Using a single caisson with a section formed, a plurality of the above caisson units are connected vertically to form a caisson wall, and the earth and sand in the ground contact part of this caisson wall is excavated and the caisson wall is moved to a predetermined position by its own weight. By sinking to a deep depth, a plurality of the caisson walls are combined into a cylindrical shape in the soil, while retaining concrete is poured into the gap on the outside of the caisson walls that have sunk, and only the formwork panels are removed. Pull it out of the soil, then
After the earth retaining concrete has developed a predetermined strength, the earth and sand in the cylinder formed by the plurality of caisson walls is excavated and the caisson walls are removed to the ground to form a continuous earth retaining wall using concrete. It is characterized by forming.

壁に接した状態で地下室を建設することができる。According to the prefabricated simple caisson and earth retaining method of the present invention,
After excavating the earth and sand on the ground surface of the caisson wall and letting the caisson wall sink to a predetermined depth under its own weight, concrete is poured into the gap on the outside of the caisson wall so that it is in contact with the outside surface of the frame. An earth retaining concrete wall is formed. Therefore, by sinking the caisson wall along the boundary with the adjacent land, an earth-retaining concrete wall is formed at the very edge of the boundary. Furthermore, by removing the caisson alone above ground, a basement can be constructed in contact with a continuous earth retaining wall formed of earth retaining concrete.

済むために広い敷地を確保する必要もなくなる。Furthermore, the soil on the ground surface of each caisson is excavated and the caisson sinks to a predetermined depth due to its own weight, so it does not affect the ground of adjacent land, and there is no need to use an auger, so a large site can be secured. There's no need to do that.
以下、本発明を図示の実施例に基づいて説明する。組立
て式簡易ケーソンAは、第1図に示すように複数個のケ
ーソン単体1を上下に連結して形成したケーソン壁体2
を筒状に組み合わせて構成されている。Hereinafter, the present invention will be explained based on illustrated embodiments. As shown in Fig. 1, the prefabricated simple caisson A has a caisson wall 2 formed by vertically connecting a plurality of caisson units 1.
It is constructed by combining them into a cylindrical shape.

防止するものである。The caisson unit 1 has a vertically long frame 1a as shown in FIG.
A form panel 1b is removably attached to the outer surface of the frame body 1a using attachment means, and a gap 1c for pouring earth retaining concrete is formed between the outer surface of the frame body 1a and the form panel 1b. has been done. The frame 1a is formed by stretching a metal plate over a frame made of square timbers. ld is a spacer that protrudes from the outer surface of the frame 1a and prevents the formwork panel 1b from curving toward the frame 1a due to earth pressure.
型枠パネルlbは、両端部付近がL字状に折り曲げられ
ていて土留コンクリートが間隙部ICから側方に流れ出
すをの防止している。The form panel lb is bent into an L-shape near both ends to prevent the retaining concrete from flowing out laterally from the gap IC.

1eが形成されている。枠体1aの寸法は、例えば縦寸
法180 cm、横寸法70cm、高さ寸法45cmす
るなど適宜設計しても良い。A blade-shaped portion 1e is formed at the lower end of the template panel 1b of the caisson unit 1 located at the lowest stage of the caisson wall body 2 to facilitate sinking. The dimensions of the frame 1a may be designed as appropriate, such as, for example, a vertical dimension of 180 cm, a horizontal dimension of 70 cm, and a height dimension of 45 cm.

