From the well known Larssen, frodingham sheet piles and to sheet piles manufactured from Japan, sheet piles technology can be said to be well established. It is documented that sheet piles had been used in civil engineering works for close to two hundreds years.

What are the technology of sheet piles application?

As sheet piles formed an interlocking wall, it’s application can be used in retaining purpose and can be adapted to jobs requirement like : -

* Cofferdams
* Ground Water Diversion/Control
* Barrier for Ground Water Treatment Systems
* Retaining Walls
* Containment Walls
* Flood Protection
* Coastal Protection
* Tunnel Cut and Cover
* Bulkheads and Seawalls
* Weir Walls
* Slope Stabilization
* Baffle Walls

The picture below is an example of a coffer dam. Notice that the cofferdam is being installed by a crane floating on a barge.

Cofferdams can be used on land and in water. The shapes can be of any configuration depending on the structures to be built.

There are many advantages applying the technology of sheet piles . One major advantage is the installation of sheet piles, removed the need for open cut excavation. Open cut excavation required large amount of material to be removed. Using sheet piles, excavation is limited to the exact spot where only excavation is require for work to be done. Thus this minimize waste disposal problems.

The next benefit of applying the technology of sheet piles is the sheet piles are removable once the work is completed. In this sense, the sheet pile is used temporary as a retaining wall while the actual work is done.

Sheet piles can be permanent too as they can be part of the permanent strurtures. As an example, in the construction of basement, the basement wall can be casted with the sheet piles wall. Thus this eliminates the need for exterbal form works for the wall as the sheet piles formed the external form work.

Generally topography and ground water does not hinder the use of sheet piles, thus is is another benefit of applying the technology of sheet piles to construction works with uneven topography and high water table. Finally, using sheet pile, they can be installed to various shape formation required by the designers.

The photo below show the use of temporary sheet piles for retaining purpose, allowing excavation to take place. The excavator at the lower level is excavating down. The orther excavator is installing sheet pile.

Sheet piling consists of a series of panels with interlocking connections driven into the ground with impact or vibratory hammers to form an impermeable barrier. Sheets can be made from a variety of materials such as steel, vinyl, plastic, wood, recast concrete, and fiberglass. It is steel sheet piles that this site will concentrate on. It is in the early 20th century that steel sheet piles to becomes  mainstream, thanks to a German by the name of  Mr Tryggve Larssen .
