Description

{Coastal erosion Coastal Structures double proof}

More specifically, a plurality of submerged blocks having a predetermined shape and a predetermined volume on the sea floor of a sea a certain distance away from the coast are stacked so as to have a predetermined length, width and height A plurality of floats formed to have a predetermined shape and to form a horizontal block having a predetermined volume, and a plurality of floats formed to have a predetermined shape, A wave absorbing revetment is formed by providing a plurality of file guiders at a predetermined interval between the corners and the outer corners, And is coupled to the file so as to be lifted and lowered along the water surface, so that the cost of the submerged block (Ie, wave power) incident on the shore can be doubly canceled by the submerged block and the floating seawater (ie, the wave and waves To effectively prevent the erosion of the coast to the greatest possible extent.

Coastal erosion is expected to continue to occur as sea levels rise and storm intensity increases are expected to continue with the increase of wavy waves due to global climate change, including around the Korean Peninsula.

In addition, coastal areas such as harbors and coastal areas are experiencing unexpected coastal erosion due to coastal erosion caused by coastal currents and coastal erosion, And measures should be taken to prevent them.

Especially, coasts are being eroded by long - wave incident waves, and human and property damage due to loss of the coast is increasing.

In order to reduce these damages, measures are being taken to restore the shoreline through measures such as retreating major facilities along the shoreline and creating an artificial Yangbian and vegetation environment.

In order to prevent erosion of the coastline as described above, a breakwater structure is installed on the coast, and the wave energy toward the coast is reduced through the breakwater structure to create a wide calm water area, efficiently protect the coastline have.

However, a high proportion of wave energy is reflected in the breakwater structure to form a double wave, which causes serious erosion, and breakwater structure collapses.

Therefore, in order to reduce the above-described reflected waves, a multi-piercing structure is conventionally developed and installed on the shore.

The conventional multi-structure piercing structure has the effect of simultaneously reducing the reflection and transmission wave height while adjusting the phase difference of the scattered waves through a plurality of the porous plates installed vertically along the sea surface.

However, although the above-mentioned vertical-hole structure showed effective sofa performance for short-period waves, it was inefficient for relatively long-period waves. This allowed a considerable space in the water depth direction, So that it is transmitted through the antenna.

In addition, in some coasts, in order to preserve the landscape of the coast and secure the view of the coast, the coastal sand is prevented from being lost by the waves, The blocks are stacked so as to have a predetermined width (for example, 80 to 100 m), a width (for example, 30 to 50 m) and a height (determined by maximum water depth and wave power of the area) A submarine structure is provided to fix some of the blocks to a sea floor using a file having a predetermined shape to prevent the submerged blocks from flowing into the wave.

However, since such a submerged block is very large in size, it is difficult to manufacture and transport it, resulting in a large production cost and transportation cost. In addition, since each submerged block is placed on the sea floor in the water, It is expensive and time consuming. In particular, in order to prevent the loss of the waves of the large waves in the water and the loss of the sand that is pushed out from the shore, it is necessary not only to install at a high height but also to install a wide width.

In addition, the submerged blocks installed on the seafloor have the function of attenuating only the energy of the waves transmitted through the water, but can not cancel out the waves transmitted along the water surface.

On the other hand, the Hangzhou wave in the open sea area gradually decreases in energy as it propagates from the generation point to the periphery and eventually disappears, but there is no problem. However, as the width of the channel is approaching or approaching to the coast, Is shallow, the wave propagates to the shore, causing deformation such as refraction, deformation, reflection, and diffraction.

Since it is difficult to protect marine leisure facilities such as fish farms and marinas from Hangzhou waves or waves generated by ships as described above, or to install wave breakers in order to prevent the surrounding waves when working in the marine environment, Floating sofa that can be used as a new sofa system is attracting much attention.

However, such a buoyant type sofa wave, that is, the float, generates a wave having a phase different from the phase of the wave due to the fluctuation due to the incident wave, so that the wave height? T of the transmission wave can be lowered. When the wave length (λ) of the wave is significantly larger than the width of the sofa (usually less than 1/4 of the wavelength λ of the sofa), the sofa is simply raised or lowered by the water level, .

