Description

本発明は、マンションなどの集合住宅、あるいはオフィスビルにおける給排水管などの改修工事（配管の引替え工事）等に適した穿孔装置に関するものである。   The present invention relates to a perforating apparatus suitable for a renovation work (pipe replacement work) such as a water supply / drain pipe in an apartment building such as an apartment or an office building.

マンションなどの集合住宅、あるいはオフィスビルのうち築年数が経っているものでは、例えば給水配管の内部に錆が生じるなど老朽化が進み、生活用水の供給に支障が生じているものがある。このような建物では、必要に応じて給水配管を塩ビ管などの耐腐食性の高い配管に交換することが要求され、この場合、壁面内部の配管をそっくり引替えると、壁面の解体撤去およびその復旧が必要となり工期も費用も嵩むこととなる。   Among apartment buildings such as condominiums or office buildings that are aged, there are some that have deteriorated due to, for example, rusting inside the water supply pipes, which hinders the supply of water for daily use. In such a building, it is required to replace the water supply pipe with a highly corrosion-resistant pipe such as a vinyl chloride pipe if necessary.In this case, if the pipe inside the wall is completely replaced, the wall will be dismantled and removed. Restoration is required, and the construction period and costs increase.

そのため、最近では、旧配管を残したまま別途室内に新たな配管を設け、この配管とその近辺全体を覆材で覆って配管が壁面内部に設けられているように擬装することにより、改修工事の低廉化と工期短縮を図ることが行われている。本願出願人もこの種の工法に関する出願を行っている（特願２００４−３８１７１９）。   Therefore, recently, refurbishment work was done by installing a new pipe in the room while leaving the old pipe, and disguising this pipe and its entire vicinity with a covering material so that the pipe is installed inside the wall. To reduce costs and shorten the construction period. The present applicant has also filed an application regarding this type of construction method (Japanese Patent Application No. 2004-381719).

配管を覆材で覆う上記の工法では、居住者の違和感をより良く払拭し得るように、天井近傍の壁面に沿って配管を設け、この配管を廻り縁風の覆材で覆うことが考えられる。この場合、例えば隣室に配管を通すことが求められると、壁面の天井近くに穿孔を設けて配管を通すことになるが、ここに次のような課題がある。   In the above construction method of covering the piping with the covering material, it is conceivable that the piping is provided along the wall surface near the ceiling so that the resident's uncomfortable feeling can be better wiped off, and this piping is covered with the covering material of the surrounding wind. . In this case, for example, if it is required to pass a pipe through the adjacent room, a perforation is provided near the ceiling of the wall surface and the pipe passes through. However, there are the following problems.

すなわち、例えば壁面がコンクリート壁である場合には、コンクリートドリルやコアドリル等のドリルを使って穿孔作業を行うが、この場合、作業者がドリルを担いだ状態で、しかも天井近傍の狭いスペースでドリルを水平に保ちつつ穿孔作業を行うことは極めて困難である。そこで、実際にはコンクリート壁にアンカーボルトを打ち込むことによりこのボルトを使ってドリルを天井近傍に固定して作業を行うことになる。   That is, for example, when the wall surface is a concrete wall, drilling is performed using a drill such as a concrete drill or a core drill. In this case, the drill is carried out in a narrow space near the ceiling with the operator carrying the drill. It is extremely difficult to perform the drilling operation while keeping the horizontal position. Therefore, in practice, an anchor bolt is driven into the concrete wall, and the bolt is used to fix the drill near the ceiling.

しかしながら、コンクリート壁にアンカーボルトを打ち込むとなると、その部分の修復作業が必要となり、穿孔そのもものは小さくても壁面の広い範囲に亘って修復作業が要求されるケースが出てくる。従って、この点を改善することが望まれる。   However, when anchor bolts are driven into a concrete wall, a repair work for that portion is required, and there are cases where the repair work is required over a wide range of wall surfaces even if the perforation itself is small. Therefore, it is desirable to improve this point.

