Description

本発明は、既設の土留め壁を補強する土留め壁補強構造に関する。   The present invention relates to a retaining wall reinforcing structure for reinforcing an existing retaining wall.

従来、地山や盛土などの側壁面に設けられている既設の土留め壁を補強するため、土留め壁の背面側の地盤に設置した補強杭に、土留め壁の前面を覆うように設置した補強ネットを固定してなる補強構造が知られている（例えば、特許文献１参照。）。   In order to reinforce the existing earth retaining wall provided on the side wall surface of the ground, embankment, etc., the reinforcement pile installed on the ground on the back side of the earth retaining wall is installed to cover the front of the earth retaining wall There is known a reinforcing structure formed by fixing the reinforcing nets (see, for example, Patent Document 1).

特開２０１３−２５９６６０号公報JP, 2013-259660, A

しかしながら、上記特許文献１の補強構造の場合、地震により地盤が揺さぶられると、土留め壁には通常よりも高い土圧が作用するので、土留め壁が損傷してしまうことがあった。この土留め壁は補強ネットで覆われているので大崩れしないようになってはいるが、より効果的に土留め壁を補強することが望まれている。   However, in the case of the reinforcing structure of Patent Document 1, when the ground is shaken by an earthquake, earth pressure higher than normal acts on the earth retaining wall, so the earth retaining wall may be damaged. Although this earth retaining wall is covered with a reinforcing net so that it does not collapse greatly, it is desired to reinforce the earth retaining wall more effectively.

本発明の目的は、土留め壁をより好適に補強することができる土留め壁補強構造を提供することである。   An object of the present invention is to provide a retaining wall reinforcing structure capable of reinforcing a retaining wall more suitably.

上記目的を達成するため、この発明は、土留め壁補強構造であって、

前記補強杭の上端部と前記土留め壁の上端部とを連結している連結部材と、
前記土留め壁の前面から前記補強杭に達するように貫入され、前記土留め壁と前記補強杭とを連結している一体化部材と、
前記土留め壁の前面を覆う被覆部材と、

特に、この土留め壁補強構造であれば、土留め壁と補強杭の間の地盤がこの補強構造と一体となって挙動する疑似擁壁とすることができる。
つまり、この土留め壁補強構造は、既設の土留め壁を連結部材と一体化部材とによって補強杭に連結したことで、土留め壁と補強杭の間に挟んだ地盤を土留め壁と一体化するようにして、その土留め壁の厚みを増すのと同等の補強を行うことができる。こうすることで、既設の土留め壁の耐震性を向上させることができる。
また、土留め壁の前面を補強ネットなどの被覆部材で覆うようにすれば、土留め壁の一部が損傷して部分的に崩壊しそうになってもその箇所を被覆部材で押さえることができる。また、崩壊してしまったものを被覆部材の張力によって拘束することができる。こうして崩壊に伴う被害を抑えることができる。
また、被覆部材を一体化部材の一端部に固定するようにすれば、土留め壁の前面を覆う被覆部材を一体化部材を介して補強杭に連結し、土圧が作用する土留め壁を補強杭側に引き留めて支えることができ、既設の土留め壁をより好適に補強することができる。 In the earth retaining wall reinforcing structure having such a configuration, the earth retaining wall on which the earth pressure acts is reinforced by connecting the existing earth retaining wall to the reinforcing pile installed on the back side by the connecting member and the integrated member. It can be suitably reinforced as supported by a pile.
In particular, with this earth retaining wall reinforcing structure, a ground between the earth retaining wall and the reinforcing pile can be made to be a pseudo retaining wall which behaves integrally with this reinforcing structure.
That is, in this earth retaining wall reinforcing structure, the existing earth retaining wall is connected to the reinforcing pile by the connecting member and the integral member, whereby the ground sandwiched between the earth retaining wall and the reinforcing pile is integrated with the earth retaining wall In such a case, reinforcement equivalent to increasing the thickness of the earth retaining wall can be performed. By doing this, it is possible to improve the earthquake resistance of the existing earth retaining wall.
Also, if the front surface of the earth retaining wall is covered with a covering member such as a reinforcing net, even if a part of the earth retaining wall is damaged and it is likely to partially collapse, the place can be held by the covering member . Also, the one that has collapsed can be restrained by the tension of the covering member. In this way, damage caused by the collapse can be suppressed.
In addition, if the covering member is fixed to one end of the integrated member, the covering member covering the front surface of the earth retaining wall is connected to the reinforcing pile via the integrated member, and the earth retaining wall on which earth pressure acts It is possible to hold and support the reinforcement pile side, and the existing earth retaining wall can be more suitably reinforced.

