Claims

[Scope of utility model registration request]

(1) In a sealed peripheral support type sinild excavator that supplies mudding material to the face of a rotating cutter disk, the sealing material is interposed between the sealing part of the bulkhead and cutter disk to seal the cutter chamber. One end of the injection pipe for supplying the slurry material from the slurry pump from the bulkhead side is placed in the space of A closed peripheral support type shield excavator capable of supplying muddy material, characterized in that an injection pipe is connected to the pipe.

(2) partitioning the bearing box in its circumferential direction;
Utility model registration claim 1, characterized in that independent injection pipes are provided in two or more spaces between three or more of the sealing materials, and the communication holes are alternately bored for each bearing box. An enclosed peripheral support type shield excavator that can supply the muddying material described in Section 2.

(3) Utility model registration claim 2, characterized in that the face-side ends of the injection pipes connected to each of the bearing boxes are arranged independently on the inner and outer circumferences of the cutter disk. A sealed peripheral support type shield excavator that can supply the muddying material described above.
