63−156500号)。(Prior Art) Conventionally, in order to circulate a large amount of water from dams, lakes and marshes, intermittent air pumping apparatuses have been proposed and put into practical use (for example, Japanese Utility Model Publication No. 63-399). However, when the amount of water increases (e.g. 10 million m 3 or higher), and requires a large number of single pumping cylinder (eg, diameter 50 cm, can accommodate approximately 1 million m 3 of water pumping cylinder of length 10 m), administrative complexity Therefore, the technology of a compound cylinder using multiple single pumping cylinders (for example, 2 or more and about 20) was developed (Japanese Utility Model No. 61-200200, Japanese Utility Model No.
63-156500).

Became in time with a relatively small number of pumping equipment at 10 million m 3 or higher) dams, lakes, marshes, etc.. However, large-capacity dams, lakes, swamps, etc. usually have a large water depth (for example,
(40 m or more), there was a possibility that a layer that could not be circulated to the intermediate layer could be formed by a single circulation using the composite cylinder. In such a case, a technique using multi-stage circulation is also known (Japanese Patent Publication No. 1-27606), but the conventional multi-stage circulation is, for example, a method in which the circulation area is divided into a shallow water area and a deep water area, and There is a problem that the water is pumped up to the upper part of the deep water area but not to the water surface. In other words, in order to improve the amount of dissolved oxygen in all water bodies such as dams, it was necessary to pump water near the water bottom to the water surface and mix it with saturated water near the water surface. There was a problem that could not be done.
(課題を解決する為の手段) 然るにこの発明は、複合筒を構成する揚水筒の一部を
長くし、他部を短くして、前記従来の問題点を解決した
のである。(Means for Solving the Problems) However, the present invention has solved the above-mentioned conventional problems by lengthening a part of the pumping cylinder constituting the composite cylinder and shortening the other part.
前記揚水筒の長短については、例えば長い方を30mと
して、短い方を20mとするなど、5m〜20m差が適当であろ
う。従って水深100mのダム等に設置するには、長い揚水
筒を50mとし、中間揚水筒を35m、短い揚水筒を25mとす
るなど三段にすることも考えられる。Regarding the length of the pumping cylinder, a difference of 5 m to 20 m will be appropriate, for example, 30 m for the long one and 20 m for the short one. Therefore, in order to install it in a dam or the like with a depth of 100 m, it is conceivable to adopt a three-stage structure with a long pumping cylinder of 50 m, an intermediate pumping cylinder of 35 m, and a short pumping cylinder of 25 m.
この発明においては、水深によって循環すべき水量が
異るので(例えば浅水域の水量はしばしば深水域の水量
の数倍になる。)、水量の相違を考慮して長い揚水筒
と、短い揚水筒の断面積を定めるのがより合理的であ
る。In the present invention, since the amount of water to be circulated differs depending on the water depth (for example, the amount of water in a shallow water area is often several times the amount of water in a deep water area). It is more reasonable to determine the cross-sectional area of

合理的な循環を再現することができる。(Operation) According to the present invention, since some pumping cylinders constituting the composite cylinder are lengthened and the other parts are shortened, multistage circulation can be performed using one composite cylinder. In addition, rational circulation can be reproduced by making the sectional area of the long pumping cylinder larger than the sectional area of the short pumping cylinder in accordance with the amount of circulating water.
