Generally, the water intake tip used when taking in seawater etc. consists of a support member 2 that supports the water intake pipe 1 and a velocity cap 3 disposed above the support member 2, as shown in FIG. Seawater or the like is taken in from the water intake port 4 of the water intake pipe 1 via the water intake port 4 formed between the support member 2 and the velocity cap 3. and,
In order to install such a water intake tip in a river and take in a large amount of river water, it is necessary to install the water intake tip with a large volume against the flow of the river, which increases the resistance of the water flow to the fixed part. In addition to the need to increase the strength of the fixed part, it is undesirable for structural reasons such as the occurrence of the so-called scouring phenomenon, in which the bottom of the water in which the support member 2 is buried is undermined by the influence of water current.
This is done by installing multiple water intake tips in parallel.

A plurality of water intake branch pipes 5, 5, . . . can be installed in one construction.
以下、本発明の望ましい実施例を添付図面に基
づいて詳細に説明する。
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
第１図および第２図に示した本考案の実施例に
おいて、取水管１は、鋼製の管体から形成され、
川床Ａに埋設れて設置されている。 In the embodiment of the invention shown in FIGS. 1 and 2, the water intake pipe 1 is formed from a steel pipe body,
It is installed buried in river bed A.
この取水管１の先端部には、先端を二股に枝分
かれさせて取水枝管５，５を形成するとともに、
取水枝管５部位を側面視略Ｌ字状に屈曲して、
各々の先端開口６，６を上方に向けた補助管７が
連結されている。 At the tip of this intake pipe 1, the tip is branched into two to form intake branch pipes 5, 5,
Five parts of the water intake branch pipes are bent into an approximately L-shape when viewed from the side.
Auxiliary tubes 7 are connected with each other, with their respective tip openings 6, 6 facing upward.
支持部材２は、基部２′とデツキ部２″とを有し

れるのである。 Therefore, according to this embodiment, the river flow is guided to the tip opening 6 of the water intake branch pipe 5 through the bar screen 8 of the water intake port 4, and after collecting in the water intake pipe 1, is communicated with the water intake pipe 1. The water is sent to a water conduit (not shown).
なお、第１図および第２図の実施例において
は、取水管１の先端部を二股に枝分かれさせた場
合を示したが、これに限られずに、適宜数に枝分
かれさせてもよいことは勿論である。 In the embodiments shown in FIGS. 1 and 2, the distal end of the water intake pipe 1 is branched into two, but it is not limited to this, and it goes without saying that the pipe may be branched into an appropriate number of branches. It is.
以上の説明から明らかなように、本考案による
取水先端によれば、支持部材は、平面視略コバン

As is clear from the above explanation, according to the water intake tip according to the present invention, the supporting member is formed in a substantially ridge shape in plan view, so that when the water intake tip is installed along a river flow, its projected area can be reduced. It can be made as small as possible.
従つて、河川流による抵抗を小さくすることが
できる上に、全体として洗掘規模を小さくするこ
とができる。 Therefore, not only the resistance due to the river flow can be reduced, but also the scale of scouring can be reduced as a whole.
さらに、複数の取水枝管が一つの取水先端に包
含されているので、一度の施工で複数の取水先端
を設置したと同様の効果を発揮することができ、
設置効率を向上させることができる。 Furthermore, since multiple intake branch pipes are included in one intake tip, it is possible to achieve the same effect as installing multiple intake tips with one installation.
Installation efficiency can be improved.
