Desenvolvimento de um projeto com dispositivos modulares para um reservatório de amortecimento de pico

Abstract

The disordered growth of urban regions, mainly caused by the rural exodus of the 1970s and 1980s, has the consequence of expanding the impermeable areas of the soil, leading to an increase surface flow off. The drainage solutions most used today are based on the idea of transporting rainwater to places far from urban centers, which ends up generating floods in regions that previously didn’t had this events. One of the solutions to this problem is the amortization of rain volumes in order to avoid major peaks of floods. The city of Curitiba, has the decree 1733/2020, which covers matters related to the mandatory use of flood containment mechanisms according to the built and waterproofed terrain area. In this research, a peak damping reservoir project is developed obtained from the union of pre-designed standard modules for regions up to a thousand square meters. Through a division according to the impermeable area of the land, the characteristics of the reservoirs are obtained. The determination of the internal dimensions of the reservoir was obtained through the information contained in decree 1733/2020. The thickness of the plates that make up the walls and slabs of the reservoirs were obtained through the structural calculation, where the actions of selfweight, overload, hydrostatic pressure and ground pressure were considered. Therefore, it is possible to determine a peak damping reservoir only with information regarding the impermeable area of the terrain in an easier way, enabling greater adherence to this type of solution that contributes to the better operation of the urban drainage system.
