Following types of sheet-piling walls exists:
Copenhagen walls (Københavnervægge)
Free framed walls of sheet-piling irons
Shored-up framed walls

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

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

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
![Page 15: Sheet-piling Copyright 2005 © Nicolai Green Hansen What is the definition of ”piling”? Different types of piling. Where are the different types used?](https://reader035.vdocument.in/reader035/viewer/2022062404/551a69db550346b52d8b4c67/html5/thumbnails/15.jpg)

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!

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
The terrain above the wall must nok be loaded by digged up soil, building materials ect.
There must nok be any settlings sentisive constructions nearby

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

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

Shored-up framed walls – the 3 stiffening methods
Slantingly stiffening – with stringpiece
Mutual - with stringpiece
Injected with anchor

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.)

Shored-up framed walls– mutual with stringpiece
If there are a opposite framed wall this can be used as retain
The width of the excavation must maximum be 10 meter

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

Safety
ALWAYS get specialists to dimensionate sheet-piling walls
Think on your and others safety during the works execution
Do NEVER remove stiffenings ect. even if they are in way
If you observe any suspicious then NOTIFY construction site manager or the authorities
Do NEVER compromise even in pressed circumstances
Life is to short for ACCIDENTS
