To answer this question, it is 1st necessary to comprehend what takes place during the driving of piles with diesel hammers inside "U-formed" qualified prospects:
A micro pile foundation program may very well be advantageous in areas where by big boulders are sporadic while in the subsurface, since the small diameter micro piles may be able to be set up all over such boulders.

As the micropile drilling occurs, a report is stored (typically via the geotechnical engineer) on the thicknesses with the soil and rock layers and also the time necessary to penetrate the rock. Depending on the rock values given within the geotechnical report the engineer designing the micropiles has identified the depth into reliable rock that ought to be needed to have the design loads (rigidity and compression) in friction on the pile on the edges from the drilled gap.
Products utilized for pile cushions are most often plywood or hardwood. Several engineers favor and specify using plywood as a result of regularity in High-strength micro piles the manufactured elements. As in the case of hammer cushions, pile cushions are consumables and get rid of their usefulness during driving. For this reason, a lot of specifications and the "PCI advisable tactics" suggest using a brand new cushion Firstly of driving of each and every pile. When compared for the cost of your pile They can be provided to guard, the cost on the cushion is usually really small and it is usually Wrong economic climate to try to make use of a cushion over and above its handy life.
