Description

Seawall Erosion Prevention Block and Construction Method Using the Same

The present invention relates to a coastal erosion prevention block and a construction method using the same, and more particularly, to strengthen the coupling between the locking block is laminated and combined in the vertical and horizontal directions to stably resist wave waves, It can effectively attenuate, fish habitat can be naturally generated, and when the latent blocks are stacked and combined in the vertical and horizontal directions, they can be interlocked in a zigzag as necessary to greatly increase mutual cohesion. In addition, an inflow hole is formed at the foremost side in the area where the subtraction block is constructed to introduce the inflow flow of the sea current into the hollow and guide it in the other direction to reduce direct impact, as well as to the vertical up and down direction adjacent to each other. Can be provided to greatly improve the safety after construction, In addition, if necessary, the current flowing through the current blocking type blocks is connected by connecting the two current blocking blocks adjacent to each other in the horizontal direction. It is invented to be able to attenuate the pressure by or to install the above-described flow-through submerged block between the two submerged blocks arranged to be perpendicular to each other to change the coupling direction of the submerged blocks.

In general, the deeper coastal areas are disturbed by coastal flows caused by coastal facilities such as harbors and portholes, and coastal erosion caused by swelling waves is increasing.

Recently, the coastal erosion problem is expected to result in a continuous phenomenon of sea level rise due to global warming along with nervodal waves. Therefore, it is urgent to prepare a way to avoid the damage.

On the other hand, existing measures to rectify coastal flows using breakwaters are insufficient as measures to prevent damage to sea level rise, and new alternatives are needed. Especially, sand shoreline has a high possibility of coastal erosion, and roads and retaining walls are installed on the coast. Various facilities, such as homes and apartments, are very close to the shoreline, causing disruption of breaking waves and the interruption of sand movement.

Therefore, measures to prevent coastal erosion by mitigating the flow of coastal streams and attenuating aquatic waves should be taken.

Therefore, in the past, "coast erosion prevention block through wave attenuation" has been developed and presented as Korean Patent Application Laid-Open No. 10-2011-0049984, which is formed to be inclined toward the rear in a predetermined section from the front end region of the block to the other end. An inclined surface for guiding the incoming waves; A first arc having a constant depth inward from the end of the inclined surface and a first inclined wall facing upward from the first arc and attenuating the kinetic energy of the rising and returning wave At least one wave attenuating portion; Carbon fiber and aramid fiber fixed to a predetermined thickness on the inclined surface and the surface of the wave damping portion including the first inclined wall to prevent the inclined surface, the first inclined wall and the surface of the wave damping portion from being damaged by waves; It is characterized in that the surface hardness of any one selected from the glass fiber reinforced layer.

However, the coastal erosion prevention block through wave damping with this configuration can be installed on the retaining wall of the shore to prevent the erosion of the retaining wall, but the phenomenon that the sand of the shore is taken out is not attenuated. have.

In addition, the "block for preventing sand loss" proposed as Korean Patent Registration No. 10-1011020 (Registration date 2011.01.19) is a narrow block for sand loss prevention block installed on the shore to prevent the loss of sand. A bottom plate portion having a rectangular plate shape comprising a pair of first sides and a pair of second sides wider than the first side and perpendicular to the first side, and spaced apart from the bottom portion upwardly. A top plate portion having a rectangular plate shape including a third side surface corresponding to the bottom plate portion and a fourth side surface corresponding to the first side surface and a fourth side surface corresponding to the second side surface, and a pair of side plate portions connecting the bottom portion and the top surface portion. Body portion of the rectangular cylindrical shape made; A pair of supporting members extending downward along both edges of the bottom plate; A catching member extending upward along one side edge of the upper plate portion to filter sand in the current flowing from the shore; Blocking member for closing both sides of the body portion; And a filling member filled in the body part and including gravel or sandstone.

