[0011]

According to the first aspect of the present invention, by using the civil engineering block on the construction surface, the pedestal that covers the construction surface can substantially function as a revetment, floor protection, and wave-dissipating function. On the other hand, the civil engineering block can be easily manufactured by utilizing the characteristics of concrete (using the uncured state and the curing stage) while ensuring high reliability regarding strength. Further, since the wood is arranged at least around the pedestal, at the stage of use after completion, the wood can be used to blend the civil engineering block with the surrounding natural landscape without feeling uncomfortable. Natural trees themselves can be contributed as a nutrient source for seaweed, etc., and a rich sea can be created. Of course, in the civil engineering block, the concrete pedestal occupies most of the civil engineering block and shows the character as a heavy object, and the same weight stability as before is ensured. The stones are in harmony with the surrounding natural landscape, and the voids in each stone secure a habitat for insects, fish, shellfish, etc.

Further, since the wood constitutes a wooden frame for accommodating the pedestal, not only the wooden frame can be used as a mold to manufacture the pedestal, but also the wooden frame as the mold is used because of its structure. It is possible to save the labor of demolding while keeping the wooden frame as a means to harmonize with the surrounding environment. Furthermore, structurally, after using the wooden frame as a formwork,
Since it can be used as it is without demolding, unlike the usual case where the use and demolding of the formwork is performed, it is possible to smoothly and sequentially manufacture the civil engineering block without being limited by the number of formwork. Become. Furthermore, because of its structure, the wooden frame can be used as a mold, which makes it possible to easily adjust the size, unlike a normal steel mold, and to easily adjust the weight of the civil engineering block. You can do it.

Further, since the flexible sheet mold is interposed between the wooden frame and the pedestal, not only the wooden frame but also the flexible sheet mold is used as the frame to mount the pedestal. It will be possible to form reliably. Of course, even if the flexible sheet formwork disappears due to long-term use after the start of use, it does not affect the revetment, the seawall, and the wave-dissipating function.

Further, since the wooden frame is formed in the shape of a cross girder, the habitat space for fish and the like can be accurately secured by the gap based on the shape of the cross girder of the wooden frame. On the other hand, even if this wooden frame is in the shape of a cross girder, since the flexible sheet mold is built in the interior, the flexible sheet mold will receive concrete and ensure the pedestal. Will be able to be formed.

Further, since the side surface portion of the pedestal is projected together with the flexible sheet form frame so as to be inserted into the gap of the wooden frame, not only the friction between the side surface portion of the pedestal and the wooden frame but also its The engagement relationship can be established based on the fact that the side surface portion of the pedestal enters into the gap of the wooden frame, and the integration between the wooden frame and the pedestal can be further enhanced. Moreover, in order to obtain this engagement relationship, it is possible to effectively use the gap between the wooden frames, the fluidity of the concrete in the manufacturing stage, and the flexible sheet mold.

According to the invention of claim 2, on the construction surface,
A large number of civil engineering blocks are laid, and each of the civil engineering blocks has a concrete pedestal housed in a girder-shaped wooden frame such that the perimeter of the pedestal is surrounded, and between the wooden frame and the pedestal. The flexible sheet mold frame is interposed in the above, and the side surface portion of the pedestal is projected together with the flexible sheet mold frame so as to be inserted into the gap of the wooden frame. By using the civil engineering block according to 1) as a construction surface, it is possible to obtain a civil engineering structure structure that exhibits a sea wall, a sea floor, a wave-dissipating function, and the like.

According to the third aspect of the present invention, as the civil engineering block, the concrete pedestal is provided in the cross-shaped wooden frame,
The pedestal is housed so as to be surrounded, and a flexible sheet mold is interposed between the wooden frame and the pedestal, and a side surface portion of the pedestal is formed together with the flexible sheet mold. , The thing which projects so that it may enter into the clearance of the said wooden frame is prepared, and since the said block for civil engineering is installed on a construction surface as it is, the civil engineering structure structure according to said claim 2 can be constructed only by the said method. Or, in the civil engineering block on the construction surface, a wooden frame is left as a formwork for forming a pedestal, and while utilizing it as a means of harmony with the surrounding environment, demolding at the time of manufacturing the civil engineering block It will be possible to save the trouble of.

