WEAP predictions must be compared towards real driving circumstances to validate their usefulness in pile capacity prediction. Using wave equation Assessment is a robust Device to assist pushed pile installation initiatives and when integrated with large pressure dynamic tests employing a Pile Driving Analyzer (PDA) to validate hammer functionality may lead to extremely efficient pile installation tasks.
This is especially handy in the situation of retrofitting. With these kind of micropile drilling rigs, it could allow for for that enhance of the area without the necessity for large disruptions to an operation.
After the micropile casing is drilled towards the demanded depth into the continuous rock, any unfastened materials is blown within the casing, the specialty underreaming bit Micro pile construction methods is compressed and the drill stem and drilling instruments are taken off.
