Description

本発明は、土木構造物形成用袋体及びこの土木構造物形成用袋体を用いた土木構造物に関し、特に、切り土等の斜面安定化工法等に代表される土木工法に広くかつ好適に用いることができる土木構造物形成用袋体及びこの土木構造物形成用袋体を用いた土木構造物に関するものである。   The present invention relates to a civil engineering structure forming bag and a civil engineering structure using the civil engineering structure forming bag, and is particularly suitable for civil engineering methods represented by slope stabilization methods such as cut soil. The present invention relates to a civil engineering structure forming bag that can be used and a civil engineering structure using the civil engineering structure forming bag.

切り土等の斜面を安定化する工法には、例えば、切り土等の斜面安定化工法に用いる受圧板や切り土法面保護工法（例えば、特許文献１〜３参照）、複数の土嚢を並べてなる地盤補強構造物を用いる地盤補強方法（例えば、特許文献４参照）、マット状の袋型枠等を用いて中詰めにコンクリート等を充填しているダム貯水池等の水中部の法面保護工法（例えば、特許文献５参照）等がある。
これらの工法では、十字形状又はそれを連結した連続十字形状もしくは格子形状の構造物を用いて地盤表面の補強や地盤内部の補強を行っている。 For the method of stabilizing the slope of cut soil, for example, a pressure receiving plate used for the slope stabilization method of cut soil, a cut slope protecting method (for example, see Patent Documents 1 to 3), and a plurality of sandbags are arranged. A ground reinforcement method using a ground reinforcement structure (see, for example, Patent Document 4), a slope protection method for underwater areas such as a dam reservoir filled with concrete or the like using a mat-like bag formwork, etc. (See, for example, Patent Document 5).
In these construction methods, the ground surface is reinforced or the ground interior is reinforced by using a cross-shaped structure or a continuous cross-shaped or lattice-shaped structure connecting them.

地盤補強を行うための十字形状や、それを連結した連続十字形状又は格子形状の構造を作る方法としては、一般に筒状のジオテキスタイルを十字、連続十字状又は格子状にあらかじめ形成し、柔軟でコンパクトにできるそれらの材料を施工現場に持ち込み、ジオテキスタイル内部にモルタルや泥水のような固体粒子を含む流動性材料を充填して硬化又は固化させることにより構造物を形成し、地盤表面の補強や地盤内部の補強に用いる方法が知られている。   As a method of creating a cross shape for reinforcing the ground, or a continuous cross shape or a lattice shape structure connecting them, generally a tubular geotextile is formed in advance into a cross shape, a continuous cross shape or a lattice shape, and is flexible and compact. These materials can be brought into the construction site, and the geotextile is filled with a flowable material containing solid particles such as mortar and muddy water to be hardened or solidified to form a structure. A method used for reinforcement is known.

筒状のジオテキスタイルを十字又は連続十字、格子状に形成する手段としては、上記の技術のほかに、ホース形状の筒状織布を十字又は格子状に重ねてその交点を接続部材で固定したもの、ホース状の筒状織布を「く」の字状に折り曲げ、曲がり部同士を接続部材で固定したもの、シート状のジオテキスタイルを十字形状又は格子形状に切断して２枚重ね合わせ、縫製加工したもの等がある（例えば、特許文献６〜７参照）。   In addition to the above technique, the tubular geotextile can be formed into a cross or continuous cross, in a grid pattern. In addition to the above technique, a hose-shaped cylindrical woven fabric is stacked in a cross or grid pattern and the intersection is fixed with a connecting member. , Hose-shaped tubular woven fabric is folded into a "<" shape and the bent parts are fixed to each other with a connecting member. Sheet-shaped geotextile is cut into a cross shape or a lattice shape, and two sheets are stacked and sewn (For example, refer to Patent Documents 6 to 7).

また、本件出願人は、図１１に示すように、切り土等の斜面安定化工法に用いる受圧板用袋体を出願している。この受圧板用袋体は、筒状織布Ａのほぼ中央に筒状織布Ｂの織幅に略一致する長さで２箇所の切れ目を入れ、その切れ目に筒状織布Ｂを挿入して、筒状織布Ａに筒状織布Ｂを貫通させ、筒状織布Ａの前記切れ目の縁近傍と該切れ目に当接する筒状織布Ｂの表面を接合させ、筒状織布Ａの内部に位置する筒状織布Ｂ表面に、筒状織布Ｂ内部から筒状織布Ａ内部に通じる孔を設け、筒状織布Ｂにはモルタル注入口を設けている（特許文献８参照）。   Further, as shown in FIG. 11, the applicant of the present application has applied for a pressure receiving plate bag body used in a slope stabilization method such as cut soil. In this pressure receiving plate bag body, two cuts are made at a length substantially equal to the woven width of the tubular woven fabric B at the substantially center of the tubular woven fabric A, and the tubular woven fabric B is inserted into the cut. Then, the tubular woven cloth B is passed through the tubular woven cloth A, the vicinity of the edge of the cut of the tubular woven cloth A and the surface of the tubular woven cloth B contacting the cut are joined, and the tubular woven cloth A The surface of the tubular woven fabric B located inside is provided with a hole leading from the inside of the tubular woven fabric B to the inside of the tubular woven fabric A, and the tubular woven fabric B is provided with a mortar inlet (Patent Document 8). reference).

しかしながら、筒状織布を十字状又は格子状に重ねてその交点を接続部材で固定したものは、モルタル等の流動性材料を注入した場合、当然のことながら重ね合わせた部分が同一平面にならず、地盤表面で使用するには、交差部において一方の筒状織布が地表から浮き上がるという問題があり、また、地中で用いる場合も、梁として考えた場合は重ね方によって縦方向と横方向で曲げ剛性の強弱が発生するという問題があった。
また、ホース形状の筒状織布を「く」の字状に折り曲げ、曲がり部同士を接続部材で固定したものは、同一平面内に構造体が形成されるが、曲がり部の形状が直角に近くなるため、その部分で筒状織布が折れてしまい内部が閉塞する。そのため、固体粒子を含む流動性材料を充填しようとすると、閉塞部で固体粒子が詰まってしまい、筒状織布全体に充填することができなくなる。その対策として、曲がり部分の内部には空間を保持する形状保持材が装填されていることが多いが、形状保持材が入っているとコンパクトに折りたたむことができず、柔軟であるというジオテキスタイルのメリットが生かせなくなる上、コストアップにもつながる。
そして、シート状のジオテキスタイルを十字形状又は格子形状に切断して２枚重ね合わせ、縫製加工したものは、当然ながら多くの縫製部又は接着部を有しており、内部に充填する流動性材料の圧力が上がると縫製部又は接着部に剥離力が加わり、破損しやすいという欠点があった。
また、一定直径の筒状織布ＡとＢを用いて十字を形成する方法では、縫製加工も少なく繊維も十字の各方向に連続してつながっていることから、固体粒子を含む流動性材料を充填して硬化又は固化させて構造物を形成した場合、筒状織布を構成している繊維が構造物の強度に寄与するものの、図１１に示すように、筒状織布の交差部では、該交差部の対角線の２倍の周長まで各々の筒状織布が膨らむため、筒状織布Ａの切れ目近傍と筒状織布Ｂの接合部に無理な引張り力が加わり、破断しやすくなる。さらに、接合部で筒状織布ＡとＢを直接縫い合わせて加工する場合は、縫い代が十分に取れず、加工上の品質確保が困難であった。

