DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag for constructing a wall and an earth wall construction method using the bag for constructing a wall.

[0002]

2. Description of the Related Art Conventionally, as one form of a mud wall construction method, a bag filled with soil, a so-called sandbag, is arranged side by side along the extension direction of the mud wall to be constructed at a mud wall construction site.
The step of constructing the wall forming part of the first step, and then performing embankment on the back side of the wall forming part of the first step by approximately the same height as the wall forming part, sequentially to a predetermined earth wall forming height. There is a construction method that repeatedly goes to build an earth wall.

[0003]

However, in the above earth wall construction method, the wall portion is affected by the earth pressure due to the backfill, and the earth pressure increases in proportion to the height of the wall portion. Therefore, when the wall portion is formed high, it is easy to collapse, and in general, the soil wall formation height can be constructed only at about 3 m at most.

[0004]

SUMMARY OF THE INVENTION Accordingly, in the present invention, there is provided a bag body to be filled with a filler such as soil or crushed stone, and a connection provided at least at each of a front edge of an upper end and a lower end of the bag body. An object of the present invention is to provide a bag for wall surface construction, comprising: a hole; and a connecting body that connects adjacent bag bodies in the left-right direction or the vertical direction through the connecting hole.

[0005] The present invention also has the following features.

[0006] (1) To provide a reinforcing body which is detachably or integrally connected to the bag body for reinforcing the earth wall to be constructed.

(2) The bag body is formed in a substantially rectangular parallelepiped shape.

The present invention is also characterized by the following earth wall construction method using the above-described wall construction bag. In other words, the first-stage wall-forming portion is formed by arranging the bag for wall construction according to any one of claims 1 to 3 side by side along the extension direction of the earth wall to be constructed on the earth wall construction site. The embankment is constructed by embankment on the back side of the first-stage wall forming portion by substantially the same height as the same wall-forming portion, and on the first-stage wall forming portion, according to any one of claims 1 to 3, The wall-building pouches are arranged side by side, and the wall-building pouches adjacent to each other in the left-right direction or the up-down direction are connected to each other by a connection body through a connection hole, and integrated with the first-stage wall formation portion. The second-stage wall forming part is constructed, and the back side of the second-stage wall forming part is buried by the same height as the same wall forming part, and the above operations are sequentially performed to a predetermined earth wall forming height. Going repeatedly to build mud walls.

Further, in the present invention, in the above-mentioned wall forming part of the second or more steps in the earth wall construction method, a predetermined wall construction bag is provided with a reinforcing member, and each reinforcing member is placed in a substantially horizontal state. It is also characterized by being placed in the embankment.

[0010]

Embodiments of the present invention will be described below.

That is, the bag body for wall surface construction according to the present invention is provided on a bag body for filling a filler such as soil or crushed stone, and at least on each front side edge of the upper and lower ends of the bag body. It has a connection hole and a connection body that connects adjacent bag bodies in the left-right direction or the up-down direction through the connection hole.

In this way, the wall portions can be constructed by arranging the wall-constructing bags side by side in the left-right direction and stacking the wall-constructing bags thereon.

The integrated and strong wall portion can be quickly and easily constructed.

Further, the bag for building a wall surface has a reinforcing member detachably or integrally connected to the bag body for reinforcing the earth wall to be built.

By embedding the reinforcing member in the embankment to be filled behind the wall in this way, when the earth pressure of the embankment acts on the wall, the embankment is connected to the wall. A pull-out resistance (frictional resistance) during embankment is generated in the reinforcement, and the pull-out resistance opposes the earth pressure of the embankment, thereby preventing the wall portion from collapsing.

The bag body of the bag for building a wall is formed in a substantially rectangular parallelepiped shape.

In this manner, the work of arranging and stacking the wall-constructing bags in the left-right direction and the up-down direction can be performed simply and reliably.

Furthermore, since the bag body is formed in a substantially rectangular parallelepiped shape and has a constant depth, the self-weight of the bag body is increased to secure a large frictional resistance force received by itself. And the bag body can be

The earth wall construction method according to the present invention, which is performed using the above-described bag for wall surface construction, is as follows.

The first-stage wall forming section is constructed by arranging any one of the above-mentioned wall-building bags along the extension direction of the clay wall to be constructed at the earth wall construction site.

On the back side of the first-stage wall forming portion, an embankment is buried at substantially the same height as the same wall-forming portion.

The first to third wall-forming portions are provided on the wall forming portion.
Along with juxtaposing the wall construction bags described in any of the above,
The side wall forming bags adjacent in the left-right direction or the up-down direction are connected to each other by a connecting body via a connecting hole, and a second-stage wall forming portion integrated with the first-stage wall forming portion is constructed.

On the back side of the second-stage wall forming portion, an embankment is buried at substantially the same height as the same wall-forming portion.

The above-mentioned operations are sequentially repeated up to a predetermined earth wall forming height to construct an earth wall.

In this way, the wall portion can be easily constructed by the wall-constructing bag, and the wall-constructing bags are interconnected and integrated, so that a strong wall portion can be constructed. Can be.

Further, in the present invention, in the above-mentioned second or higher wall forming portion in the earth wall construction method, a predetermined wall construction bag is provided with a reinforcing member and each reinforcing member is placed in a substantially horizontal state. Are placed in the embankment.

[0027] In this way, by making each reinforcement body be in a state of being narrowed in the embankment, the wall portion is connected to the wall surface portion when receiving earth pressure from the embankment filled behind it. The pull-out resistance (friction resistance) during embankment is generated in the reinforcing body, and the pull-out resistance opposes the earth pressure of the embankment, and the overall resistance of the wall portion against the earth pressure of the embankment is reduced. Increase. As a result, it is possible to prevent the wall portion from being collapsed, and it is possible to construct the earth wall at least twice as high as the conventional earth wall height (about 3 m).
