DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a revetment block applicable to low-water revetment and embankment work, and more particularly to a revetment block suitable for the construction of a multi-natural river for preserving and creating natural waterfront in a river. It relates to a concrete revetment block that can be made.

[0002]

2. Description of the Related Art In recent years, along with increasing interest in environmental issues, measures taking into account moisture and room have become increasingly important as a trend in social capital development. In other words, in civil engineering work, policies that emphasize the preservation of the natural environment and landscape tend to increase in the future, and restoration of natural vegetation, ecosystem preservation,
Various technologies for creating a new green space are proposed. In the case of rivers, technologies aiming at “creation of multi-natural rivers” have been proposed and tested in order to coexist with nature and to provide a place for relaxation to local residents.

[0003] Here, "creation of a multi-natural river" means that a waterfront space (waterfront) of a river is regarded as a core of a habitat (biotope or habitat) for inhabiting various organisms, and is as natural as possible. The aim is to create a (near natural) river and create a waterside rich in nature. In the “creation of multi-natural rivers”, utilizing the natural dynamism of the rivers themselves, assuming the erosion and deposition of river banks and river beds, grasping the natural environment and ecosystem of the rivers, and preserving and creating them It is necessary to plan.

On the other hand, rivers in Japan generally have large fluctuations in flow conditions, unstable flow paths, and large fluctuations in riverbeds.
About half of the population and about 70% of the total assets are concentrated in the river inundation area, which occupies 10% of the national land and 1/3 of the flat land. Therefore, when promoting the “creation of multi-natural rivers”, rivers that can ensure sufficient flood control safety under various constraints, taking into account the above-mentioned natural and social characteristics of Japan It is necessary to develop a construction method.

[0005] In particular, the revetment comprising dike revetment, high-water revetment, low-water revetment, foundation work, shoring work, etc. is one of the main flood control works, and is used for the preservation and creation of the ecosystem and landscape at the installation site. Considered structure is required. Of the revetments, low-water revetments and shoring works are located along the river banks (borders) and are closely related to waterfront ecosystems and landscapes. On the other hand, the revetment needs to have a function of preventing erosion of embankments and river banks, and has a stable structure against flowing water. Therefore, at present, as a revetment work, the creation of a multi-natural river using a so-called traditional river construction method such as rubble, yanagi, woodwork squatting and sloping squatting is being reviewed.

[0006]

The above-mentioned traditional river construction method has advantages such as high adaptability to construction sites, adaptability to ground changes after construction, and a favorable effect on river creatures. . Therefore, many examples of the application of the traditional river construction method to "creation of a natural river" have been reported as a construction method that can achieve both the function of creating and maintaining biotopes and the function of flood control required for revetment. On the other hand, the traditional river construction method, for example, in the case of willow branch construction, willow scent, pile, fence, earth and sand, gravel,
Logs and stones are used in the case of woodwork sinks. That is, the traditional river construction method mainly uses natural materials such as plants, wood, and stones as materials. At the site, they work on assembling wood into frames or fences, and filling them with stones. Therefore, the conventional traditional river construction method requires considerable labor and time for on-site work due to on-site construction.
In addition, there is also a problem that while skilled workers are required because construction on site requires considerable skill, skilled workers are insufficient. Further, securing and stable supply of the material becomes a problem, and the material cost increases.

[0007] In particular, in a woodwork sunk floor used as a rock consolidation work, wood as a constituent material is hardly corroded when it is always below the water surface, but is always exposed above the water surface (in the air) due to a decrease in water level due to riverbed fluctuation. If you decide to
On the other hand, when water is changed alternately in the water and in the air due to fluctuations in the water level caused by weather fluctuations, etc., the corrosion proceeds significantly. As a result, the function as a consolidation work may be impaired in terms of strength and durability.

Therefore, the present invention improves the workability in the field, can stably supply the material, can reduce the material cost, and has functions such as strength and durability due to corrosion. It is an object of the present invention to provide a revetment block capable of effectively preventing a drop.

[0009]

According to a first aspect of the present invention, there is provided a seawall block in which a plurality of substantially cone-shaped projections made of concrete are arranged such that the tops thereof are on the same side, and the bottoms are joined to each other. And the entire block shape,
A space that expands from the bottom side to the top side is formed between the protrusions, and the protrusions are arranged in a matrix of a plurality of rows. In the revetment block in which the odd-numbered row projections and the even-numbered row projections are displaced in the column direction so as to correspond to the space, a large number of revetment blocks are formed in a matrix shape as a whole. And when the row direction of the projection part of the revetment block adjacent to the front and back and / or right and left is arranged so that it may cross each other, the projection part of the even number row of one adjacent revetment block may become Corresponding to the groove-like space between the rows of the projections, the projections in the even-numbered rows of one revetment block block the spaces between the rows of the projections of the other revetment blocks at adjacent positions.

Therefore, a desired seawall can be constructed by laying a large number of seawall blocks of claim 1 as installation units in a seawall construction work, for example, a law lining (low-water seawall) or a rock pier. Can be formed. At this time, since the revetment blocks are unitized, the entire revetment as a unit system can be easily and quickly constructed. As a result, the labor and time required for on-site work can be reduced, and workability can be improved.

Further, depending on the combination and arrangement of the seawall blocks as units, watersides or riverbanks of various shapes can be artificially and easily formed. For example, a linear river flow path due to concrete revetment found especially in small and medium-sized rivers has a meandering shape close to the shape of a natural river with a creek and a deep edge, and a wand is formed at a desired location. Can be easily formed. As a result, it is possible to easily form a revetment of any shape that is more effective for creation and conservation of an ecosystem.

[0012] The revetment block is laid so that the length direction of the projection is substantially perpendicular to the installation surface. For example, when applied to low-water revetments, the projections extend diagonally approximately perpendicular to the slope of the low-water revetment, and when applied to shoring, the projections extend approximately perpendicular to the riverbed surface at the shore. Extend vertically.

Further, after installation, the space formed between the protrusions of each revetment block performs various functions. For example,
When the revetment block of claim 1 is laid as a low-water revetment, usually, a cover soil is provided on the upper surface side of the revetment block for greening, and vegetation is activated on the cover soil to achieve greening. Here, in the revetment block according to the first aspect, the space between the projections expands from the bottom side to the top side of the projections, and has a sufficient volume to hold a large amount of soil (cover soil). It functions as a holding tank and prevents sliding (peeling) of soil (covering soil). As a result, the outflow of the soil cover can be prevented, and the outflow of the vegetation growing on the soil cover can also be prevented. Also, since a large amount of cover soil can be stably held on the seawall block for a long period of time, woody plants (especially shrubs) as well as herbs can be grown as vegetation.

