Abstract

PROBLEM TO BE SOLVED: To improve connecting strength by arranging a plural number of vertical cylindrical stone packed cages extended by crossing brace wires for reinforcement on at least a cover net close to each other at a position of the brace wires and connecting adjacent brace wires to each other. SOLUTION: A stone packed cage 2 is constituted by radially providing a plural number of brace wires 4 for reinforcement passing through a center of a cover net and a bottom net to surround a vertical cylindrical cage main body. In case of laying the cage 2 on a river bed, etc., the adjacent cages 2 are made contact with each other at a position of the brace wires 4, and the brace wires 4 of the adjacent cages 2 are connected to each other at a connecting point 5. At this time, as the brace wires 4 as an overall structural body are connected to each other in a straight line, connecting force of the cages 2 with each other becomes extremely large. Consequently, it is possible to certainly support external force of a water current, etc., in the positionally slipping direction working on the stone packed cage, to prevent deformation of a connecting part of the stone packed cage and breaking of connection between the stone packed cages, and as the river bed makes contact with flowing water and atmospheric air through a proper clearance formed between the stone packed cages, it is possible to form natural and favourable ecological environment.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure made of a plurality of vertically packed cylindrical stone baskets connected to each other.

[0002]

2. Description of the Related Art For example, a rectangular square gabion (futonkago) is generally used as a stone stuffing basket laid on the bottom of a river or a seawall. Such a square gabion,
They are laid on the riverbed or riverbank by arranging them vertically and horizontally, or by stacking them up and down, to reduce the flow velocity of the water flow to suppress the flow of stone and sand, and to protect the riverbank from the water flow. However, when such a square gabion is laid tightly on the riverbed, almost no gaps are formed between adjacent stone baskets, so that the original riverbed is completely covered with the stone basket and running water, air, etc. From the natural environment, resulting in an unnatural ecological environment. On the other hand, a round gabion having a short cylindrical shape (Dharmago) has been conventionally known, and when such a round gabion is used, a gap is formed between adjacent gabions, and the above-described disadvantages of the square gabion. However, there is a problem that the bonding force between the gabions is weak by the amount of the gap, and the position is easily displaced or deformed when an external force due to a water flow or the like acts. If adjacent gabions are connected to each other, the bonding force between each gabion will increase, but simply connecting parts of the gabion to each other will cause external force to act locally on those connections through the adjacent gabion. Therefore, the gabion is easily deformed at the connecting portion.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to increase the connection strength between stone baskets in a structure formed by connecting a plurality of short cylindrical stone baskets.

[0004]

According to the present invention, there is provided, according to the present invention, a short cylindrical trunk net, a lid net closing an upper surface of the trunk net, and a bottom net closing a bottom surface of the trunk net. A vertical cylindrical basket body consisting of at least the lid net, a plurality of stone cages stretched so that a plurality of reinforcing bracing lines cross each other, the position of the bracing lines The stone-made basket structure is provided so as to be adjacent to the adjacent stone-filled basket and to connect the line of intersection of the adjacent stone-filled basket with each other.

[0005] In the structure having the above-described structure, since the crossing lines are connected to each other between adjacent stone baskets, the crossing lines are connected to one as a whole structure. The supporting force by the crossing line becomes very large.
Therefore, the bonding force between the stone baskets is also very large, and even if external forces in the direction of displacement are applied to some stone baskets due to water flow or the like, the external forces are surely supported by the support force of the above-mentioned line of intersection. Thus, the stone basket is not locally deformed at the connection portion and the connection between the stones is not broken. In addition, even if the cylindrical stone baskets are densely arranged, an appropriate gap is always formed between adjacent stone baskets, and a conventional riverbed can come into contact with flowing water or the atmosphere through this gap. , A natural and good ecological environment can be obtained.

