Description

  The present invention relates to a gabion continuous body formed by arranging a plurality of rectangular gabions made of rhombus metal mesh side by side on the installation site in a state filled with a stone.

  Square gabions used for revetment work, slope work, etc. are formed in a rectangular parallelepiped shape with a rhombus wire netting and filled with stones such as chestnuts and crushed stone, and the installation site of shores and slopes, etc. In addition, they are installed in a state where they are arranged side by side or stacked vertically, thereby forming a reinforcing wall such as a revetment wall or a slope wall. At this time, if the shore or slope is curved, the gabions must be arranged in a curved shape along the topography.

However, since the gabion has a rectangular parallelepiped shape, if the gabions are arranged along a curved landform, a gap having a triangular shape in plan view is formed between adjacent gabions. When the topography is curved in a convex shape, the gap is widened forward, and when it is curved in a concave shape, the gap is widened backward.
If such a gap is formed between adjacent gabions, not only will the finished reinforcing wall look worse, but also the earth and sand on the wall located behind the gabions (the backside earth) will likely flow out through this gap. The outflow of the backside earth and sand causes problems such as collapse of the wall surface and displacement of the gabion.

  Such a problem may also occur when the gabions are installed linearly along a straight terrain. That is, in recent years, in order to speed up the construction, as disclosed in Patent Document 1, the work of filling the gabion with stone is performed at a place different from the installation site, and the stone-padded gabion is installed at the installation site. It is designed to be transported and installed. At that time, the stone-padded gabion is lifted by a lifting device (lifter means), and is carried on a vehicle such as a truck to the installation site. The gabion may be deformed by movement of an internal stone while it is being lifted or lowered by the lifting device, and may not be a complete rectangular parallelepiped. Since the deformed gabion is difficult to be installed without a gap with the side surfaces abutting each other, a gap is easily formed between adjacent gabions, and it is necessary to take some measures against it.

  The technical problem of the present invention is that, in a gabion assembly in which a plurality of gabions are arranged side by side, a simple clogging treatment is applied to a gap formed between adjacent gabions, so that the backside earth and sand through the gap The purpose is to prevent the outflow and at the same time prevent the appearance from deteriorating.

In order to solve the above-mentioned problems, according to the present invention, a plurality of rectangular gabions made of rhombus metal mesh are arranged side by side in a state filled with stones inside, and formed between the side surfaces of adjacent gabions. Covering at least the front or rear surface of the front, rear, and upper surfaces of the gap with a mesh gap cover having a mesh smaller than that of the rhombus wire mesh forming the gabion, and filling the gabion into the gap A gabion continuous assembly is provided, which is filled with a ballast having a size smaller than that of the stone material and not coming out of the mesh of the gap cover.

  In the present invention, preferably, the gap cover is formed of a rhombus metal mesh, and is arranged in a posture in which column lines forming the rhombus metal mesh are oriented vertically.

In the present invention, the adjacent gabions are connected to each other by a connecting fitting made of wire, the connecting fitting is disposed so as to cross the gap, and one end and the other end of the connecting fitting are adjacent to the adjacent gabion. It is desirable to be locked to one side and the other side.
In this case, the connection fitting may also serve as an attachment fitting for attaching the gap cover by engaging with the gap cover.
Or the said clearance gap cover may be arrange | positioned so that this connection metal fitting may be covered from on the said connection metal fitting.

  According to the gabion assembly of the present invention, at least the front surface or the rear surface of the gap formed between adjacent gabions is covered with the gap cover, and the inside of the gap is filled with ballast, so that the backside earth and sand through the gap Can be prevented by the ballast, and at the same time, the appearance of the reinforcing wall can be prevented from deteriorating due to the exposed gap.

It is a principal part enlarged view of FIG. FIG. 5 is a front view of FIG. 4. It is a principal part enlarged view of FIG. It is a perspective view explaining the structure of a gabion. It is a principal part top view which shows 2nd Embodiment of the gabion continuous connection body which concerns on this invention.

