  Next, the detailed procedure of the volume reduction processing method of the waste disposal site according to the present embodiment will be described.

  For the purpose of volume reduction processing of the waste landfilled at the disposal site, first, the operator digs up the waste 5 from the accumulation section 2 of the landfill 1 by the excavating hydraulic excavator 13, and transfers the digged up waste 5 to the conveyor 10. Into the inlet 25. The waste 5 is transported to the carry-in conveyor 6 on the outer peripheral side (the lower side in FIG. 1) of the accumulation section 1 by the transport conveyor 10, and the waste 5 is placed outside the landfill 1 by the carry-in conveyor 6. Carry into container 4. Then, the screen sorting device 27 sorts into three kinds of sizes, large grain waste 37L, medium grain waste 37M, and small grain waste 37S, among which large grain waste 37L and medium grain waste 37M are input hydraulic pressure. The excavator 31 is charged into the inlet 32 of the crushing device 30, and the crushing device 30 crushes and reduces the volume. The crushed and reduced waste 8 (or the selected small-size waste 37S) is loaded into the carry-out conveyor 7 by the loading hydraulic excavator 33, and the outer peripheral side of the buried section 12 by the carry-out conveyor 7 (upper side in FIG. 1 described above). Transport to. Then, the waste 8 from the carry-out conveyor 7 is transported to a predetermined position in the buried section 12 by the transport conveyor 10 and backfilled. The backfilled waste 8 is accumulated as it is or is solidified by running the excavating hydraulic excavator 13 or the like.

  As described above, in the present embodiment, the sorting / volume reducing device 4 is installed outside the landfill 1, and the carry-in conveyor 6 and the carry-out conveyor 7 are arranged along the outer peripheral side of the landfill 1. As a result, the waste 5 dug up from the accumulation section 2 of the landfill 1 is quantitatively transferred to the sorting / volume reduction device 4 for sorting / volume reduction, and the sorting / volume-reducing waste 8 etc. is landfilled. It can be quantitatively transported to the ground 1 and backfilled.

  In the present embodiment, the carry-in conveyor 6 and the carry-out conveyor 7 are placed on the outer peripheral side of the landfill 1 so as to approach the excavation work range (excavation section 9) and the backfill work range (buried section 12) of the landfill 1. The transport distance within the landfill 1 (specifically, the transport distance from the excavation work range of the landfill 1 to the carry-in conveyor 6 and the transport distance from the backfill work range of the landfill 1 to the carry-out conveyor 7) ), That is, the transport distance of the transport conveyors 10 and 11 can be made relatively short. Such an effect becomes significant when the excavation work range and the backfill work range move.

  FIG. 7 is a plan view for explaining the volume reduction processing method of the waste disposal site according to the present embodiment accompanying the excavation work range and the backfill work range.

As shown in FIG. 7, the excavation work range of the landfill 1 (the right area of the excavation section 9 in FIG. 7) moves to the right in FIG. 7 as the excavation work proceeds. Move from A ₁ → position A ₂ → position A ₃ . At this time, the carry-in conveyor 6 (shown by a broken line in FIG. 7) that is no longer necessary as the transport conveyor 10 moves may be removed. Further, as the backfilling operation proceeds, the backfilling operation range (buried section 12) of the landfill 1 moves to the lower left side in FIG. 7, and the carry-out conveyor 7 is moved to the outer peripheral side of the buried section 12 (upper side in FIG. 7) accordingly. -Further along the upper left side, the carry-in conveyor 6 that has become unnecessary may be moved, and the conveyor 11 is moved from position B _{1 to} position B _{2 to} position B ₃ , for example.

  As described above, in the present embodiment, it is possible to efficiently cope with the movement of the excavation work range and the backfill work range of the landfill 1 by moving the transport conveyors 10 and 11 having a relatively short transport distance. Therefore, it is possible to improve the workability in the volume reduction process at the waste disposal site.

  In addition, in the said one Embodiment, although the carrying-in conveyor 6 and the carrying-out conveyor 7 were demonstrated along the outer peripheral side of the landfill 1 so that the excavation work range and the backfill work range of the landfill 1 might be approached, it demonstrated. Not limited to this. That is, for example, as shown in FIG. 8, a plurality of conveyor devices 45 are connected along the entire outer circumference side of the landfill 1 with the same conveying direction (counterclockwise on the outer circumference side of the landfill 1 in FIG. 8). Of these plural conveyor devices 45, the carry-out conveyor 6 and the carry-out conveyor 7 may be selectively configured to cope with the movement of the excavation work range and the backfill work range of the landfill 1. In this case, compared with the above-described embodiment, the work of rearranging the carry-in conveyor 6 and the carry-out conveyor 7 is reduced, and workability can be further improved.

For example, as shown in FIG. 9, the carry-in conveyor 6 and the carry-out conveyor 7 may be arranged along the outer peripheral side of the landfill 1 from a sorting / volume reduction device 4 to a relatively distant place. That is, as shown in the drawing, the carry-in conveyor 6 ′ is arranged along the outer peripheral side of the accumulation section 2 to the lower right side in FIG. 9 of the accumulation section 2, and the transfer conveyor 10 ′ is arranged from the right side to the left side in FIG. (In other words, in the above-described embodiment, the carry-out conveyor 6 disposed on the lower side in FIG. 7 of the stacking section 2 may be configured as the transport conveyor 10 by being disposed in the stacking section 2. ). In this case, the transfer conveyor 10 ′ can be moved from position C ₁ → position C ₂ → position C ₃ to cope with movement of the excavation work range of the landfill 1. In this case, the comparison with the embodiment, although the transport distance in the landfill 1 is sometimes slightly longer (conveyance distance of the conveyor 10 'at the position C ₁ is relatively long), and input conveyor 6 transport The conveyance distance combined with the conveyor 10 'can be made relatively short.

  In the above embodiment, the carry-in conveyor 6, the carry-out conveyor 7, and the transfer conveyors 10 and 11 have been described by taking as an example a structure that can be moved by being pulled by the excavating hydraulic excavator 13 or the like. Needless to say, the structure may include a traveling body including left and right endless track footwear and the like, and a structure capable of self-propelling.
