It allows for the creation of piles that have a significant axial load capacity as opposed with other options. They can be simple to install even in confined Micropile design specifications Areas, and there aren’t any vibrations that could damage surrounding constructions.
Casings are filled with self-consolidating concrete and reinforcing metal as required. This mixture of metal casing, reinforcing steel and concrete fill results in load bearing capacities equal or larger than driven piles.
Using the Improper measurement or thickness of hammer cushions or lousy cushion routine maintenance could potentially cause considerable harm to the hammer and, in Extraordinary cases, expose the crew and immediate area to the possibility of injuries or injury as a result of failing (and falling) parts with the hammer.