According to the fourth aspect of the present invention, there is prepared a cross-shaped wooden frame in which the flexible sheet mold is installed along the inner surface, and then the flexible sheet mold is placed in the flexible sheet mold. By filling with concrete, by this method, a concrete pedestal is housed in a double girder-shaped wooden frame so that the periphery of the pedestal is surrounded, and a flexible sheet is provided between the wooden frame and the pedestal. It is possible to specifically manufacture the civil engineering block in which the molding frame is interposed.

In this case, the civil engineering block manufactured by the invention according to claim 4 can be simply manufactured structurally similarly to the invention according to claim 1, while the concrete pedestal provides weight stability. , It is possible to secure the sea wall, the sea floor function, etc., and the wooden frame makes it possible to achieve harmony with the surrounding natural environment.

According to the fifth aspect of the present invention, there is prepared a wooden frame in which the flexible sheet mold is built along the inner surface thereof, and then the flexible sheet mold is formed. The concrete block is filled with concrete, and the concrete is swelled so as to enter the gap of the wooden frame together with the flexible sheet mold. Therefore, the civil engineering block according to claim 1 is concretely formed by the method. Can be manufactured in a simple manner. In addition, since the wooden frame and the like are used without removing the mold, unlike the usual case where the use and demolding of the frame are performed, the civil engineering works can be smoothly and sequentially performed without being limited by the number of the frame. Block can be manufactured. Further, since the wooden frame is used as the form, the size can be easily adjusted unlike the ordinary steel form, and the weight of the civil engineering block can be easily adjusted. .

According to the sixth aspect of the invention, since the wooden frame is fixed on the bottom plate before the flexible sheet formwork is filled with the concrete, the concrete injection is reliably received by the bottom plate. In addition, it is possible to manufacture the civil engineering block with the bottom plate preliminarily floated, and facilitate the transportation work (roping, lifting work, etc.) of the civil engineering block after the manufacturing.

In this case, in the civil engineering block manufactured by the invention according to claim 6, the wooden frame is fixed on the bottom plate, and the pedestal is housed in the wooden frame on the bottom plate. Not only the friction and engagement between the wooden frame and the wooden frame but also the weight of the pedestal as a heavy object can be used to prevent the wooden frame from coming off the pedestal through the bottom plate.

It is formed by pebbles, crushed stones, etc. to have a certain thickness. Based on this backfill layer 3, the ground bearing capacity and bearing capacity are strengthened, and the permeated water from the surface slope and the leached water from the slag body ( It is supposed to secure the effect as a filter against sand particles and to reduce the return wave (return flow) to reduce scour.

As shown in FIGS. 1 to 4, the civil engineering block 4 includes a wooden frame (wood) 5, a concrete pedestal 6 provided in the wooden frame 5, and a plurality of pedestals provided on the upper surface of the pedestal 6. It is roughly composed of natural stones 7 and.

The wooden frame 5 is, as shown in FIGS. 3 and 4,
The machined logs 8 made of square wood are assembled alternately and formed in a cross beam shape, and the machined logs 8 at the respective intersections at the four corners are connected by penetrating a long bolt and screwing nuts thereto. . As a result, the wooden frame 5
A quadrangular shape when viewed from above (in this embodiment, one side is 200
While defining an internal space 9 of about 0 mm square),
A gap 10 for communicating the internal space 9 with the outside is to be formed in a portion of the stacked steps of the processed logs 8 which does not exist. In addition, in FIG. 2 and FIG. 3, a series of fasteners constituted by the long bolts, nuts and the like are indicated by reference numeral 11.

