COMPARATIVO ECONÔMICO ENTRE SOLUÇÕES CONSTRUTIVAS PARA RECUPERAÇÃO DA ÁREA DE IMPLANTAÇÃO DE UMA REDE INTERCEPTORA DE ESGOTOS SANITÁRIOS: estudo de caso

Abstract

The objective of this work is the economic comparison between two constructive alternatives to recover the area of ​​implementation of a sewage interceptor network. The first using gabions to contain erosion-damaged soil. Later, one has the option of the soil containment technique, using bagged cement soil, popularly known as rip-rap. The projects were developed through hydrological analysis for stream characterization and soil characterization that make up the interceptor network area. They love each other for two alternatives, containment height at 4 meters and base at 3 meters. Soil retention structures were chosen to protect the damaged network along two specific sections, since the proximity of the network to the stream has been potentiating the problem under study. In addition, by carrying out the analyzes and comparisons, we obtained the best alternative to the desired financial situation, as seen from the gabion wall. The result for comparisons was obtained by estimating budget of the entire length of the walls, being 284 linear meters.