本発明は、上記の事情に鑑みてなされたものであって、アンカーボルトを壁面に打ち込むことなく天井近傍の壁面に容易に、かつ適切に穿孔を設けることができるアンカーレス穿孔装置を提供することを目的とする。   The present invention has been made in view of the above circumstances, and provides an anchorless drilling device capable of easily and appropriately providing a drill in a wall near the ceiling without driving an anchor bolt into the wall. With the goal.

上記課題を解決するために、本発明の穿孔装置は、天井近傍の側壁に対して穿孔を設けるための穿孔装置であって、ドリルを先端に備えたドリルユニットと、ドリルが横向きとなる姿勢で前記ドリルユニットを支持するフレームと、このフレームに対して前記ドリルユニットを相対的にドリル軸方向にスライドさせるスライド機構と、ドリルユニットの姿勢を保った状態で前記フレームを昇降させる空気圧昇降装置と、前記フレームにおける前記ドリルユニットより上側の部分に設けられ、天井面に圧接されることにより前記天井面との摩擦力により前記フレームを天井面に対して横方向に拘束する圧接部とを備えているものである（請求項１）。   In order to solve the above problems, a drilling device according to the present invention is a drilling device for drilling a side wall in the vicinity of a ceiling, and is provided with a drill unit having a drill at a tip thereof and a posture in which the drill is oriented sideways. A frame that supports the drill unit, a slide mechanism that slides the drill unit relative to the frame in the direction of the drill axis, and a pneumatic lifting device that lifts and lowers the frame while maintaining the posture of the drill unit; A pressure contact portion provided on a portion of the frame above the drill unit and being pressed against the ceiling surface to restrain the frame laterally with respect to the ceiling surface by a frictional force with the ceiling surface; (Claim 1).

この穿孔装置により側壁に穿孔を設けるには、ドリルユニットを支持したフレームを空気圧昇降装置により上昇させて圧接部を天井面に圧接させ、これにより天井と床との間に穿孔装置を突っ張った状態で固定する。そして、この状態でドリルを駆動してドリルユニットをフレームに対して側壁側にスライドさせ、これによりドリル先端を側壁に押付けて穿孔を形成する。   In order to provide perforation on the side wall by this perforating device, the frame supporting the drill unit is raised by the pneumatic lifting device and the press contact portion is pressed against the ceiling surface, and thus the perforating device is stretched between the ceiling and the floor. Secure with. In this state, the drill is driven to slide the drill unit toward the side wall with respect to the frame, thereby pressing the tip of the drill against the side wall to form a hole.

上記の穿孔装置においては、ドリル先端部分に冷却水を供給する給水手段と、穿孔部分からの流水を受ける筒状の水受部材と、水受部材内の水を排水する排水管とが設けられ、前記ドリルの先端がこの水受部材に挿入されてなり、前記水受部材が、前記フレームに対してドリル軸方向にスライド可能に支持され、かつ付勢手段により前記フレームによりも側壁側に突出する突出位置に付勢された構成となっているのが好ましい（請求項２）。   In the above drilling device, a water supply means for supplying cooling water to the drill tip portion, a cylindrical water receiving member for receiving flowing water from the drilling portion, and a drain pipe for draining water in the water receiving member are provided. The tip of the drill is inserted into the water receiving member, and the water receiving member is supported so as to be slidable in the drill axial direction with respect to the frame, and protrudes toward the side wall from the frame by the biasing means. It is preferable that the structure is biased to the protruding position.

