通过检测雷达揭示铁路的地下

Most people walk on the street unaware of what lies beneath their feet. Andre Fischer, electrical engineer and CEO ofFischer Scan，知道有一个复杂的公用事业网络埋在地下土壤中，以支持上面的现代生活。管道，光纤电缆，钢管，电源电缆，通信线等需要准确检测和映射，然后再开始挖掘以避免对公用事业的任何事故或损坏。菲舍尔（Fischer）知道准确定位和放置各种实用程序的重要性，并且已经工作了10年，提供了一流的，非破坏性的测试和地下土壤对象位置服务。

Gearing up to uncover the unknown

GTU Ingenieurgesellschaft mbH, a geotechnical engineering office since 1989, entrusted Fisher Scan with a complex task - detect all metal objects, which could be ammunition rests from World War II, under the rail tracks of Niederhalden’s train station in Germany. Fischer had to accurately position the metal objects in a non-destructive way so the company could install new signal cables under the rail tracks without facing any obstructions.

配备Leica DS2000 utility detection radarandDX办公室视觉utility post-processing software for this task, Fischer collected the Ground Penetrating Radar (GPR) data by effortlessly pushing the DS2000 in single scan lines in area mode to detect the metal objects and utilities. The electrical engineer checked a3-kilometre sectionof the underground along the train track in超过30个地点in an efficient and time-saving way completing the task in just two days.

“Other methods, like trial holes, are too time consuming, could cause utility strikes and have additional costs like manpower and excavators. An alternative metal detector couldn’t be used because there are electricity cables on site,”菲舍尔说。“The DS2000 is compact, easy to set up, and the onboard software permits to check in real time the collected data on site. The efficient work reduced the time the train tracks needed to be closed saving time and costs.”

GPR数据后处理是在DX Office Vision中完成的，以创建对检测对象的专业文档。Fischer使用实用程序后处理软件进行了分析，发现并记录代表嵌入式对象的双曲线。GTU INGENIEURGESELLSCHAFT使用提供给客户的GPR数据，包括所有埋藏的对象和实用程序，以避免在钻孔和挖掘时避免实用程序罢工和弹药。

“我对这种解决方案（DS2000和DX Office Vision）感到非常确信，因为它是可靠的，而且性能高涨，高度高度。该解决方案被证明是用于此类任务的最合适的系统，它使我能够以最有效的方式工作并为客户的项目服务，”菲舍尔说。“The software is intuitive and easy to use and permits to map and verify the data in the office if readjustments are needed.”

释放潜力

The infrastructure that lies below ground must be maintained or repaired continuously. To know the accurate position of utilities, Fischer trusts Leica Geosystems utility detection hardware and software solutions. Equipped with Geosystems technology, Fischer Scan offers competent services in the field of non-destructive testing for building structures as well as the location and positioning of underground pipelines and supply lines using radar and magnetic induction technology. Services offered include:

• Locating and positioning of objects in the ground or concrete
• Scan data analysis consulting in the field and scan data optimisation
• Creation of 2D and 3D scan data and its integration into DXF or DWG data plans.

“我的公司提供了在地下检测和定位公用事业的服务。以Leica Geosystems为我的合格合作伙伴，我有一个完整的解决方案，可以在未来几年成功发展自己的业务。”结论是菲舍尔。