However, when it is used on the ground surface, there is a problem that one cylindrical woven fabric is lifted from the ground surface at the intersection. There is a problem that bending rigidity is generated in the direction.
In addition, when a hose-shaped tubular woven fabric is bent into a "<" shape and the bent portions are fixed with a connecting member, a structure is formed in the same plane, but the shape of the bent portion is at right angles. Since it becomes close, the tubular woven fabric breaks at that portion and the inside is blocked. Therefore, when trying to fill a fluid material containing solid particles, the solid particles are clogged at the closed portion, and the entire tubular woven fabric cannot be filled. As a countermeasure, shape bending materials that hold the space are often loaded inside the bent part, but if the shape holding material is included, it cannot be folded compactly, and the merit of geotextile that it is flexible Can not be used, and also leads to cost increase.
A sheet-shaped geotextile cut into a cross shape or a lattice shape and overlapped and stitched has, of course, a large number of sewing parts or adhesive parts. When the pressure is increased, a peeling force is applied to the sewn part or the bonded part, and there is a drawback that it is easily damaged.
Further, in the method of forming a cross using the cylindrical woven fabrics A and B having a constant diameter, since there are few sewing processes and the fibers are continuously connected in each direction of the cross, a fluid material containing solid particles is used. When the structure is formed by filling and curing or solidifying, the fibers constituting the tubular woven fabric contribute to the strength of the structure, but as shown in FIG. Since each tubular woven fabric swells up to twice the circumference of the diagonal line of the intersecting portion, an excessive tensile force is applied to the vicinity of the cut of the tubular woven fabric A and the joined portion of the tubular woven fabric B, resulting in breakage. It becomes easy. Furthermore, when the tubular woven fabrics A and B are directly stitched and processed at the joint portion, the seam allowance is not sufficient, and it is difficult to ensure the quality in processing.

A connecting portion formed by joining the other tubular woven fabric in contact with the other tubular woven fabric by sewing or an adhesive; a hole communicating with the inside of the tubular woven fabric and an inlet for a fluid material; Is provided.

この場合において、前記開口部を、他の筒状織布の織幅に略一致する長孔としたり、他の筒状織布の直径に略等しい直径を有する孔とすることができる。   In this case, the opening can be a long hole that substantially matches the woven width of another cylindrical woven fabric, or a hole that has a diameter substantially equal to the diameter of the other cylindrical woven fabric.

また、複数本の筒状織布を略平行に配設し、該筒状織布の大径部に他の筒状織布を接合又は貫通させることができる。   Further, a plurality of cylindrical woven fabrics can be arranged substantially in parallel, and another cylindrical woven fabric can be joined or penetrated through the large-diameter portion of the cylindrical woven fabric.

また、上記土木構造物形成用袋体を用いる本発明の土木構造物は、上記土木構造物形成用袋体を構成している複数の筒状織布の中に、順に流動性材料を注入して構築したことを特徴とする。   Further, in the civil engineering structure of the present invention using the civil engineering structure forming bag, a fluid material is sequentially injected into a plurality of cylindrical woven fabrics constituting the civil engineering structure forming bag. It is characterized by having built.

本第１発明の土木構造物形成用袋体によれば、経糸及び緯糸からなる筒状織布に直径が他の部分より大きい大径部を設けた異径筒状織布の前記大径部に開口部を形成するとともに、該開口部に他の筒状織布の端部を縫製や接着剤により接合した接合部を備え、該他の筒状織布に筒状織布の内部と連通する孔と流動性材料の注入口とを設けることから、筒状織布同士の接合部は膨らんだときに無理な荷重がかからず、比較的高い圧力で筒状織布内に流動性材料を注入しても破損することがなく、比較的高い圧力で注入することができ、筒状織布にはプリテンションがかかって織布を構成している糸の屈曲による初期伸びがなくなり、構造体として使用した場合に高い剛性を発揮することができる。
また、大径部の直径の大きさを利用して筒状織布が３本以上交差する構造を作ることができ、これにより、３次元的な立体構造を形成することができ、立体的に十字乃至格子を組んだ構造は従来の布型枠でも例がないことから新たな布型枠の用途を期待することができる。 According to the civil engineering structure forming bag of the first invention, the large-diameter portion of the different-diameter tubular woven fabric in which the tubular woven fabric made of warp and weft is provided with a large-diameter portion larger in diameter than the other portions. An opening is formed in the opening, and a joint is formed by joining an end of another tubular woven fabric to the opening by sewing or an adhesive , and the other tubular woven fabric communicates with the inside of the tubular woven fabric. Since the joints between the tubular woven fabrics are swelled, an excessive load is not applied and the flowable material is placed in the tubular woven fabric with a relatively high pressure. Can be injected at a relatively high pressure without being damaged, and the tubular woven fabric is pre-tensioned so that there is no initial elongation due to bending of the yarns constituting the woven fabric. When used as a body, it can exhibit high rigidity.
In addition, a structure in which three or more cylindrical woven fabrics intersect using the size of the diameter of the large-diameter portion can be made, thereby forming a three-dimensional structure, and three-dimensionally Since there is no example of a conventional cloth formwork with a cross or lattice structure, a new use of the cloth formwork can be expected.

この場合、前記他の筒状織布が、端部に直径が他の部分より大きい大径部を備えた異径筒状織布からなることにより、筒状織布との接合部を筒状織布の大径部によく沿わせることができ、これにより、接合部での括れを防止し、また、大径部が縫製代となるため縫製加工も容易にすることができる。 In this case, the other tubular woven fabric, the Rukoto such heterogeneous diameter cylindrical fabric diameter end with a larger large diameter portion than the other portions, the tubular joints of the tubular woven fabric The large-diameter portion of the woven fabric can be well aligned, thereby preventing the constriction at the joint portion, and the large-diameter portion serves as a sewing allowance, so that the sewing process can be facilitated.

