ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rock interfold method, according to which a hole is drilled in a rock, a radially expandable interfold rod is inserted into the hole, and the interfold rod is powered. It is inflated by a device and applies pressure to the wall soil of the hole that exceeds the breaking strength of the rock.

***により実施される襞間と掘削に伴なう欠点を避ける
ために、圧力液体により作動される機械的手段による岩
石の破壊に基く多くの方法と工具が開発されてきた。In order to avoid the drawbacks associated with interfolding and excavation carried out by blasting, many methods and tools have been developed that are based on the destruction of rocks by mechanical means operated by pressurized fluids.

によって該空気ジェットにより生じた圧力衝撃と該圧力
とにより岩石を破裂させる。From West German Patent Publication No. 1,294,305, a cutting rod operated by compressed air and inserted into a hole drilled in the rock is connected at one end to a compressed air accumulator and tensioned in the closed position by a safety pin at the other end. The tube expands radially outwards, so that it is pressed against the perforation wall, simultaneously sealing the hole and exerting pressure on the rock. When the pressure reaches a sufficiently high height, the safety cap of the valve is ruptured and an instantaneous air jet is injected from the radial hole in the pulp into the perforation, whereby the pressure shock caused by the air jet and the pressure causes the rock to explode. rupture.

された方式では行なわれない。However, this type of interosseous method caused a gap comparable to an explosion due to the sudden pressure shock generated, which caused rock fragments to be easily thrown around and the interosseous area was well controlled. It is not done by method.

ロッドが二つのくさび型ジョーとそのジョーの間を移動
するくさびを含む液圧作動機械的くさびが既に知られて
いる。液圧シリンダがくさびなジョーの間に押圧して、
ジョーにより生じた圧力が岩石を破壊する。A hydraulically actuated mechanical wedge is already known from Swedish Patent Publication No. 401,706, which comprises a wedge in which the interfold rod moves between two wedge-shaped jaws. A hydraulic cylinder presses between wedge jaws,
The pressure created by the jaws breaks the rock.
このよ５な襞間方法は穿穴の壁がでこぼこの場合、集中
力の−一りが一体のジョーと穴の壁の間に生じ、それに
より岩石が無制御に破裂するという欠点がある。This method of interfolding has the disadvantage that if the walls of the borehole are uneven, a concentrated force will be generated between the integral jaw and the wall of the borehole, thereby causing the rock to burst uncontrollably.
本発明の目的は上記の欠点を除去し、ＷｔＪの正確な制
御を可能にする方法を提供する事である。The aim of the invention is to provide a method which eliminates the above-mentioned drawbacks and allows precise control of WtJ.
この目的は襞間用ロッドが穴の中に伸縮性材料の圧力部
材を軸方向に圧縮する事により半径方向に膨張する事を
特徴とする本発明による方法で達成される。This object is achieved in a method according to the invention, characterized in that the interfold rod expands radially by axially compressing a pressure member of elastic material into the hole.

が起り、その結果岩石片が周囲に投げ出され、骨間が制
御できない状態となる。According to the invention, an interosseous method is provided in which the pressure member of the elastic member is able to adapt to the irregularities in the wall of the borehole, so that an evenly distributed pressure effect is produced in the borehole despite the irregularities. . The pressure effect results from the radial expansion of the elastic pressure member when the elastic member is gradually compressed axially in the core, so that the pressure effect can be steadily increased until the rock bursts. Therefore, a sudden explosion of too great a force occurs, with the result that pieces of rock are thrown around and the interbone becomes uncontrollable.
本発明は又上記の方法を実施する工具に関し、この工具

が容易である。The tool according to the invention is simple in construction and easy to process automatically.
次に本発明を添付の図面についてより詳細に説明する。The invention will now be explained in more detail with reference to the accompanying drawings, in which: FIG.

岩石Ｔに穿った六８の直径よりも若干小さい直径の筒状
面の筒状面を形成する。The interfold rod 1 has a cylindrical par 3 with a head 4 wider than the rod at one end, a tube 5 through which the par 3 extends slidably with a slight gap, and a head 4. Located between the tubes 5 and including a sliver-like pressure member 6 through which the pipes 5 and 3 extend. The spatula P4 forms an annular support surface 4a in contact with one end surface of the pressure member, and
The head 4, the tube 5 and the member 6 form a support surface 5a in contact with the other end face of the member. In their inoperative position, the head 4, the tube 5 and the member 6 are arranged in a cylinder having a diameter slightly smaller than the diameter of the hole 68 drilled into the rock T to be burst. form a cylindrical surface.

１３を介して液圧流体源１４に連結している。The hydraulic cylinder 2 includes, for example, a housing 9 integrally fixed to the tube 5 and a piston 10 integrally fixed to the par 3. A cylinder space 11 is connected by a pipe 12 via a conventional actuated valve 13 to a source of hydraulic fluid 14 .

ポリウレタンである。The pressure member 6 is made of a stretchable material that is deformable and whose volume remains substantially uncompressed when the member is compressed by an external force. Suitable materials are, for example, various imimetics and polyurethanes.

の包被面全体で穿孔の壁に対し密閉押圧される。Insert the extension rod 1 into the hole drilled in the rock between the bones,
Ensure that the pressure member 6 is completely located within the hole. Thereafter, hydraulic pressure is applied to the cylinder sleeper 11, which causes the piston to move upwards relative to the housing, causing the par 3 to move into the pipe 5.
Press the corresponding method against. This causes a radial compression of the pressure member between the support surfaces 4a and 5a, so that it expands radially outwards correspondingly and is pressed sealingly against the wall of the borehole with its entire envelope surface. Ru.

よりパーは伸縮性圧力部材の押圧作用によりその元の位
置に戻り、襞間用ロッドが次の穿入に挿入される状態と
なる。The pressure exerted by the radially expanding pressure increases. When the pressure exceeds the fracture strength of the rock, the rock becomes interosseous. Pressure is then released from the cylinder space, whereby the par returns to its original position under the pressing action of the elastic pressure member, ready for the interfold rod to be inserted into the next penetration.
襞間工具は構造と作動が非常に簡単であり、又伸縮性部

同様の破壊は生ぜず、襞間は正確に制御される。The interfold tool is very simple in construction and operation, and thanks to the elastic member, the pressure exerted on the rock by the interfold tool is evenly distributed over the entire wall surface of the borehole, even if it is uneven. . The force used to crease the rock is no greater than required for the fracture strength of the rock, so that explosion-like fractures do not occur, and the creases are accurately controlled.

, 2 may be attached.
流れ制御弁がないと、岩石が破裂した時、工具は破裂が

的圧力減少を引起し、従って骨間はスムースに行なわれ
る。流れ制御弁を使う時、圧力減少は他の工具に影響し
ないがその押圧力は変らないので、襞間はより大きな力
で行なわれる。Without a flow control valve, when the rock ruptures, the tool expands slightly more at the point where the rupture begins, simultaneously causing a momentary pressure reduction in the other tools, so that the interbone is smoothed out. When using a flow control valve, interfolding is performed with greater force since the pressure reduction does not affect other tools, but their pushing force remains the same.
