Abstract

Un estudio de entibación para la apertura de tuneles, galerías o tramos subterráneos y similares, consistente en un escudero precursor y un escudo seguidor montado detrás de él, estando el escudo precursor provisto de cuchillas precursoras apoyadas sobre un marco de apoyo precursor, y el escudo seguidor y pudiendo las cuchillas precursoras y seguidoras ser hechas avanzar a presión bien sea individualmente o bien por grupos, caracterizado porque el marco de apoyo precursor y el marco de apoyo seguidor pueden ser acoplados entre sí para formar una unidad cerrada, movible hacia delante, y al mismo tiempo pueden ser movidos hacia delante de manera independiente uno del otro al estar en estado desacoplado, por medio de un dispositivo de avance intercalado entre ellos.
