DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a futon basket having a retaining wall formed by stacking up and down.

[0002]

2. Description of the Related Art Conventionally, a futon basket as shown in FIG. 5 has been used when a retaining wall is constructed for protection of a slope, such as a mountain, a valley, a road, a residential area, a river bank, or greening.
This futon basket is composed of a rectangular bottom net, a side net connected to each side of the bottom net, and a top net attached to the upper surface. The retaining wall is formed by arranging a plurality of fillers, such as stones and rubbles, in parallel with each other on the left and right sides and stacking them vertically or stepwise.

[0003] The above-mentioned futon basket is generally formed of a net material such as a diamond-shaped wire netting, and a net material having a different mesh size depending on the use or the type of filler is used.

When stacking the above-mentioned futon baskets when constructing the retaining wall, in order to prevent displacement of the upper and lower futon baskets and to increase the stacking strength, the futon baskets are passed through the overlapping portions of the upper and lower futon baskets. In some cases, piles are cast in such a way as to do. In this case, the piles are driven through at least three meshes, such as the top mesh and bottom mesh of the upper futon basket, and the top mesh of the lower futon basket. If the mesh positions of the baskets are displaced from each other, inconveniences such as the piles strikingly hitting the row lines of the wire mesh, being unable to be driven straight, or being deformed by the piles are likely to occur. If the mesh of the wire mesh is small, the casting is more difficult.

[0005] Another problem is that when installing the upper futon basket on the lower futon basket packed with stones,
When the position of the stuffed stone in the lower futon basket needs to be shifted slightly to improve the fit or when it is necessary to replenish new stones, the conventional futon basket is completely covered by the upper surface net. However, it has been very troublesome and difficult to adjust the position of the stuffing stone and replenish new stone from the top net.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to lay a pile so as to penetrate a plurality of stacked futon baskets, and to position a filled stuffing stone. An object of the present invention is to provide a futon that can easily and surely perform such operations in the case where adjustment is performed.

[0007]

In order to solve the above-mentioned problems, a futon basket according to the present invention comprises a rectangular bottom net, at least two side nets connected to each side of the bottom net, and a top net. Has a top net attached to the, in the top net, part of the portion that overlaps with the upper futon basket stacked,
It is characterized in that it partially has an opening formed by removing the net material.

[0008] The futon basket having the above configuration is filled with earth and sand, rubble and the like and stacked vertically. When a pile for connecting the upper and lower futon baskets is cast, the opening of the upper and lower futon baskets is used. By driving the stake into the position where
Since only one bottom net of the upper futon basket needs to be penetrated through the pile, the casting is very simple and can be driven vertically.

[0009] When the upper futon basket is placed on the stuffed lower futon basket, the stuffing stones in the lower futon basket are shifted in position to improve the filling or replenish new stones. If necessary, the work can be simply and reliably performed through the openings in the upper mesh.

[0010] Since the opening is formed only in a part of the upper surface net portion overlapping the upper futon basket, the upper futon basket is always completely covered by stacking the futon basket. Become. Therefore, the filling does not flow out through the opening. The opening of the uppermost futon basket may be closed by an appropriate means, but may be used as a space for tree planting. Alternatively, a normal futon basket having no opening may be used for only the top row.

In the present invention, the upper surface net may be formed of a plurality of net materials having different meshes.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of a futon basket according to the present invention.
Is a bottom net 2 having a rectangular shape, front and rear side nets 3a, 3a and left and right side nets 3b, 3b connected to each side of the bottom net 2.
3b and an upper surface net 4 attached to the upper surface. Each of these surface nets can be formed of a net material such as a rhombic wire net, a welding wire net, a turtle wire net, a synthetic resin net, etc. In the illustrated example, a rhombic wire net is used.

The futon basket 1 may be a plurality of stairs stacked as shown in FIG. 3, a vertically stacked stack as shown in FIG. 4, or a combination of both. The upper surface net 4 is partially provided with a rectangular opening 5 formed by removing the net material at a part of a portion overlapping with the upper futon basket 1. I have. A bone frame similar to the bone frame 6 attached to the outer periphery of the upper net 4 can be attached to the rim 5a of the opening 5.