Therefore, there is a problem in that the sofa performance can not be exerted properly in the deep sea depth where the wave of the long wavelength forms the mainstream. As described above, in order to improve the performance of the sofa, the width of the sofa should be at least 1/4 of the wavelength, but there is a limit to increase the width of the float.

In addition, floating breakwaters have been developed and used in some places. Such floating breakwaters reduce wave energy by installing a sofa plate having a soapy ball in the wave direction of the float, but the wave or wave has a predetermined wavelength Therefore, there is a problem that it is difficult to expect a damping effect of a large energy because the duration for reducing the wave energy passing through the sofa formed on the sofa plate is short.

In addition, the submerged block 1 includes a permeable submerged block having a fish-mouth function.

The effect of the coastal erosion prevention structure of the present invention constructed as described above will be described below.

First, as shown in Figs. 1 to 4, the coastal erosion-resistant double coast type coastal structure of the present invention comprises a plurality of submerged blocks 1, a plurality of piles 2, a floating sofa 3, The energy (i.e., wave power) of waves incident on the shore is formed of a plurality of file guiders 4 and a plurality of flowable coupling means 5 through the submerged blocks 1 and the floating sofa 3 The main technical factor is to be able to offset the seawater and sea water surface in two ways.

At this time, the plurality of submerged blocks 1 are formed using concrete, reinforcing bars or various wastes so as to have a predetermined shape and volume. The submerged block 1 may include a permeable submerged block having a fish- Any known type may be used.

Such a submerged block 1 functions to attenuate the wave transmitted through the water by laminating the submerged block 1 such that the submerged block 1 has a predetermined length, width and height on the sea floor of a sea a certain distance from the coast. In the present invention, It is possible to attenuate the same wave twice by using the floating type sofa 3, which will be described later, including the block 1. Thus, compared with the case where the wave is canceled by using only the conventional submerged block, (For example, 10 to 15 m) smaller than the conventional width (for example, 30 to 50 m).

Therefore, since the use of the relatively high-priced submerged block (1) compared to the production cost of the floating soap preparation (3) can be minimized, the installation cost of coastal structures installed to prevent coastal erosion can be greatly reduced.

In addition, the plurality of files 2 basically fix some of the submerged blocks 1 to the seafloor so as to prevent the submerged blocks 1 from flowing due to a wave or the like, It is possible to have any shape and form including the file which has been patented by the present applicant and filed as 10-1091585 (registered on December 02, 2011).

However, in the present invention, in order to allow the floating file sofa 3 to move up and down along the file 2 in response to a change in the height of the water surface, a part of the file 2 is used , And the length of some files among the files (2) is extended and extended to the sea surface.

The float type sofa 3 is provided with a plurality of float 30 provided at four corners of the main body 31 having a predetermined shape and each having a flowable coupling means engaging piece 32, (For example, an area equivalent to the planar area of the submerged block 1 having a stacked state) in the form of a horizontal block Molded.

The floating sofa 3 is coupled to the files 2 in a state of being coupled to a plurality of file guiders 4 to be described later so as to be able to move up and down through the file guiders 4, And functions to attenuate the residual wave force acting on the upper portion without being canceled by the submerged blocks 1 including the wave power formed along the wave block.

Therefore, since the energy (i.e., wave power) of the wave incident on the shore can be canceled in a double manner through the above-mentioned submerged block 1 and the floating sofa 3, the wave and wave can be effectively quenched Therefore, it is possible to effectively prevent coastal erosion.

The float 30, which is used in units of units for forming the float type sofa pad 3, is made of a synthetic resin injection-molded body 31 having a rectangular parallelepiped shape having a predetermined volume as shown in FIG. 5 (32) having an elongated iron plate shape in which a hinge passage hole (321) is perforated at the end in the outward direction at the four corners or the hinge ball (322) is integrally formed as shown in Figure 12 And has a protruded shape.

