Large Diameter Pipe Inspection
Large Diameter Pipe Inspection with Multi-Sensor Technology
SewerVUE is dedicated to delivering unparalleled large diameter pipe inspection solutions. SewerVUE specializes in advanced condition assessment, where cutting-edge multi-sensor technologies are utilized to provide our clients with insights into the state of their pipe infrastructure.
Through the use of multi-sensor technologies, SewerVUE also delivers industry leading qualitative data about the pipe’s condition necessary to make informed pipeline rehabilitation decisions.
SewerVUE’s approach to large-diameter pipe inspection incorporates a combination of several advanced sensors: CCTV, True 3D LiDAR, 2D LiDAR, Sonar, and PPR. These state-of-the-art sensors are commonly deployed through remotely operated vehicles (ROVs) or custom-built inspection platforms to ensure thorough and comprehensive assessments.
When inspecting large diameter pipes, frequent problems that arise include 10 meter+ shafts, high flows, and inaccessible points of entry. Mitigate those risks with SewerVUE’ Multi-Sensor Pipe Inspection (MPIS) Float, a remotely operated surveyor featuring cutting-edge multi-sensor technology, including LiDAR, HD CCTV, and Sonar. Equipped with a reinforced tether built to withstand rapid high-flow conditions, it is designed with error correction capabilities to eliminate any disturbances.
Hong Kong Case Study The Multi-Sensor Approch
A case study is presented, showcasing SewerVUE's successful deployment and execution of a multi-sensor condition assessment spanning 10,903.2 linear feet of 47” to 96” reinforced concrete pipe across six critical segments in Santiago, Chile. Over a period of 9 days, SewerVUE employed a combination of 3D LIDAR and CCTV technologies to collect precise measurements. The first deployment faced strong currents during stringing but was successfully completed, with the decision to "free flow" the device for subsequent deployments.
The project encompassed three main pipeline sizes: 57" reinforced concrete pipe (RCP), 47" reinforced concrete pipe (RCP), and 96" reinforced concrete pipe (RCP). The primary objective of this undertaking was to provide an advanced condition assessment using a combination of CCTV and LiDAR technologies. The delivered results included 3D LiDAR data comprising a snake-skin report, cross sections, and a 3D point cloud, as well as CCTV data, including PACP-coded PTZ video and video files.
SewerVUE can tackle big jobs in some of the toughest places on Earth, and get actionable data quickly. Our methods are both accurate and cost-effective. By using remotely operated vehicles to gather data, these methods also eliminate the hazards of man entry surveying methods.