According to one specific embodiment of the present invention, the stone stuffing baskets are two-dimensionally arranged, and a plurality of connecting lines in which the crossing lines of adjacent stone stuffing baskets are mutually connected. Adjacent ones of the points are interconnected by support lines. As a result, the force acting on one connection point is dispersed and supported at the plurality of connection points by the support line, so that excessive force does not act intensively on only one connection point, and Not only can the supporting force of the wire be used more effectively, but also the connected state of each stone basket becomes more stable. According to another specific configuration aspect of the present invention, the stone stuffing baskets are arranged two-dimensionally, and in a gap formed between a plurality of stone stuffing baskets, each stone stuffing basket is substantially provided. , A small columnar member is interposed so as to be close to. In this case, among the plurality of connection points connecting the bracing lines of the adjacent stone baskets to each other, the adjacent ones can be connected to each other by the support line. According to another specific embodiment of the present invention,
A three-dimensional structure is formed by stacking a plurality of stacked stone baskets having the same configuration as the above structure vertically.
The stone-filled basket forming the structure of the present invention may have a configuration in which a reinforcing frame is wound around the outer periphery of the cylindrical body of the basket body in the circumferential direction.

[0007]

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 a first embodiment of a structure according to the present invention.
Is arranged in a two-dimensionally dense manner in a plurality of vertically packed stone-filled baskets 2 to form a mat.

As shown in FIG. 3, the stone basket 2 is composed of a cylindrical trunk net 3a made of a diamond-shaped wire mesh, a lid net 3b for closing the upper surface of the trunk net 3a, and a bottom net 3c for closing the bottom surface. A plurality of reinforcing bracing lines 4 surrounding the cage body 3 are arranged radially across the center of the lid net 3b and the bottom net 3c in the vertical cylindrical basket body 3. It has a flat cylindrical shape with a height lower than the diameter. The crossing line 4 is formed by the center C of the lid net 3b and the bottom net 3c where they intersect.
May be combined into one.

At the upper and lower ends of the trunk network 3a,
It is desirable to form a tube at the end of each of the row lines constituting a, and to form a circular edge frame by inserting a wire through the tube. Similarly, the lid net 3b and the bottom net 3c It is desirable to attach an edge frame also to the outer periphery of. This allows
The trunk net 3a, the lid net 3b, and the bottom net 3c can be easily and reliably connected using the above-mentioned edge frame.

It is preferable that a series of the crossing lines 4 are arranged along the inner surface or the outer surface of the basket main body 3 and fixed at some places to a row line, an edge frame or the like. Net 3a
And the mesh of the lid net 3b and the bottom net 3c. Alternatively, instead of extending a series of cross lines, individual cross lines are formed on the trunk net 3a, the lid net 3b, and the bottom net 3c, and these nets 3a, 3b, 3c are packed with stones. When assembled as a basket, the corresponding crossing lines may be connected to one another. The crossing line 4 and the edge frame are connected to the trunk net 3a, the lid net 3b, and the bottom net 3
The line may be formed using the same line as the line of the rhombic wire netting constituting c, but it is desirable to form the line having a strength higher than that of the line.

As can be seen from FIG. 2, the above-mentioned stone basket 2 is formed by shifting the positions of the front stone basket 2 and the rear stone basket 2 by a radius in the row direction (lateral direction). The rear row of stone baskets 2 is positioned between adjacent ones of the front row stone baskets 2, and the adjacent stone baskets 2 are closely contacted with each other at the position of the crossing line 4. The connecting lines 4, 4 of the adjacent stone baskets 2, 2 are connected to each other at a connection point 5 by a connection fitting such as a wire or a clip. Therefore, in the illustrated example, each stone basket 2 has three crossing lines 4
Are attached at intervals of 60 degrees. Each of the above stone baskets 2
Needless to say, the inside is filled with stones.

The position at which the crossing lines 4 of the adjacent stone baskets 2 are connected to each other is preferably at the upper and lower corners of the stone basket 2.
The connection may be made at one or more positions in the middle part of the trunk network 3a, or may be made at both the upper and lower ends and the middle part. When connecting the crossing lines 4, only the crossing lines 4 may be connected, or they may be connected together with an edge frame or a column line.

