Bauer has not revealed whether it plans to launch new equipment at this year’s Bauma construction equipment exhibition in Munich, Germany this April but it hopes to win an innovation award at the event.
The company’s Mixed Drilled Offshore Steel (Midos) pile system has been nominated for the Bauma Innovation Award 2016 and the results will be announced at a ceremony the day before the exhibition opens.
Bauer has said that it developed the system as an alternative to driven tubular steel piles that often do not achieve the required strength in calcareous sand deposits due to crushing of the sand by the dynamic load during driving. The current method to overcome this issue is to grout the pile or pre-drill the hole but this can create other technical issues.
Bauer worked with University College Dublin to develop Midos, which used mixed in place methods using special steel casings with openings to allow concrete to flow through and anchor the pile in position.
Initial tests have shown piles to achieve capacities of up to 9,000kN in silica sand and the method has also been tested successfully in calcareous sand deposits.
According to Bauer, the drilling process is significantly quieter than the current driven alternatives which will minimise the impact on aquatic life.