However, the sand block prevention block having such a configuration is that when the stack is constructed by stacking the block in the height direction, the fixing force of the upper block is not secured, so that the position is shifted to the wave impact or the posture is twisted, resulting in poor construction stability. There is a problem that the damping effect of the wave is reduced and the sand is taken out.

Accordingly, the present applicant has developed "Development block for preventing artificial erosion combined with artificial reefs and a construction method using the same" and has proposed it as Korean Patent Publication No. 10-1156791.

Among them, the artificial erosion combined erosion prevention block has a hollow penetrating in the width direction, and is located at the bottom of the lower side of the hollow, the front portion of which is placed on one side of the bottom, and the other side of the bottom thereof, facing the front portion. A box-shaped block body formed of a rear portion and an upper portion facing each other located above the bottom portion; A lower front block wing, a lower rear block wing, and an upper front block wing which are located at corners of the bottom and front of the block body and protrude and extend; An upper locking piece having an upper wedge groove on one side of an upper surface of the block body; A wedge engaging piece having the same shape as protruding downward from the bottom of the bottom of the block body and corresponding to the upper wedge groove; And a block locking jaw formed at a portion where an inner surface of the lower rear block blade meets a bottom surface of the bottom portion.

In addition, the front portion is formed with a single vortex curved surface for dispersing the inflow of the current flowing into the coast from the sea side up and down, and the front portion is vertically symmetrical to disperse the inflow of the current flowing into the coast from the sea side up and down An upper vortex curved surface and a lower vortex curved surface forming a vortex are formed, and a through hole communicating with a hollow is formed in the upper surface portion.

In addition, the upper surface portion has a pair of male and female concave grooves and concave projections having contours of the same shape on both end surfaces in the width direction, and at least one sea current for introducing the current flowing in blue into the front portion in the hollow Inlet hole is formed.

In addition, in the construction method using the artificial erosion combined coastal erosion prevention block, the artificial erosion combined coastal erosion prevention block has the front side facing the sea side and is arranged adjacent to the sea side of the coast in the width direction and the width direction so that the first stage is submerged. Construct a block layer; Stacking the second block or more of the potential block layers in consideration of the height of the installed sea surface by arranging the same artificial reef combined coastal erosion prevention block on the upper portion of the first layer of the potential block layer; At the forefront side of each stage of the interlocking block layer, an artificial reef combined coastal erosion prevention interlock having a current inflow hole is disposed, and the current inflow hole is directed toward the sea side.

However, the artificial reef combined coastal erosion prevention block made of such a configuration and steps, and the construction method using the same, the first block by placing the blocks in the width direction and the width direction adjacent to the sea side of the coast side facing the seaside first step When laying the second block or more of the second layer in consideration of the height of the installation sea level by placing the same artificial reef combined coastal erosion prevention block blocks to the upper portion of the first layer of the block layer after the construction of the block layer As it has a simple stacking structure without a separate coupling structure, the bonding force in the vertical up and down directions is very weak, and the currents do not flow in the vertical up and down directions adjacent to each other, thereby ensuring safety for the current after construction. Not only that, there is a problem that the wave attenuation effect falls.

In addition, in all potential blocks, a single vortex curved surface or upper and lower vortex curved surfaces forming a vertical vortex or vertical symmetry to disperse the inflow of the sea current flowing from the sea side to the shore is formed on the front side. It can't be dispersed and alleviated, and only part of the upper part has a hole in communication with the hollow. In particular, it is possible to combine each of the potential blocks only in a straight direction, so that the direction of engagement in the perpendicular direction of the potential blocks cannot be changed to efficiently mitigate the flow of coastal streams approaching from various directions. Can not effectively attenuate, limiting the prevention of coastal erosion There point.

In the above, the hollow 111 having a shape that penetrates both sides of the current-flow reflective submerged block body 11 is shown to have a rectangular cross-sectional shape in the drawing, but is not limited thereto. The hollow 111 may be selectively filled with rocks, gravel, sandstone, etc. for the purpose of increasing the weight of the current-flow reflective submerged block 10.

