Ensure that sheet piling has a minimum section modulus (SM), (in3/ft [cm3/m]) as specified.
504.3EQUIPMENT
504.3.1 Pile Driving for Bearing Piles 1 Provide
hammers capable of driving piles to specified length and required bearing
capacity. 2 Use fixed or swinging leads constructed to allow free movement of the hammer and rigged
to hold the pile and hammer in alignment during driving. To distribute the hammer blow, fit a helmet around the pile head as needed to prevent the transfer of torsional forces during driving; maintain the proper hammer and pile alignment. Provide hammer cushions of durable manufactured materials in accordance with the hammer manufacturer’s guidelines. Equip diesel hammers with a device, such as rings on the ram, that allows the engineer to visually determine hammer stroke at all times during pile driving. 3 Do not use gravity pile hammers.
The engineer may approve the use of air, steam, hydraulic, or closed end diesel hammers. 4 Submit hammer specifications to the engineer, including the following information:
of the pile hammer;
