[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone-filled cage mat suitable for use in revetment works, riverbed works and the like, and a construction method therefor.

[0002]

2. Description of the Related Art In disaster prevention and conservation projects such as river rehabilitation and coastal improvement, a revetment method mainly consisting of a concrete covering method has been generally used from the viewpoint of strength. However, recently, along with the growing public awareness of the importance of preserving the natural environment, the revision of the conventional construction methods for river improvement and coastal improvement has been emphasized.

One of these reviewed construction methods is the jade cage method. This is a method of placing stones in a cylindrical or quadrangular cage made of wire mesh and installing them on site, and is excellent in strength, compatibility with topography and nature, water permeability, etc. Although there is an advantage that the construction method is simpler and cheaper than the covering method by the above, the conventional Jacquard construction method assembles a number of independent gabions one after another, stone-fills them and installs them side by side or in sequence on the site. Because it was a thing,
There is a drawback that it takes a lot of manpower and time for assembling the gabion, stone filling, and laying work.

In order to eliminate such drawbacks, a plurality of stone filling areas are provided by connecting a plurality of baskets or by sequentially connecting a bottom net and a side net which are a part of the basket. Another method is to form a vast cage structure (hereinafter referred to as a "car mat"), machine it with stones, and then attach a top net.

However, the above conventional car mat has
A large number of independent cages or bottom nets and side nets are lined up one by one, and they are sequentially connected by wire or coiled connecting wires, so the connecting work is cumbersome and inefficient. However, there is a drawback that the workability is poor.

Embodiments of the present invention will now be described in detail with reference to the drawings. The car mat 1 shown in FIG.
The front and rear and left and right side nets 11 and 12 and the upper surface net 13 form a rectangular cage as a whole, and the inside is divided into a plurality of stone-filled regions by the partitioning net 14, and the inner four corners and the middle Small stone auxiliary baskets 15 and 16 in place
It has a volume equivalent to multiple regular-sized rectangular baskets (futon baskets), and is a place where the entire bed, embankment, etc. is almost flat with stones inside, as shown in Fig. 2. Is installed in.

The car mat 1 is assembled and laid as follows. That is, first, a single large bottom net 10 that spreads over the entire car mat is spread and disposed at a predetermined location. It is desirable that the connecting frame lines 18 are attached to the four sides of the bottom net 10 by inserting them into a mesh or a ring formed at the end of the mesh line, and the ends of the adjacent frame lines are connected to each other. Further, it is desirable to previously attach the frame line 19 to the attachment position of the partitioning net 14.

Next, small stone-filling auxiliary cages 15 and 16 are formed at appropriate positions in the middle and between the four corners of the bottom net 10. These auxiliary cages 15 and 16 are formed by placing a rectangular basket having a required size on the bottom net 10 and connecting it to the bottom net 10 by a connecting means such as a wire or a spiral connecting wire. Alternatively, it may be formed by arranging a cylindrical frame body in which wire nets are connected in a square tubular shape whose upper and lower surfaces are open and standing on the bottom surface net 10 and attaching the bottom surface net 10. Also,
The auxiliary car 15 at the four corners and the auxiliary car 16 in the middle may have the same volume or different volumes.

When the auxiliary cages 15 and 16 are completed, the auxiliary cages 15 and 16 are respectively filled with stones to stabilize the bottom mesh 10 at the positions of the auxiliary cages 15 and 16 and then the bottom meshes. Front and back and left and right side nets 11 on each side of 10,
11 and 12, 12 are attached respectively. Even if the side nets 11 and 12 are long nets each having a length corresponding to each side of the bottom net 10 as shown in the figure, a plurality of short nets shorter than that side are connected to each other to have a length corresponding to each side. In either case, both end portions of the side nets 11 and 12 are connected to the auxiliary cages 15 at the four corners by appropriate connecting means, and the middle portions of the side nets 11 and 12 are intermediate. The auxiliary cage 16 is connected, and then the lower ends of the side nets 11 and 12 are connected to the frame line 18 on each side of the bottom net 10 for attachment.

When fixing the ends of the side nets 11 and 12 to the auxiliary cars 15 at the four corners as described above, the ends of the side nets 11 and 12 are connected to the ends of the auxiliary car 15 as shown in FIG. Alternatively, as shown in FIG. 4, it may be attached so as to overlap with the auxiliary car 15, and in the case of being installed so as to overlap, the side nets 11 and 1 adjacent to each other at the corners of the car mat as shown in the drawing.
The two ends are connected to each other. Also, the left and right side nets 1

Although it is desirable to attach a frame line 20 for connecting the side end portions of the four side nets 4, the side nets 12, 12 are connected to the partition net 14.
When a plurality of short nets having a length equal to the installation interval are connected to each other, the frame line connecting the short nets can also be used as the connecting frame line of the intermediate partition net 14.

Thus, by mounting the side nets 11 and 12 inside the auxiliary cages 15 and 16 in a stone-filled state,
Not only is the bottom net 10 stable and easy to install, but also after the end nets and middle parts of the side nets 11 and 12 are connected to and supported by the stone-filled auxiliary baskets 15 and 16, respectively. By connecting the lower ends of the side nets 11 and 12 to the bottom net 10, the side nets 11 and 12 do not tilt or swing stably, so that the connecting work can be performed easily and quickly. You can

Next, when the side nets 11 and 12 have been attached, the car mat 1 is placed between the side nets 12 and 12 facing each other.
A partition net 14 for partitioning the inside of the into a plurality of stone filling areas is attached. The partitioning net 14 is attached to the bottom netting 10 and the side nets 12 and 12 at the attachment positions of the frame lines 19 and 20, and the lower end portion thereof is attached to the frame line 1 of the bottom net 10.
9 by connecting both end portions to the frame lines 20 of the side nets 12 and 12, respectively.

Subsequently, each of the stone filling areas is filled with stones by using a mechanical force of a power shovel or the like, and one upper surface net 13 extending from the top to the entire surface of the car mat is provided. A frame line 21 is attached to each of the four sides of the upper surface net 13, and a frame line 22 is also attached to a position corresponding to the intermediate partition net 14, and the side nets 11, 1 are attached to these frame lines 21, 22.
If the upper ends of the two and the partition nets 14 are connected to each other and the upper ends of the auxiliary cars 15 and 16 are connected to the corresponding positions, the attachment becomes easy.

Thus, by laying the required number of car mats 1 one after another, river improvement, coastal improvement, etc. are performed.

The side nets 11 and 12 and the partition net 14
Like the bottom net 10 and the top net 13, each of the surrounding sides is provided with a frame line.