Further, when the revetment block of claim 1 is laid as a shoring work, the projections have sufficient resistance to flowing water to reduce the flow velocity, thereby alleviating sudden riverbed scouring or the like caused by flowing water. As a result, the revetment block can effectively exert the flood control function as a shoring work. Also,
The space between the projections forms a growth space for aquatic organisms such as fish nests. As a result, it is possible to create an environment suitable for aquatic organisms and contribute to the creation and conservation of biotopes.

[0015] When the revetment block is laid as a low-water revetment and the revetment block receives flowing water at the time of rising water, the projections reduce the flow velocity and the flood control function as the low-water revetment is achieved in the same manner as described above. It can be used effectively.

In the first aspect of the present invention, a cover is provided on the low-water revetment, and a low-water revetment is provided at least on a revetment block adjacent to the low-water revetment. Covering soil may be provided continuously to the covering of the seawall. In this case, the space between the protruding portions of the seawall block of the shoring work is also filled with soil, and it is possible to plant water-based plants such as reeds. In other words, it is possible to plant waterside vegetation, which is an important element for creation and conservation of river ecosystems. In addition, it becomes possible for a person or the like to walk on the soil covered by the seawall at the water's edge, so that a hydrophilic area can be provided to local residents and the like. In addition, the low-water revetment and revetment revetment blocks and soil cover form a gentle slope from the terrestrial sphere to the hydrosphere. Here, the gentle slope enables the insects to move from the hydrosphere to the terrestrial sphere and is an essential element for the spawning and growth of the insects, so that the habitat of the insects can be secured.
In addition, even when it is applied to the shoring work, the space between the protrusions of the revetment block has a sufficient volume and functions as a soil holding tank to prevent the outflow of the covering soil.

Further, the revetment block is formed of a concrete material. The revetment block is integrally formed in a block shape in advance using a predetermined mold at a factory or the like. Here, the concrete material is used as a main material in the conventional revetment work, and can be inexpensively and stably supplied. As a result, it is easy to secure the material, and it is possible to stably supply the revetment block itself. Also,
Mass production of revetment blocks is also possible, which can reduce manufacturing costs in addition to material costs. Further, it is possible to effectively prevent deterioration in functions such as strength and durability due to corrosion.

In the revetment block according to the first aspect, the bottom surfaces of a plurality of substantially conical projections are joined to each other to form a substantially flat surface, and the projections protrude from one side of the joint. It can be. In this case, the revetment block can be stably arranged and held on the soil surface or the like at the laying point, and is particularly suitable for low-water revetment. In addition, it is of course possible to provide an additional configuration such as another protrusion on the other side of the bottom surface side of the seawall block.

In particular, in the revetment block according to the first aspect, since the projections have a substantially pyramid shape such as a cone or a pyramid, the cross-sectional shape of the space between the projections expands symmetrically with the projections toward the top of the projections. And has a sufficient porosity (porosity). as a result,
Each seawall block functions as a fish nest or the like by itself, and can provide a favorable environment for fish and the like. In addition, even if the space of each revetment block is closed due to flooding or sedimentation due to aging, as described above,
A plurality of revetment blocks are combined and arranged in a predetermined manner,
By forming a wand of a predetermined shape, the wand itself constitutes a habitable space for a long-life underwater creature such as a large fish nest. In other words, the seawall wand as a unit system composed of a large number of seawall blocks exhibits a function as a habitat for aquatic organisms such as fish nests for a long time. In addition,
Since the wand has a natural curved shape due to sedimentation over time, it is possible to create and maintain a biotope using erosion and sedimentation.

Further, in the revetment block according to the first aspect, the protrusions arranged in a matrix form have greater frictional resistance. Further, the space between the projections has a more complicated shape. Therefore, for example, when the revetment block is applied to a low-water revetment, the space between the protrusions more effectively exerts a soil holding function and the like. In addition, when the revetment block is applied to the shoring work, the protruding portions more effectively exhibit a flow velocity reducing function and the like.
Furthermore, the projections of the odd-numbered columns and the even-numbered columns are displaced in the column direction, and the projections of the even-numbered columns correspond to the spaces between the projections of the odd-numbered columns. The resistance increases.

Here, in low-water revetment and / or embankment work, a large number of revetment blocks are formed in a matrix shape and the row direction of the protrusions of the revetment blocks adjacent to the front, rear, and / or left and right. Are arranged so as to intersect each other, so that the projections in the even-numbered rows of one adjacent revetment block correspond to the groove-shaped spaces between the projection rows of the other adjacent revetment blocks. That is, the projections of the even-numbered rows of one revetment block block the space between the rows of the other revetment blocks at adjacent positions. Such even-numbered-row projections are arranged so as to cross each other between adjacent seawall blocks, and increase the resistance in both the row direction and the column direction on the entire laying surface of the seawall. As a result, by arranging the revetment blocks so that their row direction coincides with the flowing water direction or the normal direction, the soil retaining function and running water mitigation function are exhibited more effectively in both the normal direction and the flowing water direction. can do.

In the revetment block according to the second aspect, a plurality of substantially pyramid-shaped projections made of concrete are arranged so that their tops are on the same side, and the bottoms are joined together to form a block shape as a whole. While forming a space between the protrusions that expands from the bottom side toward the top side,
The protrusions are arranged in a matrix of a plurality of rows, and the odd-numbered protrusions and the even-numbered protrusions are arranged so that the protrusions of each even-numbered row correspond to the spaces between the protrusions of each odd-numbered row. In the row direction, wherein the projections of each even-numbered row block the space between the corresponding projections of the odd-numbered row, and a large number of revetment blocks are entirely made up of a matrix. When the protruding portions of the revetment blocks adjacent to the front and rear and / or left and right are arranged so as to intersect each other, the protruding portions of the even-numbered row of one revetment block are adjacent to the other revetment blocks. Corresponding to the groove-shaped space between the rows of protrusions of the revetment block, so that the projections of the even-numbered rows of one revetment block block the space between the rows of protrusions of the other revetment block at adjacent positions. did.

In the revetment block according to the third aspect, a plurality of substantially pyramid-shaped projections made of concrete are arranged so that their tops are on the same side, and the bottoms are joined together to form a block shape as a whole. While forming a space between the protrusions that expands from the bottom side toward the top side,
The protrusions are arranged in a matrix of a plurality of rows, and the odd-numbered protrusions and the even-numbered protrusions are arranged so that the protrusions of each even-numbered row correspond to the spaces between the protrusions of each odd-numbered row. Is a revetment block in which the positions are shifted in the column direction, wherein the cross-sectional shape of each of the protrusions and the cross-sectional shape of each space between the protrusions correspond to the odd-numbered rows where the even-numbered rows of protrusions correspond to the odd-numbered rows. The cross-sectional shape completely blocks the space between the projections, and a large number of revetment blocks have a matrix shape as a whole, and the row directions of the projections of the revetment blocks adjacent to the front, rear, and / or left and right intersect each other. When arranged in such a way, the projections in the even-numbered row of the adjacent revetment block
Corresponding to the groove-shaped space between the rows of adjacent revetment blocks, the even-numbered rows of one revetment block block the space between the rows of other revetment blocks at adjacent positions. I did it.