As shown in FIGS. 3 and 4, a cloth mold 12 as a flexible sheet mold is built in the wooden frame 5. The cloth frame 12 is made of cloth such as chemical fiber,
It is formed in a bag shape, and the side surface of the cloth mold 12 is accommodated along the inner surface of the wooden frame 5, and the upper opening thereof constitutes the wooden frame 5 with the fastener 13 having a substantially U-shaped cross section. It is fastened to a processed log 8. In addition, in FIG. 3, in order to make the wooden frame 5 easy to see, a cross section of the cloth frame 12 is taken,
Illustration of the fastener 13 is omitted.

The pedestal 6 is, as shown in FIGS. 3 and 4,
It is housed in the cloth mold 12 inside the wooden frame 5 and occupies the entire inner volume of the wooden frame 5. The side surface 6a of the pedestal 6 swells to some extent at a position where a gap 10 between the wooden frame 5 (between the upper and lower processed logs) exists, and the bulge portion 1
6 enters the gap 10 together with the cloth frame 12, and the side surface 6a of the pedestal 6 and the wooden frame 5 are engaged with each other to prevent the wooden frame 5 from coming off the pedestal 6 reliably. On the other hand, the upper surface 6b and the lower surface 6c of the pedestal 6 form flat surfaces.

The plurality of natural stones 7 are fixed on the entire upper surface 6b of the pedestal, as shown in FIGS.
Each natural stone 7 has a diameter of about 300 to 500 mm (preferably 400 mm).
Is firmly attached to the wire net 17 corresponding to the pedestal upper surface 6b (square in plan view) on one side through the mounting washer 18 and the driving anchor 19, and the wire net 17 and its The lower part of each natural stone 7 (1 / of the whole
3 or less) is embedded in the concrete pedestal 6. As a result, the concrete forming the pedestal 6 wraps the constituent wire rods of the wire net 17 and the concrete wire forming the pedestal 6 and the constituent wire rods of the wire net 17 are engaged with each other. Even if 2/3 or more of the natural stones 7 and the pedestal 6 are projected upward from the pedestal upper surface 6b, the natural stones 7 and the pedestal 6 are firmly integrated. In this case, as the wire net 17, various things such as a rhombic wire net and a hexagonal wire net can be used. However, instead of the wire net 17, a synthetic resin net, a carbon fiber net, a mesh, various rebars, a steel frame (rebar-shaped rebar, Lattice-shaped reinforcing bars, etc.) may be used as appropriate.

In the present embodiment, as shown in FIG. 4, legs 31 are provided at the lower portions of the four corners of the wooden frame 5, respectively. Each of the legs 31 is formed of a short square bar (for example, a square end face having a side of about 125 mm and a length in the extending direction of about 400 mm) (FIG. 4 shows the end face). The portion 31 is fixed to the lower portions of the four corners of the wooden frame 5 by using the fastener 11 so that the wooden frame 5, the pedestal 6 and the like are floated from the backfill layer 3. This is taken into consideration when the flat lower surface of the pedestal 6 is placed on the uneven backfill layer 3 as it is, so that the installation stability may be deteriorated (unstable), and this is solved. Therefore, the four legs 31 support the wooden frame 5, the pedestal 6 and the like at four points.

The civil engineering block 4 as described above is manufactured as follows. First, the cross-shaped wooden frame 5 (see FIG. 5) having the cloth mold 12 built therein and a natural stone holding unit 20 (see FIG. 6) holding a plurality of natural stones 7 are prepared. The cloth frame 12 is built in the wooden frame 5, and the upper opening of the cloth frame 12 is the fastener 1.
It is fastened to the wooden frame 5 with 3.

