Closed Circuit Television (CCTV) Pipeline Inspection Services
Associated Environmental Services provide a modern
drainage inspection service using the latest closed circuit television equipment.
AES has two camera systems available :
The widely used and well known "Pearpoint
Mainline" system including both the Flexiscan and Flexiprobe camera models. The
Pearpoint Flexscan camera is able to scan at 360° the circumference of the pipe wall at
an 85° angle to the axis of the camera.
The Optimess system is a very high definition,
precision engineered system of German manufacture. The latest KCK 150 Pan & Tilt model
can also scan the pipe circumference at 360°, but is able to view back at about 135° ; a
sort of look over the shoulder effect. This ability to scan back over its forward movement
means it does not matter in which direction the camera is travelling, it is still possible
to look up laterals with superb clarity and depth.
AES has small and large tractors designed to inspect
larger pipes ranging from 400 mm through to 1300 mm and beyond in diameter. The large
Optimess tractor is not only steerable, but is also equipped with a power mechanical lift
so the position of the camera within the pipe can be changed to suit the size of the pipe
at any time during the inspection.
The CCTV equipment is carried in totally self-contained high roof
vans with each unit divided into two work areas. The rear compartments are used to carry
all the camera equipment, including tractors and reels as well as the supporting equipment
such as road signs and cones. The front compartment is set up as a studio the operator
views through the monitor the conditions existing in the line under survey. Each survey
vehicle contains equipment that is able to produce hard copy photographs of any of the
faults as they are detected on the monitor. These photographs can be attached to an
inspection report sheet, thereby providing an immediate reference to the severity of a
fault without having to refer to the videotape. The units are also equipped with the
latest "frame grabbing" equipment, whereby photographs can be taken direct from
the inspection monitor and transferred onto either a 3.5 floppy disc or a CD-ROM for
transfer, along with the inspection reports, onto the client’s computer program. This
information can be entered directly into a computer program to provide detailed line by
line and summarised reports in a format to suit the client’s purpose. Each studio
contains modern computer and printer hardware as well as voice and visual equipment so the
operator is able to maintain contact with his field technician. AES is able to supply
reports based on, and fully compatible with, MITS Hansen system.
