[0010]

According to the first aspect of the present invention, a concrete layer covers the slope, and the concrete layer and
The plurality of stones and the wall material on the surface side are integrated with each other in such a manner that the concrete layer and each stone sandwich the wall material based on the anchor being embedded and fixed in the concrete layer. For this reason, it is possible to obtain a strong brickwork type civil engineering structure. Further, at the time of construction, the stone can be stably piled up by using the wall material (slope) on the surface side of the wall material by standing and holding the wall material, thereby forming a concrete layer. Concrete (unhardened) can be independently filled between the wall material and the slope without wrapping each stone in more than half and waiting for its curing. For this reason, while obtaining a strong brickwork type civil engineering structure, while improving its construction workability,
The construction period can be shortened.

According to the second aspect of the present invention, the concrete layer covers the slope, and a plurality of stones are present on the surface side of the concrete layer. You can get it. Also, at the time of construction, the wall material is raised and held, and on the surface side of the wall material, stones are piled up by using the wall material (slope), and based on the connection relationship between the anchor and the wall material,
Each stone can be held on the wall material via an anchor, and concrete (unhardened), which will form a concrete layer, must not be wrapped more than half of each stone and wait for curing. Instead, it can be filled independently between the wall material and the slope. For this reason,
The construction workability can be improved and the construction period can be shortened, while obtaining a strong brickwork type civil engineering structure.

According to the third aspect of the present invention, since the wall material is formed by adding a plurality of wall material elements, the wall material can be expanded according to the size of the slope. This makes it possible to easily adapt to the size of the civil engineering structure to be built.

According to the fourth aspect of the present invention, since the wall material has a lattice shape, the anchor provided on each stone can be inserted into the wall material and held by the wall material. In addition, it is possible to easily connect the anchor of each stone to the wall material, and it is possible to further improve construction workability. In addition, at the time of construction, the concrete that has flowed out to the surface side of the grid-like wall material is used while preventing the flow of concrete forming the concrete layer from flowing out in large quantities due to the piled stones. After the hardening, the hardened concrete portion is locked to the wall material, so that the concrete layer and the wall material can be integrated.

According to the fifth aspect of the present invention, since the wall material is made of a reinforcing bar or a wire mesh, the same effect as in the fourth aspect can be obtained by using a concrete lattice-like wall material. Can be obtained.

According to the invention described in claim 6, since the filling material is packed between the stones, the piled state of the stones can be stabilized at the time of construction and after the construction. . In addition, when the wall material has a communication portion that connects the front side and the back surface side of the wall material, such as a grid, the concrete (concrete layer flowing out) to the front side of the grid material, etc. The hardened concrete part can be locked to the wall material after the hardening of the unhardened state (before it is formed), while the pile of stones, together with the piled stones, can cause a large amount of concrete to flow into the wall. It is possible to effectively suppress the outflow to the surface side of the material.

According to the invention described in claim 7, since the padding is packed between each stone and the wall material and between the stones, the length of the anchor during and after construction is set. In consideration of the size, the stones can be stacked while being in contact with (supporting and guiding) the filling material layer filled between the stones and the wall material. Combined with regulating the movement of the stones, it is possible to stabilize the piled state of each stone. Along with this, it is also possible to increase the length of the anchor to some extent to improve the workability of connection to the wall material. In addition, since the padding layer packed between each stone and the wall material constitutes a perforated space, the perforated space can be used as a habitat for various species.

According to the eighth aspect of the present invention, since the filling material contains vegetation sandbags, plants can be grown and greened, and a civil engineering structure in harmony with nature can be obtained.

According to the ninth aspect of the present invention, the civil engineering structure according to the first aspect can be constructed by the method. The work efficiency can be improved and the work period can be shortened.

According to the tenth aspect of the present invention, the civil engineering structure according to the second aspect can be constructed by the method. The work efficiency can be improved and the work period can be shortened.

According to the eleventh aspect of the present invention, the same effect as that of the fourth aspect can be obtained by the method.

According to the twelfth aspect of the present invention, the stones are stacked in a plurality of predetermined steps, and the concrete is filled up to the stacked height of the predetermined plurality of stones. Since it is sequentially repeated as a partial area construction process, the weight burden of the cantilevered wall material is reduced by the support of the concrete and the wall material is not deformed, and it is possible to reliably construct a masonry type civil engineering structure. Become.