また、本第２発明の土木構造物形成用袋体によれば、経糸及び緯糸からなる筒状織布に直径が他の部分より大きい大径部を設けた異径筒状織布の前記大径部に少なくとも一対の相対向する開口部を形成するとともに、該開口部に他の筒状織布を貫通させ、前記筒状織布の開口縁部と該開口縁部に当接する前記他の筒状織布とを縫製や接着剤により接合した接合部を備え、該他の筒状織布に筒状織布の内部と連通する孔と流動性材料の注入口とを設けることから、筒状織布同士の接合部は膨らんだときに無理な荷重がかからず、比較的高い圧力で筒状織布内に流動性材料を注入しても破損することがなく、比較的高い圧力で注入することができ、筒状織布にはプリテンションがかかって織布を構成する糸の屈曲による初期伸びがなくなり、構造体として使用した場合に高い剛性を発揮することができる。
また、大径部の直径の大きさを利用して筒状織布が３本以上交差する構造を作ることができ、これにより、３次元的な立体構造を形成することができ、立体的に十字乃至格子を組んだ構造は従来の布型枠でも例がないことから新たな布型枠の用途を期待することができる。 According to the civil engineering structure forming bag of the second aspect of the present invention, the large-diameter tubular woven fabric having a diameter larger than that of the other portion is provided on the tubular woven fabric made of warp and weft. At least a pair of opposed openings are formed in the diameter portion, and another tubular woven fabric is passed through the opening, and the other edge of the tubular woven fabric is in contact with the opening edge of the tubular woven fabric. Since the tubular woven fabric is provided with a joint portion joined by sewing or an adhesive , and the other tubular woven fabric is provided with a hole communicating with the inside of the tubular woven fabric and an inlet for the fluid material, The joint between the tubular woven fabrics is not subjected to an excessive load when it swells, and even if a fluid material is injected into the tubular woven fabric at a relatively high pressure, it does not break, and the relatively high pressure The tubular woven fabric is pre-tensioned and the initial elongation due to bending of the yarns that make up the woven fabric is eliminated. High rigidity when used as can be exhibited.
In addition, a structure in which three or more cylindrical woven fabrics intersect using the size of the diameter of the large-diameter portion can be made, thereby forming a three-dimensional structure, and three-dimensionally Since there is no example of a conventional cloth formwork with a cross or lattice structure, a new use of the cloth formwork can be expected.

この場合、前記開口部を、他の筒状織布の織幅に略一致する長孔としたり、他の筒状織布の直径に略等しい直径を有する孔とすることにより、筒状織布同士の接合強度を向上させることができる。   In this case, the opening portion is a long hole that substantially matches the woven width of the other tubular woven fabric, or a hole having a diameter substantially equal to the diameter of the other tubular woven fabric, so that the tubular woven fabric is The joint strength between them can be improved.

また、複数本の筒状織布を略平行に配設し、該筒状織布の大径部に他の筒状織布を接合又は貫通させることにより、本発明の土木構造物形成用袋体を、受圧板を始めとする各種土木構造物の形成に広く適用することができる。   In addition, the civil engineering structure forming bag of the present invention is provided by arranging a plurality of cylindrical woven fabrics substantially in parallel and joining or penetrating another cylindrical woven fabric to the large diameter portion of the cylindrical woven fabric. The body can be widely applied to the formation of various civil engineering structures including pressure receiving plates.

また、上記土木構造物形成用袋体を用いる本発明の土木構造物によれば、筒状織布に充填した流動性材料が硬化した後は、他の筒状織布の内部から当該他の筒状織布に接合した別の筒状織布の内部に通じる孔を介して、固化した流動性材料が連続した構造物になるため、設計上も適切な形状及び強度を有する構造物となり、例えば、グランドアンカーの斜面への定着のための反力構造物として有効に機能し、長年の使用に亘って構造物表面のクラック等による欠けの発生を防止することができる。   Moreover, according to the civil engineering structure of the present invention using the above-described bag for forming a civil engineering structure, after the fluid material filled in the cylindrical woven fabric is cured, the other Since the solidified fluid material becomes a continuous structure through a hole leading to the inside of another cylindrical woven fabric joined to the cylindrical woven fabric, it becomes a structure having an appropriate shape and strength in terms of design, For example, it effectively functions as a reaction force structure for fixing to the slope of the ground anchor, and it is possible to prevent the occurrence of chipping due to cracks on the surface of the structure over many years of use.

以下、本発明の土木構造物形成用袋体及びこの土木構造物形成用袋体を用いた土木構造物の実施の形態を、図面に基づいて説明する。   Embodiments of a civil engineering structure forming bag body and a civil engineering structure forming bag body according to the present invention will be described below with reference to the drawings.

図１に、本発明の土木構造物形成用袋体の第１実施例を示す。
この土木構造物形成用袋体は、筒状織布Ａに直径が他の部分より大きい大径部２を設け、該大径部２に開口部３を形成するとともに、該開口部３に他の筒状織布Ｂの端部２１を接合し、該他の筒状織布Ｂ又は筒状織布Ａに流動性材料の注入口（図示省略）を設けている。 FIG. 1 shows a first embodiment of a civil engineering structure forming bag according to the present invention.
In this civil engineering structure forming bag body, the cylindrical woven fabric A is provided with a large-diameter portion 2 having a diameter larger than other portions, and an opening 3 is formed in the large-diameter portion 2, and the opening 3 is provided with other portions. The other end 21 of the tubular woven fabric B is joined, and the other tubular woven fabric B or the tubular woven fabric A is provided with an inlet (not shown) for a fluid material.

筒状織布Ａ、Ｂは、直径１００ｍｍの筒状部１と直径１５０ｍｍの球状の大径部２を有した透水性を有する異径筒状織布であり、円周方向の糸はスパイラル状に連続して織り込まれている。大径部２の直径は、その周長が筒状織布Ａの筒状部１の√２倍以上になっていることが望ましい。
筒状織布Ａ、Ｂは、経糸・緯糸ともポリエステル繊維で太さは１５００ｄ／３本、密度は経１０．３本／ｃｍ、緯５．５本／ｃｍで織組織は平織りである。環状織機で織られており、緯糸が筒状織布Ａ、Ｂの前記スパイラル状の糸を構成する。 The cylindrical woven fabrics A and B are water-permeable different-diameter cylindrical woven fabrics having a cylindrical portion 1 having a diameter of 100 mm and a spherical large-diameter portion 2 having a diameter of 150 mm, and the thread in the circumferential direction is spiral. Is woven continuously. As for the diameter of the large diameter part 2, it is desirable for the circumference to become 2 times or more of the cylindrical part 1 of the cylindrical woven fabric A.
Tubular woven fabrics A and B are both warp and weft polyester fibers with a thickness of 1500 d / 3, a density of warp 10.3 / cm, and a weft of 5.5 / cm, and the weave structure is plain weave. It is woven by an annular loom, and the weft yarns constitute the spiral yarns of the cylindrical woven fabrics A and B.

