Sheet-piling Following types of sheet-piling walls exists: § Copenhagen walls (Københavnervægge) § Free framed walls of sheet-piling irons § Shored-up framed walls Copyright 2005 © Nicolai Green Hansen

Sheet-piling Copenhagen walls (Københavnervægge) Copyright 2005 © Nicolai Green Hansen

Sheet-piling Copenhagen walls (Københavnervægge) § Vertical HE - profiles § Distance: 0, 5 til 1, 5 meter § Supplementing: Planks/iron sheets possible gunite § Fine in dry sand § Also fitted in cohesion soil (clay) possible without completing or with gunite § Not fitted under water surface in sand layer (the wall are not watertight) Copyright 2005 © Nicolai Green Hansen

Sheet-piling Copenhagen walls (Københavnervægge) § Profile irons is ramed down as traditional piling or by pressing – eventual there could be predrilled to bottom of excavation and then ramed down § Alternatively there can be ramed down to the level of the tip and subsequent concrete are deposit to excavation level Copyright 2005 © Nicolai Green Hansen

Sheet-piling Copenhagen walls (Københavnervægge) § Can be performed as free wall under following assumptions: § Deep of excavation do not exceed 3 -4 meters § There must not be settlings sentitive constructions nearby Copyright 2005 © Nicolai Green Hansen

Sheet-piling Copenhagen walls (Københavnervægge) § Can also be done as a shored up wall – as shored up framed walls § Shoring up should always take place if any of the mentioned assumptions ain´t fullfilled § REMEMBER: Safety above all! Copyright 2005 © Nicolai Green Hansen

Sheet-piling Free framed walls of sheet iron § Performed with special iron profile with locks § The walls are water tight § Good where water level is higher then the level for the excavation § A free sheet piling wall must maximum be 3 -4 meter because water- and soil pressure can bring big deformations § There must nok be any settlings sentisive constructions nearby § The terrain above the wall must nok be loaded by digged up soil, building materials ect. Copyright 2005 © Nicolai Green Hansen

Sheet-piling Free framed walls of sheet iron Surface loads can be minimized as followed: § Closing of the area behind the sheet piling wall § Excavation in the shape of a berm behind the sheet piling wall Copyright 2005 © Nicolai Green Hansen

Sheet-piling Shored-up framed walls § Used when the excavations are deeper then 3 -4 meter § Are economical better when the digging depth are big (less material consumption than by free walls) § Cause substantial less horizontal deformations Copyright 2005 © Nicolai Green Hansen

Sheet-piling Shored-up framed walls – the 3 stiffening methods § Slantingly stiffening – with stringpiece § Mutual - with stringpiece § Injected with anchor Copyright 2005 © Nicolai Green Hansen

Sheet-piling Shored-up framed walls – slantingly stiffening § A wood/steel profile which are secured to a foundation in the bottom of the excavation up to a horizontal stringpiece § The foundation can maybe also be combined with the building construction (floors ect. ) Copyright 2005 © Nicolai Green Hansen

Sheet-piling Shored-up framed walls– mutual with stringpiece § If there a opposite framed wall this can be used as retain § The width of the excavation must maximum be 10 meter Copyright 2005 © Nicolai Green Hansen

Sheet-piling Shored-up framed walls – injected with anchors § Are really specialist work § Used by big excavation deeps § The big advantage are the free space in the excavation § Can be established in more levels § A thorough inquiry of the underlying soil volume must be performed thus supply pipes ect. ain´t damaged Copyright 2005 © Nicolai Green Hansen
