Definitions

  • the invention relates to a method for designing well areas to promote well effectiveness.
  • the invention has for its object to design well bores so that their operating time is increased significantly.
  • the method according to the invention ensures that a high flow velocity of the liquid flowing into the well pipe results in the suction area of a well.
  • the braking caused by a conventional gravel lining of different densities does not apply. This significantly reduces silting of the well pipe environment compared to conventional wells.
  • a more or less large-scale horizontal desludging can also be achieved in different soil layers that are spaced apart in the vertical direction.
  • the application of this method is particularly suitable for well systems for cleaning contaminated soil areas and groundwater on the spot, where a liquid flow is forced in the soil between well pipe wall areas that are vertically spaced apart.
  • large, flushed-out floor areas can advantageously and subsequently be at least partially filled up again with pourable, flushable fillers, the size and material properties of which may depend on the purpose of the well in question.
  • bodies with a large surface area made of ceramic material, for example, which are suitable for the adsorption of gases and dissolved substances and / or for the nesting of microorganisms can be chosen as the filling body.
  • commercially available filter bodies can also be flushed in as fillers.
  • the important process step of rinsing out areas of the liquid-bearing soil layers can be favored by making several additional bores around the first borehole at a distance that still allows rinsing out, and later using the central first borehole as a well bore.
  • a rinsing-out distance is to be understood as the distance to be selected in which, by pressing into the outer borehole in the area of the central borehole serving as a reflux borehole, the liquid flow is so strong that the pressure between the boreholes is due to the pressure difference created Connection channels are created and ultimately a flushing out of soil material is achieved around the central borehole.
  • a drill pipe used to inject liquid or to discharge the pressure fluid and the dissolved solids can be continuously moved forward.
  • a central borehole and, at a short distance from it, two additional boreholes 11 and 12 are driven into the bottom 13 on both sides for carrying out the method mentioned at the beginning.
  • drill pipes 14, 15 and 16 can be used, which are screwed or driven into the ground and with which the method can be carried out after removing the drill core.
  • Drill pipes can later also function as well pipes.
  • the drill core provides information about the nature of the various perforated soil layers, which are designated by letters AF in FIG. 2.
  • the boreholes 10 to 12 formed can, however, also be introduced after removing the drill cores from the boreholes 14-16 measuring probes, not shown, with which the groundwater permeability of the individual soil layers AF can be determined, for example, using groundwater measurement samples.
  • the well system chosen as an example is of interest to two layers of soil that are at a vertical distance from one another and are relatively well permeable to water. These are the soil layers C and F, which are mainly sediment layers consisting of sand and gravel.
  • the first step is to gradually drill hole 10. As soon as the removed core shows that a first well-drained soil layer, here layer C, has been reached, the other two holes 11 and 12 are also drilled to the same height . If it turns out that the bottom layer C has also been hit by these holes and that it is not just a small sand and gravel lens, the rinsing of the bottom layer C in the area of the holes drilled begins. Water is pressed under high pressure into the middle drill pipe 14, as indicated in FIG. 2 by the downward arrow 17. At the same time, groundwater is extracted from the two other drill pipes 15 and 16 together with the sand and gravel material loosened by the pressurized water 17 pressed into the central bore 10, as indicated by the two upward arrows 18 and 19.
  • this step of the method it is possible, in particular at the beginning, to switch between the three drill pipes 14 to 16 with the entry of pressurized water, thereby loosening the sediment material is facilitated.
  • the drill pipe introducing pressurized water can be moved forward over the height of the bottom layer C during the pressurized water entry.
  • this rinsing creates a more or less homogeneous cavity 20, the limitation of which is indicated in FIG. 1 and FIG. 2 by a dash-dotted or solid line 21.
  • the central bore 10 is driven further with the central drill pipe 14 until the second, well water-bearing bottom layer F is reached.
  • the rinsing process described above is repeated there and a second, more or less homogeneous cavity 22 with the boundary line 23 is created.
  • the two cavities 20 and 22 formed are then filled with granular ceramic material with a large pore surface, which is flushed into the cavities with water.
  • the ceramic grains can be populated with soil-cleaning microorganisms.
  • the central borehole 10 is drilled out into the region of the cavity 20 to a much larger diameter, which allows the insertion of a cylindrical soil remediation device 25.
  • a production pipe 26 is inserted, which ends at the bottom in the cavity 22 filled with the ceramic grains 24.
  • the upper end of the conveyor pipe 26 is expanded to an insertion funnel 27 arranged just above the upper cavity 20.
  • the remediation device 25 consists of a tubular casing 28 inserted into the enlarged bore part, which is closed with a cover 29 on its upper end projecting above the earth's surface 60.
  • the tubular jacket 28 is open at its lower end located in the cavity 20.
  • a cleaning insert 30 can be introduced into the tubular jacket 28, the construction of which is not of interest in the context of the present invention and the mode of operation of which is described in German patent application P 42 03 382.9.
  • This cleaning insert 30 ends both below and above with a concentric pipe section 55 and 54.
  • the lower pipe section 55 can be pushed tightly into the conveying pipe 26 by the conically widened upper end 27, while the upper pipe section 54 follows through a central opening of the cover 29 protrudes outside.
  • the cover 29 has an additional opening for the connection of a fan 40 for generating a negative pressure in the upper part of the casing tube 28.
  • An electrically operated feed pump 50 is arranged in the cleaning insert, by means of which groundwater is conveyed from the bottom layer F through the filled tube 22 through the filled cavity 22 into the cleaning area of the cleaning insert 30. Subsequently, the groundwater flows out through a filter area filled below the inner end of the tubular body 28, which is filled with filter bodies 35. Through the filter area, which is not absolutely necessary, the groundwater can flow further into the cavity 20 in the bottom layer C, which is at least partially filled with ceramic grains 24, and a liquid cycle is forced between the bottom layers C and F over the intermediate bottom layers D and E.
  • the two adjacent bores 11 and 12 can remain piped according to FIG. 3 and can be used for various purposes, here for example for feeding treatment substances, treatment gases or microbes into the cavities 20 and 22.
  • the bores can also serve as ventilation bores.
  • two additional bores 51 and 52 are indicated with dash-dotted lines, with the aid of which larger cavities which are more concentric with the central bore 10 can be flushed out during the implementation of the method, the delimitation of which is indicated by a dash-dotted line 53.
  • a dash-dotted line 53 In the case of well systems for the extraction of drinking water, as a rule only a single well water-bearing soil layer is drilled, in which the rinsing and - depending on the nature of the soil - a subsequent support and filter filling is then carried out. Subsequent drilling of the hole selected for water production can then generally be omitted, which considerably reduces the cost of drilling the well.
  • the diameter of the well pipe used depends on the drill pipe diameter.
