Abstract

FUNDO DUPLO EM CAMARA DE INSPEçãO. A presente invenção de fundo duplo para câmara de inspeção é compreendida por um primeiro fundo 2 que é a parede inferior das canaletas 3 que direcionam o fluxo e um segundo fundo 8, nervurado 9, um pouco abaixo, separado por uma projeção cilíndrica 6, também provida com nervuras 7. O espaço vazio 4 entre o primeiro e segundo fundos 2 e 8, prevê ainda opcionalmente um enchimento para melhorar as propriedades de resistência à compressão, introduzindo-se algum material solidificável 10, seja material expansível ou concreto, que podem inclusive ser reforçados com algum material de carga.DOUBLE BACKGROUND IN INSPECTION CAMARA. The present double bottom inspection chamber invention is comprised of a first bottom 2 which is the bottom wall of the flow direction channels 3 and a second ribbed bottom 8 slightly below separated by a cylindrical projection 6 also 7. The void 4 between the first and second bottoms 2 and 8 optionally further provides a filler to improve the compressive strength properties by introducing some solidifiable material 10, either expandable or concrete, which may even include be reinforced with some load material.
