Resumo: | In 2010, the Dam Safety Law was enacted, which aims to implement a culture of predictive and preventive maintenance in Brazilian dams. This article aims to describe the main pathological manifestations in the Jucazinho Dam and its possible treatments. The methodology involves: a literature review; the characterization of the Jucazinho dam; compilation of anomalies identified in the bus body; and proposing techniques for recovery. Through the report of the consultancy contracted by the Department of National Works Against Drought (DNOCS), the following anomalies in the structure were identified: presence of bladders in the main spillway, where the treatment will be given by the application of a high-strength mortar; damage to the structure of the dissipation basin, where a ski jump will be built at the end of the main overflow; cracks and cracks observed along the dam that will be treated with injection of polyurethane resin; and deposition of fine material in addition to infiltration into the gallery, which will be corrected with mortar injection every 3.0 m along the dam to the rock layer. At the end of this article, it is evident that there is a need to adopt a system of safety inspections to identify possible pathological manifestations prematurely. |

Case study: Diagnosis and actions of structural recovery of the Jucazinho/PEEstudo de Caso: Diagnóstico e Ações de Recuperação Estrutural da Barragem de Jucazinho/PEIn 2010, the Dam Safety Law was enacted, which aims to implement a culture of predictive and preventive maintenance in Brazilian dams. This article aims to describe the main pathological manifestations in the Jucazinho Dam and its possible treatments. The methodology involves: a literature review; the characterization of the Jucazinho dam; compilation of anomalies identified in the bus body; and proposing techniques for recovery. Through the report of the consultancy contracted by the Department of National Works Against Drought (DNOCS), the following anomalies in the structure were identified: presence of bladders in the main spillway, where the treatment will be given by the application of a high-strength mortar; damage to the structure of the dissipation basin, where a ski jump will be built at the end of the main overflow; cracks and cracks observed along the dam that will be treated with injection of polyurethane resin; and deposition of fine material in addition to infiltration into the gallery, which will be corrected with mortar injection every 3.0 m along the dam to the rock layer.

Em 2010 foi promulgada a Lei de Segurança de Barragens que tem dentre seus objetivos implementar uma cultura de manutenção preditiva e preventiva nas barragens brasileiras. Este artigo visa descrever as principais manifestações patológicas na Barragem de Jucazinho e seus possíveis tratamentos. A metodologia envolve: a revisão da literatura; a caracterização da barragem de Jucazinho; a compilação das anomalias identificadas no corpo do barramento; e a proposição de técnicas para recuperação. Através do relatório da consultoria contratada pelo Departamento de Nacional de Obras Contra as Secas (DNOCS) foram identificadas as seguintes anomalias na estrutura: presença de bexigas no extravasor principal, onde o tratamento dar-se-á pela aplicação de uma argamassa de alta resistência; danos na estrutura da bacia de dissipação, onde será construído um salto em esqui ao final do extravasor principal; fissuras e trincas observadas ao longo do barramento que serão tratadas com injeção de resina poliuretânica; e deposição de material fino além de infiltração na galeria, que serão corrigidas com injeção de argamassa a cada 3,0 m ao longo do barramento até o estrato rochoso. Ao final deste artigo, fica evidente a necessidade de adoção de uma sistemática de inspeções de segurança para identificar prematuramente possíveis manifestações patológicas.Escola Politécnica de Pernambuco2021-09-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttp://revistas.poli.br/index.php/repa/article/view/168210.25286/repa.v6i4.1682Journal of Engineering and Applied Research; Vol 6 No 4 (2021): Revista de Engenharia e Pesquisa Aplicada; 46-53Revista de Engenharia e Pesquisa Aplicada; v. 6 n. 4 (2021): Revista de Engenharia e Pesquisa Aplicada; 46-532525-425110.25286/repa.v6i4reponame:Revista de Engenharia e Pesquisa Aplicadainstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPEporhttp://revistas.poli.br/index.php/repa/article/view/1682/755http://revistas.poli.br/index.php/repa/article/view/1682/756-Copyright (c) 2021 Joao Batista de Limahttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessde Lima, Joao Batista2021-09-09T11:48:44Zoai:ojs.poli.br:article/1682Revistahttp://revistas.poli.br/index.php/repaONGhttp://revistas.poli.br/index.php/repa/oai||repa@poli.br2525-42512525-4251opendoar:2021-09-09T11:48:44Revista de Engenharia e Pesquisa Aplicada - Universidade Federal de Pernambuco (UFPE)false |
