The device mainly comprises at the tip a backflow prevention device in the form of a check valve, a mixer and a mothering member made of elastic material as a tube section and supported in a metal sunk at the end.
It consists of a filling tube that can be constructed from different parts.

きている。注入の際に特に重要であるのは孔中に導入可
能な・やンカーともいわれる孔閉鎖部材である。Injection with plastic resins is becoming increasingly important, especially for strengthening brittle debris and loose rock in coal mines. Of particular importance during injection is a hole closing member, also called an anchor, which can be introduced into the hole.
従来技術

に挙げた機種の使い捨て管状孔開鎖部材はすでに公知で
あり、該部材は孔の任意の位置に配置することを可能と
し、機能を有する逆流防止装置及び流出防止装置を備え
ていて、かつ該管部分の内部で混合を可能とする。PRIOR ART According to DE 29 03 137, a disposable tubular hole-opening chain element of the type mentioned at the outset is already known, which element can be placed in any position in the hole and has a function of backflow. A prevention device and a spill prevention device are provided and mixing is possible inside the tube section.

、これによりよυ大きな断面を有する範囲での孔の閉鎖
もしくは・ぞンキンの実施には不十分であるということ
である。A major disadvantage of such disposable hole closures is that, due to the fixation and locking elements used, they can only be used in limited holes, i.e. holes with a uniform cross-section. This means that it is not sufficient to close holes or carry out inspections in areas with large cross-sections.

孔中に導入した後、まだ相応する分解及び延びを有さな
い区域、すなわち安全性が過度におびやかされている範
囲において、例えば打ち込みねじにより支承しなければ
ならないということである。Another important drawback of the hole closing elements used hitherto is with regard to the necessary safety when introducing the closing element, which, after introducing the hole closing element into the borehole, is located in an area which does not yet have a corresponding disintegration and elongation, i.e. To the extent that safety is unduly endangered, this means that mounting, for example by means of drive screws, must be provided.

えがもはや必要でないような改良点を有している。SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a pore closing element for injecting a medium suitable for strengthening rocks, which pore closure element is particularly suitable for the purpose of strengthening rocks. It has the advantage that it can be held sufficiently tightly in the cross-section, and at the same time has the advantage in terms of safety that mechanical support by hand or by screws is no longer necessary.

成されていることにより解決する。Means for solving the problem According to the invention, the filling pipe additionally has a valve in the region surrounded by the filling element, and the filling pipe is not configured to allow injection. The solution is that these valves are constructed in a self-supporting and closing manner depending on the pressure difference created by these valves.

つ孔を閉鎖するように調節可能である。The non-return valve at the tip of the hole closing member, that is, facing the deepest part of the hole, was used to ensure that the plastic resin was first placed in the area of the puncture member when press-fitting the plastic resin through the filling tube. It is distributed via a valve into an intermediate chamber between the filling tube and the packing member, the latter being supported as a self-inflating member against the bore wall and adjustable to close the bore.

あシ、かつ孔壁に・ぐソキン部材の相応する接触におい
て逆流が更なる注入工程を妨害することもない。Within the scope of the invention, it is advantageous for the valve, which is designed as a check valve, to consist of at least one opening in the filling tube that is surrounded by an annular collar. In this way, an unhindered filling and expansion of the punching member is possible, and no backflow can interfere with the further injection process in the corresponding contact of the punching member with the hole wall.

備えられているのが特に有利である。The metal sac surrounding the packing member at its end is constructed as a uniformly spaced annular sleeve which can be screwed onto the filling tube, the height of the metal sac which loosely takes up each packing member being the height of the receiving part of the packing member. It is particularly advantageous to be provided for.

の他の廂利な実施は従属請求項に記載されている。Is the containment A? This allows for wide and large expansion of the locking member as well as adaptation to undefined hole cross-sections. In order to ensure that a packing member made of a flexible material, for example rubber, is liable to break during expansion and subsequent ejection from the sack, the metal sack according to the invention has a length of at least a partial length. The thrust is configured in the direction so that the flexibility accommodates the inflation pressure. , other advantageous implementations of the invention are described in the dependent claims.

面に使用することができるということにある。The technical inventive step of the present invention, as already mentioned, is that it is no longer necessary to mechanically support the hole closure member, especially in areas that are not sufficiently secure, thus the safety of persons is significantly increased and is simple. The advantage lies in the fact that it can be used in an economical manner with unlimited hole cross-sections.
