Micro Piling for Retrofitting of Structures-Case Studies

Mahipal Burdak ^[6] | Amita ^[79]

Abstract: Piles are used to transfer the load of the super structure to the hard bearing strata below ground surface. To resist the horizontal load, for work over water eg. Jetties or bridge piers, a soil is not having adequate bearing capacity pile foundation is beneficial. In some difficult geotechnical condition instead of piles, Micro piles are very useful. They are used due to its flexibility and ductility in seismic condition. Micro piles are drilled, having a diameter less than 300mm. They are grouted by neat cement grout. They also increase the bearing capacity and reduce the settlement of the soil. Many historical structures which are not built according to code and the structures and which are damaged during earthquake need to retrofit. For seismic retrofitting of the structure and underpinning works Micro piles are very much useful.
