According to the first aspect of the present invention, the protection fence fixed to the wave-dissipating opening of the wave-dissipating block structures, quays, piers and other offshore structures and structures of rivers, lakes, etc. of the same type is made of a fiber structure. Since it can be configured, it can be remarkably lightweight and has an effect of significantly improving workability such as installation, maintenance, and replacement.

Further, depending on the choice of fibers to be used, it can be made a protective fence which is extremely tough, weather resistant, seawater resistant, etc., so that the service life can be remarkably extended as compared with conventional products, and boats, driftwood, etc. In the event of a collision, the impact is absorbed and relaxed by the flexibility of the fiber rope, so that not only damage to the protective fence and the wave breaking opening can be prevented, but also damage to the hull, human body, etc. can be prevented.

According to the second aspect of the invention, since the fiber ropes can be bound to each other by the connector, there is an effect that workability such as manufacturing and partial replacement can be improved.

According to the third aspect of the present invention, the lattice-like connection of the fiber rope is a binding structure having a large degree of freedom of deformation of the fiber rope connection, such as a mesh structure or a woven structure that is a cross in the longitudinal direction. Therefore, even if an impact load equal to or higher than the designed tensile strength of the fiber rope is applied, the load can be dispersed, and the effect of absorbing and relaxing the impact load can be further improved.

According to the invention of claim 4, not only is the binding portion between the fiber ropes to have a standardized and strong splice structure, but the outer periphery of the binding portion is tightly bound with a heat-shrinkable synthetic resin. As a result, it is possible to prevent the fiber rope from being pulled out from the binding portion.

According to the invention of claim 5, a core material which is an aggregate of either a strand formed by bundling a plurality of high-strength fibers such as carbon fiber or aramid fiber, or a material rope using two or more strands. Since the protective fence is composed of a fiber rope in which the outer layer of the braid structure having the required properties is formed on the outer periphery of the fiber, the property lacking in high-strength fibers is supplemented by the outer layer of the braid structure. In addition to being able to do, when the strand is the core, since the strands are integrally bound by the braided structure, there is also an effect that the strength of the yarns forming the strand can be integrated,
It has the effect of improving the strength of the protective fence.

According to the invention of claim 6, since the rope according to the invention of claim 5 is a fiber rope having three or more hammers as one strand, the strength of the protective fence is extremely strong. The effect is that the scope of application of the protective fence made of fiber rope can be significantly expanded.

According to the invention of claim 7, since the outer periphery of the core material using the strands in which a large number of high-strength fibers are bundled is reinforced by the synthetic resin layer, the strength such as the tensile strength of the core material is Since it is close to the sum of the strengths of a large number of bundled high-strength fibers and the strength of the synthetic resin layer, it is composed of a fiber rope formed by three or more striking numbers and this fiber rope. This has the effect of facilitating the estimation of the strength of the protective fence and facilitating the selection of the protective fence corresponding to the installation location.

According to the invention of claim 8, the outer layer of each strand of the high-strength fiber constituting the fiber rope is weather resistant,
Since it is made of a fiber material having excellent wear resistance, the strength of the protective fence can be estimated even though it is a stronger protective fence than the invention of claim 7, and the strength of the protective fence can be estimated with high accuracy. The effect that can be achieved is achieved.

According to the ninth aspect of the present invention, since the luminescent, light-saving and fluorescent yarns are arranged in at least a part of the outer layers of the multi-layered and multi-layered fiber rope, cloudy weather, rainy weather and early dawn with a dark field of view are provided. The effect of making the protective fence visible can be obtained even at dusk, or at night.

According to the tenth aspect of the present invention, since it is possible to provide the protective fence at a relatively low cost, short-term, seasonal installation, etc.
It has the effect of providing an inexpensive protective fence to be installed when a long service life is not required.

According to the eleventh aspect of the present invention, since the outer periphery of the core material is the synthetic resin layer, the fiber rope composed of the material rope, and thus the fiber structure bound by the fiber rope in a lattice shape. Since the synthetic resin layer is the outermost surface, it has a slight cushioning effect when the bow and stern of a boat come into contact with it, and it does not cause scratch marks on the hull, while giving the viewer a sense of security like plastic products. It also has a possible effect.
