Platipus B6 Anchor Systems & Platipus S8 Plati-drains
As part of a creek bank stabilisation and remediation project for the Brookside Shopping Centre in Brisbane, Platipus anchoring systems were chosen as the preferred solution to provide stability to an embankment cut adjacent to an existing river water course.
Australian Marine & Civil were awarded the slope remediaton package for the Brookside Shopping Centre project and involved designing and installing embankment stability measures for approximately 200m length of cut slopes, up to 8m in height and ranging from slope batters between 1V:2H to 1V:0.9H. GCS were commissioned by amc to deliver an element design solution using Platipus anchor systems. GCS implemented stringent on-site Australian Standard testing, carried out in accordance with MRTS03, of the Platipus anchor system prior to the project installation and implementation. Design life of the embankment stabilisation project was 60 years.
Australian Marine & Civil installed nearly 600no. Platipus B6 Anchor Systems and 50no. S8 Plati-drains to a maximum depth of 9m into the embankment slope. Each anchoring system was load locked and load verified for a Proof Load of up to 60kN (6 tons) and with a final ‘lock off’ or active Working (Design) Load of 45kN (4.5 tons).
The Platipus anchoring systems were chosen and deployed for the following main features & benefits:
Plati-Drain™ is a unique patented solution that reduces pore water pressure within clay slopes and behind retaining walls.
Plaipus® percussion driven mechanical anchors are a unique, modern and versatile device that can be rapidly deployed in most displaceable ground conditions.
