DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing the spread of polluted water, which is installed around a construction area in a sea reclamation work or the like.

[0002]

2. Description of the Related Art In a sea reclamation work, a large amount of polluted water flows out onto the sea around a construction area. In order to prevent the diffusion of the contaminated water, a contaminated water diffusion prevention device is installed so as to surround the construction area.

[0003] As this polluted water diffusion prevention device, a device having a structure in which a curtain body sinks to a predetermined depth in water with respect to a floating body floating on the water surface has been widely used.

[0004] In such a polluted water diffusion prevention device, generally, a main belt is attached along a lower portion of a floating body cover that covers the floating body, and an upper edge of a curtain body is connected to the main belt portion by an appropriate connecting means. The body is configured, and as a method of installing the apparatus, a method is adopted in which the required number of unit bodies are combined according to the installation form, and a fixing cable is stretched from the main belt portion to anchor. Here, for the mutual connection of the main belt ends of the adjacent units, a connection fitting attached to the main belt end, for example, a general-purpose connection D ring or a shackle is used. Is attached using a stopper that penetrates the main belt.

[0005]

When the above-mentioned apparatus for preventing the diffusion of polluted water is installed on the sea, external pressure such as tides and waves is applied to the apparatus. The strength of the connecting portion at the end of the main belt greatly affects the resistance of the device to the external pressure. In particular, the influence of the waves is large, and the pressure of the waves is repeatedly applied over time, so that the tensile strength near the attachment of the connecting bracket at the end of the main belt decreases.
The main belt may be torn from this part and break.

[0006] That is, as in the prior art, in the case of using a stopper that penetrates the main belt as a structure for attaching the connecting bracket to the main belt, the tension applied to the main belt is received by the stopper through hole. Therefore, the weakening of the main belt proceeds from the enlarged tearing of the stopper through hole.

Therefore, the present invention reinforces the end of the main belt without changing the original function of the main belt, does not reduce the tensile strength of the main belt, and exhibits a long-term stable performance of polluted water diffusion. It is an object to provide a prevention device.

[0008]

Means for Solving the Problems To achieve the above object, a pollution water diffusion prevention device of the present invention comprises: A main belt is provided along the lower part of the floating body cover that covers the floating body, and a multilayer belt part is formed at the end of the main belt.
With appropriate intervals on both the front and back sides of the multilayer belt part.
With a reinforcing plate, and apply multiple

The third layer consisting of a continuous belt body folded at the middle part and the third layer
Four layers of reinforcement belts are layered, and the third and fourth layers are supplemented.
The strong belt is sewn in advance and its folded end
The locking end portion is formed by sewing a rope-shaped filling into the portion .

According to the present invention thus constructed, the thickness of the multilayer belt portion formed at the end of the main belt is substantially increased, and the tensile strength is increased. Further, in the multilayer belt portion, the locations for receiving the tension applied to the main belt are dispersed at appropriate reinforcing plate portions provided at appropriate intervals, so that the main belt is locally weakened. There is no. Further, since the bending of the main belt is free even in the multilayer belt portion, the original function of the main belt can be maintained.

In the present invention, a multilayer belt portion is formed.
To the main belt itself and the first layer, a reinforcing belt of the second layer to polymerize on this in advance, when the configuration was sutured to the main belt, the suture including a reinforcing belt of the second layer, the floating body Since the main belt is sewn to the cover at the same time as the sewing operation, the end of the main belt having the second-layer reinforcing belt is handled in the same manner as a single unit from the viewpoint of assembling and manufacturing the device, and workability is improved.

Further, in the present invention, the third layer and the fourth reinforcing belt which is layered over the reinforcement belt of the second layer is constituted by a continuous belt body folded in the middle portion, both reinforcing belt, previously, The structure in which the locking end portion is formed by sewing the rope-shaped padding in the folded end portion while suturing can further increase the tensile strength of the end portion of the main belt from a practical point of view. In addition, since the foremost contact plate for clamping and fixing the multilayer belt portion also serves as a connection fitting provided at the end of the main belt, the edge of the foremost contact plate is locked to the locking end portion and is hooked on the main belt. By receiving the tension, the tensile strength of the main belt is also increased here. Further, the reinforcing belts of the third layer and the fourth layer which have been sewn in advance are treated as a single unit from the viewpoint of assembling and manufacturing the device, and workability is improved.

In the present invention, the main belt and the respective reinforcing belts are made of polyester material, and the stoppers of the multilayer belt portion formed by laminating these main belts and the respective reinforcing belts are previously subjected to the stoppers by heating. When the through-hole is formed, the fiber end is melted and hardened by frictional heat generated at the time of the perforation, and the through-hole becomes an integral body, thereby increasing the tear strength of the through-hole wall. Also, since the diameter of the stopper through hole can be ensured, the work of inserting the stopper can be easily performed at the time of assembling and manufacturing the device, and the workability is improved.
