Lightweight Fibrelite covers solve manual handling issues for waste water access point

Project overview

Fibrelite provided a lightweight replacement for previously installed heavy (15cm thick) concrete/steel infill covers at an intersection in the center centre of Innsbruck, Austria.

Problem

Removing the previously installed covers was time consuming due to the covers’ weight (approximately 100kg). A specialized specialised tripod was needed to lift the covers, which was both costly and time consuming. Because the covers were situated on a well used road it was essential to minimize minimise maintenance time and subsequent disruption to traffic.

Solution

In the installation, the oil company used the Fibrelite S14-390-D400 chamber system and KPS piping. The chamber extensions were laminated at the factory before dispatch, reducing the onsite installation time which was a priority. Even with the extensions they are fully vacuum testable and watertight.

KPS piping provides a safe, easy-install solution requiring the minimum possible number of welds. KPS double wall piping requires fewer welds than any other system available, as the compact KPS fittings weld both walls of a double wall pipe simultaneously, again reducing installation time.

Results

Fibrelite’s trench cover design allows covers to be lifted out without specialized specialised lifting equipment. All Fibrelite trench covers can be easily removed by two people using the Fibrelite FL7 lifting handles.
