Cálculo de volumes de terra para controle de terraplenagem utilizando RPA e GNSS

Abstract

Earthwork is a very importante step for the execution of a construction and, frequently, it doesn’t receives the demanded attention, beign leaved on responsabillity of the workers that function the machines used for this job. In that way, many times this procedure is made without the proper care, occasioning constructive failures, patologies aparition and accidents. For obtain a high quality Earthwork, it it necessary a Project supported by topographic data form the terrain, obtained in a previous topographic survey, often denominated “Primitive”, made by a topography team. With the advance of the Technologies, the application of that in the execution of this surveys is beign studied in order to obtain products in smaller deadlines, using less resources and with na acceptable accuracy. Some Technologies that are been Applied are RPAs and GNSS Receivers, but, with more studies in land survey and planialtimetry and leaving by side other applications in civil enginering like Earthwork. This Course Conclusion Study has for objective the calculation of the Cut and Fill Volume movimented between two diferent dates on a land that is receiving a Earthwork, by computational reconstruction of the natural surface using data from aerophotogrammetrical surveys made by RPAs and GNSS Receivers. The results of this study shows that the aerophotogrammetrical survey can be used in calculation of the moved earth volumes, presenting a less costly and more agile alternative than the traditional topographic method.
