In the methods of underground pipeline inspection, CCTV pipeline inspection technology excellently reflects the significance of technological advancement. With the emergence of this technology, it has changed the traditional form of manual well inspection, greatly improving the efficiency of pipeline inspection and reducing the risk for well operation personnel.
Small in size, equipped with an HD camera and spotlight on its head, connected to a controller through a power line at the other end. This machine, resembling a mini car, is a CCTV sewer inspection robot.
Don't be fooled by its tiny appearance—it has big capabilities. Using the pipeline inspection camera system, it detects and records the conditions inside the pipelines such as rust, scale, deformation, collapse, perforation, and cracks, and saves the video footage transmitted to the surface. Technicians interpret the footage, analyze the current state of the pipeline using professional knowledge and software, determine the nature of the defects, and accurately locate them, thus helping us scientifically and comprehensively understand the condition of the pipelines.
Operational Condition Detection of Existing Drainage Pipelines
Managing, maintaining, and operating existing drainage pipes requires CCTV inspection technology to understand the functional and structural status of the pipes, assess the operational state of the existing drainage pipes, promptly clean and treat the pipes, and replace aging drainage pipes to ensure normal operation of the pipelines. However, high water levels in pipes during the application of existing drainage pipes become an important obstacle to the application of CCTV technology.
Structural Safety Inspection of Newly-Built Pipelines
The structural safety inspection of newly-built pipelines mainly involves understanding the structural safety status of the new pipelines, and promptly identifying structural defects like cracks, misaligned joints, and dislocations to address defects in the early stages of construction, in cooperation with constructors.
Structural Safety Detection for Ground Collapse
By using CCTV inspection technology, major structural defects such as severe cracks, misaligned joints, and deformation causing ground collapse can be identified. Combined with surface inspection technology, the impact of defects on ground collapse can be analyzed, evaluating the hazards posed by the defects, thereby providing important technical basis and data for the discovery, inspection, and treatment of ground collapse hazards.
Pipeline Direction Inspection
Using CCTV sewer inspection robot to enter the pipeline can confirm the internal route of the pipeline and identify the connections within the pipeline, thus clarifying the direction of the drainage pipeline.
The main task of CCTV sewer inspection robot's inspection is "patrol inspection," with the primary goal of discovering blockages and leaks, and acting as a "guide" for worker repairs. It's important to note that drainage pipelines are prone to blockages or leaks, and manual inspection has certain limitations, which has become a headache for many departments. The use of CCTV pipeline inspection technology is a good start. It is believed that in the future, the sewer pipe cleaning machine will not only probe the conditions inside the pipeline, and discover blockage and corrosion points, but also perform unblocking and leak repair tasks. With the progress of technology, these possibilities could very well become a reality.