  1 to 3 show a first embodiment of a gabion assembly according to the present invention. This gabion continuous assembly 1A has left and right so that a plurality of square gabion 2 made of rhombus wire mesh are curved in a convex shape along the topography at an installation site curved in a convex shape with a stone 3 filled inside. The adjacent gabions 2 and 2 are connected to each other by the connecting metal fittings 4. The gabion connecting body 1 </ b> A is stacked in a plurality of stages to form a stepped shape. Reinforced walls such as revetment walls and slope walls are formed.

  For the sake of clarity, FIG. 1 is drawn in an enlarged state with respect to FIGS. 2 and 3, and the description of the stone 3 is omitted in FIGS. 2 and 3. Moreover, although the said gabion continuous connection body 1A is stacked in two steps of upper and lower sides, this gabion continuous connection body 1A can be stacked in three steps or more, and can be installed in only one step.

  As shown in FIG. 7, the gabion 2 is arranged on a rectangular bottom mesh 7a, a rectangular front mesh 7b and a rear mesh 7c arranged before and after the bottom mesh 7a, and on the left and right of the bottom mesh 7a. A rectangular parallelepiped gabion formed by connecting a rectangular left mesh 7d and a right mesh 7e, and a rectangular upper mesh 7f, and a longitudinal length a connecting the front mesh 7b and the rear mesh 7c. The left and right long length b connecting the left surface net 7d and the right surface net 7e is formed longer.

  The bottom mesh 7a, the front mesh 7b, the rear mesh 7c, the left mesh 7d, and the right mesh 7e may be individually formed and connected to each other, for example, the bottom mesh 7a, the front mesh 7b, and the rear mesh. When the direction of the column line 9 with respect to 7c is the same as each other, that is, when the direction of the column line 9 is horizontal as shown in the drawing, they can be integrally formed by one rhombus wire mesh.

Adjacent surface meshes are connected by binding the corresponding sides of the outer peripheral frame 10 made of wire surrounding the outer peripheries of the surface meshes by winding a coiled binding metal 11. . Reference numeral 12 in the figure is a reinforcing wire provided at an intermediate position of each surface net.
The rhombus wire mesh is formed by sequentially locking the bent portions 9a of the row lines 9 formed by bending in a flat spiral shape.

  As apparent from FIGS. 3 and 4, the plurality of gabions 2 are arranged side by side along the convex terrain, and therefore, between the side surfaces of the adjacent gabions 2, 2, that is, one gabion. A gap 14 is formed between the right-side net 7e and the left-side net 7d of the other gabion 2 and forms a substantially triangular shape in plan view. When such a gap 14 is formed, not only the appearance of the reinforcing wall, particularly the appearance from the front side, is deteriorated, but the appearance is also impaired, and the earth and sand (the backside earth and sand) of the wall surface 15 located behind the gabion linking body 1A. ) Easily flows out through the gap 14, and the wall surface 15 collapses due to the outflow of the backside earth and sand and the position of the gabion 2 is displaced.

  Therefore, a gap cover 16 is attached between the adjacent gabions 2 and 2 so as to cover the front surface 14 a of the gap 14, and a ballast 17 is filled so as to fill the inside of the gap 14. This ballast 17 prevents the backside earth and sand from flowing out from the wall surface 15 behind the gabion connecting body 1A through the gap 14, and at the same time prevents the position of the adjacent gabions 2 and 2 from being displaced, The gap cover 16 covers the front surface 14a of the gap 14, thereby preventing the gap 14 from being exposed and improving the appearance of the reinforcing wall, and also preventing the ballast 17 from leaking out of the gap 14. Fulfill.

  As is apparent from FIGS. 5 and 6, the gap cover 16 is formed by a rhombus metal mesh that sequentially locks the bent portions 18 a of the row line 18 having a flat spiral shape. The wire diameter is smaller than the wire diameter of the row wire 9 of the rhombus wire mesh that forms the gabion 2, the mesh size is smaller than the mesh of the rhombus wire mesh that forms the gabion 2, and the ballast 17 is pulled out. There is no size. Therefore, as a matter of course, the ballast 17 has a smaller diameter than the stone material 3 filled in the gabion 2.

