Abstract

Pour le percement de galeries souterraines en demi-section supérieure, on utilise un bouclier qui comprend une coque rigide 1 et une série de vérins de translation 3 et 12. La coque 1 est munie, le long de chacun de ses bords inférieurs, d'un sabot latéral 5 qui est relié à ce bord par des vérins 6 et le bouclier comprend, à l'écart de ce bord, au moins un pied 7 terminé vers le bas par une semelle 8 par rapport à laquelle la coque 1 est guidée par une glissière longitudinale 9. Application : percement de tunnels.
