Aussie Trenchless: the future of pipe rehabilitation solutions
Feb 24, 2023
Aussie Trenchless has been passionate about progressing future infrastructure opportunities and accomplishing superior outcomes since it was founded in 2014.
Aussie Trenchless Director Chris Meredith and the team are committed to pioneering state-of-the-art solutions and furthering business in the trenchless industry. As part of that innovation, the company offers a wide range of unique products both in Australia and internationally.
Aussie Trenchless’s SRP-EXP Spiral Lining System is designed to rehabilitate pipes from DN150 to DN1200 using a selection of six different sized profiles. The SRP-EXP system is a close fitting structural spiral ribbed PVC trenchless pipelining system.
The SRP EXP sizes range from a profile type E7-050-5 for DN150 to DN250 pipes, E9-085-6 for DN300 to DN450 pipes, E14-085-6 for DN375 to DN600 pipes, E20-085-6 for DN600 to DN900 pipes.
Wastewater and sewer pipeline networks are under stress, and as time goes by, underground pipeline networks continue to age and breakdown. Aussie Trenchless believes repairs using traditional civil open cut methods are far too costly and disruptive on communities.
Meredith says trenchless rehabilitation techniques continue to grow in volume as they are a cost-effective repair solution.
“The SRP EXP Spiral Lining System can be installed under flow conditions, with no by-pass pumping needed it is quick and efficient using a third-generation high quality profile to ensure ease of installation, providing a value-added outcome for the network owners,” he says.
The SRP EXP Winding Unit and Cages are a standard design. Each winding unit supplied is the same, the cages vary in diameter to suit the underground pipe size and all parts that make up the cages are standard and interchangeable on some cage sizes.
The special winding machine is positioned into an access chamber or pit, then helically winds the SRP-EXP ribbed strip in order to produce a pipe within the existing pipeline. Aussie Trenchless’ SRP-EXP is first installed at a smaller diameter, then expanded in order to closely fit against the internal surface of an existing pipe.
During this initial wind-in process the spiral pipe lock holds the spiral wound pipe tight to the initial and smaller diameter.
Once the far end of the installation length is reached, the SRP-EXP Liner end is then restrained, with the lock area sequentially released such that the SRP-EXP pipe expands in a controlled manner until it has been pressed hard against the inside wall of the pipe its being installed to.
The installation process is entirely mechanical, meaning that no chemical curing nor steam heating is utilised during the process. Not only is the system easy to install, but it’s likewise easy to remove if necessary.
The SRP-EXP system is capable of negotiating displacement and slight bends while also maintaining a relatively small site footprint. Furthermore, the system is smooth to both work with and install, with minimal and recyclable wastage.
If a client requires a special diameter cage outside of the SRP EXP product range, Meredith says the company can design and supply it.
Spiral lining and pipe segment technology is now available to all trenchless rehabilitation contractors in Australia and overseas through Aussie Trenchless.
