,同时也降低了风险。”“通过使用Leica GeoSystems解决方案的组合,可以安全,准确,有效地收集数据,尤其是在轨道访问权限期间的有限时间内收集数据。减少在赛道上的时间降低了基于现场的风险,并减少了对阿特金斯人员受伤的风险。此外,网络铁路财产和基础设施的风险降低了。”

Primary and secondary control was established using the fast and accurate Leica Viva GS14 GNSS Smart Antenna, using both post processed and live RTK data from HxGN SmartNet. The service was also used to increase efficiency by assuring the quality of 3D GNSS data directly in the field.

With intuitive and understandable software in the field and in the office, Captivate allowed instant 3D visualisation of the survey data collected on the railway site, providing a detailed understanding of the project requirements.

The Leica ScanStation P40 laser scanner also offered a fast scan rate with less noise and clearer scans along with streamlined workflows from the field to office and back via easy automated processing with Leica Cyclone laser scanning software. This was then all quickly and easily communicated to all staff and to the client using Leica TruView.

完成后,Brighton Mainline升级计划是第一个在项目生命周期中更早使用地形调查的研究之一。结合Leica Caintivate Solutions,铁路项目的交付顺利进行,使设计团队和测量师可以根据即时反馈主动管理和传输决策。
