摘要： PURPOSE: To assemble segment pieces with high efficiency in a short time. CONSTITUTION: A front grip 66 and a rear grip 72 are independently turnable. The alignment of a trapezoidal first segment piece 85 and a second segment piece is conducted separately and assembled with high efficiency in a short time. A transfer stroke of a front horizontal cylinder of the front grip 66 is set to be longer than the length of the segment piece 79 in the axial direction and the transfer stroke of the rear horizontal cylinder of the rear grip 72. The interruption between front clamping part 67 of the front grip 66 and the rear grip 72 is eliminated, thereby assembling the trapezoidal first segment piece.

摘要： PURPOSE:To improve the execution property by fitting parallelogrammatic segments constituted of two trapezoidal segments to one trapezoidal segment fixed to the end face of a completed ring, and finally fitting one trapezoidal segment. CONSTITUTION:When a cross section excavated by a shield machine is to be lined with six segments, for example, the long side of a single trapezoidal segment 1 is fixed to the end face of a completed ring R. The first parallelogrammatic segment unit 2 connected with the long sides and short sides of two trapezoidal segments in opposite directions is fitted adjacently to one side of the segment 1. The second parallelogrammatic segment unit 3 formed likewise is fitted to the other side of the segment 1. The last key segment 4 is fitted to the residual interval portion between the segment units 2, 3 with the short side faced to the end face of the ring R. The segments can be accurately assembled, the ring R can be formed via a small number of actions, and the construction period can be shortened.

摘要： PURPOSE:To stabilize the cutting face by a shield excavator when rotating the operating chamber, by rotating the chamber after a mud water chamber installed in the cylindrical body is filled with mud slurry and eliminating the hydraulic pressure variation of the slurry at the cutting face. CONSTITUTION:A mud chamber 44 is provided as a water chamber in the cylindrical body 1 at the circumference of an operating chamber 2. And an inlet or outlet 43 is formed and closed with a manhole 45 so as to enable to supply or discharge mud slurry into or from the mud chamber 44. When replacing bits 9 after excavating works, the cutter arm 8 is fastened and recessed from the opening 12 of the operating chamber 2 into the operating chamber 2 together with the cutter drive device 7. The inlet and outlet 43 is shut by the manhole 45 to fill the mud chamber 44 with mud slurry. Next, the operating chamber 2 is rotated and the cutter arm 8 is contained in the mud chamber 44. Then the mud slurry is discharged from the mud chamber 44 and the manhole 45 is removed to replace the bits 9 by operators entered from the inlet 43 or other ways. In this way, the hydraulic pressure variation against the cutting face 13 can be eliminated.
