Abstract
Un escudo porta-cuchillas para perforar un túnel, abrir una galería o cualquier otra cavidad en la tierra o la roca, cuyas cuchillas perforadoras, que forman el escudo, están sustentadas sobre un bastidor de apoyo común y pueden ser hechas avanzar a presión por medio de prensas hidráulicas, que consisten en mecanismos de émbolos hidráulicos situados en el interior de las cuchillas perforadoras y que se apoyan contra el bastidor de apoyo, caracterizado porque, en su extremo posterior, el bastidor de apoyo (10) presenta piezas de empalme (31) para el empalme de los mecanismos (17) de émbolos hidráulicos, los cuales, bajo hermetización (23, 24) están sacados por detrás hacia fuera de los espacios interiores (16) de las cuchillas perforadoras (11) y, por detrás de la junta, están acoplados a las piezas de empalme(31) del bastidor de apoyo (10).