The shape and size of the opening 5 and the position where the opening 5 is provided are arbitrary. In the case shown in FIG.
Although the inside of the upper surface net 4 is formed at a position surrounded by the net material, it may be formed at a position as shown in FIGS. FIG. 5A shows an example in which one end of the opening 5 is formed so as to reach a short side of the upper surface net 4, and FIG. 7B shows an example in which the opening 5 is formed at a position dividing the upper surface net 4 in the length direction. In FIG. C, the opening 5 is formed at a position that divides the upper surface net 4 in the width direction. In the case of B and C, portions 4a and 4 located on both sides of the opening 5 in the upper surface net 4
b may be formed of mesh materials having different mesh sizes and shapes from each other, as typically illustrated in FIG.
FIG. 2D shows an example in which the opening 5 is formed at a position near one end in the length direction of the upper surface net 4, and FIG.
Are formed at one corner of the upper surface net 4. In addition, the bone frame 6 around the upper surface net 4 is not always necessary,
The net material may be directly connected to the bone frames at the upper ends of the side nets 3a and 3b.

As described above, the position, size and shape of the opening 5 are not particularly limited, but are formed such that when the futon baskets 1 are vertically stacked, they are completely covered and hidden by the upper futon baskets 1. It is desirable to do.

The futon basket 1 having the above structure is filled with a filler 9 such as earth and sand or gravels, and a plurality of the futon baskets 1 are stacked in steps as shown in FIG. 3 or as shown in FIG. The retaining wall is constructed by stacking vertically or using both stacking methods. In this case, the upper and lower futon baskets are connected appropriately. In addition, a required number of the futon baskets 1 are arranged side by side in the left-right direction and, if necessary, in the front-rear direction, and they are naturally connected to each other.

When stacking the futon basket 1 as described above, if it is necessary to drive a pile 7 for connecting the upper and lower futon baskets 1, the opening 5 of the upper and lower futon baskets 1, 1 is required. , 5 at the position where they overlap each other, so that only one bottom net 2 of the upper futon basket 1 needs to penetrate the pile 7. For this reason, it is very easy to drive the pile 7 and it can be driven vertically.

In addition to the presence or absence of the pile 7, when the upper futon basket 1 is set on the stone-filled lower futon basket 1, the position of the stuffing stone in the lower futon basket 1 is set. In the case where it is necessary to shift the position to improve the settlement or to replenish a new stone, the work can be performed simply and reliably through the opening 5 of the upper surface net 4.

By stacking the futon basket 1, the opening 5 is completely covered by the upper futon basket 1, so that the filling does not flow out through the opening 5. In addition, since the upper futon basket is always stacked on the upper net of the lower futon basket, the filling 9 in the lower futon basket moves or sinks, so that the upper and lower futon baskets are moved. Even if a gap is formed between the baskets, the upper futon basket does not fall into the lower futon basket due to the support force of the upper surface net 4 and does not incline, so that the stacking state is stable and the stacking strength increases.

The uppermost futon basket 1 may have its opening 5 closed by a suitable means, for example, a lid 8 made of the same net material as the top net 4, but it is used as a space for tree planting such as planting trees. You can also. Alternatively, an ordinary futon basket having no opening 5 may be used for only the uppermost stage.

The futon basket 1 of the above embodiment is provided with four front and rear and left and right side nets 3a and 3b. Either one of the front and rear side nets 3a, 3a or the left and right side nets 3 to prevent the nets from overlapping and save material.
Either one of b and 3b may be omitted, or one of the front and rear and left and right side nets may be omitted.

In the illustrated example, the front and rear side nets 3 are used.
Although a and 3a are short and the left and right side nets 3b and 3b are long, the relationship between the lengths may be reversed. Furthermore, in order to prevent the outflow when filling with a fine particle such as earth and sand, a fine outflow prevention sheet made of a synthetic resin net or the like is provided along at least the inner surface of the front side net 3a. It can also be arranged.

[0023]

As described above, in the futon basket of the present invention, the opening from which the net material is removed is partially formed in a part of the upper netting which overlaps with the upper futon basket.
When laying piles so as to penetrate a plurality of futon baskets when constructing a retaining wall, or when adjusting the position of filled stuffing stones, such work can be performed easily and reliably. it can.
