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


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)



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

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




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!

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.

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

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

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

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.)

Sheet-piling
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

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

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
