You happen to be awarded a position on an outdated venture worksite. The site has several small-diameter pushed steel pipe piles (twelve inches or fewer) with the longest pile being a hundred ft lengthy. The piles must be taken off. What is considered the most cost-effective way To accomplish this?
Micropiles are commonly made use of when you will find tough ground situations, for example normal or gentleman-manufactured obstructions, sensitive ground with adjacent buildings, minimal obtain/small headroom and/or karstic geology.
Micropiles may be used For brand spanking new construction applications in addition to for remedial repair of buildings. Micropiles are uniquely like minded for areas with constrained access and very low headroom Small diameter piles in which high load capacity is needed and conventional drilled shaft or driven pile installation is not feasible.