In the revetment block according to a fourth aspect, a plurality of substantially cone-shaped projections made of concrete are arranged so that the top side is the same side, and the bottom sides are joined together to form a block shape as a whole. While forming a space between the protrusions that expands from the bottom side toward the top side,
The protrusions are arranged in a matrix of a plurality of rows, and the odd-numbered protrusions and the even-numbered protrusions are arranged so that the protrusions of each even-numbered row correspond to the spaces between the protrusions of each odd-numbered row. A seawall block in which the positions are shifted in the column direction, wherein the diameter of the upper end of the projection is larger than the width of the upper end of the space between the projections, and the projections of each even-numbered row are the odd numbers. The space between the corresponding projections of the row is completely blocked, and a large number of revetment blocks are formed in a matrix shape, and the row direction of the projections of the revetment blocks adjacent to the front, rear, and / or left and right is adjusted. When arranged so as to intersect with each other, the projections in the even-numbered rows of one adjacent revetment block correspond to the groove-shaped spaces between the rows of the projections of the other adjacent revetment blocks, and the even-numbered Row projections are other revetment blocks The space between the rows of projections and adapted to cut off at adjacent positions.

According to a fifth aspect of the present invention, there is provided a revetment block in which a plurality of substantially spindle-shaped projections made of concrete are arranged substantially in parallel with each other such that the tops thereof are on the same side. The central portions between them are joined together to form a block shape as a whole, and a space is formed between the projections that expands from the central portion toward each top side, and the projections are formed into a matrix in a plurality of rows. A revetment in which the odd-numbered row projections and the even-numbered row projections are displaced in the column direction such that the even-numbered row projections correspond to the spaces between the odd-numbered row projections. When a plurality of revetment blocks are arranged such that the whole of the revetment blocks have a matrix shape and the row directions of the protrusions of the revetment blocks adjacent to the front and rear and / or left and right intersect with each other, one of the revetment blocks is adjacent. The projections of the even-numbered row of the revetment block correspond to the groove-shaped spaces between the rows of the projections of the other revetment blocks, and the projections of the even-numbered row of one revetment block correspond to the projections of the other revetment block. The space between rows was blocked at adjacent positions.

Here, the shape of the projection may be a substantially spindle shape having a predetermined length as a whole. The substantially spindle shape is a shape in which two substantially conical shapes are joined on the bottom side. In addition, the substantially pyramidal shape that forms the half of the substantially spindle-shaped protruding portion may be a cone, a pyramid, or the like, in addition to a pure cone having a sharp apex, or a truncated cone or a truncated pyramid having a sharply cut apex. good.
Further, a shape in which the cross section changes stepwise or discontinuously or irregularly, such as a stepped cone shape, a bellows cone shape, etc., is also included.

Therefore, in the revetment work, for example, in the law lining work (low water revetment etc.) or the shoring work, the desired revetment is laid by using the revetment block of claim 5 as one unit (unit). Can be formed. At this time, since the revetment blocks are unitized, the entire revetment as a unit system can be easily and quickly constructed. As a result, the labor and time required for on-site work can be reduced, and workability can be improved.

Also, depending on the combination and arrangement of the revetment blocks as units, watersides or riverbanks of various shapes can be artificially and easily formed. For example, a linear river flow path due to concrete revetment found especially in small and medium-sized rivers has a meandering shape close to the shape of a natural river with a creek and a deep edge, and a wand is formed at a desired location. Can be easily formed. As a result, it is possible to easily form a revetment of any shape that is more effective for creation and conservation of an ecosystem.

In the revetment block according to the fifth aspect, since spaces are formed on both sides in the length direction from the center of the substantially spindle-shaped projection, various spaces such as fish nests are formed on both sides of the space. Can be used for purpose. Therefore, the revetment block according to claim 5 is particularly suitable for the shoring work.

The revetment block is laid so that the length direction of the projection is substantially perpendicular to the installation surface. For example, when applied to low-water revetments, the projections extend diagonally approximately perpendicular to the slope of the low-water revetment, and when applied to shoring, the projections extend approximately perpendicular to the riverbed surface at the shore. Extend vertically.

Further, when the revetment block according to the fifth aspect is laid as a shoring work, the projections have sufficient resistance to flowing water to reduce the flow velocity, and alleviate sudden riverbed scouring or the like due to flowing water. In particular, since the upper and lower halves of the projection each having a substantially conical shape project upward and downward, the upper and lower portions of the water exhibit a flow velocity reducing function. As a result, the revetment block can effectively exert the flood control function as a shoring work. The space between the projections forms a growth space for aquatic organisms such as fish nests on the upper and lower sides of the projections. As a result, it is possible to create an environment suitable for aquatic organisms and contribute to the creation and conservation of biotopes.

In particular, in the revetment block according to the fifth aspect, since the protrusion is substantially spindle-shaped, the cross-sectional shape of each space above and below the protrusion is symmetrical to the top of the protrusion. It expands and has a sufficient porosity (porosity). (In the first embodiment, it is about 50%, which is almost the same as the case of the solidification work using cobbles.) As a result, each revetment block functions as a fish nest or the like by itself, and inhabits fish and the like. A good environment can be provided. Further, even when the space of each revetment block is closed due to flooding or sedimentation due to aging, as described above, a plurality of revetment blocks are arranged in a predetermined manner to form a wand of a predetermined shape, thereby forming a wand. It forms a habitat for aquatic life such as a large fish nest with a long life. In other words, the seawall wand as a unit system composed of a large number of seawall blocks exhibits a function as a habitat for aquatic organisms such as fish nests for a long time. In addition, since this wand has a natural curved shape due to sedimentation due to aging, it is possible to create and maintain a biotope using erosion accumulation.

According to a fifth aspect of the present invention, a cover is provided on the low-water revetment, and a low-water revetment is provided at least on the revetment block on the shore (on the side of the butt) adjacent to the low-water revetment. Covering soil may be provided continuously to the covering of the seawall. Here, in the revetment block according to the third aspect, the space above the protrusion particularly expands from the center side of the protrusion toward the top end side, has a sufficient volume, and allows a large amount of soil (cover soil). It functions as a soil holding tank to hold, and prevents sliding (separation) of soil (covering soil). As a result, the outflow of the soil cover can be prevented, and the outflow of the vegetation growing on the soil cover can also be prevented. In addition, a large amount of cover soil can be stably held on the revetment block for a long time. in this case,
The space between the protruding portions of the seawall block of the shoring work is also filled with soil, and it is possible to plant aqueous plants such as reeds. That is,
Border vegetation can be planted, which is an important element for the creation and conservation of river ecosystems. In addition, it becomes possible for a person or the like to walk on the soil covered by the seawall at the water's edge, so that a hydrophilic area can be provided to local residents and the like. In addition, the low-water revetment and revetment revetment blocks and soil cover form a gentle slope from the terrestrial sphere to the hydrosphere. Here, the gentle slope enables the insects to move from the hydrosphere to the terrestrial sphere and is an essential element for the spawning and growth of the insects, so that the habitat of the insects can be secured.

