MiraCell™ Perforated Cellular Confinement System MiraCell™ Standard Perforated Cell MiraCell™ Large Perforated Cell
|
MiraCell™ large perforated section dimensions shall be as indicated "MCLP-D-XX" where "MCLP" indicates a MiraCell™ large perforated cell; "D" indicates the cell depth in mm and "XX" indicated number of cells in the expanded length. An example of MiraCell™ Large Perforated section nomenclature is MCLP-150-30 where the section cell depth is 150mm and the length over its 30 cells is 12.19 m
MiraCell™ large peforated cell cellular sections (MCLP) shall be fabricated using strips of sheet polyethylene each having a length of 3.35m and a width equal to the cell depth. Adjoining strips shall be connected using uniformly spaced, full depth, ultrasonic spot welds. Welds shall be off-set and aligned perpendicular to the longitudinal axis of the strip. Weld spacing shall be 660mm ± 2.5mm. The ultrasonic weld melt pool shall not exceed 25mm.
