Definitions

  • the invention relates to a method for pressing injection compounds into cracks or capillaries of components.
  • DE-OS 31 17 286 shows a so-called packer with a tubular filler neck, which is sealed in a borehole made in the component.
  • the filler neck is fixed by a rubber sleeve surrounding it, which is clamped radially in the borehole with axial shortening.
  • a device that is simpler in comparison is known from DE-OS 32 03 871.
  • the packer that can be removed from this essentially has a conical outer contour with which wedging in the borehole is achieved for the purpose of sealing and fixing the packer.
  • the holding values are usually not sufficient to be able to withstand the back pressure that occurs when the injection compounds are pressed in, so that the packer is released and the sealing effect is lost.
  • cement mortar After the cement mortar has hardened - which may take a long time - cement mortar is again introduced into the lower part of the borehole for anchoring purposes.
  • a tie rod which is inserted into a borehole crossing the various layers of the earth, forms the element holding the layers together.
  • cement mortar is introduced into the gap between the tie rod and the inner wall of the borehole, which creates a connection between the individual layers of soil and the tie rod. Since only the borehole, ie the gap between the borehole wall and the tie rod, has to be filled with cement mortar, the pressures required to insert it are not as high as is necessary for cracks to be repaired at the beginning.
  • the mortar introduced for fixing in the outer region of the borehole is therefore not subject to high demands, particularly from the point of view of the pressure conditions.
  • the invention is based on the object of specifying a method for injecting injection compounds, preferably into cracks in components, which is characterized by simplicity in terms of handling and the means used and creates a reliable seal when the injection compound is pressed in.
  • the object is achieved in that a borehole crossing the cracks is made in the component, a tubular filler neck with a smaller diameter than the borehole is inserted into the borehole, the filler neck is sealed by introducing hardening sealing compound into the gap between the filler neck and the borehole wall and after the has hardened Sealing compound the injection compound is pressed into the component through the filler neck.
  • the filler neck is surrounded by the sealing compound at least in the outer region of the borehole, so that the neck is fixed and sealed after it has hardened.
  • a pressing device customary for such compounds is used for the filling of the sealing compound into the annular gap between the borehole wall and the filler neck.
  • These squeezing devices have discharge ports which enable the sealing compound to be fed into the annular gap with sufficient accuracy.
  • the distribution of the sealing compound in the annular gap is generally also sufficient if the dispensing nozzle is only attached to one point of the annular gap. In order to nevertheless facilitate the distribution of the sealing compound, the dispensing nozzle can be attached several times along the circumference of the annular gap.
  • sealing compound has to be used for the fixing and sealing of a single filler neck can be left to the experience of the operator. As a rule, it is sufficient if only the outer area of the filler neck is surrounded by sealing compound. If sealing compound flows down to the deepest hole, this has no influence on the subsequent injection with injection compound, since the pressures used with these injection compounds are so high that disturbing residues of sealing compound would be removed or avoided.
  • both physically and chemically solidifiable sealing compounds can be considered for the method according to the invention.
  • the physically solidifiable sealants - which includes, for example, a hot melt adhesive - seen from the point of view of the equipment involved, if a relatively large amount of effort is required, chemically solidifiable masses, for example in the form of two-component mortar masses, are considerably better from the point of view of the equipment . For this reason, such two-component mortar compositions are particularly preferred for the process in question.
  • These two-component mortar compositions can be preparations made from epoxy, polyisocyanate or polymerizable unsaturated acrylic or, in particular, polyester compounds. All of these mortar compositions proposed as sealing compounds are characterized by a sufficiently high viscosity, which corresponds to approximately ten times the injection compositions used, and have a curing time of only a few minutes.
  • the device for carrying out the method according to the invention is characterized in that the filler neck is designed as a tube with a spray nipple.
  • a filler neck in this regard is extremely economical in terms of both manufacturing and material costs.
  • the pipe is cheap bulk goods and the spray nipple on the other hand is a commercially available bulk product, such a spray nipple being provided with a check valve known per se.
  • the material for the tube can be selected in various ways; both metals and plastics are suitable.
  • the only processing effort that is put on the pipe is the length adjustment and the adjustment of the connection to the spray nipple, preferably in the form of an internal thread.
  • the length of the filler neck including the spray nipple is preferably greater than the depth of the borehole. This ensures that at least the spray nipple, but preferably also a part of the pipe, protrudes from the borehole over the surface of the component to be filled.
  • the filling of the annular gap is thereby made considerably easier in that the discharge nozzle can be brought up to the part of the filler neck which projects beyond the component. This ensures that the inlet opening of the spray nipple is not covered by the sealing compound.
  • the part of the filler neck protruding from the component can remain. However, if this has a disruptive effect, there is the possibility of separating or removing the entire filler neck by pulling it out.
  • the protruding part of the filler neck can be cut off by cutters or by breaking off, in order to facilitate the latter case provision can be made in the form of notches or the like on the filler neck.
  • a filler neck 4 consisting of a pipe 5 and a spray nipple 7 screwed to it via a thread 6, is inserted into the boreholes 3.
  • the tube 5 extends up to a circumferential notch 5a, which serves as a visual marking and creates a predetermined breaking point, into the borehole 3.
  • the spray nipple 7 forms, together with a ball 8 and a compression spring 9, a check valve.
  • sealing compound 12 is introduced into the gap existing between the tube 5 and the borehole wall by means of a dispensing device 11. This hardens within a few minutes and thus fixes the filler neck 4 in the component 1.
  • injection mass 14 is pressed into the borehole 3 through a central bore 5b of the tube 5.
  • the injection compound 14 enters the cracks 2 and, through the adhesive effect, leads to the component 1 solidifying.
  • the area of the filler neck 4 protruding from the component 1 can be separated from the remaining part located in the borehole 3 at the predetermined breaking point formed by the notch 5a.