The revetment block of claim 5 can be laid as a low water revetment. In this case, usually
For revegetation, cover soil will be provided on the upper surface side of the revetment block, and vegetation will be activated on the cover soil for greening. And even when it is applied to a low water revetment, the space between the protrusions of the revetment block has a sufficient volume and functions as a soil holding tank to prevent the outflow of the covering soil. In addition, woody plants (especially shrubs) as well as herbs can be grown as vegetation.

Furthermore, when the revetment block is laid as a low-water revetment and the revetment block receives flowing water when the water is increased, the protrusions reduce the flow velocity and the flood control function as the low-water revetment is achieved in the same manner as described above. It can be used effectively.

The revetment block is made of a concrete material. The revetment block is integrally formed in a block shape in advance using a predetermined mold at a factory or the like. Here, the concrete material is used as a main material in the conventional revetment work, and can be inexpensively and stably supplied. Therefore, it is easy to secure the material, and
The stable supply of the revetment block itself becomes possible. In addition, mass production of revetment blocks is possible, in addition to material costs,
Manufacturing costs can also be reduced. Further, it is possible to effectively prevent deterioration in functions such as strength and durability due to corrosion.

Further, the projections arranged in a matrix form have a greater frictional resistance. Further, the space between the projections has a more complicated shape. Therefore, for example, when the revetment block is applied to a low-water revetment, the space between the protrusions more effectively exerts a soil holding function and the like. In addition, when the revetment block is applied to the shoring work, the protruding portions more effectively exhibit a flow velocity reducing function and the like. Furthermore, the projections of the odd-numbered columns and the even-numbered columns are displaced in the column direction, and the projections of the even-numbered columns correspond to the spaces between the projections of the odd-numbered columns. The resistance increases.

Here, in low-water revetment and / or embankment work, a large number of revetment blocks are formed in a matrix shape and the row direction of the protrusions of the revetment blocks adjacent to the front, rear, and / or left and right. Are arranged so as to intersect each other, so that the projections in the even-numbered rows of one adjacent revetment block correspond to the groove-shaped spaces between the projection rows of the other adjacent revetment blocks. That is, the projections of the even-numbered rows of one revetment block block the space between the rows of the other revetment blocks at adjacent positions. Such even-numbered-row projections are arranged so as to cross each other between adjacent seawall blocks, and increase the resistance in both the row direction and the column direction on the entire laying surface of the seawall. As a result, by arranging the revetment blocks so that their row direction coincides with the flowing water direction or the normal direction, the soil retaining function and running water mitigation function are exhibited more effectively in both the normal direction and the flowing water direction. can do.

According to a sixth aspect of the present invention, there is provided a revetment block in which a plurality of substantially spindle-shaped projections made of concrete are arranged substantially in parallel with each other such that the tops thereof are on the same side. The central portions between them are joined together to form a block shape as a whole, and a space is formed between the projections that expands from the central portion toward each top side, and the projections are formed into a matrix in a plurality of rows. A revetment in which the odd-numbered row projections and the even-numbered row projections are displaced in the column direction such that the even-numbered row projections correspond to the spaces between the odd-numbered row projections. A block, wherein each even-numbered row of projections blocks a space between the corresponding odd-numbered row of projections, and a number of revetment blocks are formed so as to be entirely matrix-shaped, and
Or when the row direction of the projections of the adjacent revetment blocks intersect each other, the projections of the even-numbered rows of one adjacent revetment block may be located between the rows of the projections of the other adjacent revetment blocks. Corresponding to the groove-like space, the projections in the even-numbered rows of one revetment block block the spaces between the rows of the projections of the other revetment blocks at adjacent positions.

According to a seventh aspect of the present invention, there is provided a revetment block in which a plurality of substantially spindle-shaped projections made of concrete are arranged substantially in parallel with each other so that their tops are on the same side, and both tops of the respective projections are arranged. The central portions between them are joined together to form a block shape as a whole, and a space is formed between the projections that expands from the central portion toward each top side, and the projections are formed into a matrix in a plurality of rows. A revetment in which the odd-numbered row projections and the even-numbered row projections are displaced in the column direction such that the even-numbered row projections correspond to the spaces between the odd-numbered row projections. A block, wherein the cross-sectional shape of each of the protrusions and the cross-sectional shape of each of the spaces between the protrusions are cross-sections in which the even-numbered-row protrusions completely block the space between the corresponding protrusions in the odd-numbered row. Shape and a number of revetment blocks Are arranged so that the whole becomes matrix-like and the row directions of the protrusions of the adjacent seawall blocks cross each other in the front-rear and / or left-right direction. But,
Corresponding to the groove-shaped space between the rows of adjacent revetment blocks, the even-numbered rows of one revetment block block the space between the rows of other revetment blocks at adjacent positions. I did it.

According to an eighth aspect of the present invention, there is provided a seawall block in which a plurality of substantially spindle-shaped projections made of concrete are arranged substantially in parallel with each other so that their tops are on the same side. The central portions between them are joined together to form a block shape as a whole, and a space is formed between the projections that expands from the central portion toward each top side, and the projections are formed into a matrix in a plurality of rows. A revetment in which the odd-numbered row projections and the even-numbered row projections are displaced in the column direction such that the even-numbered row projections correspond to the spaces between the odd-numbered row projections. Block, wherein the diameter of the top end of the projection is larger than the width of the top end of the space between the projections, so that the projections of each even-numbered row completely fill the space between the corresponding projections of the odd-numbered row. So as to cut off many seawalls When the locks are arranged in a matrix shape as a whole and the row direction of the protrusions of the revetment blocks adjacent to the front and rear and / or left and right intersect each other, the protrusions of the even-numbered row of the adjacent revetment blocks are arranged. The part corresponds to the groove-like space between the rows of the protrusions of the other revetment blocks, and the projections of the even-numbered rows of one revetment block adjoin the space between the rows of the protrusions of the other revetment block. I cut it off at the position.

According to a ninth aspect of the present invention, there is provided a seawall block according to the first aspect.
In any one of the constitutions from 1 to 8, the projections are arranged in a matrix with a plurality of rows, the number of rows of the projections is an odd number of 3 or more, and the number of projections in each odd-numbered row is the number of rows. With the same number as, the number of the projections of each even-numbered row is set to a number less than the number of rows by one, so that the projections of each even-numbered row correspond to the spaces between the projections of each odd-numbered row,
The odd-numbered rows of projections and the even-numbered rows of projections were arranged at different positions in the column direction.