Meanwhile, the lower front and

rear block wings

12 and 13 have protruding shapes extending from the edges of the sea plate 113 and the front and

rear plates

114 and 115 of the current-flow reflective submerged block body 11. The lower front and

rear block wings

12 and 13 penetrate into the sea bottom when the current reflection reflective block 10 is located at the bottom layer, thereby stabilizing the installation position of the current reflection reflective lock block 10. Let's do it.

In addition, when the current reflection reflective blocks 10 are stacked in the height direction as shown in FIG. 5 (a) (b), the lower front and

rear block wings

12 and 13 have a lower current reflection reflective block. (10) is adhered on.

In addition, the bar coupling protrusion 14 is a pair of two coupling grooves 14a having a predetermined width toward both the front and the rear sides of the bottom surface of the bottom plate 113 of the current-flow reflective submerged block body 11. And protrude integrally therebetween, respectively, on the

top plates

112 and 212 of the lock block body when stacked on top of the other current reflecting lock block body 11 or the flow through lock block body 21. Protrudingly formed between the fasteners (15, 25) of the pyramid-shaped to be described later to be sandwiched in the form of the locking blocks of the present invention to be laminated in the up and down direction to maintain a stable or fixed form mutually Perform.

In addition, the pyramid-shaped fixture (15) is provided with a coupling piece (15a) fitted in the coupling groove (14a) formed between the bar-shaped coupling protrusion 14 on the upper surface and the upper plate of the current-flow reflective locking block body (11) Produced integrally at a predetermined interval (in each center in the state divided into four at the upper surface) at (112), the other current-flow reflective locking block body 11 or the current passing through the locking block body 21 is vertical To be coupled to the upper portion, or the different current-reflective locking block bodies 11 or the current-passing locking block bodies 21 are selectively coupled to each other in front, rear, left, and right directions (ie, in a zigzag fashion). To be combined).

That is, the pyramid-shaped fixtures 15 are installed in two or more stages by zigzag arrangement and stacking of the current-flow reflective locking blocks 10 or the current-flowing locking blocks 20 to be described later. The upper and lower surfaces of the adjacent current reflection type blocking block 10 or the current passing type locking block 20 are engaged with each other by 1/2 or 1/4 as shown in FIGS. 5 (a) (b) to 8, respectively. To perform the function.

In addition, the bar-shaped coupling protrusion 14 and the pyramid-shaped fixture 15 are combined with the current-flow reflective locking blocks 10 or the current-flowing locking blocks 20 that are coupled in a stacked manner. In addition to the function to maintain the form of mutually stable, as well as the role of preventing the current-flow reflective locking block 10 or the current-flow locking block 20 of the upper end by the wave force of the sea pushing from the sea side to the coast side. Will also be performed.

At this time, the formation direction of the pyramidal fixture 15 is formed as necessary to have a 90-degree angle to each other as shown in Fig. 3 (a) (b) in order to correspond to the installation direction of the current-flow reflective locking blocks 10. Can be.

In addition, the pair of male and female concave grooves 16 and the concave protrusions 17 are formed to have a contour of a shape opposite to each other in the vertical direction on both sides of the current-flow reflective locking block body 11 and adjacent to each other. Both sides of the current reflection type locking block body 11 or the current passing through the locking block body 21 to perform the function to be coupled in a close contact with each other.

On the other hand, in order to reduce the wave energy by dispersing the inflow of the sea current flowing from the sea side to the coast in one direction or up and down, it is formed as an arc-shaped single vortex surface 116a, as shown in Fig. 3 (c), or Figs. 1 and 2 And the upper vortex surface 116b and the lower vortex surface 116c, which form upper and lower line symmetry to have an arc shape or a three-dimensional parabolic curve having the same radius of curvature as shown in FIG. 3 (a) (b), At least one current inlet hole 114a having any one of rectangular, hexagonal, and octagonal shapes, including a circular shape, is included in the front plate 114 of the current-flow reflective submerged block body 11 to be installed therein. By providing a portion of the wave current flowing in the blue can be introduced into the hollow 111 through the current inlet hole 114a formed in the front plate 114, it can greatly reduce the impact from the wave energy.

