Next, the submersible pump 14 is put into the water intake source W such as a river (step S08 in FIG. 7). At this time, a crane 41 provided on the vehicle body 30 can be used. The submersible pump 14 is in a state of being connected to the storage box 21 of the water supply/drainage container 10 by the hydraulic hose 17, but the crane 41 can be freely positioned relative to the water supply/drainage container 10 by moving the vehicle body 30. can be changed. As a result, the work of putting the submersible pump 14 into the water intake source W is facilitated.

Next, the discharge port 12b of the boost water pump 12 and the water destination are connected by the second water supply hose 52 (step S09 in FIG. 7). The work of extending the second water supply hose 52 from the installation point P of the water supply/drainage container 10 to the water destination is performed by a hose extension vehicle 60 acting together with the disaster prevention vehicle 1 .

Next, the operation panel 18 is operated to drive the driving engine 11 mounted in the storage box 21 of the water supply/drainage container 10 . Then, the submersible pump 14 and the boost water pump 12 are driven based on the power of the drive engine 11 to supply water from the water intake source W to the water destination (step S10 in FIG. 7). At this time, the hydraulic pressure from the hydraulic pump 13 driven by the engine 11 is used to drive the submersible pump 14 .

Once the water supply from the water intake source W to the water destination starts, the vehicle body 30 does not need to be near the water supply/drainage container 10, and can be moved to another location to transport another container or the like to increase the operating rate. can be improved.

The water supply/drainage container 10 carries out water supply or drainage work at an installation point P near the water intake source W, but the supporting legs 22 allow the floor surface of the storage box 21 containing the driving engine 11 and the like to be brought into contact with the container. It can be placed at a position higher than the ground G. As a result, even if the installation point P is submerged by the water overflowing from the water intake source W, it is possible to prevent the boost water pump 12 from being submerged.

When the water supply or drainage work by the water supply/drainage container 10 is completed, the withdrawal work is performed in a flow generally reversed to the flow of steps S01 to S10. In this withdrawal work, the transport/drainage container 10 is mounted on the vehicle body 30 . At this time, the vehicle body 30 lowers the container mounting portion 33 of the vehicle body 30 using the air suspension 39 and retreats toward the water supply/drainage container 10 in the independent state with the support legs 22 . It is necessary to perform alignment in the left-right direction so that the support leg 22 does not come into contact with the support leg 22 . In this embodiment, the alignment (position correction) in the left-right direction is performed by moving the vehicle body 30 backward while bringing the guide rollers 35 of the vehicle body 30 into contact with the guide rail portions 25b of the water supply/drainage container 10. 30 is automatically done to keep the support leg 22 away. Since it is more difficult to move the vehicle body 30 backward than it is to move the vehicle body 30 forward, workability is good for the operator who drives the vehicle body 30 .

As described above, according to the disaster prevention vehicle 1 according to the present embodiment, the system for sending and draining water such as the boost water pump 12 and the submersible pump 14 is provided in one storage box 21 as the water sending and draining container 10. Therefore, the system portion for water supply and drainage can be used as cargo of the vehicle body 30 . Therefore, the maximum stable tilt angle can be ensured compared to the case where a system for water supply and drainage such as the boost water pump 12 is directly attached to the chassis. In addition, when loading and unloading the vehicle main body 30, the container mounting portion of the vehicle main body 30 is placed between the load transmitting bottom surface 25a of the vehicle main body 30 and the container ground surface G in the container box 21 that accommodates the system for water supply and drainage. By providing the support legs 22 for moving the container 33 freely forward and backward, the water supply/drainage container 10 can be easily loaded and unloaded from the vehicle body 30 without requiring a large loading/unloading device of the cargo handling arm type. It is possible. As a result, the maximum loading capacity of the vehicle can be ensured by not providing a large-scale attachment/detachment device to the vehicle body 30, so a large-capacity system for water supply/drainage is adopted, and the water supply/drainage container 10 is made large. Even then, the entire system can be sufficiently mounted on the vehicle body 30 . In addition, when the water supply/drainage container 10 is mounted on the vehicle body 30, the horizontal portion of the L-shaped cargo handling arm such as a cargo handling arm type detachable vehicle may be sandwiched between the chassis and the water supply/drainage container 10. There is no As a result, the mounting position of the water supply/drainage container 10 with respect to the vehicle body 30 can be lowered, and excellent running stability can be achieved when the vehicle is running.

Further, by effectively utilizing the vehicle height adjustment function of the air suspension 39 originally provided in the vehicle body 30, a dedicated lifting device for loading and unloading the water supply and drainage container 10 can be attached to the vehicle body 30 and the water supply and drainage container 10. Since it is not necessary to provide it, the maximum load capacity of the disaster prevention vehicle 1 can be increased accordingly. As a result, the large-capacity and large-sized transport/discharge container 10 can be easily transported.
