Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wave breaking device for protecting structures and the like from waves and for increasing the calmness of water bodies, and in particular, a plastic fiber having an appropriate gap. The present invention relates to a light-weight wave-eliminating device having high efficiency in wave-elimination by employing a wave-eliminating member.

"Conventional technology" Conventionally, in order to increase the calmness of the bay, the shape of the bay has been complicated to prevent the wave from resonating in the bay and increasing the wave height. There has been some effort to absorb the energy of the waves. Furthermore, as a wave-dissipating structure having an excellent wave-dissipating effect, there has been a structure in which thin pieces such as a porous body and a film are bundled in a cilia structure, and the thin pieces and the like are sealed in a skeleton.

[Problems to be Solved by the Invention] However, the above-described conventional wave breaking method that complicates the shape of the bay also complicates the shape of the port in the bay, which hinders navigation of the ship or occupies the entire bay. There was a problem that the proportion of lodgings was reduced. In addition, the wave absorber that stacks irregularly shaped blocks has a problem in that the blocks are stacked not only near the water surface where the motion of the water particles is large, but also in multiple layers below the water surface, so that the cost is high for the effect. In addition, in the portion where the blocks are stacked, there is a problem that not only is it extremely difficult for the ship to approach, but also the quay behind the blocks cannot be used as a landing place even in a quiet period. Wave breakers and breakwaters composed of deformed blocks are suitable for long-term protection of harbors and shorelines from high waves, but they increase the cost of laying blocks and the construction period is relatively long. In addition to the period, there is a problem that the driving of the sheet piles and the like is not easy under the waves. Next, the wave breaking device made of a thin piece of film or the like has a problem that the enclosed film dust or the like floats and contaminates an experimental water tank or the like. Further, there is a problem that if the use period is long, the flakes or the like will end up and the wave-elimination efficiency will decrease. In addition, when aluminum scrap is used for the flakes, there is a problem that oil must be removed.

"Means for Solving the Problems" The present invention has been devised in view of the above problems, and the present invention provides a wave breaking device for increasing the calmness of a storage pond such as a pool or a pond. The wave breaking member is formed of a fiber material having a void, and the wave breaking member is characterized in that a through hole for inserting a rope for positioning the wave breaking device is formed.

Then, the wave-damping member may be made of a fiber material having a specific gravity of 1.0 or less, or may be provided with a buoyancy generating means such as a hollow portion to provide a wave-damping device having a floating structure.

Further, the present invention includes a first step of arranging the framing member and a second step of laminating a fiber material containing an adhesive around the framing member.

[Operation] According to the present invention configured as described above, a through hole is formed in the wave canceling member, and a rope for positioning the wave canceling device can be inserted into the through hole. In this case, the wave-breaking device can be made to have a floating structure by forming the wave-breaking member from a fiber material having a specific gravity of 1.0 or less, or by providing a buoyancy generating means such as a hollow portion.

Further, according to the present invention, a wave breaking device can be manufactured by arranging a frame member and laminating a fiber material mixed with an adhesive around the frame member.

Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a wave absorber mounted on a quay, 1 is a wave absorber main body, and a frame member 2 and a wave absorber are shown. And a member 3. The frame member 2 is one of support members or holding members, and is made of a metal such as steel, a composite material made of plastic or the like, another synthetic resin, or the like. The frame member 2 may be made of any material, but is desirably lightweight and strong. In particular, by manufacturing the frame member 2 into an appropriate shape, it is possible to design a wave-dissipating construction adapted to use in a local wave or in a bay. In the present specification, the frame member 2 is a member for supporting or holding the wave canceling member 3, and may be a frame member or the like configured inside the wave canceling member 3, A support frame member or the like configured outside may be used. That is, the frame member 2 only needs to support or hold the wave canceling member 3. The wave-absorbing member 3 is for absorbing wave energy, and is made of a fiber material having voids. The fibrous material is a fibrous net formed by layered springs and bonded, and the fibers are preferably made of a polymer material such as plastic. The fiber material may be FRP, FRM, or the like, but is preferably a lightweight material that is not affected by salt in seawater.
A mounting member 4 is formed on the frame member 2. The mounting bracket 4 is one of engagement members for connecting to a structure, and is for fixing the wave absorber 1 to the quay 10. As shown in FIG. 2, a screw portion 21 is formed in a part of the frame member 2. A mounting bracket 4 having a ring formed thereon is screwed into the screw portion 21. Further, an anchor bolt 11 having a ring formed therein is driven into and fixed to the quay 10, and the ring members formed on the anchor bolt 11 and the mounting bracket 4 are connected by the connecting metal fitting 5, so that the wave can be eliminated. The apparatus main body 1 can be fixed to the quay 10.

