One example is, a single portion of the location may need a continual really seem rock layer with practically nothing preventing a pushed metal H pile or steel pipe pile from reaching its expected bearing capacity around the rock but One more percentage of the website may have levels of rock not able to carrying the required bearing capacity over the continual sound rock necessitating using drilled micro piles to penetrate the higher layers.
The preferred engineering Remedy is to stop the problem if possible. This is generally not a viable Resolution and the most typical solutions include things like using concrete piles or introducing protecting coatings.

Pile cushions are supplied in different thicknesses and sizes to accommodate the pile along with the push cap, and so are determined by the driving problems as dictated by the dimensions in the hammer along with the soil. As Every single task is different, so tend to be the cushions one of a kind to The actual task at hand. Cushion needs are greatest determined by wave equation analysis, which takes into account the particulars in the pile, hammer traits and also the soil composition.
