Abstract

APARATO PARA INSTALAR UMA ENSECADEIRA EM UM LADO ÚMIDO DE UMA PAREDE SUBMERSA, INSTALAÇÃO, E MÉTODO DE INSTALAÇÃO DE UMA ENSECADEIRA. Uma ensecadeira 110 é guiada e instalada contra uma parede submersa 2 de uma estrutura 1 por um ou mais cabos flexíveis 50. Cada cabo é retraído, por meio de uma abertura 7 formada na parede 2, por um puxador de cabo 20 montado dentro de um espaço interno 4 da estrutura 1 para empurrar a ensecadeira contra a parede 2. Um corpo de conexão 10 é fixado de forma vedável ao lado seco 6 da parede 2 para envolver a abertura 7, e uma barreira de pressão 21 é conectada de forma vedável ao corpo de conexão 10 para excluir água do espaço interno 4 durante o funcionamento do puxador de cabo 20. O puxador de cabo 20 pode ser configurado como um conjunto de guincho com uma formação de invólucro da barreira de pressão 21Apparatus for installing a cofferdam on a wet side of a submerged wall, installation and method of installing a cofferdam. A cofferdam 110 is guided and installed against a submerged wall 2 of a structure 1 by one or more flexible cables 50. Each cable is retracted, through an opening 7 formed in the wall 2, by a cable puller 20 mounted inside a inner space 4 of the frame 1 to push the cofferdam against the wall 2. A connecting body 10 is sealably attached to the dry side 6 of the wall 2 to surround the opening 7, and a pressure barrier 21 is sealably connected to the connecting body 10 for excluding water from the internal space 4 during operation of the cable puller 20. The cable puller 20 can be configured as a winch assembly with a pressure barrier casing formation 21