図１に示すように、筒状織布Ａの大径部２には相対する位置に２箇所、長さ１５０ｍｍの円形の孔からなる開口部３が設けられており、他の筒状織布Ｂは大径部２で切断され、端部２１が各々前記筒状織布Ａの開口部３に接合されている。
筒状織布Ａの開口部３と該開口部３に当接する他の筒状織布Ｂ表面の接合は、縫製によるものである。
他の筒状織布Ｂは、筒状部１のみで構成された直線状のものでもよいが、筒状部１よりも直径が大きな大径部２を有する異径筒状織布の大径部２を切断したものとすると、球状の大径部２同士の縫製となるので、他の筒状織布Ｂの切断面が筒状織布Ａの大径部２によく沿い、縫製部で括れが発生せず、また、大径部２が縫製代となるので縫製加工自体も容易である。 As shown in FIG. 1, the large-diameter portion 2 of the tubular woven fabric A is provided with openings 3 made of circular holes having a length of 150 mm at two opposite positions, and other tubular woven fabrics. B is cut at the large-diameter portion 2, and the end portions 21 are joined to the opening portions 3 of the tubular woven fabric A, respectively.
The joining of the opening 3 of the tubular woven fabric A and the surface of the other tubular woven fabric B contacting the opening 3 is by sewing.
The other tubular woven fabric B may be a straight one composed only of the tubular portion 1, but the large diameter of the different diameter tubular woven fabric having the large diameter portion 2 having a larger diameter than the tubular portion 1. If the portion 2 is cut, the spherical large-diameter portions 2 are sewn together, so that the cut surface of the other tubular woven fabric B is well along the large-diameter portion 2 of the tubular woven fabric A, Necking does not occur and the large diameter portion 2 becomes a sewing allowance, so that the sewing process itself is easy.

この袋体を用いて土木構造物を形成するには、筒状織布Ａ又はＢにモルタル等の流動性材料の注入口（図示省略）を設け、そこから流動性材料を注入する。
この場合、各筒状織布Ａ、Ｂの端部は折り返して縫製加工により閉じておき、この状態で、モルタルポンプと注入ホースにより注入口からモルタルを充填する。注入されたモルタルは、筒状織布Ａ、Ｂの交差部を通って他の筒状織布Ｂ内部にも充填され始め、最終的に筒状織布Ａ、Ｂ内に完全に充填されれば、注入口から注入ホースを取り除いて注入作業は完了する。
モルタルは一般的なポルトランドセメントを用いた通常品を使用し、注入圧力をやや高めに設定することにより、織布の織目を通してモルタルの水分を脱水させ、織布内のモルタルを緻密にして早期に硬化させ、ブリージング等による硬化後の体積減少がないようにする。注入圧は０．３ＭＰａ程度が適当である。
硬化後の体積減少がほとんどない特殊モルタルを使用した場合は、脱水の必要がないので注入圧力は少し低くても構わないが、斜面等の傾斜地に袋体が設置されている場合、ある程度の圧力をかけないと、水平方向に配置されている筒状織布の断面形状がモルタルの自重で歪な形にとどまってしまう。断面略円形にするためには０．１ＭＰａ程度の注入圧力が必要である。
また、筒状織布Ａ、Ｂの表面に耐候性を付与するための樹脂等が加工されている場合は、脱水できないので、硬化後の体積減少がない特殊モルタルを使用する。 In order to form a civil engineering structure using this bag, an injection port (not shown) of a fluid material such as mortar is provided in the cylindrical woven fabric A or B, and the fluid material is injected therefrom.
In this case, the ends of the tubular woven fabrics A and B are folded back and closed by sewing, and in this state, the mortar is filled from the injection port with the mortar pump and the injection hose. The injected mortar begins to be filled into the other tubular woven fabrics B through the intersections of the tubular woven fabrics A and B, and finally is completely filled into the tubular woven fabrics A and B. If so, the injection hose is removed from the injection port to complete the injection operation.
The mortar is a normal product using general Portland cement, and by setting the injection pressure slightly higher, the moisture in the mortar is dehydrated through the texture of the woven fabric, and the mortar in the woven fabric is made dense and early. To prevent volume reduction after curing due to breathing or the like. A suitable injection pressure is about 0.3 MPa.
When using special mortar that hardly loses volume after curing, the injection pressure may be a little lower because there is no need for dehydration. Otherwise, the cross-sectional shape of the cylindrical woven fabric arranged in the horizontal direction will remain in a distorted shape due to the weight of the mortar. In order to make the cross section substantially circular, an injection pressure of about 0.1 MPa is required.
In addition, when a resin or the like for imparting weather resistance is processed on the surfaces of the cylindrical woven fabrics A and B, special mortar that does not decrease in volume after curing is used because it cannot be dehydrated.

筒状織布Ａ、Ｂは実施例１と同じであるが、図２に示すように、接合は下記の手順で行う。筒状織布Ａの開口縁部と該開口縁部に当接する筒状織布Ｂの接合は、縫製によるもので、開口縁部の筒状織布Ｂと筒状織布Ａの大径部２とを短く折り返して共に重ね、筒状織布Ａの切れ目に沿って一周又は一周以上縫製する。   The tubular woven fabrics A and B are the same as those in the first embodiment, but as shown in FIG. The joining of the opening edge portion of the tubular woven fabric A and the tubular woven fabric B contacting the opening edge portion is by sewing, and the large-diameter portion of the tubular woven fabric B and the tubular woven fabric A at the opening edge portion. 2 are folded back and overlapped together and sewed one or more times along the cut line of the tubular woven fabric A.

かくして、本第１、第２各実施例の土木構造物形成用袋体は、筒状部１と該筒状部１の直径よりも大きな大径部２を有する筒状織布Ａの大径部２に開口部３を設け、他の筒状織布Ｂの端部２１を該開口部３に接合することから、接合部が膨らんだときの寸法で接合され、図１１に示す従来例のような接合部での無理な引張り力が発生せず、縫製加工も縫製代が確保されることで容易になり、製品としての信頼性が向上するほか、筒状織布が一定直径以下に括れてしまうことがない。
また、このような構造の袋体は、接合部の断面積が確保されるので、袋体のどの部分からモルタル等の固体粒子を含む流動性材料を注入してもスムーズに充填され、簡単に構造体が形成できる。
そして、施工場所へ、袋体をコンパクトにたたんで持ち込むことができ、さらに、袋体は軽量であるため運搬に重機を必要とせず、現場立地条件が悪い場合でも施工が容易になる。 Thus, the civil engineering structure forming bag of each of the first and second embodiments has the large diameter of the tubular woven fabric A having the tubular portion 1 and the large diameter portion 2 larger than the diameter of the tubular portion 1. Since the opening part 3 is provided in the part 2 and the end part 21 of the other tubular woven fabric B is joined to the opening part 3, the joint part is joined with the dimensions when the joint part swells, and the conventional example shown in FIG. Such an excessive tensile force is not generated at the joint, and the sewing process is facilitated by securing the sewing allowance, improving the reliability of the product, and the tubular woven fabric is tied to a certain diameter or less. There is no end.
Moreover, since the cross-sectional area of the joint portion is ensured in the bag body having such a structure, even if a fluid material containing solid particles such as mortar is injected from any part of the bag body, the bag body can be filled smoothly and easily. A structure can be formed.
The bag can be folded compactly and brought into the construction site. Further, since the bag is lightweight, no heavy equipment is required for transportation, and the construction is easy even when the site location conditions are poor.

