摘要： PROBLEM TO BE SOLVED: To provide a drilling tool for a branch taking-out joint capable of performing drilling work surely with safety even if a gas pressure rises.SOLUTION: A drilling tool includes a cutting unit which moves a cutter moving part of a joint 200 and contains a cutter for cutting into an original pipe, a shutter unit 70 containing a shutter plate 80 which opens/closes a cavity of the cutter moving part of the joint 200, and a stopper unit 110 for attaching a plug 150 for sealing an opening of the cutter moving part of the joint 200. Before sealing the cavity of the cutter moving part with the plug 150 after completion of drilling of the original pipe, a space in the stopper unit 110 opposite the joint side of the shutter plate 80 and a space in the shutter unit 70 on the joint side are communicated with each other by purging assemblies 80, 120 and a hose assembly 140, for a same pressure. Thus, even if a gas pressure in the joint side space is high, the shutter plate 80 is not pressed to a low pressure side, allowing easy opening with less frictional resistance.

摘要： A conduit comprised of double-wall pipes A is laid in the ground by the pipe-jacking method. Each double-wall pipe A comprises inner pipe 1 and outer pipe 2 and is provided with sheath pipe 3 between inner pipe 1 and outer pipe 2 and with check valve 4. Back-filling material supply pipe 11 is moved in sheath pipes 3 from a first vertical shaft. When injecting member F is opposed to check valve 4, at the centre of the conduit, packing means 16, 17 are inflated to be brought into contact with the inside of sheath pipe 3 by which injecting member F is fixed to sheath pipe 3. Back-filling material is driven to a space between packing means in sheath pipe 3, and injected through check valve 4 into space 5 between the outside of outer pipe 2 and the ground. The injecting member is then moved to the next check valve nearest the start vertical shaft and the process is repeated until a first half of the conduit is backfilled. Subsequently the supply pipe is driven along the sheath pipes 3 from the second vertical shaft, and the second half of the conduit is backfilled in the same way.
