Dimensionamento hidráulico de redes coletoras de esgoto sanitário usando o critério de atendimento crítico

Abstract

Sewage systems are important elements to ensure the health and social welfare, however, elaborating projects to develop these structures involves activities with very onerous and repetitive steps. Thus, with the objective to reduce the time spent, ensuring quality and efficiency of the final project, computer programs have been gaining space and importance in engineering projects. The program UFC9 is an application developed in languages AutoLISP, VBA (Visual Basic for Applications)and VB (Visual Basic), which has graphics resources to assist in developing projects within the AutoCAD environment. This work was developed to assist in developing projects of sewage systems in the elements related to design, sizing, quantification and budget for these important elements of a sanitary sewage system. In the case of drawings, this software helps in tracing the collection network and profiling, in the case of dimensioning, the software allows the network dimensioning considering or not the critical coverage, in which they are located houses below the pipes. Another important consideration is the possibility of setting obstacles in the network, thus avoiding problems during the execution of the work. The dimensioning worksheets and budget generated by the program can be exported to Excel, facilitating the development of descriptive memorials and calculations, and allow for changes or additions in the budgets of networks generated by the software.
