に充分な間隔があるために前記のような欠点もなく所期
の目的を達成することができる。Conventionally, various methods have been proposed as a method for preventing pollution diffusion. One of them is a method of surrounding a pollution occurrence place with one shielding film. However, since such a method makes the sealed state as close as possible, when the treated amount of polluted water increases, the polluted water vigorously flows out from the small gap between the lower part of the sheet membrane and the water bottom, so There is a drawback that the intended purpose cannot be achieved because the diffusion speed increases as the flow velocity increases. In addition, as another method, a processing method has been proposed in which the hanging tails are connected in series with a gap. Even if the amount of polluted water treated increases, this method does not have the above-mentioned drawbacks because it has a gap between adjacent hanging tails and there is a sufficient distance between the lower part of the hanging tail and the bottom of the water. Can be achieved.

本発明者は前記した後者の処理法につきさらに種々検討
を加えた結果、本発明方法を完成するに至つた。The present inventor has conducted various studies on the latter treatment method described above, and as a result, has completed the method of the present invention.

することを特徴とする汚濁拡散防止方法である。That is, the present invention hangs a sheet membrane having a gap between adjacent sheet membranes on the water surface portion, while, from the water bottom portion, at a distance from the sheet membrane hung from the water surface portion in the water flow direction. A method for preventing pollution and diffusion, which comprises treating a sheet film with a device provided upright.

次に図面を参照しながら本発明を説明する。The present invention will now be described with reference to the drawings.

まず第１図に示すように水面部にシート膜１をフロート

に示すような展張方法も採用することができる。First, as shown in FIG. 1, the sheet membrane 1 is continuously connected to the float 2 on the water surface so as to hang down, and the sheet membrane 3 is placed on the water bottom at a desired distance (h) from the sheet membrane 1 in the water flow direction. Float 4 to hang it. The sheet film 1 has a gap 5 in the sheet film. As a specific example, for example, a float fence (Patresia (trade name, manufactured by Nippon Solidus Co., Ltd.)) in which a hanging tail is provided on a float is continuously provided and expanded. The present invention can also employ a spreading method as shown in FIG.

Therefore, the flow velocity can be bypassed and the flow velocity of water can be reduced compared to the conventional method. According to the present invention, sedimentation of pollutants can be effectively performed before the sheet membrane,
It is possible to effectively prevent the diffusion of pollution due to the flow velocity.
