ープ、１２は水面を表わしている。 FIG. 1 is a simplified diagram illustrating a normal usage state of the oil fence or pollution diffusion prevention (hereinafter simply abbreviated as fence) described in detail in FIG. 6.
In Figure 1, 11 is the floating body part of Fuens, 3 is the floating body part 1
A skirt hangs down from 1, 6 is a weight at the tip of the skirt 3, 4 is a reinforcing belt or wire rope for the skirt, and 12 is the water surface.

ース、１５はバルブである。 As shown in FIG. 2, the air chamber forming body (float) 13 made of rubber-coated cloth, for example, is
along both sides of the floating body part 11 in an empty state,
Connect the skirt 3 through the connecting body 14 such as a wire rope at the lower part of the lower reinforcing belt or wire rope 4 of the fence floating body part 11 (make a slit in the skirt 3 with something like a senma tooshi or a knife and connect the connecting body 14 through - 6th
(See imaginary line in figure). (As described later, air chamber forming body 1
When the skirt 3 is inflated, a buoyant force acts upward, which may cause the connecting body 14 to tear the skirt 3. To prevent this tearing, the skirt 3 is passed under a reinforcing belt or wire rope 4. ) As shown in FIG.
is inflated with air, and the floating body part 11 is pushed up above the water surface 12. In FIG. 3, 25 is a hose extending from the air chamber forming body to the compressor or blower, and 15 is a valve.
上記に於いて第３図ｂに示す様に１対の気室
を２対利用する方がよい。 In the above case, it is better to use two pairs of air chambers as shown in FIG. 3b.

又前記で水面上に押し上げると述べているが、
点検、補修の内容により完全に水面上に押し上げ
る必要がない場合もある。 In addition, during the above inspection and repair, inspection of the fence,
If the repaired area is close to the anchorage 16 of the fence (the fences are anchored to the anchors at intervals of 10 or 20 m, for example - see Figure 4), forces may be applied to the anchor wire 17, especially if there is a current. function, inspection using the air chamber forming body 13 of the present invention,
It may be difficult to push the repair above the water. In that case, anchor wire 1 where the force is working
7 may need to be removed from the fence for inspection and repair. (In Figure 4, 18 is an anchor such as a concrete block, and 19 is the bottom of the water.)Also, although it was mentioned above that it is pushed up above the water surface,
Depending on the nature of the inspection or repair, it may not be necessary to raise the vessel completely above the water surface.
一方流れが早い場合、或いはスカート部の点
検、補修が必要な場合は第７図の様な気室形成体
１３の使用を行う。即ちスカート３下端をめぐら
して連結体１４で気室形成体１３を連結する。 On the other hand, if the flow is fast or if the skirt portion requires inspection or repair, an air chamber forming body 13 as shown in FIG. 7 is used. That is, the air chamber forming body 13 is connected by the connecting body 14 around the lower end of the skirt 3.
これは、前者の場合に於いては、スカートが長
く垂下しているとその垂下深さに比例して水流抵
抗が発生する、この力は下向であり、フエンスを
沈める作用をもつている。従つてスカート下端か
ら持ち上げ垂下深さを小さくすると水流抵抗が小
さくなり浮かせ易いからである。 This is because in the former case, if the skirt hangs down for a long time, water flow resistance occurs in proportion to the depth of the skirt, and this force is downward and has the effect of sinking the fence. Therefore, if the skirt is lifted from the lower end to reduce the hanging depth, the water flow resistance will be reduced and it will be easier to float.
後者の場合に於いては、水面上から又は水面付
近でスカートの点検、補修作業を行うため、スカ

る。 In the latter case, it is desirable to float the skirt above or near the water surface in order to perform inspection and repair work on the skirt from above or near the water surface.
気室形成体は例えば第５図の如きもの（例えば
ゴム引布製）であり、図中２０ははとめ孔、２１
