You will discover amount of components that make the driven pile to undergo deterioration and damages below Operating loads. For instance, inappropriate concrete placement approach that used for concrete during the core of driven shaft, lifting of pile because of floor heave, inadequate concrete in bulb for bulb ended; bored; and pushed pile, Improper space used, and insufficient pushed resistance.
Contractors have carried out a lot of initiatives with nighttime pile driving operations and regardless of Micro pile construction methods the degree of illumination, the aforementioned difficulties along with the hazards they build have to be identified and mitigated accordingly.