Therefore, the protrusions arranged in a matrix form have greater frictional resistance. Further, the space between the projections has a more complicated shape. Therefore, for example, when the revetment block is applied to a low-water revetment, the space between the protrusions more effectively exerts a soil holding function and the like. In addition, when the revetment block is applied to the shoring work, the protruding portions more effectively exhibit a flow velocity reducing function and the like. Furthermore, the projections of the odd-numbered columns and the even-numbered columns are displaced in the column direction, and the projections of the even-numbered columns correspond to the spaces between the projections of the odd-numbered columns. The resistance increases.

Further, since the number of the odd-numbered row projections is the same as the total number of rows, the overall shape of the revetment block is substantially a square block. Further, since the number of the projections in the even-numbered row is set to one less than the number of the rows (the number of the projections in the odd-numbered row), the number of the groove-shaped spaces between the rows is the same as the number of the projections in the even-numbered row. . Therefore, the projections in each even-numbered row all correspond to the spaces between the odd-numbered row projections on both sides in a one-to-one relationship, and are not located outside the odd-numbered row projections. As a result, many revetment blocks can be arranged neatly and closely, and a desired revetment shape can be easily obtained.

Here, in low-water revetment and / or embankment work, a large number of revetment blocks are formed in a matrix shape, and the row direction of the protrusions of the revetment blocks adjacent to the front and rear and / or left and right is arranged. Are arranged so as to intersect each other, so that the projections in the even-numbered rows of one adjacent revetment block correspond to the groove-shaped spaces between the projection rows of the other adjacent revetment blocks. In particular, since the number of groove-shaped spaces between rows and the number of projections in the even-numbered row are the same, the projections in the even-numbered row of one adjacent revetment block may be located between the adjacent rows of the other revetment blocks. All in a one-to-one relationship. That is, the projections in the even-numbered rows of one revetment block block all spaces between rows of the other revetment blocks at adjacent positions. And such an even row of projections,
It is arranged crossing each other between adjacent revetment blocks, and increases the resistance in both the row direction and the column direction on the entire laying surface of the revetment block. As a result, revetment blocks
By arranging such that the row direction coincides with the flowing water direction or the normal water direction, it is possible to more effectively exhibit the soil holding function and the flowing water mitigation function in both the normal direction and the flowing water direction.

According to a tenth aspect of the present invention, in the configuration of the ninth aspect, the protrusions are arranged in a matrix having three rows, three in the left row, two in the center row, and three in the right row. In addition, the center row projections and the left row and right row projections are arranged so that each projection in the center row corresponds to each space formed between the left row and right row projections. The positions were shifted in the column direction.

Therefore, a small number of protrusions can be used.
It has the same effect as the revetment block and can exhibit the same effect.

According to an eleventh aspect of the present invention, there is provided the seawall block according to the tenth aspect, wherein the three projections in the left row, the three projections in the right row, and the two projections in the central row. Corresponding to the displacement, recesses having a substantially trapezoidal plane were formed on both sides of the two projections in the central row.

According to a twelfth aspect of the present invention, in the revetment block according to any one of the first to eleventh aspects, a through hole is formed between the projections so as to penetrate in the length direction of the projection.

Therefore, the through-hole penetrates the joint between the projecting portions of the revetment block, and it is possible to circulate on both sides thereof. As a result, for example, when applied to a low-water revetment, the through-hole can be filled with soil, and the soil holding function increases. In addition, when applied to the consolidation work, flowing water flows through the through holes. As a result, it is possible to expand the habitable space for underwater organisms such as fish.

Embodiments of the present invention will be described below. Throughout the embodiments, the same members or elements will be denoted by the same reference characters and will not be described.

FIG. 1 is a front view showing a revetment block according to Embodiment 1 of the present invention. FIG. 2 is a plan view showing the revetment block according to Embodiment 1 of the present invention. FIG. 3 is FIG.
FIG. 4 is a sectional view taken along line AA of FIG.

As shown in FIGS. 1 to 3, the revetment block 10 according to the first embodiment includes a plurality of protrusions 11 and a joint 12. Each projection 11 is formed in a substantially spindle shape from porous concrete. In the first embodiment, a total of eight protrusions 11 are arranged substantially parallel to each other such that their top sides are on the same side (upper side and lower side), and each of the protrusions 11 is joined by a joint 12 made of porous concrete. The central portion between the tops of the protrusions 11 is joined to each other. Thus, the entire shape of the revetment block 10 is a substantially square flat plate block made of porous concrete. Further, a through hole 13 is formed between the adjacent protrusions 11 so as to penetrate in the length direction of the protrusion 11 (the thickness direction of the joint 12). Also, between the projections 11,
A space 14 is formed which expands from the center toward each top.

More specifically, each projection 11 has a spindle shape in which two regular octagonal truncated pyramids are joined to each other on the bottom surface and the center is expanded. In addition, the eight protrusions 11
The left column is three, the central column is two, and the right column is three. Three rows of projections 11
Are arranged parallel to each other. Further, the projections 11 in the left and right rows are arranged at the same position in the row direction. Also, the central row of projections 11 and the left and right rows of projections 11 correspond exactly to the center of each space 14 formed between the left row of projections 11 and the right row of projections 11. The row projections 11 are arranged at different positions in the row direction.

The joining portion 12 has a flat plate shape having a thickness corresponding to the central portion of the projecting portion 11 and is joined with the projecting portions 11 separated by a predetermined distance. Therefore, the side surface of the protrusion 11 to which the joint 12 is joined is covered by the thickness of the joint 12, and the height of the space 14 is
The protrusion height of the protrusion 11 from the upper surface and the lower surface of the joint portion 12 is obtained. In addition, the through hole 13 has a spindle shape in which two regular octagonal truncated pyramids are joined to each other on a flat top surface thereof, corresponding to the shape between the adjacent protrusions 11, and the center is narrowed. Further, since the protrusion 11 has a spindle shape, the space 14 is formed on the upper surface side and the lower surface side of the joint portion 12, respectively. The center of the front end (lower end in FIG. 1) and the center of the rear end (upper end in FIG. 1) of the revetment block 10 correspond to the displacement of the left and right rows of projections 11 and the center row of projections 11, respectively. Thus, a recess 15 having a substantially trapezoidal planar shape is formed.

The revetment block according to the first embodiment configured as described above is premised on being mainly applied to the shoring work.

Next, the operation and effect of the seawall block according to the first embodiment configured as described above will be described.

In the first embodiment, the revetment block 10 is regarded as one unit (unit), and in the revetment work, in particular, in the revetment work, a desired revetment (revetment work) can be formed by laying a large number at the installation location. it can. At this time, since the revetment block 10 is unitized, the entire revetment as a unit system can be easily and quickly constructed. As a result, the labor and time required for on-site work can be reduced, and workability can be improved.

The revetment block 10 as a unit
By various combinations and arrangements, it is possible to artificially and easily form shores or river banks of various shapes. For example, a straight channel formed by concrete revetment, especially found in small and medium-sized rivers, has a meandering shape close to the shape of a natural river with a valley and an edge, and forms a wand at a desired location.
A variety of riverbank shapes can be easily formed.
As a result, it is possible to easily form a revetment of any shape that is more effective for creation and conservation of an ecosystem.

