Australian Bollards Nappe Flow Flexi Splitter Pier Bollard (Splitter pier/Nappe Splitter/Flow splitter/Nappe Blocks/Nappe breakers/Weir bollard), in hydraulic engineering terms, it is a device (fixed vertical fins) designed to break up the flow of water or nappe into several narrower flows.

 

This is to create numerous gaps in the nappe flow and allowing for a combined ingress of air to flow over a dam wall or weir, replacing the use of traditional rigid splitters, with or without shear arrangements.

 

Used also to accelerate the flow, to reduce the potential for severe negative pressures inducted at the zone of impact downstream, to reduce the likelihood of nappe vibration that might cause the failure of a dam wall, by aerating the water flow and to control undesirable sonic effects caused by the nappe flow.

 

They are also used to restrict large flows of storm water, in situations where a storm water management device is designed only to treat small storms.

 

Another further use for an Australian Bollards Nappe Flow Flexi Splitter Pier Bollard (Splitter pier/Nappe Splitter/Flow splitter/Nappe Blocks/Nappe breakers/Weir bollard) is to again break up the nappe so as to allow fish, such as salmon to swim upstream and over small weirs.

 

 

 

 

 

This new development product, of the Australian Bollards Nappe Flow Flexible Splitter Pier Bollard (Splitter pier/Nappe Splitter/Flow splitter/Nappe Blocks/Nappe breakers/Weir bollard), which Australian Bollards have been developing in conjunction with Sun Water Toowoomba Queensland, is to replace the traditional fixed/shear pin Splitter Piers/Nappe Splitters, designed applications as follows:

Australian Bollards Nappe Flow Flexi Splitter Pier Bollard

 

 

Product application/features:

  • - By dividing the Nappe flow into multiple segments.
  • By allowing the ingress of air in the Nappe flow.
  • By accelerating the Nappe flow.
  • Then flexibly bending to horizontal, then returns automatically to the fully vertical position to perform its normal functions, after flood & or high flow events.
  • Then Flexibly bending & deflecting when struck with debris of timber log(s), tree(s) & branch(s), swept along with the Nappe flow during normal or high flood & or high flow events.

Product benefits/consequence mitigation-elimination:

  • - Reducing the potential negative pressures at the zone of impact, downstream of the Nappe flow.
  • - Providing control of the undesirable sonic effects of the Napper flow.
  • Eliminating lost and damaged traditional product & current methods of using fixed splitters.
  • Eliminating the OH&S risks of potential unsafe re-instalment process, of replacing traditional fixed/shear pin Splitter piers/Nappe splitters currently   being used.

Product Solutions/cost savings:

  • - High costly continued product replacement lost/damaged traditional fixed/shear pin Splitter piers/Nappe splitters, during high flood or high flow events.
  • - High costly continued maintenance operations alternative of traditional current potentially unsafe OH&S operations.
