WEAP predictions really should be when compared in opposition to real driving conditions to validate their usefulness in pile capacity prediction. The usage of wave equation analysis is a strong Device to assist driven pile installation jobs and when incorporated with higher strain dynamic screening employing a Pile Driving Analyzer (PDA) to confirm hammer effectiveness High-strength micro piles may result in exceptionally efficient pile installation tasks.
In mechanically Energetic environments, which include maritime wave action conditions, the mechanical action brings about the protective layer to become removed and might retain or improve the corrosion fee.
In bigger micropile designs, casing diameter is minimized as the powerful net place readily available for reinforcement is optimized with a single much larger bar compared to smaller bundled bars (see illustration).
