AWMA’s unique pneumatically actuated tilting LayFlat Gate system provides a 15m breadth of open waterway for the clear passing of flood flows.
Standard headstocks contain gate actuation systems which impede the flow passage, making them subject to damage during flood events.
The original Quambatook Weir located in northern Victoria contained eight bays of manual stopboards which suffered structural damage during the 2011 floods.
The unique air operated actuation system offered by AWMA allows the single piece gate leaf to be raised up from the base requiring no overhead structures. This design reduces the issues associated with debris becoming entrapped on piers and walkways. An automatic locking device supports the gate in the raised position.
AWMA and APCR McDonald Construction have completed the refurbishment of the Weir which will allow the Gannawarra Shire to maintain an upstream weir pool whilst accommodating flood waters.
Gannawarra Shire Councillor Neil Gannon said that upon completion of the reconstruction, the Quambatook Weir will become an important asset to the community “The sections of the manual flood gate boards are being replaced with one full width air operated gate that will be controlled from the bank which will allow for unimpeded flow”.
The new Quambatook weir was officially opened by Peter Walsh Member for Swan Hill with over 50 people in attendance.