Next, an example in which the present invention is applied to a marina or the like will be described with reference to FIG. This type of wave absorber has a wave absorber body 1
Is submerged in the water.
An engaging member 41 is attached to an upper end of the main body, and an engaging member 42 is attached to a lower end of the wave canceller main body 1. A pier 6 is formed on the sea surface, and the pier 6 and the wave absorber main body 1 are connected by an engaging member 41. Further, the engagement member 42 formed at the lower end of the wave canceler main body 1 is connected to the anchor 8 buried and fixed at the sea bottom, and the pier is positioned without drifting. In addition, as shown in FIG. 3 (b), a floating body 61 can be attached between the pier 6 and the wave absorber main body 1. Further, the method of fixing to the seabed is not limited to the anchor 8, and the piles 81, 81 and the like can be used.

Next, a description will be given of a slightly modified example. FIG. 4 illustrates a case where the present embodiment is mounted on an iron pile. In the present embodiment, the wave absorber main body 1 is attached to an iron pile 12 driven vertically into the sea bottom. Engagement part 12 on iron pile 12
Engaging members formed on the wave canceling device main body 1 forming the first and the 122
By connecting 41 and 42 with the connecting member 5, respectively,
The wave absorber main body 1 is fixed to the iron pile 12.
In addition, the energy of the incident wave incident on the side of the wave canceling device main body 1 is absorbed by the wave canceling member of the wave canceling device main body 1.

Further, the present invention can be of a type housed in the quay 10 as described in FIG. On the quay 10, a storage part capable of storing the wave-breaking device main body 1 is formed. A fitting hole 22 is formed at the upper end of the frame member 2 of the wave canceling device main body 1 so that the pin member 13 can be inserted and locked. This pin member 13 is one of the locking shaft members. At the position of the quay 10 facing the fitting hole 22 of the wave absorber 1, a through hole 10 is provided.
1 is formed, and the pin member 13 can be inserted therethrough. Therefore, the pin member 13 is inserted into the through hole,
If the tip of 13 is fitted in the fitting hole 22 of the main body 1, the main body 1 can be fixed to the quay. The lower end of the wave canceling device main body 1 has a part of the frame member 2 protruding, and this protruding portion 23 can be engaged with the concave portion 102 of the quay wall 10. The present embodiment configured as described above can provide a wave absorber in which replacement and maintenance of the wave absorber main body 1 are easy without damaging the appearance of the quay 10. Further, since the embodiment does not protrude from the quay wall 10, it does not hinder the navigation of the ship, and has an effect that the shock energy can be absorbed even if the ship collides with the quay wall.

Next, an embodiment in which the present invention is applied to a pool, a pond, a living basin or the like will be described with reference to FIG. 6. Reference numeral 60 denotes a pool in which swimming and the like can be performed. The wave-dissipating device main body 1 is mounted on the side wall of the pool 60. It is desirable that the wave-dissipating member 3 of the wave-dissipating device main body 1 is made of a fiber material having a specific gravity of 1.0 or less, or it is preferable that the fiber material is formed in a hollow shape to generate buoyancy. This is because it is necessary to make the wave absorber main body 1 a floating structure. The buoyancy generating means may employ not only a method in which the fiber material has a hollow structure, but also any method as long as it has a structure in which buoyancy is generated in the main body 1 of the wave canceling device. In particular, the wave-absorbing member 3 can be made of a foam material. The wave absorber main body 1 is formed with four through holes 15. In the present embodiment, four through holes 15, 15,... Are formed, but not limited to four, and an appropriate number can be formed. The through holes 15, 15,...
The first ropes 70, 70 are inserted into the through holes 15, 15 formed in the upper part, and the through holes 15, formed in the lower part, for inserting the 70 and the second ropes 80, 80. The second rope 80, 80 is inserted through 15. Here, the second rope 80 contains a substance having a relatively high specific gravity, such as lead, and is configured to have a higher specific gravity than the first rope. Accordingly, the second ropes 80, 80 generate a relatively large own gravity in the vertically downward direction, so that there is an effect that the wave canceling device main body 1 can be stabilized.
Note that the specific gravity of the second ropes 80, 80 is changed to the first ropes 70, 70.
The means for increasing the specific gravity is not limited to the method of incorporating lead in the second ropes 80, 80, but may be a method of appropriately selecting the material of the ropes. That is, any means for making the specific gravity of the two types of rope different is sufficient. If the first and second ropes 70, 70, 80, 80 configured in this manner are stretched in parallel to the side wall of the pool 60, waves generated by swimmers and the like can be eliminated. Therefore, if the present embodiment is applied to a swimming pool, the swimmer who swims on the outermost course also has a minimum effect on the reflected wave of the wall 60 of the pool 60. The effect is that it can be minimized. It is needless to say that the present embodiment is not limited to a pool, but can be applied to a fishing pond, a boat racetrack, a living garage, a boatyard, and the like.

