Abstract

7030. Stone, R. March 26. Tunnelling.-The shield is provided with a bulkhead a', in which is constructed a universal joint d carrying a hose nozzle 4. A revolving airtight cage g permits access to the space in front of the bulkhead without disturbing the pressure. A telescoping s u c t i o npipe f, f<1>, f<2> serves to remove the water and suspended excavated material. The shield is advanced by hydraulic rams h placed between the interior flange i of the bulkhead and the last of the casing-sections b. Inflated hose, placed in semicircular grooves c' of rings c made on the inside of the shield, serve as packing between the shield and casing-sections. Trailer-beams m attached to the bulkhead, passing through guides 20 and clamp-frames n provided with adjusting-screws 18, are used to guide the shield. The materials for the concrete foundation are introduced by manholes l.
