Definitions

  • the invention relates to a method for producing bores and / or for introducing suspension, in particular cement suspension, under pressure into a borehole, the borehole being able to be produced in a conventional manner by drilling and, if appropriate, suspension subsequently being introduced, or the borehole using the soil concrete method or a similar method with simultaneous introduction of the suspension during the drilling process.
  • the object of the invention is to provide a method by means of which bores and / or injections are properly produced even under unfavorable conditions and the quality of soil areas or soil columns produced by injections or of in-situ concrete piles regardless of the chosen position, i.e. in particular also in the direction of the boreholes and those below the groundwater table, and the risk of missing parts or complete failure is significantly reduced.
  • the solution to this lies in a method of the type mentioned, which is characterized in that the opening of the borehole is sealed off from a drill or injection rod and the returning material is discharged in a controlled manner in a pressure or quantity-controlled manner from a return line connected to the borehole.
  • material stands for drilling fluid, suspension for soil consolidation and sealing, as well as soil material in all mixing ratios.
  • quantity-controlled supply of drilling fluid or suspensions controlled drainage can also consist of a quantitative check.
  • the suspension is preferably kept under a controllable pressure during drilling and / or injection in the borehole, which pressure can be set to a desired value.
  • gas or water bags which form at the highest point of the borehole are filled up by suspension under pressure during or after the hardening of the suspension, the water possibly being drawn off beforehand from water bags.
  • the risk of the formation of such gas or water bags is present in particular in the case of bores drilled at an incline upwards, but on the other hand also cannot be ruled out in bores which are inclined downwards and have a slight incline or poorly permeable soil / suspension mixture.
  • a suitable device for introducing suspension into a borehole under pressure according to the method described above is characterized by a sealable insert into the borehole or its casing Connection piece, a pinch or membrane valve connectable to the connection piece with a rigid piece with external pressure supply and an internal pressurizable sealing hose made of elastic material, an insertion funnel on the pinch or membrane valve, an insertion piece with a guide that can be inserted into the pinch or membrane valve via the insertion funnel - And sealing arrangement for a drill or injection rod, an axially movable drilling mast with a rod guide for the drill rod and an adjustable pressure maintenance device.
  • Characteristic of this device is the permanent connection of the connecting piece and the pinch and diaphragm valve with the borehole on the one hand and the connection of an insertion piece which can be inserted therein sealingly via an insertion funnel with a drilling and injection rod on the other hand. This makes it possible to prepare a plurality of boreholes for carrying out the method and then to carry out the drilling and injection method with a single drilling and injecting arrangement, or to prepare the injection method for boreholes which have already been produced.
  • the sealing connection of the connecting piece with the opening of the borehole is preferably made in that a plate closing the bottom region at the borehole is provided with a borehole, whether made of cement or concrete, or steel, with a borehole into which the Connection piece is used and, depending on the material, is concreted in, glued in or welded in.
  • the pinch or diaphragm valve connected to the connecting piece is preferably designed to be separable from it, so that it can be dismantled immediately after the process has ended while the connecting piece is opposed also remains at the borehole.
  • Pinch or diaphragm valves of the type mentioned are known components as such, in which the elastic hose can be pressurized with high pressure up to several bar after insertion of the connecting piece connected to the drilling and injecting arrangement, so that a secure seal takes place which occurs during the Injecting and curing can maintain the required pressure in the borehole.
  • a closable slide is provided in the connecting piece, which is to be closed before the pinch and diaphragm valve is dismantled after the drilling and injection rod has been pulled out.
  • the open end of the nozzle after dismantling can be provided in a further embodiment for the attachment of a closure cap.
  • an insertion opening can be provided with suitable sealing means for inserting a discharge and injection tube, via which gas or water bags at the rear end, i.e. are to be deducted in particular at the highest point of a column and to be filled up specifically with suspension which would not be possible by direct insertion from the borehole.
  • the tube can first be closed in a known manner with an end plug which is blown free by pressure.
  • the pressure holding valve referred to above can be arranged in a favorable embodiment on the insertion nozzle connected to the drilling and injection device. This has the advantage that the pressure-maintaining unit only has to be provided in a simple version and that floor columns created one after the other are created under the same pressure conditions. Regardless of that, it is also possible to provide the pressure control valve on the connection piece firmly connected to the borehole. Parts, which are preferably carried out on this connection piece in each case, are a connection with a repressing valve and a connection with a pressure measuring point. The pressure at this pressure measuring point can be used for a safety circuit of the suspension feed pump of the drilling and injection arrangement.
  • the pressure in the borehole can be kept constant until it hardens by means of appropriate connections.
  • the post-compression connections can be connected via a ring line and in this way guarantee consistent quality of all floor columns.
  • a return line connected to a compressed air boiler can also be provided as the pressure maintaining arrangement.
  • This compressed air boiler is then in turn connected to a pressure regulating device and possibly to a pressure generator.
  • Suitable guiding and sealing means for the drilling and injecting rods are to be provided on the insertion stub, since a closed system from the connection stub over the pinch and diaphragm valve to the insertion stub must be shown during the drilling and injecting process.
  • the device according to the invention can also be used for a customary drilling and injection method with free discharge of the excess or return quantity by opening the mechanical or pneumatically adjustable pressure holding valve.
  • FIG. 1 shows a sealing plate 7 which seals the bottom 28 and into which a connecting piece 8 is inserted in a sealing manner, for example is cemented in place.
  • a nozzle attachment 29 with a pressure measurement connection 12 with a valve is attached via a quick-release fastener 10, which leads to a pressure measurement point.
  • a pinch or membrane valve 13 with an internal sealing tube 14 and a compressed air supply 15 is flanged to the connecting piece 29.
  • the hose is in a relaxed position.
  • an insertion funnel 16 which serves to facilitate the insertion of an insertion socket 17, which is provided with an edge protector 18 in order to avoid damage to the closure tube.
  • the insertion nozzle 17 is by means of a fastening bracket 25 is attached to the drilling mast 6, which holds a drilling rod 3 in a rod guide 4, at the front end of which a nozzle head 2 and in front of it a drilling cone 1 with flushing outlet can be seen.
  • a so-called breaking device 5 with clamping jaws which is used to connect individual boom sections.
  • the drill pipe 3 is inserted sealingly into the insertion funnel, which is closed at the bottom, via a sealing arrangement 20.
  • Connection 21 is provided as a sealing liquid inlet.
  • a further refill or refill connection 19 with a valve is provided on the inlet connection 17, which can be regarded as an alternative to the first refill and refill connection 9 on the connection socket 8.
  • a return nozzle 24 is provided on the filler neck, which can be closed via a poppet valve 22, which comprises a controllable pressure control unit 23.
  • FIG. 2a the connecting piece 8 is shown in the same design as in FIG. 1, the attachments being dismantled starting with the connecting piece attachment 29 and the connecting piece 8 being closed off by means of the quick-release fastener 10 with a cover plate 11.
  • connection piece 8 is shown in the same design as in Figure 1, followed by a slide unit 26 is attached to it by means of the quick-release fastener 10, and behind the slide by means of a further quick-release fastener 30, in turn, a closure cover 11 can be seen, which has an insertion opening 27 for an exhaust pipe.
  • FIGS. 3 and 4 essentially the same parts as in FIG. 1 can be seen, but the insertion nozzle has not yet been inserted into the membrane valve, but this is shown in the closed position by pressure application via the pressure connection 15. Otherwise, the same individual parts are designated with the same numbers as in the previous figures.
