Análisis experimental de la capacidad filtrante de drenaje de agregados pétreos provenientes de la cantera Playa Llagchoa y/o salvador, ubicada en el km7 vía a Aguaján, parroquia Santa Rosa, provincia de Tungurahua

Abstract

In the field of civil engineering, the filtering capacity of stone materials is of vital importance for the design and construction of efficient drainage works. The experimental work focused on investigating the permeability of the aggregates from the Llagchoa/Salvador Beach Quarry, located in the Tungurahua province. A survey of documentary information on the quarry was carried out and representative samples were collected for laboratory tests. Different tests were carried out to evaluate the physical properties, such as moisture content, Atterberg limits and granulometric analysis. Subsequently, by using a drainage permeameter with the constant head method, the permeability coefficient of each type of soil (gravel, sand, and silt) was obtained. The results indicated that the aggregates had a medium to high filtration capacity, with silt having the lowest permeability. Finally, the optimal drainage combination was sought, to estimate the filtration capacity of the soil, resulting in the most appropriate with a permeability coefficient of 4.06x10 raised to at least 2 (m/s) being the same permeable which makes it suitable for use in civil engineering projects related to drainage. This study provides valuable information for the design and construction of effective drainage systems, thus contributing to the development of more resistant and sustainable infrastructures, being useful for professionals in the field of engineering and for those interested in improving water management in civil works.
