本発明はアンカー施工方法に係り、特に削孔作業空間の
確保が困難な急斜面や掘削壁面の土留め工事やよう壁工
事などに対して好適なアンカー施工方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an anchor construction method, and is particularly suitable for steep slopes where it is difficult to secure a drilling work space, earth retaining work on excavated walls, wall construction, etc. Regarding anchor construction methods.
一般にアンカー工法は、地盤を削孔してアンカ一体を挿
入し、セメントペースト等を注入して施工する。Generally, the anchor construction method involves drilling a hole in the ground, inserting the anchor, and then injecting cement paste or the like.

。Conventionally, when constructing anchors for earth retaining on steep slopes or excavated walls, slope stabilization works, and ground erosion prevention, the second
As shown in the figure, install a hole-drilling machine with the root cutting bottom as a ↓ board, and as the root cutting progresses, drill holes sequentially on the excavation wall surface, or use a scaffold or gantry for work facing the drilling surface. It was common practice to temporarily construct a hole and install a drilling machine in the hole. In the figure, 2 is the earth retaining material, 4 is the cutting bottom or temporary scaffolding, 6 is the hole drilling machine, 8 is the drilling hammer, and 1O is the power equipment.
しかしながら、削孔面の前面に作業空間を確保するのが

また、そのため斜面に樹木などが生い茂っているときは
、広範囲の伐採によって地山の強度が弱められ、更には
樹木伐採による環境上の問題もあった。In addition, when the slopes are overgrown with trees, the strength of the ground is weakened by extensive felling, and the felling of trees also poses environmental problems.

−２９１８２号参照）。The inventors of the present application have already attached a drilling hammer to the tip of a backhoe, and have achieved remarkable results in drilling holes on steep slopes below, such as under cliffs, or on excavated walls. (Special application Hei 1
-29182).
この発明の目的は上記問題点に鑑みなされたもので、高
位置にある削孔面の前面に削孔のための足場や構台を配
設する必要のないアンカー施工方法を提供することであ
る。The object of the present invention has been made in view of the above-mentioned problems, and is to provide an anchor construction method that does not require providing a scaffold or pedestal for drilling holes in front of a drilling surface located at a high position.

は掘削壁面に削孔することを特徴とするものである。In order to achieve the above object, the anchor construction method of the present invention is an anchor construction method for earth retaining work on a steep slope or an excavated wall, in which a backhoe is positioned below the steep slope or excavated wall, and the anchor is attached to the tip of the backhoe. This method is characterized in that a hole is drilled on a steep slope or excavation wall above the backhoe using a hole-drilling hammer.
また、前記削孔ハンマは作業台を仮設することもできる
。Further, the drilling hammer can also be used as a temporary workbench.

孔面の前面に重機を配置するための大がかりな足場等を
設けることなく、高い位置の削孔が可能となる。According to the above configuration, the backhoe can be placed on the ground below the steep slope or the excavation wall surface, and a drilling hammer can be attached to the tip of the backhoe to drill a hole on the steep slope or the excavation wall surface. It is possible to drill holes at high positions without having to install large-scale scaffolding for placing heavy machinery.
そのために経済的であり、大１ｊに工期の短縮を図るこ
とができる。Therefore, it is economical and the construction period can be significantly shortened.
以下１本発明の一実施例を図面に基づいて説明する。 An embodiment of the present invention will be described below based on the drawings.
第１図に示すように、バックホー５０の先端のクラムシ
ェル（図示せず）を取外して削孔ハンマ５２を取付けた
ものを、急斜面５４の下方に配置して斜面５４の削孔を
行う。As shown in FIG. 1, a backhoe 50 with a clamshell (not shown) at the tip thereof removed and a drilling hammer 52 attached thereto is placed below a steep slope 54 to drill holes in the slope 54.
バックホー５０のアーム５６を延ばすことによって、斜
面５４の高い位置であっても削孔５８をすることができ
る。By extending the arm 56 of the backhoe 50, the hole 58 can be drilled even at a high position on the slope 54.
図の例では、削孔ハンマ５２に作業台６０を設けである
。こうすることによって削孔後も、アンカ一体の挿入、
セメントペーストの注入等の作業を容易に行うことがで
きる。In the illustrated example, the drilling hammer 52 is provided with a workbench 60. By doing this, even after drilling, the anchor can be inserted as a single piece,
Operations such as cement paste injection can be performed easily.
また、本実施例では急斜面に施工する場合について説明
しているが、垂直な掘削壁面の高い位置は勿論のこと、
勾配４５度以下の緩斜面についても、同様に施工するこ

また、本実施例のように、バックホーを用いることによ
って容易に施工することができるが、バックホーに限定
されるものではなく、他の動力クレーン等の重機を用い
ることによっても同様の効果を奏することができる。In addition, although this example describes the case of construction on a steep slope, it goes without saying that construction is performed at a high position on a vertical excavation wall.
It can be constructed in the same way on gentle slopes with a slope of 45 degrees or less. Similar effects can also be achieved by using other heavy equipment such as power cranes.
本実施例によれば、アンカーエのための仮設工事を大巾
に省略することができ、しかもなおアンカー自体の精度
・品質は従来の方法によるものと全く変わらない。According to this embodiment, temporary construction work for the anchorage can be largely omitted, and the accuracy and quality of the anchor itself are no different from those of conventional methods.
上述のとおり１本発明によれば、急斜面等の高い位置に
アンカーの施工をするに当り、アンカー施工部の下方に
重機を配置することによって、がなりの仮設工事が省略
され、そのため工期が大目１に短縮され、極めて大きい
経済的効果を奏することができる。As mentioned above, according to the present invention, when constructing an anchor at a high position such as a steep slope, by placing heavy equipment below the anchor construction part, temporary construction work is omitted, and the construction period is therefore increased. It can be shortened to 1 second, and can have an extremely large economical effect.
