As shown in FIGS. 1 to 4, the civil engineering block 4 includes a wooden frame (wood) 5, a concrete base 6 provided in the wooden frame 5, and a plurality of bases provided on the upper surface of the base 6. And a natural stone 7 of this type.

The wooden frame 5 is, as shown in FIGS.
The machined logs 8 made of square bars are alternately assembled to form a girder shape, and the machined logs 8 at the respective intersections at the four corners are connected by penetrating long bolts and screwing nuts to them. . Thereby, the wooden frame 5
A quadrangular shape (in this embodiment, 200 mm on a side)
A square around 0 mm)
A gap 10 where the internal space 9 and the outside communicate with each other is formed at a non-existent portion of the stacking step of the processing log 8. 2 and 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, the wooden frame 5 has a cloth mold 12 as a flexible sheet mold built therein. The cloth mold 12 is made of a cloth such as a 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 the processed log 8. In addition, in FIG. 3, in order to make the wooden frame 5 easy to see, the cross section of the cloth mold 12 is taken,
The illustration of the fastener 13 is omitted.

The pedestal 6 is, as shown in FIGS.
It is housed in the cloth mold 12 in the wooden frame 5 and occupies the entire inner volume of the wooden frame 5. The side surface 6a of the pedestal 6 slightly swells at the place where the gap 10 between the wooden frame 5 (between the upper and lower processing logs) exists, and the swelling portion 1
6 is inserted into the gap 10 together with the cloth mold 12, and the side surface 6 a of the pedestal 6 is engaged with the wooden frame 5 so that the wooden frame 5 is securely prevented from falling out of the pedestal 6. On the other hand, the upper surface 6b and the lower surface 6c of the pedestal 6 form a flat surface.

The plurality of natural stones 7 are fixed over the entire pedestal upper surface 6b 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 mesh 17 via a mounting washer 18 and a driving anchor 19 while being placed on one side of a wire mesh 17 (square in a plan view) corresponding to the pedestal upper surface 6b. The lower part of each natural stone 7 (1/1 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 of the wire mesh 17, and an engagement relationship is established between the concrete forming the pedestal 6 and the constituent wire of the wire mesh 17. Even if 2/3 or more project upward from the pedestal upper surface 6b, each natural stone 7 and the pedestal 6 are firmly integrated. In this case, as the wire mesh 17, various types such as a rhombus wire mesh and a turtle wire mesh can be used. Instead of the wire mesh 17, a synthetic resin net, a carbon fiber net, a mesh, various reinforcing bars, and a steel frame (a cross-shaped reinforcing bar, A lattice-shaped reinforcing bar or the like may be used as appropriate.

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

The civil engineering block 4 is manufactured as follows. First, the wooden frame 5 (see FIG. 5) in the shape of a girder 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 wooden frame 5 incorporates the cloth mold 12, and the upper opening of the cloth mold 12 is the fastener 1.
3 is fastened to the wooden frame 5.

On the other hand, the natural stone holding unit 20 is
A plurality of natural stones 7 are evenly arranged on one surface side of a square wire mesh 17 corresponding to the upper surface 6b of the
It is fixed to the wire net 17 using a mounting washer 18 and a driving anchor 19. In the manufacture of 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 a work surface with the mounting holes facing upward. Wire mesh 17 on natural stone 7

Next, as shown in FIG. 5, the wooden frame 5 is placed on the surface of the working soil, and the legs 31 are buried in the working soil (preferably sand). This is because the working soil surface can be accurately used as a concrete receiving surface without being hindered by the support structure based on the legs 31 at the time of filling the concrete in the next step.

Next, as shown in FIG. 6, concrete is filled in the cloth mold 12 in the wooden frame 5 to form the pedestal 6. In this case, from the viewpoint of securing the weight as much as possible, it is preferable to inject concrete so as not to form bubbles as much as possible. When pouring the concrete, a discarded material such as steel slag may be added as the filling material. This allows the waste to be sequestered and the heavy weight of the waste to be reduced.
The weight of the base 6 can be used. In this case, of course, iron or silica, etc., which is insufficient in seawater, can also be added.

Next, in order to integrate the concrete in the wooden frame 5 with the natural stone holding unit 15, as shown in FIG. 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 with the wire net 17 being lower than the plurality of natural stones 7, and the wire net 17 and the lower part of each natural stone 7 (1/3 or less of the whole). Are embedded in the uncured concrete, and more than two thirds of each natural stone 7 projects upward from the uncured concrete upper surface 6b. In this case, from the viewpoint of improving workability, the wire mesh 17 is used.
In consideration of the buoyancy (including the buoyancy due to the aging (change in the degree of hardening)) of the uncured concrete acting on the plurality of natural stones 7, 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 to the desired depth by simply placing the natural stone holding unit 20 on the balance with the weight of the natural stone holding unit 20. Of course, considering the intensity of the waves,
The more the waves are expected to be used at places where the waves are expected to be strong, the deeper the sinking amount of the natural stone holding unit 20 (the wire mesh 17) becomes, and the strength of holding (engaging) the hardened concrete on the pedestal 6 with the wire mesh 17 during use. Should be increased.

Thereafter, the hardening of the unhardened concrete in the wooden frame 5 is awaited, and the production is completed.

As described above, the civil engineering block 4 has a physical engagement relationship between the concrete pedestal 6 and the wire mesh 17 (a relationship in which the hardened concrete wraps the constituent wires of the wire mesh 17).
Accordingly, since the plurality of natural stones 7 (natural stone holding units 15) are held on the pedestal 6, the plurality of natural stones 7 (natural stone holding units 15) can be firmly held on the pedestal 6. In addition, at the time of production, it is possible to easily and quickly obtain the strong retention of the concrete by utilizing the properties of the concrete (unhardened state, hardened stage). In addition, the wooden frame 5 is left as a mold, and the wooden frame 5 can be used as a means for harmonizing with the surrounding environment, and the trouble of removing the mold can be saved.

A large number of such civil engineering blocks 4 are arranged on the backfill layer 3 in an appropriate arrangement as shown in FIG.
The gaps 21 between the respective civil engineering blocks 4 are filled with filling stones 22. In this case, it is preferable to connect the adjacent civil engineering blocks 4 with each other using a connecting tool, and to remove the upper part of the cloth mold 12 so that the wooden frame 5 is exposed. Is preferred.

Accordingly, in such a gentle slope 1, the construction surface 2 is composed of the pedestal 6, the natural stone 7 on the pedestal 6, and in the present embodiment, the filling stone 2 filled in the void 21.
2 and the base 6, the natural stones 7 on the pedestal 6, the roughness of the filling stone 22, etc., the revetment (including the protection of the slabs, the consolidation, etc.), the wave breaking function, The effect of preventing scouring of the beach is exhibited.

On the other hand, the position of each of the civil engineering blocks 4 is maintained by the nature of the heavy weight based on the concrete pedestal 6 and the connection of the civil engineering blocks 4 in a preferred embodiment. (Weight stability) will be improved. In addition, with regard to the stuffing stones 22, the configuration in which the adjacent rows of civil engineering blocks 4 face each other between the civil engineering blocks 4 in each row (the staggered arrangement) is such that the stuffing stones 2 are washed away (washed out). ). For this reason, this gentle slope 1
In this case, the seawall and the wave breaking function can be surely exerted even by the filling stone 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 scenery, and the voids of the natural stones 7 are insects, fish, shellfish, etc. It is also a habitat for such as.
