[削孔装置]
<1>全体の構成(図1)
本発明の削孔装置1は、被削孔体Aの削孔機能を有する装置であって、被削孔体Aを、伝達部20の送り出し方向D2と異なる削孔方向D1に向かって削進可能な装置である。
削孔装置1は、先端に設けられた削孔部10と、削孔部10の後端から延出する長尺状の伝達部20と、伝達部20を介して削孔部10を削孔方向D1に送り出す送出部30と、を少なくとも有する。
削孔装置1の削孔機構には各種の公知技術を採用できる。本例ではウォータージェットを用いる場合について説明する。
[Drilling device]
<1> Overall configuration (FIG. 1)
The hole drilling device 1 of the present invention is a device having a hole drilling function of the hole A to be drilled, and the hole A is advanced toward a hole drilling direction D1 different from the feed direction D2 of the transmission unit 20. It is a possible device.
The hole drilling apparatus 1 drills the hole drilling part 10 through the hole drilling part 10 provided at the front end, a long transmission part 20 extending from the rear end of the hole drilling part 10, and the transmission part 20. And at least a delivery unit 30 that sends out in the direction D1.
Various known techniques can be employed for the hole drilling mechanism of the hole drilling apparatus 1. In this example, a case where a water jet is used will be described.

<2>削孔部(図2)
削孔部10は、削孔機能を備える部分である。
本例では、削孔部10は、先端に噴出孔を有するヘッド11と、ヘッド11を伝達部20の軸に対して回転可能に接続するスイベル12と、を備えた棒状体とする。
ヘッド11は削孔部10の長軸に沿って回転しながら、噴出孔から高圧水を噴出する。高圧水はポンプ(図示せず)から高圧ホース22を介して供給を受ける。
ヘッド11の外周面には、高圧水を噴出し破砕屑を後方へ排除するための孔を有する。
<2> Drilling part (Fig. 2)
The hole drilling portion 10 is a portion having a hole drilling function.
In this example, the hole drilling portion 10 is a rod-like body that includes a head 11 having an ejection hole at the tip, and a swivel 12 that rotatably connects the head 11 to the axis of the transmission portion 20.
The head 11 ejects high-pressure water from the ejection hole while rotating along the long axis of the drilling portion 10. High-pressure water is supplied from a pump (not shown) via a high-pressure hose 22.
The outer peripheral surface of the head 11 has a hole for ejecting high-pressure water and removing crushed debris rearward.

<3>伝達部(図2)
伝達部20は、送出部30の送り出しによる力を削孔部10へ伝達する長尺状の部分である。
本例では、伝達部20は、スイベル12の後端と接続して削孔部10に高圧水を供給する高圧ホース22と、高圧ホース22に外挿される筒状の外挿材21と、を備える。
外挿材21と高圧ホース22の双方が可撓性を有するため、伝達部20は任意の部分(屈曲部20a)で、送り出し方向D2に対して屈曲することができる。
<3> Transmitter (Fig. 2)
The transmission unit 20 is a long portion that transmits the force generated by the delivery of the delivery unit 30 to the drilling unit 10.
In this example, the transmission unit 20 includes a high-pressure hose 22 that is connected to the rear end of the swivel 12 and supplies high-pressure water to the drilling unit 10, and a cylindrical extrapolation material 21 that is extrapolated to the high-pressure hose 22. Prepare.
Since both the extrapolation material 21 and the high-pressure hose 22 have flexibility, the transmission portion 20 can be bent with respect to the delivery direction D2 at an arbitrary portion (bending portion 20a).

