CCTV pipeline video inspection training for trenchless construction
jobs
Two common types of equipment for CCTV pipeline inspection
It is mainly realized through QV pipeline periscope and CCTV
crawler pipeline inspection robot.
First: the QV pipeline periscope is mainly composed of three parts:
control panel, camera host, and telescopic rod. The whole system
puts the telescopic rod with the camera host into the pipeline to
be inspected, and the camera host transmits the collected images
and videos inside the pipeline to the control panel through
wireless signals. The operator can observe the internal conditions
of the pipeline in real-time and store the collected images and
videos.
Second: CCTV pipeline inspection robot, the main body is composed
of three parts: main controller, crawler, and cable tray. At
present, the main controller generally adopts flat-panel operation.
The operator controls the forward speed and direction of the
crawler in the pipeline through the flat panel and controls the
camera to transmit the images and videos inside the pipeline to the
flat panel through wireless or wired methods. The operator can
monitor the internal conditions of the pipeline in real-time, and
store the original images and videos.
Relevant standards
The Ministry of Housing and urban-rural development issued the
technical specification for the inspection and evaluation of urban
drainage pipelines, the technical specification for the detection
and evaluation of TV and sonar of Shanghai public drainage
pipelines edited by the Shanghai Municipal Drainage Department, and
other local standards.
Practical application of CCTV inspection
Rain sewage diversion pipeline inspection, new drainage pipeline
inspection and acceptance, trenchless repair pretreatment, and
acceptance after solidification.
