Uma análise comparativa entre os métodos executivos de fundação de estacas metálicas no complexo de Usinas Fotovoltaicas De Coremas - Pb

Abstract

The growing problem surrounding the generation of energy in a non-renewable way is a factor that makes it possible to advance in research and investments in alternative energy sources, to mention photo voltaic solar energy, which is acquiring more and more space and notoriety in the national territory, mainly due to presence of favorable geographical features. However, some aspects related to geotechnical investigations and execution techniques for the support foundations of solar modules are not yet standardized or fully understood, and mainly in the academic field, they lack foundation. In this perspective, this work aims to analyze the execution of three methods of metallic stake foundations, the micro pilot, the pre-drilling, and the direct drilling, used in the Complexo Solar Coremas - PB, with the premise of highlighting the most viable for the enterprise. For this, qualitative field research was carried out, with an exploratory objective, through the empirical observation of the process, the gathering of a documentary collection with pertinent information of the work, besides the accomplishment of an interview with the company executing the service, to remedy all the doubts arising from the realization of the foundation. Using the information and data collected, it was possible to carry out a comparison between the three methods that focused on costs, productivity, and time, so that it was verified that pre-drilling was the most viable executive method for the geological configuration of the area of study. Highlighting that this result was specific to the enterprise and was only possible due to the geotechnical investigation that occurred primarily, being essential to carry out such comparisons for future projects and areas of different geotechnical configurations.