図３に、本発明の土木構造物形成用袋体の第３実施例を示す。
この土木構造物形成用袋体は、直径が他の部分より大きい大径部２を備えた筒状織布Ａの大径部２に少なくとも一対の相対向する開口部３を形成するとともに、該開口部３に、直径が他の部分より大きい大径部２を備えた他の異径筒状織布Ｂを貫通させ、大径部２同士を重ねた状態で前記筒状織布Ａの開口縁部と該開口縁部に当接する前記他の筒状織布Ｂとを接合し、該他の筒状織布Ｂに筒状織布Ａの内部と連通する孔４と流動性材料の注入口（図示省略）とを設けている。 FIG. 3 shows a third embodiment of the civil engineering structure forming bag of the present invention.
This civil engineering structure forming bag has at least a pair of opposed openings 3 in the large-diameter portion 2 of the tubular woven fabric A having a large-diameter portion 2 having a larger diameter than the other portions. The opening of the tubular woven fabric A with the large-diameter portions 2 overlapped with each other by passing through the opening 3 the other different-diameter tubular woven fabric B having a larger-diameter portion 2 larger in diameter than the other portions. The edge 4 and the other tubular woven cloth B that contacts the opening edge are joined, and the hole 4 communicating with the inside of the tubular woven cloth A and the flowable material are connected to the other tubular woven cloth B. An inlet (not shown) is provided.

筒状織布Ａ、Ｂは、共に直径１００ｍｍの一定径の筒状部１と直径１５０ｍｍの球状の大径部２を有した透水性を有する異径筒状織布からなり、円周方向の糸はスパイラル状に連続して織り込まれている。
筒状織布Ａ、Ｂは、経糸・緯糸ともポリエステル繊維で太さは１５００ｄ／３本、密度は経１０．３本／ｃｍ、緯５．５本／ｃｍで織組織は平織りである。環状織機で織られており、緯糸が筒状織布の前記スパイラル状の糸を構成する。 The tubular woven fabrics A and B are both made of a different diameter tubular woven fabric having water permeability having a cylindrical portion 1 having a constant diameter of 100 mm and a spherical large-diameter portion 2 having a diameter of 150 mm. The yarn is continuously woven in a spiral shape.
Tubular woven fabrics A and B are both warp and weft polyester fibers with a thickness of 1500 d / 3, a density of warp 10.3 / cm, and a weft of 5.5 / cm, and the weave structure is plain weave. It is woven by an annular loom, and the weft yarn constitutes the spiral yarn of the tubular woven fabric.

図３に示すように、筒状織布Ａの大径部２には相対する位置に２箇所、開口部３として長さ１５０ｍｍのスリットが設けられており、筒状織布Ｂがそのスリットを貫通して筒状織布Ａの大径部２内に筒状織布Ｂの大径部２が介装されるように組み立てられている。筒状織布Ａの前記スリットの縁近傍と該スリットに当接する筒状織布Ｂの表面との接合は、接着剤によるものである。
他の筒状織布Ｂは、筒状部１のみで構成された直線状のものでもよいが、その場合は、筒状織布Ａと筒状織布Ｂの交差部において、筒状織布Ｂの背面と筒状織布Ａ内面との間にモルタル等の流動性材料を十分に充填することが好ましく、さらに筒状織布間の接合個所には剥離力が働くので、接合は縫製加工であることが必要である。 As shown in FIG. 3, the large-diameter portion 2 of the tubular woven fabric A is provided with two slits having a length of 150 mm as the opening portions 3 at opposite positions, and the tubular woven fabric B has the slits. The large-diameter portion 2 of the tubular woven fabric B is assembled so as to pass through the large-diameter portion 2 of the tubular woven fabric A. The bonding between the vicinity of the edge of the slit of the tubular woven fabric A and the surface of the tubular woven fabric B that is in contact with the slit is by an adhesive.
The other tubular woven fabric B may be a straight one constituted only by the tubular portion 1, but in that case, at the intersection of the tubular woven fabric A and the tubular woven fabric B, the tubular woven fabric It is preferable that a fluid material such as mortar is sufficiently filled between the back surface of B and the inner surface of the tubular woven fabric A. Further, since a peeling force acts on the joint between the tubular woven fabrics, the joining is performed by sewing. It is necessary to be.

また、同図に示すように、筒状織布Ｂ内部から筒状織布Ａ内部に通じる孔４は、筒状織布Ａ内部に面した筒状織布Ｂの側面に２箇所設けられ、寸法は直径５０ｍｍである。筒状織布Ｂの一端に設けた流動性材料の注入口は、逆止弁が備えられているような通常よく用いられるものでよい。
筒状織布Ａ、Ｂの各端部は、折り返されて縫製加工により閉じられている。この状態で、モルタルポンプと注入ホースにより、注入口から流動性材料として、例えば、モルタルを充填する。注入されたモルタルは、筒状織布Ｂに充填されていき、交差部を超えた時点で筒状織布Ｂ内部から筒状織布Ａ内部に通じる孔４を介して筒状織布Ａにも充填され始める。
そのため、交差部では、筒状織布Ｂの十分膨らんだ状態が保たれつつ筒状織布Ａにモルタルが充填されていく。筒状織布Ａにモルタルが完全に充填されれば、注入口から注入ホースが取り除かれて注入作業は完了する。この場合、注入口の逆止弁（図示省略）により、注入されたモルタルは袋体から流出することがない。 Moreover, as shown in the figure, the holes 4 leading from the inside of the tubular woven fabric B to the inside of the tubular woven fabric A are provided at two locations on the side surface of the tubular woven fabric B facing the inside of the tubular woven fabric A, The dimension is 50 mm in diameter. The fluid material injection port provided at one end of the tubular woven fabric B may be a commonly used one provided with a check valve.
The ends of the tubular woven fabrics A and B are folded back and closed by sewing. In this state, for example, mortar is filled as a fluid material from the injection port by a mortar pump and an injection hose. The injected mortar is filled into the tubular woven fabric B, and when the mortar exceeds the crossing portion, the mortar enters the tubular woven fabric A through the hole 4 that leads from the inside of the tubular woven fabric B to the inside of the tubular woven fabric A. Also begins to fill.
Therefore, at the intersection, the tubular woven fabric A is filled with mortar while the tubular woven fabric B is kept in a sufficiently swollen state. If the cylindrical woven fabric A is completely filled with mortar, the injection hose is removed from the injection port and the injection operation is completed. In this case, the injected mortar does not flow out of the bag due to the check valve (not shown) at the inlet.

