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