Pilotes inyectados y reinyectados con lechada cementicia a partir de columnas de grava excavadas.

Abstract

This thesis aims to conduct a bibliographical research on the use, theoretical principles and application of injected and reinjected piles. Likewise, a new structural element, focused on deep foundations for soft soils in the city of Guayaquil, is proposed, as well as a viable economic construction methodology for this structural element is presented. The proposed element is the injected and reinjected pile from excavated gravel columns, which is a combination of the aforementioned approach, where faster and cheaper materials and construction methods are used. The design of the cementitious grout and the optimal granulometry carried out in the laboratory would allow the former to achieve a resistance to work the pile efficiently by injection and reinjection at the tip not only by shaft, but also by tip, due to the root system obtained at the tip by reinjection.
