PROPOSTA DE READEQUAÇÃO DO SISTEMA DE DRENAGEM NO QUILÔMETRO 29,1 DA RODOVIA MG-167

Abstract

This work analyzes the transplant drainage problems of kilometer 29.1 of the Três Pontas / Entr ° BR-491 A section (Varginha) of the MG-167 highway. The purpose of this study is to diagnose the drainage problems that caused erosion on a grove culvert, characterized as BSTM. This attempt will be achieved through bibliographical research, hydrological data collection for characterization of the contribution basin, on-site visits for data acquisition and consultation at the agency responsible for the highway. Once the flow of the contribution basin was calculated, it was compared to the capacity of the already existing culvert. The analysis showed that the flow of the contribution basin is greater than the flow that the drainage is able to carry, which showed that it was not designed to support all the flow of the basin alone, however with the analysis of the other sewers in project and currently all without hydraulic function, it is proved that the manhole studied was not poorly sized, but with the degradation of the others, it was overloaded, being located at the lowest point of the river basin. Therefore, it was understood that the best way to re-adjust the drainage system of the site would be to replace the existing sewer with another capable of transporting all the flow of the basin. It was proposed the implementation of a BSCC and its dimensioning, as well as the design of the same. Once this new system was scaled, it was estimated that the cost for its implementation would be R$398.857,21.
