Description

本発明は、植生法枠の構築方法に関するものである。   The present invention relates to a method for constructing a vegetation frame.

これまでの法枠工はモルタルやコンクリート吹付工による造成であった。
特開平１０−２９８９９９号公報。 So far, the frame work has been mortar and concrete spraying.
Japanese Patent Laid-Open No. 10-298999.

前記した従来の法枠工の構築方法にあっては、次のような問題点がある。
＜１＞ たとえ格子状に配置された法枠であってもその枠内に施された植生が十分に生育するまではセメント色の目立つ法枠が残るものであった。
＜２＞ また、モルタルやコンクリート吹付工による法枠は、経年するにつれて構造的に劣化が進むことは避けられず、さらに強度は低下することになるため、供用後の維持管理が問題となっている。
＜３＞ また、コンクリート法枠と枠内に緑化工を行う方法は、その施工において法枠の造成が先行するが、吹付作業ではコンクリートが緑化部分にも飛び散るためにその部分が硬化すると植物の生育ができない。
＜４＞ そのため、従来の施工ではあらかじめ枠内にブルーシート等の養生シートを枠毎に設けており、その張る手間と材料費、さらにブルーシートは転用できないので廃棄処分されていた。
＜５＞ 連続長繊維を用いた砂基材を厚く吹き付て造成する補強土工法では、内部に多孔帯状体等が含まれていないために補強効果をもたらすには全面的に厚い層を造成しなければならず、大量の砂基材が必要となり、施工性、コスト面で課題があった。
＜６＞ あらかじめ法面に挿入された棒材に対して、多孔帯状体に棒材挿通部位を設けて、棒材を挿通させ、その状態から押し込み部材を棒材頭部に取り付けて多孔帯状体をのり面に押し込む方法では、のり面の凹凸や岩部とのこすれ等による多孔帯状体に損傷が生じやすい。また、平面的な法面であれば、棒材の押し込み力によって法面に密着するが、凹凸状の法面で多孔帯状体を法面に密着させるには、凹凸面の変化のある個所に棒材をあらかじめ挿入して多孔帯状体を法面に押し込まなければならない。こうした点から、施工性、コスト面、さらに多孔帯状体の損傷による安定性に課題があった。
The above-described conventional method for constructing a frame work has the following problems.
<1> Even if the frame is arranged in a lattice pattern, the frame with a conspicuous cement color remains until the vegetation applied in the frame grows sufficiently.
<2> In addition, the legal framework by mortar and concrete spraying work is unavoidably structurally deteriorated over time, and the strength will be further reduced, so maintenance after use becomes a problem. Yes.
<3> In addition, the concrete frame and the method of revegetation in the frame are preceded by the construction of the frame in the construction. I can't grow.
<4> Therefore, in conventional construction, a curing sheet such as a blue sheet is provided for each frame in advance in the frame, and the labor and material cost for the extension, and further, the blue sheet cannot be diverted and are discarded.
<5> In the reinforced earth construction method, in which a sand base material using continuous long fibers is sprayed thickly, a porous layer is not included in the interior, so that a thick layer is formed entirely to bring about a reinforcing effect. A large amount of sand base material is required, and there are problems in terms of workability and cost.
<6> With respect to the bar inserted in advance on the slope, a bar insertion part is provided in the porous band, the bar is inserted, and the pushing member is attached to the bar head from that state, and the porous band In the method of pushing the material into the slope, damage to the porous strip due to unevenness of the slope or rubbing with the rock is likely to occur. In addition, in the case of a flat slope, it is brought into close contact with the slope by the pushing force of the rod, but in order to make the porous strip closely contact with the slope with the uneven slope, it is necessary to change the uneven face. A rod must be inserted in advance and the porous strip must be pushed into the slope. From these points, there were problems in workability, cost, and stability due to damage to the porous strip.