この穿孔装置では、水受部材の先端を側壁に当接させ、この状態でドリル先端に対して冷却水を供給しながら穿孔作業を行う。これによると、ドリル先端に供給されて穿孔から流出する水が水受部材により受水されつつ排水管を通じて排出される。この際、付勢手段による付勢力に抗して水受部材を多少フレーム側に押し戻した状態で穿孔装置を固定しておくと、水受部材が側壁に圧接された状態となり、その結果、側壁と水受部材との当接部分からの漏水が確実に防止される。   In this drilling device, the tip of the water receiving member is brought into contact with the side wall, and in this state, the drilling operation is performed while supplying cooling water to the tip of the drill. According to this, the water that is supplied to the tip of the drill and flows out from the perforation is discharged through the drain pipe while being received by the water receiving member. At this time, if the perforating device is fixed in a state where the water receiving member is pushed back to the frame side somewhat against the urging force by the urging means, the water receiving member is pressed against the side wall, and as a result, the side wall Water leakage from the contact portion between the water receiving member and the water receiving member is reliably prevented.

なお、上記の穿孔装置において、前記ドリルユニットが、前記ドリルとしてダイヤモンドコアビットを備えたものであれば（請求項３）、特に、コンクリート壁の穿孔作業に有用なものとなる。   In the above drilling apparatus, if the drill unit is provided with a diamond core bit as the drill (Claim 3), it is particularly useful for drilling a concrete wall.

本発明の穿孔装置によると、空気圧昇降装置によりフレームを上昇させて天井面に圧接させ、この状態でドリルユニットを側壁側にスライドさせるだけで容易に側壁に穿孔を設けることができる。従って、従来のようにコンクリート壁にアンカーボルトを打ち込むことなく天井近傍の側壁に対して好適に穿孔を設けることができる。そして、アンカーボルトを打ち込むことなくこの種の穿孔作業を行えるようになる結果、例えば配管改修工事などの工期を効果的に短縮でき、また工事費用の低廉化を図ることができる。   According to the perforating apparatus of the present invention, it is possible to easily perforate the side wall simply by lifting the frame with the pneumatic lifting device to press the frame against the ceiling surface and sliding the drill unit to the side wall in this state. Therefore, the perforation can be suitably provided in the side wall near the ceiling without driving anchor bolts into the concrete wall as in the prior art. As a result of this kind of drilling work being performed without driving anchor bolts, it is possible to effectively shorten the construction period of, for example, pipe repair work, and to reduce the construction cost.

本発明の実施形態について図面を用いて説明する。   Embodiments of the present invention will be described with reference to the drawings.

図１は本発明に係る穿孔装置を側面図で示している。同図に示すように、穿孔装置１０は、脚１２ａを具備した上下方向に伸縮可能なエアシリンダ１２（空気圧昇降装置）を有し、このエアシリンダ１２の先端に、ドリルユニット１６を内蔵した箱形のフレーム１４を備えた構成となっている。   FIG. 1 shows a side view of a drilling device according to the invention. As shown in the figure, the drilling device 10 has an air cylinder 12 (pneumatic lifting device) that is provided with legs 12 a and can be expanded and contracted in the vertical direction, and a box in which a drill unit 16 is built in the tip of the air cylinder 12. The structure is provided with a shaped frame 14.

エアシリンダ１２は、エアホース１３および図外の切換バルブ等を介してコンプレッサに接続されており、前記切換バルブの操作により無段階に伸縮可能に構成されている。   The air cylinder 12 is connected to the compressor via an air hose 13 and a switching valve (not shown), and is configured to be able to expand and contract steplessly by operating the switching valve.

フレーム１４は、中空で側面が開口した構造を有し、水平方向（同図では左右方向）に細長で、その長手方向の略中間部分を上記エアシリンダ１２により支持されている。このフレーム１４の上面には、その全面に亘ってゴムシートが接着されることにより天井面に対する圧接部１４ａが設けられている。   The frame 14 has a hollow structure with an open side surface, is elongated in the horizontal direction (left-right direction in the figure), and is supported by the air cylinder 12 at a substantially intermediate portion in the longitudinal direction. On the upper surface of the frame 14, a pressure contact portion 14a for the ceiling surface is provided by bonding a rubber sheet over the entire surface.

