What does a sheet pile do?
Sheet pile walls have been used to support excavations for below-grade parking structures, basements, pump houses, and foundations, to construct cofferdams, and to construct seawalls and bulkheads. Permanent steel sheet piles are designed to provide a long service life.
What is sheet pile construction?
Sheet piles are sections of sheet materials with interlocking edges that are driven into the ground to provide earth retention and excavation support. Sheet piles are most commonly made of steel, but can also be formed of timber or reinforced concrete.
How deep can sheet piles go?
Combined sheet piling wall beam and pipe king piles are able to go deeper into dense soils than sheet piling sections of a contiguous wall — approximately 6.5 feet (2 meters) compared to 1.5 feet (0.5 meters).
What is the width of sheet pile?
Note that these piles are 700 mm wide.
How thick is a sheet pile?
minimum thickness of 8 mm for GU 12N, to enhance durability; single pile width of 600 mm; ArcelorMittal Larssen interlock; steel grades from S 240 GP to S 430 GP.
What are the disadvantages of sheet piles?
Sheet pile wall disadvantages are:
- Sections can rarely be used as part of the permanent structure.
- Installation of sheet piles is difficult in soils with boulders or cobbles.
- Excavation shapes are dictated by the sheet pile section and interlocking elements.
- Sheet pile driving may cause neighborhood disturbance.
Are sheet piles load bearing?
Sheet piles and box piles
Steel sheet pile section walls are increasingly used for bearing pile applications and in combined loading situations. Applications for permanent sheet pile walls in bearing are used in basements, underground carparks and bridge abutments.
How deep do sheet piles go?
What is the length of sheet pile?
The minimum required length of the sheet pile is 6.892m. Sheet piles having a length of 9m could be used for the construction. If the sheet piles having a length of 9m will be used for the construction, the factor of safety is equaled 1.3.
How long do sheet piles last?
An average good coating will have an effective life of about 5 or 6 years. Poor coating, including poor workmanship, will fail in less than a year, with the best going to an 8 to 9 year life.
How do you calculate the weight of a sheet pile?
The formula for weight calculation is:
- l = length in mm.
- w = width in mm.
- t = thickness in mm.
- η = Specific material density ( e.g.: steel = 7.85 kg / dm³)

What is the most common material used for sheet pilings?
What is sheet piling wall?
Sheet pile walls are retaining walls constructed to retain earth, water or any other filling materials. These walls are thinner in section compared to masonry walls. Sheet pile walls are generally used for following: Water front structures, i.e. in building wharfs, quays and piers.
How is sheet pile calculated?
The design length of sheet pile is L=h+D*FS, FS=1.2 to 1.4. Calculate y = Ha/ p1. Calculate Mmax=Ha[(h-d)/3+y]- p1*y2/2. Calculate required section modulus S= Mmax/Fb.
