摘要： PROBLEM TO BE SOLVED: To facilitate retirement by detachably providing respectively skin plates on one surface, and a plurality of vertical ribs for transmitting jack thrusting force between main girders in a steel frame constructed by an each pair of parallel main girders and coupling plates. SOLUTION: The steel frame 15 is formed of fabricating a pair of parallel main girders 16 and coupling plates 17 at right angles, and fixing an intermediate girder 18 in parallel with the main girders 16 between the central parts. Skin plates 19 are fastened to the steel frame 15 by means of latches. The closed end of a thrust force transmitting member 24 is brought in contact with the main girders 16, and the opened end thereof is in contact with the intermediate girder 18, and an open degree of two sheets of vertical ribs 25 is lessened by making the distance between the nuts of connection metals shorter, so that they are anchored by permitting the vertical ribs 25 to bite in the main girders 16 and intermediate girder 18. In the process of achieving connection between single body tunnels, the thrust force transmitting member 24 is dislodged from the inside of the steel frame 15 by pulling out presser plates of the latches, removing the skin plates 19 from the steel frame 15, and spreading an open degree of the vertical ribs 25. In this construction, the thrust force transmitting vertical ribs and skin plates can easily be dislodged from the steel frame 15.

摘要： PURPOSE:To improve the cut-off function of the junction section of two shielding excavators. CONSTITUTION:A nozzle 11 for washing is installed to the outer ring 12 of a cutter disk at the front end of a shielding excavator. An outermost circumferential cutter 12a at the front end of the outer ring 12 of the cutter disk can be retractable in the radial direction. A cutter disk on the opposite side is retreated into a skin plate 30 under the state, in which the outermost circumferential cutter 12a is retracted. The cutter disk is fitted into a recess formed by retreating. High pressure water is ejected from the nozzle 11 for washing at that time, and the front end of the skin plate 30 is washed. Soil and sand, etc., are removed when the front end of the skin plate 30 is joined with the front end of the skin plate of the shielding excavator on the opposite side, thus acquiring an excellent cut-off function.

摘要： PROBLEM TO BE SOLVED: To provide a lining member which can sufficiently absorb tail clearances on both longitudinal ends of an existing segment, in a width-enlarging type shield excavator.
SOLUTION: The width-enlarging type shield excavator comprises a main excavator (1) and sub-excavators (2a, 2b) provided on both sides thereof. An axial line of each of the sub-excavators (2a, 2b) is displaced relative to an axial line of the main excavator (1) so that excavation may be conducted while enlarging the width. The lining member (4) used for the width-enlarging type shield excavator comprises a plurality of pieces including at least four corner parts (20a) as in Fig. 4. A bolt fitting hole (20A) for fitting a new segment (20A) to the existing segment (20) of each of the corner parts (20a) is formed to be an arc-like long hole having a center of the segment as the center of the arc-like shape.
