Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a prefabricated gabion used for earth retaining work, etc.

[Prior art] As this type of prefabricated gabion, for example,
- As described in Publication No. 42092, a ring is formed by bending the tips of the filaments at the end of the body gauze made of rhombic wire gauze, and a frame around the lid gauze is formed between adjacent filaments. It is known that the lid mesh is attached by inserting a connecting bone wire into each ring while holding the wire.

Such gabions are installed on developed land such as residential land or sloped land, but when installing them, a predetermined number (for example, several dozen) of gabions are placed exactly within a specified area of a predetermined width (for example, several tens of meters). In many cases, the conventional gabions mentioned above tend to change dimensions due to filling with soil and stones, as described in detail below. There was a problem that it was difficult to install it accurately.

That is, in the conventional prefabricated gabion, as shown in FIG. 6A, the filaments 1, 1 constituting the body net are twisted one or more times at the intersection 2 at the end of the body net. , the portions of the filaments 1, 1 beyond the intersection portion 2 are inclined portions 1a, 1a which are inclined in a shape of spreading towards the end, and the rings 3, 3 are formed at the tips of the inclined portions 1a, 1a, and the rings 3, 3 are formed at the tips of the inclined portions 1a, 1a. A connecting bone line 4 was inserted into the rings 3, 3, and a frame line 5 of the lid mesh was inserted between the two filaments 1, 1 at the intersection 2. Therefore, when the force from the filled earth and stones acts on the frame line 5 outward (in the direction of arrow a), the slopes 1a, 1a of the filaments 1, 1 are pressed in the direction of arrow b by this frame line 5. As shown by the chain line, the rings 3 and 3 at the tips may be deformed in the direction approaching each other, and the force due to the frame line 5 may cause the connecting bone line 4 to deform.
By acting on the connecting bone line 4, the inclined parts 1a, 1a of the filaments 1, 1 are strongly pulled in the direction of the arrow c, so that the inclined parts 1a, 1a are similarly deformed, and as a result, , the distance L from the intersection 2 to the connecting bone line 4 increases, and the dimensions of the gabion increase accordingly. Therefore, when several dozen gabions are installed in succession, the change in overall dimensions becomes extremely large, making it difficult to precisely install a predetermined number of gabions in a predetermined area. becomes.

This point is the same even when the frame line 5 is inserted between the inclined parts 1a, 1a of the filaments 1, 1 at a position away from the intersection part 2, as shown in FIG. 6B.

[Problems to be solved by the invention] An object of the invention is to provide a gabion that does not undergo dimensional changes even when filled with earth and stones.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the prefabricated gabion of the present invention has a body net made of a diamond-shaped wire mesh and a cover net that is detachable from the body net. A ring is formed by bending the tip of the filament at the end, and the lid mesh is connected by inserting a connecting bone wire for attaching the lid mesh into the ring, in which the wire in the trunk mesh is It is characterized in that the portion beyond the point where the end of the strip intersects with the adjacent filament is a connecting portion that is substantially parallel to the axis of the body mesh, and the ring is formed at the tip of the connecting portion.

[Function] Since the connection part beyond the intersection of the end of the filament with the adjacent filament in the shell net is formed almost parallel to the axis of the shell net, the force from the filled earth and stones etc. will not affect the lid net. Even if the connecting bone line acts on the connecting bone line and the connecting part of the filament is strongly pulled by the connecting bone line, the rings at the ends of the connecting parts of adjacent filaments will approach each other. There is no deformation in the direction, therefore,
No dimensional changes occur in the gabion.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

The gabion 10 shown in FIGS. 1 and 2 includes a gabion 11 having a rectangular cylindrical shape, a cover net 12 attached to the front and rear surfaces of the gabion 11, and the gabion 11 and the cover net 12. It is composed of a connecting bone line 13 that connects.

