のである。[Prior Art] A shield excavator has a cutter face plate rotatably provided in front of a cylindrical shield frame, a cutter chamber is formed within the shield frame, and a screw conveyor is installed in the cutter chamber to discharge earth and sand from the cutter chamber. is connected,
A tunnel is constructed by digging underground with a cutter face plate, taking the excavated earth and sand into the cutter chamber, and extending segments into a hole formed at the rear of the shield frame.

題がある。In order to prevent the face from collapsing, this shield excavator measures the earth pressure inside the cutter chamber, controls the rotation speed of the screw conveyor to keep the upper pressure constant, and controls the amount of earth removed. However, even if the tonosho is held constant, the amount of soil taken in differs, and as a result, there is a problem that a stable face cannot be obtained.

If you do so and dig 1 ring, then NW1
The means 33 open and discharge the top sand 9 into the hopper 29 below. In this case, since the sediment flowing into the measuring tank 32 contains a large amount of water, the water is separated and transferred to the drainage tank 34, and only the sediment is discharged into the hopper 29. If the earth and sand are passed through the basin, there will be no problems such as the muddy water decreasing. In addition, the water from the drain 11134 is sent from the drain pipe 36 to the pressure pipe 26.
It is also possible to supply the water to the water injection ring 47 and use it for transporting earth and sand.
