As each challenge is different, so are the cushions distinctive to The actual project at hand. Cushion necessities are finest determined by wave equation Investigation, which takes into consideration the particulars with the pile, hammer traits plus the soil composition.
In the Karst sort scenario where the higher rock layers are divided by unstable, occasionally zero blow rely, materials the micropile will have to be cased even though drilling to the continuous rock. The drilling is attained utilizing a down the hole hammer (DTH) with a bit that extends slightly beyond The underside on the casing and will expand to cut a gap inside the rock somewhat larger than the casing diameter.
Extra sections in the casing are combined (jointed) to forestall the borehole from collapsing throughout drilling.
