The Culvert
We were required to carry out a detailed examination of a single bore culvert. This culvert has never had a detailed examination due to its Dia. of approx. 450mm and length of 78m.
The culvert headwall was at the base of an embankment over 21m from the track. Access was on foot down the embankment.
The Equipment
Trak Dakk was used to examine the barrel due to its small size and the fact that it could easily be carried to the headwall. It was fitted with the spiked rubber tracks and Wi Fi was enabled to allow the footage to be viewed on 2 separate screens.
The Team
To carry out the examination a team of one STE4 examiner and one operator was used. The operator drove the crawler through the culvert whilst the STE4 carried out the examination.
The Examination.
The invert was found to contain silt, debris and water.
The unit passed over these obstacles with ease going on to discover defects that required the examiner to report an urgent defect.
