2. Description of the Related Art Conventionally, as a method of installing a stone filling body, at least one pair of notched grooves for passing a reinforcing branch line on both sides substantially matching the inner peripheral side surface of each of a plurality of gabion bodies arranged at predetermined locations has been known. After the formed protection frame is erected, and after the stone is filled into the gabion main body through the protection frame, a reinforcing branch line is inserted from above the cutout groove and attached to the gabion bone line. ,
There is a facility provided by removing the protective frame (see JP-A-5-140946).

[0003]

However, in the prior art described above, as importance is placed on maintaining and restoring the natural environment, there is a demand for various stone-filled bodies (stone-filled bodies such as gabions) in river construction and the like. In view of the current situation where stones are increasing, each side piece of the gabion can be supported without deformation when stuffing stones, but there is a problem that it is not suitable for large-sized stone stuffing facilities. The present invention has been made in view of such circumstances,
Eliminate the disadvantages of the prior art, even when using a construction machine to perform the installation work of various stone gabions with a simple configuration,
An object of the present invention is to provide an installation method of a stone gabion that facilitates the erecting of the stone gabion and that allows the stone gabion to be lifted and moved without damaging a net, a frame line, etc., and without breaking its shape. It is assumed that.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and employs the following technical means. A gabion with a bottom reinforcement frame line attached to the outside of a large gabion consisting of the bottom surface and the side surfaces excluding the top surface can form a frame line or a trunk line at any point on the top frame of the gabion. If both the frame line and the trunk line are suspended with a lifting wire rope hanging down from the hanging frame, the gabion and the packing stone, etc. are integrated so that the gabion and the packing stone are not deformed. In a stone gabion that is lifted and moved, separate protection frames divided into several pieces are set up as a group in a large gabion, and each protection frame, packing stone, and gabion are lifted and moved together. Technical means were adopted.

[0005]

According to the present invention, by employing the above technical means, it is possible to reliably prevent deformation of the frame and trunk of the gabion when the stone is hand-packed or machine-packed with a simple structure. In addition, the lifting device allows the protective frame, the filling stone, and the gabion to be lifted and moved together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. First, the first embodiment of the protective frame 2 will be described in detail with reference to FIG. 1. The protective frame 2 substantially matches the inner peripheral side surface of the gabion 1, and has no bottom surface and upper surface. At least one pair of notched grooves 6 slightly higher than the depth and slightly longer than the depth of the gabion upward from the lower end of the side surface are formed on two opposing side surfaces. It is also possible to provide one or more pairs of the notched grooves on adjacent and opposing side surfaces, and to provide the branch lines at right angles. In addition, as long as the height is higher than the depth of the applicable gabion 1, the upper limit is arbitrary as long as it is not inconvenient in use. The phrase “substantially coincides with the inner peripheral side surface of the gabion” means that the relationship between the inner dimension of the side surface of the gabion 1 and the outer dimension of the side frame 3 of the protective frame 2 is such that the protective frame 2 is not tightly pulled out. If the difference is too large, it affects the amount of packing stones, which is not preferable. It goes without saying that the shape of the cutout groove 6 can be arbitrarily designed in various ways. Since the supporting portion is formed on the upper portion of the protective frame 2, the gabion 1 provided with the protective frame 2 is filled with stone, and then the supporting portion of the protective frame 2 is gripped and removed. Then, on the bottom surface of the gabion 1, each side surface except the top surface and the bottom surface of the gabion 1 is erected with the respective side surfaces of the protective frame close to each other.
Assembly is simple and reliable. Further, the protection frame body is erected on the inside of the gabion that has been almost completely assembled, so that the gabion can be more reliably erected. Alternatively, a protective frame is erected on the bottom of the gabion, and the side of the gabion 1 is assembled depending on the protective frame.
Is easy to assemble. In stuffing stones, especially by mechanical stuffing, the protective frame prevents damage to the net and frame lines of the gabion 1 and keeps the gabion 1 in shape. Further, depending on the size of the gabion, etc., the protection frame may be divided into several parts and may be erected in groups. Thus, in the gabion 1, the protective frame, and the filling stone that have been filled with stone, the filling stone compresses each side of the protective frame sideways. Each side surface of the protective frame presses each side of the gabion 1 sideways by the elastic force of the protective frame. Since the side surfaces of the gabion 1 are connected to each other, the side surfaces of the protective frame body press the packing stone without expanding laterally beyond the inner diameter of the gabion 1. Since the descent of the filling stone is reduced in synergy with the friction of the filling stone, the side surface of the gabion 1 is kept relatively flat, and the bottom surface of the gabion 1 does not deform. This, combined with the fact that each side of the formwork presses the filling stone, allows the gabion 1 with the inner formwork to be filled with the filling stone and gently lifted. When it is expected that the bottom surface of the gabion 1 is deformed depending on the shape and size of the gabion 1 and the type of the filling stone, an appropriate number of partitions for controlling the filling of the gabion 1 may be provided in the gabion 1. In this case, a "protective frame having a cutout groove" as disclosed in JP-A-5-140946 is used. Since the lower side and both sides of the partition are connected to the side and bottom surfaces of the gabion 1, the posture of the filling stone can be maintained and the bottom surface of the gabion 1 does not bulge downward. The gabion 1 and the protection frame body after the filling are simultaneously lifted, moved to a predetermined position, and installed. After that, it is preferable to pull out the protective frame upward, shape the upper surface of the filling stone, and connect the upper cover to the gabion. Further, a gabion 1 provided with a protective frame 2
After the stone is filled, the reinforcing branch line 7 is inserted by using the notch groove 6 to be connected to the bone line 4 or the like of the gabion 1, and thereafter, a locking member such as a hook which is effective when extracting is protected. The shape, quantity, and position are appropriately selected and attached to the upper part of the frame 2.
The material of the protective frame 2 is preferably a metal, but any material such as wood and reinforced plastic material can be used as long as strength is possible, and the surface may be roughened to reinforce the material.

