A construtora OAS necessitava de uma solu\u00e7\u00e3o eficiente para evitar a flutuabilidade de dutos em \u00e1reas alag\u00e1veis no projeto \u201cEmiss\u00e1rio de Efluentes\u201d do Complexo Petroqu\u00edmico do Rio de Janeiro (COMPERJ). A t\u00e9cnica convencional indicada nestes casos \u00e9 caracterizada pelo lastreamento dos dutos com a utiliza\u00e7\u00e3o de jaquetas de concreto, armadas com telas eletrosoldadas de a\u00e7o. Devido ao curto cronograma da obra, seria fundamental que o processo de concretagem das jaquetas fosse feito num tempo inferior ao processo convencional em telas.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Atrav\u00e9s da parceria formada pela OAS, COPPE-UFRJ e Maccaferri, foram realizados testes supervisionados pela Petrobr\u00e1s, que comprovaram a efici\u00eancia do uso das fibras met\u00e1licas Wirand\u00ae FF4 como elemento de refor\u00e7o estrutural para a constru\u00e7\u00e3o das jaquetas de concreto. A utiliza\u00e7\u00e3o das fibras na dosagem 30 kg\/m\u00b3,em substitui\u00e7\u00e3o \u00e0s telas eletrosoldadas, resultou em um consider\u00e1vel ganho de produtividade no processo executivo das jaquetas, al\u00e9m de atender as exig\u00eancias de qualidade da obra.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>","protected":false},"excerpt":{"rendered":"
