All of these devices required large-scale civil engineering work at the bottom of the water, and the water pipes also needed to be buried underground, which involved civil engineering work for tunneling and burying pipes.

This system was designed to discharge water from the water pipe 3', but as mentioned above, it required large-scale civil engineering work, and involved detailed bottom surveying and soil investigation both at the time of planning and during construction. The construction work required temporary water tightening work, which resulted in a long construction period and a large amount of construction cost, which had serious drawbacks.

A water intake device as shown in Publication No. -42829 has been proposed. This device provides a water discharge pipe extending outward from the top of the embankment and connects the water conduit pipe to the upper end of the water discharge pipe facing the reservoir via a rotating joint ring. A water intake body is connected to the water intake body, making it possible to take water by applying the siphon principle.

されるなどの問題点がある。 However, in this device, the water pipe rotates up and down depending on the water level using the rotating joint ring as a fulcrum, so the water intake body is always on the water surface. The structure is such that it cannot be lifted upwards from the water surface. For this reason, maintenance such as cleaning and repair of water intake bodies must be carried out using a boat or other vessel under unstable conditions above the water surface, and maintenance of water intake bodies below the water surface requires However, in some cases, there are problems such as the need for diving work.

The present invention was developed in view of these circumstances, and by applying the principle of the siphon to a water absorption type water intake system, it is possible to omit the large-scale civil engineering work required in the past, and to simply install the work on the embankment. This will not only improve water intake efficiency and significantly reduce equipment costs, but also facilitate the maintenance and management of water intake structures. The purpose is to provide a device that can improve water intake efficiency.

In addition, when the water level decreases and the distance between the upper part of the embankment body and the water surface, that is, exceeds the allowable head, water intake based on the siphon principle becomes impossible. A water pump 44 is attached thereto.

Next, the water intake means will be explained. First, the water control valve 9 is closed, the water intake port 15 of the water intake body 6 is submerged in water as shown in the figure, and then the air valve 12 is opened and the opening/closing valve 41 of the water intake body 6 is closed. With the water pump 1 closed,
3 to inject water from the reservoir 3 into the water suction pipe 4 and the water guide pipe 7. By injecting water, the air in the water intake pipe 14 and the water conduit 7 is released to the outside from the air valve 12, and when the water is fully injected into the water conduit 7 and the water intake pipe 4, which can be lowered downward, the water injection is stopped. Close the air valve 12.

注水は省略しうる。 Next, by fully opening the water control valve 9 and the on-off valve 41 all at once by remote control, the water in the diagonally descending water pipe 7 flows down, and at the same time, the water in the reservoir is sucked up by the water intake body 6 using the siphon principle. From then on, water intake will be carried out continuously. Even if the water level changes, the water absorption and intake continues due to the automatic expansion and contraction action of the expandable water suction pipe 5. When the lift height is small, water injection into the water suction pipe 4 can be omitted.