On the other hand, the natural stone holding unit 20 has a base 6
The plurality of natural stones 7 are evenly arranged on one surface side of the square-shaped wire net 17 corresponding to the upper surface 6b of each of the natural stones 7.
It is fixed to the wire net 17 using a mounting washer 18 and a driving anchor 19. In manufacturing the natural stone holding unit 20, a plurality of natural stones 7 having mounting holes (not shown) are prepared, and the plurality of natural stones 7 are arranged on the work surface with the mounting holes facing upward. Wire net 17 on natural stone 7
Cover. Then, the mounting washer 18 is directed onto the metal net 17 for each natural stone 7, and the insertion hole (not shown) of the mounting washer 18,
The anchor 19 is inserted through the mesh of the wire net 17 and the natural stone 7
The natural stones 7 and the wire nets 17 are integrated by driving them into the mounting holes. Of course, in this case, the driving anchor 19
Instead of the above, the natural stone 7 and the wire net 17 may be integrated by using an adhesive.

Next, as shown in FIG. 5, while placing the wooden frame 5 on the work soil surface, each leg portion 31 is embedded in the work soil (preferably sandy soil). This is because when the concrete is filled in the next step, the working soil surface is properly used as the concrete receiving surface without being hindered by the support structure based on the leg portions 31.

Next, in order to form the pedestal 6, as shown in FIG. 6, the cloth mold frame 12 in the wooden frame 5 is filled with concrete. In this case, from the viewpoint of securing the weight as much as possible, it is preferable to inject concrete so that bubbles are not formed inside as much as possible. Moreover, when pouring this concrete, a waste material such as steel slag may be added as a filling material. This allows waste to be sequestered and reduces the heavy weight of the waste.
It can be used as the weight of the pedestal 6. Of course, in this case, it is also possible to add iron, silica, etc., which are deficient in seawater.

Next, in order to integrate the concrete in the wooden frame 5 and the natural stone holding unit 15, as shown in FIG. 6, before the concrete in the cloth frame 12 is cured, The natural stone holding unit 20 is inserted from the upper opening. At this time, the natural stone holding unit 20 is submerged in the uncured concrete while setting the wire net 17 below the plurality of natural stones 7 and the lower part of the wire net 17 and each natural stone 7 (1/3 or less of the whole). Are embedded in the uncured concrete, and 2/3 or more of each natural stone 7 is projected upward from the uncured concrete upper surface 6b. In this case, from the viewpoint of improving workability, the wire mesh 17
In consideration of the buoyancy of uncured concrete that acts on a plurality of natural stones 7 (including the buoyancy associated with changes over time (change in hardening degree)), the natural stone holding unit 20 is placed on the uncured concrete upper surface 6b in the formwork 13. It is preferable to set the natural stone holding unit 20 so that the natural stone holding unit 20 sinks only by the desired depth in view of the balance with the weight of the natural stone holding unit 20 just by placing it. Of course, considering the intensity of the waves,
The deeper the submerged amount of the natural stone holding unit 20 (the wire net 17), the deeper the submerged amount of the natural stone holding unit 20 (the wire net 17) becomes, so that the hardened concrete is held (engaged) with respect to the wire net 17 at the time of use. It is better to raise.

After that, the hardening of the uncured concrete in the wooden frame 5 is waited, and the production is finished.

Thus, the civil engineering block 4 has a physical engagement relationship between the concrete pedestal 6 and the wire net 17 (a relationship in which hardened concrete wraps the wire rods constituting the wire net 17).
Therefore, since the plurality of natural stones 7 (natural stone holding units 15) are held on the pedestal 6, it is possible to firmly hold the plurality of natural stones 7 (natural stone holding unit 15) on the pedestal 6. Instead, it is possible to easily and quickly obtain the strong holding of the concrete by utilizing the characteristics of the concrete (uncured state, hardening stage) at the time of production. In addition, it is possible to save the work of demolding while leaving the wooden frame 5 as a mold and making the most of the wooden frame 5 as a means to harmonize with the surrounding environment.

