确保流经运河的光滑流动

Germany’s busy Kiel Canal has been used as an international shipping lane for more than 100 years. Linking the North Sea to the Baltic, the canal enables ships not only to save a distance of roughly 280 nautical miles but also to avoid the potentially dangerous storm ridden conditions of Denmark’s northern Jutland Peninsula - the coastal gale winds and increasingly difficult tidal changes of the Skagerak between Denmark and Norway.

After a century of heavy traffic, German’s Ministry of Transport, Building and Urban De-velopment decided to modernise and carry out safety improvements on the locks of the Waterways and Shipping Authority (WSA Brunsbüttel). The Kiel Canal is one of the most travelled artificial waterways in the world and many countries rely heavily on the canal for the economy of their industries and businesses. Closing the Kiel Canal during this seven-year construction project would be unthinkable since the canal is the lifeline and gate that connects German ports to the Baltic Sea. Therefore, a fifth sluice chamber needed to be added to the existing infrastructure. With an expected completion in 2020, this fifth chamber will handle the shipping traffic while the older locks’ renovation is being carried out.

分析潮汐的兴衰
基尔运河不仅充当运输车道,而且还可以中和北海的潮汐波动和连续波动的锁的水位,随着潮汐变化的变化,六个小时内升高和下沉了大约3米。Brunsbüttel锁系统还为波罗的海臭名昭著的水位差异提供了重要的沿海保护。

The WSA Brunsbüttel has numerous water sensors that continuously collect water level data to foresee any possible water-related difficulties for the locks’ infrastructure and the canal’s surrounding area, supplying vast amounts of back-analysis. A geodetic monitoring system is also onsite and continuously collects massive amounts of data. Further review of the data dictated the need for a programme that could read and combine sensor in-formation into the data processing software.

Before beginning construction, the stability of this enormous project had to be assessed. The new infrastructure presented demanding technical and logistical challenges, which needed to be taken into consideration. The fifth sluice chamber, when completed, will measure roughly 350m in length, 45m in width, with an underwater extending cill on the lock gate at 14m below sea level. The chamber will be built into the sluice island between the large and small locks and requires the removal of roughly 1.6 million m³ of mostly clay soil. Three months of monitoring the existing lock system at Brunsbüttel was necessary in order to analyse the stability of the structure before starting with construction. After the project began, the seven-year construction site will be monitored until its completion.

施工过程中的监视运动
Kirchner Engineering顾问GmbH签订了签约,以监视施工过程中结构的运动。WSA的一个关键要求是将散布在Brunsbüttel整个锁定结构中的现有水传感器中的数据合并,并轻松地将这些信息集成到自动实时的实时地球测量监测分析中。

ALLSAT GmbH, a company specialising in geomonitoring using high-precision total stations and has been collecting geodetic data from the Brunsbüttel for some time, was contracted by Kirchner. The project requires the best possible deviation measurements and GeoMoS Monitor software used by ALLSAT delivers the highest accuracy of +/- 2 mm.

After collecting and analysing new and previous data for three months, the building of the chamber could start. During construction, the chamber walls next to the building site will be continuously monitored three times per hour for any standard deviations (2 mm) and for any deformation activity of more than 15 mm from the position and height of each measured point being monitored.

现有的钱伯斯门和墙壁收集的数据使用了四个Leica Geosystems Nova TM50在整个锁定基础设施的支柱上设置的总站,还使用了Leica Geosystems特殊监测棱镜。亚博5分钟快三

Installations were completed by ALLSAT, who used Leica GeoMoS software for data pro-cessing and visualisations. Communication boxes with GPRS data modems were also in-stalled on top of the measuring pillars using mobile service providers to transfer data. Total stations were also secured by weather element protectors.

Necessity is the mother of all invention
由于WSA所需的特殊要求,Leica Geosystems在其Geomos软件中添加了新的格式编辑器。该新编辑器可以自动从一个或多个来源(例如传感器,数据记录仪,文件或数据库)处理数据。借助此编辑器添加,启用了智能开放界面,允许集成任何逗号分隔值(CSV)文件。在一次性内容配置之后,Geomos CSV模块可以自动从锁上潮汐范围的水位上的水位传感器处理任何新的原始数据内容。每个数据字段在CSV文件中被半彩色分开,收到了某些配置参数,例如时间格式,标识符,观察,单位和位置。有了这些信息,任何CSV文件都可以以预定义的时间间隔进行处理。在这种情况下,将水位的原始数据与大地监测系统的坐标相结合。使用虚拟传感器编辑器,系统可以处理潮汐影响校正的变形,以成为完整的监视分析。

使用此新文件格式编辑器,监视软件变得非常灵活,并且能够读取任何软件接口。通过Internet提供的传感器数据可以快速集成到实时分析中。分析变形耐度水平的大地测量值时,可以考虑到运河水位的所有变化。该软件还将这些数据处理为易于理解的可视化,这些可视化可以根据接收信息的那些负责人的水平和需求进行定制。

Should any of the data measurements exceed the set maximal deformation limits, a sec-ond measurement was made immediately after the completion of that measuring cycle. If this second data measurement still exceeded the maximal allowed limits, the persons responsible at Kirchner were immediately informed by an email message automatically sent in order that they could take the necessary actions.