また、望ましくは、

And this earth retaining wall 50 has a shape that can secure stability while being leaned against a ground, an embankment, a cut slope and the like by its own weight.
A railway track R is laid on the front side of the earth retaining wall 50. Also, on the back side of the earth retaining wall 50, a site boundary L of the ground G is set.

土留め壁補強構造１００は、図１、図２に示すように、土留め壁５０の背面側の地盤Ｇに設置した補強杭１０と、補強杭１０の上端部１０ａと土留め壁５０の上端部５０ａとを連結している連結部材２０と、土留め壁５０の前面から補強杭１０に達するように貫入され、土留め壁５０と補強杭１０とを連結している一体化部材３０と、を備えている。   As shown in FIG. 1 and FIG. 2, the earth retaining wall reinforcing structure 100 has a reinforcing pile 10 installed on the ground G on the back side of the earth retaining wall 50, an upper end 10 a of the reinforcement pile 10 and an upper end of the earth retaining wall 50 A connecting member 20 connecting the portion 50a, and an integrated member 30 which is penetrated from the front surface of the earth retaining wall 50 so as to reach the reinforcing pile 10 and connects the earth retaining wall 50 and the reinforcing pile 10; Is equipped.

補強杭１０は、地盤Ｇに鉛直方向に埋設されており、用地境界Ｌよりも土留め壁５０側に設置されている。また、補強杭１０は、土留め壁５０が延在する範囲に所定間隔をあけて複数設けられている。
この補強杭１０は、地盤Ｇに鉛直向きに形成された掘削孔にモルタル又はコンクリートを打設して設けられた杭であり、杭の内部には鉄筋や鉄骨など（図示省略）が配設されている。 The reinforcement pile 10 is buried in the ground G in the vertical direction, and is installed closer to the earth retaining wall 50 than the site boundary L. Further, a plurality of reinforcing piles 10 are provided at predetermined intervals in the range in which the earth retaining wall 50 extends.
The reinforcement pile 10 is a pile provided by placing mortar or concrete in a drilled hole formed in the ground direction G in the vertical direction, and reinforcing bars, steel frames, etc. (not shown) are disposed inside the pile. ing.

連結部材２０は、モルタル又はコンクリートからなる部材であり、補強杭１０と一体化させるように補強杭１０の上端部１０ａに被せて設けられている。
また、土留め壁５０の上端部５０ａに、補強杭１０側に突出するアンカー２０ａを予め定着させておき、そこへモルタル又はコンクリートを打設して連結部材２０を形成することで、連結部材２０内にアンカー２０ａを取り込むようにして、連結部材２０と土留め壁５０を接続している。
こうして、補強杭１０と土留め壁５０は連結部材２０を介して連結されている。 The connecting member 20 is a member made of mortar or concrete, and is provided on the upper end portion 10 a of the reinforcing pile 10 so as to be integrated with the reinforcing pile 10.
Further, the anchor 20a protruding toward the reinforcing pile 10 is fixed in advance to the upper end 50a of the earth retaining wall 50, and mortar or concrete is cast there to form the connecting member 20, whereby the connecting member 20 is formed. The connection member 20 and the retaining wall 50 are connected in such a manner that the anchor 20a is taken inside.
Thus, the reinforcing pile 10 and the earth retaining wall 50 are connected via the connecting member 20.

一体化部材３０は、土留め壁５０の前面から補強杭１０に向けて斜め下方に傾斜するように形成された掘削孔にモルタル又はコンクリートを打設して設けられた部材であり、その内部には鉄筋３３が配設されている。
この一体化部材３０は、１本の補強杭１０に対し複数（本実施形態では３つ）設けられており、複数の一体化部材３０は、それぞれの高さ位置が異なるように補強杭１０に向けて貫入されている。補強杭１０に貫入した一体化部材３０は、その補強杭１０と一体化している。
なお、本実施形態では一体化部材３０は補強杭１０を貫通しておらず、一体化部材３０の先端側が用地境界Ｌを超えないように設けられている。 The integrated member 30 is a member provided by pouring mortar or concrete into a drilled hole formed to be inclined obliquely downward from the front surface of the earth retaining wall 50 toward the reinforcing pile 10, The rebar 33 is arranged.
A plurality (three in the present embodiment) of this integrated member 30 is provided for one reinforcing pile 10, and the plurality of integrated members 30 are provided on the reinforcing pile 10 so that their height positions are different. It is penetrated towards. The integrated member 30 penetrating the reinforcement pile 10 is integrated with the reinforcement pile 10.
In the present embodiment, the integrated member 30 does not penetrate the reinforcing pile 10, and the tip end side of the integrated member 30 is provided so as not to exceed the site boundary L.

