摘要： PURPOSE:To wind up a driving body on a smaller drum while keeping a good directional controlability on moving forward in the ground with relatively little troubles. CONSTITUTION:A number of driving pipes T are flexibly connected to each other and a hose is contained in the driving pipe T. A part or whole driving pipes T in a jacking system are divided into two in the longitudinal direction. A second joint 3 is provided at the divided pipes 5, 6 so as to freely connect to or separate from each other. When the second joint 3 is constituted, fitting parts 7, 8 are provided at the butt end faces 10, 10 of both divided pipes 5, 6 respectively so that both divided pipes 5, 6 are rotatable as a unit around the axis. And a connection cylinder 11 inseparably jointing the divided pipes 5,6 is equipped to freely fit or release by inserting it on the divided pipes in the fitted condition of both fitting parts 7, 8. The length of the hose H is decided so that both divided pipes 5, 6 can be mutually bent when separated.

摘要： PURPOSE:To make it possible to control a driving course of a driving head by a few driving cycle. CONSTITUTION:Vertical and horizontal positions and attitudes of a driving head 1 in the ground are detected, and a correcting amount for fitting a driving head course to a planned line is separately obtained as a vertical correcting amount Y and a horizontal correcting amount X based on the detected information. The composite vector is obtained as a correcting required amount R from the vertical correcting amount Y and the horizontal correcting amount X. The pressure receiving surface F is turned in accordance with the direction of the required correcting amount R, a direction of the pressure receiving surface F is inverted and controlled to set a driven inversion and driving amount L2 in accordance with the volume of the required correcting amount R, and the driving course is controlled.

摘要： PURPOSE:To prevent the settlement of ground after the execution to promote safety after the execution, to prevent a buried pipe from dirt to make unnecessary cleaning work, etc., of the inside of the buried pipe and to promote work efficiency. CONSTITUTION:A widening reamer 15 for widening a diameter of an underground hole is connected to the front end side of a driving pipe inserted into the ground while excavating the ground. After a buried pipe 11 is connected to the widening reamer 15, when the driving pipe is pulled back to bury the buried pipe 11 into the underground hole, the inside diameter of the underground hole is widened while excavating it by the widening reamer 15. In addition, guide members used in the case the underground hole is excavated and excavated earth 16 are removed to the outside of the ground. The removal of the guide members and the excavated earth 16 to the outside of the ground is made through the space the inside of the buried pipe 11 while absorbing them.

摘要： PURPOSE:To enable the correction of rolling around an axial center of a driving head body. CONSTITUTION:A plurality of driving pipes 4 are connected to each other so that they are capable of bending and, at the same time, a driving head body is connected to the driving pipe 4 of the front end, and an excavation section 6 capable of revolving operation around an axial center X having a pressure receiving surface 7 is provided to the front end section of the head body. After the front end of the excavation section 6 is pushed into the ground in a state to fix a direction of the pressure receiving surface 7 against the head body 5, the driving of the head into the ground is stopped, the excavation section 6 is relatively rotated and operated against the head body 5 under such a state and is restored to a standard, attitude around the axial center X. After that, the excavation section 6 is retreated to set the direction of the pressure receiving surface 7 to a specific angle, and a driving body 1 is again pushed from the basic end thereof under such a state to drive.

摘要： PURPOSE:To secure the straightness of a propulsion passage and also to enable smooth curvature propulsion by connecting adjacent propulsion bodies together via connecting portions in such a manner that the bodies are freely switched from their curvature allowed positions to curvature inhibit positions and vice versa. CONSTITUTION:Adjacent propulsion bodies B, B are connected together via connecting portions J in such a manner as being freely switched from their curvature allowed positions to curvature inhibit positions and vice versa. While the connecting portions J are held in their curvature inhibit positions, forward propulsion of a propulsion device is carried out. Then the propulsion device is drawn out up to a position where it was located before the forward propulsion, and that part which must be curved is switched to its curvature allowed position, and the propulsion device is propelled forward again into the passage of forward propulsion while the curvature allowed position is maintained. Then required curvature propulsion is carried out.