筒状織布Ａ、Ｂとも実施例３と同じであるが、図４に示すように、筒状織布Ａの大径部２には相対する位置に２箇所、開口部３としてスリットの代わりに長さ１５０ｍｍの孔が設けられており、筒状織布Ｂがそこを貫通して筒状織布Ａの大径部２内部に筒状織布Ｂの大径部２が介装されるように組み立てられている。
前記孔は、筒状織布Ｂの直径に略等しい円形の孔であり、筒状織布Ｂがモルタル等の流動性材料の充填により膨らんで断面が略円形になった場合に、該孔と筒状織布Ｂの外面とがフィットするようになっている。
筒状織布Ａの孔と筒状織布Ｂとの接合部の加工は実施例３と同様であるが、接合部において互いの織布が膨らんだ状態でフィットするため、より強度の高い接合構造が得られる。 Both the tubular woven fabrics A and B are the same as those in the third embodiment. However, as shown in FIG. A hole having a length of 150 mm is provided in the tube, and the tubular woven fabric B passes through the hole, and the large-diameter portion 2 of the tubular woven fabric B is interposed inside the large-diameter portion 2 of the tubular woven fabric A. Assemble.
The hole is a circular hole substantially equal to the diameter of the tubular woven fabric B. When the tubular woven fabric B is swollen by filling with a fluid material such as mortar and has a substantially circular cross section, The outer surface of the tubular woven fabric B fits.
Processing of the joint portion between the hole of the tubular woven fabric A and the tubular woven fabric B is the same as that of the third embodiment. A structure is obtained.

かくして、本第３、第４各実施例の土木構造物形成用袋体は、筒状部１と該筒状部１の直径よりも大きな大径部２を有する筒状織布Ａの大径部２に、一対以上の相対抗する開口部３を設け、その開口部３に他の筒状織布Ｂを挿入して貫通させ、筒状織布Ａの開口部３と他の筒状織布Ｂとを接合し、筒状織布Ａと筒状織布Ｂの交差部において、他の筒状織布Ｂに筒状織布Ａ内部に連通する孔４を設け、さらに、他の筒状織布Ｂに流動性材料の注入口を設けることから、第１、第２各実施例の土木構造物形成用袋体と同様に接合部強度が安定し、括れが発生しない。
また、交差部において筒状織布Ｂが筒状織布Ａを貫通しているため、袋体の内部にモルタル等が充填されて構造体となった場合、固化したモルタル等は袋体で拘束されるので曲げ耐力において有利になり、例えば、曲げ荷重が加わり、筒状織布Ａ、Ｂの下面に引張り応力が発生するようなケースでは、あらかじめ筒状織布の下面側において、長さ方向に高強度低伸度性繊維を織り込んでおくと、構造体としての曲げ耐力が向上するが、これはこの種の筒状織布が貫通して袋体を形成している場合においてより有効に作用する。
そして、施工場所へ、袋体をコンパクトにたたんで持ち込むことができ、さらに、袋体は軽量であるため運搬に重機を必要とせず、現場立地条件が悪い場合でも施工が容易になる。 Thus, the civil engineering structure forming bag of each of the third and fourth embodiments has the large diameter of the tubular woven fabric A having the tubular portion 1 and the large diameter portion 2 larger than the diameter of the tubular portion 1. The part 2 is provided with a pair or more of opposing openings 3, and another cylindrical woven fabric B is inserted through the opening 3 so as to pass therethrough. The cloth B is joined, and at the intersection of the tubular woven cloth A and the tubular woven cloth B, the other tubular woven cloth B is provided with a hole 4 communicating with the inside of the tubular woven cloth A. Since the flowable material injection port is provided in the woven fabric B, the joint strength is stable and no constriction occurs as in the case of the civil engineering structure forming bags of the first and second embodiments.
Further, since the tubular woven fabric B penetrates the tubular woven fabric A at the intersection, when the inside of the bag body is filled with mortar or the like to form a structure, the solidified mortar is restrained by the bag body. Therefore, in the case where a bending load is applied and a tensile stress is generated on the lower surfaces of the tubular woven fabrics A and B, for example, in the length direction on the lower surface side of the tubular woven fabric in advance. When weaving high-strength low-stretch fibers into the fabric, the bending strength of the structure is improved, but this is more effective when this type of tubular woven fabric penetrates to form a bag. Works.
The bag can be folded compactly and brought into the construction site. Further, since the bag is lightweight, no heavy equipment is required for transportation, and the construction is easy even when the site location conditions are poor.