In addition, in the present invention, the upper and

rear plates

114 and 115 of the current reflecting type locking block body 11 having the single vortex curved surface 116a or the upper vortex curved surface 116b and the lower vortex curved surface 116c are provided. When the current reflection reflective blocks 10 are stacked in two or more stages in the vertical direction by forming the current flow distribution grooves 18 each having a semicircular flat section at a predetermined interval in the vertical direction from the bottom, The two current distribution grooves 18 are mutually coupled to the front and rear contact portions of the two current reflection reflective locking blocks 10 adjacent to each other in the rear to form a current flow hole having a circular flat cross section.

In addition, in the present invention, the through-hole 112a communicating with the hollow 111 is further formed in the central portion of the upper plate 112 of the current-flow reflective submerged block body 11.

Thus, between the front and

rear plates

A part of the currents introduced into the space portion formed in the is distributed in the vertical up and down direction through the current flow distribution groove 18, a part of the currents introduced into the hollow 111 of the current reflection reflective block body 11 Since the upper plate 112 is distributed in the vertical up and down direction through the through hole 112a formed in the center, the direct impact due to the current can be greatly reduced, so safety after construction is excellent.

Meanwhile, an air gap is formed between the hollow 111 of the current reflection type subtraction block body 11 and the neighboring current reflection type subtraction block 10 to form artificial reefs, and the artificial reefs are formed of the currents generated by waves. Since it does not receive inflows directly, it favors the habitat of fish and fish.

On the other hand, another embodiment of the present invention erosion block for coastal erosion, as shown in Fig. 4 (a) (b), the current passing through the locking block body 21 in the form of a rectangular box 21 and the lower side of the side block wings 22, bar type Formed by the current-flow locking block 20 including the engaging projections 24, pyramid-shaped fixtures 25, uneven coupling grooves 28 and coupling projections 29 as the main technical components, In order to avoid repeated descriptions, detailed descriptions of specific operations and functions of some components having the same configuration and function as the current-flow reflective subtraction block 10 will be omitted.

At this time, in the current passage type locking block 20, the current passage type locking block body 21 in the form of a rectangular box hollow (211) is formed so that the front, rear surface penetrates, the upper and lower parts of the hollow 211 The upper plate 212 and the bottom plate 213 is integrally formed, and both side ends of the upper plate 212 and the bottom plate 213 have a form in which both side plates 214 are integrally formed, or the current If necessary, both sides of the passage-type locking block body 21 may further include a hollow 211 formed to penetrate the front and rear surfaces and a current flow passage hole 214a to penetrate.

That is, the current flowing through the locking block body 21 of the above-mentioned current reflection reflective block body formed with a hollow 111 that is blocked by the front,

rear plate

114, 115 and penetrated to both sides basically. Unlike (11), the hollow 211 is formed to penetrate the front and rear, and both sides have a form blocked by the side plates 214, so that the currents flowing from the sea side to the coast side penetrate the front and rear sides. The air flow passage hole 214a penetrates the hollow 211 and is further formed on both sides of the current passage-type submerged block body 21 so as to be directly passed through the hollow 211 having the same or all four surfaces thereof. By installing the current passing through the locking block 20 between the current reflecting locking block 10 or the "A" shaped seawater passing through the current-flow reflective locking block 10 installed in the corner of the connecting portion of the locking block The current flow when the block 20 is installed The hollow 111 formed in the sand-type submerged block 10 mutually interacts with the hollow 211 of the current-flow-type submerged block 20 through the current flow through holes 214a formed on both sides of the current-flow submerged block body 21. To be connected.

