BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to emergency drainage at the time of water disaster,
The present invention relates to a hose laying method for drainage by a drainage pump car used for drainage of civil engineering temporary construction work or water supply and drainage for agriculture.

[0002]

2. Description of the Related Art Conventionally, as a drainage pump car used for emergency drainage at the time of water disaster, drainage for temporary construction works or water supply and drainage for agriculture, a crane used for loading and unloading equipment such as pumps on trucks, Multiple drainage pumps (submersible pumps) and drainage pumps with floats, private generators that supply power to the drive sources (motors) for these drainage pumps and their operation panels, drainage hoses connected to the drainage outlets of each drainage pump, each Cab tire cable that electrically connects the drive source of the drainage pump and the operation panel of the private power generator, main floodlight for night work, auxiliary floodlight for spot lighting, and portable power generation that supplies power to this auxiliary floodlight Some are equipped with devices such as devices. According to this type of drainage pump vehicle, if it reaches the water level of the drainage or water supply / drainage site by self-propelled, after connecting the drain hose and the cable of the tire cable, install the drainage pump in the water by the crane. The drainage is performed by supplying power to the drive source of the drainage pump by operating the private power generator and operating the drainage pump.

By the way, in the conventional drainage pump vehicle,
If the ground at the drainage or water supply / drainage site and its surroundings is hard, the drainage pump car can be driven to the water's edge, but if the ground is soft, it cannot be driven to the water's edge. Therefore, the stop position of the drainage pump car is restricted to a place relatively remote from the water's edge. Therefore, it is necessary to manually carry out various works such as the work of transporting the drainage pump with a float unloaded from the platform by the crane to the water's edge, the work of laying the drainage pump from the water's edge to the water, and the work of connecting and connecting the tire cable. . In other words, the work of transporting the drainage pump unloaded from the loading platform by the crane to the waterside by the hand cart, the construction of the tilted guideway at the waterside, the work of laying the drainage pump underwater using the constructed tilted guideway, etc. Work must be performed by many workers.
Moreover, since these operations are extremely troublesome and difficult, the workability is poor and the quick start of drainage after reaching the drainage or water supply / drainage site is hindered. Further, since a private power generator for operating the drainage pump, a control panel, etc. are required, there is a disadvantage in that the equipment becomes large in size and economically disadvantageous.

Therefore, the applicant of the present invention has filed Japanese Patent Application No. 4-33.
In No. 269, even if the drainage or water supply / drainage site and the ground around it are soft, they can be self-propelled to the water's edge, and the operation of lowering the amphibious vehicle from the carrier bed of the transport vehicle, from the lowered position to the waterfront Operation to move by running, operation to launch amphibious vehicle from the water's edge to move it to the water depth area where drainage pump can operate, operation to drain amphibious vehicle after stopping amphibious vehicle in this water depth area, drainage Operation to stop the operation of the drainage pump after completion,
A series of operations such as an operation of returning the amphibious vehicle to the water's edge and an operation of moving the amphibious vehicle from here to the transportation vehicle and placing it on the bed can be configured to be performed by remote control, thereby improving workability. I proposed a drainage pump car that can do it.

When laying a hose when draining water with this drainage pump car, a plurality of standard length drainage hoses are wound around each unit and loaded on a transportation vehicle or another truck and transported near the drainage site. , Unloading the amphibious vehicle from the carrier bed of the transportation vehicle to the ground near the drainage site, and unloading the plurality of standard length drainage hoses alone mounted on the transportation vehicle or another truck to the ground, for example, as shown in FIG. As described above, while the drainage pump vehicle moves to the water's edge and stands by, the standard length drainage hose H2 is replaced with the standard length drainage hose H1.
In comparison with the standard drainage hose H2, the standard length drainage hose H3 is manually transported with a predetermined interval, that is, an interval substantially corresponding to the length of the standard length drainage hose alone. Open and transport manually, and then transport the standard length drainage hose unit H4 manually to the standard length drainage hose unit H3 at a predetermined interval.
While unwinding 1, H2, H3, and H4, as shown in FIG. 11, they are connected to each other to form a series of aboveground drainage hose H, and then the drainage pump car waiting at the waterside This is done by the procedure of connecting the inlet of the aboveground drainage hose H to the drainage pump. In this way, in the work of laying a hose, in which a fixed-length drainage hose unit that has been temporarily placed on the ground near the drainage site must be manually transported at predetermined intervals, it requires a large number of workers. However, since it requires a long working time, it takes a relatively long time from the arrival at the site to the start of launching the drainage pump car, which naturally has a drawback that the drainage start is delayed.

