Abstract

1,165,815. Tunnelling. KUMAGAI GUMIK.K. 21 July, 1967 [29 July, 1966; 29 Aug., 1966; 31 Dec., 1966 (2); 7 Feb., 1967], No. 33627/67. Heading E1F. Tunnelling apparatus comprises a shield 1 (Fig. 1) moved by jacks 3, and a cutter 5 moved relatively to the shield by further jacks 6. To prevent earth passing inwardly between the cutter and the shield they are connected by a rubber ring 9, or a sleeve attached to the outer slides over the shield. As shown in Fig. 7 the shield may carry vertical cutters 19, and one or more horizontal cutters 15 moved relatively to the shield by jacks 18. Figs. 11, 13 show shields 1 of non circular cross section carrying cutters 5.
