Claims

[Scope of utility model registration request]

An upper mud-making chamber defined by a partition wall is provided at the front end of the cylindrical shield machine body, a cutter blade that penetrates the partition wall and protrudes forward is disposed in the mud-making upper chamber, and a rear part of the cutter blade is disposed in the upper mud-making chamber. A stirring blade for stirring earth and sand is provided in the mud-making chamber, and while the cutter blade is rotated to excavate the face, mud material is injected into the excavated earth and sand and mixed by the stirring blade in the mud-making upper chamber. Converted to mud (
2. In a mud pressurizing type shield machine that maintains the mud production upper chamber at a required pressure to counter the ground pressure using the converted mud, a fixed blade is installed in front of the partition wall, and a fixed blade is installed between the rotating trajectory of the stirring blade. This mud pressurized shield machine is characterized by being removably attached to the area.