Next, an embodiment in which the present invention is applied to a tank device will be described. Reference numeral 90 denotes a tank device main body, which can store oil and other liquids. The wave absorber main body 1 is attached to the side wall of the tank device main body 90. At the upper and lower portions of the frame members 2, 2 of the wave canceling device main body 1, mounting fittings 4, 4 are formed so as to be connectable to the tank device main body 90. And, in the tank device main body 90,
Ring engaging members 91 and 91 are formed, and the wave canceling device main body 1 is connected to the tank device main body by connecting the ring engaging members 91 and 91 and the mounting brackets 4 and 4 with the connecting member 5.
Can be fixed at 90. In the present embodiment configured as described above, even if sloshing or the like occurs due to an earthquake or the like and the water surface sways, the wave absorber main body 1 can absorb the energy and attenuate the sway. In the present embodiment, the wave absorber 1 may be provided on the entire inner peripheral wall of the tank device body 90, or the wave absorber 1 may be provided only on a part of the inner periphery. Further, the wave absorber main body 1 with respect to the tank apparatus main body 90
The attachment means is not limited to this embodiment, and any means may be adopted.

The wave-dissipating member 3 provided in the wave-dissipating device main body 1 of the present embodiment can change the void density of this material in the thickness direction. That is, if the gap density of the wave canceling member 3 on the incident wave side is increased (that is, the content of plastic or the like per unit volume is reduced), and the gap density of the wave canceling member 3 is gradually reduced from the incident side ( That is, if the content of plastics or the like per unit volume is increased, it is possible to provide a wave-breaking device with good wave-breaking efficiency. Further, it is desirable that the wave-absorbing member 3 is made of a material having high erosion resistance. The portion of the wave-absorbing member 3 that directly receives the waves has a high degree of erosion and is likely to be clogged. Therefore, it is desirable that the portion be easily replaced.

Further, the frame member constituting the main body 1 of the present embodiment may have any structure. However, if a plurality of pipe members are formed to be orthogonal to each other, a light-weight and high-strength wave canceler is realized. be able to. This embodiment can be used not only in a marina or the like but also as a wave canceling device in a boat racetrack or the like.

Further, the present invention can be applied to an experimental water tank and the like. In particular, since the demand for the strength of the wave canceling device main body 1 for the experimental water tank is relatively low, the wave breaking is performed by cutting out a part of the experimental water tank or attaching the simple frame member 2 to the experimental water tank. A support device for the device main body 1 can also be manufactured.

In the main body 1 of the present embodiment, first, the frame member 2 which is a frame member is arranged, and the adhesive and the wave canceling member 3 are laminated around the frame member 2 to cure the adhesive. Then, a wave absorber in which the frame member 2 and the wave absorber 3 are integrated can be manufactured.

[Effect] The present invention configured as described above provides a wave breaking device for increasing the calmness of a storage pond such as a pool or a pond, wherein the wave breaking member is made of a fiber material having a void. The wave member is formed with a through hole through which a rope for positioning the wave absorber is inserted, so that waves generated by swimmers or the like are absorbed and reflected waves from the side wall of the pool or the like are reduced. There is an effect that can be.

If the wave-absorbing member is made of a fiber material having a specific gravity of 1.0 or less, or if it is provided with a buoyancy generating means such as a hollow portion, the wave-absorbing device main body can have a floating structure, and positioning can be easily performed with a rope. There is an effect that can be.

And since this invention is comprised from the 1st process which arrange | positions a framing member, and the 2nd process which laminates the fiber material containing an adhesive around this framing member, the framing member and the fiber material are comprised. An integrated wave absorber can be manufactured. This integrated wave absorber has an excellent effect that it is easy to move and laying work is simple.