<3.1>外挿材
外挿材21は、剛性と可撓性とを兼備した部材であり、内部に高圧ホース22を内挿可能な空間を有する。
外挿材21の先端は削孔装置1の供用時にスイベル12の後端に当接する。または、外挿材21の先端をスイベル12の後端に固定可能な構造としてもよい。
本例では、外挿材21として、鋼製のコイルスプリングを採用する。
外挿材21は、後述するように所定の剛性と可撓性を備えていれば、コイルスプリングに限られない。例えば、可撓性の樹脂パイプや、ジャバラ状に加工した金属製パイプなどであってもよい。
<3.1> Extrapolation Material The extrapolation material 21 is a member having both rigidity and flexibility, and has a space in which the high-pressure hose 22 can be inserted.
The tip of the extrapolated material 21 comes into contact with the rear end of the swivel 12 when the drilling device 1 is used. Or it is good also as a structure which can fix the front-end | tip of the extrapolation material 21 to the rear end of the swivel 12. FIG.
In this example, a steel coil spring is employed as the extrapolating material 21.
The extrapolating material 21 is not limited to a coil spring as long as it has predetermined rigidity and flexibility as will be described later. For example, a flexible resin pipe or a metal pipe processed into a bellows shape may be used.

<3.2>外挿材の機能
外挿材21は、削孔時に削孔部10を支持可能な剛性と、弾性変形可能な可撓性とを兼備する。
すなわち、外挿材21は、自然状態において直線状を呈するが、一定の曲げ応力を与えることで長手軸に対して屈曲し、曲げ応力を解除することで、再び直線状に復元する。また、外挿材21の一部分が屈曲しても他の部分は直線状を保持する。
このため、後述するガイド材40などを用いて外挿材21の一部を任意の方向へ屈曲させることで、送出部30の送り出しによる力を、送り出し方向D2と異なる削孔方向D1へ向けて、削孔部10に伝達することができる。
<3.2> Function of Extrapolation Material The extrapolation material 21 has both rigidity capable of supporting the drilling portion 10 during drilling and flexibility capable of elastic deformation.
That is, the extrapolated material 21 exhibits a linear shape in a natural state, but bends with respect to the longitudinal axis by applying a constant bending stress, and restores the linear shape again by releasing the bending stress. Moreover, even if a part of the extrapolated material 21 is bent, the other part maintains a straight shape.
For this reason, by bending a part of the extrapolating material 21 in an arbitrary direction using a guide material 40 or the like, which will be described later, the force generated by the delivery of the delivery unit 30 is directed toward the drilling direction D1 different from the delivery direction D2. , Can be transmitted to the drilling part 10.

<4>送出部
送出部30は、伝達部20を介して削孔部10を削孔方向D1に送り出す機構を備えた部分である。
本例では、送出部30として、被削孔体Aの壁面に反力を取り、伝達部20を把持して送り出し方向D2にスライド可能な構造を採用する。
送出部30によって送り出し方向D2に送り出された伝達部20は、屈曲部20aで屈曲し、送り出し方向D2と異なる削孔方向D1へと押し出される。
なお、伝達部20の送り出しは機械に限らず、人力で行っても良い。
<4> Sending Unit The sending unit 30 is a part provided with a mechanism for sending the drilling unit 10 in the drilling direction D1 via the transmission unit 20.
In this example, a structure that takes a reaction force on the wall surface of the cut hole A, grips the transmission unit 20 and can slide in the delivery direction D2 is adopted as the delivery unit 30.
The transmission part 20 sent in the delivery direction D2 by the delivery part 30 is bent at the bent part 20a and pushed out in the drilling direction D1 different from the delivery direction D2.
Note that the delivery of the transmission unit 20 is not limited to a machine, and may be performed manually.

<5>ガイド材
ガイド材40は、伝達部20の少なくとも一部を屈曲した状態に保持するための部材である。
本例では、ガイド材40として伝達部20の外径に対応したエルボ管を採用する。そのほか、例えば伝達部20を所定方向に案内するようにRを付けた鋼板などを採用しても良い。
なお、ガイド材40は、本発明の必須の構成要素ではない。被削孔体Aの内壁を利用して伝達部20を屈曲させるなどしてもよい。
<5> Guide Material The guide material 40 is a member for holding at least a part of the transmission portion 20 in a bent state.
In this example, an elbow pipe corresponding to the outer diameter of the transmission portion 20 is employed as the guide member 40. In addition, for example, a steel plate with R so as to guide the transmission unit 20 in a predetermined direction may be employed.
The guide material 40 is not an essential component of the present invention. The transmitting portion 20 may be bent using the inner wall of the cut hole A.

