MICRODRENAGEM: ESTUDO DE CASO DA RUA DOUTOR JOSÉ BÍSCARO NO MUNICÍPIO DE VARGINHA – MG

Abstract

The microdrainage system has the function of collecting and conducting rainwater up to the macro drainage system, as well as removing rainwater from the pavements of public roads, avoiding floods, offering safety to pedestrians and drivers and avoiding or reducing damages. It occupies a prominent place among the hydraulic and sanitary works, fundamental in the planning of the cities, being part of the set of public improvements existing in an urban area. Unfortunately in most cities in Brazil, it is the least considered, noted during the execution of this work, in Rua José Bíscaro, located in the city of Varginha - MG, where in times of heavy rains it has deficiencies related to the drainage system Urban The biggest problem is the formation of floodwaters, directly affecting the population, either with financial losses or even disease spread. For this situation, the present study had as motivation the survey, characterization and analysis of the factors that directly influence the drainage conditions of this region, highlighting the rainfall intensity, return period, concentration time, surface runoff coefficient and conditions Of the physical mechanisms of drainage (gutters, lobes, galleries and wells), which are mostly deficient. In addition to being undersized and not meeting the requested flows, their utilization capacities are substantially reduced due to lack of periodic repairs or maintenance. After characterizing and surveying the evidence that the current drainage system does not effectively meet its demands in times of heavy rains, a new project was generated in this study, ie a complementation for the existing elements in the basin, with the Installation of new pipes, mouths of wolves, gutters and wells, in order to have a new system that meets the flow demand generated by the basin.
