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的,知道有一个错综复杂的网络工具that unwind buried in the subsoil supporting the modern life that raises from the ground above. Pipes, fibre optic cables, steel pipes, power cables, communication lines, among others, need to be accurately detected and mapped before anyone starts digging to avoid any accidents or damage to the utilities. Fischer knows the importance of accurately locating and positing every type of utility and has been working for 10 years providing best-in-class, non-destructive testing and subsoil object location services.

Gearing up to uncover the unknown

Gtu Ingenieurgeselgesellschaft MBH是1989年以来的岩土工程办公室，将费舍尔扫描带有复杂的任务 - 检测所有金属物体，这可能是弹药，这可能是第二次世界大战的弹药，在Niederhalden的德国火车站的铁轨下。Fischer必须以非破坏性的方式准确地定位金属物体，以便公司可以在铁轨下安装新的信号电缆，而不会面对任何障碍物。

配备Leica DS2000实用程序检测雷达andDX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 section沿着火车轨道的地下超过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 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，”菲舍尔说。“该软件是直观且易于使用的，如果需要重新调整，可以绘制和验证办公室中的数据。”

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
• 扫描数据分析咨询和扫描数据优化
• 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。
