ESTUDO DE CASO APLICADO À READEQUAÇÃO DE REDE DE DRENAGEM PLUVIAL

Abstract

In this case study we will see how the implementation of a new real estate development caused the collapse of the drainage system of an existing street on the site, due to the contribution of a new flow. The problem occurred in a 375.64m stretch and an average slope of 0.017m / m of Abraão Caineli Street, located in the Vargem neighborhood, in the city of Varginha-MG; during the installation of the residential neighborhood Treviso. Even though this project contemplated the referred road with a new drainage network, it proved to be deficient to the flow demanded in the event of heavy rains, necessitating the correction of its dimensions to avoid future problems; because the road in question is an important link between various neighborhoods of Varginha. Using concepts and calculations based on modern literature and well-known formulas such as the Intense Rain Equation (Rational Method); Manning Sizing Formula; We found the exact dimensions that would meet the demand flow and solve the problem.