上記のような課題を解決するために、本発明の植生法枠の構築方法は、多数の貫通孔を表面から裏面まで貫通させた材料であり、その貫通孔を通して植物の根が法面に向けて侵入することを許容する多孔帯状体を使用し、この多孔帯状体を、隣接する多孔帯状体との間隔を空けて法面に敷設し、露出した法面を残して、多孔帯状体の上に、砂と繊維とセメントと水を混合した砂基材を吹き付けて構築する植生法枠の構築方法を特徴とするものである。
また本発明の植生法枠の構築方法は、多数の貫通孔を表面から裏面まで貫通させた材料であり、その貫通孔を通して植物の根が法面に向けて侵入することを許容する多孔帯状体を使用し、この多孔帯状体を、法面と離れた状態で、かつ、隣接する多孔帯状体との間隔を空けて法面に敷設し、露出した法面を残して、多孔帯状体の上に、砂と繊維とセメントと水を混合した砂基材を吹き付けて構築する、植生法枠の構築方法を特徴としたものである。
また本発明の植生法枠の構築方法は、多数の貫通孔を表面から裏面まで貫通させた材料であり、その貫通孔を通して植物の根が法面に向けて侵入することを許容する多孔帯状体を、法面に縦横に敷設し、露出した法面を残して、多孔帯状体の上に、砂と繊維とセメントと水を混合した砂基材を吹き付けることによって、井桁状に植生した法枠を構築する植生法枠の構築方法を特徴としたものである。 In order to solve the above problems, a method for constructing vegetation method frame of the present invention, a large number of through-holes Ri material der obtained by penetrating from the surface to the back surface, the roots slopes of the plant through the through hole Use a porous strip that allows intrusion toward the surface, lay this porous strip on the slope with a gap between adjacent porous strips, leaving an exposed slope, It is characterized by a construction method of a vegetation frame that is constructed by spraying a sand base material mixed with sand, fibers, cement, and water.
The construction method of vegetation method frame of the present invention, Ri numerous materials der which the through hole is penetrated from the surface to the back surface, the porous strip that allows the plant roots through the through hole penetrating toward the slopes The porous band-shaped body is laid on the slope in a state separated from the slope and spaced from the adjacent porous strip, leaving an exposed slope, It is characterized by the construction method of the vegetation method frame, which is constructed by spraying a sand base material mixed with sand, fibers, cement and water.
The vegetation method frame construction method of the present invention is a material in which a large number of through-holes are penetrated from the front surface to the back surface, and a porous band-like body that allows a plant root to enter the slope through the through-holes. The frame is vegetated in a grid pattern by spraying a sand base mixed with sand, fibers, cement, and water on the porous strip, leaving the exposed slopes laid vertically and horizontally. It is characterized by the construction method of the vegetation frame that constructs .

本発明の植生法枠の構築方法は以上説明したようになるから次のような効果を得ることができる。
＜１＞ 本発明の法枠は、多孔帯状体を内在した植物の生育が可能となる砂基材を用いた法枠構造であるため、全面的な緑化が初期の施工段階から可能となる。
＜２＞ さらに、多孔帯状体の敷設された個所に厚い砂基材が吹き付けられることになるため、全面的に厚く砂基材を吹き付けることが避けられるため、施工性、コスト面で優れる。
＜３＞ また植物の生育状況に従い、根茎の緊縛力が大きくなることが期待できるため、経年後の法枠はさらに傾斜面の安定性を向上することが期待できる。
＜４＞ 公知のモルタルやコンクリート吹付工による法枠では養生期間が必要となるが、本発明の方法であれば、あらかじめ製品加工された多孔帯状体を法面上に配置するから、初期段階で法面の崩壊等を抑制する補強効果があり、初期の段階での高い安全性を確保できる。
＜５＞ あるいは本発明の方法であれば、あらかじめ製品加工された多孔帯状体を法面と離れて配置し、その離れ間に砂基材を吹付け充填して構成する法枠であることから、多孔帯状体が初期段階で法面の崩壊等を抑制する補強効果があるため、高い安全性を確保できる。
Since the vegetation frame construction method of the present invention is as described above, the following effects can be obtained.
<1> Since the method frame of the present invention is a method frame structure using a sand base material that enables the growth of a plant having a porous band-like body, full greening is possible from the initial construction stage.
<2> Furthermore, since a thick sand base material is sprayed on the place where the porous band-like body is laid, it is possible to avoid spraying the sand base material over the entire surface.
<3> Moreover, since the binding power of the rhizome can be expected to increase in accordance with the growth state of the plant, the legal frame after aging can be expected to further improve the stability of the inclined surface.
<4> Although a curing period is required in a method frame using a known mortar or concrete sprayer, a porous strip that has been processed in advance is placed on the slope in the method of the present invention. There is a reinforcing effect that suppresses the collapse of the slope, and high safety can be secured in the initial stage.
<5> Or if it is the method of this invention, it is the method frame which arrange | positions the porous strip shaped product processed beforehand away from a slope, and sprays and fills a sand base material in the space | interval. In addition, since the porous strip has a reinforcing effect for suppressing the collapse of the slope at the initial stage, high safety can be ensured.