<5.1>接続管
接続管41は、ガイド材40を送出部30と接続するための管材である。
本例では、接続管41として、ガイド材40に螺着可能な鋼管を採用する。
接続管41の先端をガイド材に、他端を送出部30にそれぞれ接続する。接続管41の内部には伝達部20を挿通する。
ガイド材40を接続管41に連結することで、被削孔体A内におけるガイド材40の位置決めが容易となる。
<5.1> Connection Pipe The connection pipe 41 is a pipe material for connecting the guide material 40 to the delivery unit 30.
In this example, a steel pipe that can be screwed to the guide member 40 is employed as the connection pipe 41.
The distal end of the connection pipe 41 is connected to the guide member, and the other end is connected to the delivery unit 30. The transmission unit 20 is inserted into the connection pipe 41.
By linking the guide material 40 to the connection pipe 41, the guide material 40 can be easily positioned in the hole A to be cut.

[削孔装置の使用方法]
引き続き、図面を参照しながら本発明に係る削孔装置の使用方法について説明する。
本例では、RC構造物である被削孔体Aにおいて、壁面に対して直角方向に設けたコア孔H1の先端部分から、壁面に対して平行方向に平行孔H2を削孔する場合について説明する(図1)。
[How to use the drilling device]
Next, a method for using the drilling device according to the present invention will be described with reference to the drawings.
In this example, in the drilling hole A which is an RC structure, a case where a parallel hole H2 is drilled in a direction parallel to the wall surface from a tip portion of the core hole H1 provided in a direction perpendicular to the wall surface will be described. (FIG. 1).

<1>ガイド材の配設
送出部30に連結した接続管41の先端に、ガイド材40を螺着する。
ガイド材40を先にして接続管41をコア孔H1内に差し入れ、ガイド材40先端側の開口が平行孔H2の削孔方向D1を向くように位置合わせする。
<1> Arrangement of Guide Material The guide material 40 is screwed to the tip of the connection pipe 41 connected to the delivery unit 30.
The guide member 40 is inserted first, and the connecting pipe 41 is inserted into the core hole H1, and the guide member 40 is positioned so that the opening on the tip side of the guide member 40 faces the drilling direction D1 of the parallel hole H2.

<2>送出部の設置
送出部30を被削孔体Aの壁面にボルトなどで固定する。
<2> Installation of delivery part The delivery part 30 is fixed to the wall surface of the hole A with a bolt or the like.

<3>伝達部の送り出し
送出部30を用いて、伝達部20の外挿材21を把持し、送り出し方向D2(コア孔H1の先端方向)へ送り出す。
伝達部20は、ガイド材40内でガイド材40の内部形状に合わせて弾性変形し、ガイド材40の先端から平行孔H2の削孔方向D1へ直線状に突出する。
伝達部20を送り出すことで、外挿材21の先端部がスイベル12の後端部を前方に押し出し、削孔部10を前進させる。
<3> Sending out of transmission part Using the delivery part 30, the extrapolated material 21 of the transmission part 20 is gripped and sent out in the delivery direction D2 (tip direction of the core hole H1).
The transmission part 20 is elastically deformed in the guide member 40 according to the internal shape of the guide member 40, and protrudes linearly from the tip of the guide member 40 in the drilling direction D1 of the parallel hole H2.
By sending out the transmission part 20, the front-end | tip part of the external insertion material 21 pushes the rear-end part of the swivel 12 ahead, and advances the drilling part 10. As shown in FIG.

