DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone-walled structural wall provided for protecting slopes and walls in mountains, roads, residential areas, and the like, and protecting coasts in rivers.

[0002]

2. Description of the Related Art Structural walls provided for protection of slopes and walls in mountains, roads, residential areas, and the like, and protection of coasts in rivers, etc. are relatively simple and require less labor than conventional methods. Often formed of concrete,
In rare cases, it was formed using a stone basket. The biggest problems in constructing such a structural wall are how to quickly and efficiently discharge the moisture in the back soil, and how to effectively control the slip of the back soil to reduce the land. It is about stabilization. However, the concrete structure wall has poor water permeability, so that moisture easily accumulates in the back soil, and when the moisture accumulates, the entire area of the back soil liquefies, increasing the earth pressure and causing landslides and collapse of the structure wall. There was a problem. Moreover, since the concrete structure wall is flat and the wall surface is smooth as a whole, the soil retaining effect for suppressing the slip of the back soil is poor, and the soil effect is further reduced when the back soil contains moisture. On the other hand, the stone-walled basket-structured wall is made of wire mesh baskets filled with stones, so it excels in permeability and quickly removes moisture in the back soil. Not only is it possible to drain water, but the friction between the soil and the back soil is large, and it excels at the soil retaining effect that suppresses landslides. However, the conventional stone-walled structure wall is generally formed by arranging a plurality of stone-walled baskets neatly up and down and left and right, so that the front and rear wall surfaces are formed to be substantially flat. The contact area with the back soil is small,
It was difficult to say that the water permeability and soil retaining functions were fully utilized effectively.

[0003]

SUMMARY OF THE INVENTION It is a main object of the present invention to provide a stone-walled structure wall in which the drainage effect and the soil retention effect are enhanced by increasing the contact area with the back soil.

[0004]

According to the present invention, there is provided, in accordance with the present invention, a plurality of stone stuffing baskets having stuffed stones therein arranged side by side on the left and right, and a plurality of stacked vertically stacked stones. On the back side of the stone basket, part of the stone basket belonging to any row or step is projected from the wall surface into the back soil, and the entire outer peripheral surface of the protrusion is brought into contact with the back soil. There is provided a structural wall made of stone baskets.

[0005] According to the structural wall of the present invention having the above structure, a part of the stone basket is projected into the back soil on the back side, so that the contact area between the structural wall and the back soil is increased. Since the entire peripheral surface of the projecting portion is added as the drainage surface, the drainage effect is enhanced, and the locking force between the back soil and the structural wall is enhanced, so that landslide is reliably suppressed and the soil retention effect is improved. In addition, since all of the stone baskets belonging to one row or step do not project, but only some of the stone baskets are projected, the entire outer periphery of the protruding portion is securely in contact with the back soil. Not only can the water permeation area be efficiently expanded, but also the back soil can be securely locked to this protruding portion in all directions, up and down, left and right, and more efficient soil retention The effect can be obtained.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 3 show a first embodiment of a structural wall according to the present invention. The structural wall 1A includes a plurality of rectangular parallelepiped square stone baskets 2 arranged side by side on the left and right, and a plurality of vertically stacked piles.
On the back side of the building, some stone stuffing baskets 2
The outer peripheral surface of the protruding portion 2 a is brought into contact with the back soil 3.

The stone stuffing basket 2 is made of a net-like material such as a diamond-shaped wire mesh, a welding wire mesh, or reinforced plastic, and is filled with stones such as natural stones. When projecting, the corresponding stone basket is formed to have a longer dimension in the front-rear direction than the other one, and a part of its rear end is projected from the wall surface. In this case, instead of projecting all the stone baskets 2 belonging to one row or step, only a part of the stone baskets among the stone baskets 2 belonging to the row or step are selectively projected. It is also desirable that the adjacent ones in the up-down or left-right direction be prevented from protruding at the same time as much as possible, and it is desirable to protrude one by one with at least one space therebetween.

The structural wall 1A having the above-mentioned structure has a structure in which a part of the stone stuffing basket 2 protrudes into the back soil 3 on the back side thereof, so that the structure wall 1A has a substantially flat wall surface. Since the contact area between the structural wall 1A and the back soil 3 is greatly increased, and the drainage is performed through each of the protrusions 2a,
The drainage effect is significantly improved. Also, the back soil 3 and the structural wall 1
Since the locking force with A is increased, landslide is reliably suppressed, and the soil retaining effect is greatly improved. In addition, since all of the stone baskets 2 belonging to one row or step are not projected, but only a part of the stone baskets are projected, the entire outer periphery of each protruding portion 2a is securely connected to the back soil 3. Not only can the water permeation area be efficiently expanded, but also the back soil 3 can be securely locked to the protruding portion 2a in all directions, up and down, and left and right. An efficient retaining effect can be obtained. In each of the stone baskets 2, vertically and horizontally adjacent ones can be connected to each other by appropriate means.

FIG. 4 shows a second embodiment of the present invention.
In the structural wall 1B of this embodiment, a plurality of short stone baskets 2 and 2 are arranged in the longitudinal direction at positions where the stone baskets should project, and the rear end of the stone basket 2 at the rear end projects from the wall surface. And a projection 2a.

FIG. 5 shows a third embodiment of the present invention.
The structure wall 1C of this embodiment is different from the structure walls of the first and second embodiments in that a part of the rear end of the stone stuffing basket 2 partially projects from the wall surface. 2 is different from those in that it is disposed in a state protruding from the wall surface to form a protruding portion 2a. In this case, it is desirable that at least the stuffing basket 2 protruding from the wall surface and the stuffing basket 2 located in the wall surface in front of the stuffing basket 2 are connected to each other by an appropriate connection fitting 4.

FIG. 6 shows a fourth embodiment of the present invention.
The structure wall 1D of this embodiment is different from the structure walls of the first to third embodiments in that the structure wall is substantially vertically constructed, but is installed in an inclined state. In this case, as a method of projecting the stone basket 2 from the wall surface to form the protruding portion 2a, those disclosed in the first to third embodiments are used alone or in combination. In each of the above embodiments, a square stone basket is used, but other shapes such as a cylindrical stone basket can also be used.

[0012]

As described above, according to the present invention, a part of the stone stuffing basket is projected into the back soil on the back side of the structural wall, and the entire outer peripheral surface of the projection is brought into contact with the back soil. The contact area between the structural wall and the back soil is greatly increased, the water permeable area is increased, the drainage effect is improved, and the locking force between the back soil and the structural wall is increased, and landslide is reliably suppressed, The retaining effect is also improved.