緩めたボルト・ナツトを大径孔までに移動させてから孔
部から抜き取るようにする。The attachment means for attaching the formwork panel 1b to the frame body 1a is to provide holes (not shown) in the frame body 1a and the formwork panel 1b, respectively, and attach the formwork to the formwork using bolts and nuts (not shown) through these holes. The panel 1b is configured to be attached to the frame 1a. The above-mentioned hole portion is constituted by a vertically elongated elongated hole and a large-diameter hole located on the side of the elongated hole and large enough to allow a bolt or nut to be inserted therethrough, which are continuous to each other. Then, when sinking the caisson wall 2 into the soil, the bolts are placed in the long holes of the holes, and when the form panel lb is dug out on the ground, the loosened bolts and nuts are inserted into the large diameter holes. Move it and then pull it out from the hole.
なお、取付手段は、上述のようにケーソン壁体2の沈下
の際には型枠パネル2が枠体1aから外れず、沈下後に
枠体1aから外して土中から引き抜くことができるよう
に機能すれば、上記構成に限定はされず、適宜設計変更
できるものである。The attachment means functions so that the form panel 2 does not come off the frame 1a when the caisson wall 2 sinks, as described above, and can be removed from the frame 1a and pulled out of the soil after the caisson wall 2 sinks. Therefore, the configuration is not limited to the above configuration, and the design can be changed as appropriate.

To connect them, formwork panels ib are connected to each other using connecting plates 1f and bolts 1g, as shown in Fig.
A are also connected to each other as appropriate using Holt or the like.

First, the caisson wall 2 is placed close to the boundary A (the fourth

型枠パネルを順次引き抜く。Next, the earth and sand in the ground contact part of the caisson wall 2 is excavated with an excavator, etc., and the caisson wall 2 is lowered to a predetermined depth by its own weight (as shown in FIG. 4(C)), and the caisson 1 is further removed as appropriate. Add more and sink to the specified depth (Figure 4 (d) (
(shown in e)). Next, earth retaining concrete 3 is poured into the gap IC on the outside of the caisson wall 2, and the form panel 1b of the caisson wall 2 is pulled out of the soil before the earth retaining concrete 3 hardens (Fig. 4(f)). g)). Next, the other caisson walls 1b are sequentially lowered in the same manner, and the plurality of caisson walls 1b are assembled into a cylinder in the soil to form the caisson A. Meanwhile, earth retaining concrete is poured and the formwork panels are sequentially assembled. Pull it out.

The earth retaining concrete 3 is continuously formed along the outer periphery of the earth retaining concrete 3. After the earth-retaining concrete 3 has developed a predetermined strength, the earth-retaining concrete 3 is constructed by excavating the earth and sand opening in the caisson A, disassembling the caisson wall 2 into each frame 1a, and removing it to the ground. A cylindrical earth retaining continuous wall 4 is formed.
なお、施工順序は適宜変更できるものであり、例えば、
ケーソンAを土中に形成してから土留コンクリート3を
一度に打ち、その後金ての型枠パネル1bを引き上げる
ようにしても良い。Note that the construction order can be changed as appropriate; for example,
After the caisson A is formed in the soil, the retaining concrete 3 may be poured at once, and then the metal formwork panel 1b may be pulled up.

単体の形状や寸法を調整すれば、隣接地との境界が多少
複雑なものであっても対処できるという効果を奏する。As is clear from the above explanation, according to the prefabricated simple caisson and earth retaining method of the present invention, by sinking the caisson alone along the boundary with the adjacent land, it is possible to form a concrete wall at the very edge of the boundary. Furthermore, after removing the caisson wall above ground, it is possible to construct a basement next to the continuous earth retaining wall made of earth retaining concrete, making it possible to construct the basement to the boundary with the adjacent land, making the site more efficient for cultivation. This has the effect that it can be used for many purposes. Furthermore, by adjusting the shape and dimensions of the caisson itself, it is possible to deal with even somewhat complex boundaries with adjacent land.
更に、ケーソンは組立て式であり、土留コンクリートは
現場打ちであるので、運搬、搬入が容易となるという効
果を奏する。Furthermore, since the caisson is prefabricated and the earth retaining concrete is cast on site, it has the advantage of being easy to transport and bring in.

する。Furthermore, the earth and sand on the ground surface of each caisson is excavated and the caisson sinks to a predetermined depth due to its own weight, so there is no negative impact on the ground of the adjacent land, and no noise or vibration will cause a nuisance to the neighbors. This effect is achieved.
