The rebar cage is the same as the cage Employed in common piling. Threaded couplers are used to be a part of the bars together with staggered joints. A centraliser (According to fig) is useful for positioning the rebar cage In the bore.
A foundation is called piled when its depth is much more than 3 times its breadth. Micropiles are piles that have a comparatively tiny diameter, typically during the array of 100-250 mm. They can also be called Minipiles (typically mini piles are lesser than micro piles)

Keller can Incorporate our micropile technology with one or more of our other ground modification strategies to meet distinctive or complicated venture specifications cost-correctly and competently. Strains of micropiles spanned by wood lagging could be perfect the place excavation partitions are demanded in very low headroom together with other confined regions.
Grouting: The casing is crammed with significant-power grout to protected it in place, making sure balance and reinforcing the pile’s strength.
In larger micropile patterns, casing diameter is minimized because the effective Web place accessible for reinforcement is optimized with just one larger bar vs . lesser bundled bars (see illustration).
Reinforcing metal, usually an all-thread bar is inserted in the casing. Large-toughness cement grout is then pumped in to the casing. The casing could increase to the total depth or end previously mentioned the bond zone, Using the reinforcing bar extending to the total depth.
