"OVERVIEW ON IMPROVING BEARING CAPACITY OF SOIL USING GROUND IMPROVEMENT TECHNIQUE MICROPILES”

Abstract

Micro piles are used in many applications of ground improvement technique to increase the bearing capacity and reduce the settlements and strengthening of the foundations. Advantages of Micro piles are fast one step installation, simultaneous drilling and grouting, allows the use of smaller equipment at lower cost, allows low overhead, limited access installation, improves the ground (densification), offer higher skin friction, total single corrosion protection by design. This piling system is most economical to both the client and foundation Engineer. Micro pile installations can perforate to hundreds of feet in depth and also each of the piles can support tons of load. This paper deals with a review on Micro pile technology which is a reliable pile system that can withstand large capacity axial or lateral loads with minimum interference to the existing structures. Micro piles became most popular due to their capacity to carry loads efficiently through skin friction and also their installations advantages over conventional pile system. Micro piles have the potential of consolidate micro pile technology with one or more of the other ground improvement techniques to meet distinctive or complex project requirements economically and efficient.