<4>平行孔の削孔
ウォータージェットを稼働させ、削孔部10の噴出孔から高圧水を噴出させながら、所定の削進速度で伝達部20を送り出し方向D2へ押し込んで行く。
削孔部10は伝達部20に押し出されて、被削孔体Aの内部を、削孔方向D1に向かって直線状に削進してゆく。
<4> Drilling a parallel hole The water jet is operated, and the high pressure water is ejected from the ejection hole of the drilling part 10 while the transmission part 20 is pushed in the delivery direction D2 at a predetermined cutting speed.
The hole drilling part 10 is pushed out by the transmission part 20, and the inside of the drilled hole body A is linearly advanced toward the hole drilling direction D1.

<5>屈曲角度について
本例では、削孔方向D1と送り出し方向D2との交角(屈曲角度)θを90°としたが、これに限られない。
削孔装置1の用途に応じて、屈曲角度θを[0°<θ<180°]の範囲で任意に設定可能である。
<5> Bending angle In this example, the intersection angle (bending angle) θ between the drilling direction D1 and the feeding direction D2 is set to 90 °, but is not limited thereto.
The bending angle θ can be arbitrarily set within a range of [0 ° <θ <180 °] according to the use of the hole drilling device 1.

[削孔装置を他の機構とした実施例]
実施例1では、削孔装置1にウォータージェット機構を採用したが、これに限られない。
例えば、電動ハンマードリルや振動ドリルなどの、電気ドリル機構を採用することができる。この場合、削孔部10にはビット部とモータを含み、伝達部20には送電コードと外挿材21を含む。
また、ロータリー削孔機構やエア式のハンマードリルなどを採用してもよい。
[Example in which the hole drilling device is another mechanism]
In Example 1, although the water jet mechanism was employ | adopted for the hole drilling apparatus 1, it is not restricted to this.
For example, an electric drill mechanism such as an electric hammer drill or a vibration drill can be employed. In this case, the drilling portion 10 includes a bit portion and a motor, and the transmission portion 20 includes a power transmission cord and an extrapolating material 21.
Moreover, you may employ | adopt a rotary hole drilling mechanism, an air-type hammer drill, etc.

[軸強化ホースを用いた実施例]
実施例1では、伝達部20を外挿材21と高圧ホース22との組み合わせとしたが、本例では、高圧ホース自体に軸強化処理を施したものを伝達部20とする。
軸強化処理としては、例えば高圧ホースの層内に線材や網体などの補強材を配設する方法、高強度樹脂製とする方法などがある。
この場合、構造が簡素化するため製造コストが低廉になる効果に加え、削孔時の操作が容易になるという効果を奏する。
[Example using shaft reinforced hose]
In the first embodiment, the transmission unit 20 is a combination of the extrapolation material 21 and the high-pressure hose 22, but in this example, the high-pressure hose itself subjected to the shaft strengthening process is used as the transmission unit 20.
Examples of the shaft strengthening treatment include a method of arranging a reinforcing material such as a wire or a net in the layer of the high-pressure hose, a method of making a high-strength resin, and the like.
In this case, in addition to the effect of reducing the manufacturing cost because the structure is simplified, there is an effect that the operation at the time of drilling becomes easy.

[外挿材にライニング部を設けた実施例]
実施例1の外挿材21にライニング部23を設けた他の実施例を説明する(図3)。
ライニング部23は、外挿材21をスプリングコイルとした場合において、外挿材21の外周面の少なくとも一部を被覆する部材である。例えばスプリングコイルの外周面にゴム材を塗着して、これをライニング部23とすることができる。
被削孔体Aの孔内において、削孔の過程で粉砕された粗骨材などは、ヘッド11後方から噴射する高圧水で孔外方向へ吹き飛ばされる。これらの破砕屑が外挿材21のコイル間の隙間や、ガイド材40と外挿材21との間に挟まると、外挿材21の形状が歪んだり、ガイド材40内で外挿材20の方向が変化したりして、削孔方向D1が一方向に偏る恐れがある。
これに対し、外挿材21の外周面をライニング部23で被覆することで、破砕屑がコイル間の隙間や、ガイド材40と外挿材21の間に詰まることを防止し、削孔方向D1の偏心を回避することができる。
[Example in which lining part is provided on extrapolated material]
The other Example which provided the lining part 23 in the extrapolation material 21 of Example 1 is described (FIG. 3).
The lining portion 23 is a member that covers at least a part of the outer peripheral surface of the extrapolated material 21 when the extrapolated material 21 is a spring coil. For example, a rubber material can be applied to the outer peripheral surface of the spring coil to form the lining portion 23.
In the hole of the hole A to be cut, coarse aggregates pulverized in the drilling process are blown away by the high-pressure water sprayed from the back of the head 11 in the hole outward direction. If these crushing debris is sandwiched between the gaps between the coils of the extrapolated material 21 or between the guide material 40 and the extrapolated material 21, the shape of the extrapolated material 21 is distorted, or the extrapolated material 20 within the guide material 40. Or the direction of drilling D1 may be biased in one direction.
On the other hand, by covering the outer peripheral surface of the extrapolated material 21 with the lining portion 23, crushing waste is prevented from clogging between the coils and between the guide material 40 and the extrapolated material 21. The eccentricity of D1 can be avoided.

