通过检测雷达揭示铁路的地下

作者：Renata BarradasGutiérrez

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，支持从上面的地面上产生的现代生活。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。

准备发现未知的

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.

Geared up with theLeica DS2000 utility detection radar和DX办公室视觉实用程序后处理软件针对此任务，Fischer通过在区域模式下以单扫描线以单扫描线以检测金属对象和实用程序来毫不费力地将DS2000推送出来，从而收集了地面穿透雷达（GPR）数据。电气工程师检查了3-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,”said Fischer.“ DS2000紧凑，易于设置，并且板载软件允许在网站上实时检查收集的数据。高效的工作减少了火车轨道需要关闭的时间和成本所需的时间。”

GPR data post processing was done in DX Office Vision to create a professional documentation of the detected objects. Using the utility post-processing software, Fischer analysed the B-scans, finding and documenting the hyperbolas that represent the embedded objects. The GPR data provided to the client, including all the buried objects and utilities, were used by GTU Ingenieurgesellschaft to avoid utility strikes and ammunition hits while drilling and digging.

“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，”said Fischer.“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:

• 在地面或混凝土中定位和定位物体
• 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。