Therefore, the sea current flowing from the sea side to the coast side passes directly through the hollow 211 having a form penetrating the front and rear of the current flow-type submerged block 20, the hollow formed in the current-reflective submerged block 10 ( The current flowing through 111 is reflected by the current through the current through holes 214a formed on both sides of the current passing through the locking block body 21 and the hollow 211 of the current passing through the locking block 20. It can be mutually circulated to the hollow 111 side of the mold potential block 10.

In addition, the lower both side block blades 22 are positioned at the edges of the bottom plate 213 and both side plates 214 of the current flow through the locking block body 21 has a protruding form, the bar coupling projection ( 24 is protruded from the front and rear of the bottom plate 213 bottom of the bottom of the current flow type locking block body 21 in both directions in between the grooves (a) of a certain width between the other current flow locking block body (21). Or between the pyramid-shaped

fixtures

25 and 15 protruding from the

upper plates

212 and 112 of the current-flow reflective submerged block body 11, respectively.

In addition, the pyramid-shaped fixture (25) has a coupling piece (25a) is fitted to the coupling groove (24a) formed between the bar-shaped coupling protrusion 24 on the upper surface and the upper plate of the current-flow locking block body 21 Protruding integrally formed at a predetermined interval at 212, the other current passing through the locking block body 21 or the current reflecting locking block body 11 is coupled to the top or different current passing through the locking block body (21) Alternatively, the current reflection latent block bodies 11 may be selectively coupled to each other in front, rear, left and right directions.

In addition, the uneven coupling groove 28 and the engaging projection 29 is the current reflection reflective type so as to be mutually coupled with both sides of the current-flow reflective locking block body 11 or the current passing through the locking block body 21 adjacent to each other. On both sides of the potential block body 11 has a contour of the shape opposed to each other in the vertical direction and has a form each formed in pairs.

At this time, when the bottom of the uneven coupling groove 28 formed on both sides of the current flow through the locking block body 21 in the open form as it is, the current-flow reflective locking block 10 and the current flowing through the locking block ( 20 are combined and stacked on both sides and the upper and lower sides, the

concave protrusions

17 and 27 formed in the current-flow reflective locking block body 11 or the flow-through locking block body 21 are coupled to the coupling recess. There is a fear of falling through (28).

Therefore, in the present invention, the bottom of the uneven coupling groove 28 and the coupling protrusion 29 formed on both sides of the current passage passing locking block body 21 is the current reflection reflective locking block body 11 or the current passing locking block. A support jaw 30 was further formed to support the bottom of the indentation protrusions 17 and 27 formed in the body 21.

In addition, unlike the above-described current reflection type subtraction block 10 in the current passage-type submerged block 20, in the vertical direction from the front, rear surface of the current passage-type subtraction block body 21 adjacent to each other Fig. And a pair of male and female recessed grooves 26 to be coupled to both side surfaces of the current-flow locking block body 21 or the current-reflecting locking block body 11 arranged in the shape of "a" as shown in FIG. 8. ) And the concave protrusion 27 have a contour of a shape facing each other and have a further formed shape.

In addition, in the center of the upper plate 212 of the current flow passage type blocking block body 21, as in the current blocking type blocking block 10, a portion of the currents introduced into the hollow 211 can be vertically and vertically distributed. Through holes 212a communicating with the hollow 211 were formed.

On the other hand, the construction method using the coastal erosion prevention block, the construction method using only the current reflection type subtraction block 10, the current reflection type subtraction block 10 and the current passing through the subtraction block ( 20) can be presented in a way of mixing and constructing properly.

First, the construction method using only the current-flow reflective subtraction blocks 10 as shown in FIG. 5 (a) (b), firstly faces the front side of the current-reflective subtraction blocks 10 toward the sea side. The first stage current reflection reflective block layer is constructed by arranging the same or zigzag adjacently in the width direction, the width direction, and the front and rear directions on the sea side of the coast.