  In addition, the gap cover 16 is disposed in a posture in which the direction of the row line 18 is vertical so as not to buckle in the vertical direction, and between the adjacent gabions 2 and 2 by the connecting metal fitting 4 made of wire. It is attached. That is, as apparent from FIG. 6, the connecting metal fitting 4 is inserted into the mesh of the rhombus metal mesh forming the gap cover 16 so as to be locked to the row line 18, thereby It is arranged so as to cross the front surface 14a, one end of which is locked to the outer peripheral frame 10 at the end of the front mesh 7b and the right mesh 7e of one gabion 2, and the other end is the front mesh 7b of the other gabion 2. And the outer peripheral frame 10 at the end of the left-side net 7d, whereby the adjacent gabions 2 and 2 are connected to each other by the connecting fitting 4 and at the same time the gap cover 16 is adjacent. Attached between the gabions 2 and 2. Accordingly, the connecting metal fitting 4 has a function of attaching the gap cover 16 in addition to a function of connecting the adjacent gabions 2 and 2 together.

  The wire diameter of the connection fitting 4 is equal to or greater than the wire diameter of the rhomboid wire mesh line 9 forming the gabion 2, and both ends of the connection fitting 4 are locked to the outer peripheral frame 10. Thereafter, the folded ends 4a are folded inward so as to face each other, but it is desirable that the folded end 4a be folded as far as possible inside the gap cover 16 without exposing it to the outside.

  In the example shown in FIG. 5, the three connecting fittings 4 are provided at three positions, that is, the upper end portion, the middle portion, and the lower end portion of the front mesh 7b, but the number of the connecting fittings 4 is four or more. Alternatively, the two connecting metal fittings 4 may be disposed at two locations, the upper end portion and the lower end portion of the front mesh 7b.

  Further, the gap cover 16 is attached to the gabion 2 with the connecting metal fitting 4 or, instead of being attached with the connecting metal fitting 4, using another cover mounting metal made of wire or the like, the adjacent gabion 2, 2 may be connected. In this case, the column line 18 on the left and right end sides and the column line 18 on the other end side of the gap cover 16 are connected to one outer peripheral frame 10 or column line 9 and the other outer peripheral frame 10 or column of the adjacent gabions 2 and 2. The cover 9 is connected to the line 9 by the cover mounting bracket.

  As described above, when the gap cover 16 is attached with another cover attachment bracket, the gap cover 16 is attached so as to cover the connection bracket 4 from above after connecting the adjacent gabions 2 and 2 with the connection bracket 4. By doing so, it is possible to prevent the folded end 4a of the connecting metal fitting 4 from being exposed to the outside and improve safety. Therefore, in this case, the gap cover 16 also has a function as a safety cover.

  The gap cover 16 is not for firmly connecting the adjacent gabions 2 and 2 so as not to be displaced, so that the cover mounting bracket has a wire diameter similar to that of the row line 18. A relatively thin and easy-to-bend wire can be used. Therefore, it is relatively easy to process the end of the cover mounting bracket in a state where the end is bent toward the inside of the gap cover 16 for safety.

  However, since the gap cover 16 has a certain strength and can connect the gabions 2 and 2 with a certain level of strength, the gabions 2 and 2 are installed in a place where a large external force is difficult to act. In this case, the gap cover 16 may be attached to the gabions 2 and 2 with the cover mounting bracket, and the coupling between the gabions 2 and 2 by the coupling bracket 4 may be omitted.

  On the rear surface 14b side of the gap 14, the rear end portions of the left mesh 7d and the right mesh 7e of the adjacent gabions 2 and 2 are close to each other or in contact with each other with a slight gap. Yes, these portions are connected to each other by a connecting fitting 19 made of a wire as necessary. In this case, when the gap on the rear surface 14b side is somewhat large, a gap cover can also be attached to the rear surface 14b. When the gap between the rear surfaces 14b is small or almost absent, the gap cover is omitted. can do.

