    • The known method for constructing a tunnel of the type that a shield tunnelling machine is shoved by means of a concrete lining jack and a shield jack equipped to the shield tunnelling machine with reaction forces received by concrete for lining placed in a space delimited by an inner form assembled within a tunnel bore successive­ly digged by the shield tunnelling machine, a shield tail and an already placed concrete lining, as well as by the inner form, is improved in order to construct a tunnel main body as a reinforced concrete structure. The improve­ments exist in that a reinforcing steel cage (13) is mounted to a combined spreader and end form (8a) of the concrete lining jack (8) via, the placed concrete for lining is com­pressed while the reinforcing steel cage is moved, and thereby the reinforcing steel cage is disposed at a pre­determined position within the concrete for lining.
    • 用于构造盾构隧道机的隧道的已知方法是通过混凝土衬套千斤顶和屏蔽隧道掘进机被施加的盾构通孔机,其中混凝土接收的反作用力被置于由内部限定的空间中 在由隧道掘进机连续挖掘的隧道孔内组装的形式,盾构尾部和已经放置的混凝土衬砌以及内部形式的结构被改进,以便构造作为钢筋混凝土结构的隧道主体。 改进之处在于,将钢筋保持架(13)安装到混凝土衬套(8)的组合式撒布机和端部形式(8a)上,在钢筋笼移动的同时,将衬砌的混凝土压实, 由此将钢筋保持架设置在用于衬里的混凝土内的预定位置。
