Piling Sheets and Piling Walls

The principal of sheet piling is the creation of long steel structural sections such that, by interlocking of the joints or by fitting together on the longitudonal grooves or by means of special fasteners, it can be used to design a continuous wall. The walls are often used to retain either soil or water. The ability of a sheet pile section to perform is dependent upon its geometry and the soils it is driven into. The pile transfers pressure from the high side of the wall to the soil in front of the wall. There are numerous options and configurations available to meet complex technical requirements with regard to bearing capacitiy, water tightness, pressure resistance and sustainability.

As an effective earth retention and excavation support construction material, basic applications for pile sheet walls are: ports and habour, pumping stations, retaining walls,river revetments, cutoff walls, slope protection and cofferdams and all kind of temorary use for construction works.

The origin of sheet piling dates back more than one hundred years. The first piles were straight web sections. It was Mr. Larssen, State Chief Engineer at the City of Bremen, Germany, who developed the first steel sheet pile, which had a U section shape and riveted interlocks (about 1902). About 1914 interlocking on both sides was first developed and this is still utilized all over the world as the most popular steel sheet pile section. "Larssen" U section sheet piles are famous and well known to civil engineers worldwide. The interlocking system creates a watertight connection and increases the strength of the sheet pile structure. Many years later due to potential structural concerns for the U section interlock the next generation Z-Pile was developed.

Pile sheets are available as hot- and cold-rolled sections. The following list shows some example:

All shapes are designed to construct modular, flexible and adjustable walls. The corner connections are slightly flexible allowing curved segments. Even very complex formations can be achieved in combination with tubular piles or other heavy sections with longitudonal welded connectors. The following illustration shows some possible formations.
