Drenagem de águas pluviais : estudo de caso de um trecho de uma rua movimentada da capital mineira na Região Noroeste

Abstract

The present study presented a case report of an emergency work that was carried out in September 2021 on Rua Vila Rica, Northwest Region of the capital of Minas Gerais. Before, the conventional rainwater drainage system adopted was concrete pipes, but due to flooding that occurred in the place, it was replaced by HDPE pipes as a non-conventional system, that is, one that does not fit the conventional system, adopted by SUDECAP. This site's drainage system plays a key role in preventing urban flooding. Given this scenario, the present study has the general objective of comparing the two types of rainwater drainage related to the conventional system using concrete pipes and the unconventional system using HDPE pipes, using as a basis the case study of a section of a busy street in the capital of Minas Gerais in the Northwest Region. The present study was an in loco case study, it was an empirical way of investigating the current phenomenon within its real context, with a triangulation of analysis methods being carried out. This triangulation included a documentary investigation and surveys of perceptions through on-site visits with observation. After contextualizing the operation of an entire rainwater drainage system, explaining the components, their functions and characteristics, the importance of each part and the interdependence between them can be perceived, as well as understanding the reason for replacing concrete and HDPE pipes in the work in question. It is concluded, therefore, that the use of HDPE pipes provides better advantages compared to concrete pipes, such as high durability, non-leakage, high degree of efficiency, among others.
