Project: Rail infrastructure Alliance Water Main Project Sunbury Victoria

Carrier Size: 355mm HDPE Water Main

Casing Size: PN8 630mm casing (570mm ID)

Run Length: 66m

Spacer Model: HDX-90 (90mm high)

On a recent Rail Infrastructure Alliance project in Sunbury, horizontal and directional drilling specialist contractor Jelmac Directional Drilling utilised Kwik-ZIP HDX-90 spacers to assist facilitate the slip-lining of a 355mm HDPE carrier pipe over a 66-metre run.

Kwik-Zip spacers were specified at 1.5m intervals for this project as per Melbourne Water Retailer Agencies (‘MRWA’) standards.  As the pipes were not being grouted after installation the spacers also need to support the weight of the pipe and water for the life of the installation.

The works were successfully completed at night due to stakeholder requirements.

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 are simple and quick to install and assisted with the sliplining process.” Mick Hemer, Operations Manager – Jelmac DD.

The HDX’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.
