Definitions

  • the invention relates to a device for influencing liquid in the ground by means of a well shaft which is introduced into the ground and is divided into a plurality of shaft areas by at least one partition.
  • Devices of this type with a well shaft divided into several regions by partition walls for generating liquid circuits in the soil surrounding the shaft are already known.
  • the well is filled by a well pipe which is acted upon by a pump which draws in liquid in one well area and feeds it back to the ground in a second well area.
  • the tube has a liquid-permeable wall, which serves as a filter surface for the liquid.
  • the present invention proposes a device of the type mentioned at the outset to enlarge this filter area, which is characterized in that several, provided with a partially liquid-permeable wall and at least partially for generating at least one liquid circuit in the shaft well pipes provided or connected with a liquid delivery device are introduced which, if they are led through several shaft areas, also have a partition wall at the level of the shaft partition walls.
  • the liquid-permeable wall sections of a plurality of thin tubes offer a larger surface overall than the liquid-permeable wall of a single tube with a cross section comparable to that of the individual tubes combined.
  • the effectiveness with regard to the filter effect of a well can therefore be increased even further by introducing several pipes.
  • the cross-section of the well can be chosen smaller to achieve the same effectiveness as when only one well pipe is used, which considerably reduces the drilling costs for producing the well shaft. This enlargement of the filter area is particularly important for filtering viscous liquids such as oil.
  • the effectiveness of the well can be increased further in that all well pipes are led to the lowest shaft area and have a liquid-permeable wall at the level of the individual shaft areas, which forms a filter surface for the liquid.
  • Some well pipes are therefore designed to be longer than would be necessary to generate the at least one liquid circuit.
  • the additional length only serves to form additional filter surfaces for the liquid to be influenced.
  • Individual well pipes can also be provided, which only serve as a filter surface and not for generating a liquid circuit.
  • the well pipes can also be filled with filter material in those shaft areas in which they do not serve to create a liquid circuit, but only form a filter surface for the liquid, which can be matched to the properties of the liquid. This can, for example, promote a phase separation between oil and water.
  • radial spacers can be provided between the individual well pipes.
  • the space between the individual well pipes can then be filled with filter material adapted to the properties of the liquid.
  • Filter gravel in particular as oliophilic material or Teflon balls as oliophobic material are suitable here.
  • Two well pipes 11 and 12 are introduced into the well shaft 10 shown in FIGS. 1 and 4.
  • the shaft 10 is divided into two shaft areas 14 and 15 by a partition 13.
  • the two well pipes 11 and 12 each have a partition 16 and 17.
  • a pipe 19 is connected to a water delivery device 18, here a suction pump, through which the pump 18 sucks liquid from the lower shaft area 15 and the surrounding soil 20 and in the upper shaft area 14 through two lateral Openings 21 and 22 in the pipe 19 and a liquid-permeable wall section 11.1 of the pipe 11, which acts as a filter surface for the liquid, again releases to the soil 20.
  • the well pipe 11 has a liquid-permeable wall 11.1 in the two manhole areas 14 and 15, but also the well pipe 12 is provided with a liquid-permeable wall 12.1 in both manhole areas 14, 15. In this way, liquid also flows through the pipe 12 in the two shaft areas 14 and 15 - in a predominantly horizontal direction.
  • the tube 12 serves here as a pure filter tube and not for generating the liquid circuit indicated by arrows 23. To improve the filter effect, its interior is filled with filter material 27 in both shaft areas 14 and 15.
  • the tube 19 has an upper extension 19.1, which leads out of the well shaft and has a valve 24.
  • the valve 24 When the valve 24 is opened, part of the liquid can be conveyed out of the well via the pipe section 19.1.
  • the lateral openings 21 and 22 can also be provided by valves 25 and 26, as shown in FIG. 4, in order to be able to individually adjust the effective radius of the liquid circuit 23 in the two outflow directions of the openings 21 and 22.
  • the well shaft 30 shown in FIG. 2 is not drilled through with the same diameter in its entire depth.
  • two well pipes 32 and 33 are used in an upper region 31 with a large diameter.
  • the longer of the two pipes 32 is led into a lower shaft area 34 with a smaller diameter.
  • a partition 35 is inserted, in which the end of the tube 33 is anchored.
  • the well pipe 32 also has a partition 36.
  • both well pipes 32 and 33 are each provided with a liquid-permeable wall 32.1 and 33.1.
  • the well pipe 32 also has a liquid-permeable wall 32.1 in the lower shaft area 34, through which liquid is sucked in from the surrounding soil 37 by means of a pump 38 likewise arranged in the well pipe 32 and a suction pipe 39 guided through the partition wall 36.
