Revealing rail’s underground with detection radar

Author:Renata Barradas Gutiérrez

Most people walk on the street unaware of what lies beneath their feet. Andre Fischer, electrical engineer and CEO ofFischer Scan, knows there is an intricate network of utilities 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.

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 Office Vision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。电气工程师检查了3-kilometre sectionof the underground along the train track inmore than 30 locationsin 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是紧凑的，易于设置的，并且机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。”

探地雷达数据后期处理完成在DX办公室粘度ion 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.

“I’m very convinced about this solution [DS2000 and DX Office Vision] because it is reliable as well as fast and highly performing. This solution proved to be the most suitable system for this kind of tasks and it allows me to work in the most efficient way and serve my clients’ projects,”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.”

Unleashing the potential

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.

“My company offers services to detect and position utilities in the underground. With Leica Geosystems as my competent partner, I have a complete solution to grow successfully my business over the next years,”concludes Fischer.