図５〜図６に示すように、実施例３又は実施例４の袋体を１パターンとして、連続的にこのパターンがつながっており、袋体の一端に流動性材料の注入口５をつけた連続十字構造形成用袋体及び格子構造形成袋体は以下のようになる。
すなわち、図５に示すように、注入口５を設けた筒状織布Ｂ１が縦方向に延び、横方向に延びる複数本の筒状織布Ａ１内部を貫通して連続十字構造形成用袋体を形成する。
さらに、図６に示すように、貫通された複数本の筒状織布Ａ１が、前記筒状織布Ｂ１と並行に配列された複数本の筒状織布Ａ２内部を貫通することで格子構造形成用袋体が形成される。
なお、注入口５を複数個所に設ける場合は、前記連続十字構造形成用袋体では縦方向に延びる筒状織布Ｂ１の適当な個所に取り付ける。格子構造形成用袋体では、横方向に延びた筒状織布Ａ１端部同士がつながった形でパターンが繰り返される。
このように構成すると、流動性材料は、図７に示すように、筒状織布Ｂ１の一端から次第に充填されていき、筒状織布Ａ１と筒状織布Ｂ１の交差部を超えた時点で筒状織布Ｂ１内部から筒状織布Ａ１内部に通じる孔４を通して筒状織布Ａ１にも充填され始める。充填された流動性材料が筒状織布Ａ１と筒状織布Ａ２の交差部を超えると、同様に、筒状織布Ａ１内部から筒状織布Ａ２内部へ充填される。このとき、筒状織布Ａ１が十分膨らんだ状態が保たれつつ筒状織布Ａ２に流動性材料が充填されていく。 As shown in FIG. 5 to FIG. 6, the bag body of Example 3 or Example 4 is taken as one pattern, and this pattern is continuously connected, and an inlet 5 of a fluid material is attached to one end of the bag body. The continuous cross structure forming bag and the lattice structure forming bag are as follows.
That is, as shown in FIG. 5, the tubular woven fabric B1 provided with the injection port 5 extends in the longitudinal direction and penetrates through the inside of the plurality of tubular woven fabrics A1 extending in the lateral direction. Form.
Furthermore, as shown in FIG. 6, a plurality of penetrated tubular woven fabrics A1 penetrates the inside of the plurality of tubular woven fabrics A2 arranged in parallel with the tubular woven fabric B1, thereby forming a lattice structure. A forming bag is formed.
In addition, when providing the injection port 5 in several places, it attaches to the appropriate location of the cylindrical woven fabric B1 extended in the vertical direction in the said continuous cross structure formation bag body. In the lattice structure forming bag, the pattern is repeated in such a manner that the ends of the tubular woven fabric A1 extending in the lateral direction are connected to each other.
If comprised in this way, as shown in FIG. 7, fluid material will be gradually filled from the end of cylindrical woven fabric B1, and the time of exceeding the cross | intersection part of cylindrical woven fabric A1 and cylindrical woven fabric B1. Thus, the tubular woven fabric A1 starts to be filled through the hole 4 that communicates from the inside of the tubular woven fabric B1 to the inside of the tubular woven fabric A1. When the filled flowable material exceeds the intersection of the tubular woven fabric A1 and the tubular woven fabric A2, it is similarly filled from the tubular woven fabric A1 into the tubular woven fabric A2. At this time, the tubular woven fabric A2 is filled with the fluid material while the tubular woven fabric A1 is kept in a sufficiently swollen state.

図８に示すように、筒状織布Ａ、Ｂ、Ｃを組み合わせて大径部２から筒状部１が放射状に分岐する構造の袋体を形成するには、図９に示すような手順で行う。
すなわち、筒状織布Ａにあらかじめ複数の何対かの相対抗する開口部３を設けておき、複数の袋体を組み合わせた状態で互いの開口部３の位置が略一致するよう、他の筒状織布Ｂ、Ｃの大径部２にも複数の相対抗する開口部３を設けておく。
次に、筒状織布Ａの開口部３に筒状織布Ｂを貫通させて織布Ｂの大径部２をはめ込み、開口部３の位置合わせをした後、さらに筒状織布Ｃの大径部２がはまり込むように組み合わせる。そして、互いの開口部３を位置合わせすれば組み立ては完了である。
なお、ここでは、全て筒状織布を貫通させる例で示したが、この貫通タイプよりはモルタル注入時及び構造体になった場合の強度では劣るものの、実施例１又は実施例２に示したような筒状織布の端部を大径部２に接合する方式を使用することもできる。 As shown in FIG. 8, in order to form a bag having a structure in which the cylindrical portion 1 branches radially from the large diameter portion 2 by combining the cylindrical woven fabrics A, B, and C, the procedure as shown in FIG. To do.
That is, a plurality of pairs of opposed openings 3 are provided in the tubular woven fabric A in advance, and the positions of the openings 3 are substantially matched with each other in a state where the plurality of bags are combined. A plurality of opposed openings 3 are also provided in the large-diameter portion 2 of the cylindrical woven fabrics B and C.
Next, after the tubular woven fabric B is passed through the opening 3 of the tubular woven fabric A and the large-diameter portion 2 of the woven fabric B is fitted and the opening 3 is aligned, the tubular woven fabric C is further aligned. Combine so that the large diameter part 2 fits. And if mutual opening part 3 is aligned, an assembly is completion.
In addition, although it showed by the example which penetrates all cylindrical woven fabrics here, although it was inferior to this penetration type at the time of mortar injection | pouring and when it became a structure, it showed in Example 1 or Example 2. A method of joining the end portion of the cylindrical woven fabric to the large diameter portion 2 can also be used.

このような第５、第６各実施例の土木構造物形成用袋体は、図５に示すように、注入口５を設けた筒状織布Ｂ１が縦方向に延び、横方向に延びる複数本の筒状織布Ａ１内部を貫通して連続十字構造形成用袋体を形成している場合、注入された流動性材料は、筒状織布Ｂ１内部に充填され、筒状織布Ａ１との交差部において、下方から順次、貫通部を通して筒状織布Ａ１内部に充填されていく。
また、図６に示すように、前記貫通された複数本の筒状織布Ａ１が、前記筒状織布Ｂ１と並行に縦方向に延びた複数本の筒状織布Ａ２内部を貫通して格子構造形成用袋体が形成されている場合、注入された流動性材料は筒状織布Ｂ１内部に充填され、筒状織布Ａ１との交差部において下方から順次貫通部を通して筒状織布Ａ１内部に充填され、さらに筒状織布Ａ１と交差する筒状織布Ａ２内部に、筒状織布Ｂ１に近い交差部から順次充填されていく。 As shown in FIG. 5, such a civil engineering structure forming bag body of each of the fifth and sixth embodiments has a plurality of tubular woven fabrics B <b> 1 provided with injection ports 5 extending in the vertical direction and extending in the horizontal direction. When the continuous cross structure forming bag is formed through the inside of the cylindrical woven fabric A1, the injected fluid material is filled into the cylindrical woven fabric B1, and the cylindrical woven fabric A1 and In the crossing portion, the cylindrical woven fabric A1 is filled through the penetration portion sequentially from below.
Further, as shown in FIG. 6, the plurality of penetrated tubular woven fabrics A1 penetrate through the inside of the plurality of tubular woven fabrics A2 extending in the vertical direction in parallel with the tubular woven fabric B1. When the lattice structure forming bag is formed, the injected flowable material is filled into the tubular woven fabric B1, and the tubular woven fabric passes through the through portion sequentially from below at the intersection with the tubular woven fabric A1. The inside of the tubular woven fabric A2 that fills the inside of the A1 and further intersects with the tubular woven fabric A1 is sequentially filled from the intersection near the tubular woven fabric B1.

また、図９に示すように組み立てられた袋体の、筒状織布Ｃに流動性材料として流動固化材を充填すれば、大径部２を通じて筒状織布Ａ及び筒状織布Ｂ内へも流動固化材が充填されていき、流動固化材が固化すると立体的な十字構造物、格子構造物が形成されることになる。   If the fluidized solidifying material is filled in the tubular woven cloth C of the bag body assembled as shown in FIG. 9 as a fluid material, the inside of the tubular woven cloth A and the tubular woven cloth B through the large diameter portion 2. The fluidized solidifying material is also filled into the surface, and when the fluidized solidified material is solidified, a three-dimensional cross structure and lattice structure are formed.

