Definitions

  • the invention relates to a method for filling depths Manholes, especially mine shafts, with hardening material, preferably hydraulically curing material, which is a binder, preferably cement, an aggregate, an additive and water having.
  • hardening material preferably hydraulically curing material, which is a binder, preferably cement, an aggregate, an additive and water having.
  • This hardening material is applied above ground using suitable systems manufactured, mostly semi-mobile systems are used on site. Basically ready-mixed concrete is also an option.
  • a method is known in which the ready-mixed, hardening mixture Material is poured into a pipeline above ground, which briefly below or ends above the level of the material already filled in the shaft and the higher the level rises, the more it is pulled up.
  • the Filling takes place with a pipeline, i.e. a filling pipe, because with the large depths to be filled in free fall a separation of the components of the hardening material occurs.
  • Under a "deep" shaft a Understood shaft that is at least 30 or 40 meters deep. Usual Mine shafts, for example, are 1,000 meters deep.
  • Free fall is hindered by the pipeline, even if at the beginning, the first time the tube is filled, the condition of a free fall does not is to avoid. Only when the pipe is close to its upper, surface end is filled with the hardening material, there is a state that now the flow rate can be regulated by the pipe more or is raised less.
  • an aggregate is used used, which has a grain size less than 2 mm.
  • the additive is also under this grain size. Because of the small grains used
  • the aggregate is also separated in free fall in the Mine shaft does not take place.
  • the hardening material is in the shaft filled, for example with a conveyor belt and then falls without one Pipe down freely.
  • This method also has the disadvantage that constipation and underneath can form cavities.
  • the hardening material that the Shaft walls stuck creates a starting point for that subsequent material adheres to it, so that the shaft is closed, although there is still a cavity underneath.
  • a cavity can be filled with gas, For example, fill methane, furthermore it can lead to mining damage later come.
  • the invention has for its object the method of to improve the kind mentioned at the beginning that a plug formation when filling the hardening material into the shaft is avoided.
  • this task solved in that the aggregate at least a grain size of 4 mm has and the roughest possible surface.
  • the invention is based on the following consideration:
  • the relatively coarse-grained aggregate ensures that caking cannot become too thick when it is being filled, but rather is even removed by falling and penetrating material.
  • the relatively large grains which may have a grain diameter preferably well above 4 mm, for example 16 mm or 22 mm, come into contact with the shaft walls and the deposits of the hardening material already located there and repeatedly grind off the material when it falls down, tearing off so it down with.
  • the coarse grains prevent noticeable deposits from forming on the walls, and the risk of clogging is avoided in this way.
  • the relatively rough surface of the aggregates is important.
  • aggregates act like lubricant particles, they rub along with them their rough surface along the shaft walls and tear it there already baked, not yet hardened material from time to time in the Depth. In this way, manhole fillings are without constant monitoring possible.
  • the aggregate has one specific gravity that is close to, preferably equal to, the specific Weight of the ready-to-use material, without the aggregate. Under a obvious specific weight becomes a specific weight understood that the maximum weight of the specific weight of the ready-to-use material without the aggregate, preferably the difference is less than 0.5.
  • the specific weight of the material without Additive is typically between 1 and 2 grams each Cubic centimeters.
  • the aggregate also has a surface that is as rough as possible, can loosen the concrete slurry poorly from the aggregate, this also becomes one Segregation counteracted.
  • the specific weight of the aggregate can be taken through appropriate measures are influenced, for example by blowing processes or others Measures to create internal voids. If of the specific Weight of the aggregate is mentioned, so this is not an averaging understood about a large amount of aggregate, but it has to be for everyone individual granules essentially meet the condition that be concrete specific weight as close as possible to the specific weight of the Concrete porridge is. In this way, the condition for each individual grain satisfied that it falls down in air essentially as quickly as the Concrete slurry that at least partially surrounds the grain, preferably all of it envelops.
  • Cohesive materials are particularly suitable as additives.
  • the Aggregate can be made from natural and / or industrial substances (up to Limit of the LAGA Z2). These grain sizes show typically a distribution curve from 0 to 16 mm. You can do that Control grain curves, for example a particularly large amount of coarse-grained material or use a lot of fine-grained material.
  • a deep shaft 20 can also be used be filled in quickly. Since there is no risk of a plug forming and the insertion while slowly pulling up one serving for filling Pipeline is no longer required, the shaft 20 can be practically so can be filled in quickly, like the hardening material on the surface in one day Mixing system 22 manufactured and from there entered into the shaft opening 24 can be. In this way, even very deep shafts are relatively successful quickly, e.g. B. to fill in one day. This was previously the case with the Technology not possible.
  • the semi-mobile mixing plant 22 is located above ground next to the Shaft opening 24. This is ready for use by means of a conveyor belt 26 mixed, hydraulically curing material into the shaft opening 24 introduced and falls down in clumps of material 28. This can lead to caking 30 on the shaft wall. This but are always worn away by the falling material. The Introducing the hardening material goes so quickly that the caking 30 can not harden.
  • the shaft 20 is already filled to a small extent, the mirror of the filled material is marked with 32.
  • the shaft 20 is only shown schematically in the figure. It is one transverse sole 34 is drawn, the left through a wall 36 is bricked up, the sole is open on the right. In the left area is the room to the right of the wall 36 through the hardening material practically completely replenished. An approach through deposited material has already formed. in the right area of the sole 34 will be a cross section of the figure shown result in approximately triangular concrete body, the sole 34 remains to the right of it free.
  • the 1,270 kg crushed sand mix consists of 50 percent by weight of rust ash with a grain size of 0 to 16 mm and 50 percent by weight of crushed sand with the grain size 0 to 2 mm.
  • the fine-grained residue is removed under crushed sand the processing of building materials, in particular the processing of rubble without Humorous components (no soil) understood.
  • At least 20 percent by volume of the crushed sand mix are grains with a grain size above 10 mm, in particular there are 30, preferably 40 and in particular 50%, which have a larger grain diameter have than 10 mm.