ドリルユニット１６は、駆動用のモータ等を有するボディ１７ａと、その出力軸に固定されるコアビット１７ｂと、図外のコントローラ等とを有しており、当実施形態では、コアビット１７ｂとしてダイヤモンドコアビットが用いられている。   The drill unit 16 includes a body 17a having a driving motor and the like, a core bit 17b fixed to the output shaft thereof, a controller and the like (not shown), and in this embodiment, a diamond core bit is used as the core bit 17b. It is used.

ドリルユニット１６は、同図に示すように、横向きの姿勢でフレーム１４内に配設されており、前記ボディ１７ａの部分がスライド機構に連結されることにより、フレーム１４に対してドリル軸方向に相対的にスライド可能に支持されている。   As shown in the figure, the drill unit 16 is disposed in the frame 14 in a lateral orientation, and the body 17a is connected to the slide mechanism so that the drill unit 16 extends in the drill axis direction with respect to the frame 14. It is relatively slidably supported.

スライド機構は、フレーム１４の内底面に固定されるラック２２と、このラック２２に噛合するピニオン（図示省略）を具備し、操作ハンドル２４の回転操作に伴い前記ラック２２に沿って移動するスライダ２０とから構成されており、ドリルユニット１６の前記ボディ１７ａがこのスライダ２０に固定されている。この構成により、前記操作ハンドル２４を回転操作すると、これに応じてスライダ２０と一体にドリルユニット１６がドリル軸方向に進退移動するようになっている。   The slide mechanism includes a rack 22 fixed to the inner bottom surface of the frame 14 and a pinion (not shown) that meshes with the rack 22. The slider 20 moves along the rack 22 as the operation handle 24 rotates. The body 17 a of the drill unit 16 is fixed to the slider 20. With this configuration, when the operation handle 24 is rotated, the drill unit 16 is moved forward and backward in the drill axis direction integrally with the slider 20 according to the rotation operation.

ドリルユニット１６には給水ホース１８が接続されており、この給水ホース１８、出力軸およびコアビット１７ｂの内部を通じて該ドリル先端に冷却水が供給されるようになっている。給水ホース１８は、図外の開閉バルブおよびポンプ等を介して給水タンクに接続されており、開閉バルブの操作に応じて給水と断水とが切換えられるようになっている。   A water supply hose 18 is connected to the drill unit 16, and cooling water is supplied to the drill tip through the water supply hose 18, the output shaft, and the core bit 17b. The water supply hose 18 is connected to a water supply tank via an open / close valve and a pump (not shown) so that water supply and water cutoff can be switched according to the operation of the open / close valve.

なお、上記フレーム１４には、穿孔作業時に穿孔部分から流出する冷却水（使用済みの冷却水）を受ける筒状の水受ハウジング３０（水受部材）が設けられおり、この水受ハウジング３０に前記コアビット１７ｂの先端が挿入されている。   The frame 14 is provided with a cylindrical water receiving housing 30 (water receiving member) that receives cooling water (used cooling water) that flows out from the drilled portion during the drilling operation. The tip of the core bit 17b is inserted.

この水受ハウジング３０は、同図に示すように、フレーム１４の内天井に設けられるレール３４にアーム３２を介してスライド可能に装着されている。レール３４は前記ラック２２と平行に設けられており、これによって水受ハウジング３０が、その先端がフレーム１４の端面から突出する突出位置（図示の位置）とこの位置からフレーム側に後退した位置とに亘ってフレーム１４に対して相対的にドリル軸方向にスライド可能に設けられている。なお、フレーム１４のうちドリル先端側の端部と前記アーム３２との間には引張コイルバネ３６が装着されており、この引張コイルバネ３６の弾性力により水受ハウジング３０が前記突出位置に向かって付勢されるようになっている。   As shown in the figure, the water receiving housing 30 is slidably attached to a rail 34 provided on the inner ceiling of the frame 14 via an arm 32. The rail 34 is provided in parallel with the rack 22, whereby the water receiving housing 30 has a protruding position (a position shown in the drawing) in which the tip protrudes from the end surface of the frame 14 and a position retracted from this position to the frame side. It is slidable relative to the frame 14 in the drill axis direction. A tension coil spring 36 is mounted between the end of the drill tip side of the frame 14 and the arm 32, and the water receiving housing 30 is attached toward the protruding position by the elastic force of the tension coil spring 36. Has come to be.

