Pipe Penetrating Radar (PPR) is the underground, in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-ferrous (concrete, PVC, HDPE, vitrified clay, etc.) underground pipes [1, 2]. The method uses two or more high frequency GPR antennae carried by a robot into underground pipes. The radar data are transmitted to the surface and are recorded together with the output from CCTV (and optionally…

Design of RF tags attaching to buried pipes for enhanced detection by GPR
TLDR
This paper will discuss Bowtie-Omega shaped RF tags and shows how stronger radar signatures are observed when RF tags are buried in a tank partly filled with dry sand.
Automatic Detection of the Grout Layer of Metro Tunnel by GPR
The grout behind the lining segments have a powerful influence on the long-term basis in shield tunnel construction in gravel sand and round gravel layers. Grouting layer detection in the shield
Study of Damage Quantification of Concrete Drainage Pipes Based on Point Cloud Segmentation and Reconstruction
The urban drainage system is an important part of the urban water cycle. However, with the aging of drainage pipelines and other external reasons, damages such as cracks, corrosion, and deformation
Clutter Removal of Near-Field UWB SAR Imaging for Pipeline Penetrating Radar
TLDR
This article investigates some well-known clutter removal algorithms using full-wave simulated data and compares their results considering image quality, signal to clutter ratio and contrast and proposes “modified 2-D SSA,” a complete algorithm chain for pipeline imaging.
An Automatic Tracked Robot Chain System for Gas Pipeline Inspection and Maintenance Based on Wireless Relay Communication
TLDR
A concept of wireless relay communication to assist robot to extend the inspection range, and a newly developed tracked robot chain system that could realize relatively accurate relay transmission and RSSI-based coordinated movement are proposed.
