〈産業上の利用分野〉
本発明はロックボルト等の施工方法と装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method and apparatus for constructing rock bolts and the like.
〈従来の技術〉
岩盤に削孔し、内部にモルタルを充填した後、ボルトを
圧入する工法が存在する。<Conventional technology> There is a method of drilling holes in rock, filling the inside with mortar, and then press-fitting bolts.
く本発明が解決しようとする問題点〉
従来のロックボルト工法では、特に上向きに削孔した場
合に次のような問題点が存在する。Problems to be Solved by the Present Invention The conventional rock bolt construction method has the following problems, especially when drilling upwards.
くイ〉内部のモルタルがたれ下がって孔外へ露出してき
やすい。〉The mortar inside tends to sag and be exposed outside the hole.
く口〉その結果、孔内のモルタルが充分に充填されない
ことになる。As a result, the mortar in the hole will not be filled sufficiently.
充填が不充分であると、ボルトと岩盤との付着強度が不
足して岩盤固定の目的が達成できない。If the filling is insufficient, the adhesion strength between the bolt and the rock will be insufficient and the purpose of fixing the bolt to the rock will not be achieved.
くハ〉上向き削孔であるとモルタルのたれ下がりだけで
はなく、内部に挿入したボルトも脱落しやす（、予定ど
うりの深度にボルトを固定できない。Kuha> If the hole is drilled upward, not only will the mortar sag, but the bolts inserted inside will also tend to fall out (and the bolts cannot be fixed at the planned depth.
く本発明の目的〉
本発明は、上記の点を改善するためになされたもので、
次のような工法と装置を提供することを目的とする。Purpose of the present invention The present invention has been made to improve the above points,
The purpose is to provide the following construction methods and equipment.

く本発明の構成〉
次に本発明の一実施例について説明する。<B> Rock bolt construction method and device that prevent the mortar filled inside from dripping even if the hole is facing upwards> This prevents insufficient filling of mortar in the hole and maintains the strength as specified. Structure of the present invention: A rock bolt construction method and device that can achieve the desired effect. Structure of the present invention: A rock bolt construction method and device that prevent bolts inserted into holes from falling out. Next, an embodiment of the present invention will be described. .
くイ〉孔閉塞具（第７図）
削孔したアンカ一孔の入口を閉塞するために１第７図の
ような閉塞具を使用する。1. Hole closing tool (Fig. 7) A closing tool as shown in Fig. 7 is used to close the entrance of the drilled anchor hole.
この閉塞具１は、プレート１１の表面にバイブ１２を直
角に溶接して構成する。This obturator 1 is constructed by welding a vibrator 12 to the surface of a plate 11 at right angles.
プレート１１の面積は後述するアンカ一孔の断面積より
も大きい鋼製の板体であり、その中央、すなわちパイプ
１２中夫にはボルト挿入口１４を開孔する。The plate 11 is a steel plate whose area is larger than the cross-sectional area of one anchor hole, which will be described later, and a bolt insertion hole 14 is formed in the center of the plate 11, that is, in the center of the pipe 12.
このボルト挿入口１４の内径は、ボルト外径よりわずか
に太き（構成する。The inner diameter of this bolt insertion port 14 is slightly larger than the bolt outer diameter.
一方、パイプ１２はアンカ一孔の内径よりも多少率さい
外径を有する鋼製のパイプである。On the other hand, the pipe 12 is a steel pipe having an outer diameter slightly larger than the inner diameter of the anchor hole.
そして、このバイブ１２の外周には逆止翼１３を設ける
。A checker blade 13 is provided on the outer periphery of the vibrator 12.
この逆止翼１３は、例えば弾性を有する短冊状の鋼板を
複数枚パイプ外周に、プレート１１側を外向きにひろげ
た状態で固定して構成する。The check blade 13 is constructed by fixing, for example, a plurality of elastic strip-shaped steel plates to the outer periphery of the pipe with the plate 11 side spread outward.
この実施例の形状に限らず、その他の公知の逆止構造で
あれば広く利用できる。Not limited to the shape of this embodiment, any other known check structure can be widely used.
く施工方法〉
次に、本発明の施工方法の一実施例をロックボルトの施
工について説明するが、アンカーボルトその他にも利用
できることは勿論である。Construction Method> Next, an embodiment of the construction method of the present invention will be described for construction of rock bolts, but it goes without saying that it can also be used for anchor bolts and other applications.
く１）削孔（第１図） 公知の方法によって、岩盤にアンカ一孔２を削孔する。1) Drilling holes (Fig. 1) An anchor hole 2 is drilled in the rock by a known method.
く２〉閉塞具の取り付け（第２図）
アンカー２の孔口に、前記した閉塞具１をたたき込んで
閉塞してしまう。2> Attaching the obturator (Fig. 2) The above-mentioned obturator 1 is inserted into the hole of the anchor 2 to occlude it.
く３〉モルタル注入（第３図）
閉塞具１のプレート１１に、開口したボルト挿入孔１４
にモルタル注入管３を挿入する。3> Mortar injection (Fig. 3) Bolt insertion hole 14 opened in plate 11 of obturator 1
Insert the mortar injection pipe 3 into.
そして、モルタル注入管３の先端からモルタル４をアン
カ一孔２の深部へ注入し、順々に抜き出しながらアンカ
一孔２に充填する。Then, mortar 4 is injected into the deep part of the anchor hole 2 from the tip of the mortar injection tube 3, and is filled into the anchor hole 2 while being pulled out one after another.
アンカ一孔２の口元でさらにモルタルを注入すると、閉
塞具１の隙間からモルタルがはみ出して来るので、完全
に充填されたことが確認できる。When more mortar is injected at the mouth of the anchor hole 2, the mortar protrudes from the gap in the obturator 1, so it can be confirmed that it is completely filled.
（第４図）
く４〉ロックボルトの圧入
注入パイプ３を引き抜き、モルタル４が硬化する以前に
、ロックボルト５をボルト挿入孔１４からモルタル４内
に打撃などの力で挿入する。(Fig. 4) 4> Pull out the injection pipe 3 for press-fitting the rock bolt, and before the mortar 4 hardens, insert the rock bolt 5 into the mortar 4 through the bolt insertion hole 14 by force such as impact.
く５〉ボルトの固定
モルタル４が硬化した後、ボルト５の露出部のナツト６
を締め付け、プレート１１を岩盤に固定して完成する。5> After the bolt fixing mortar 4 has hardened, tighten the nut 6 on the exposed part of the bolt 5.
Tighten and fix the plate 11 to the rock to complete.
く本発明の効果〉
本発明は、上記したようになるから次のような効果を期
待できる。Effects of the present invention> Since the present invention is as described above, the following effects can be expected.
〈イ°〉上向きのアンカ一孔であっても、孔内に完全に
モルタルを充填できる。<A> Even if there is only one hole in the anchor pointing upward, the hole can be completely filled with mortar.
く口〉孔底まで完全に充填しであるから、モルタルの抜
は出し、充填不足などによる強度不足の不安がなく、信
頼性の高いロックボルトの施工を行うことができる。Since the hole is completely filled to the bottom of the hole, there is no need to worry about the mortar being drawn out or lack of strength due to insufficient filling, allowing for highly reliable rock bolt construction.
くハ〉ロックボルト用のボルト自体も上向きに挿入した
場合にも脱落することがな（、孔底まで完全に挿入した
まま固定することができる。Kuha> The bolt for the lock bolt itself will not fall off even when inserted upward (and can be fixed while being inserted completely to the bottom of the hole.
