Propuesta de diseño de escombrera de residuos de construcción para el GAD municipal del cantón Morona, provincia de Morona Santiago

Abstract

This project mainly aimed to develop a design of a dump for construction waste, specifically for the Autonomous Decentralized Municipal Government of Morona canton in the province of Morona Santiago. To achieve this objective, several stages were carried out using CivilCAD 3D software. At first, an SPT test was carried out to evaluate the load capacity of the soil. Then, tools such as ArcGIS, AutoCAD and CivilCAD 3D were used to analyze the topography, morphology, geology, hydrology and other crucial parameters that contributed to define an adequate design for the dump. In addition, soil classification tests, determination of natural moisture content, specific gravity and sieve grain size analysis were carried out. These data were essential to calculate the volume required for stockpiling in the dump, as well as to determine the volumes corresponding to the stripping and subbase material. Based on all the information gathered, it was proposed a dump design that meets the requirements for the controlled disposal of construction waste. The design includes two benches, safety berms, trapezoidal ditches for surface drainage along each bench, an internal subdrainage network, and a geomembrane subbase to guarantee a 50-year lifespan. This approach efficiently responds to the city's current construction waste collection needs and thus avoids the collapse of the canton's landfill.
