Definitions

  • the invention relates to a container for introducing and filling or partially filling cavities in underground mining and tunneling, which can be brought into a spreading position in the form of sacks and hoses with a multi-component filling material by inflating its wall from a transport.
  • Setting materials are used for filling cavities in underground mining and in tunnel construction, which are also occasionally filled into hoses or sacks and are moistened with water beforehand or only afterwards. These setting building materials are used in particular where the transfer of high pressures through the introduced building material is necessary. Cushions filled with gelling liquid are also known (DE-A-3 242 136). Wherever voids are to be filled, especially between the mountains and the expansion, in order to prevent the accumulation of gas or to prevent the cavities from enlarging by peeling, free-foamed synthetic resins are used, which are mixed together when they flow out under pressure that a foam, even if only carrying capacities, is produced.
  • the invention has for its object to provide a disposable container that can be used for filling cavities in the mining industry without additional return transporting supply units.
  • the wall encased storage containers with the filling material are arranged in the interior of the container designed as a sack, which are positioned connectable on the one hand with pressure containers containing propellant gas and on the other hand with a component mixer in the sack, the volume of the storage container being that of Sackes is dimensioned accordingly.
  • Such a container thus has an "inner life" which makes the container as such an independent device which can therefore be operated independently of other units and brought into its working position.
  • the container as such can be moved to its place of work in its space-saving transport position, the previous advantages are retained, while a return transport of separate units is advantageously completely eliminated.
  • the size of the storage container containing the two or more components is dimensioned such that the sack inflates to the extent that the shape itself dictates this. This ensures that the cavity to be filled is actually completely filled by the inserted container in order to prevent the accumulation of gas or the flaking off of the rock. It is also advantageous that the inside of the container can be transported protected by the wall, that is, it is protected against damage, the container as a whole being regarded as a disposable container.
  • the pressure vessel (s) for the propellant gas can be actuated from outside the wall.
  • a simple design provides that the valve arranged between the pressure container and the storage container is connected via a rip cord to a handle arranged beyond the wall.
  • By Operating or pulling the handle opens the valve so that the propellant gas flows from the pressure container into the storage container, which presses the resin held therein under normal pressure out of it and into the component mixer, where the two or more components are mixed and then into the interior of the container.
  • the training has the advantage that it is extremely simple and inexpensive to install.
  • the handle gives the handling miner the necessary specification of the position in which the container has to be inserted into the cavity to be filled. At the same time, he has specified the favorable location of the "inner life" so that a correct positioning is always ensured.
  • a good mixing effect in the component mixer is ensured in particular when both or more components are supplied at a correspondingly high pressure.
  • This is ensured on the one hand by holding a propellant gas with a correspondingly high pressure in the pressure containers and on the other hand according to the invention in that the closing valve assigned to the storage containers on the outlet side is designed to be adjustable to a specific opening pressure. In this way it is achieved that in any case a certain pressure must have built up in the reservoir before the closing valve opens and enables access to the component mixer.
  • the components held in the various storage containers also reach the component mixer at the same time.
  • the optimal mixing process is ensured and, at the same time, that both or more pressure vessels are emptied at the same time, with the propellant gas in the individual storage vessels maintaining such a high pressure that they can form a kind of pillar in the filled container.
  • a complete emptying of the storage container is achieved according to the invention in that the connecting lines to the component mixer are arranged on the side of the sack opposite the line receiving the pressure container.
  • the propellant gas thus flows through the storage containers in one direction, taking the individual components with them or driving them in front of them.
  • an internal, foldable support structure to the wall.
  • This support structure only becomes effective when the container is inflated and offers an additional possibility of increasing the support force of such a container.
  • the support structure is expediently designed to snap into the spread position so that correspondingly high support forces can be absorbed.
  • the type and design of the scaffolding can be used to specify a differently strong supporting scaffold for different purposes, so that an additional adaptation to the respective circumstances is possible with little effort.