以下図面を参照にしながら本発明の好適な実施の形態を詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

＜１＞全体の構成。
本発明の構築方法は、多孔帯状体１を使用し、これを間隔を空けて法面に敷設し、その多孔帯状体１の上に砂基材２を吹き付ける方法、あるいはその上にさらに植生基盤材３を吹き付ける方法である。
以下、構成する材料と構築方法を説明する。 <1> Overall configuration.
The construction method of the present invention uses a porous strip 1, lays it on a slope at an interval, and sprays a sand substrate 2 on the porous strip 1, or a vegetation base further on it. This is a method of spraying the material 3.
Hereinafter, constituent materials and construction methods will be described.

＜２＞多孔帯状体１。
本発明の構築方法で使用する多孔帯状体１は、多数の貫通孔を表面から裏面まで貫通させた材料を帯状に形成した資材である。
多数の貫通孔を表面から裏面まで貫通させた材料として、例えば合成繊維、ガラス繊維、アラミド繊維、炭素繊維を樹脂に含侵させグリッド状に一体整形した線材１１を格子状に結合した資材を使用する。
図４の実施例に示す多孔帯状体１は、線材１１を多少の間隔を介して格子状に結合した材料であるから、線材１１と線材１１の間には多くの孔１２が開口しており、その孔１２を通して植物の根が法面に向けて侵入することを許容することになる。
多孔帯状体１としては多数の貫通孔を表面から裏面まで貫通させた材料であればよいから、必ずしも格子状ではなく、例えば合成繊維を「たわし」のようにループ状に絡ませた資材を使用することもできる。
この材料の場合にも、繊維と繊維の間には多くの孔１２が介在しており、その孔１２を通して植物の根が法面に向けて侵入することを許容する。
その他、多孔質の資材であれば、市販のものを帯状に切断して使用することができる。 <2> Porous strip 1.
The porous strip 1 used in the construction method of the present invention is a material in which a material in which a large number of through holes are penetrated from the front surface to the back surface is formed in a strip shape.
As a material in which a large number of through-holes are penetrated from the front surface to the back surface, for example, a material in which a synthetic material, glass fiber, aramid fiber, carbon fiber is impregnated with a resin and the wire 11 integrally formed in a grid shape is combined in a grid shape To do.
Since the porous strip 1 shown in the embodiment of FIG. 4 is a material in which the wires 11 are joined in a lattice pattern with some spacing, many holes 12 are opened between the wires 11 and 11. The roots of the plants are allowed to enter the slope through the holes 12.
Since the porous strip 1 may be a material having a large number of through holes penetrating from the front surface to the back surface, it is not necessarily a lattice shape, and for example, a material in which synthetic fibers are entangled in a loop shape like “scouring” is used. You can also
Also in this material, many holes 12 are interposed between the fibers, and the roots of the plants are allowed to enter the slope through the holes 12.
In addition, if it is a porous material, a commercially available thing can be cut | disconnected and used for a strip | belt shape.

