[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete revetment or a revetment block and a revetment or a revetment using the block, and a plurality of revetments for slopes such as rivers and lakes and revetments for floors. The handling and the workability of the concrete revetment and revetment block where the convex type pseudo stone or pseudo rock material of the
The construction of a stable connecting block can be performed easily and accurately, so that a revetment work and a revetment work can be easily and stably formed.

[0002]

2. Description of the Related Art Instead of using natural stones for the purpose of protecting slopes of rivers and lakes and solidifying floors, there have been proposals for using artificial rock blocks instead. In other words, a simple revetment using a concrete block cannot be considered to be landscape-friendly, and the unlimited sampling of natural stones such as rocks and cobblestones will destroy the natural environment. Is adopted.

[0003] In using such a pseudo-rock block, if the same pseudo-rock is simply used, the workability is inferior and the finished state is inferior in taste even if the artificial technique of the angle is used. -344208 and JP-A-5-5-2
39813 proposes a method of manufacturing a plurality of pseudo rock materials connected by a reinforcing bar or a mesh material.

[0004]

As described above, Japanese Unexamined Patent Publication Nos. Hei 4-344208 and Hei 5-23981 have been proposed to solve the disadvantages of simply using the pseudo rock block.
No. 3 has the advantage of being able to integrally handle and construct around 10 pseudo-rock materials per square rice, but each of the pseudo-rock materials having a considerable weight is connected to each other by a simple wire or net. For this reason, there is a disadvantage that the connecting wire rod droops largely due to the weight of each pseudo rock material in the handling operation, and it is not easy to handle the cargo or to perform the setting operation at the construction site. In addition, early revegetation cannot be expected if only the soil is placed between the stones, and the habitat of living things is lost.

[0005] Further, the connected pseudo-rock materials are liable to be broken by colliding with each other during the above-described handling operation, and even when the pseudo-rock materials are formed on the slope, the external force that slides downward due to the weight of the pseudo-rock materials is reduced. Or the connecting material is likely to be displaced by flowing water at the time of flooding, the connecting material such as a wire bends and the set position fluctuates, and in some cases, the connecting material is complicated and largely bent and is likely to be jumbled. However, it has drawbacks such as difficulty in securing a stable construction state.

A typical example of the present invention is as shown in FIGS. Alternatively, in the concrete revetment or revetment block 10 composed of an aggregate of the pseudo rock materials 1, 1, 1..., The pseudo rock materials 1 are connected to each other by the connecting linear material 2 as described in JP-A-4-344208. As in the above, the connecting linear members 2 are obtained as overlapping ones at substantially constant intervals in the thickness direction of the block 10 as shown in FIG.

As described above, as a method of arranging the connecting linear members 2, 2 at substantially constant intervals, as shown in FIG. 3, a composite connecting linear member 2 in a parallel portion or a state close thereto is used. Oval or elliptical ring-shaped material 2 forming 2
A rectangular ring-shaped material 20a having a zero or parallelogram shape can be adopted.
0a is easily set and held by forming a holding portion for holding an intermediate portion of the ring-shaped material 20 or 20a on the split mold member for obtaining the block 10 as described above, and as an accurate product. Since it can be obtained, the connecting wire is not sagged by the pseudo rock material at the time of construction and does not deform even after installation, so it is obvious that a stable construction state can be secured. It is needless to say that since the connecting linear material can cope with some deformation, it can sufficiently cope with unevenness during normal construction.

As shown in FIGS. 4 to 6 in place of the ring-shaped material 20 or 20a as described above, FIG.
In FIG. 6, two linear members 19 and the like are set particularly over three or more blocks 1. In FIG. 5, a steel material 21 having a rectangular cross section or similar is arranged between pseudo rock materials, and in FIG. A high-strength steel material 22 can be arranged and employed between the pseudo rock materials, and furthermore, these connecting members 20, 20a, 1
9, 21, and 22 can be appropriately used together.

