Description

本発明は一般斜面、切土法面や軟質、硬質の岩盤斜面、或いはコンクリート覆工斜面など（以下これらを総称して「斜面」という）の崩落を防止する斜面の安定化工法に関するものである。
The present invention relates to a slope stabilization method for preventing collapse of a general slope, a cut slope, a soft, hard rock slope, or a concrete lining slope (hereinafter collectively referred to as “slope”). .

海岸線の近くの花崗岩などの岩盤斜面に面して道路や鉄道が通っている現場においては、岩盤斜面の崩壊崩落防止対策を講じる必要がある。
また海岸斜面の波浪侵食による海岸線の後退防止にも有効な対策を講じる必要がある。
これらの対策工のひとつとして、コンクリート吹付け工法が知られている。
この工法は斜面の保護範囲に亘って補強鉄筋の配筋工を行った後、所定のかぶり厚にモルタルやコンクリート（総称してコンクリートという）を吹付けて補強された硬質覆工層を形成し、硬質覆工層の強度で崩落や侵食を抑制する方法が提案されている。
It is necessary to take measures to prevent the collapse of the rock slope at the site where roads and railways pass through the slope of granite near the coastline.
It is also necessary to take effective measures to prevent coastal retreat due to wave erosion on the coastal slope.
A concrete spraying method is known as one of these countermeasures.
In this method, after reinforcing bars are arranged over the protection range of the slope, a mortar or concrete (collectively called concrete) is sprayed to a specified cover thickness to form a hard lining layer that is reinforced. A method for suppressing collapse and erosion with the strength of the hard lining layer has been proposed.

上記した従来の斜面の安定化技術には次のような問題点がある。
（１）通常の平らな鉄筋コンクリート構造物と異なり、配筋面となる自然状態の斜面には大小の凹凸がある。そのため、現場の凹凸に合わせて鉄筋の現地加工を強いられるだけでなく、足場の悪い斜面で重たい鉄筋を持ち上げて配筋しなければならず、鉄筋の設置に多くの労力と時間を要する。
（２）補強用の鉄筋が海岸特有の塩化物イオンにより腐食し易い問題がある。
この対策として防錆性能の高いエポキシ樹脂などの防錆被膜で覆った鉄筋も知られているが、鉄筋の曲げ加工時に防錆被膜の亀裂、剥離を生じて鉄筋腐食の不安が残る。
（３）吹付けコンクリートの付着性をよくするためにラス網が使用されるが、金属製のラス網も鉄筋と同様に腐食の問題がある。
（４）上記したように補強用の鉄筋が腐食してコンクリート製の硬質覆工層の強度が著しく低下すると、岩盤斜面や硬質覆工層の崩落事故を誘発する危険があり、その改善技術の提案が望まれている。 The conventional slope stabilization technology described above has the following problems.
(1) Unlike normal flat reinforced concrete structures, the slope in the natural state that forms the reinforcement surface has large and small irregularities. Therefore, in addition to being forced to process the reinforcing bars on the spot according to the unevenness of the site, it is necessary to lift and place heavy reinforcing bars on slopes with poor scaffolding, which requires a lot of labor and time to install the reinforcing bars.
(2) There is a problem that reinforcing reinforcing bars are easily corroded by chloride ions peculiar to the coast.
Rebars covered with a rust-proof coating such as an epoxy resin with high rust-proof performance are also known as countermeasures, but the rust-proof coating cracks and peels off during bending of the reinforcing bars, leaving concerns about rebar corrosion.
(3) Although a lath net is used to improve the adhesion of the shotcrete, the metal lath net has a problem of corrosion as well as the reinforcing bar.
(4) As mentioned above, if the reinforcing steel bars corrode and the strength of the concrete hard lining layer is significantly reduced, there is a risk of causing a collapse of the rock slope or the hard lining layer. Suggestion is desired.

