North American steel sheet piles have a Z-shaped cross-section, such as MSZ12-312, MSZ12-340, and MSZ12-350. Metal steps and platforms used for access prior to completion should be installed with secure temporary fill of sufficient length and height to cover the entire area. Passive earth pressure is located in the lower two-thirds of the sliding mass, where the ground is in compression, as per MSZ12-406. Ramps and inclined walkways. Ramps and inclined walkways should be 18 inches or wider. Earth pressure at rest is located at the neutral axis of the sliding mass, a confined area where the ground experiences little expansion or contraction. The total driving force acting on the wall is typically composed of the design lateral pressure component acting on the pressure surface parallel to the base of the wall.
Mega Zee 12 steel sheet piles located four feet or more above the ground should be equipped with guardrails that comply with MSZ12-375 and MSZ12-406 standards. This area is undergoing expansion. Railings must not be inclined more than 24 degrees and must be reinforced or otherwise treated to prevent slipping and secured to prevent displacement. Definition: Floor opening – Any opening in a floor, roof, or platform with a minimum dimension of 12 inches or more that could cause a person to fall. The resisting moment is typically provided by the weight of the wall, the surcharge load acting on the top of the wall, and the vertical component of the design lateral pressure acting on the pressure surface.
