Read the Case Study
A third-party engineering and construction company contacted Fibrelite to provide a bespoke GRP composite trench covering arrangement to fit precast concrete service trenches at a UK airport maintenance facility.
The concrete troughs had already been sourced, and sizing and specification finalised, making a custom Fibrelite covering solution an ideal solution.
The fact that the concrete troughs had already been acquired prior to Fibrelite’s involvement in the project presented a number of design challenges, as well as those related to the nature of the application.
Key design challenges:
- Custom cover dimensions to fit existing troughs.
- E600 ‘Super Heavy Duty’ load rating essential due to frequent high wheel loads.
- Every third cover required 140x50mm apertures for access to compressed air lines.
- Non-standard colour pigment requested.
In addition to the above, a strict construction programme was mandated.
Fibrelite proposed a custom, retrofit GRP composite trench cover design which would fit directly into existing troughs. This design was approved by the client shortly after submission.
- Custom covers, dimensionally consistent to all details provided by the client, allowing them to be fitted immediately into existing trough rebates upon delivery.
- Covers stepped from 40 to 65mm deep in order to accommodate E600 load rating.
- Every third cover modified with 140x50mm ‘mouse hole‘ aperture to enable easy access to compressed air lines.
- Covers manufactured using Light Grey colour pigment.
Covers were manufactured and delivered before the project deadline.
Fibrelite covers enable easy safe manual access to trenches, eliminating the need for specialist personnel or machinery during maintenance or operation (and resultant costs).
Key benefits of Fibrelite covers:
- Best strength to weight ratio available in the market today.
- Easy, safe access to trench services using the Fibrelite’s ergonomically designed FL7 lifting handles.
- Fit-and-forget corrosion-free long-term solution.