However, when the rear surface 14b of the gap 14 faces the wall surface 15 and the wall surface 15 serves as a gap cover to prevent leakage of the ballast 17, even when the interval is somewhat large, It may not be necessary to provide the gap cover.
As for the upper surface 14c of the gap 14, a gap cover that covers the upper surface 14c can be attached as needed, or a connecting fitting for connecting the adjacent gabions 2 and 2 can be provided.

  The gap cover 16 is not limited to the rhombus metal mesh, but can be formed of a weld metal mesh, a synthetic resin net, or the like. The welded wire mesh is formed by integrating the intersections of vertical iron wires and horizontal iron wires arranged in a lattice shape by electric resistance welding.

  Further, the gap cover 16 can be colored in a color different from that of the gabion 2, and by coloring the gap cover 16 in this manner, the gap cover 16 is arranged in a pattern, so that the appearance of the revetment wall can be improved. This improves the design effect.

  In the illustrated embodiment, the gap cover 16 is formed to have a width that substantially fits the width of the front surface 14 a of the gap 14, but the width of the gap cover 16 is larger than the width of the gap 14. Thus, both end portions of the gap cover 16 are partially overlapped with the front meshes 7b and 7b of the adjacent gabions 2 and 2, and the overlapping portions are fixed to the front meshes 7b and 7b with the cover mounting brackets. You can also. In that case, it is preferable that the gap overlap between the gap cover 16 and the front mesh 7b is about two from half the mesh of the rhombus metal mesh that forms the front mesh 7b.

If there is a place where the gap 14 is not formed between the adjacent gabions 2 and 2 in the gabion continuous body 1A, the gap cover 16 may be attached between the adjacent gabions 2 and 2 or the ballast 17 need not be filled.
If the width of the gap 14 differs depending on the location, the width of the gap cover 16 may be changed for each gap 14 according to the width of the gap 14. 16 may be attached.

  On the other hand, when the gabion 2 is installed side by side along the concave terrain, the side surfaces of the adjacent gabions 2 and 2 are opposite to the case where the gabion 2 is installed along the convex terrain as described above. In the meantime, a gap having a substantially triangular shape with a plan view shape extending rearward is formed. In this case, a gap cover is attached to at least the rear surface of the gap, and the gap is filled into the gap, and a gap cover is attached to the front and upper surfaces of the gap as needed. The other structure is the same as the case where the gabion 2 is installed along the convex terrain.

FIG. 8 is a plan view of an essential part showing a second embodiment of the gabion assembly according to the present invention. A gabion assembly 1B according to the second embodiment is provided by arranging a plurality of gabions 2 in a straight line on the left and right. It is a thing.
Even when the gabions 2 are installed in a straight line as described above, a gap 14 may be formed between the adjacent gabions 2 and 2. For example, as described in the background art, when the gabion 2 packed in a place other than the installation site is transported to the installation site by a vehicle such as a truck, the gabion 2 is lifted by a lifting device. The gabion 2 may be deformed by the movement of the internal stone material while it is lowered or lowered, and may not be a complete rectangular parallelepiped. If such gabions 2 are installed side by side on the site, the gap 14 may be formed between the adjacent gabions 2 and 2 as shown in the figure.

  In FIG. 8, the gap 14 is drawn in an undistorted rectangle, but in fact, the side surface of the gabion 2 is irregularly deformed, so the shape of the gap 14 is not constant, The gabion 2 changes irregularly in the front-rear direction and the vertical direction (height direction), and the width of the gap 14 also varies irregularly. This is the same for the triangular gap 14 formed between the adjacent gabions 2 and 2 when the gabion 2 previously packed in the gabion linking body 1A of the first embodiment is used.

Also in the gabion assembly 1B of the second embodiment, the gap 14 is filled with the ballast 17, and at least the front surface 14a of the front surface 14a, the rear surface 14b, and the upper surface 14c of the clearance 14 is covered with the clearance. By closing with 16, it is possible to prevent the backside earth and sand behind the gabion linking body 1 </ b> B from flowing out through the gap 14 and improve the appearance of the reinforcing wall.
Other configurations of the gabion continuous structure 1B of the second embodiment are the same as those of the gabion continuous structure 1A of the first embodiment.
