Innovative Solution to Water & Waste Handling - continued
Preliminary specification work was undertaken to determine the appropriate chamber and cover combination for this particular specification.
The Cubis solution for Hazebrouck Water Board used the STAKKAbox ULTIMA Connect with six 3.5 m reinforced load-bearing beams upgraded to B125 classification due to the large stature of the system.
It was decided that the modular STAKKAbox ULTIMA Connect with a bespoke locking AX-S composite frame and cover would be the most suited option due to ease of transport and flexibility during installation.
Made from glass-reinforced plastic (GRP) resin, the high mechanical and chemical properties of the material meant no compromise on strength and durability.
With the light-weight component parts and flat pack option, transportation costs were significantly reduced. Additionally, the need for heavy lifting machinery was eliminated, making labour less intensive, time consuming and expensive. This installation was the largest bespoke frame and cover combination developed to date, spanning over four metres in length.
The 4,000 mm x 3,500 mm chamber measuring 1,350 mm (9 ring sections) in height was delivered to site and assembled by contractor Faignot TP, overseen by Cubis’ Project Engineers.
Forty-two. AX-S Composite covers incorporated three cover sizes - 450 mm x 450 mm, 600 mm x 450 mm and 600 mm x 600 mm.
Each ring section was made up of 28 component parts each connected together using the supplied jointing pegs. For creating the chamber top, an AX-S steel frame and composite cover arrangement was designed and installed.
The flat-pack frame was formed using galvanised steel with two frame-end assemblies and 4 centre assemblies joined together and supported by six 3.5 m reinforced load-bearing beams upgraded to B125 classification due to the large stature of the system.
