Enhancement of Open-Ended Pipe Pile Embedded in Sand Using Steel Collar

The open-ended pipe piles are among the that employed most frequently because of their advantages, including ease transport and resistance to driving stress. It is further distinguished by fact soil column formed inside pile increases capacity. Numerous ideas have been presented forth in literature enhance performance these piles. In this study, it suggested a steel collar be used at its lowest end pile. Ten experimental tests for embedded loose sand were carried out determine impact diameter length concerning length. Three diameters, 1.5D, 2D, 3D, three ratios: 10, 20, 30% employed. use improves load capacity reduces settlement, according data, although with 1.5D 10% had little effect. According using 2D 20% enough double prevent overlapping effect stress bulbs between neighboring As result, such method minimizes cost constructing foundations reduction number required.