この土留め壁補強構造１００を構成する補強杭１０、連結部材２０、一体化部材３０と、既設の土留め壁５０は、いずれも主要部がモルタル又はコンクリートからなる構造体であるので、各部材はそれぞれ親和性よく接合している。   Each of the reinforcing pile 10, the connecting member 20, the integrated member 30, and the existing earth retaining wall 50, which constitute the earth retaining wall reinforcing structure 100, is a structure whose main part is mortar or concrete, each member Are each joined with good affinity.

このように、本実施形態の土留め壁補強構造１００は、既設の土留め壁５０と、その土留め壁５０の背面側に設置した補強杭１０とを、連結部材２０と一体化部材３０とで連結して一体化した構造を有している。
このような土留め壁補強構造１００であれば、土留め壁５０と補強杭１０の間の地盤も補強構造の一部とすることができ、その地盤を含んだ土留め壁補強構造１００を疑似擁壁１００ａと見なすことができる。そして、土留め壁５０と補強杭１０の間の地盤が土留め壁補強構造１００と一体となって挙動することで、土留め壁補強構造１００がより重厚な疑似擁壁１００ａとなる。 As described above, in the earth retaining wall reinforcing structure 100 of the present embodiment, the existing earth retaining wall 50 and the reinforcing pile 10 installed on the back side of the earth retaining wall 50 are combined with the connecting member 20 and the integral member 30. It has an integrated structure connected by
With such earth retaining wall reinforcing structure 100, the ground between the earth retaining wall 50 and the reinforcing pile 10 can also be part of the reinforcing structure, and the earth retaining wall reinforcing structure 100 including the ground is simulated. It can be considered as a retaining wall 100a. Then, the ground between the earth retaining wall 50 and the reinforcement pile 10 behaves integrally with the earth retaining wall reinforcing structure 100, whereby the earth retaining wall reinforcing structure 100 becomes a heavy artificial retaining wall 100a.

以上のように、本実施形態の土留め壁補強構造１００であれば、連結部材２０と一体化部材３０とによって、土留め壁５０をその背面側に設置した複数の補強杭１０に連結することで、土圧が作用する土留め壁５０を補強杭１０で支えるように好適に補強することができる。
特に、この土留め壁補強構造１００であれば、土留め壁５０と補強杭１０の間の地盤がこの補強構造と一体となって挙動する疑似擁壁１００ａとすることができる。 As mentioned above, if it is earth retaining wall reinforcement structure 100 of this embodiment, connecting earth retaining wall 50 to a plurality of reinforcement piles 10 installed in the back side by connecting member 20 and unification member 30. Thus, the earth retaining wall 50 on which the earth pressure acts can be suitably reinforced so as to be supported by the reinforcement pile 10.
In particular, with this earth retaining wall reinforcing structure 100, the ground between the earth retaining wall 50 and the reinforcing pile 10 can be a pseudo retaining wall 100a which behaves integrally with this reinforcing structure.

つまり、土留め壁補強構造１００は、既存の土留め壁５０を、連結部材２０と一体化部材３０とによって複数の補強杭１０に連結したことで、土留め壁５０と補強杭１０の間に挟んだ地盤を土留め壁５０と一体化するようにして、その土留め壁５０の厚みを増すのと同等の補強を行うことができる。こうすることで、既存の土留め壁５０の耐震性を向上させることができる。
このような補強構造によれば、土留め壁５０の前面側に張り出すような厚みを有する補強部材を設置することなく、土留め壁５０の厚みを増すのと同等の補強を行うことができるので、土留め壁５０の前面側に施工用地がない場合でも、土留め壁５０をより効果的に補強することができる。 That is, the earth retaining wall reinforcing structure 100 is connected between the earth retaining wall 50 and the reinforcement pile 10 by connecting the existing earth retaining wall 50 to the plurality of reinforcement piles 10 by the connecting member 20 and the integrated member 30. By integrating the sandwiching ground with the earth retaining wall 50, reinforcement equivalent to increasing the thickness of the earth retaining wall 50 can be performed. By doing this, the earthquake resistance of the existing earth retaining wall 50 can be improved.
According to such a reinforcing structure, reinforcement equivalent to increasing the thickness of the earth retaining wall 50 can be performed without installing a reinforcement member having a thickness projecting to the front side of the earth retaining wall 50. Therefore, even when there is no construction site on the front side of the earth retaining wall 50, the earth retaining wall 50 can be reinforced more effectively.

