Abstract

L'invention concerne une paroi souterraine fabriquée, constituée par l'épissage de multiples parois (1). La paroi (1) est formée par assemblage d'une paroi inférieure (1-1) et d'une paroi supérieure (1-2) ; un sous-orifice concave-convexe d'une structure en acier est disposé au niveau du joint d'épissage de deux parois adjacentes (1), c'est-à-dire qu'une saillie sur l'une des parois est incorporée dans un évidement sur l'autre des parois ; les surfaces inférieure et latérales des parois (1) sont pourvues de chenilles (2) ; un dispositif de coupe à chaîne (3) est monté sur la chenille (2) pendant la construction ; le dispositif de coupe à chaîne (3) est composé d'une chaîne (3-1) et d'un dispositif de coupe (3-2) monté sur la chaîne (3-1) ; pendant la construction, le dispositif de coupe à chaîne (3) excave simplement de la roche au fond de la paroi (1) ; la paroi (1) et le dispositif de coupe à chaîne inférieur (3) se déplacent vers le bas simultanément ; une fois qu'un plan supérieur d'une paroi inférieure (1) est abaissé avec le dispositif de coupe à chaîne jusqu'à une hauteur définie par rapport au sol, la paroi supérieure (1-2) est assemblée et épissée ; et le soudage est effectué au niveau du joint entre les parois supérieure et inférieure avant que les parois ne soient envoyées sous terre, ce qui permet d'intégrer les parois dans un ensemble. L'invention concerne également un procédé de construction de la paroi souterraine fabriquée.
