装置。 A cutter head chamber 6 with a sealed structure is provided behind the cutter head 3 provided at the front of the shield excavator main body 1, and the mud is excavated while balancing the earth pressure inside the cutter head chamber 6 and the earth pressure at the face. In the shield tunnel excavator, air pressure is supplied to the cutter head chamber 6 to maintain and detect the earth pressure in the cutter head chamber 6, and also to detect the earth pressure in the cutter head chamber 6. An earth pressure control device for a mud shield excavator that restores earth pressure by injecting soil pressure when it has decreased.