  • the liquid then passes into a pot-like extension 40 of the tube 39, in which a nozzle body 41 and a further pump 42 are arranged.
  • Due to a negative pressure generated outside the well shaft 30, air is sucked through a pipe 43 under the surface of the nozzle body 41 and drawn in fine bubbles through the liquid located above the nozzle body 41. Contamination is bound to the air bubbles and then sucked out of the shaft via a suction pipe 44.
  • the well pipe 33 also serves to provide additional filter surface for the liquid through its liquid-permeable wall 33.1.
  • the well shaft 50 shown in FIG. 3 is very similar in structure to that described in FIG. 2.
  • a first difference is that the longer of the well pipes 51 has a water-permeable wall 51.1 only in a lower shaft area 52.
  • a pump 54 is arranged in the well pipe 51 in an upper shaft area 53 divided off by a dividing wall 61, the pump 54 being guided via a pipe 55 which passes through a dividing wall 56 in the pipe 51 at the height of the dividing wall 61 between the two shaft areas 52 and 53 is connected to the lower shaft area 52 and sucks in liquid from the surrounding soil 57 there and conveys it by means of the pipe 55 to a treatment device (not shown in detail) outside the well shaft 50.
  • the cleaned liquid then passes by means of a second pump 58 via an inflow pipe 59 into a second well pipe 60 which is inserted into the shaft 50 and which is only guided up to the partition 61 in the shaft 50.
  • the tube 60 has a liquid-permeable wall 60.1, through which the liquid can flow again into the surrounding soil 57 and then again into the lower shaft area 52, thereby forming a liquid circuit indicated by arrows 62.
  • the well pipe 60 is therefore involved in the generation of the liquid circuit 62 and is not merely a filter surface.
  • the space between the well pipes 51 and 60 is in each case with filter gravel 63 filled out. If oil-containing substances are to be removed from the soil 57 by means of the well shaft 50, Teflon balls can also be used instead of the filter gravel 63.
  • the device shown in FIGS. 5 and 6 permits the formation of three liquid circuits 70, 71 and 72 at different depths in the soil 73.
  • a shaft 74 is inserted into the soil 73 and filled with three well pipes 75, 76, 77.
  • the well shaft 74 is divided by partition walls 78 into six shaft areas 74.1 to 74.6. All three well pipes 75 to 77 extend to the lowest shaft area 74.6 and also have partition walls 79 at the height of the partition walls 78 of the shaft, while they each have liquid-permeable walls in the individual shaft areas 74.1 to 74.6.
  • Each of the well pipes 75 to 77 also has an adjustable pump 80 to 82, the pump 80 in the pipe 75 in the partition wall 79 between the shaft areas 74.1 and 74.2, the pump 81 in the well pipe 76 in the partition wall 79 between the shaft areas 74.3 and 74.4 and the pump 82 is arranged in the tube 77 in the partition 79 between the shaft areas 74.5 and 74.6.
  • Each of the pumps 80 to 82 is connected to a tube 83 to 85, which in each case connect the shaft areas 74.2, 74.4 and 74.6 below the pumps 80 to 82 to the outside of the shaft 74.
  • Each of the pipes 83 to 85 also has a lateral outlet 83.1 to 85.1 in the shaft areas 74.1, 74.3 and 74.5 above the pumps 80 to 82, respectively.
  • the pump 80 sucks liquid from the surrounding soil 73 in the shaft area 74.2 and directs a part of this liquid to the outside via the pipe 83, while another part of the liquid again through the side outlet 83.1 of the pipe 83 in the shaft area 74.1 flows out and thereby also flows through the liquid-permeable walls of the other two well pipes 76 and 77 and is filtered by these walls before it again into the surrounding Soil 73 is released and flows again to the shaft area 74.2.
  • the well pipe 75 thus serves only in the shaft areas 74.1 and 74.2 to generate a liquid circuit, while in the areas 74.3 to 74.6 it only serves as a filter surface for the liquid circulated in the circuits 71 and 72.
  • the well pipe 76 only generates liquid circuits in the manhole areas 74.3 and 74.4 and the well pipe 77 only in the manhole areas 74.5 and 74.6, while in the other manhole areas they have a purely filter function and liquid flows through them almost horizontally.
  • the dividing walls 78 between the individual shaft areas 74.1 to 74.6 serve at the same time as radial spacers between the pipes 75 to 77.
  • the spaces between the pipes 75 to 77 are filled with filter gravel 86.
  • the double arrows in the liquid circuit 72 indicate the reversibility of the liquid circuit directions by switching the direction of the pumps 80 to 82.
  • the effective radii of the liquid circuits can be influenced by regulating the output of pumps 80 to 82.
