業がやりにくいという問題が生じていた。 However, with the earth pressure type shield excavator, the work can be carried out smoothly when excavating clay, but when excavating sand, the sand that has entered the cutter desk 3 does not move, and therefore the screw conveyor 8 It becomes impossible to discharge more water, and excavation becomes impossible.
Therefore, in the case of sand, a bentonite solution or water is added to the sand to improve its fluidity. This caused the problem that the work was difficult to do.

るものである。 The present invention was developed with the aim of eliminating the above-mentioned drawbacks of conventional equipment, and includes a rotatable cutter desk placed in front of the shield body, and a screw conveyor that discharges earth and sand from the cutter desk side to the outside of the shield body. The invention is characterized in that a plurality of screw conveyors are disposed at predetermined positions, and within the cutter desk, a plurality of screw conveyors are disposed radially around the screw conveyor that discharges earth and sand to the outside.
以下、本考案の実施例を図面に基いて説明す