The revetment block 10 of the first embodiment
Since the space 14 is formed on both sides in the longitudinal direction from the center of the spindle-shaped projection 11 as a boundary, the space 14 on both sides can be used for various purposes such as a fish nest. Therefore, the revetment block 10 according to the first embodiment is particularly suitable for the foundation work.

The revetment block 10 is laid so that the length direction of the projection 11 is substantially perpendicular to the installation surface. For example,
In the case where the present invention is applied to the shoring work, the protruding portion 11 is formed so as to extend substantially perpendicularly to the riverbed surface at the shore and vertically.

Further, when the revetment block 10 according to the first embodiment is laid as a solidification work, the protruding portions 11 have sufficient resistance to flowing water to reduce the flow velocity, and alleviate sudden riverbed scouring or the like caused by flowing water. I do. In particular, since the upper and lower halves of the projection 11 each having a truncated cone shape protrude upward and downward, the projection 11 exerts a flow velocity reducing function at the upper and lower portions in water, respectively. As a result, the revetment block 10 can effectively exert a flood control function as a shoring work. The space 14 between the projections 11 forms a growth space for aquatic organisms such as fish nests on the upper and lower sides of the projections 11, respectively.
As a result, it is possible to create an environment suitable for aquatic organisms and contribute to the creation and conservation of biotopes.

In particular, in the revetment block 10 according to the first embodiment, since the projection 11 has a spindle shape, the projection 11
The cross-sectional shape of each of the upper and lower spaces 14 is
Symmetrically, it expands to the top side of the protrusion 11 and has a sufficient porosity (porosity). In the first embodiment, the porosity is about 50%, which is almost the same as the case of the consolidation using cobblestone. As a result, each revetment block 10 functions as a fish nest or the like by itself, and can provide a favorable environment for fish and the like. Further, even when the space 14 of each revetment block 10 is closed due to flooding or sedimentation due to aging, as described above, a plurality of revetment blocks 1 are required.
The wands themselves constitute a long-life habitat for underwater organisms such as large fish nests by arranging the wands in a predetermined manner to form a wand of a predetermined shape. In other words, a seawall wand as a unit system by a large number of seawall blocks 10 exhibits a function as a habitat for underwater organisms such as fish nests for a long time. This wand,
Because it becomes a natural curved shape due to sediment accumulation due to aging,
Biotopes can also be created and preserved using erosion and sedimentation.

Further, in the first embodiment, soil is provided on the low-water revetment, and at least one of the revetment blocks 10 installed as a shoring work, on the shore (on the side of the butt) adjacent to the low-water revetment. In addition, soil covering may be provided continuously with the soil covering of the low water revetment. Here, in the revetment block 10 of the first embodiment, the space 14 above the projection 11 is particularly
It expands from the center side of the protrusion 11 toward the top end side,
It has a sufficient volume and functions as a soil holding tank that holds a large amount of soil (cover soil), and prevents the soil (cover soil) from sliding and peeling. As a result, the outflow of the soil cover can be prevented, and the outflow of the vegetation growing on the soil cover can also be prevented. Moreover, a large amount of soil can be stably held on the revetment block 10 for a long time.

In this case, the space 14 between the projections 11 of the seawall block 10 of the shoring work is also filled with soil, and it is possible to plant water-based plants such as reeds. In other words, it is possible to plant waterside vegetation, which is an important element for creation and conservation of river ecosystems. In addition, it becomes possible for humans and the like to walk on the soil covered by the seawall block 10 at the water's edge, thereby providing a hydrophilic area to local residents and the like. Furthermore, the revetment block 10 and the soil covering of the low-water revetment and the embankment form a gentle slope from the land area to the hydrosphere. Here, the gentle slope enables the insects to move from the hydrosphere to the terrestrial sphere and is an essential element for the spawning and growth of the insects, so that the habitat of the insects can be secured.

The revetment block 10 of the first embodiment can be laid as a low water revetment. in this case,
Usually, a cover is provided on the upper surface side of the revetment block 10 for greening, and vegetation is activated on the cover to achieve greening. And even when it is applied to a low water revetment, the space between the projections 11 of the revetment block 10 has a sufficient volume and functions as a soil holding tank to prevent the outflow of the covering soil. In addition, woody plants (especially shrubs) as well as herbs can be grown as vegetation. Furthermore, when the revetment block 10 is laid as a low-water revetment, even when the revetment block 10 receives flowing water at the time of increasing the water level, the protrusions 11 reduce the flow velocity as described above, and the flood control function as the low-water revetment is achieved. It can be used effectively.

The revetment block 10 is formed of porous concrete, and is integrally formed in a block shape in advance in a factory or the like using a predetermined mold. Here, cement, the material of porous concrete,
It is used as a main material for conventional revetment work, and is cheap and can be supplied stably. Also, coarse aggregate, which is an aggregate of porous concrete, can be inexpensively and stably supplied. Therefore, the material can be easily secured, and the stable supply of the revetment block 10 itself can be achieved. In addition, mass production of the revetment block 10 becomes possible, and the production cost can be reduced in addition to the material cost. Further, it is possible to effectively prevent deterioration in functions such as strength and durability due to corrosion.

Further, in the first embodiment, the projections 11 arranged in a matrix form have higher frictional resistance. Further, the space 14 between the protrusions 11 has a more complicated shape.
Therefore, for example, when the revetment block 10 is applied to the shoring work, the protrusions 11 more effectively exhibit the soil holding function, the flow velocity reducing function, and the like. Furthermore, since the projections 11 of the odd-numbered rows and the even-numbered rows are displaced in the row direction and the projections 11 of the even-numbered rows correspond to the spaces between the projections 11 of the odd-numbered rows, in each revetment block 10, In particular, the resistance in the row direction increases.

Further, since the number (three) of the odd-numbered rows of projections 11 is equal to the total number of rows (three rows), the revetment block 1
0 has a substantially rectangular block shape. In addition, the number of the projections 11 in the even-numbered row is set to one number (two) smaller than the number of rows (the number of the projections 11 in the odd-numbered row). The number of parts 11 is the same. Therefore, the projections 11 in each even-numbered row all correspond to the spaces between the adjacent odd-numbered rows of projections 11 in a one-to-one relationship, and are not positioned outside the odd-numbered rows of projections 11. As a result, many revetment blocks 10 can be arranged neatly and closely, and a desired revetment shape can be easily obtained.

In addition, the through-hole 13 penetrates the joint 12 between the protrusions 11 of the revetment block 10, and the circulation on both sides is enabled. As a result, for example, the through hole 13 can be filled with soil, and the soil holding function increases.
In addition, when applied to the consolidation work, flowing water flows through the through holes 13. As a result, it is possible to expand the habitable space for underwater organisms such as fish. Further, since the recess 15 forms a relatively large space between the adjacent seawall block 10, this space can be used as a habitat for fish and the like.

