Abstract

Perfeccionamientos en escudos de cuchillas de perforación para abrir túneles, galerías y otras cavidades subterráneas, apuntables contra la pared del huevo y prensables hacia delante mediante prensas, que forman una envuelta de escudo que asegura el espacio del hueco, caracterizados porque cada escudo están que se acoplan a modo de una barra de acoplamiento, de tal manera que el apuntalarse una de las cuchillas de perforación contra la pared del hueco la cuchilla de perforación opuesta se mete forzosamente en sentido contrario.