According to the thirteenth aspect of the present invention, the transition to the new construction step is performed after the concrete filled before the new construction step is cured. Since the timber is supported, it is possible to more reliably construct a masonry-type civil engineering structure without deforming the cantilevered wall material.

According to the fourteenth aspect of the present invention, when the stone and the concrete reach the vicinity of the upper end of the wall material, a wall material element to constitute the wall material is newly added to the upper end of the wall material. By adding, the wall material can be reliably expanded upward, and can be adapted to the scale of the civil engineering structure to be constructed.

According to the fifteenth aspect of the present invention, the concrete layer covers the slope, and the wall material and each stone connected to the wall material are integrated with the concrete layer. As a result, it is possible to obtain a strong brickwork type civil engineering structure. In addition, at the time of construction, construction will be performed in the order of formation of concrete layer (hardened), laying and fixing of wall material, connection of each stone, and concrete (uncured) that will form concrete layer There is no need to wrap each stone more than half and wait for the concrete to cure. For this reason, by this method, while obtaining a strong brickwork type civil engineering structure, the workability of the work can be improved and the work period can be shortened. Moreover, since the wall material is fixed to the hardened concrete layer, it is not necessary to fix the wall material to the foundation material in front of the lower part of the slope.

According to the sixteenth aspect of the present invention, when the stones are stacked on the surface side of the wall material, the padding material is packed between the stones. Can be obtained.

According to the invention as set forth in claim 17, when the stones are stacked on the surface side of the wall material, the distance between each stone,
In addition, since the filling material is filled between each stone and the wall material, the same operation and effect as those of the seventh aspect can be obtained by this method.

According to the eighteenth aspect of the present invention, prior to the filling of the concrete, the sheet for suppressing the flow of the concrete is laid on the surface of the wall material. Accordingly, it is possible to suppress a large amount of concrete from flowing out to the surface side of the wall material, and it is possible to accurately form a concrete layer.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a stonewall type seawall (civil engineering structure) 1 according to the first embodiment. In this revetment 1, a foundation concrete 3 as a base material is provided in front of a lower part of the slope 2, and the upper surface of the foundation concrete 3 is attached to the slope 2 so as to be substantially perpendicular to the slope 2. It is inclined so that it goes downward as it approaches. A groove 4 is formed on the upper surface of the foundation concrete 3, and the groove 4 has a relatively deep seawall 1
(In the direction orthogonal to the plane of FIG. 1).

The grooves 4 of the foundation concrete 3 are
As shown in FIG. 5, the lower end of the wire mesh 5 as the wall material is fitted and held. The wire mesh 5 is erected along the slope 2 while keeping its mesh surface separated from the slope 2 by a predetermined distance based on the fitting and holding in the groove 4.
A space 6 having a predetermined length is to be formed therebetween. In this case, the wire mesh 5 for the foundation concrete 3
It is preferable that the holding of the lower end portion is further reinforced by another fixing means. The wire netting 5 has a mesh as is known, and its strength is such that it does not deform (do not bend) even when natural stones are stacked in a plurality of stages in the vertical direction.

As shown in FIG. 1, a net (sheet) 7 is laid on the surface of the wire netting 5 (only a part is shown in FIG. 4). The net 7 has a finer mesh than the mesh of the wire mesh 5, and the fluidity (concrete, sand, etc.) of the concrete forming the concrete layer 8 described later is:
The purpose is to suppress excessive flow into the surface side of the wire mesh 5, and in addition to the net 7, a nonwoven fabric or the like is used.

As shown in FIG. 1, a plurality of natural stones (stones) 9 are stacked on the surface of the wire mesh 5 via a net 7 (a plurality of natural stones 9 are also arranged in a direction perpendicular to the plane of FIG. 1). 9 (see FIG. 4). Each natural stone 9 is integrally provided with an anchor 10, and the anchor 10 extends so as to be separated from the natural stone 9 by a certain length, and a tip end portion thereof is curled. The natural stones 9 are piled up using the inclined surface of the wire mesh 5 with the anchors 10 facing the wire mesh 5 side, and the anchors 10 of the natural stones 9 are stacked from the surface side of the net 7. Natural stone 9 is wire mesh 5
The net 7 and the wire mesh 5 until they come into contact with the mesh surface of
And has extended to the space 6 on the back side of the wire mesh 5.

