Foundation Reinforcement with Inclined Corrugated Micro-Piles: A Practical Perspective
Year: 2025
Type: article
Abstract: Micro-pile is a type of pile which acts as a supporting structure to transfer the load from building to the ground. Micro-pile is a deepfoundation element constructed using high strength, small diameter steel casing or corrugated bar. By using corrugated bars high bondstrength will be developed.The soil chosen for this study is Chenkal clay and the geotechnical properties of the soil were determined. Fe 500TMT corrugated bars (micro-piles) of 12 mm diameter (D) were purchased for the study and cut to lengths 5D, 10D & 12.5D. The micro-pileswere provided at spacing’s 2D, 3D & 4D. Inclinations adopted for the study were 15°, 30° & 45°. Square footing in a square pattern andcircular footing in a triangular pattern were adopted. The plate load tests were conducted on both square & circular footing.The bearingcapacity of soil and settlement of foundation were determined on both square & circular footing and shows a percentage increase of 15.79% &percentage decrease of 62.97% respectively for square footing & a percentage increase of 14.85% & percentage decrease of 56.25%respectively for circular footing. The optimum length, spacing and inclinations were determined on square footing and circular footingrespectively. Comparison study on square footing and circular footing were done.