[0006]

The problem to be solved is that it takes a relatively long time from the arrival at the site to the launch of the drainage pump vehicle. In other words, the start of drainage is delayed.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic side view showing an example of a drainage pump vehicle applied in the first invention, and FIG. 2 is a configuration diagram showing an example of a vehicle drive system and a drainage pump drive system. The pump vehicle is an amphibious vehicle 1, a boat-shaped closed body 2, and a pair of left and right crawlers 3 capable of running on soft ground.
It consists of a crawler car with A and 3B,
The boat-type closed body 2 is equipped with an engine 4, two drainage pumps 5A and 5B, and two hydraulic pumps 6A and 6B operated by the engine 4 to switch and operate an electromagnetic or electric switching valve 7A. Accordingly, pressure oil is supplied from one of the hydraulic pumps 6A to the traveling motor 8A or the drainage pump driving motor 9A to be operated, and the electromagnetic or electric switching valve 7B is switched to operate so that the other hydraulic pump 6B is operated. Pressure oil is supplied to the traveling motor 8B or the drain pump driving motor 9B to operate. The suction ports of the drainage pumps 5A and 5B penetrate the bottom of the boat-shaped hermetically sealed body 2 in a watertight manner and open at the lower side of the bottom. The hydraulic pumps 6A and 6B are directly connected to the engine 4 and are of a variable displacement type bidirectional flow, and an oil flow direction and an amount of discharged oil are adjusted by a regulator. The output shaft of the traveling motor 8A is connected to the drive side wheel of one crawler 3A, and the output shaft of the traveling motor 8B is connected to the other crawler 3A.
It is connected to the drive side wheel of B. The switching control of the switching valves 7A and 7B, the operation / stop and rotation speed control of the engine 4, the control of the oil flow direction and the discharge amount of the hydraulic pumps 6A and 6B, and the like are not shown in the figure. It is designed to be remotely controlled by a controller configured by a reception controller that receives a radio signal transmitted from the device and outputs a control signal.

As shown in FIG. 3, the vehicle drive system and the drainage pump drive system may be configured separately from the vehicle drive system and the drainage pump drive system. That is, the vehicle drive system includes the engine 4, two hydraulic pumps 6A and 6B operated by the engine 4, and a drive unit of the amphibious vehicle 1 driven by these hydraulic pumps 6A and 6B, that is, a pair of left and right crawlers 3A. , 3B hydraulic motor 1 for transmitting power separately
The drainage pump drive system may include a drainage engine 11A that drives the drainage pump 5A, a speed reducer 12A, and a drainage engine 11B that drives the drainage pump 5B and a speed reducer 12B.

With such a configuration, as shown in FIG.
The amphibious vehicle 1 and the hose reel 15 around which the drainage hose 14 is wound are loaded on the carrier of the transport vehicle 13 such as a truck and transported to the vicinity of the drainage or water supply / drainage site. When it reaches near the site, the amphibious vehicle 1 is self-propelled by the remote control of the above-mentioned control device to descend from the bed of the transport vehicle 13, and the start end of the drain hose 14 is connected to the drain pump 5B. It is launched toward the water's edge as in 5, and launched from here. As a result, the drain hose 14 is pulled and delivered from the hose reel 15. That is, the drainage hose 14 can be laid in parallel with the movement of the amphibious vehicle 1. When the amphibious vehicle 1 reaches the drainage point and stops, the drainage hose 14 is removed from the hose reel 15, and the terminal discharge port is laid on the drainage side (for example, the outside of the embankment) as shown by a virtual line. After that, Japanese Patent Application No. 4-3326
Drain in the same way as No. 9. When draining water by using the other drainage pump 5A together with the one drainage pump 5B, the inlet of the drainage hose wound on another hose reel (not shown) is connected to the drainage pump 5A. By doing so, two drainage hoses can be laid simultaneously. Alternatively, the hose reel 15 around which the drainage hose 14 is wound may be unloaded from the loading platform of the transport vehicle 13 and installed on the ground, and then connected to the drainage pumps 5A and 5B and installed. Furthermore, the distance from the position where the amphibious vehicle 1 is dropped from the transportation vehicle 13 to the drainage point differs depending on the site. That is, the hose reel 1
Since the distance from the installation position of 5 to the drainage point differs depending on the site, a plurality of hose reels 15 around which drainage hoses 14 having different lengths are wound are prepared in advance, and the drainage length corresponding to the distance is prepared. The hose reel 15 around which the hose 14 is wound may be selected and used.