Subsequently, another current-flow reflective blocking block 10 is stacked on the first stage of the current reflective reflective block layer in the same or zigzag manner in consideration of the height of the sea surface. However, the front surface side of the current reflective reflective block layer of each stage is arranged on the front plate 114, the current reflecting reflective locking block 10 having the current inlet hole (114a) part of the current wave flowing from the sea side is the front plate It is constructed to be introduced into the hollow 111 side through the current flow inlet hole (114a) of (114).

In addition, the method of properly mixing the current-flow reflective submerged blocks 10 and the current-flow submerged submerged block 20 presented above is divided into three types described below.

First of all, as shown in FIG. 6 (a) (b), the first stage current reflecting type latent blocking layer is constructed using the current reflecting type blocking blocks 10 or the current reflecting type is formed at a second level or more. When stacking the latent blocking layer, if necessary, the current passing latent blocking blocks 20 may be disposed instead of some of the current reflecting latent blocking blocks 10. The hollow 211 formed to penetrate is arranged in the form penetrating the sea side and the shore.

Therefore, in the coastal erosion prevention block having a state in which some of the currents coming from the sea side stacked in the form of a wall to the front and rear through the current through the flow-type submerged block 20 provided with a hollow 211 so that the coast at the seaside Since it passes directly to the side, it is possible to greatly reduce the pressure due to the current of the shoulders applied to the current-flow reflective submerged blocks 10, thereby further securing stability after construction.

Secondly, as shown in FIG. 7, the first stage current reflecting latent block layer is constructed using the current reflecting latent blocking blocks 10, and then the current reflecting latent blocking layer is laminated to the second stage or more. At this time, if necessary, the current-reflective locking blocks 10 may be arranged in a "a" shape, but the current flowing through the locking block 20 may be disposed at a corner portion that is bent in a "a" shape. The current-reflective locking blocks 10 arranged in the shape of a child are configured to have a form in which they are integrally coupled to each other by the current-flowing locking blocks 20.

In this way, the above-described current passage-type locking block 20 is installed at the corners of the current-reflective locking blocks 10 arranged to be perpendicular to each other, thereby switching the coupling direction of the current-flowing reflective locking blocks 10 to the perpendicular direction. Not only can it more effectively mitigate the flow of the currents coming from various directions, but it can also effectively reduce the waves, as well as significantly prevent coastal erosion.

Third, as illustrated in FIG. 8, the current reflection reflective block 10 arranged in the shape of “a” is interconnected using the current passing through the blocking block 20 to be stacked in a second or more stage. In construction, if necessary, instead of some of the current reflective reflective blocks 10, the current flowing through the locking blocks 20 are arranged so that a part of the currents pushed in various directions from the sea side is stacked in the form of a “a” shaped wall. In the composite method of passing through the current through the flow-type locking block 20 is provided with a hollow 211 so that the front and rear of the coastal erosion prevention block having a state to pass, toward the shore, the current of the wave approaching from various directions In addition to mitigating the flow of water as effectively as possible, it is also possible to attenuate the waves more effectively, thereby maximizing the prevention of coastal erosion.

At this time, both sides of the current flow through the locking block body 21, the hollow 211 and the current passing through holes 214a are formed so that all four surfaces have a form to pass through as described above, Installing the current-flow locking block 20 between the locking blocks 10, or in the corner of the connection portion of the current-flow reflective locking block 10 is installed in the form of "a" flow-through locking block 20 When it is installed, the hollow 111 formed in the current reflection reflective block 10 through the current flow through the hole (214a) formed on both sides of the current flow through the locking block body 21 flow-through locking block 20 It will have a form interconnected with the hollow 211.

Therefore, the sea current flowing from the sea side to the coast side passes directly through the hollow 211 having a form penetrating the front and rear of the current flow-type submerged block 20, the hollow formed in the current-reflective submerged block 10 ( The current flowing through 111 is further directed to the current through the air passages 214a and the hollows 211 of the current passing through the locking block 20 formed in both sides of the current passing through the locking block body 21. Smoothly flows to the hollow 111 side of the reflective submerged block 10.