また、水受ハウジング３０の先端面（同図では左端）には、その全周に亘ってゴムパッキン３０ａが装着されており、水受ハウジング３０を側壁に圧接するとこのゴムパッキン３０ａにより水受ハウジング３０と側壁の間がシールされるようになっている。   Further, a rubber packing 30a is attached to the front end surface (the left end in the figure) of the water receiving housing 30 over the entire circumference. When the water receiving housing 30 is pressed against the side wall, the water receiving housing 30 is pressed by the rubber packing 30a. Between 30 and the side wall is sealed.

水受ハウジング３０には、さらにその下面に排水ホース３８（排水管）が接続されており、水受ハウジング３０内に溜まった使用済みの冷却水がこの排水ホース３８を通じて排水されるようになっている。   A drainage hose 38 (drainage pipe) is further connected to the lower surface of the water receiving housing 30, and used cooling water accumulated in the water receiving housing 30 is drained through the drainage hose 38. Yes.

次に、この穿孔装置１０を用いた穿孔作業の手順について図２を用いて説明する。   Next, the procedure of drilling work using this drilling apparatus 10 will be described with reference to FIG.

前準備として、ドリルユニット１６をフレーム１４内に引き込み、コアビット１７ｂの先端をフレーム１４の内側まで後退させておく。なお、エアシリンダ１２はある程度縮小した状態にしておく。   As preparation, the drill unit 16 is pulled into the frame 14 and the tip of the core bit 17b is retracted to the inside of the frame 14. The air cylinder 12 is kept in a state of being reduced to some extent.

そして、まず穿孔を設けるべき側壁Ｗａにコアビット１７ｂ先端が対向するようにフレーム１４の向きを調整し、さらに水受ハウジング３０の先端と側壁Ｗａとの間に若干隙間がある距離まで穿孔装置１０全体を側壁Ｗａに近づけ、この状態で、エアシリンダ１２を伸長させてフレーム１４を上昇させる。この際、図２（ａ）に示すように、天井Ｒｏに対してフレーム１４の圧接部１４ａが接触するか、あるいは圧接部１４ａと天井Ｒｏとの間に僅かに隙間が残る程度の高さまでフレーム１４を上昇させる。   First, the orientation of the frame 14 is adjusted so that the end of the core bit 17b faces the side wall Wa where the perforation is to be provided, and the entire perforation apparatus 10 is further moved to a distance where there is a slight gap between the front end of the water receiving housing 30 and the side wall Wa. In this state, the air cylinder 12 is extended to raise the frame 14. At this time, as shown in FIG. 2A, the frame 14 is touched by the pressure contact portion 14a of the frame 14 with respect to the ceiling Ro, or the height is such that a slight gap remains between the pressure contact portion 14a and the ceiling Ro. 14 is raised.

