What is the definition of ”piling”?

Different types of piling.

Where are the different types used?

Structure of a sheet piling.

Safety conditions.

Sheet-piling


Generally piling is used for:

Establishing of vertical difference of heights (building activities)

Sheet-piling


But is also used for:

Baffle walls

Breaking water

Framing of contaminated areas

Sheet-piling


Technical definition:In technical relation a tightening/securing of soil and/or

water.

Purpose:

Temporary/interims construktions in relation to a building.

Durable/permanent constructions, for example harbours, retaining walls ect.

Following types of sheet-piling walls exists:

Copenhagen walls (Københavnervægge)

Free framed walls of sheet-piling irons

Shored-up framed walls

Sheet-piling



Sheet-piling



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

Sheet-piling



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



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

Sheet-piling



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

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

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


Free framed walls of sheet iron - barriers

Free framed walls of sheet iron - berm

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
