Pavimentos permeáveis no controle de cheias urbanas

Abstract

Nowadays floods have been one of the biggest problems of a significant number of Brazilian cities. This fact is related to the waterproofing of the soil, and the drainage model is not so efficient, due to this process value the speed of rainwater, this situation ends up overloading the whole system. To reverse this situation have been developed projects that seek a sustainable interaction with the environment, in this context the present study aims to understand how permeable pavements can be a solution to minimize flood cases and how it can be associated with the drainage system conventional. The methodology adopted to carry out this study will be the bibliographical review, in which will be analyzed literature dealing with urban drainage, permeable pavements and their types. Through the study carried out it is observed that the implantation of the permeable and feasible pavement in what concerns to avoid the overload of the drainage system of a city, nevertheless it is necessary to evaluate several factors in order to adapt the real needs of the environment in which it will be built is structure. Thus, the present study seeks to point out which are these factors that must be observed for the implantation of permeable pavements such as: type of pavement, slope, rainfall, construction method, cost benefit, soil type, vehicular traffic, drainage, water absorption.
