1 ESTACAS-PRANCHA SINTÉTICAS Vitor José Rodrigues Engenheiro Civil

2 Introdução à CMI Ltd. Introdução às Estacas-prancha Crane Aplicações das Estacas-prancha Crane Agenda Caso de Obra Corredor Portuário de Barranquilla Equipamentos e Rendimentos de Instalação Passarelas GATOR

3 CMI 60 anos de experiência no desenvolvimento de produtos de PVC; Criador das estacas-prancha vinílicas; Conta com 18 patentes e 40 anos de desenvolvimento de estacas-prancha em conjunto com o Corpo de Engenheiros do Exército Norte Americano (United States Corps of Engineers - USACE).

4 O que são estacas-prancha? As estacas-prancha são longos perfis produzidos em PVC, PRFV (compósito), alumínio ou aço, que, quando encaixados, justapostos e cravados no solo, compõe uma cortina. Tipicamente, são corrugadas, em forma de Z ou U,

5 O que é uma estaca-prancha? sendo que duas estacas de seção em Z formam uma seção em U. Encaixe macho-fêmea

6 Painel plano (FP)

7 Aplicações Temporárias Escoramento de vala Fundação Estrutura para estacionamento subterrâneo Permenantes Estabilização de taludes Muros de contenção Proteção de bordas costeiras Estabilização de rodovias Revestimento de canais Estabilização de leitos de rios Barreira contra enchentes / sistemas de retenção/detenção Cortinas impermeabilizantes Barreira contra contaminantes

8 O que é uma estaca-prancha? São fabricadas em: q q q q q q Aço laminado a quente; Aço conformado a frio; Concreto armado; Madeira tratada; Cloreto de Polivinila (PVC): q ; Resina de Poliéster Reforçada com Fibra de Vidro (PRFV): q ; q Alumínio: q.

9 Cloreto de Polivinila (PVC): Até 4,0m de altura livre Resina de Poliéster Reforçada com Fibra de Vidro (PRFV) Até 7,0m de altura livre

10 Estacas-prancha Crane Materials International q 35 Anos de Experiência Pioneiros na fabricação q Durabilidade Garantia de 50 anos; não sofre corrosão; livre de manutenção q Resistência Não sofre ataque química provocado por compostos químicos corrosivos; resistência aos raios UV q Peso Reduzido Facilita a manipulação q Produto Ecológico e Sustentável Fabricado com 80% de material reciclado e 100% reciclável q Custo Competitivo Custo do material competitivo e baixos custos com transporte e instalação q Tecnología XCR Co-Extrusão de Alta Precisão q Instalação Facilidade e rapidez até 50 metros lineares por día

11 Projetos Muro ancorado: Ex.: Proteção contra Erosão Muro em balanço (Cantilever): Ex.: Detenção de Água
