とを特徴とするシールド掘進機。An appropriate number of shield jacks are arranged inside the shield hull, and a sand discharge device is installed, and a cutter head is rotatably supported in the front opening of the shield hull, and the cutter head is rotatably supported in the front opening of the shield hull. A partition is provided at a slightly further rear location to form a chamber, and while the cutter head is rotated, the shield jack is extended to excavate the ground, and at the same time, a viscosity imparting agent is injected and the soil and viscosity imparting agent are stirred. In a shield excavator that mixes the mud to form mud, fills the chamber with the mud, and discharges the mud from the chamber to the outside using a sand discharge device while holding the face with the earth pressure, an opening is formed in the bulkhead at the rear of the chamber. The shield excavator is characterized in that the earth and sand discharge device is configured by connecting one end of an earth removal tube to the opening, and providing an earth removal port that can be freely opened and closed at the other end of the earth removal tube.