一方、この第５、第６各実施例の交差・連続十字・格子構造体は、下記のような用途に応用することができる。
斜面安定工法としての受圧板として用いる場合は、筒状織布Ａ、Ｂの貫通する個所にアンカー定着具を設け内部をモルタルで充填し、十字形状の袋体を受圧板用袋体として使用する。一体に成形された十字構造の受圧板は、表面が袋で強化されたコンクリート構造物となり、グランドアンカーの斜面への定着のための反力構造物として有効に機能する。
斜面や軟弱地盤などの地盤の補強に用いると、地盤の変形を抑制・抑止することができる。斜面に剛性のある格子構造体をアンカーで定着すると、斜面表面の移動土塊の崩れを抑制・抑止することができる。軟弱地盤では剛性のある格子構造体自体が地盤表層の補強となり局所的な不等沈下を抑制することができる。
また、海底にある消波ブロックやコンクリートブロックによる人工磯が波浪の影響を受けて倒壊したり沖へ移動したり陸地へ押し戻されたりするのを防ぐために、格子構造体をその上に覆い被さるように設置して安定を図るという使い方ができる。
以上の場合は、筒状織布内部に充填するものは、モルタルのような流動固化材であってもよく、また、流動化土のような土であってもよい。 On the other hand, the intersecting / continuous cross / lattice structures of the fifth and sixth embodiments can be applied to the following applications.
When used as a pressure receiving plate as a slope stabilization method, an anchor fixing tool is provided at a location where the cylindrical woven fabrics A and B penetrate, and the interior is filled with mortar, and a cross-shaped bag body is used as the pressure receiving plate bag body. . The integrally formed cross-shaped pressure receiving plate becomes a concrete structure whose surface is reinforced with a bag, and effectively functions as a reaction force structure for fixing to the slope of the ground anchor.
When used for reinforcement of ground such as slopes and soft ground, deformation of the ground can be suppressed / suppressed. If a rigid lattice structure is fixed to the slope with anchors, it is possible to suppress / suppress the collapse of the moving soil mass on the slope surface. In soft ground, the rigid lattice structure itself reinforces the ground surface layer and local uneven settlement can be suppressed.
In addition, to prevent the artificial dams from wave-dissipating blocks and concrete blocks on the sea floor from collapsing, moving offshore, or being pushed back to the land under the influence of waves, cover the lattice structure on it. It can be used for stability by installing it in
In the above case, what is filled in the cylindrical woven fabric may be a fluidized solid material such as mortar, or may be a soil such as fluidized soil.

海底では、砂の移動により藻場の造成等で埋没や洗掘といった問題が発生するが、高さが１０ｃｍ程度になる格子構造体を海底に設置しておけばそれが障害となって砂の移動が妨げられ、前記の問題を解決することができる。このような用途にも格子構造体が使用できる。
軟弱地盤では上部に大型の構造物が建築される場合、地盤自体の補強が重要になるが、格子構造体を地中に何段にも重ねて埋設しておけば強固に地盤を補強する基礎とすることができる。 At the bottom of the sea, the movement of sand causes problems such as burial and scouring due to the formation of algae beds. However, if a lattice structure with a height of about 10 cm is installed on the sea floor, it becomes an obstacle and the sand The movement is hindered and the above problem can be solved. A lattice structure can also be used for such applications.
When a large structure is built on the soft ground, it is important to reinforce the ground itself. However, if the grid structure is buried in layers in the ground, the foundation will be firmly reinforced. It can be.

また、図８に示すように、立体的に十字構造に筒状織布を組んだものは、金型が不要で、現場で容易に施工できるので、表面が繊維で強化された、風化しにくい図１０に示すような消波ブロック構造物として利用することができる。
土砂崩れが発生するような場所では、砂防堰堤が設けられているが、同図に示すような立体的な格子構造体を作れば安価なモルタルで簡単な施工により適度な透過性と衝撃エネルギーの吸収能力を有する砂防堰堤が形成される。
立体的に格子構造を組んだものは、地中の地盤補強や海底での人工漁礁として、また、海岸の消波構造物として利用できるばかりでなく、立体的なコンクリートの布型枠として、さらに繊維で表面が強化されたコンクリート構造物として、一般的な建築分野等でも利用することが可能である。 In addition, as shown in FIG. 8, a three-dimensional cross structure with a tubular woven fabric does not require a mold and can be easily constructed on site, so the surface is reinforced with fibers and is not easily weathered. It can be used as a wave-dissipating block structure as shown in FIG.
In places where landslides occur, sabo dams are provided, but if a three-dimensional lattice structure as shown in the figure is created, moderate permeability and impact energy absorption can be achieved by simple construction with inexpensive mortar. Sabo dam with capacity is formed.
The three-dimensional lattice structure can be used not only for ground reinforcement in the ground, artificial reefs on the seabed, and as a wave-absorbing structure on the coast, but also as a three-dimensional concrete cloth formwork. As a concrete structure whose surface is reinforced with fibers, it can be used in general construction fields.

以上、本発明の複数の実施例を、モルタルのような流動性材料が固化する事例で説明したが、補強用の構造体として大きな耐力が必要でない場合は、土砂が流動しやすい状態に調整された流動化土のように、時間が経過しても固化しないものを流動性材料として使用してもよい。このときは、交差部の内部構造が簡単な、図１に示すような非貫通タイプが好ましい。モルタルを注入する場合と異なり、構造体として大きな耐力を期待しなくてよいので、非貫通タイプで交差部の強度も十分である。
また、以上の説明では固体粒子を含む流動性材料で説明したが、空気や水のような流動性材料を筒状織布に注入することも可能であり、この場合は、各筒状織布に気密性又は水密性のライニング加工を施しておけばよい。あるいは、気密性又は水密性を有する薄いチューブを各筒状織布に挿入して各チューブに流動性材料を個別に送り込んで筒状織布を膨らませてもよい。 As described above, a plurality of embodiments of the present invention have been described by using a case where a fluid material such as mortar is solidified. A fluidized material that does not solidify over time, such as fluidized soil, may be used. In this case, the non-penetrating type as shown in FIG. Unlike the case of injecting mortar, it is not necessary to expect a large yield strength as a structure, so that the strength of the crossing portion is sufficient with the non-penetrating type.
In the above description, the flowable material containing solid particles has been described. However, it is also possible to inject a flowable material such as air or water into the tubular woven fabric. Air-tight or water-tight lining may be applied to the. Alternatively, a thin tube having airtightness or watertightness may be inserted into each tubular woven fabric, and a flowable material may be individually fed into each tube to inflate the tubular woven fabric.
