Description

Detailed Description of the Invention

[0001]

The present invention relates to a pumping method suitable for pumping water from a water body such as a pond or a river to the land side, emergency drainage from the land side to a water body such as a river at the time of flooding, and drainage for temporary construction of civil engineering. And concerning the drainage method.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
It is known that water is pumped to the land side from water areas such as ponds and rivers. In this method, a pump 21 and a prime mover (for example, an engine and a motor) 22 that drives the pump 21 are mounted on a pontoon 20 that is floating in a water area W such as a pond or a river. On the other hand, the pumping pipe 25 is installed along the slope of the embankment 24 constructed at the waterside of the land 23. At one end of the pumping pipe 25, a plurality of branch pipes 25A, 25B, 25C are branched and connected with a vertical interval so as to be able to cope with the water level fluctuation of the water area W.
A valve 26 is provided on each of 5A, 25B and 25C. Further, the other end opening of the pumping pipe 25 is made to correspond to, for example, the irrigation canal 27 on the land 23 side. Therefore,
For pumping water in the water area W, the suction port of the suction pipe 28 connected to the suction side of the pump 21 is immersed in water, and the outlet of the discharge pipe 29 connected to the discharge side of the pump 21 is selected according to the water level of the water area W. The branch pipe 25 is connected to the inlet of the pipe (for example, 25B).
After the valves 26 of A and 25C are closed and the valve 26 of the branch pipe 25B is opened, the pump 21 is operated by the prime mover 22 to pump water. However, the pumping pipe 25 in which a plurality of branch pipes 25A, 25B, 25C in which the valve 26 is interposed is connected in branch, that is, a plurality of branch pipes 25A, 25B, 25C.
Since the pumping pipe 25 having a complicated structure must be used, it has a drawback that fabrication, transportation and installation work of the pumping pipe 25 are considerably difficult.

On the other hand, when the land 23 side is flooded by heavy rain, for example, it is required to drain the flooded water to the water area W. However, in many cases, the road is flooded due to the flood on the land 23 side. Therefore, it is often difficult to transport the drainage facilities to the flood place by land. Further, in the conventional method in which the pontoon 20 is used to pump water from the water area W such as a pond or a river to the land 23 side, the pontoon 20 is equipped with a drainage facility and the water area W is used to reach a submerged place. It is also difficult to transport drainage and perform drainage work.

[0004]

The problem to be solved is that in the conventional pumping by the pontoon, a pumping pipe having a complicated structure must be used.
Transportation and installation work is quite difficult. further,
It is also difficult to carry out the drainage work by transporting the drainage facility to the submerged place by utilizing the water area when it is desired to install the drainage facility in the pontoon.