A large number of such civil engineering blocks 4 are arranged on the back-filling layer 3 in an appropriate positional relationship when constructing the gently sloping stud 1, as shown in FIG.
Pacing stones 22 are filled in the gaps 21 between the respective civil engineering blocks 4. In this case, it is preferable that the adjacent civil engineering work blocks 4 are connected to each other by using a connecting tool, and the upper part of the cloth form frame 12 is removed so that the wooden frame 5 is exposed. Is preferred.

Therefore, in the gentle slope 1 as described above, the construction surface 2 is the pedestal 6, the natural stone 7 on the pedestal 6, and in the present embodiment, the filling stone 2 filled in the cavity 21.
2 will also be covered by the pedestal 6, the natural stones 7 on the pedestal 6, the roughness of the filling stones 22 and the like, a revetment function (including revetment, root consolidation, etc.) The beach scour prevention effect will be demonstrated.

On the other hand, each of the civil engineering blocks 4 has a property of being a heavy object based on the concrete pedestal 6 and a preferable mode of connecting the civil engineering blocks 4 to each other, whereby the position retaining property of each of the civil engineering blocks 4 is maintained. (Weight stability) will be enhanced. Moreover, regarding the filling stones 22, the construction (the staggered arrangement) in which the neighboring civil engineering blocks 4 face each other between the civil engineering blocks 4 in each row means that the filling stones 2 are washed away (washed away). ) Will be suppressed. Therefore, this gentle slope 1
In the above, it is possible to surely exert the revetment and wave-dissipating functions also by the filling stones 22.

Of course, the natural stones 7 on the pedestal 6 and the filling stones 22 filled in the voids 21 are in harmony with the surrounding natural landscape, and the voids of the natural stones 7 etc. are insects, fish and shellfish. It also serves as a habitat for people such as.

In each of the embodiments, the same components as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the second embodiment shown in FIG. 7, the natural stone holding unit 20 according to the above embodiment is used as an embedding material.
Instead of, the anchor 23 is used for each natural stone 7. The anchor 23 has one end fixed to the natural stone 7 and the other end bent to ensure resistance to the hardened concrete. As a result, the natural stones 7 can be easily and accurately attached to the pedestal 6 with the anchors 23, and the anchors 23 of natural stones with anchors can be individually embedded when the concrete is not cured,
The arrangement position of each natural stone 7 with respect to the upper surface of the pedestal 6 can be freely determined. Of course, also in this case, the leg portions 31 according to the first embodiment may be provided at the lower portions of the four corners of the wooden frame 5 to form a four-point support structure.

The third embodiment shown in FIG. 8 shows a modification of the arrangement of the civil engineering block 4 according to the first embodiment. In the third embodiment, as shown in FIG. 8, the civil engineering blocks 4 are arranged in order so as to form a continuous row in the vertical and horizontal directions.
Pacing stones 22 are filled between them. As a result, the revetment function and the like can be exerted even in this arrangement structure.

The fourth embodiment shown in FIGS. 9 to 11 shows a block for civil engineering which is suitable not only for wave-dissipating function but also for floor protection and root consolidation. In this civil engineering block 4, a wooden frame (a wooden frame part or a basic wooden frame part) 40 and a wooden frame (a wooden frame part or a stacked wooden frame) 41 are stacked in a plurality of stages (two stages in this embodiment). Thus, the pedestal 6 is housed in the wooden frame 40 in the lower stage, and the filling stones 42 are filled from above the pedestal 6 in the wooden frame 40 to the wooden frame 41 in the upper stage.

That is, in the lower wooden frame 40, as in the first and second embodiments, as shown in FIG. 11, a box-shaped cloth mold (for example, a non-woven cloth frame) 12 is folded.
(In the present embodiment, a plurality of U-shaped fasteners are fixed at a plurality of positions by driving it into the inner surface of the wooden frame via the cloth mold 12), and the concrete inside the cloth mold 12 is After being injected, the pedestal 6 is housed and held in the wooden frame 40 as in the above embodiment.

