Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing gabions on slopes, embankments, etc.

When constructing a gabion, a method of filling stones using mechanical power such as a power shovel or a bulldozer has traditionally been used to improve work efficiency and speed up the work. In order to pack stones uniformly and in a stable state, this machine applies impact force or pressing force from above after the filling is completed, but at this time the gabion may move and shift its position. It is easy to bulge and deform.

In order to solve such problems, conventionally, as described in Japanese Patent Publication No. 51-43695, long frame plates that span these gabion bodies are connected to the sides of a large number of gabion bodies, and each A method of removing the frame plate after filling the gabion body with stones has been used, but although the deformation prevention effect of the frame plate can be considerably enhanced, it still has the following problems.

a) It requires a long frame plate that spans multiple gabion bodies, making transportation and handling inconvenient.

b. Places where gabions are installed are not necessarily flat, but are often uneven or sloped.
Each gabion may also shift vertically accordingly, and therefore, it is difficult to attach a long frame plate to span a large number of gabions in such a location.

c When filling with stones, because the side pieces in contact with the adjacent gabion body are not reinforced, the side pieces are likely to be crushed downward by the load of the stones or the pressing force from the machine, or bulge and deform toward the adjacent gabion body. Once such a bulge occurs, it becomes difficult to subsequently fill adjacent gabions with stones, and the shapes and sizes of each gabion tend to become unbalanced.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and it is an object of the present invention to provide a method for installing gabions that can be installed continuously without deforming the gabions using a simple method. be.

In order to achieve the above-mentioned object, the present invention provides a surrounding frame around the four circumferences of a gabion main body that is placed in a predetermined installation location, and removes the surrounding frame after filling the gabion main body with stones. This is its characteristic.

Hereinafter, embodiments of the present invention will be described based on the drawings. In FIG. 1, a rectangular box-shaped gabion main body 1 is formed of, for example, a diamond-shaped wire mesh. 3 and front and rear side pieces 4, 4 are attached.When filling the inside of this gabion body 1 with stones, the gabion body is left empty with the lid (not shown) removed and placed in a designated facility. A surrounding frame 6 is erected around the gabion main body 1 to surround its four sides. This surrounding frame 6 is made of iron,
It consists of left and right frame plates 7, 7 made of aluminum alloy or the like in a thin plate shape, and front and rear frame bodies 8, 8. connected to. Here, the frame plates 7, 7
The connection between the frame plates 8, 8 and the frame plates 8, 8 can be performed by any means, for example, the first
As shown in the figure, window holes 9, 9 formed in the frame plate 7
Insert the rings 10, 10 attached to the frame plate 8 into the
This can be done by inserting both ends of a U-shaped locking pin 11 into the rings 10, 10. In this case, it is desirable to enclose the surrounding frame 6 in close contact with the side pieces of the gabion main body 1 as much as possible, and if it is assembled by the method shown in the figure, after filling with stones, In order to facilitate disassembly and removal, the window hole 9 formed in the frame plate 7 is preferably formed vertically.

After thus enclosing the surrounding frame 6 around the gabion main body 1,
Stones are packed into the gabion main body 1 using a machine such as a power shovel or a bulldozer, and pressure is applied from above using these machines so that the packed stones are in a uniform and stable state. In this case, the side pieces 3, 3 of the gabion body 1
and 4, 4 are reinforced by surrounding them with the enclosing frame 6, so that there will be no inconveniences such as these side pieces being crushed or bulging outward, making it efficient and the overall structure Therefore, the filling stones are extremely stable within the gabion main body 1, and the quality of the gabion is improved.

When the filling of stones into the gabion main body 1 is completed as described above, the locking pin 11 is removed from the ring 10, the surrounding frame 6 is disassembled, and each frame plate 7, 8 is removed. Then, by attaching a top cover to the top surface of the gabion main body 1, the installation is completed. Incidentally, the upper cover may be attached before removing the enclosing frame 6, and may not necessarily be attached depending on the facility location and situation of the gabion.

By repeating the above-mentioned operations, gabions can be installed over a desired distance.

Therefore, in this method, new gabions are constructed one after another adjacent to the gabions 5 that have already been filled with stones, but in this case, as shown in FIG. The frame plate 7 will be sandwiched between two adjacent gabions. Therefore, when removing the surrounding frame 6 after stone filling, first remove the gabion main body 1.
Remove the frame plate 7 located on the free end side and remove the front and rear frame plates 8, 8, and then remove the adjacent gabion 5.
It may be removed by pulling out the frame plate 7 located between the frame plate 7 upward or sideways.In that case, by drilling a mounting hole 12 in the frame plate 7,
It can be easily removed by mechanical force via the attachment hole 12 or the wire attached thereto. Here, since the frame plate 7 is formed of a thin plate, no gap will be created between it and the adjacent gabion 5 after it is removed.

Note that the enclosing frame is not limited to one that can be disassembled as described above, and as shown in FIG. 2, each frame 20a,
The gabion main body 1 may be installed within the surrounding frame 20 by using the surrounding frame 20 in which the gabions 20b are fixedly connected to each other by means such as welding. In this case, after completion of the filling, the enclosure frame 20 can be removed by lifting it onto the top piece.

As explained above, in the present invention, filling stones are carried out with the four circumferences of the gabion main body reinforced by the surrounding frame,
Since the enclosing frame is then removed in the same position, the stone filling work and the subsequent pressurizing work of the filling stones can be carried out smoothly and efficiently, preventing deformation of the gabion body or movement of the filling stones. etc. can be reliably prevented, and the quality of the gabion can be improved. In addition, since the surrounding frame is provided around each gabion, there is no need for a long frame plate that spans a plurality of gabions, making it easy to handle and transport.
