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.

摘要： When a shield tunneling machine is deviated from the scheduled line while being propelled, the deviation of shield tunneling machine from the scheduled line is detected and according to the obtained data on the deviation of shield tunneling machine from the scheduled line, the propelling direction of shield tunneling machine is controlled. A reflector 7 is mounted on a cutter head 1 provided with a cutter 5, while a target 10 and a screen 14 are mounted on a tail shield 2. Laser beam 9 is sent along the scheduled line. At the beginning of propelling shield tunneling machine A, the target and the screen is taken by s television camera 15. An image of the target and the screen is processed by an image processor 22, and a spot of beam of light projected on the target and a spot of beam of light projected on the screen are stored as the origin O and the origin o, respectively, in an image processing control unit 23. While the shield tunneling machine is propelled, the present image of the target and the screen is taken by the television camera, and processed by the image processor 22. Coordinates of the present spot 10a of beam of light projected on the target 10 and the present spot 14a of beam of light projected on the screen 14a are compared with coordinates of the origin on target O to another place and the origin of screen 0. When it is detected that the present spot 10a of beam of light projected on the target 10 the present spot 14a of beam of light projected on the screen 14a are displaced from the origin on target O and the origin of screen 0, jacks 3a, 3b are operated so that the present spot 10a of beam of light projected on the target 10 the present spot 14a of beam of light projected on the screen 14a are made to coincide with the origin on target O and the origin of screen 0.

摘要： In an abnormality monitoring apparatus of the present invention, a plurality of detectors (13, 14) are arranged at a plurality of positions in the axial direction of a pipeline (11) to detect respective sound waves (37) propagating from a position (B) of occurrence of abnormality. The aforementioned position is calculated from a sound wave detection time difference between the detectors (13, 14) and position between the detectors (13, 14). The apparatus further includes an abnormal waveform memory unit (28) for storing the waveforms of a plurality of kinds of typical abnormal sound waves generated from abnormality on the pipeline (11). A display device (19) displays, on the same image screen, the abnormal waveform stored in the abnormal waveform memory unit and that of the sound wave detected. It is, therefore, possible for a monitoring personnel to readily identify a kind of abnormality occurred.

摘要： Sensors (13,14) detecting each sound wave propagated from an abnormality occurring position with a fluid as a medium are disposed in a number of positions in the axial direction of the piping. The abnormality occurring position is calculated form the differences of sound wave detection timings between sensors and from the distances between the sensors. An abnormal waveform memory portion for storing sound waveforms resulting from a number of kinds of typical abnormalities is disposed and the abnormal sound waveforms stored in this abnormal waveform memory portion and a detected sound waveform are displayed on the same screen of a display device. Accordingly, the operator can easily identify a kind of abnormality. @(38pp Dwg.No.2/9)@.