The porous concrete forming the revetment block 10 is porous and has a high porosity. Therefore, the revetment block 10 of the first embodiment
Has a rough surface, and algae serving as baits such as fishes are likely to adhere thereto. As a result, a better habitat for fish and the like can be provided. In addition, a water purification effect can be expected through the porous void. In particular, by mixing the water purification material into the porous concrete and exposing it to the surface of the void portion, better water purification can be expected. In order to make the revetment block 10 porous, it is preferable to join the coarse aggregate with a cement paste of about 30% water cement to form a predetermined shape. In this case, abrasion resistance and durability against running water are remarkably improved.

FIG. 4 is a front view showing a revetment block according to Embodiment 2 of the present invention. FIG. 5 is a plan view showing a revetment block according to Embodiment 2 of the present invention. FIG. 6 is a bottom view showing the revetment block according to Embodiment 2 of the present invention.

As shown in FIG. 4 and FIG. 6, the revetment block 20 according to the second embodiment divides the revetment block 10 according to the first embodiment into two parts at the center in the height direction (the length direction of the protrusion 11). It has an overall shape. Specifically, Embodiment 2
The revetment block 20 according to
The joint 2 made of porous concrete is arranged in a state of being substantially parallel to each other so that its top side is the same side (upper side).
2, the bottom side portions between the tops of the projections 21 are joined to each other. Thus, the entire shape of the revetment block 20 is a substantially square flat plate block made of porous concrete. Furthermore, a through hole 23 is formed between the adjacent protrusions 21 so as to penetrate in the length direction of the protrusion 21 (the thickness direction of the joint 22). Also, the protrusion 2
A space 24 that extends upward from the bottom side toward the top side is formed between the two. Each projection 21 has a regular octagonal truncated pyramid shape. The eight projections 21 are arranged in the same manner as the projections 11 of the first embodiment.

The joining portion 22 is formed in a flat plate shape having a thickness corresponding to the bottom side portion of the projection 21 and is joined with the projections 21 separated by a predetermined distance. Therefore, the joint 22
The side surface of the projection 21 to which the projections 21 are joined is covered by the thickness of the junction 22, and the height of the space 24 is the projection height of the projection 21 from the upper surface of the junction 22. Further, the through hole 23 is formed in the adjacent protrusion 2.
It has a truncated regular octagonal pyramid shape whose diameter is reduced downward corresponding to the shape between the two. Further, since the protrusion 21 has a weight shape, the space 24 is formed only on the upper surface side of the joint 22. At the center of both the front and rear ends of the seawall block 20, recesses 25 each having a substantially trapezoidal plane are formed similarly to the recesses 15 of the first embodiment.

The revetment block according to the second embodiment configured as described above is mainly intended for application to low-water revetment.

Next, the operation and effect of the seawall block according to the second embodiment configured as described above will be described.

In the second embodiment, similar to the first embodiment, a large number of seawall blocks 20 are laid at installation locations in seawall construction work, especially law lining (low-water seawalls, etc.) as one unit (unit). Thus, a desired revetment can be formed, and the same operation and effect as in the first embodiment can be obtained.

The revetment block 20 of the second embodiment
Is a joint 22
And the entire bottom surface is made substantially flat, and the protrusion 21 projects from the upper side of the joint 22. Therefore, the revetment block 20 can be stably disposed and held on the soil surface or the like at the laying point, and is particularly suitable for low-water revetment. In addition, it is of course possible to provide an additional configuration such as another projection, a projection for preventing displacement, and the like on the other side of the bottom surface side of the revetment block 20.

The revetment block 20 is laid so that the length direction of the projection 21 is substantially perpendicular to the installation surface. For example,
When applied to a low-water revetment, the protrusion 21 extends obliquely substantially orthogonally to the slope of the low-water revetment.

Further, after the installation, the spaces 24 formed between the projections 21 of each revetment block 20 perform various functions. For example, when the revetment block 20 of the second embodiment is laid as a low-water revetment, usually, a cover soil is provided on the upper surface side of the revetment block 20 for greening, and vegetation is activated on the cover soil for greening. Here, in the revetment block 20 of the second embodiment, the space 24 between the projections 21
It has a sufficient volume and functions as a soil holding tank that holds a large amount of soil (cover soil) from the bottom side to the top side, and prevents the soil (cover soil) from sliding and peeling. As a result, the outflow of the soil cover can be prevented, and the outflow of the vegetation growing on the soil cover can also be prevented. In addition, revetment block 20
Since a large amount of soil can be stably retained on the soil for a long period of time, woody plants (especially shrubs) as well as herbs can be grown as vegetation.

In addition, the revetment block 20 of the second embodiment can be laid as a foundation work. Also in this case, the protrusion 21 has a sufficient resistance to the flowing water to reduce the flow velocity, thereby alleviating sudden riverbed scouring or the like caused by the flowing water. As a result, the revetment block 20 can effectively exert a flood control function as a shoring work. Also, the protrusion 2
The space 24 between the two forms a growth space for underwater creatures such as fish nests. As a result, it is possible to create an environment suitable for aquatic organisms and contribute to the creation and conservation of biotopes.

In particular, in the revetment block 20 according to the second embodiment, since the protrusion 21 has a substantially pyramid shape of a truncated octagonal pyramid,
The cross-sectional shape of the space between the projections 21 expands symmetrically with the projections 21 toward the tops of the projections 21 so that a sufficient porosity (porosity) is obtained.
Having. As a result, each revetment block 20 has the same operation and effect as in the first embodiment. Moreover, since the revetment block 20 is formed of porous concrete as in the first embodiment, the same functions and effects as those of the first embodiment can be obtained.

FIG. 7 is a plan view showing a revetment according to Embodiment 3 of the present invention. FIG. 8 is a sectional view showing a revetment according to Embodiment 3 of the present invention. FIG. 9 shows Embodiment 3 of the present invention.

Revetment blocks 20 are arranged in two rows (two rows) before and after so as to form a pure matrix. In the low-water revetment, the revetment blocks 20 are arranged so that the row directions of the protrusions 21 of the revetment blocks 20 adjacent to each other in the front-rear (normal direction) and right and left (flowing water directions) cross each other. Specifically, the revetment blocks 20 continuously arranged left and right in the front stage (the upper stage in FIG. 7) are arranged in order from the left or right, and the row direction (vertical direction in FIG. 7 (vertical direction in FIG. 7) and left and right directions (horizontal direction in FIG. 7).