次いで、穿孔装置１０全体をさらに側壁Ｗａ側に近づける。具体的には、図２（ｂ）に示すように、水受ハウジング３０の先端が側壁Ｗａに当接し、かつこの水受ハウジング３０が引張コイルバネ３６の弾性力に抗して適度にフレーム１４内に押し戻される位置まで穿孔装置１０全体を側壁Ｗａに近づける。この際、穿孔装置１０は、上記の通り天井Ｒｏに対して圧接部１４ａが接触するか、あるいは圧接部１４ａと天井Ｒｏとの間に僅かに隙間が残る高さにフレーム１４があるため簡単に側壁Ｗａに近づけることができる。   Next, the entire punching device 10 is further moved closer to the side wall Wa. Specifically, as shown in FIG. 2 (b), the tip of the water receiving housing 30 abuts against the side wall Wa, and the water receiving housing 30 is appropriately within the frame 14 against the elastic force of the tension coil spring 36. The entire punching device 10 is brought close to the side wall Wa until it is pushed back to the side. At this time, the punching device 10 is easy because the frame 14 is at such a height that the press contact portion 14a contacts the ceiling Ro as described above or a slight gap is left between the press contact portion 14a and the ceiling Ro. It can be brought close to the side wall Wa.

この作業が完了したら、エアシリンダ１２をさらに伸長させて圧接部１４ａを天井Ｒｏに圧接させ、これにより穿孔装置１０を天井Ｒｏと床Ｆｌとの間に突っ張った状態で固定する。   When this operation is completed, the air cylinder 12 is further extended to bring the pressure contact portion 14a into pressure contact with the ceiling Ro, whereby the perforating apparatus 10 is fixed in a stretched state between the ceiling Ro and the floor Fl.

そして、この状態でコアビット１７ｂを回転駆動し、前記操作ハンドル２４の操作に伴い、図２（ｃ）に示すように、フレーム１４に対してドリルユニット１６を相対的に移動させることにより側壁Ｗａに向かって前進させ、これによりコアビット１７ｂ先端を側壁Ｗａに押付ける。また、開閉バルブを開くことにより給水ホース１８を通じてコアビット１７ｂ先端に冷却水の供給を開始する。これによりコアドリル１７ｂにより側壁Ｗａに穿孔を形成する。   In this state, the core bit 17b is rotationally driven, and the drill unit 16 is moved relative to the frame 14 as shown in FIG. The tip of the core bit 17b is thereby pressed against the side wall Wa. Further, the supply of cooling water to the tip of the core bit 17b is started through the water supply hose 18 by opening the open / close valve. Thereby, the core drill 17b forms a hole in the side wall Wa.

なお、穿孔作業中は、コアビット１７ｂが側壁Ｗａに押付けられることによりその反力がフレーム１４に作用するが、上記の通りフレーム１４のうちゴムシートからなる上記圧接部１４ａが天井Ｒｏに圧接されている結果、天井面とこの圧接部１４ａとの摩擦力により上記反力が確実に受けられる。そのためドリルユニット１６を前進させることによりコアビット１７ｂを確実に側壁Ｗａに切り込むことができる。   During the drilling operation, the core bit 17b is pressed against the side wall Wa, so that the reaction force acts on the frame 14. As described above, the pressure contact portion 14a made of a rubber sheet in the frame 14 is pressed against the ceiling Ro. As a result, the reaction force is reliably received by the frictional force between the ceiling surface and the pressure contact portion 14a. Therefore, the core bit 17b can be reliably cut into the side wall Wa by moving the drill unit 16 forward.

また、穿孔作業中は、上記のようにコアビット１７ｂ先端に冷却水が供給されるが、使用後の冷却水は穿孔部分から水受ハウジング３０に流出し、この水受ハウジング３０により集水されながら排水ホース３８を通じて排水されることとなる。この際、上記のように水受ハウジング３０が引張コイルバネ３６の弾性力に抗して適度にフレーム１４内に押し戻されている結果、水受ハウジング３０は、引張コイルバネ３６の弾性力によって側壁Ｗａに圧接された状態となっている。従って、水受ハウジング３０と側壁Ｗａとの間がゴムパッキン３０ａにより完全にシールされ、その結果、側壁Ｗａに対する水受ハウジング３０の当接部分からの漏水が確実に防止されることとなる。   Further, during the drilling operation, the cooling water is supplied to the tip of the core bit 17b as described above, and the used cooling water flows out from the drilled portion to the water receiving housing 30 and is collected by the water receiving housing 30. The water is drained through the drain hose 38. At this time, as a result of the water receiving housing 30 being appropriately pushed back into the frame 14 against the elastic force of the tension coil spring 36 as described above, the water receiving housing 30 is applied to the side wall Wa by the elastic force of the tension coil spring 36. It is in a pressed state. Therefore, the space between the water receiving housing 30 and the side wall Wa is completely sealed by the rubber packing 30a, and as a result, water leakage from the contact portion of the water receiving housing 30 with respect to the side wall Wa is surely prevented.

