    • Bei einer Schildvortriebseinrichtung (1) ist vorgesehen, zwischen einer eine Förderschnecke (5) aufweisenden Abfördervorrichtung (4) eine Ausschleusvorrichtung (10) mit einer Drosseleinheit (9) vorzusehen, die über wenigstens ein Paar einander gegenüberliegender Walzen (13, 14) verfügt. Die Walzen (13, 14) sind jeweils paarweise gegenläufig drehbar, wobei die jeweilige Drehrichtung der Walzen (13, 14) in ihrem aufeinander zu weisenden Bereich von der Abfördervorrichtung (4) wegweist. Die gegenläufigen Walzen (13, 14) fördern aufgrund der Sog- und Transportwirkung sowohl stark schluffhaltiges Material als auch einen hohen Anteil an Grobfraktion aufweisendes Material, ohne dass ein Wechsel in der Betriebsart oder die Beigabe von Zusätzen erfolgen muß.

    • A shield tunneling machine comprises a shield body (1). The shield body is divided into a soil chamber (8) and an inside chamber (9) by a partition wall (7). The soil chamber (8) has a conical peripheral surface converging gradually rearward. A crankshaft (18) having an eccentric portion is rotatably supported by the partition wall (7) at the center of the partition wall corresponding to the axis of the shield body. A cutter disc (3) with roller bits is secured to a front end of the crankshaft, and a conical rotor (20) is rotatably mounted on the eccentric portion of the crankshaft behind the cutter disc . A rear end of the crankshaft is connected with a drive. Since the cutter disc is rotated at an increased rotary velocity by five to ten times as many as that of a cutter disc in a conventional shield tunneling machine, crushing of gravels can be efficiently carried out by the cutter disc with roller bits in coorporation with the conical rotor mounted on the krankshaft.
    • 盾构隧道机包括屏蔽体(1)。 屏蔽体通过分隔壁(7)分为土壤室(8)和内室(9)。 土壤室(8)具有逐渐向后收敛的圆锥形周向表面。 具有偏心部的曲轴(18)在分隔壁的与屏蔽体的轴线对应的中心处由分隔壁(7)可旋转地支撑。 具有滚子钻头的切割盘(3)固定到曲轴的前端,并且锥形转子(20)可旋转地安装在切割盘后面的曲轴的偏心部分上。 曲轴的后端与驱动器连接。 由于在传统的屏蔽隧道机中刀盘的旋转速度提高了5至10倍,因此可以通过切割盘有效地进行砾石的破碎,该切割盘与滚筒钻头 锥形转子安装在曲轴上。