Further, the block 10 may be made of a dense cross-section structural material, but in some cases, as shown in FIG. Even in the air, it becomes a habitat for insects, crustaceans, etc., and the aquatic plants and grasses take root early to restore the natural landscape and prevent the outflow of sediment due to flooding by rooting. In addition, as shown in FIG. 8, the whole is made of the porous concrete pseudo-rock material 3, so that in the water, the water is purified by the contact oxidation by passing water, and further to the back soil layer 7 as shown in FIG. Water supply and the effect of ecological protection and greening restoration mentioned above can be improved and hastened.

The preferred revetment and revetment formation by the block 10 of the present invention as described above is as shown in FIG. 9 and is shown in FIG. 7 or FIG. 8 at the edge of a river or lake revetment. By adopting such a porous concrete pseudo-rock material 3 and installing it in the water or in the air, aquatic plants 12 are formed in the water and serve as hideouts and spawning grounds for small fishes. It will be home to insects, etc., and the space between artificial stones will be home to large fish and an evacuation site during floods. In the air, even if soil is laid between pseudo stones, in addition to the above effects, water is retained in the porous part and water is supplied to plants during the drought season in the summer, and excess water in the soil is removed during the rainy season. It drains immediately. At the shore, a riverside forest can be formed by planting vegetation 13 such as willows between pseudo stones.

Further, according to the present invention, there is shown a pseudo rock material 1 in which holes or hollow portions 8 and 8a are formed as shown in FIG. 10, FIG. 11 or FIG. When it is set to, it becomes a fish nest, and when it is provided in the air, it becomes a burrow for small animals, etc., and can be adopted as a product that takes into account ecological protection. That is, in such a case, the artificial rock material 1 can be made relatively large and the inner holes can be formed as the hollow portions 8 and 8a. 8b and 8c are formed, and a part or all of the hollow portions 8, 8a, 8b and 8c are formed as shown in FIG.
As shown in FIG. 3, the vegetation material layer 4 which is a vegetation roll 4a, a vegetation bag 4b, or a vegetation pot 4c formed of natural fibers such as coconut can be formed. Vegetation, reeds and cattails are vegetated and willow trees are used to cover the water's edge with green, creating a natural landscape.
In the air, early planting can be achieved by planting commercially available potted seedlings or by mixing seeds and fertilizer in the vegetation material. Alternatively, as shown in FIG. 14, a part or the whole of the pseudo rock material 1 may be formed as the porous concrete pseudo rock material 3 and the hollow portions 8, 8a, 8b or 8c are formed, and water purification, water retention, etc. Together with this, the effect can be further improved.

Some examples of the constructions formed by appropriately employing the block 10 of FIGS. 10 to 14 are shown in FIGS.
6, the underwater cavities 8 and 8a serve as fish nests, and the horizontal holes 8b serving as shelters serve as passages for fish and other underwater creatures 5 communicating with the gaps between the blocks. By layering the vegetation material layer 4 on the hollow portion 8c, reeds, aquatic plants 12, and the like grow, forming a waterfront friendly to the ecosystem. In addition, by installing a stake or other fixing member 18 in the penetrating cavity 8c, it becomes a resting place for water birds and the like underwater, and becomes a resting place for fish and shellfish as a stagnation place by weakening the flow velocity. It contributes to the stability of the block 10 on the surface and riverbed. In the air, they serve as shelters and dwellings for small animals, and because the soil between the pseudo-rocks enters the cavity and involves the roots, it prevents runoff due to floods and the like. In addition, by providing a vegetation material layer or inserting a willow or the like into a vertical through hole, a natural-friendly seawall can be formed early.

FIGS. 17 to 20 show a water-proof sheet material 6 for preventing sand from penetrating into a dike or a sand-prevention plate for preventing run-off due to suction or the like of back soil as described above. A specific example and the state of construction are shown for a state in which is attached. That is, the block 10 as described above according to the present invention is typically represented in FIGS.
1 is attached to the sheet material 6 in FIG.
7 and FIG. 18, and the state in which the block 10 shown in FIGS. 8 to 12 is attached to the sheet material 6 is as shown in FIG. 19, and in any case, the sheet material 6 is at least one side of the block 10. As shown in FIG. 20, it is set such that the side 10e of the adjacent block 10a is overlaid and placed on such a wide protruding portion 16 as the overlap allowance. Accordingly, the setting construction state in which the blocks 10, 10a are overlapped and connected to each other via the sheet material 6 to prevent the joint portion from being weakened can be easily formed.

