Definitions

  • the invention relates to a method for building a well, one vertical shaft and at least one extending in the horizontal direction, in the shaft has a terminating socket strand.
  • the bottom of the shaft is concreted. Be from the shaft then through openings in the shaft wall in a star shape horizontal bores are driven with drill pipes. In these drill pipes then insert the filter pipes, then the drill pipes are removed. With the Preussag process the filter tubes are additionally covered with a gravel coat surround.
  • a filter strand pull-in unit is consisting of a filter string and a outer cladding tube is retracted. After moving in the outer cladding tube of the filter strand pull-in unit is removed. The filter strand pull-in unit is over full pipes to a removal device standing on the surface connected in which the for the extraction of groundwater, of the backwater or soil air pumps, suction devices, Vacuum generator or the like are housed.
  • the horizontal bores can have a curved course and the individual filter strands can have a length of have up to 500 m.
  • the disadvantage of this is known To look at procedures, the water production from a maximum suction head of the pumps exceeding the depth Installation of a pump in each individual filter train requires the comparatively small diameter of the filter tubes of the filter strand significantly increases the delivery rate restricted.
  • the invention has for its object a method for To indicate the construction of a well of the type mentioned at the beginning, that can be carried out easily and quickly is characterized by low labor and material costs.
  • the method is also intended to build such a well without performing manual work inside of a shaft structure.
  • the method has the advantage that all Work on the construction of a well carried out from above can be.
  • the vertical Dismantled shaft in the manner of a vertical well, where the stop of the horizontal frame strands on the vertical wells by deliberately drilling a provided for this purpose, filled with suitable filter material Capacity of the vertical shaft is done. This procedure allows the work, material and time required to build a horizontal well Reduce socket strings considerably.
  • Another advantage of the method according to the invention is to be seen in that for the production of the strand bores course-controlled drilling methods can be used which allow a curved hole pattern.
  • the length of the socket strands can also be many times be larger than with conventional horizontal filter wells according to the procedures of Albertmann or Preussag.
  • the horizontal socket strands can be different Procedures are applied. It is also suitable for this the method specified in DE 43 13 221 C2.
  • the method according to the invention is suitable for all sizes from fountain.
  • the dimensioning of the lines and the Filter tubes are independent of the construction. Everyone can usual pipe cross sections can be combined.
  • the process allows both the construction of wells on a small scale Plots as well as the extension to large-scale Areas, e.g. whole neighborhoods too.
  • the shaft can also be outside the scope of the horizontal frame strings. This is in confined spaces Conditions, for example in built-up areas of importance.
  • the vertical shaft drilling can be carried out using the flush drilling method or in the dry drilling process.
  • This Process works with an auxiliary piping that simultaneously with the filling of the socket section or is then removed from the socket section to the Strand bores the passage through the socket section to enable.
  • the dry drilling method is also suitable for further training of the method according to the invention, in which the vertical Well drilling from a main drilling and one or several secondary holes intersected with the main hole is formed. It is provided that the first Sub-drilled and in the socket area with filter gravel or single-grain concrete, otherwise filled with filler material and then the main bore is sunk and with a vertical filter tube string and one to the socket area the filter zone adjacent to the secondary bore becomes.
  • This design allows for little effort a larger horizontal extension of the frame area, which penetrate the horizontal strand bores.
  • the horizontal strand bores can be made that they only penetrate the secondary holes and on the Run past the main bore. This can expand the Main bore irrespective of the sinking of the strand bores be performed.
  • In the secondary holes can also Level pipes or regeneration filters can be installed.
  • Wells executed by the method according to the invention are suitable for numerous applications, especially for Water extraction, for lowering groundwater, for water drainage in civil engineering, for grasping and draining contaminated Water or soil air or for large areas Infiltrate water or air.
  • soil conditions with poor water permeability also exists the possibility to apply vacuum to the well, to improve the drainage of water from the aquifer.
  • the construction of the well shown in Figures 1 and 2 first begins with a vertical well bore 1 through the layers of a overburden 2 into the aquifer Layers of an aquifer 3 is sunk.
  • the Drilling takes place using the dry drilling method an auxiliary pipeline consisting of drill pipes.
  • the diameter of the drill pipes can be up to 1600 mm depending on requirements 2500 mm.
  • the depth of the shaft bore 1 is aimed according to the one intended for the lowest socket strand Depth and should be under the bottom of the bottom socket string lie. Has the shaft hole 1 the intended Reached depth, so it becomes one for the provided later installation of vertical filter tubes 4 Height filled with filter gravel or single-grain concrete.
  • the height of the filled, referred to as socket section 5 Section of the shaft bore 1 must be so large be dimensioned, dag the intended number of horizontal frame strands 6 at a sufficient vertical distance can be introduced into this.
  • the next step will be to build the horizontal socket strands 6 with the help of a course-controlled flush drilling method two horizontal strand bores 7 drilled.
  • Each strand bore 7 has an inlet opening for several days 8 and an outlet opening 9 and penetrates with its deepest, horizontally running Area of the socket section 5 of the shaft bore 1, with their sections on either side of the well bore 1 an at least slight slope towards the Can have shaft hole 1.
  • Within the socket section 5 run in different directions intersecting strand bores 7 in different Heights and such a distance from each other, do not interfere with each other when drilling.
  • In the strand bores 7 then become filter tube strands moved in and anchored for days.
  • the filter tubing strings exist within the scope of the Aquifer from filter tubes, which can also be used if required can be provided with a coat of filter gravel.
  • the area of the overburden 2 has the filter tube strands Full pipes on. When pulling into the strand bore 7 can the filter tube strings are protected by a cladding tube be removed after being drawn in. The ends of the Filter tube strands are open to the surface with removable closures closed and installed so that it can be used later Inspection or regeneration measures accessible stay.
  • the shaft bore 1 is expanded further the filled socket section 5 is a strand Filter tubes 4 and top tubes 10 placed.
  • the remaining one Annulus 11 is in the area of the filter tubes 4th with a bed of filter gravel, over it with a suitable one Backfill material backfilled.