こうして側壁Ｗａに所望の穿孔が形成されると、冷却水の供給を停止させるとともにドリルユニット１６をフレーム１４内に後退させる。そして、上記と逆の手順でフレーム１４を天井Ｒｏから引き離す。これにより一連の穿孔作業が終了する。   When the desired perforations are thus formed in the side wall Wa, the supply of cooling water is stopped and the drill unit 16 is retracted into the frame 14. Then, the frame 14 is pulled away from the ceiling Ro in the reverse procedure to the above. This completes a series of drilling operations.

以上のように、この穿孔装置１０によると、エアシリンダ１２の作動により穿孔装置１０を天井Ｒｏと床Ｆｌとの間に突っ張った状態で固定し、コアビット１７ｂを駆動してドリルユニット１６を側壁Ｗａに向かって前進させるだけで、天井近傍の側壁Ｗａに適切に穿孔を形成することができるため、従来のようにコンクリート壁にアンカーボルトを打ち込んでドリルユニットを固定するといった作業が一切不要となる。   As described above, according to this drilling device 10, the air cylinder 12 is operated to fix the drilling device 10 while being stretched between the ceiling Ro and the floor Fl, and the core bit 17b is driven to attach the drill unit 16 to the side wall Wa. Since the perforation can be appropriately formed in the side wall Wa in the vicinity of the ceiling simply by moving forward, the work of driving anchor bolts into the concrete wall and fixing the drill unit is unnecessary at all.

従って、アンカーボルトを打ち込む従来の穿孔作業のように、作業後に側壁Ｗａの広い範囲に亘って修復作業を行う必要が無くなり、その結果、例えば配管改修工事等においてその工期を短縮するとともに工費の低廉化を図ることができるようなる。   Therefore, it is not necessary to perform repair work over a wide range of the side wall Wa after the work as in the conventional drilling work in which the anchor bolt is driven. As a result, for example, in the pipe repair work, the construction period is shortened and the construction cost is low. Can be achieved.

なお、上述した穿孔装置１０は、本発明に係る穿孔装置の実施形態の一例であって、その具体的な構成は、本発明の要旨を逸脱しない範囲で適宜変更可能である。   The above-described perforating apparatus 10 is an example of an embodiment of the perforating apparatus according to the present invention, and a specific configuration thereof can be appropriately changed without departing from the gist of the present invention.

例えば、実施形態では、ドリルとしてコアビット１７ｂ（ダイヤモンドコアビット）を備えたドリルユニット１６を用いているが、勿論、ドリルの種類や形状等はこれ以外のものであってもよく、穿孔を設ける側壁Ｗａに応じて適宜選定すればよい。   For example, in the embodiment, the drill unit 16 provided with the core bit 17b (diamond core bit) is used as a drill. However, the drill may have other types, shapes, and the like, and the side wall Wa where the drill is provided. Appropriate selection may be made according to the above.

また、実施形態では、操作ハンドル２４のハンドル装置によりドリルユニット１６を切込み送りするようにしているが、例えばモータを駆動源として自動的にドリルユニット１６を送り駆動し得るように構成してもよい。この場合、送り速度の調整機能を設けるのが好ましい。   In the embodiment, the drill unit 16 is cut and fed by the handle device of the operation handle 24.