本発明は以上の点に鑑みてなされたもので、その目的とするところは作業性の改善と、硬質覆工層の長期に亘る強度保証が図れる斜面の安定化工法を提供することにある。

本発明はつぎのいずれかひとつの効果を奏する。
（１）非金属製（非腐食性）の補強ネット状物を、硬質覆工層の補強材として使用することで、従来の鉄筋やラス網の使用を省略できると共に、施工後における塩化物イオンによる腐食の問題を解消できる。
そのため、硬質覆工層の強度を長期に亘って保証することができる。

(3) By combining the hard lining layer reinforced with the reinforcing net-like material and the anchor, the holding power of the hard lining layer and the slope is increased, and the performance of preventing the collapse of the hard lining layer and the slope is enhanced.
In particular, when the anchor is made of fiber, the problem of corrosion of the anchor can be solved.
(4) By using a fiber reinforced net, the toughness of the hard lining layer is remarkably improved compared to the case where reinforcing reinforcing bars are arranged.

以下図面を参照しながら本発明の一実施の形態について説明する。
（１）補強ネット状物の敷設工
図１に一部を省略した安定処理後の斜面１０の断面図を示す。図２に安定処理前の斜面１０の断面図を示す。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(1) Laying work of reinforcing net-like object FIG. 1 shows a cross-sectional view of the slope 10 after the stabilization process with a part omitted. FIG. 2 shows a cross-sectional view of the slope 10 before the stabilization treatment.

図２に示すように、斜面１０の安定化をする範囲に亘り、可撓性を有する非金属製（非腐食性）の補強ネット状物３０を敷設する。補強ネット状物３０の敷設に際し、斜面１０に点在させたスペーサ２０を介して斜面１０から所定距離を隔てて敷設する。   As shown in FIG. 2, a non-metallic (non-corrosive) reinforcing net 30 having flexibility is laid over a range where the slope 10 is stabilized. When laying the reinforcing net-like object 30, the reinforcing net-like object 30 is laid at a predetermined distance from the slope 10 via the spacers 20 scattered on the slope 10.

補強ネット状物３０は補強用鉄筋およびラス網の代替物で、引張強度に優れ、かつ塩化物イオンに対する耐腐食性と耐候性に優れた素材でネット状に形成したものである。
その素材としては、アラミド繊維、ナイロン繊維、ビニロン繊維、ポリプロピレン繊維、ポリエチレン繊維、アクリル繊維、炭素繊維、高強度ポリエチレン樹脂繊維群より選択される一種または複数種の繊維を使用できる。
そのなかでもアラミド繊維が好適である。アラミド繊維は一般繊維と比べて引張強度が格段高いことと、コンクリートとの付着性が良好であることと、コンクリートになじみ易いからである。
また繊維の形態は、複数の繊維を撚り合せて直径１ｍｍ〜３ｍｍのロープ状に形成したものを使用するか、或いはこのロープを編網した網形態のものを使用する。
補強ネット状物３０を編網して形成する場合におけるロープ径や網目寸法は、要求される設計強度に応じて適宜選択するものとする。 The reinforcing net 30 is a substitute for reinforcing steel bars and lath nets, and is formed into a net with a material excellent in tensile strength and excellent in corrosion resistance and weather resistance against chloride ions.
As the material, one or more kinds of fibers selected from the group of aramid fibers, nylon fibers, vinylon fibers, polypropylene fibers, polyethylene fibers, acrylic fibers, carbon fibers, and high-strength polyethylene resin fibers can be used.
Of these, aramid fibers are preferred. This is because aramid fibers have a markedly higher tensile strength than ordinary fibers, good adhesion to concrete, and are easily compatible with concrete.
In addition, the fiber is formed by twisting a plurality of fibers into a rope shape having a diameter of 1 mm to 3 mm, or a net shape obtained by knitting the rope.
In the case where the reinforcing net 30 is formed by knitting, the rope diameter and mesh size are appropriately selected according to the required design strength.