[0013] The structure having the above structure, for example, when it is installed on a riverbed, exhibits functions such as a reduction in flow velocity due to diversion and prevention of debris flow. In this case, since the adjacent stone baskets 2 and 2 are arranged so as to be in contact with each other at the position of the line of intersection 4, the line of intersection 4 of each stone basket 2 and 2 are connected to each other. In addition, the line of intersection 4 is arranged in a straight line as a whole of the structure, and the supporting force by the line of intersection 4 is very large. Therefore, the bonding force between the individual stone baskets 2 becomes very large, and even if an external force in the direction of displacement is applied to some of the stone baskets 2 due to a water flow or the like, the external force is increased by the support force of the cross line 4. It is securely supported, and the stone basket 2 is not locally deformed at the connection portion, and the connection between the stone baskets 2 is not broken.

[0014] Further, when the rectangular stone baskets are closely packed, almost no gap is formed between the adjacent stone baskets, so that the original riverbed is completely covered with the stone baskets and the running water is filled. Although it was inevitable to become an unnatural ecological environment because of being shielded from the sea and the atmosphere, etc., in the structure composed of the cylindrical stone stuffing baskets 2, the stone stuffing baskets 2 are densely arranged and braced. Even if the line 4 is firmly connected, an appropriate gap is always formed between the adjacent stone baskets 2. Through this gap, the native riverbed can come into contact with flowing water and the atmosphere, so that natural and good ecological Environment can be obtained.

FIG. 4 shows a second embodiment of the present invention.
In the structure 1B of the second embodiment, among the plurality of connection points 5 connecting the crossing lines 4 of the adjacent stone baskets 2 to each other, the adjacent connection points 5, 5 are mutually connected by the support line 6. It is connected to. As a result, the force acting on one connection point 5 is dispersed and supported by the plurality of connection points 5 by the support line 6, so that an excessive force acts intensively on only one connection point 5. In addition, not only can the support force of the crossing line 4 be used more effectively, but also the connection state of the stone baskets 2 can be further stabilized.

FIG. 5 shows a third embodiment of the present invention.
The structure 1C of the third embodiment has a small columnar member 9 interposed in a gap 8 formed between adjacent stone stuffing baskets 2 so as to substantially contact each of the stone stuffing baskets 2. is there. Stone basket 2
By interposing such a small columnar member 9 in the gap 8 between them, it is ensured that each stone basket 2 swells toward the gap 8 and is deformed or displaced in the direction of the gap 8. Can be prevented. The small cylindrical member 9 may be a small-diameter stone basket or a hollow or solid pile, and when a pile is used, the installation state of the structure can be more stabilized. it can. In the third embodiment, FIG.
As shown in the second embodiment shown in FIG.
Of course, adjacent ones may be connected to each other by a support line.

FIG. 6 shows a fourth embodiment of the present invention.
The structure 1D of the fourth embodiment is different from that of the first embodiment in that the stone basket 2 in the front row and the stone basket 2 in the rear row are arranged at the same position in the front and rear. Therefore, in the fourth embodiment, two crossing lines 4 are attached to each stone basket 2 at intervals of 90 degrees. However, the stone basket 2 used in the fourth embodiment may be one in which four crossing lines are attached at intervals of 45 degrees. Also, in the fourth embodiment, adjacent portions of the plurality of connection points 5 of the cross-section line 4 can be connected to each other by the support lines 6, as indicated by a part of a chain line. Needless to say.

FIG. 7 shows a fifth embodiment of the present invention.
The structure 1E according to the fifth embodiment is a small-diameter auxiliary stone as a small columnar member in a gap portion 8 formed between four adjacent stone stuffing baskets 2 so as to substantially contact each of the stone stuffing baskets 2. At the same time, the intersecting lines 4 of the adjacent stone packing baskets 2 are connected to each other with the intersecting baskets 10 interposed therebetween. It is connected to.
In this case, it goes without saying that a pile can be used instead of the auxiliary stone basket 10. In addition, as shown by a chain line, adjacent ones of the plurality of connection points 5 of the cross line 4 in each stone basket 2 can be connected to each other with the support line 6. This is the same as the embodiment.

