Sheet Piles

A sheet pile is a component part of containment works (sheet piling)which is used above all as a support structure and allows freedom to work and a wide choice of construction solutions to execute various categories of works, such as:
- containment walls for earth, hard core and escarpments;
- support walls and buttresses;;
- excavations in ground and water, demolition;
- quays, groynes of embankments, dykes and outfalls, etc..

Depending on the type of material we differentiate between two types of sheet piling:
- metal sheet piling in which the sheet piles are generally composed of structural metal of various dimensions and sections (larssen type sheet piles);
- concrete sheet piling in which the sheet piles are composed of vibration-consolidated concrete elements of various dimensions and sections.

The advantages of using sheet piling

The main advantages of using sheet piling compared to other support structures are:
- supply of sheet piles already ready for use with specified performance specifications;
- ease of transport and handling on site;
- rapid work progress with a reduction of the duration and costs of the work;
- high corrosion resistance;
- possibility to remove, recover and reuse or recycle as raw material;
- low environmental impact and long durability;
- no maintenance required.

Construction materials and elements

- metal sheep piling.
- concrete sheep piling.

Means of execution

Sheet piles are employed in the following methods:
a. conventional vibration method, carried out by driving in under vibration using a vibrating head, with eccentric weights operated in rotation by an electric or hydraulic motor, suspended from a mobile crane cable or the arm of an hydraulic excavator, holding the sheet pile by means of an hydraulic grab (vice). The vibrator vibrates the sheet pile, the vibrations are transmitted from the vibrating head to the sheet pile which in turn transmits them to the ground around the sheet pile which then enters the ground under its own weight. For removal, the vibrations overcome the lateral friction of the ground and the resistance to the recesses of the sheet pile. The power of the mobile crane completes the removal of the sheet pile.
b. employment with a water jet, a high pressure water jet from nozzles positioned at the end of the sheet pile helps to soften the ground surrounding the sheet pile and to wash (lubrication of the recesses to reduce friction between the recesses and the lateral friction of the ground) during insertion. Water jet-assisted employment is also used for inserting special reinforced concrete sheet piles of differing sections joined to each other by male/female connectors and allows a precise construction of the sheet piling in that it facilitates the positioning necessary for correct vertical and horizontal alignment of the sheet pile on site. The input of water in the right quantity and pressure brings a long-term improvement of the ground mechanical characteristics.