Next, a method of installing the gabion 1 will be described. The gabion 1 is provided by using a gabion 1 having a protective frame 2 as shown in FIG. The protection frame 2 is erected, and stones are filled inside the protection frame 2 manually or by mechanical power such as a power shovel or a bulldozer. After the filling, the notch grooves 6 provided on both sides of the protection frame 2 are used. And the reinforcing branch line 7 is inserted through the bone line 4 of the gabion 1
Alternatively, the reinforcing branch line 7 prevents the stone from being swelled outward and deformed by the pressure of the stone by being bound to the trunk net 5. Utilizing the loops formed on the nets on the two opposite sides of the gabion 1, the lifting hardware 8 is inserted, and wires 9 and the like are hung on both ends of the lifting metal 8 and lifted by a crane or the like. Move and set up a stone gabion. The protective frame 2 is suspended from the stone gabion thus installed, and is manually or mechanically lifted and removed by using a suspending member. By repeating this, facilities will be installed on slopes and embankments. Furthermore, a gabion 1 filled with these stones
The facility is completed by closing and binding the lid net.
The above description has been made of the case where the stone gabion 1 provided with the protection frame 2 having the notch groove 6 is used.
It is needless to say that a conventional inner mold without the above may be used. Next, a second embodiment will be described with reference to FIG. Hanging fittings 11 are provided on four sides or two opposing faces of a rectangular frame 10, and the hanging fittings 11 are used to be lifted and moved by using the trunk line 12 or the frame line 13 of the stone-filled gabion. . The third embodiment will be described with reference to FIG. 3. The bottom reinforcement frame 14 is further provided in the second embodiment, and the bottom reinforcement frame 14 may have four sides.
It goes without saying that only two opposite sides may be used. Next, a fourth embodiment will be described with reference to FIG. As described above, in the first to third embodiments, the protective frame 2 is higher than the height of the gabion 1. On the other hand, the fourth embodiment is for a low case. Needless to say, the same height may be used.
Finally, a fifth embodiment will be described with reference to FIG.
The protection frame 2 is divided into one large gabion 15 and used in groups. For lifting, the lifting is performed by using the hanging bracket 11 of the rectangular frame 10 described in the second embodiment. Things. Although the various embodiments have been described above, various designs can be changed as long as they can be lifted and moved through the gauze trunk line, the frame line or the bottom reinforcement frame line using the hanging metal fittings. It is.
