Abstract

''DISPOSITIVO DE DESMONTE PARA CONEXãO A UMA FONTE DE GáS COMPRIMIDO, E, PROCESSO DE DESMONTE''. Um dispositvo de demolição a ar-comprimido (1), inserível em um foro previamente preparado, tem um alojamento cilíndrico ou tubo (2) contendo um número de canhões de ar (4). Orifícios (3) no alojamento (2) direcionam o fluxo de ar-comprimido descarregado pelos canhões de ar (4) de modo a produzir um acúmulo de pressão suficiente para enfraquecer e deslocar o material da área ao redor do furo. Para realçar ainda mais o efeito do dispositivo (1), o furo pode ser preenchido com água e selado com um obturador
