Hollow bar applications reduce the necessity for short-term casing in collapsible soils and also give elevated grout permeation and efficient micropile diameter, expanding capacity.
Pile cushions, since the title implies, are largely defense to the pile exclusively, precast concrete piles. Pile cushions secure the ends with the pile from spalling injury that would happen in the event High-strength micro piles the hammer blow impacts the pile. The cushion also offers attenuation in the blow through driving, lessening tensile forces performing around the pre-stressed pile as it can be driven. Pile cushions are furnished in numerous thicknesses and sizes to support the pile along with the travel cap, and so are based on the driving ailments as dictated by the size of the hammer and also the soil. As Each individual job is different, so would be the cushions one of a kind to the particular project at hand. Cushion necessities are finest based on wave equation Investigation, which requires into account the particulars from the pile, hammer features as well as the soil composition.
