O estudo do método não destrutivo HDD como alternativa à abertura de valas para implementação de linha de esgoto em Recife, PE

Abstract

The need to deploy underground pipelines for access to primary public services for the population can cause social disruption in view of its traditional executive method. The opening of trenches affects the population, due to its invasive aspect of execution, and generates disturbances to the routine in society due to its impact on traffic dynamics. Its slow construction development, coupled with the other consequences, leads engineering to search for new implementation technologies. Non-destructive methods present themselves as an alternative to the disturbances of not interrupting the surface for underground procedures. In this context, the present work studies the design of a sanitary sewage discharge line, which will be executed in light of part of the historical site of Recife, Pernambuco, by the non-destructive method of horizontal directional drilling (HDD). A direct cost comparison was made between the destructive and non-destructive methodology. The survey of the social cost at peak hours was raised, burdened by traffic disturbed by a hypothetical trench opening, so that there is an opinion regarding the economic viability of the execution chosen by the company