The shell netting 11 is made up of a bottom portion 11a, left and right side portions 11b, 11b, and a top portion 11c, and these are made of a diamond-shaped wire netting having flexibility to the extent that it can be easily deformed according to the unevenness of the ground. The four surface portions 11a to 11 of the body net 11
Bone wires 14 are inserted into the ridges that are the boundaries of c, as necessary, and wires 14 are inserted into the front and rear ends of the trunk mesh 11 by bending both ends of the filaments 16 constituting the diamond-shaped wire mesh. A ring 17 is formed. In forming this ring 17, as shown in detail in FIG.
The connecting portion 16a beyond the intersection 18 with the adjacent filament 16 at the end is folded back or twisted in a V shape so that the adjacent filaments 16, 16 engage with each other at the intersection 18. without doing anything,
The axis 1 of the body net 11 is simply held in the crossed state.
9 in a direction substantially parallel to the connecting portion 16.
The above-mentioned rings 17, 17 are formed at the tips of a, 16a.

This body mesh 11 can be formed by bending a piece of diamond-shaped wire mesh into a predetermined shape.
It is also possible to form each of the surface parts 11a to 11c by independent diamond-shaped wire meshes and connect them to each other.

Further, the lid net 12 has a rectangular frame line 21.
The frame line 21 is inserted between the parallel connection parts 16a, 16a of the adjacent filaments 16, 16 in the body net 11, and in this state, each side of the body net 11 is The bone line 1 is connected to the ring 17 at the end of the line.
3 and by connecting these connecting bone wires 13 to each other, it is detachably attached to the end of the body net 11. In this case, independent connecting bone lines 13 are used for each side of the trunk mesh 11, but it goes without saying that a single connecting bone line may be used.

In the gabion 10 configured in this way, the connecting portions 16a, 16a at the ends of the filaments 16, 16 in the body net 11 are approximately parallel to the axis 19 of the body net, so that
The force of the earth and stones filled in the gabion 10 is applied to the cover net 12.
The force acts outward on the connecting bone line 13 through the frame line 21, thereby causing the connecting portion 16 to
Even if a, 16a are strongly pulled outward, the connecting portions 16, 16a of the adjacent filaments 16, 16 will not deform in the direction in which the rings 17, 17 at their ends approach each other. Therefore, striae 16,
Distance L from the intersection 18 of 16 to the connecting bone line 13
Since the gabions 10 do not change, the dimensions of the gabions 10 do not change, and a large number of gabions 10 can be reliably connected to a predetermined length.

In the embodiment shown in FIGS. 4 and 5, instead of attaching a frame line around the lid net 12, a frame line is attached to the end of the wire mesh wire 25 constituting the lid net 12, similar to the case of the body net 11. A ring 26 is formed, and the rings 17 and 26 formed on the corresponding sides of the lid mesh 12 and the body mesh 11 are positioned concentrically, and the common connecting bone line 13 is inserted through these rings 17 and 26. By doing so, the lid net 12 and body net 11 are connected.

In this embodiment as well, the force caused by the earth and stones acts outward on the connecting bone line 13 through the lid net 12, and the connecting portion 16a of the filaments 16, 16 in the trunk net 11,
Even if 16a is pulled strongly outward, these connecting parts 16a, 16a will not hold the ring 1 at the tip.
7 and 17 do not deform in the direction toward each other, and therefore, no dimensional change of the gabion 10 occurs.

In each of the above embodiments, a case has been described in which the lid nets 12 before and after the body net 11 are both made of diamond-shaped wire meshes, but they may also be made of welded wire meshes, expanded metal wire meshes, crimp wire meshes, etc. Alternatively, the front and rear lid nets may be constructed of different types of wire nets. Further, the shape of the gabion 10 is not limited to the rectangular shape shown in the embodiment, but may be, for example, a trapezoid shape with an inclined front surface, a parallelogram shape with inclined front and rear surfaces, or a cylindrical shape. A gabion can also be constructed in the same way.

[Effects of the invention] As described above, according to the invention, the connecting portion beyond the intersection of the end of the filament with the adjacent filament in the body net is formed approximately parallel to the axis of the body net. Even if the force from the filled earth and stones acts on the connecting bone line through the lid mesh, and the connecting part of the filament is strongly pulled by the connecting bone line, the connecting part of the adjacent filament is The rings at the ends do not deform in the direction toward each other, thereby reliably preventing dimensional changes of the gabion.