スペーサ２０は、補強ネット状物３０を斜面１０から離隔して敷設するための補助具で、本例ではピンタイプのスペーサ２０である場合について説明する。
スペーサ２０のピン部を斜面１０に打設し、スペーサ２０の上部に膨出した鍔部２１と着脱可能なキャップ２２との間に補強ネット状物３０の一部を挟持して固定する。尚、スペーサ２０は、図示した形態の他に公知の各種スペーサを使用可能である。 The spacer 20 is an auxiliary tool for laying the reinforcing net 30 away from the slope 10, and in this example, a case where it is a pin type spacer 20 will be described.
A pin portion of the spacer 20 is driven on the inclined surface 10, and a part of the reinforcing net 30 is sandwiched and fixed between the flange portion 21 bulging above the spacer 20 and the removable cap 22. The spacer 20 can use various known spacers in addition to the illustrated embodiment.

鉄筋を現地加工した従来と異なり、現場に搬入した軽量な補強ネット状物３０を広げて斜面１０の凹凸に合わせて敷設するたけであるから、補強ネット状物３０の敷設に要する労力や時間を従来と比べて著しく削減できる。   Unlike the conventional method in which the reinforcing bars are processed locally, the lightweight reinforcement net 30 that has been carried to the site is only expanded and laid according to the unevenness of the slope 10, so that the labor and time required to lay the reinforcement net 30 are reduced. This can be significantly reduced compared to the conventional case.

（２）コンクリートの吹付工
つぎに図３に示すように、斜面１０へ向けてコンクリートを吹き付けて硬質覆工層４０を形成し、硬質覆工層４０で斜面１０の表層部を覆うことで補強する。
吹き付けたコンクリートは補強ネット状物３０を透過して斜面１０に付着しながらその層厚を増していく。補強ネット状物３０が所定の被り厚に達するまでコンクリートを吹き付ける。 (2) Concrete spraying work As shown in FIG. 3, concrete is sprayed toward the slope 10 to form the hard lining layer 40, and the hard lining layer 40 covers the surface layer portion of the slope 10 for reinforcement. To do.
The sprayed concrete penetrates the reinforcing net 30 and adheres to the slope 10 and increases its layer thickness. Concrete is sprayed until the reinforcing net 30 reaches a predetermined covering thickness.

（３）補強覆工層の特性
コンクリート中に埋没された補強ネット状物３０は、硬化した補強覆工層４０の補強部材として機能するため、硬化後の補強覆工材４０の破損防止と崩落防止に役立つだけでなく、最終的に斜面１０の保持に大きく貢献する。
また補強ネット状物３０はそれ自身が優れた耐腐食性を有するので、別途に防錆被覆をすることなく、塩化物イオンによる腐食の心配がまったくなく、長期間に亘る強度保証が可能となる。 (3) Characteristics of the reinforcing lining layer The reinforcing net 30 embedded in the concrete functions as a reinforcing member for the cured reinforcing lining layer 40. Therefore, the cured reinforcing lining material 40 is prevented from being damaged and collapsed. In addition to helping to prevent, it ultimately contributes greatly to the retention of the slope 10.
Further, since the reinforcing net 30 itself has excellent corrosion resistance, there is no fear of corrosion due to chloride ions without any additional rust-proof coating, and strength can be guaranteed over a long period of time. .

また補強覆工層４０の補強材として、アラミド繊維製の補強ネット状物３０を使用した場合、従来の鉄筋補強と比べて補強覆工層４０の靭性が格段に向上することが、各種の実験により確認することができた。   In addition, when a reinforcing net 30 made of aramid fiber is used as a reinforcing material for the reinforcing lining layer 40, various experiments have shown that the toughness of the reinforcing lining layer 40 is significantly improved compared to conventional reinforcing steel reinforcement. It was possible to confirm.