The main body 31 of the float 30 can be floated by the buoyant force of the seawater and can be smoothly offset by the use of a synthetic resin so as to have a hollow enclosed form as shown in FIG. 6 (a) Alternatively, it may be molded into a straight hexagonal body filled with a synthetic resin having a low specific gravity as shown in Fig. 6 (b).

A portion of the seawater impinged on the bottom of the float 30 is formed in the seawater passage 33 by vertically forming a seawater passage hole 33 in the vertical direction from the center of the float 30, ), And then repeats the process of going down again, thereby further reducing the wave power.

The end portion of the body 31 of the float 30 which is integrally molded with the hinge passage hole 321 or the hinge passage hole 322 is protruded outward through four corners In this case, if an impact is applied to the outside from the outside for a long period of time, there is a risk of separation from the main body 31. Therefore, the hinge holes 321 are formed at the respective ends of the steel plates or the hinge balls 322 are integrally formed as shown in Figs. 5A and 5B, The hinge hole 321 is pierced or the hinge ball 322 is formed integrally with only a portion of the end portion, that is, only the flowable coupling means engagement piece 32 having an elongated iron plate shape And it is preferable to protrude outwardly through an edge.

7, the plurality of file guides 4 may be formed by drilling a hinge passage hole 421 at an outer end thereof at four corners, or by forming a hinge hole 422 of an iron plate shape As shown in Figs. 3, 4, 10, and 14, each of the corner portions of the floating soap agent 3 and the connecting portion 42 of the floatable sofa 3 are integrally formed, (3) via flowable coupling means (5) with a predetermined distance along the outer side of the float (3).

Such a file guider 4 has a shape that is fitted to the outside of the piles 2 which are extended and extended to the sea level and is formed to extend in the vertical direction along the piles 2 together with the floating sofa 3, The float type sofa 3 functions to automatically rise and fall along the pile 2 in response to a change in the height of the sea level (i.e., corresponding to the change in the size and height of the wave) do.

The frame body 41 of the file guider 4 is formed to have a rectangular ring shape by using a synthetic resin or aluminum having a low specific gravity and a strong strength. At the outer side of the four corners of the frame body 41, And the hinge hole 421 is pierced as shown in FIG. 13 or the iron plate-shaped flowable coupling means coupling piece 42 integrally formed with the hinge ball 422 as shown in FIG.

At this time, when the frame 41 of the file guider 4 is simply formed in such a form that the file 2 can be sufficiently inserted, the file of the file guider 4, together with the floating sofa 3, A large frictional force is generated between the inner surface of the frame 41 of the file guider 4 and the outer surface of the pile 2 when the guider 4 moves up and down along the outer surface of the pile 2, The upward and downward movements of the file guider 4 including the obstacle 3 may not be accurately performed in response to a change in the height of the sea surface.

Therefore, in the present invention, the rollers 43 are rotatably installed inside four corners of the frame 41 of the file guider 4 so that the file guiders 4 can be rotated together with the floating sofa 3 The frictional force that may occur between the outer surface of the pile 2 and the inner surface of the frame 41 can be minimized when the pile 2 is raised or lowered along the pile 2 corresponding to the height of the sea surface, , The file gauge 4 is moved up and down along the file 2 corresponding to the change in the height of the sea surface.

On the other hand, the flowable coupling means 5 has a function of fluidically coupling the edge portions of the float 30 and the pile guides 4 of the floating sofa 3, The end shapes of the flowable coupling means engaging pieces 32 and 42 provided at the four corners of the float 30 and the pile guider 4 421) are perforated or the balls 322, 422 for hinges are formed integrally), different components can be presented.

In this embodiment, when the hinge passage holes 321 and 421 are drilled in the end portions of the flowable coupling means 32 and 42, the rivet 51 or 8 And the hinge balls 322 and 422 are provided at the ends of the flowable coupling means 32 and 42. The hinge balls 322 and 422 may be hinged to each other through bolts 52 and nuts 53, 10, 11, and 14, a pair of upper and lower fixing plates 54 having a shape in which a ball coupling hole 541 for a hinge is perforated are formed at four corners, respectively, And a plurality of bolts 52 and nuts 53 for fixing the fixing plate 54 integrally with each other.

