【考案の詳細な説明】
本考案は、洗掘防止機能を有する築岸に関す
る。[Detailed Description of the Invention] The present invention relates to a bank building having a scour prevention function.
従来、岸壁、浮ドツク、防波堤等の築岸に船舶
が接岸したりあるいは離岸する場合、船体が築岸
と激しく接触しないように船腹より築岸に向つ
て、噴射水流を出して防止していた。しかしなが
らこのような場合噴射水流が、築岸に当り、下降
流となつて水底の土砂を洗掘したり、またそれに
よつて汚濁を拡散するという問題があつた。 Conventionally, when a ship approaches or leaves a quay, a floating dock, a breakwater, etc., a jet of water is emitted from the belly of the ship toward the shore to prevent the ship from coming into violent contact with the shore. Ta. However, in such cases, there was a problem in that the jetted water flow hit the embankment and became a downward flow, scouring the earth and sand at the bottom of the water, and thereby spreading pollution.
本考案者は、これら従来の欠点を解決すべく
種々検討を重ねた結果、本考案を完成したもので
ある。 The present inventor completed the present invention as a result of various studies to solve these conventional drawbacks.
次に本考案を図面を参照しながら説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は、本考案に係る築岸部の側断面図を示

のうちの下降流が水底４に到達して土砂を洗掘
し、かつ土砂を巻き上げて汚濁拡散を生起する原
因となつていた。 FIG. 1 shows a side sectional view of a bank building according to the present invention, and FIG. 2 shows a side sectional view of a conventional bank building part. First of all, the conventional quay building consists of a water jet 2 emitted from a ship 1 as shown in Fig. 2.
However, when it hit the embankment 3, the flow was divided into an upflow and a downflow, and the downflow reached the water bottom 4, scoured the earth and sand, and stirred up the earth and sand, causing pollution to spread.
本考案は、第１図に示すように築岸３に下降流
を阻止するフイン５を設置したものである。フイ
ンの長さｌは噴射水流を下降流に変換させないた
めに適度な長さが必要であり、例えば30cm以上の
長さが好適である。フイン５の材質も特に制限さ
れないが、可繞性の素材が好ましい。フイン５の
設置方法としては、第３図に示すように板状体を
横列に設置したり、第４図に示すように網目状の
構造体あるいは、第５図に示す円形状の構造体を
設置してもよい。尚フイン５の形状は前記したも

使用できる。 In the present invention, as shown in FIG. 1, fins 5 are installed on the bank 3 to block the downward flow. The length l of the fins needs to be an appropriate length in order to prevent the jet water flow from being converted into a downward flow, and a length of 30 cm or more is preferable, for example. The material of the fins 5 is not particularly limited either, but a permeable material is preferable. The fins 5 can be installed by installing plate-like bodies in horizontal rows as shown in FIG. 3, by installing a mesh structure as shown in FIG. 4, or by installing a circular structure as shown in FIG. May be installed. The fins 5 may have various shapes other than those described above, such as a triangular shape or a diamond shape.
本考案によれば、船舶から出される噴射水流２
が築岸３に当つて下降流となつて水底に達するの
を阻止することができるので、水底部の土砂を洗
掘することなく、且つそれにともなう汚濁の拡散
をも防止し得る利点がある。 According to the present invention, the water jet 2 emitted from the ship
Since it is possible to prevent the water from flowing downward when it hits the bank 3 and reaching the bottom of the water, there is an advantage that the earth and sand at the bottom of the water are not scoured and the spread of pollution accompanying this can also be prevented.
さらに本考案に係るフインを可繞性素材で製作
することによつて防舷材としての機能をも併有す
る。 Furthermore, by making the fin according to the present invention from a permeable material, it also functions as a fender.

３〜５図は、築岸にフインを設置した状態を示し
た築岸の正面図を示したものである。
Figure 1 shows a side sectional view of the embankment according to the present invention, Figure 2 shows a side sectional view of the conventional embankment, and Figures 3 to 5 show the state in which fins are installed on the embankment. This figure shows the front view of the embankment shown.