（４）その他の実施の形態１
図４は補強ネット状物３０に改良を加えた他の形態を示す。
本例は補強ネット状物３０を構成する繊維束３１に沿って塑性変形可能な非金属製の補強線３２を付加したものである。
補強線３２としては、例えばポリエステル、ポリプロピレン、ポリエチレン等のモノフィラメント（剛毛）を使用可能である。
補強線３２を付加する形態としては、繊維束３１の外周に配置することの他に、繊維束３１の内部に配置してもよく、またその付加本数も単数または複数の何れでもよい。
補強線３２を付加することで、軽くて柔らかい補強ネット状物３０に形状保持機能を付与できるので、斜面１０の凹凸形状に合わせて曲げ加工ができるだけでなく、その曲げ加工に特別な専用機器を必要としない。
補強ネット状物３０に付与する最低強度は、コンクリート吹付時に容易に変形しないだけの強度設定で十分である。
本例に合っては、補強ネット状物３０を斜面の凹凸形状に沿わせて配置できるので、補強ネット状物３０のかぶりを均一化できる利点がある。 (4) Other embodiment 1
FIG. 4 shows another embodiment in which the reinforcing net 30 is improved.
In this example, a non-metallic reinforcing wire 32 that is plastically deformable along the fiber bundle 31 constituting the reinforcing net 30 is added.
As the reinforcing wire 32, for example, monofilaments (bristles) such as polyester, polypropylene, and polyethylene can be used.
As a form of adding the reinforcing wire 32, in addition to being arranged on the outer periphery of the fiber bundle 31, it may be arranged inside the fiber bundle 31, and the number of the added wires may be either single or plural.
By adding the reinforcing wire 32, it is possible to give a shape retaining function to the light and soft reinforcing net-like object 30, so that not only bending can be performed according to the uneven shape of the slope 10, but also a special dedicated device for the bending process. do not need.
The minimum strength imparted to the reinforcing net 30 is sufficient to set the strength so as not to be easily deformed when the concrete is sprayed.
In accordance with this example, the reinforcing net 30 can be arranged along the uneven shape of the slope, so that there is an advantage that the covering of the reinforcing net 30 can be made uniform.

（５）その他の実施の形態２
また以上は斜面１０を硬質覆工層１０で被覆する形態について説明した、図１に示すように補強ネット状物３０の敷設に先行して、斜面１０の複数箇所にアンカー５０を設けておき、これらのアンカー５０の頭部を硬質覆工層４０に一体に接続してもよい。
アンカー５０は公知のグラウンドアンカー、ロックボルト、アンカーボルトでもよいが、アラミド繊維束を樹脂で覆って棒状に形成した非金属製のアンカーテンドンを使用すると、アンカー５０が腐食する問題を回避することができる。
尚、アンカー５０の頭部は図示しない支圧板を用いて硬質覆工層４０の表面側に固定するか、或いは硬質覆工層４０中に埋設するものとし、その固定形態は何れでもよい。 (5) Other embodiment 2
Further, as described above, the embodiment in which the slope 10 is covered with the hard lining layer 10 has been described. As shown in FIG. 1, anchors 50 are provided at a plurality of locations on the slope 10 prior to the laying of the reinforcing net 30. The heads of these anchors 50 may be integrally connected to the hard lining layer 40.
The anchor 50 may be a known ground anchor, a lock bolt, or an anchor bolt. However, when a non-metallic uncurtain don formed by covering an aramid fiber bundle with a resin and forming a rod shape, the problem of corrosion of the anchor 50 may be avoided. it can.
The head of the anchor 50 is fixed to the surface side of the hard lining layer 40 using a bearing plate (not shown), or is embedded in the hard lining layer 40, and any fixing form may be used.

本例のように補強ネット状物３０で補強された硬質覆工層４０とアンカー５０とを組み合わせることで、斜面１０の深部から反力を得て、補強ネット状物３０と斜面１０の保持力が増して崩落抑止効果がさらに高くなる。   By combining the hard lining layer 40 reinforced with the reinforcing net 30 and the anchor 50 as in this example, a reaction force is obtained from the deep part of the slope 10, and the holding power of the reinforcing net 30 and the slope 10 is obtained. As a result, the fall prevention effect is further enhanced.

（６）その他の実施の形態３
以上は斜面１０の全面を、補強ネット状物３０で補強した硬質覆工層４０で覆う場合について説明したが、硬質覆工層４０で斜面１０を部分的に被覆するようにしてもよい。この場合はアンカー５０と組み合わせることが望ましい。
(6) Other embodiment 3
Although the case where the entire surface of the slope 10 is covered with the hard lining layer 40 reinforced with the reinforcing net 30 has been described above, the slope 10 may be partially covered with the hard lining layer 40. In this case, it is desirable to combine with the anchor 50.
