CCTV Pipeline Inspection is a pipeline inspection robot system that can be used for internal camera inspection and measurement work of drainage pipes. It has strong power performance, excellent driving and obstacle-clearing capabilities, and can operate normally even under harsh pipeline conditions.
CCTV Pipeline Inspection mainly involves using closed-circuit television recordings to enter the drainage pipes with camera equipment, transmitting image data to the control computer for data analysis. It can carry out image processing, record the rotation and positioning of the camera, and has high-quality image recording and text editing functions. Its main working components are a four-wheel-drive camera vehicle and a computer.
Compared with traditional pipeline inspection methods, it has the following obvious advantages:
No personnel need to enter the pipeline directly, completely avoiding potential personal accidents;
By utilizing modern technology, work efficiency and quality have been greatly improved, allowing faster and more accurate detection of issues inside the pipeline, identifying the root causes of problems, significantly reducing troubleshooting time;
Provides reliable and accurate basis for determining pipeline repair, clearance, and cleaning schemes;
Offers a scientific and effective method for pipeline construction completion acceptance and inspection of pipeline conditions.
Components of CCTV Pipeline Inspection Equipment
CCTV Pipeline Inspection equipment mainly consists of a camera crawling system, control cable, and control console.
Camera crawling system: The crawling system propels the camera equipment into the pipeline, capturing images of the pipeline interior with the camera system and transmitting the images to the control console in real-time;
Control cable: Responsible for transmitting instructions to the crawling device and real-time image data;
Control console: CCTV core operating system, responsible for issuing control instructions such as advancing and retracting the crawling system, camera system lighting, etc.; receiving image data and storing image data in storage devices.
Uses of CCTV Pipeline Inspection Equipment
By operating the main controller's human-machine interface, control the crawler to move inside the pipeline, transmitting the collected pipeline internal images in real-time to the main controller for real-time monitoring. Detect and image rust layers, scale, corrosion, perforations, cracks, etc., inside the pipeline and evaluate them based on the inspection technical regulations, providing important basis for creating repair plans.
According to the "Technical Regulations for Urban Drainage Pipeline Inspection and Assessment" CJJ181—2012, "Technical Regulations for the Maintenance of Urban Drainage Channels and Pump Stations" CJJ68—2007, "Technical Regulations for Urban Drainage Pipeline Maintenance Safety" CJJ6—2009, and "Construction and Acceptance Specifications for Water Supply and Drainage Pipeline Engineering" GB50268—2008, evaluate the structural and functional condition of the inspected pipeline and provide recommendations for repair and maintenance based on the actual inspection results.
CCTV Pipeline Inspection technology has not been in use for long but has developed very rapidly. In some developed countries and regions internationally, it has been widely applied for systematic inspection of drainage pipes, preventing pollution caused by leakage, and monitoring and preventing geological disasters (such as landslides). In recent years, some major cities in China have started using this inspection system and achieved very good results.

Inserted Lining High-Density Polyethylene (HDPE) Pipeline Repair Technology
Inserted lining high-density polyethylene (HDPE) pipe is a brand new pipe rehabilitation technology. The technology is to insert a HDPE pipe of suitable size into the old pipe that needs to be repaired. It takes advantage of the rigidity and strength of the old pipeline as the bearing structure, as well as the characteristics of HDPE pipe's corrosion resistance, wear resistance and permeability resistance, to form a "pipe in pipe" composite structure, so that the repaired pipeline has the comprehensive performance of steel pipe and HDPE pipe. This technology, by using the feature of HDPE pipe that it can automatically recover its original physical shape after deformation, is to retract HDPE pipe with special equipment. Before inserting, the lining pipe is pulled into the target pipe with a certain traction force as well as speed. Then the pulling force is removed and the liner is restored to its original diameter and tightly bonded with the outer pipe. The outer diameter of the lineing pipe is slightly larger than the inner diameter of the original tube. After the lining is completed, the lining pipe and the original tube are firmly combined and the thickness of the liner can be designed according to the needs.

Trenchless Rehabilitation Technology and Application of Pipeline Lining
Since the rise of pipeline trenchless rehabilitation technology in developed countries in the 1980s, it has become a widely used method for underground pipeline rehabilitation. By avoiding large-scale excavation, this technology reduces the impact on urban traffic, the environment, and residents' lives, hence gaining extensive attention and preference. This article will provide a detailed introduction to the main methods and application fields of trenchless rehabilitation technology and analyze its important role in urban network renovation.