As shown in FIG. 4, a filling material 11 is packed between the natural stones 9 on the surface of the net 7. The stuffing material 11 regulates the movement of each natural stone 9 so that the natural stones 9 are stably stacked. As the stuffing material 11, cracking stone, vegetation sandbags, or the like is used. In particular, when a vegetation sandbag is used as the filling material, in addition to the above functions, it is possible to grow plants and promote greening. In this case, a sufficient space (gap) can be provided between the natural stones 9 even if the packing material 11 is packed.
Is secured, and the space is used for the growth of plants, organisms, etc.
It is to be used as a habitat.

As shown in FIG. 1 between the wire mesh 5 and the slope 2
As shown in FIG. 1, a concrete layer 8 is provided. The concrete layer 8 is formed by filling concrete (unhardened concrete) between the wire mesh 5 and the slope 2, and the concrete layer 8 is formed on the foundation concrete 3 by the wire mesh 5 and the slope 2. And extends along the slope 2 with a relatively large thickness corresponding to the length between them.
In this concrete layer 8, the anchor 1 of each natural stone 9
0 is buried, and the anchor 10 is prevented from falling out of the concrete layer 8 due to the engagement relationship between the curled tip of the anchor 10 and the concrete layer 8. Sandwiches the wire mesh 5, and each natural stone 9, wire mesh 5 and concrete layer 8 are to be integrated. In FIG. 1, reference numeral 12 denotes a top concrete.

Next, a method of constructing the above-described stone-mason type revetment 1 (retaining wall) will be described. First, the foundation concrete 3 is formed at the lower front of the slope 2. This is because it functions as a base for stacking the natural stones 9 and a support for the concrete layer 8 and as a means for holding the wire mesh 5 upright.

Next, as shown in FIG. 2, the lower end of the wire mesh 5 is fitted and held on the foundation concrete 3. This is because the wire mesh 5 is raised and held to secure a guide surface (support surface) for stacking the natural stones 9 and a concrete filling space 6.

Next, after the net 7 is laid on the surface of the wire mesh 5, as shown in FIG. 3, the net 7 (wire mesh 5) is used as a guide surface and a support surface, and one or more natural stones 9 are used. For example, 3
Stack up). In the pile of natural stone, natural stone 9
The reason that the wire meshes 5 are not stacked all at once but are stacked one to a plurality of times is to prevent the wire mesh 5 in a cantilever state from being deformed. The reason why the net 7 (wire mesh 5) is used as a guide surface and a support surface for stacking the natural stones 9 is to obtain a somewhat stable stacking state under a constant and appropriate stacking inclination. In this case, the anchor 10 of each natural stone 9 is penetrated through the mesh of the net 7 and the wire mesh 5 and extended to the space 6 on the back side of the wire mesh 5, and each natural stone 9 is connected to the wire mesh 5 through the net 7. As a result, each natural stone 9 is not only stably piled up to some extent using the slope of the wire mesh 5 as a support surface and a guide surface, but also temporarily piles up the natural stone 9. Even if the piled state collapses, the anchor 10 will engage with the wire of the wire mesh 5 and the natural stone 9 will not fall down to the bottom of the slope 2. Therefore, in order to increase the stability of the piled state of the natural stones 9 based on the engagement relationship between the wire mesh 5 and the anchor 10, it is preferable to make the mesh of the wire mesh 5 as small as possible. still,
A plurality of natural stones 9 having the anchors 10 are lifted and conveyed to a predetermined construction site by using a crane or the like by using the curled tip of the anchor 10.

Next, as shown in FIG. 1, a filling material 11 is packed between the natural stones 9. This is because the movement of each natural stone 9 is regulated to enhance the stability of the stacked state of the natural stones 9. In this case, as described above, cracking stone, vegetation sandbags, and the like can be used as the filling material 11, but when vegetation sandbags are used, not only can the stuck state of the natural stones 9 be stabilized, but also Therefore, plant growth can be enabled and greening can be promoted.

Next, as shown in FIG.
Is filled with concrete (shown by a concrete layer 8 in FIG. 3). This is because the concrete layer 8 is formed on the slope 2. In this case, the concrete is filled after setting the formwork on the back side of the wire mesh 5, and the filling is performed up to the height at which the natural stones 9 are stacked. In order to prevent a large amount of concrete from flowing out to the surface side of the wire mesh 5 using not only the net 7 but also the natural stones 9, the concrete stones 9 correspond to the height of the piled natural stones. On the other hand, as for the concrete that has flowed out, the hardened portion is locked to the wire mesh 5 (to wrap the wire material of the wire mesh) after the hardening thereof, and the hardened portion is connected to the wire mesh 5. It is used for integrating with the concrete layer 8. In this case, of course, the concrete is filled uniformly after the concrete is poured by using a vibrator or the like.