On the other hand, the upper wooden crate 41 does not have the cloth mold 12 built therein, and the upper wooden crate 41 is connected to the lower wooden crate 40 in a stacked state. In this connection, as the connecting tool, the first
A series of fasteners 11 according to the embodiment are used as common ones, and long bolts of the fasteners 11 penetrate through four corners of upper and lower wooden frames 40 and 41, and upper and lower ends thereof are nuts. It is to be tightened. Of course, as another connecting method, the wooden frame 40 in the lower stage is connected to the series of fasteners 1
After assembling with No. 1, another connecting tool such as a wire may be used to connect the upper wooden frame 41 to the lower wooden frame. Inside the upper wooden crate 41 and the lower wooden crate 40 (in the lower wooden crate 40, the space above the pedestal 6) are filled with the filling stone 42.
Are engaged with each other and also with the wooden frame 41, and are integrated with the wooden frame 41.

Will be used as. Of course, also in this case, the leg portions 31 according to the first embodiment may be provided at the lower portions of the four corners of the wooden frame 40 to form a four-point support structure.

Therefore, in the civil engineering block 4 according to the fourth embodiment, while the pedestal 6 is stored and held in the wooden frame 40, the filling stone 42 is filled in the wooden frame 41 on the pedestal 6 or the like. Therefore, without the need for any special fixing means, the same effects and advantages as those of the first and second embodiments are ensured (weight stability is secured and revetment (including seawall and root consolidation), wave-dissipating function, etc. are secured. In addition, it is possible to obtain a structure that can be rapidly and easily manufactured, etc., and moreover, by adjusting the number of the wooden frames 41, it is possible to make the height of the civil engineering block desired. Become.

The civil engineering block 4 according to the fourth embodiment as described above is manufactured as follows. First, concrete is poured into the cloth mold 12 inside the wooden frame 40 in the lower stage to form the pedestal 6 as in the first and second embodiments. This is because the main weight is secured in order to secure the weight stability. In this case, the formation of the pedestal 6 in the wooden frame 40 is
It may be performed after the wooden frame 40 is placed on the construction surface 2 in advance, or after the pedestal 6 is formed in a place other than the construction surface 2,
The wooden frame 40 holding the pedestal 6 may be transported to the construction surface 2. In the wooden frame 40 at this stage, in the series of fasteners 11, a nut is screwed to the lower end portion of the long bolt, and the upper end side of the long bolt is in a state of protruding from the four corners of the wooden frame 40.

The bent portion 5 on one end side of each opposing line portion 52 is configured by a connecting portion 54 that connects the other end side of 52 in a curved state.
3 enters the pedestal 6 to exert a retaining function, and the connecting portion 54 on the other end side of the opposing line portion 52 constitutes a hooking portion for connecting the civil engineering blocks 4 to each other. There is. In this case, the reinforcing bar 51 is set before the concrete is filled into the cloth mold 12 in the wooden frame 5, but at this time, the opposing line portion 52 of the reinforcing bar 51 is based on the spring property based on the substantially U shape. , The upper and lower processed logs 10 defining the gap 10 are engaged with each other in a biased state so that the reinforcing bar 51 can be easily set on the wooden frame 5. After that, after the concrete filling is completed and the concrete is hardened, on the one end side of the reinforcing bar 51, since the hardened concrete is also present between the opposite line portions 52, the expansion and contraction of the opposite line portions 52 is performed. The sex is regulated, and each rebar joins the pedestal 6 and the wooden frame 5. In addition, each natural stone 7 on the upper surface of the pedestal 6 is ⅔ of its vertical height.
The above projects from the upper surface of the pedestal 6, and the space between the natural stones 7 is preferable as a habitat space for plants and animals.

Such a civil engineering block 4 is not only used as a wave-dissipating block as shown in FIG.
As shown in FIG. 17, it is also used in rivers and the like for the purpose of bed protection, root consolidation, and the like. In addition, in FIG.
