るとされている。2. Description of the Related Art Conventionally, a retaining wall is classified into a reinforced concrete structure, a reinforced concrete structure, a kneading structure, etc. according to the material and shape. Thoroughly investigate and understand the impact,
Furthermore, it is considered important to consider related technical standards.
【０００３】更に、各種擁壁の分類と共に概要について
説明するものとする。先ず、従来より広く用いられてい

及び線形を自由に変化させることができ、のり止及び構
造物との取り合いなどが容易であるという特徴がある。Further, an outline will be explained together with classification of various retaining walls. Firstly, concrete block retaining walls and Machiishi retaining walls, which have been widely used in the past, are simple retaining walls in which concrete blocks or Machi stone are stacked. And the linearity can be changed freely, and it is easy to prevent gluing and to engage with structures.
【０００４】次に、重力式擁壁があり、これは擁壁自体

コンクリート造のものがある。Next, there is also a leaning type retaining wall, which is an intermediate type between a concrete block structure / sight stone type retaining wall and a gravity type / semi-gravity type retaining wall. Like a retaining wall, it cannot stand on its own,
Mainly used for cut soil, and there are reinforced concrete and reinforced concrete structures.

この種の擁壁で高さのある擁壁を構築することは不経済
である。Next, there is a semi-gravity type retaining wall, which is similar to the gravity type retaining wall, but in order to save the amount of concrete, a small amount is provided near the rear surface of the retaining wall against the tensile force generated in the body. It was made to put the rebar of and to resist. Here, since the only element that resists the earth pressure applied to the semi-gravity type retaining wall together with the gravity type is the weight of the wall body of the retaining wall itself,
It is uneconomical to build a tall retaining wall with this type of retaining wall.

て小さくてすむものである。Subsequently, there is also a cantilever type retaining wall, which is composed of a vertical wall and a bottom slab, and its structural type includes an inverted T type and an L type. In addition, the wall has a reinforced concrete structure, and this type of retaining wall can effectively use the weight of backfill soil, and the cross section of the wall can be smaller in the gravity type than in the semi-gravity type.

のである。Furthermore, there is a retaining wall type retaining wall, which is an improvement of the cantilever type retaining wall in that the earth pressure increases as the height of the retaining wall increases, resulting in an uneconomical cross section. hand,
A triangular retaining wall is inserted between the back wall of the vertical wall of the cantilever type retaining wall and the bottom slab, and the vertical wall and the bottom slab are fixed on three sides.

った。Problems to be Solved by the Invention The construction surface of various retaining walls other than the Machichi stone retaining wall described in the above-mentioned conventional description has a color unique to concrete, presenting an artificial landscape, and time passes. However, there is a problem that the natural landscape is significantly impaired over a long period of time because the property does not change and it is not greened.

難しいという問題があった。In addition, the sillite stone retaining wall described in the above-mentioned section of the prior art, the sillice stone used for the retaining wall has a surface side length of 25 cm to 40 cm and a length of 35 cm.
It is a truncated pyramid shaped stone with a size of centimeters to 60 centimeters or more, and it needs to be carefully quarried so that there are no irregularities on each side, and it takes a very long time to process,
There is a problem that it is difficult to secure a large amount of philanthropic stones while satisfying the same standards.

があった。Although not described in detail in the section of the prior art, the types of masonry include masonry masonry, field stone masonry, miscellaneous masonry, and stone masonry. Although the name is changed according to the degree of processing to stone, the one with a lower degree of processing to stone had lower adhesion to the stones in the masonry, and there was a safety problem because the retaining wall work was dangerous. .

The natural stones are arranged in parallel with each other at a predetermined interval by the natural stones that are connected and connected to each other by the rope body via the turnbuckle between the grip anchors of the pair of natural stones. Backfill material is backfilled on the back side of the slope formed by stone, and earth and sand are created between the backfill materials, and the rope body is stretched with the turnbuckle and rolled with the earth and sand. In addition to the rolling process of pressing and then adjusting the height with the natural stone that is the filling material in preparation for the stacking of the next stage natural stone,
The gist is to form a stone wall by repeating the above-mentioned natural stone placement step and rolling step according to the set gradient. Furthermore,
The above construction method is known as a widely known technique. It is also possible to combine the treatment of infiltrated water with a water permeable pipe and the filling of backfill concrete from the gap between the natural stones piled up as described above.

る。Further, according to the method for constructing a masonry retaining wall according to the present invention, even if the construction volume per day is high, the construction method wall can be protruded to the front like a normal kneading and retaining wall. Since it does not exist, there is also an effect that the retaining wall can be constructed continuously.

手が容易であるという効果もある。Next, the natural stone used in the method for constructing a masonry retaining wall according to the present invention does not need to be processed into a truncated pyramid shape like Machichi stone, and has a size as a natural stone. Also, since it is not necessary to strictly adjust, there is an effect that it can be easily obtained as a material.

With the natural stones that are connected and connected by ropes via the natural stones, the natural stones are arranged in parallel at a predetermined interval, and the backing material is lined on the back side of the slope formed by the natural stones. In addition to forming the earth and sand between the backing materials, the compaction process of rolling the rope body with the turnbuckle in the stretched state together with the constructed earth and sand, and then stacking the natural stone in the next stage. It is characterized in that the height is adjusted by a natural stone that is a filling material, and a retaining wall is formed by repeating the step of arranging the natural stone and the rolling step according to a set gradient.
