る。2. Description of the Related Art When a tunnel is constructed using a conventional tunnel excavator, excavated soil excavated by the tunnel excavator is taken into the tunnel and transported to a starting shaft.
The conveyed excavated soil was carried out of the starting shaft, subjected to solidification treatment such as storage or dehydration, and transported to the disposal site. These excavated soils are classified as residual soil or industrial waste depending on the properties of the earth and sand. Generally, of the soil generated by the muddy water shield method, the primary treated soil is left over and the secondary treated soil is industrial waste. In the mud pressure shield method, excavated soil is muddy by pouring water or injecting mud, so it is all industrial waste.

て利用するのが好ましい。In order to achieve the above-mentioned object, a tunnel excavator according to the present invention is a tunnel excavator for digging a water bottom to construct a tunnel. The present invention is characterized in that it is provided with a device for discharging the excavated soil taken into the tunnel excavator to the outside of the tunnel excavator through the drainage pipe. Further, the earth removal recycling apparatus of the present invention includes the tunnel excavator described above and a soil improvement fleet, and the soil improvement fleet accompanies the tunnel excavator and is discharged from the tunnel excavator through the earth removal pipe. The excavated soil is improved by a soil improvement fleet to obtain improved soil, and the improved soil is used as backfill soil. Here, the earth and sand improvement fleet refers to a work boat equipped with earth and sand improvement equipment and the like. In particular, it is preferable to use the soil as a backfill soil for backfilling the tunnel by directly dropping from the soil improvement fleet or passing through a pipe or the like after the improved soil is formed.

(See FIG. 2). The number, size, and arrangement of the excavating cutters 11 are arbitrarily set according to the excavating shape. The tunnel excavator 1 used in the present invention is a tunnel excavator used when a part of the water bottom is excavated to construct a submarine tunnel. Therefore, the entire tunnel excavator 1 is not buried in the ground of the water bottom 5. Since it is used in such a state, it is possible to excavate in a state where the below-described discharging pipe 2 projects from the tunnel excavator 1. The excavated soil excavated by the excavator 11 and taken into the tunnel excavator is conveyed backward by the screw conveyor 12. The conveyed excavated soil is mixed by a mixer 17 as necessary. By mixing, the slurry can be easily pumped by the mud pump 18.

Connect to 8. FIG. 2 shows an arrangement diagram of the discharging pipe 2.
The discharging pipe 2 is preferably arranged so as to protrude into the water from the highest position of the tunnel excavator 1. Since the discharging pipe 2 protrudes into the water or the atmosphere, the resistance which deforms the pipe does not act on the discharging pipe 2.

きる。As described above, the tunnel excavator and the earth discharging and recycling apparatus of the present invention have the following effects. <B> Reclaim the excavated soil that is usually treated as industrial waste. For this reason, garbage can be reduced and resources can be effectively used, which is effective in protecting the global environment. <B> Improve excavated soil excavated by a tunnel excavator and use it as backfill soil. For this reason, the processing cost of excavated soil can be reduced, and the material cost of backfill soil and the like can be reduced. <C> The excavated soil excavated by the tunnel excavator can be improved by the accompanying sediment improvement fleet, dropped into the sea, and used as backfill soil. Therefore, labor and cost for transporting excavated soil or improved soil are not required. Also, if the improved soil is used immediately, there is no need to stock the improved soil, and there is no need to increase the size of the soil improvement fleet. <D> The excavated soil excavated by the tunnel excavator is discharged to the outside through a discharging pipe. Therefore, there is no need to transport excavated soil in the tunnel leading to the starting shaft. As a result, equipment and labor for transporting excavated soil can be reduced. <E> Excavated soil treatment equipment is not required at the starting base, and the area of the transmitting base can be reduced, and the number of vehicles carried in and out can be reduced.
