Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gabion connecting body which is preferably used in revetment works, riverbed works and the like, and a construction method thereof.

[0002]

2. Description of the Related Art In general, the gabion construction method is most suitable as an emergency construction method in an emergency, and is widely used for disaster prevention work on rivers because of its excellent flexibility, water permeability and cushioning property.
In recent years, durable gabion has been encouraged in river protection, particularly in first-grade rivers, from the viewpoint of preserving a favorable growth environment for living creatures and natural scenery in riverbank construction and riverbed construction.

In such a gabion method, a cylindrical or square gabion is generally used, and these gabions are sequentially arranged in a predetermined place and connected to each other, and are then filled with stones inside. The gabion that has been made can withstand torrents, and even when ground subsidence due to the flow of earth and sand occurs, the gabion that is adjacent to the gabion changes in accordance with the deformed topography and is well suited to that topography It must be able to fully fulfill its functions such as revetment by becoming familiar and stable, and it can be said that the cylindrical gabion is superior to the square gabion in such functions. In particular, when it is installed on a slope, the tendency becomes remarkable.

[0004] The cylindrical gabion is usually a cylindrical body net made of a rhombus wire net, and a circular ring for shape keeping, which is arranged inside the body net at a required interval to keep the body net in a cylindrical shape. And a lid net that closes both ends of the body net, and when connecting gabions to each other when installing on a slope or the like, connect the wire lines of the wire net in the body net with wire, The method of connecting the circular rings through the mesh was used, but when the row lines are connected at a fixed position, the freedom between adjacent gabions is reduced and the movement is restricted, resulting in ground subsidence. However, there is a drawback in that it cannot be fully displaced following the conditions such as being in an unstable state, and its original function can not be fully exhibited. Even if it is movably attached to the ring, it will move along the ring. Since the range that can be the only internal mesh diamond wire mesh, to the extent that some degree of freedom is increased than the case of connecting the column lines to each other, it can not be sufficiently displaced to follow the fluctuations of the ground.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a plurality of gabions with a large degree of freedom so that they can be installed in a mutually connected state so that they can be displaced sufficiently in response to changes in the ground. To configure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described in detail with reference to the drawings. In the gabion-connecting body shown in FIGS. 1 and 2, a plurality of gabions 1 are sequentially arranged along a slope such as a riverbank. In addition, these gabions 1 are connected to each other, and the gabions 1 are installed by filling the inside of each gabion 1.

As is apparent from FIG. 3, the gabion 1 is formed into a ring shape by a cylindrical body net 2 made of a rhombus wire net and a wire, and is arranged inside the body net 2 at a predetermined interval. By this, a round ring 3 for shape keeping that keeps the body net 2 cylindrical,
It is composed of a cover net 4 that closes both ends of the body net 2, and a connecting ring 5 formed in an annular shape by a wire is wound around and adjacent to a required position on the outer periphery of the body net 2. Gabion 1,1
The circular lines 5 and 5 are connected to each other by a connecting member 6 which is movable along the circular lines 5 and 5.

The ring wire 5 is formed so as to have a shape and size substantially the same as the shape-retaining round wheel 3 and is attached to an appropriate position of the trunk net 2 at an appropriate interval, but preferably, As shown in the figure, it is to be installed at a position close to both ends of the body net 2 and an intermediate part with a space of 2 to 4 m.
In this case, it is desirable to arrange the round wheels 3 close to each other on both sides of each wheel line 5, and in particular, as shown in detail in FIG. 4, the two round wheels 3 and 3 are spaced by one mesh. It is desirable to dispose the wire 5 in the entangled portion 7a of the wire 7 of the wire mesh, and to dispose the wire 5 in the middle of these round wheels 3,3. Can be installed stably.
In addition, when the annular frame lines 8 are attached to both ends of the trunk net 2, these frame lines 8 can be used as a substitute for the ring 3. The ring wire 5 may be formed of the same material as the round wheel 3, but it is preferable that the ring wire 5 is formed of a material having a higher strength than the round wheel 3 because a large connecting strength is required.

Further, the connecting member 6 for connecting the above-mentioned wheel lines 5 and 5 can be made of any material such as wire, and the structure thereof is also movable along both the wheel lines 5 and 5. Any kind of wire may be used, for example, even if the wire is directly wound on both the ring wires 5,5,
Alternatively, rings that are movably attached to each other may be connected to each other by appropriate members.

In the installation site, the gabion connecting body having the above-mentioned structure holds the body gauze 2 in a cylindrical shape by inserting the round ring 3 into a predetermined position within the body gauze 2 of the gabion 1, and After attaching the lid nets 4 to both ends of the wire 2 and winding the connecting wheel 5 around the outer circumference of the body net 2 at predetermined positions, each gabion 1
Are arranged side by side in close proximity to each other, and the wheel lines 5 and 5 of the adjacent gabions 1 and 1 are mutually connected by the connection member 6 so that the connection member 6 can move along the wheel lines 5 and 5. Connect to. Then, after stuffing stones from the stuffing stone hole provided in the trunk net 2, the stuffing stone hole is closed to install.

As shown in FIG. 5, the gabion 1 thus installed is integrated with each other by connecting the wheel lines 5 and 5 to each other and is stably positioned on the ground 9.
As shown in FIG. 6, when a part of the ground 9 subsides,
The gabion 1 located at that portion is deformed or displaced in accordance with the subsidence of the ground 9, and is well adapted to the terrain and kept stable. At this time, between the adjacent gabions 1 and 1, the connecting member 6 connecting the wheels 5 and 5 can freely move along the wheels 5 and 5, and the displacement amount of the gabion 1 can be increased. Since the connecting position is changed in accordance with the above, the movement of the gabion 1 is not excessively restricted by the adjoining gabion via the connecting member 6, and each gabion 1 is surely displaced according to the shape of the ground 9. be able to.

[0014]

As described above, according to the present invention, the connecting wheel is wound around the outer circumference of the body net in the gabion, and the wheel lines of the adjacent gabions are connected by the connecting member movable along the wheel. Since they are connected to each other, each gabion can be connected to each other with a large degree of freedom so that it can be sufficiently displaced in accordance with changes in the ground. As a result, if ground subsidence occurs However, it can be stabilized by transforming the gabion into a state that is well adapted to the terrain.