＜３＞多孔帯状体の敷設。（図１）
上記した多孔帯状体１を使用し、複数本の多孔帯状体１を、隣接する多孔帯状体１との間に間隔を空けて法面４の上に直接、敷設する。
その場合に多孔帯状体１を、法面４に縦方向（上から下へ）と横断（水平方向）方向に交差させて敷設すれば、法面４の表面に井桁状の法枠を形成することができる。
ただし、井桁状、格子状ではなく、菱形状、あるいは縦、横いずれかを一方向に向けて敷設することももちろん可能である。
敷設したら、要部にアンカーを打ち込んで多孔帯状体１の法面上での移動を阻止する。
なお、図１の実施例では多孔帯状体１を直接法面の上に敷設した場合を説明したが、図３に示すように多孔帯状体１と法面との間にスペーサ５を介在させて、中空に浮かせた状態で敷設することも可能である。 <3> Laying of a porous strip. (Figure 1)
Using the porous band-like body 1 described above, a plurality of porous band-like bodies 1 are directly laid on the slope 4 with a space between adjacent porous band-like bodies 1.
In that case, if the porous strip 1 is laid across the slope 4 in the vertical direction (from top to bottom) and in the transverse (horizontal direction), a cross-shaped frame is formed on the surface of the slope 4. be able to.
However, it is of course possible to lay the rhombus shape or either the vertical or horizontal direction in one direction instead of the grid pattern or grid shape.
After laying, an anchor is driven into the main part to prevent the movement of the porous band 1 on the slope.
In the embodiment of FIG. 1, the case where the porous strip 1 is directly laid on the slope has been described. However, as shown in FIG. 3, a spacer 5 is interposed between the porous strip 1 and the slope. It is also possible to lay in a state of floating in the hollow.

＜４＞砂基材２の吹き付け。
多孔帯状体１を法面４上に敷設したら、露出した法面４を残して、多孔帯状体１の上に砂基材２を吹き付ける。
砂基材２は、例えば砂と繊維とセメントと水を混合したような公知の材料を使用する。
混合する繊維は、短繊維でも長繊維でもよい。
この砂基材２を攪拌し、コンプレッサで圧縮した空気によって、法面４に敷設した多孔帯状体１の上から、その内部の孔１２に侵入するよう、多孔帯状体１上部から砂基材２を吹き付ける。
さらに多孔帯状体１の周囲にも多孔帯状体１を巻き込むように砂基材２を吹き付ける。
砂基材２の吹き付けに際しては、露出した法面４を残して、多孔帯状体１の上を対象に吹き付けるが、多孔帯状体１の周囲、すなわち露出した法面４上に飛散することは避けられない。
しかし砂基材２は植物の生育を阻害するものでなく、植生が可能な材料であるため、たとえ露出した法面４上に飛散して残ったとしても問題はない。
したがって従来のように、法枠で囲まれた内部にブルーシートを敷設して吹き付け材の飛散を阻止するというような枠内処理の作業は必要ない。
以上の施行の結果、多孔帯状体１に砂基材２の繊維が絡むことになり、大きな補強機能が得られる。
また多孔帯状体１に吹き付けた砂基材２は多孔帯状体１の孔１２を通過して強制的に充填されるから、法面４の凹凸によって、多孔帯状体１が法面４から離れていても、法面４に密着した法枠が形成される。
同様の理由で、図３の実施例のように多孔帯状体１と法面との間にスペーサ５を介在させた場合でも、多孔帯状体１の下に完全に砂基材２を充填することができる。 <4> Spraying of the sand base 2.
When the porous strip 1 is laid on the slope 4, the sand base 2 is sprayed on the porous strip 1 leaving the exposed slope 4.
For the sand base 2, a known material such as a mixture of sand, fiber, cement and water is used.
The fibers to be mixed may be short fibers or long fibers.
The sand base material 2 is agitated from the upper part of the porous strip 1 so as to enter the holes 12 inside the porous strip 1 laid on the slope 4 with the air compressed by the compressor. Spray.
Furthermore, the sand base material 2 is sprayed so that the porous strip 1 is wound around the porous strip 1.
When the sand base material 2 is sprayed, the exposed slope 4 is left and the surface of the porous strip 1 is sprayed on the object, but it is avoided to scatter around the porous strip 1, that is, on the exposed slope 4. I can't.
However, since the sand base material 2 does not inhibit the growth of the plant and is a material that can be vegetated, there is no problem even if it remains scattered on the exposed slope 4.
Therefore, unlike the prior art, there is no need for an in-frame processing operation such as laying a blue sheet inside the legal frame to prevent the spray material from scattering.
As a result of the above enforcement, the fibers of the sand base material 2 are entangled with the porous strip 1 and a large reinforcing function is obtained.
Moreover, since the sand base material 2 sprayed on the porous strip 1 passes through the holes 12 of the porous strip 1 and is forcibly filled, the porous strip 1 is separated from the slope 4 by the unevenness of the slope 4. Even so, a method frame in close contact with the slope 4 is formed.
For the same reason, even when the spacer 5 is interposed between the porous strip 1 and the slope as in the embodiment of FIG. 3, the sand base 2 is completely filled under the porous strip 1. Can do.