When one of the flowable coupling means 5 is used to couple the float 30 of the floating sofa 3 to the pile guides 4, And the hinge passage holes 321 and 421 of the flowable coupling means 32 and 42 provided so as to protrude outward from the respective flowable coupling means 32 and 42 are aligned with each other so as to be adjacent to each other, The rivet 51 which is the flowable coupling means 5 is inserted through the hinge passage holes 321 and 421 formed in the coupling means coupling portions 32 and 42 and then the rivet 51 is inserted or the bolt is inserted, The float 30 and the file guider 4, which are adjacent to each other, have a form in which they are integrally combined as shown in FIGS.

At this time, the length of the rivet 51 and the bolt 52 used as the flowable type coupling means 5 is the same as the length of the uppermost end of the bolt 52 having four or two overlapping shapes as shown in Figs. 8 (a) Or at the bottom of the flowable coupling means coupling piece 32, 42, which is located at the lower end of the flowable coupling means 32, 42.

That is to say, the floating fluid coupling means 32 and 42 of the float 30 and the pile guiders 4 arranged adjacently to each other are respectively connected to the rivet 51 or the bolt 52 and the nut 53 When the flowable coupling means (32) and (42) located at the uppermost or lowermost position are integrally coupled to each other through the long flowable coupling means 8A and 8B, the upper portion and the lower portion of the body 5 are protruded by a predetermined height, so that the loose coupling state is maintained.

Therefore, the rivets 51 or the bolts 52 used as the flowable coupling means 5, including the plurality of float 30 constituting the floating sofa 3, The wave float 30 and the pile guider 4 are deformed when the wave and the wave are applied along the water surface or are applied to the bottom in the water, Since the waves are moved in different directions corresponding to the direction of the wave and the waves, the waves and waves can be canceled more effectively, thereby effectively preventing coast erosion.

When the float 30 of the float type sofa 3 and the pile guides 4 are to be coupled to each other by using another embodiment of the flowable type coupling means 5, The hinge balls 322 and 422 of the flowable coupling means 32 and 42 provided so as to protrude outward from the corner portion are arranged close to each other in four chambers adjacent to each other, A pair of fixing plates 54 having holes for hinge balls 541 are formed on the upper and lower surfaces of the hinge balls 322 and 422 to form upper and lower portions of the hinge balls 322 and 422, The pair of fixing plates 54 are integrally fixed to each other by using the plurality of bolts 52 and the nuts 53 in a state in which a part of the fixing plates 54 is fitted in the hinge ball fixing holes 541 of the fixing plate 54, 10, 11, and 14, respectively.

Therefore, the plurality of float 30 and the pile guiders 4 are inserted into the hinge ball engagement holes 541 of the fixing plate 54 and the hinges of the fluidizable engagement means engagement pieces 32, When the wave and the wave are applied along the water surface or are applied to the bottom surface in water as shown in the virtual line of Fig. 11 with the balls 322 and 422 for use as the axis as the axis, The float 30 and the file guider 4 are moved in different directions corresponding to the directions of the waves and wave applied by the float 30 and the wave guider 4, respectively, thereby canceling the waves and waves more effectively. It can be prevented more effectively.

On the other hand, when the file 2 is simply installed in the form of a column, when a tidal wave occurs and the wave height is very high, the file guiders 4, which are coupled to the file 2 so as to be movable up and down, There is a possibility that the floating sofa 3 itself is disappeared by being disengaged through the upper end of the file 2.

Accordingly, in the present invention, even if a very high wave is pushed due to a tidal wave or the like by providing a file guider departure prevention cap 21 having a predetermined shape at the upper end of the file 2, the file guiders 4 It is possible to completely prevent the floating sofa 3 having the combined state from being separated from the upper end of the pile 2 and to prevent the damage of the floating sofa 3 due to natural disasters or the like, It can be prevented in advance.

Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Which will be apparent to those skilled in the art.
