Abstract

1452751 Boring earth SUMITOMO METAL MINING CO Ltd 12 Oct 1973 [16 Oct 1972 20 Nov 1972 28 July 1973 8 Aug 1973 10 Aug 1973 21 Aug 1973] 47792/73 Heading E1F Earth boring apparatus comprises a drill string 1 and a cutter head 6 lockable within the string and comprising a drill bit 2, reaming bits 3, a spearhead 78 and latches 9 engagable with recesses 19 in the drill string to lock the head within the string and removable from the recesses by applying upward force to the spearhead. To retrieve the cutter head from the drill string a flexible hose 100 (Fig. 16) is connected to the spearhead by jaws 111 so that a nozzle 105 connects the hose to a passage 85, 82, 86, 35, 26 through the head. Water is supplied by the hose at a lower pressure than used for drilling so that a valve 29 closes to prevent flow to a turbine 4 driving the bits and a piston 69 moves to retract the reaming bits. An upward pull on the hose moves the outer part 7 relative to the part 8 of the head to retract the latches and further upward pulling removes the head from the string. A new head is fed down the string by water pressure which acts on the spearhead to close the passage through the head. When the head lands on a seat 12 adjacent the bottom of the string the part 7 moves to open the passage to permit the latches to engage the string, and the water pressure opens the valve 29 to supply and drive the turbine and moves the piston 69 to project the reaming bits. The bit 2 may be a core bit having a core tube. In a modification (Figs. 21, 22 not shown) the cutter head is without the turbine, the head being rotated by rotating the drill string.