On the other hand, in the shoring work, the revetment block 10 of the first embodiment is connected to the rear end (lower end in FIG. 7) of the revetment block 20 of the low water revetment so as to form a matrix. They are arranged in columns (4 rows). Also in the shoring work, the seawall blocks 10 are arranged such that the row directions of the protrusions 11 of the seawall blocks 10 adjacent to each other in the front-rear and left-right directions cross each other in the same manner as in the case of the low-water seawall.
Further, the seawall blocks 10 at the forefront of the shoring work are arranged so that the row direction of the protrusions 11 also intersects with the row direction of the protrusions 21 of the seawall block 20 at the latter stage of the adjacent low water revetment. ing. As a result, all adjacent seawalls 1
The row directions of the 0, 20 projections 11 intersect each other.

Further, in the third embodiment, a part of the seawall block 10 arranged at the shore portion (lower end portion in FIG. 7) of the seawall blocks 10 of the masonry work arranged in a matrix is omitted. A wand 40 is formed at that portion. That is, each of the six seawall blocks 10 adjacent to each other is omitted, and a wand 40 having a substantially horizontally long rectangular shape in a plane is formed.

In the third embodiment, a revetment block 30 developed for high water revetment is used as high water revetment. The revetment block 30 has a substantially rectangular flat plate shape,
It is a two-layer structure of a normal concrete layer and a porous concrete layer having water blocking properties. Further, the porous concrete layer is provided with a pot portion 31 having a long groove concave shape.
And, as a high water revetment, a number of revetment blocks 30 are arranged in a plurality of stages so as to form a matrix. In FIG. 7 and FIG. 8, the seawall block 30 of the high seawall and the seawall block 20 of the lowwater seawall are arranged adjacent to each other. Exists. On the embankment without a floodplain, both revetment blocks 20, 30 are arranged adjacent to each other as shown in the figure.

The spaces 14, 24 and the pot portions 31 of the revetment blocks 10, 20, 30 and the pot portions 31 and the upper surfaces thereof are filled with soil (covering soil) 55 made of on-site generated soil or the like. The root system is maintained and grown. The soil 55 is continuously provided on the seawall block 30 of the high seawall and the seawall block 20 of the lowwater seawall. As shown in FIG. 9, the soil 55 is provided with a low water revetment at least on the revetment block 10 on the shore (on the side of the bottom of the shore) adjacent to the low water revetment, of the revetment blocks 10 installed as a rock consolidation work. It is provided continuously on the soil 55.

Here, the revetment block 20 of the low water revetment is
The flat bottom surface composed of the lower surface of the joint portion 22 is placed and fixed on the laying surface (concrete surface) 61. In addition, the seawall block 10 of the shoring work is fixed by placing the flat surface of the lower apex of the protrusion 11 on the laying surface 61 or the riverbed surface G. In the revetment block 10, the flat surface at the top of the lower half of the protrusion 11 is located near the water surface W. In addition, the revetment block 30 of the high water revetment is fixed by placing the lower surface, which is usually the concrete side, on the laying surface 61.

Next, the function and effect of the seawall according to the third embodiment configured as described above will be described.

In the third embodiment, in low-water revetment and embankment work, even-numbered rows of projections 11 and 21 of one adjacent revetment block 10 and 20 are replaced with another adjacent revetment block 1.
It corresponds to the groove-shaped spaces 14, 24 between the rows of the 0 projections 11, 21. In particular, since the number of the groove-shaped spaces 14 and 24 between the rows is the same as the number of the projections 11 and 21 in the even-numbered rows, the projections 11 in the even-numbered rows of the adjacent revetment blocks 10 and 20 are used.
21 correspond to the groove-shaped spaces 14 and 24 between the rows of the protrusions 11 and 21 of the other revetment blocks 10 and 20 in a one-to-one relationship. That is, one revetment block 10, 20
Of the even-numbered rows of the other revetment blocks 10
The spaces 14, 24 between the 20 rows are all blocked off at adjacent positions. Then, such an even-row projection 1
The seawall blocks 10 and 20 are arranged crossing each other between adjacent seawall blocks 10 and 20, and increase the resistance in both the row direction and the column direction on the entire laying surface of the seawall blocks 10 and 20. As a result, by arranging the revetment blocks 10 and 20 such that the row direction thereof coincides with the flowing water direction or the normal direction, the soil retaining function and the flowing water mitigation function are more effectively performed in both the normal direction and the flowing water direction. Etc. can be exhibited.

Further, each and a whole of a large number of seawall blocks 10 and 20 arranged in a matrix form exhibit the functions and effects as described in the first and second embodiments. At the same time, since the revetment blocks 10, 20 are arranged in a matrix as a whole, they can be arranged more densely,
The above actions and effects can be more effectively exhibited.

Further, as described above, by appropriately arranging and omitting the revetment block 10, the wand 40 having a desired shape can be easily formed at a desired position on the shore or on the river bank. As a result, a fish nest or the like is formed by the wand 40, and a better habitat for fish and the like can be provided.

FIG. 10 is a plan view showing a revetment according to Embodiment 4 of the present invention. FIG. 11 is a sectional view showing a revetment according to Embodiment 4 of the present invention.

As shown in FIGS. 10 and 11, the revetment of the fourth embodiment is similar to the third embodiment, except that the revetment blocks 10 and 20 of the first and second embodiments are used as a low-water revetment and an embankment, respectively. I'm using Also, a number of revetment blocks 10, 20 are arranged in a matrix. On the other hand, the revetment of the fourth embodiment differs from the third embodiment in the shape of the wand 80. That is, a part of the revetment block 10 arranged at the shore portion (lower end portion in FIG. 10) is omitted in total, and the wand 80 is formed in that portion. This wand 80

Grooves between rows of parts Corresponding to between, revetment block, wherein a protruding portion of the even columns of one revetment block is to be blocked in the adjacent position the space between the rows of projections of other revetment blocks. 8. A plurality of substantially spindle-shaped projections made of concrete are arranged substantially in parallel with each other so that their tops are on the same side, and the central portions between the tops of the projections are joined to each other. To make the whole block shape,
Forming a space extending from the central portion toward each of the tops between the protrusions, arranging the protrusions in a matrix shape composed of a plurality of rows, and each even-numbered row of protrusions being an odd-numbered row of protrusions. A revetment block in which the odd-numbered row of projections and the even-numbered row of projections are displaced in the column direction so as to correspond to a space between the projections, wherein a diameter of a top end of the projection is set between the projections. Larger than the width of the top end of the space, so that the projections of each even-numbered row completely block the space between the corresponding projections of the odd-numbered row. And when the row direction of the protrusions of the revetment blocks adjacent to the front and rear and / or left and right are arranged so as to intersect each other, the protrusions of the even-numbered rows of one revetment block adjacent to the revetment block are adjacent to the other revetment blocks. Between rows of protrusions on the block Corresponding to Jo space, revetment block, wherein a protruding portion of the even columns of one revetment block is to be blocked in the adjacent position the space between the rows of projections of other revetment blocks. 9. The projections are arranged in a matrix with a plurality of rows, the number of rows of the projections is an odd number of 3 or more, and the number of projections in each odd-numbered row is the same as the number of rows. At the same time, the number of protrusions in each even-numbered row is