また、この土留め壁補強構造１００であれば、用地境界Ｌよりも土留め壁５０側に補強杭１０を設置し、用地境界Ｌを超えないように一体化部材３０を設けるようにして、疑似擁壁１００ａを構築することができるので、既存の土留め壁５０と用地境界Ｌとの間が狭隘な箇所であっても、土留め壁５０をより効果的に補強することができる。   Further, in the case of this earth retaining wall reinforcing structure 100, the reinforcement pile 10 is installed on the earth retaining wall 50 side of the site boundary L, and the integrated member 30 is provided so as not to exceed the site boundary L. Since the retaining wall 100a can be constructed, even if the existing earth retaining wall 50 and the site boundary L are narrow places, the earth retaining wall 50 can be reinforced more effectively.

なお、本発明は上記実施形態に限られるものではない。
例えば、図３に示すように、土留め壁補強構造１００は、土留め壁５０の前面を覆う被覆部材４０を備えてもよい。
被覆部材４０は、一体化部材３０の一端部３０ａに固定されている。具体的に、被覆部材４０は土留め壁５０の前面に突出するように配設された鉄筋３３の一端部３３ａに固定されている。
被覆部材４０は、耐候性を有する高強度のものであれば、樹脂製の補強ネットや補強シートであっても、金属製の補強ネットや補強シートであってもよい。なお、樹脂製の補強ネットや補強シートは、樹脂繊維からなる複数本の紐を交織あるいは交編して製造することができる。金属製の補強ネットや補強シートは、複数本のワイヤーやワイヤー撚り線を交織あるいは交編して製造することができる。
この被覆部材４０を土留め壁５０の前面に設ける場合、被覆部材４０の上端と下端を土留め壁５０に固定するように、一体化部材３０の一端部３０ａが土留め壁５０の上端側と下端側に露出する位置に、それぞれ一体化部材３０を設けるようにすることが好ましい。
このように、土留め壁５０の前面を覆う被覆部材４０が一体化部材３０の一端部３０ａに固定されていれば、一体化部材３０を介して被覆部材４０が補強杭１０に接続されるので、土圧が作用する土留め壁５０を被覆部材４０で補強杭１０側に引き留めて支え、その土留め壁５０をより好適に補強することができる。 The present invention is not limited to the above embodiment.

The covering member 40 may be a reinforcing net or a reinforcing sheet made of a resin, or a reinforcing net or a reinforcing sheet made of a metal as long as the covering member 40 has high strength having weather resistance. The resin-made reinforcing net and the reinforcing sheet can be manufactured by cross-weaving or cross-kniting a plurality of strings made of resin fibers. The metal reinforcing net and the reinforcing sheet can be manufactured by cross-weaving or intertwining a plurality of wires or wire strands.
When the covering member 40 is provided on the front surface of the earth retaining wall 50, one end 30a of the integral member 30 is fixed to the upper end side of the earth retaining wall 50 so as to fix the upper end and the lower end of the covering member 40 to the earth retaining wall 50 Preferably, the integrated members 30 are provided at the positions exposed on the lower end side.
Thus, if the covering member 40 covering the front surface of the earth retaining wall 50 is fixed to one end 30 a of the integrated member 30, the covering member 40 is connected to the reinforcing pile 10 via the integrated member 30. The earth retaining wall 50 on which earth pressure acts can be retained and supported by the covering member 40 on the reinforcing pile 10 side, and the earth retaining wall 50 can be reinforced more suitably.

なお、以上の実施の形態においては、一体化部材３０が補強杭１０を貫通していない場合を例に説明したが、一体化部材３０は補強杭１０を貫通していてもよい。その場合でも一体化部材３０の先端側が用地境界Ｌを超えないように設けられているようにする。   In addition, in the above embodiment, although the case where the integral member 30 did not penetrate the reinforcement pile 10 was demonstrated to the example, the integral member 30 may penetrate the reinforcement pile 10.
