Project: Barwon Water DN450 Relocation Project
Location: Marshall, Victoria
Carrier Size: 560mm OD HDPE Water Main
Casing Size: 794mm ID GRP casing
Run Length: 260m
Spacer Model: HDXT-58W (58mm high)
On a recent Water Main Project in Victoria, McConnell Dowell utilised Kwik-ZIP HDXT-58W spacers to facilitate the slip-lining of a 560mmmm HDPE carrier pipe over a 260-metre run.
Whilst not utilised on this particular installation, kwik-ZIP HDXT-58W spacers can accommodate our kwik-ROLLER® wheels. These clip-on wheels are ideal for use in longer runs to minimise wear and to provide significantly reduced co-efficient of friction.
Kwik-ZIP HDXT-58W spacers were specified at 1.5m intervals for this project as per Melbourne Water Retailer Agencies (‘MRWA’) standards. As the pipes would not be fully grouted after installation the spacers are required to support the pipe and water for the life of the installation (Pipe weight – 83kg/m (empty) / 246kg/m (full)).
Kwik-ZIP’s large range of spacers caters for a wide range of carrier / casing pipe size combinations as well as providing flexibility to deal with project alterations.
“Kwik-ZIP spacers were simple and quick to install, and any queries were promptly answered by the sales team.”
Paul Pomfret, Senior Project Engineer – McConnell Dowell
The HDXT’s unique load sharing design maximizes the load bearing capacity of each runner and reduces point loading. The simple and efficient installation process does not require any special tools.
Kwik-ZIP spacers have no metal parts and are made from Kwik-ZIP’s engineered thermoplastic blend that is flexible, extremely tough and has a low co-efficient of friction.
