FIG. 1 and FIG. 2 show a container equipped with a sewage leak prevention device according to an embodiment of the present invention, in which dust is compressed and filled by a compactor at a relay station (not shown). It is supposed to be done. On the rear surface of the container 1, there is provided a tailgate 3 as a main gate that closes the first opening 2 provided on the rear surface by sliding contact with the peripheral edge thereof. The tailgate 3 has vertical frames 4 and 4 each of which has a substantially U-shaped cross section and extends in the vertical direction at left and right positions on the outer surface thereof. The upper end of the frame 4 is pivotably supported via a horizontal axis O. The container 1 is loaded with dust by a compactor, loaded on the chassis of a container transport vehicle (not shown), transported to the dust discharge site, and the tailgate 3 is opened as the chassis tilts to open the dust. Is to be discharged.

Further, in the substantially central portion of the tailgate 3, a second oblong opening 6 provided in the approximately central portion is formed so as to be closed by sliding contact with the peripheral edge thereof. The sub-gate 7 formed in a substantially matching shape is provided. On the rear surface of the sub-gate 7, there is provided a fastening portion 10 for holding the sub-gate 7 in a closed state. The fastening portion 10 is attached to the sub-gate 7 with the second opening 6 closed, from the left and right sides via a pair of upper and lower through holes 4a, 4a extending in the left-right direction of each vertical frame 4 of the tail gate 3. The pair of left and right bar-tightening members 8 integrally having the upper and lower bar-tacking bars 8a, 8a to be inserted hold the sub-gate 7 in a closed state. Then, the sub-gate 7 is removed by being fixed to an extruding plate (not shown) that is reciprocally operated in the compactor while the container 1 is fixed to the compactor, and the sub-gate 7 is substantially The dust is compressed and transferred into the container 1 through the second opening 6. In this case, the moisture contained in the dust is squeezed as sewage by the compression transfer of the dust into the container 1. Numerals 9 and 9 are lateral beams extending in the left-right direction at the upper end and the substantially central portion of the tailgate 3, and the second openings 6 are opened between the lateral beams 9 and between the vertical frames 4.

Further, as a characteristic part of the present invention, below the first opening 2, dust particles leaking from the first sliding contact surface 11 between the tail gate 3 and the peripheral edge of the first opening 2 are included. A first gutter 12 is provided below the first opening 2 and extends in the left-right direction so as to catch dirty water. Further, below the second opening 6, the sub-gate 7 and the peripheral edge of the second opening 6 are provided so as to receive the dirty water in the dust that leaks from the second sliding contact surface 13 between them. A second gutter 14 extending in the left-right direction (below the lower lateral beam 9) is provided. At the lower end position of the tailgate 3 located below the gutters 12 and 14, a storage tank 15 as a storage chamber capable of storing dirty water is provided extending in the left-right direction. Further, between the first gutter 12 and the storage tank 15, a plurality of first gutters 12 and 15 are connected so as to guide the waste water received by the first gutter 12 to the storage tank 15. A communication pipe 16 (only one place is shown in the figure) is provided. On the other hand, between the second gutter 14 and the storage tank 15, a plurality of second communication connecting the two so as to guide the wastewater received by the second gutter 14 to the storage tank 15. Tubes 17, ... Are provided.

Further, at the left end position on the lower end of the rear surface of the storage tank 15, there is provided a discharge device 21 capable of discharging the dirty water stored in the storage tank 15. The discharge device 16 is provided in the middle of the discharge pipe 22 and a discharge pipe 22 projecting rearward from the left end position of the lower end of the rear surface of the storage tank 15 and enables discharge of sewage through the discharge pipe 22. Alternatively, the discharge valve 23 is switched so as to be impossible, the biasing spring 24 which is linked to the discharge valve 23 and biases the discharge valve 23 to switch to the position where waste water can be discharged, and the rear wall of the container 1 The front end is fixed to the rear surface of the member member 25 having a substantially U-shaped cross section that extends in the left-right direction and extends rearward. When the tailgate 3 is closed, the discharge valve 23 resists the urging force of the urging spring 24. And a rod-shaped lever 26 with which the rear end abuts so as to switch the position to a position where the waste water cannot be discharged. The first gutter 12, the second gutter 14, the storage tank 15, the first communication pipe 16, the second communication pipe 17 and the discharge device 21 prevent drainage of sewage from the sliding contact surfaces 11 and 13. A sewage leak prevention device 27 is configured. In this case, the lever 26 penetrates the lower left end position of the tailgate 3 and contacts the discharge valve 23 so as not to hinder the opening / closing operation of the tailgate 3. The drain valve 23 is switched to the position where the waste water cannot be drained only when the valve is closed.

Therefore, in the above-mentioned embodiment, the sewage extracted from the dust pushed into the container 1 has the first sliding contact surface 11 between the tailgate 3 and the peripheral edge of the first opening 2, and Each leaks from the second sliding contact surfaces 13 between the sub-gate 7 and the peripheral edge of the second opening 6. Among them, the sewage leaking from the first sliding contact surface 11 is received by the first gutter 12 extending in the left-right direction below the first opening 2, and the sewage received by the first gutter 12 is passed through the first communication pipe 16. Is led to the storage tank 15. On the other hand, the sewage leaking from the second sliding contact surface 13 is received by the second gutter 14 that extends below the second opening 6 in the left-right direction, and the sewage received by the second gutter 14 passes through the second communicating pipe 17. It is led to the storage tank 15 via. That is, the storage tank 15 stores the sewage leaking from the sliding contact surfaces 11 and 13.

At the dust discharge site, the dust inside the container 1 is discharged by opening the tailgate 3. When the tailgate 3 starts to open, the tailgate as shown by the solid line in FIG. 3 When the drain valve 23 is closed, the contact with the lever 26 that was urging the drain valve 23 to the sewage discharge impossible position is released, and the drain valve 23 is urged as shown by the phantom line (two-dot chain line) in FIG. The urging force of the spring 24 automatically switches to a position where waste water can be discharged, and the discharge of the waste water is almost completed immediately after the opening operation of the tailgate 3 is started. In that case, even if filthy water remains in the storage tank 15 when the tailgate 3 is fully opened, the filthy water in the storage tank 15 is discharged immediately before the tailgate 3 is fully closed, that is, immediately before the lever 26 contacts the discharge valve 23. Is performed again, and when the tailgate 32 is fully closed, drainage of the dirty water in the storage tank 15 is surely completed.

[0016] With this, it is possible to reliably prevent drainage of sewage on the way of the container transportation route from the dust stuffing terminal to the dust discharging site by the container carrier, and to protect the environment near the container transportation route.