＜５＞砂基材２吹き付け後の法枠。
前記したように砂基材２にはセメントを混合してある。
しかし一般に砂基材２においてはセメント量はきわめてわずかであり、そのために砂基材２を吹き付けた法枠の部分がブロック状に強固に硬化してしまうことはなく、砂粒子間には十分な間隔が維持されている。
そのために、周囲から飛来した植物の種子は砂基材２に定着し、根の生育、根の法面４への侵入が可能である。
また、多孔帯状体１を敷設していない部分は、法面４が露出しているから、その露出面に周囲から飛来した植物の種子が定着して生育することは十分に可能である。
このように、砂基材２は法面４の全面に吹き付ける必要はなく、多孔帯状体１の上を中心に吹き付けを行い、他の法面４は露出させたままであるから、施工が迅速で経済的である。
また、多孔帯状体１に繊維を含んだ砂基材２を吹き付けるから、繊維が多孔帯状体１の孔１２に絡んで、初期の段階から法面４の表面の崩壊などを抑制する補強効果を期待することができる。
さらに時間とともに植物が成長すれば、根茎の緊縛力が大きくなることが期待できるため、経年後の法枠はさらに傾斜面の安定性が向上する。 <5> Leg frame after sand substrate 2 is sprayed.
As described above, cement is mixed in the sand base 2.
However, in general, the amount of cement in the sand base material 2 is very small. Therefore, the portion of the method frame sprayed with the sand base material 2 is not hardened in a block shape, and there is sufficient space between the sand particles. The interval is maintained.
Therefore, the seeds of the plants flying from the surroundings are fixed on the sand base 2 and can grow roots and enter the root slope 4.
Moreover, since the slope 4 is exposed in the part where the porous strip 1 is not laid, it is possible that the seeds of the plants flying from the surroundings are fixed and grown on the exposed surface.
Thus, it is not necessary to spray the sand base material 2 on the entire surface of the slope 4, and spraying is performed around the porous band 1, and the other slope 4 remains exposed, so that the construction is quick. Economical.
Moreover, since the sand base material 2 containing fibers is sprayed on the porous strip 1, the fibers are entangled with the holes 12 of the porous strip 1, and the reinforcing effect of suppressing the collapse of the surface of the slope 4 from the initial stage is achieved. You can expect.
Further, if the plant grows with time, it can be expected that the binding power of the rhizomes will increase, so that the stability of the inclined surface is further improved in the legal frame after aging.

