“…The ACPS asbestos cement pipe scanner from Sewer VUE Technology Canada is equipped with a high-frequency antenna (1.6 GHz or 2.3 GHz) for wall thickness and void detection in pipes up to 250~450 mm in diameter [19]. Another of the company's dual-channel equipped MSI multi-sensor inspection robots uses video, laser, and pipe radar technology to inspect underground pipes [17]. The radar data are collected via two independent channels and are suitable for wall thickness inspection of pipes with diameters from 500 to 1500 mm and for locating voids outside the pipe wall.…”

In order to solve the current problems that conventional video inspection can only detect, as an internal pipeline defect and drainage pipeline radar inspection device detects in a single direction and at radar frequency in water pipeline defect detection, a three-channel drainage pipeline ground penetrating radar (GPR) inspection device was designed and developed, the assembly and commissioning of the device prototype were completed, and an actual engineering test application was carried out. Focusing on the problem that the detection direction and depth of the single-channel detection device are limited, a three-channel drainage pipeline GPR inspection device is designed to realize the synchronous detection of the inside of the pipeline, the pipeline body, and the external environment of the pipeline, improving the detection depth and efficiency. According to the design scheme of the three-channel drainage pipeline GPR inspection device, the assembly of the device prototype was completed. The device contains three radar channels, the top of the main frequency of the antenna is 1.4 GHz, the two sides are 750 MHz, the video camera has a pixel count of 4 million, and the positioning accuracy is less than 1 mm, the waterproof grade is IP68, the detection accuracy of pipe deformation (slope) is 0.1°, the detection depth outside the pipe is 1.2 m, and the detection accuracy of corrosion thickness is 15 mm. In a practical application of the device, the Jianguomenqiao sewage pipeline in Beijing, China, was tested, resulting in the discovery of 87 defects, including 39 loose soil areas at the bottom of the pipe exterior, 40 void areas, and 8 cavities.

This article presents a metamaterial-based microwave sensitive sensor with a complementary split-ring resonator (CSRR) structure for nondestructive surface fault detection in pipelines. The CSRR resonator is etched in the ground plane of a microstrip line and is produced using printed circuit board technology. The novelty of the proposed sensor is its structure that allows it to be directly used for nondestructive fault detection in pipelines, based on frequency and Q factor variations, even for faults under a coating. A measurement setup was used to test the proposed sensor in pipelines of different materials: steel, PVC, and aluminum. The sensor could detect faults of 1 mm. For a hole of 1 mm, the frequency shift was 6.10 MHz in steel, 2.62 MHz in polyvinyl chloride (PVC), and 1.70 MHz in aluminum. In some conditions, the Q-factor shift measurements were 6.72, 5.18, and 7.15 for steel, PVC, and aluminum, respectively. The proposed sensor features high sensitivity, small size, simple design, and easy fabrication.

Although the described technologies for digital fabrication (3D printing, laser cutting) have been in use for a long time, the development in recent years allowed these tools to become increasingly accessible. The difference in design and production between the first prototype and the subsequent prototypes can be used to describe the importance of accessibility, visibility and availability of these tools as condition for fruitful usage.xii This section describes literature, preceding work and the results of the first ideation sessions leading to the conceptual design.
