Análisis experimental de la capacidad filtrante de drenaje de los agregados pétreos provenientes de la mina Los Moelles ubicada en la parroquia San Andrés, cantón Píllaro, provincia de Tungurahua

Abstract

Due to the diversity of voids, sizes and shapes, as well as the complex distribution of the soil, the flow of water through its mass is more complicated than through a tube or hole. To facilitate drainage, it is preferable to have a permeable soil. This study determined the physical properties of the soil, such as: Moisture Content, Atterberg Limits, and Granulometry. Using the AASHTO method, the soil is classified as Gravels and Silty or Clay Sands A-2-4 (0), while, by the SUCS method, soil samples 1, 3, and 4 are classified as poorly graded sand with silt with SP-SM gravel, sample 2 as poorly graded sand SP, and sample 5 as Poorly graded sand with SP-SM silt. For this purpose, a constant head drainage permeameter was used to determine the coefficient of permeability of the gravel, sand and silt of each sample. The results obtained indicate that the coarse aggregate has a high degree of permeability; the fine aggregate, a degree of medium permeability; and silt, a low degree of permeability. Finally, different combinations with different percentages of aggregates were carried out, concluding that the most efficient mixture contains coarse gravel, sand and fine gravel, with a medium degree of permeability, being within the range of permeable soils as established by the FAO.
