    • E04B1/6816—Porous tubular seals for injecting sealing material

Definitions

  • the invention relates to an injection hose for joints to be sealed in concrete structures according to the preamble of claim 1.
  • Injection hoses of the type mentioned are intended to allow an injection liquid to exit under pressure, on the other hand to prevent concrete particles or concrete mass from entering the injection hose from the outside.
  • the known injection hoses (EP-PS 199 108, DE-GM 84 25 518) work with closure bodies of radial openings which can be compressed under the pressure of the injection liquid and are complex and correspondingly expensive both in terms of their manufacture and the materials used.
  • An injection hose with the features mentioned at the beginning is also known, the liquid-tight outer shell of which is intended to break open in places under the pressure of the injection liquid.
  • this inexpensive injection hose does not guarantee the desired seal, because the outer shell often does not tear open at all or all of the desired points and, moreover, material can penetrate into the injection hose from the outside at the tear points.
  • a valve device on a pipe of a drill pipe is known, with which chemical solutions are to be introduced into the soil under pressure.
  • the tube has large radial areas Openings and is surrounded by an elastic shell with a variety of slots.
  • these slots partially overlap with the radial openings of the pipe, as a result of which liquid can penetrate into the pipe of the drill pipe from the outside.
  • the only remedy is to attach valve flaps in front of the slots.
  • the arrangement is not suitable for injecting concrete into the joints to be sealed in a building, since only joints on straight concrete walls could be sealed with a rigid pipe.
  • the uneven arrangement of the openings in the pipe and in the casing means that the concrete cannot be evenly distributed in the joint.
  • the invention has for its object to design an injection hose of the type mentioned so that it remains inexpensive to manufacture and ensures an escape of injection liquid in the entire injection area.
  • the radial openings of the tightly fitting, circumferential sheath are each separated from the radial openings of the inner supply hose by contact areas. Leaves under the pressure of the injection liquid the circumferential envelope at the radial openings of the supply hose stand out with elastic deformation, so that the abovementioned contact areas disappear and a passage of the injection liquid escaping from the supply hose through its radial openings under pressure to the radial openings of the outer casing.
  • the passage cross-section for injection liquid formed by radial openings of the supply hose per peripheral surface unit of the injection hose can be kept larger than the passage cross-section formed by the openings of the casing, which can be achieved by different opening diameters or by different opening numbers in the supply hose and in the outer casing.
  • An injection hose designed according to the invention can be produced at low cost.
  • the fitting of the adjacent outer sheath onto the supply hose while avoiding overlap of the radial openings of the two hose structures can be accomplished easily and without great mechanical effort.
  • a smaller passage area of the outer casing compared to the passage area of the supply hose favors a uniform injection liquid outlet over the entire hose circumference in the injection area.
  • the use of compressible porous closure bodies or coating surfaces is not necessary.
  • the injection hose 10 consists of an inner supply hose 11, which is made of a bendable or elastically bendable, liquid-impermeable material, in particular plastic material.
  • the supply hose 11 is surrounded by a thin-walled envelope hose 12, which lies tightly against the outside of the supply hose 11 and is made of an elastically stretchable material.
  • the supply hose 11 is provided with radial through openings 13 arranged in rows and at a mutual distance from one another.
  • the outer jacket tube 12 is also provided with rows and at a distance from each other through openings 14 which are offset from the openings 13 of the supply hose.
  • the number of through openings 13, 14 and their distribution over the circumference of the injection hose 10 can be as desired. In the illustrated embodiment, there is a uniform circumferential distribution of the through openings shown.
  • the through openings 13 of the supply hose 11 have a larger diameter than the through openings 14 of the enveloping hose 12.
  • injection liquid for example concrete milk
  • this injection liquid exerts pressure in the area of the through openings 13 of the supply hose 11 on the tightly fitting casing tube 12, under which the casing hose 12 is located at this point due to its can bulge elastic property, as can be seen from Fig. 3.
  • connecting spaces 16 are formed between the through openings 13 of the supply hose 11 and the through openings 14 of the enveloping tube 12. Through these connecting spaces 16, the injection liquid reaches the through openings 14 of the outer enveloping tube 12 and exits there, as shown in FIG. 3 by arrows 17 is indicated.
  • the outer enveloping hose 12 lies tight against the supply hose 11 again due to its inherent elasticity, so that a backflow of liquid from the outside to the through openings 13 of the liquid-impermeable supply hose 11 is prevented.