  • the uniform inflation of the container is promoted by the fact that the wall consists of fabric or a limited amount of air-permeable film. This makes it possible on the one hand to create a container with a flexible wall and on the other hand to discharge the air displaced when the two- or multi-component mixture emerges in such a way that the inflation process or the filling of the volume predetermined by the container is not hindered.
  • the inflation process is further improved according to the invention in that the wall has distributed valves or valve surfaces which are designed to hold a predeterminable pressure.
  • the air volume present in the container is thus initially maintained and used to inflate the container as quickly as possible until a certain excess pressure exists, which then leads to the escape of the existing air and its replacement by foam.
  • an overall uniformly stable structure is created which fully fulfills the desired task and in particular completely fills the existing cavity, since it can adapt to the specific shape of the predetermined cavity without difficulty.
  • the invention is characterized in particular by the fact that a container is created which is particularly suitable for underground use in hard coal mining, because it fully meets the conditions prevailing there and can be used in a manner adapted to the particular application. It is particularly advantageous that the container as a whole forms a complete unit, which serves as a one-way device and makes the return transport of individual parts completely unnecessary. Surprisingly, the effectiveness of the container can be increased by the fact that the storage and pressure containers arranged in the interior of the container form an additional support structure after the emptying process, which, possibly supplemented by a support structure assigned to the wall, significantly increases the support force of the entire container.
  • each container has its own filling supply, which is kept unpressurized during transport and storage. The pressure required to expel the individual components is only supplied in a targeted manner during use, with both the containers for the components and for the propellant gas remaining in the container as a support structure, as mentioned.
  • the container 1 shown in FIG. 1 is shown in perspective in order to clarify its "inner life".
  • the container 1 is evenly filled with two-component foam, which is not shown here, and thus forms a support part which has a limited stability and is inserted and inserted, for example, into a cavity between the mountains and the track extension and which then, alone or together with other containers, fills the cavity.
  • the wall 2 of the container 1 formed here as a kind of sack 3 consists of a fabric or a film, so that the interior 4 filled with the two-component foam can also be further adapted to the respective cavity via the shape shown.
  • two storage containers 5, 6 are arranged in the example shown, which are connected on one side via the line 8 to the pressure container 7 and on the other hand to the component mixer.
  • the line 8 is closed by the valve 9 during the transport state shown in FIG. 2.
  • This valve 9 can, for example, be actuated from outside the container 1 by means of the rip cord 10 and the handle 11, i.e. be switched.
  • valve 9 When the valve 9 is actuated, compressed air or propellant gas flows through the line 8 from the pressure container 7 into the two storage containers 5, 6. If a corresponding pressure has built up in the storage containers 5, 6, the closing valves 14, 15 closing the connecting lines 16 open and both components are supplied to the component mixer 17 simultaneously and evenly. Here, the two components are mixed with one another in such a way that they then flow into the interior 4 of the sack 3 or the container 1 and fill it up with a foaming action.
  • the line 8 to the pressure vessel 7 is assigned to the lower side 18 of the storage containers 5, 6 and the connecting line 16 to the upper side 19 of the storage containers 5, 6, so that the propellant gas is guided over the length of the storage container 5, 6 and the entire amount of the stored resin is actually fed to the component mixer.
  • a support structure 20 is only indicated, for example from a crossing folding linkage, the individual rods of the support structure 20 locking in the end position so that they take on additional support forces.
  • the support structure 20 can either be assigned only to the side surfaces or also to all surfaces of the container 1, depending on how this is currently proving to be expedient.
  • the support structure 20 is arranged on the inside of the container 1 in order to facilitate transportation and to secure the unfolding of the wall 2 and thus its adaptation to the respective mountain areas.
  • Valve surfaces 21 are assigned to one side of the container 1 or more, via which a certain pressure in the container 1 is guaranteed at the beginning of the inflation process, since the air originally present therein cannot escape until a certain excess pressure prevails in the container 1.