[被削孔体外で屈曲させた実施例]
実施例1では、伝達部20を被削孔体Aの内部で屈曲させたが、本例では被削孔体Aの壁面前面で屈曲させて削孔する(図4)。
すなわち、壁面平行方向を送り出し方向D2とし、壁面直角方向を削孔方向D1とする。
例えば、被削孔体Aの前面に構造物が存在し、削孔部10を壁面直角方向に送り出す十分な空間を確保できない場合、削孔装置1をこのように配置することで、伝達部20を壁面平行方向に送り出し、被削孔材Aに壁面直角方向に削孔することができる。また、同様に、天井面や床面へ削孔することもできる。
[Example of bending outside the hole to be cut]
In the first embodiment, the transmitting portion 20 is bent inside the cut hole A, but in this example, the hole is bent by bending the front surface of the cut hole A (FIG. 4).
That is, the parallel direction of the wall surface is defined as the feeding direction D2, and the direction perpendicular to the wall surface is defined as the drilling direction D1.
For example, when there is a structure on the front surface of the drilled hole A and a sufficient space for feeding the drilled portion 10 in the direction perpendicular to the wall surface cannot be secured, the transmitting device 20 is arranged by arranging the drilling device 1 in this way. Can be fed in the direction parallel to the wall surface, and the hole A can be drilled in the direction perpendicular to the wall surface. Similarly, holes can be drilled into the ceiling surface or floor surface.

[ガイド管と接続管を孔内で接続する実施例]
実施例1では、ガイド材40と接続管41とを連結した状態でコア孔H1に差し入れた。しかし、コア孔H1の内径が十分でないと、接続管41の外周がコア孔H1の孔口に干渉し、ガイド管40を螺着したままでは接続管41を孔内に差し入れることができない場合がある。
この場合にはまず、削孔部10と伝達部20を内挿した状態のガイド材40を、コア孔H1の内奥部まで送り出す。つづいて、削孔部10でコア孔H1の内奥部を平行孔H2方向に切削・拡幅して、コア孔H1の内奥部にガイド材40と接続管41とを接続可能な空間を確保する。
つづいて、伝達部20に外挿した接続管41を伝達部20に沿ってガイド材40方向へ送り出し、コア孔H1内で両者を接続する。
なお、ガイド材40を送り出す前に、あらかじめコア孔H1の内奥部を拡幅して接続用の空間を設けておいても良い。
その後の工程は実施例1と同様である。
[Example of connecting guide pipe and connecting pipe in the hole]
In Example 1, the guide member 40 and the connecting pipe 41 were connected to each other and inserted into the core hole H1. However, when the inner diameter of the core hole H1 is not sufficient, the outer periphery of the connection pipe 41 interferes with the hole of the core hole H1, and the connection pipe 41 cannot be inserted into the hole with the guide pipe 40 screwed. There is.
In this case, first, the guide material 40 in a state where the hole drilling portion 10 and the transmission portion 20 are inserted is sent out to the inner back portion of the core hole H1.