＜６＞植生基盤材３の吹き付け。
以上の工程によっても、植生法枠を構築することができるが、気象条件や法面４の傾斜、雨量などを考慮して、より植生を容易にするためには、さらに植生基盤材３の吹き付けを行う場合がある。
すなわち、上記の工程で吹き付けた砂基材２の上、および露出した法面４の上に、植生基盤材３を吹き付ける。
植生基盤材３としては、植生基材、種子、肥料、接合材などを混合した公知のものを採用することができる。
この植生基盤材３を、攪拌し、コンプレッサで圧縮した空気によって、砂基材２の上、および砂基材２の吹き付けを行っていない露出した法面４の上に吹き付け、法枠を完成する。 <6> Spraying the vegetation base material 3.
The vegetation frame can also be constructed by the above process, but in order to make vegetation easier in consideration of weather conditions, slope of slope 4 and rainfall, etc., vegetation base material 3 is further sprayed. May do.
That is, the vegetation base material 3 is sprayed on the sand base material 2 sprayed in the above process and on the exposed slope 4.
As the vegetation base material 3, a known material in which a vegetation base material, seeds, fertilizer, a bonding material and the like are mixed can be used.
The vegetation base material 3 is sprayed onto the sand base material 2 and the exposed slope 4 where the sand base material 2 is not sprayed with air that has been stirred and compressed by a compressor to complete the frame. .

＜７＞他の実施例。
上記の実施例では多孔帯状体１を直接、法面４に敷設する工法であった。
しかし図４以下に示すように、多孔帯状体１と法面４との間にスペーサ５を介在させ、法面４と多孔帯状体１の間隔を空けて敷設する方法を採用することもできる。
すなわち、まず法面４に半円状の鋼棒や帯状板で構成したスペーサ５を、アンカーを法面４に打ち込んで固定する。
半円形状の鋼棒などに限らず、コ字状、Ｌ字状など鋼棒、帯状板をスペーサ５として使用することもできる。
このスペーサ５を、一定の狭い間隔を介して一列に配置する。
その後、スペーサ５群の上に、前記した多孔帯状体１を被せる。
すると多孔帯状体１は法面４の上に半円柱を形成して敷設される。
この半円柱状の多孔帯状体１の上から、その内部に充填できるように前記した砂基材２を吹き付ける。
スペーサ５によって多孔帯状体１が立体的な曲面形状となるので、この多孔帯状体１を覆い隠すように砂基材２を吹き付ければ、所定幅および所定高さを持つ法枠形状ができる。
多孔帯状体１は多数の孔１２を開口しているから、砂基材２はその内部に侵入して充填される。
スペーサ５の位置においても、スペーサ５の幅が広すぎることがなければ、その下部の空間に砂基材２を吹き込んで充填することができる。
砂基材２の上面には、必要に応じて前記した植生基盤材３を吹き付けて法枠の構築を完成する。
なお、多孔帯状体１に剛性があれば、あらかじめ曲面形状に形成した多孔帯状体１を使用しても同様の施工を行うことができる。 <7> Other embodiments.
In the above-described embodiment, the construction was such that the porous strip 1 was directly laid on the slope 4.
However, as shown in FIG. 4 and subsequent figures, it is also possible to employ a method in which a spacer 5 is interposed between the porous strip 1 and the slope 4 and the slope 4 and the porous strip 1 are spaced apart.
That is, first, a spacer 5 composed of a semicircular steel rod or a strip plate is fixed to the slope 4 by driving the anchor into the slope 4.
The spacer 5 is not limited to a semi-circular steel bar, but a steel bar such as a U-shape or an L-shape, or a strip-like plate can also be used.
The spacers 5 are arranged in a line at a constant narrow interval.
Thereafter, the porous strip 1 is placed on the spacer 5 group.
Then, the porous strip 1 is laid on the slope 4 by forming a semi-cylinder.
The above-mentioned sand base material 2 is sprayed from above the semi-cylindrical porous strip 1 so that the inside thereof can be filled.
Since the porous strip 1 has a three-dimensional curved surface shape by the spacer 5, if the sand substrate 2 is sprayed so as to cover the porous strip 1, a frame shape having a predetermined width and a predetermined height can be formed.
Since the porous strip 1 has a large number of holes 12, the sand base material 2 penetrates into the inside thereof and is filled.
Even at the position of the spacer 5, if the width of the spacer 5 is not too wide, the sand base material 2 can be blown and filled in the space below the spacer 5.
The above-mentioned vegetation base material 3 is sprayed on the top surface of the sand base material 2 as necessary to complete the construction of the frame.
In addition, if the porous strip 1 has rigidity, the same construction can be performed even if the porous strip 1 formed in a curved shape in advance is used.

