Description of the Related Art Conventionally, as shown in FIG. 7, this type of stone-filled basket-type structural wall installed for protection of slopes and greening in hills, valleys, roads, residential areas, river banks, and the like, as shown in FIG. A stone stuffing basket 1 containing a filling material such as earth and sand or rubble is inserted into a slope 2
Is known in which a plurality of steps are stacked in a stair-like shape.
Such a structural wall is composed of a wire mesh and the stone basket 1 that composes it is filled with earth and sand, gravels, and the like, so that it has excellent water permeability and removes moisture in the back soil. Not only can water be drained quickly, but also the friction between the soil and the back soil is large, and the soil retaining effect that suppresses landslides is superior.

As shown in FIG. 7, the slope 2 is cut in advance in a stepwise manner in accordance with the height of the stone basket 1, and the rear end portion of the stone basket 1 is sequentially placed on each step 2a for stacking. Alternatively, as shown in FIG. 8, the slope 2 is cut into an inclined surface so that the earth and sand 3 behind the stone basket 1 is backfilled every time the stone basket 1 for one stage is installed. Construction was very troublesome. Moreover, since the upper and lower stone baskets 1, 1 are stacked in an unstable state due to a shift in the front-rear direction, the connection must be strengthened accordingly, and the connection work between the stone baskets is also required. It was troublesome.

点もあった。Further, when the structural wall is installed on a bank of a river or the like, a sheet-shaped suction prevention material is installed between the slope and the stone basket in order to prevent the outflow of earth and sand from the slope. But
In this case, since the suction-preventing member must be installed while being bent in a stepwise manner, not only is the installation operation troublesome, but also the use area is increased and the cost is increased.

必要に応じて相互に連結する。The method of constructing the structural wall will be described in more detail. First, after the back net 13 is stretched along the slope 11 as described above, the back 12e for opening the lowermost stone basket 12 is provided. The rear end is arranged so as to be in contact with the back net 13, and the rear end thereof is connected to the back net 13 with an appropriate connection metal fitting, and
2e is closed. Then, all or a part of the mesh of the upper surface 12b or the front surface 12d of the stone basket 12 is opened to fill the inside with a filler such as earth and sand or gravels. When the stone baskets 12 are arranged side by side in the horizontal direction, the stone baskets adjacent horizontally are connected to each other as necessary.

結する。Next, the second-stage stone basket 12 is installed in the same manner, and is connected to the lower stone basket 12. At this time, the upper-stage stone basket 12 is connected to the lower-stage stone basket 12 while being almost completely placed on the upper surface thereof. When the stone baskets 12 are also installed in the horizontal direction, adjacent stone baskets are connected to each other as necessary, as in the case of the first stage.
【0019】以下、第3段目以降の石詰篭12を同様の

単に行うことができる。By arranging the structural wall 10A in this manner, the slope 11 is cut in a stepped manner as in the prior art, and the earth and sand behind the stone stuffing basket is filled every time the stone stuffing basket is installed one step. There is no need to return, and the installation work can be performed easily and quickly. Moreover, while the upper stone basin is almost completely stacked on the upper surface of the lower stone basin,
Since the stacked stone baskets 12 are integrally connected by one back net 13, the stacked state is very stable, the connection strength is large, and the work of connecting the upper and lower stone baskets to each other is easy. Can be done.

As shown in (1), it can be stretched on a slope by being supported by a wire rope. In this figure, a back net 13 having a lateral length spanning three stone baskets 12,
The vertical ropes 15 and the horizontal ropes 16 fixed to the slope 11 are connected at appropriate positions by connecting metal fittings 17 such as helical wires, so that they are sequentially stretched along the slope 11. When the wire rope is used as described above, the workability is very good when a back net having a large area is stretched or when a plurality of back nets are stretched simultaneously or sequentially.

である。FIG. 4 shows a second embodiment of the structure wall made of stone baskets. The structure wall 10B of the second embodiment differs from the first embodiment in that the bottom surface 12a and the back surface 12e are different. The point is that an open stone basket 12 is used. That is, as shown in FIG. 5, the stone stuffing basket 12 has an upper surface 12b and left and right side surfaces 1b.
2c and the front surface 12d are covered by a screen mesh,
2e and the bottom surface 12a are open, and these stone baskets 12 are vertically stacked and connected to each other so that the lower surface 12a of the upper stone basket 12 is the upper surface 12 of the lower stone basket 12.
b. In other words, the mutually contacting surfaces of the adjacent stone baskets 12 are made into one surface by a common surface network.

However, the lowermost stone stuffing basket 12 may be one in which a mesh is stretched on the bottom surface 12a as used in the first embodiment. In this case,
It is not necessary to extend the lower end 13b of the back net 13 to the bottom surface 12a of the lowermost stone basket 12.

The structure wall 10B can be installed economically. When the stone baskets 12 are arranged side by side in the horizontal direction, the surfaces of the stone baskets 12 adjacent to each other that are adjacent to each other can be made into a single plane by a common screen net.
