Material for sheet piling must conform 711.03 which refers to ASTM A328. Sheet piling that conforms to ASTM A328 is acceptable. Used sheet piling may also be used if it meets the project requirements and is approved by the Engineer.
Steel sheet piling is not driven based on any driving criteria, but is driven a specified tip elevation.
Steel sheet piling will normally be driven with a vibratory hammer suspended by a crane or an excavator mounted sheet driver. In difficult driving conditions diesel impact hammers can be used, but it is more likely that the top of the sheets will crush.
Sheet piling is always interlocked with the adjacent sheets. The manufacturer will fabricate a special shape if sharp corners are required in the wall.