＜８＞スペーサ５を配置する効果。
スペーサ５を配置する実施例の場合、多孔帯状体１が地山面に直接当らずにすむため、地山の岩や凹凸面でのこすれがなく、多孔帯状体１への傷や損傷の発生を防止できる。
また砂基材２が、半円柱状の多孔帯状体１の内部に吹き付けられることで、地山と砂基材２との密着性がより優れたものとなる。
のり面からの土圧や崩壊エネルギーが発生した場合、法枠においては、地山側の反対面、すなわち法枠の表面に引張り力が働く。
しかし法枠工の中にある多孔帯状体１の位置はスペーサ５により外側面付近になることで、多孔帯状体１の本来持つ引張り特性を十分に機能させることができる。
その結果、半円柱状の多孔帯状体１内の砂基材２の安定性が確保されることになり、法枠が安定することから、結果として地山の崩壊を防止することが出来る。 <8> The effect of arranging the spacer 5.
In the case of the embodiment in which the spacer 5 is disposed, since the porous strip 1 does not directly hit the ground surface, there is no rubbing on the rock or uneven surface of the natural ground, and scratches or damage to the porous belt body 1 occur. Can be prevented.
Moreover, the sand base 2 is sprayed inside the semi-cylindrical porous strip 1 so that the adhesion between the natural ground and the sand base 2 is further improved.
When earth pressure or collapse energy is generated from the slope, a tensile force acts on the opposite side of the ground, that is, the surface of the frame in the frame.
However, since the position of the porous strip 1 in the frame is near the outer surface by the spacer 5, the tensile properties inherent to the porous strip 1 can be sufficiently functioned.
As a result, the stability of the sand base material 2 in the semi-cylindrical porous strip 1 is ensured, and the frame is stabilized. As a result, the collapse of the natural ground can be prevented.

＜９＞交差部の構成。
スペーサ５を介在させる工法でも、多孔帯状体１は縦方向、横方向のいずれか一方向でも配置できるが、より確実な法枠での補強をおこなうために縦横の格子状に配置してもよい。
多孔帯状体１を井桁状、格子状に配置した場合には、交差部が発生する。
この交差部では上下となる縦横の多孔帯状体１を確実に結合できるように、スペーサ５の配置は交差部をさけて配置する。
そのために、多孔帯状体１は交差部では断面が矩形状態となり、交差部の間では断面が半円柱状態となる場合がある。
<9> Configuration of the intersection.
Even in the construction method in which the spacer 5 is interposed, the porous band-like body 1 can be arranged in any one of the vertical direction and the horizontal direction, but may be arranged in a vertical and horizontal grid pattern for reinforcement with a more reliable method frame. .
When the porous strips 1 are arranged in a grid pattern or a grid pattern, intersections occur.
The spacers 5 are arranged so as to avoid the intersecting portions so that the vertical and horizontal porous strips 1 that are upper and lower at the intersecting portions can be reliably bonded.
For this reason, the cross section of the porous strip 1 may be in a rectangular state at the intersection, and the cross section may be in a semi-cylindrical state between the intersections.