As described above, since the drain hose 14 can be towed by the movement of the amphibious vehicle 1 and fed out from the hose reel 15, it is possible to omit the labor-intensive laying by manpower. Therefore, the time from the arrival at the site to the start of the launch of the drainage pump vehicle can be significantly shortened, and the drainage can be started quickly after the arrival at the site and labor saving can be achieved.

FIG. 6 is a schematic side view showing an example of a drainage pump vehicle applied in the second invention, which is equipped with the vehicle drive system and the drainage pump drive system shown in FIG. 2 or 3. The same or corresponding parts as those of the first invention are designated by the same reference numerals, and detailed description of the structure and operation will be omitted.
In the second invention, for example, two hose reels 15 (however, only one hose reel 15 is shown in FIG. 6) driven by the engine 4 or the hydraulic pump 6A or 6B are mounted on the amphibious vehicle 1. The inlet of the drain hose 14 wound around the hose reel 15 is the drain pump 5
It is connected to A and 5B. The hose reel 15 is configured as shown in FIGS. 7 and 8, for example.

That is, the hose reel 15 has a frame 151 and a drum 152, and the drum 152 is rotatably supported by bearings 151A and 151B of the frame 151 via one drum shaft 153 and the other drum shaft 154. A driving means such as the engine 4 or the hydraulic pump 6A or 6B described above is connected to one of the drum shafts 153 to drive the drum 152 to rotate in the forward and reverse directions. The other drum shaft 154 is a hollow shaft having one end open and the other end closed, and the end of the primary side 14A of the drain hose 14 is detachably connected to one end of the drain shaft 154, and the start of the primary side 14A is a drain pump. It is detachably connected to the discharge port of 5B. The hollow portion of the other drum shaft 154 communicates with the outside of the drum 152 via two joints 155 and 156 connected to the other end side, and the joint 156 is attached to and detached from the starting end of the secondary side 14B of the drain hose 14. The secondary side 14B is connected so that it can be wound around the drum 152. However, when the hose diameter is large,
Since the drum diameter is structurally increased when the joints 155 and 156 are provided, only a hose may be wound and a reel without the joints 155 and 156 and the hollow drum shaft may be used.

Therefore, as shown in FIG. 9, as the amphibious vehicle 1 moves from near the drainage site to the water's edge and is further launched and moved, the hose reel 15 mounted on the amphibious vehicle 1 is moved. By driving the drain hose 14 in the unwinding direction, the drain hose 15 is driven from the hose reel 15.
4 can be laid out while feeding. That is, the drainage hose 14 can be installed in parallel with the movement of the drainage pump vehicle. Therefore, the time from the arrival at the site to the launch of the drainage pump car can be significantly shortened, and the drainage can be started quickly after the arrival at the site.

[0018]

As described above, according to the present invention, since the drainage hose can be laid by the drainage pump truck in parallel with the movement of the drainage pump truck, the drainage hose laying by manpower, which is considered to be complicated, can be performed. It can be omitted. Therefore, the time from the arrival at the site to the start of the launch of the drainage pump vehicle can be significantly shortened, and the drainage can be started quickly after the arrival at the site and labor saving can be achieved.
