Abstract

W czasie przepychania tunelu (1) pokrywa się jego górną powierzchnię dolną blachą (6), rozwijając ją z tylnego bębna (2). Koniec tej dolnej blachy (2) mocowany jest do tunelu od strony urabiającej głowicy (7). Cięty grunt (5) pokrywa się natomiast nad tunelem (1) górną blachą (9), rozwijaną z przedniego bębna (3). Koniec tej blachy (9) związany jest z konstrukcją (4), znajdującą się przed gruntem (5). W miarę cięcia gruntu (5) urabiającą głowicą (7), dolną blachę rozwija się z tylnego bębna (2), przesuwając ją wraz z tunelem (1) po dolnej powierzchni górnej blachy (9), rozwijanej z przedniego bębna (3). Po przepchnięciu tunelu (1), bębny (2, 3) demontuje się.When pushing the tunnel (1), its upper surface is covered with the bottom sheet (6), unrolling it from the rear drum (2). The end of this bottom sheet (2) is attached to the tunnel from the cutting head (7). The cut soil (5) covers the tunnel (1) with the upper plate (9), unrolled from the front drum (3). The end of this plate (9) is connected to the structure (4) in front of the ground (5). As the soil (5) is cut with the cutting head (7), the lower plate develops from the rear drum (2), moving it together with the tunnel (1) on the lower surface of the upper sheet (9), unrolled from the front drum (3). After pushing the tunnel (1), the drums (2, 3) are disassembled.
