Definitions

  • the invention relates essentially to a device for creating a horizontal borehole from a starting shaft without the Having to dig up the ground.
  • Each residential and commercial building is underground via a variety of cables laid and disposed of, be it with water, gas or electrical current Etc.
  • a drill pipe is made up of a large number one after the other, usually screwed together, several each Meters long, composed of boring bars, flat from the ground surface drilled diagonally into the ground.
  • the direction of the drilling progress i.e. the am front end of the drill pipe existing drill head, can be relative well controlled so that the bore is initially flat obliquely downwards is performed until the required target depth is reached, and then essentially is drilled horizontally, again under the control of the In the desired direction.
  • the pipeline to be installed is brought into the borehole in that after completing the hole and before pulling back the drill pipe pipe to be pulled in, usually a somewhat flexible steel or plastic pipe, using a special device at the front end of the drill pipe attached and thus the gradual retraction of the drill pipe laying pipe is drawn into the existing borehole.
  • the drill pipe is from one at the rear end on Drilled drill pipe pushed forward and additionally in the Usually the drill pipe is driven in rotation and / or through the exit of Water under high pressure from the drill head that in front of the drill head Material washed out, mostly through a hollow through hole in the Drill pipe.
  • This method is mainly used for laying cables over larger ones Distances, for example 100 m or several hundred meters, used so that the one that cannot be used for a line that must be routed in depth Initial distance on which the hole only reaches its target depth, one represents reasonable effort.
  • the drilling rig used for this which, among other things, has a slant pointing downwards to guide the Must have drill pipe, large and at least two tons heavy, because the weight of the drill partly as a bearing for the force to Presses the drill pipe forward.
  • the main line of a supply line which mostly runs under the street, for example a gas, water or power line, is intended to cross one of them branching house connection line of one of the buildings standing on the street tap.
  • the bore can be controlled relatively precisely be, but it is not possible, on the one hand, with the hole to be drilled drill as close as possible to the main line to be connected, without not at the same time take the risk of damaging this line when drilling.
  • the drilling of the hole in the subsurface would have to be done on a from the main line relatively far laterally offset position.
  • the Setting up the drill would either be on the opposite Take place on the street side and thus block a complete street side, or - there the resulting cross distance is usually not sufficient is likely - in the property opposite in the house to be connected. This would mean that with a z. B. 2 t heavy drill in a garden plot would have to drive in.
  • the resulting Destruction and restoration work already leave for cost reasons discard this method, although in practice this does not include the necessary approval from the property owner would be obtained.
  • the drill pipe is attached to the rear end of the drill pipe
  • the drill pipe in the start shaft is extended, and thereby the drilling forward driven.
  • GB 2 276 895 A1 shows a magazine in which the individual Boring bars are accommodated one above the other in two parallel belts and by means of the straps each individual boring bar at the level of the drilling axis lowered and can be picked up by the drill drive.
  • the second problem to be solved is the immediately adjacent course of the main line to be connected and the main connecting line to be inserted transversely to each other, that is, an attachment of the main connection line directly above or below the main line to connect the two lines Using a suitable T-piece or other adapter in a simple way and To be able to connect with each other without bridging the length.
  • the borehole can immediately only a few millimeters, striving transversely above or below the main line be started, preferably from the main strand opposite side of the starting shaft.
  • a single boring bar is only in its central area, i.e. not in the area their front screw connections with the two neighboring boring bars, flexible.
  • the screw connection itself must under no circumstances be free of play as this will result the directional controllability of the entire drill pipe would be destroyed. Because in the area of the backlash-free screw connection even a pipe Drill pipe is much stiffer than in the middle area of the individual Boring bars, the drill pipe is in the area of its screw connections as hardly to look sideways.
  • a drill pipe which consists of drill rods composed of those that exist at the start and end area Make up approx. 20-25% of the total length of each boring bar, to be regarded as overall not very elastic in the transverse direction.
  • the drill pipe can therefore consist of very many individual, very short Boring bars are assembled. This enables one Starting shaft, the cross section of which is no greater than that in depth given small cross section in the floor surface, a horizontal Achieve drilling progress with a drill string, the individual Boring bars in the direction of the drilling axis to the rear end of the existing drill pipe can be applied. As a result, the individual Boring bars must be significantly shorter than the length measured in the horizontal the cross section of the starting shaft.
  • Rotating the drill string around the soil material in front of the drill head scraping or loosening up makes sense only in exceptional cases.
  • turning the drill pipe by less than 360 ° must be possible because via an asymmetrical bevel at the top of the drill pipe and their angular position with respect to the drilling axis, the direction of the drilling feed is controlled.
  • the boring bars to be added are each on the rear end of the drill pipe screwed on. It is preferably done beforehand with the help of the changer motor and the threaded connector attached to it Shot from the higher boring bar magazine.
  • the drill drive itself which - as previously described - primarily or exclusively pressing forward in the direction of the drilling axis is in the starting shaft Can be pushed back and forth parallel to the drilling axis, at least around the length of a single boring bar.
  • the drill drive preferably moves between an advanced position immediately at the beginning of the Drill hole in the starting shaft, and a retracted position in the Close to those arranged on the opposite wall Boring bar changing device is arranged back and forth.
  • Both the boring bar changer and the boring drive are preferred arranged within a derrick, which consists of a latticework There is metal pipes and preferably on its peripheral walls with plates is covered against falling earth into the starting shaft.
  • This The drilling rig is whole, for example by means of a hand winch, from above lowered into the starting shaft.
