Description

[Detailed description of the invention] [Field of industrial application] The present invention is a gabion facility used to prevent deformation and damage to gabions during stone filling when constructing gabions on slopes, embankments, etc. This relates to personal protective equipment.

[Prior Art] Generally, when installing a rectangular gabion called a futon gagion, an opening for stone filling is provided on the top surface of the gabion placed in advance at a predetermined facility location, and the gabion is filled through this opening. Stone filling was carried out manually or by mechanical force such as a power shovel or bulldozer, but during stone filling and pressure work after stone filling, the gabion could move and shift its position, or its sides could be There were inconveniences such as bulging and deformation.

Therefore, in order to avoid the above-mentioned inconvenience, the present applicant proposed the
No. (Utility Model Application No. 60-96423) proposed a protective device that prevents deformation of the gabion during stone filling by surrounding the four sides of the gabion from the outside.
Although this makes it possible to reliably prevent displacement and deformation of the gabion, there is a problem in that it is difficult to close the opening after filling with stones.

That is, when the opening is formed by separating some adjacent row lines from each other on the upper surface of the rectangular tube-shaped body net, the closing of the opening is This is done by inserting a common bone line through the zigzag-shaped bent portion of the two row lines to close the openings, and tying both ends of the bone line to the frame lines at both ends of the gabion. The protective equipment becomes an obstacle, making it difficult to insert the bone lines into the column lines and tie them to the frame lines, and in some cases this must be done after removing the protective equipment. Therefore, if the protective equipment is removed before the opening is closed, there is a risk that the gabion will be deformed due to movement of the filling stones, etc.

Further, the gabion has a box shape with the top completely open, and after filling with stones, a top screen is attached to the opening on the top surface, and the ends of each row line of the top screen are tied to the gabion. Even in such a structure, the protective equipment becomes an obstacle, making it difficult to connect the row wires.

[Problems to be solved by the invention] The present invention is capable of reliably supporting the gabion facility protector so that each side piece of the gabion is not deformed during stone filling, and which can be installed while the gabion is still enclosed in the gabion. The technical problem is to construct a gabion in such a way that the opening of the gabion can be closed.

[Means for Solving the Problems] The present invention provides a protective equipment for gabion facilities including a rectangular enclosing frame that surrounds and supports the gabion, and the enclosing frame:
A lower frame having at least one pair of opposing side walls shorter than the gabion, and a lower frame separably installed on the lower side pieces of the lower frame and dimensioned so that the side pieces are taller than the gabion. The above-mentioned problem was solved by constructing an upper frame with an upper frame.

[Function/Effect] By enclosing the protective equipment configured as described above around the gabion and filling it with stones through the opening provided on the top surface of the gabion, deformation of the gabion can be reliably prevented. be able to.

Further, the work of closing the opening on the top surface of the gabion after filling with stones is performed by removing the upper frame of the surrounding frame to expose the upper end of the gabion.

By removing the lower frame after completing the closing operation of the opening, the gabion can be installed in an extremely stable state without being deformed.

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

First, in FIG. 1, reference numeral 1 indicates a gabion called a futon basket formed of, for example, a diamond-shaped wire mesh. It is shaped like a rectangular box with an opening 3 on its top surface for stone filling, and after filling the inside with stones manually or using mechanical force such as a power shovel or bulldozer, the opening 3 is filled with stones. The upper surface netting 4 is to be attached thereto. This top screen 4 is attached by connecting both ends of each row line 6 in the top screen 4 to the frame lines 5b attached to the upper edges of the side pieces 2b, 2b, and This is done by connecting the side ends of the side pieces 2c, 2c to the frame lines 5c, 5c of the upper edges of the side pieces 2c, 2c.

The protective device 10 that surrounds and supports the gabion 1 to prevent its deformation during stone filling is a rectangular surrounding frame that surrounds and supports the gabion 1, as shown in FIGS. 2 and 3. 11, and a rectangular covering frame 12 that protects the upper edge of the gabion 1. It consists of an upper frame 11b that is separably installed on top of the gabion 11a and increases the size of the enclosing frame to be taller than the gabion 1, and the frame plates constituting the lower frame 11a and the upper frame 11b are as follows: Made of iron, aluminum alloy, etc., in order to minimize the gap between adjacent gabions when constructing gabions one after another, the gabions should be made as thin as possible within the range that provides the necessary reinforcing strength. After filling the gabion 1 with stones, it can be removed by lifting it upward.

Further, the covering frame 12 is formed into a rectangular frame shape by four groove-shaped frame pieces provided with grooves 13, and the grooves 13 are fitted to the upper end of the surrounding frame 11. It is installed on 11.

Gabion 1 using protective equipment 10 having the above configuration
When the gabion 1 is filled with stones, the gabion 1 is stored in the protective device 10 as shown by the chain line in FIG.
Stone is then filled into the container by hand or using earth-moving machinery such as a power shovel or bulldozer. At this time, since the periphery of the gabion 1 is supported and reinforced from the outside by the surrounding frame 11, the gabion will not be deformed such as bulging outward during stone filling or when pressurized after stone filling. Moreover, the pressing of the packed stones is carried out uniformly and efficiently, and furthermore, since the upper edge of the periphery of the gabion 1 is protected by the cover frame 12, the stones do not remain in the gabion 1 even when the stones are loaded by the machine. A direct collision with the upper edge is prevented, and the gabion is not crushed downward, causing deformation or damage.

When the stone filling is completed in this way, the cover frame 12 and the upper frame 11b are removed, the upper end of the gabion 1 is exposed as shown in FIG. 4, and the upper surface net 4 is covered.
Both ends of each row line 6, 6, .
The left and right side ends of are connected to the frame line 5c (Fig. 1).
Thereafter, the surrounding frame 11 is pulled upward and removed, thereby completing the installation of the gabion.

By successively installing new gabions adjacent to the gabions installed in this manner, a large number of gabions can be constructed.

In the above embodiment, the lower frame 11a is formed lower than the gabion 1 on all four side walls, and the rectangular upper frame 11b is attached to the lower frame 11a.
However, only a pair of opposing side walls of the lower frame 11a, that is, the side walls 14, 14 (FIG. 2) located at the end of the row line in the upper screen 4, are made low in height, and these An independent plate-shaped upper frame may be superimposed only on the side walls 14, 14.

In addition, when using any of the above-mentioned types of surrounding frames, the upper frame and the cover frame can be formed integrally.

It goes without saying that the protective equipment 10 can also be used in gabion facilities of the type in which openings are provided in the upper surface of the square tube-shaped trunk net by separating some adjacent row lines from each other. Nor.