In the structures of the first to fifth embodiments, the stone stuffing baskets 2 are arranged in one level in a plane, but a three-dimensional structure is formed by stacking a plurality of levels vertically. You can also. The sixth embodiment shown in FIGS. 8 and 9 shows an example of such a three-dimensional structure, and this structure 1F has a plurality of stone-filled baskets 2 arranged two-dimensionally and connected. By doing so, the first
In this embodiment, the stone-meshed linked bodies 14 configured as any one of the planar structures 1A to 1E of the fifth to fifth embodiments are stacked in a plurality of stages vertically and installed on a bank of a river. In this case, in the illustrated embodiment, the front surface of the structural body 1F is inclined by sequentially shifting the upper-stage stone basket connecting members 14 backward, but it is not always necessary to shift the upper-stage one. In addition, although the upper-stage stone basket connecting members 14 are sequentially stacked in a state shifted laterally by the radius of the stone basket 2 from the lower stage, it is not always necessary to shift, and the stacking is performed at the same position. You can also.

The structure of each of the above embodiments is a stone basket 2
Are two-dimensionally arranged in front and rear and left and right and connected, but may be one-dimensionally arranged and connected in only one of the vertical and horizontal rows. In this case, only one cross line 4 is connected linearly in the direction of the row.

FIG. 10 shows a different example of the construction of the stone basket which constitutes the structure of each embodiment described above.
Is higher than that shown in FIG. 3 and has a cylindrical body 3a.
A reinforcing frame 15 is wound around the outer periphery of the body. In this case, the frame 15 may be connected to each of the cross lines 4 at their intersections. As described above, depending on the installation location and installation purpose of the structure, a tall stone basket is used, and the height is usually smaller than the diameter of the cylinder, but in some cases, the height is formed equal to or larger than the diameter. Sometimes. When the height of the stone basket is high as described above, one or more of the above-described frame lines 15 may be attached at appropriate positions in order to reinforce the trunk net 3a and prevent its deformation. desirable.

In each of the above embodiments, the cross lines 4 are extended from the lid net 3b to the trunk net 3a and the bottom net 3c on the stone baskets 2 and 2A. 3b, or may be extended to the lid net 3b and the trunk net 3a except for the bottom net 3c. In the case of being stretched between the lid net 3b and the trunk net 3a, the respective crossing lines 4 may be a series extending over both nets 3a and 3b or may be independent for each net. good. In short, it is only necessary to stretch in such a manner that the line of intersection of the adjacent stone baskets can be connected to one.

The plurality of crossing lines do not necessarily have to pass through the center of the lid net 3b or the bottom net 3c.
Although they cannot be connected to each other at one point at the center of the lid net 3b or the bottom net 3c, it is desirable to connect the crossing lines at the intersections.

Further, in each of the above embodiments, the adjacent stone baskets are brought into contact with each other, but they are not completely brought into contact with each other, so that water can flow without resistance. It can be installed with a small gap that allows it to pass freely.

Although the stone basket 2 of each of the above embodiments is formed of a diamond-shaped wire netting, it may be made of other net-like materials, for example, a welded wire net or a hard synthetic resin net. In addition, the case where the structure is installed on the riverbed or seawall of a river has been described. However, it is needless to say that the structure can also be used for earth retaining work on a laid land or a sloping land.

[0026]

According to the structure of the present invention, by connecting the crossing lines between adjacent stone baskets, the above crossing lines are connected as one as a whole structure. Therefore, the supporting force by the line of intersection becomes very large, and the bonding force between the stone baskets becomes very large. As a result, even if an external force in the displacement direction is applied to some of the stone baskets due to water flow or the like, the external force is reliably supported by the support force of the cross line, and the stone baskets are locally connected at the connecting portion. Deformed,
The connection between them is not broken. In addition, even if the cylindrical stone baskets are densely arranged, an appropriate gap is always formed between adjacent stone baskets, and a conventional riverbed can come into contact with flowing water or the atmosphere through this gap. , A natural and good ecological environment can be obtained.