In the above-described structure, a metal member such as steel is used as each of the connecting linear members 2 including the two linear members 19 and the ring members 20 and 20a and the connecting protrusions 11. It is clear that the rust-proofing treatment such as aluminum coating or galvanizing is particularly preferable. However, it is clear that the present invention is not limited to only such steel-based materials, and even in synthetic resins such as plastics, for example, polyethylene terephthalate, polybutylene terephthalate, polyphenylene oxide, and polycarbonate are equivalent to piano wires. Or 20 more
A tensile strength such as 00 to 10000 N / mm ² is obtained. By adopting such a member made of a synthetic resin, a product having excellent strength and corrosion resistance can be obtained. A manufacturing method using a nozzle or the like is adopted.

According to the present invention as described above, a plurality of convex pseudo-stones or pseudo-rock materials positioned while maintaining a gap are connected by connecting wire members overlapping in the thickness direction. In a structure in which a heavy artificial stone or pseudo-rock material is connected and arranged, a thickness-wise connecting linear material positioned at an appropriate distance in the thickness direction and overlapping is bent by the weight of the artificial stone or artificial rock material. The action to be deformed is mutually suppressed, so that even when handled or set on a foundation, the properties as a plate-like block are maintained, and the handling and installation operations are performed by suppressing the contact between pseudo stones or pseudo rock materials. In addition, the deformation of the block such as when the object moves on the base portion or the upper surface of the block is restricted even after the construction.

Since the ring-shaped body is used as the overlapping connecting linear member in the thickness direction, the overlapping connecting linear member is set as an integral member at the time of forming a pseudo stone or a pseudo rock material, and the set of connecting linear members is set. At the same time, it is easily bonded and integrated into each pseudo rock at the bent parts at both ends,
Further, the position and the dimensional relationship in the thickness direction are always kept accurately.

By arranging the linear connecting linear members in three or more pseudo-rock materials in an overlapping state in the thickness direction, it is easy to dispose the connecting linear members over many pseudo-stones or pseudo-rock materials. In addition, it is possible to easily obtain a concrete revetment or a revetment block on which a connecting linear material is disposed.

By providing the connecting projections bent in the height direction at the corner portion or the peripheral side portion, the block provided with the connecting projections together with the connecting linear material as described above can be easily manufactured. In addition, in the case where the blocks obtained in this way are connected in a plane, it is possible to carry out the construction effectively responding to the uneven deformation of the set area between the blocks.

A part or all of the artificial stone or the artificial rock material is made into a porous concrete part to obtain a water permeability and thereby purify water, to obtain a water supply to the back soil layer, and to further provide vegetation and the like. And obtain a contact purification effect between gravel.

By forming a hollow lumen communicating with the convex artificial stone or artificial rock material to the outside, a passage for fish and other aquatic organisms communicating with the gap between the blocks is formed, and the soil or the like is filled or deposited. Alternatively, the vegetation material layer is layered or filled to form a vegetation formation part in water or in the air, and a stable construction can be obtained even on a slope as a fixing structure using a pile or other fixing member.

It is to be noted that one or more vegetation roll materials or vegetation pots or vegetation bag members formed of natural fibers such as coconut are integrally disposed on a pseudo stone or a pseudo rock material so that various kinds of vegetation can be preferably set. Get a life.

The connecting wire of any of the concrete revetment or revetment blocks as described above is provided as a steel wire or a steel material, so that the strength is excellent, the workability suitable for the block body is provided, and the rust prevention is further provided. Or, anticorrosion processing is appropriately performed to obtain sufficient durability.

A sandproofing plate or a water-blocking sheet having a wide projecting portion which partially projects from the bottom surface of the above-mentioned concrete revetment or revetment block by an overlap allowance for construction from the bottom surface is integrally formed. A sandproof plate or a water-blocking sheet is provided by mounting, and the required area is effectively connected and integrated using the sand-proof plate or the water-blocking sheet, so that a sufficiently stable target construction can be easily and appropriately formed. .

By continuously setting any concrete revetment or revetment block as described above on the slope and the riverbed, it is effective as a stable revetment and revetment integrating the entirety from the slope to the riverbed. Let it form properly.