When concrete is filled between the wire mesh 5 and the slope 2 as described above, the concrete wraps the anchors 10 extending from the respective natural stones 9. As a result, after the concrete is hardened, the curled tip of the anchor 10 and the hardened concrete are locked, and each natural stone 9 cooperates with the concrete layer 8 while holding the wire mesh 5 therebetween. 8 will be fixed.

A series of steps from the stacking of the natural stones 9 in a plurality of stages to the filling of the concrete are repeated as a partial area construction step, and such construction is performed until the top is reached. This is for performing a masonry type construction on the entire slope 2. In this case, the new construction process
Curing (hardening) of concrete in the previous construction process
I can wait and start. Wire mesh 5 by hardened concrete
To reliably prevent deformation (bending) of the wire mesh 5 in the cantilevered state. In such a construction, if the length of the wire mesh 5 becomes insufficient due to the large slope 2, a new wire mesh 5 is added by welding or the like.

When the construction of the partial area is repeated and the construction reaches the top, the top concrete 12 is poured and the entire process is completed.

Therefore, in the first embodiment, not only can a strong brickwork type civil engineering structure be finally obtained, but also the wire mesh 5 (slope), the filling material 11, the anchor 10, etc. The natural stone 9 can be stably piled up by using the concrete, and the concrete (uncured) is independently wrapped with the wire mesh 5 without wrapping each stone more than half and waiting for its curing. It can be filled between the slope 2. For this reason, while improving workability | operativity, it will be possible to shorten the work period.

FIG. 5 shows a second embodiment. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the second embodiment, the anchors 10 of the natural stones 9 in the piled state are not penetrated by the wire mesh 5, but the ends of the anchors 10 are connected by a connecting tool (a binding tool such as a wire, a shackle). Are connected to the wire net 5. In each of the natural stones 9, not only the split stone as the filling material 11 is packed between each of the natural stones 9, but also the split stone as the filling material 11 between each natural stone 9 and the wire mesh 5. The filling material layer 13 is formed. This is because each natural stone 9
Are brought into contact with each other to guide and support the natural stones 9 by the filler layer 13, and to use the porous space in the filler layer 13 as a habitat for various living things. In the present embodiment, the wire mesh 5 is provided with a locking tool 14, and the locking tool 14 is embedded in the concrete layer 8. Thereby, the wire mesh 5 is integrated based on the locking relationship with the concrete layer 8.

The construction method according to the second embodiment has basically the same contents as the first embodiment. First, the wire mesh 5 is erected on the foundation concrete 3, and then the wire mesh is On the surface side of 5, a stacking operation or the like taking into account the above-mentioned specific contents is performed, and then concrete is filled between the wire mesh 5 and the slope 2.

As a modification of the second embodiment, the structure is the second
Although it is the same as the embodiment, the construction method may be different. That is, first, a concrete layer 8 (hardened state) is formed on the slope 2, a wire mesh 5 is laid on the concrete layer 8 via an anchor, and each natural stone 9 is attached to the wire mesh 5.
The anchor 10 may be connected via a connecting tool, and the filler layer 13 may be formed between the natural stone 9 and the wire mesh 5 by the filler 11. Thereby, not only the same operation and effect as in the second embodiment can be obtained, but also the wire mesh 5 is fixed to the hardened concrete layer 8, so that the wire mesh 5 does not need to be erected on the foundation concrete 3.

Although the embodiments have been described above, the present invention includes the following. (1) As a stone, besides the natural stone 9, a pseudo stone is used. (2) Instead of the wire mesh 5, a reinforcing bar (such as a reinforcing wire mesh) is used. (3) The concrete layer and the stacked stone layers are formed by forming wall materials in various modes such as arranging reinforcing bars and the like extending in the vertical direction sequentially in the horizontal direction. Of course, in this case, if the continuity of the wall material is too good (when the ratio of the gaps, holes, etc. is large), the sheet such as the net 7 is wall-mounted to prevent the uncured concrete from flowing out. It is preferable to lay on the surface of the material. (4) The wall material (wire, plate, etc.) is made of resin.

It should be noted that the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what substantially corresponds to what is described as preferred or advantageous.
