Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for connecting oil fences on water.

For example, water (sea) from ships or land tanks, etc.
Oil fences are used to prevent the spread of spilled oil and collect it. Incidentally, this type of oil fence generally includes at least a skirt portion 4, a floating body portion 2, and a weight portion 3, as shown in FIG. 1, for example.

Now, when there is an oil spill, oil fences of unit length are connected and placed on the water, but in this case, there are cases where the oil fence of unit length is connected in advance on land and then pulled out onto the water.
There are cases where a unit length oil fence is thrown onto the water and connected above the water.

In the latter case, since the work is carried out on water, ease of operation is particularly important, and the present invention provides a method for connecting oil fences on water that satisfies this demand.

That is, the method of the present invention uses an oil fence that is provided with a pipe with a slit for inserting a connection adapter in the vertical direction at the end of the oil fence to be connected.
After joining the ends of both oil fences that float on the water and are to be connected, insert the core rod of the connection adapter, which is a sheet-like body with core rods at both ends, into the pipe with a slit for inserting the connection adapter through the slit, and the connected oil It is characterized by preventing oil leakage from between the ends of the fence. In the present invention, the terms "upper" and "lower" refer to the upper and lower sides of the oil fence when it is floating on water.

The present invention will be explained in detail below with reference to the illustrative drawings. The oil fence used in the method of the present invention is similar to the conventional oil fence other than the end portion, for example, as shown in FIG. There is.

That is, as shown in Figs. 2 to 5, the oil fence 1,
Pipes 7, 7' with slits 6, 6' for connecting connection adapters and connecting pipes 9, 9' through which ropes 8, 8' are inserted are attached to the terminals of 1'.

On the other hand, separate core rods 10, 1 are attached at both ends as shown in FIG.
A connection adapter 12 made of a sheet-shaped body, for example, a rubber-coated cloth 11, is prepared. The pipes 7 and 7' have a diameter of 75 mm and are lined with elastic foam such as foamed polyethylene or foamed rubber.
FRP pipes, pipes 9 and 9' have a diameter of 30 mm, for example.
The FRP pipe and core rods 10, 10' are, for example, plastic pipes.

The slitted pipes 7, 7' can be attached to the ends of the oil fences 1, 1' by, for example, gluing a flexible sheet (for example, rubberized cloth) to the outside of the pipes, or by processing fins on the pipes and attaching them to the fins and ends. Attach by fixing the parts. Furthermore, the pipes 9, 9' are attached to the slitted pipes 7, 7' by, for example, adhesive bonding or integral molding.

First, connect the ends of the oil fence. For example, the connection is performed as follows.

(b) Move the oil fence so that the oil fence terminals are facing each other. At this time, pull the ends of the oil fence tension support members 16, 16' (used when pulling the oil fence around on the water) in advance, and then pull the shackle 15.
It will be easier to do the work if you keep it in place (see Figure 2).

(b) Pull the floats 14, 14' at the tips of the ropes 8, 8' onto the ship and secure one end of the ropes C, C'. Next, the other ends D and D' of the ropes 8 and 8' are pulled up onto the ship and secured so that the ends of the oil fence are butted against each other (see Figures 3 and 4).

The above completes the securing connection of the end of the oil fence. However, as it is, it is not sufficient to prevent oil from flowing out from between the fixedly connected terminals, so the following procedure is performed.

(c) Insert the cores 10, 10' of the connection adapter 12 into the connection adapter insertion pipes 7, 7' from the ship through the slits 6, 6' (see Fig. 5).

With the above steps, the connection between both ends of the oil fence is completely completed.

According to the method of the present invention as described above, oil leakage between the joints of the joined ends of oil fences can be completely and extremely easily prevented on the water.
