Abstract

1,153,454. Tunnelling machines. MEKHANICHESKY ZAVOD No. 5. 30 Sept., 1966 No. 43747/66. Heading E1F. The front of the boring head of a tunnelling shield comprises two or more unilinear, preferably helical, excavating blades 4, 5. Each blade has a radially extending, cutter carrying, leading digger edge 6 in the rotary sense of the motion of the head, the edge 6 being ahead in the sense of the direction of advance of the machine of the trailing edge 7 of the preceding blade in the rotational sense. The trailing edges 7 are provided with breaker bits.
