機閉塞解除装置。 A cutter head is equipped with a peripheral support drive mechanism at the tip of the shield machine, and an earth pressure chamber is formed by a rear bulkhead on the back of the cutter head, and excavated soil is stored and filled in the earth pressure chamber to apply to the earth pressure and water pressure of the face ground. In an earth pressure type shield excavation machine that performs excavation while generating opposing earth pressure, a cylindrical casing with one end penetrating the bulkhead and the other end located under atmospheric pressure at the rear is provided, and the tip is located inside the casing. A screw blade with a center shaft is rotatably installed so as to be located inside the earth pressure chamber, and the tip of the center shaft is equipped with a nozzle that sprays pressurized water in any direction, and the inside of the center shaft communicates with the nozzle. 1. An apparatus for releasing blockage of a shield excavator, characterized in that an injection hole is formed through which pressurized water passes, and the screw blade is rotationally driven via a rotating ring fixed to the outer periphery of the rear end.
