Modelación hidráulica para la determinación de la eficiencia de los sumideros tipo T45 modificado con barrotes longitudinales de aguas lluvias

Abstract

The main objective of this project is to determine the efficiency of storm drain inlets located on urban roads – our proposed curb inlets were designed with an alternate geometry to the conventional models and complying with the parameters established in current regulations of Ecuador. The experimental platform of the curb inlet frames symbolizes a half way at 1: 4 scale representing the geometric, kinematic and dynamic similarity of the hydraulic model. The model was built at the Laboratory of Hydraulics of the Faculty of Civil and Mechanical Engineering using acrylic as the main material. Several scenarios of curb inlets with longitudinal bars distributed in different positions were studied. Additionally, different rain water flows were considered by combining the longitudinal slope of 2-4 percent and the transverse slope of 0.5-4-8-12 percent. The experimental study was developed in two phases; Phase I includes the location of the curb inlets with a 0.00 level, reaching the maximum efficiency of 84 percent with four curb inlets with a longitudinal and transverse slope of 0.5 and (2-4) respectively. Phase II examines the curb drains with a level + 1.75cm above the level of the road, obtaining the highest efficiency of 75 percent with four curb inlets (drains), combining the longitudinal and transverse slope of 12 and 2 percent respectively.
