Definitions

  • the invention relates to a method for sealing joints on structures with the aid of an injection hose made of a substantially liquid-impermeable base body which surrounds a passage channel and which has outlet openings for injection liquid distributed over its length into the joint to be sealed.
  • injection hoses of the type mentioned in DE-OS 35 12 470, DE-OS 33 20 875 or DE-GM 84 25 518 have been developed, which are installed in the construction joints and through which an injection liquid is pressed into the joint area to fill them waterproof.
  • the grouting process usually takes place when the hardening of the concrete and thus the relaxation behavior typical of the building material has been completed.
  • the injection liquid is pressed into the passage channel of an essentially water-impermeable base body, from which it can exit through outlet openings into the vicinity of the hose.
  • the outlet openings are covered, for example, by strips of compressible material placed in depressions arranged on the outside of the base body.
  • the Injection hose is held together by a hose made of liquid-permeable material surrounding the base body and the strips.
  • the pressure compresses the strips and the fingers between the depressions and the strips are expanded so that the injection liquid can escape from the injection hose.
  • the injection liquid is then allowed to harden, as a result of which the joint is usually sealed by the injection liquid emerging from the injection hose, but the injection liquid in the hose interior is also hardened. It is not possible to check the seal.
  • the passage channel is free again and the injection hose is available for pressing again.
  • joint areas that are not completely filled can be filled in immediately after the first pressing during the first pressing.
  • the re-grouting can also be carried out after a more or less long time if the joint should have proven to be leaking or new cavities or cracks should be filled with injection liquid and sealed over the course of time. Even those when grouting Injection liquid remaining in the injection hose can be withdrawn from the injection hose under the same conditions as when the first injection, so that it is available for reuse.
  • injection liquid is removed as completely as possible from the injection hose so that subsequent injection or a leak test is not impeded by hardened residues of injection liquid that remain in the injection hose and block it. According to the invention, this can advantageously be done by means of vacuum suction.
  • the injection hose can also be flushed with water and / or blown with compressed air after the injection liquid has been sucked off.
  • the post-grouting according to the invention for complete or renewed sealing of the construction joints immediately after the hardening of the injection liquid in the joint area or a longer time thereafter is advantageously carried out at a higher pressure than the first pressing. It has been found that such uncompressed areas can also be used to fill previously unpressed areas, even small pores or structural defects in the vicinity of the injection hose.
  • the leak test using water under pressure is preferably carried out according to the invention in such a way that the pressure is maintained over a longer period of time, for example a few days. This enables a reliable statement to be made about the tightness of the joint.
  • water-miscible, reactive curing synthetic resins, vinyl ester-based resins, polyurethane resins or ultrafine cement with liquid additives are used as the injection liquid.
  • Epoxy resins are also suitable.
  • Injection materials that swell when exposed to water are desired, which additionally supports the sealing of joints and cracks. This swelling can be almost reversible due to the drying of the injection material.
  • Injection liquids based on water glass with hardener systems suitable for the application are also conceivable.
  • Both vinyl ester-based resins and ultrafine cement are water-soluble in the fresh state, so that empty injection hoses and devices can be easily cleaned by rinsing with water and are then available again for any subsequent grouting or leak tests.
  • the polyurethane resins which can also be used as injection liquids, are not water-soluble, and are therefore preferably repressed only within the dropping time according to the invention. With this injection agent, cleaning of the hose system is less possible.
  • the single figure shows the cross section of an injection hose, which can preferably be used for the method according to the invention.
  • the injection hose 1 consists of a base body 2, which has an essentially hollow cylindrical wall and thereby forms a central cylindrical passage 3 extending through the length of the hose.
  • injection liquid is introduced in order to distribute this over the length of the joint to be sealed, to which the injection hose 1 is assigned.
  • Four indentations 4, 5, 6 and 7 are provided at equal angular intervals over the circumference of the base body 2 and extend over the entire length of the base body 2.
  • Radial openings 8, 9, 10 and 11 are provided in the hose wall for the flow connection of the passage channel 3 with the depressions 4, 5, 6, 7, which openings are provided on the one hand in the passage channel 3 and on the other hand in the depressions 4, 5, 6 and 7 open.
  • strips 12, 13, 14 and 15 of reversibly compressible material are arranged, the shape of which is adapted to the shape of the recesses 4, 5, 6 and 7.
  • the base body 2 and the arranged in the recesses 4, 5, 6 and 7, with the outer periphery of the base body 2 essentially closing strips 12, 13, 14 and 15, are of a tube 16 made of a thin liquid-permeable or under the influence of Injection liquid surrounding material.
  • the strips 12, 13, 14 and 15 are held securely in their depressions 4, 5, 6 and 7, even when the pressure of the injection liquid is present from the inside.
  • the penetration of concrete components from the outside through the openings 8, 9, 10 and 11 into the passage channel 3 is reliably avoided, since when the pressure from the outside increases, the strips 12, 13, 14 and 15 have the openings 8, 9, 10 arranged in longitudinal rows and just close 11 even better.
  • injection liquid is pressed into the outlet channel 3 of the injection hose 1.
  • the injection liquid emerges through the outlet openings 8, 9, 10, 11 into the environment in order to seal the joint.
  • the not yet hardened injection liquid remaining in the injection hose 1 is sucked out of the passage 3.
  • the strips 12, 13, 14 and 15 lying in the depressions 4, 5, 6 and 7 are drawn to the base body 2 by the resulting negative pressure and thereby close the openings 8, 9, 10 and 11, so that the injection hose 1 is sealed with respect to the joint and the injection liquid escaping during compression is not sucked back into the injection hose 1.
  • the injection material is sucked out of the injection hose 1, for example by means of a vacuum system.
  • the injection hose 1 is rinsed with rinsing water until it is clear and no longer has any traces of injection material.
  • the injection hose 1 is then blown through with compressed air in order to also remove the rinsing water from the injection hose 1 as completely as possible. This makes the hose suitable for subsequent grouting.
  • injection fluid can be injected.
  • joint areas can be filled, which the grouting material e.g. could not reach due to leakage during the first pressing.
  • the injection hose 1 is cleaned again as described above.
  • the injection liquid in the joints has hardened, it can be re-grouted, but preferably at increased pressure. As a result, previously unpressed areas - even small pores or structural disorders in the vicinity of the injection hose 1 - can be filled.
  • a leak test of the joints can be carried out with water.
  • water is preferably pressed into the emptied injection hose 1 at a pressure corresponding to the construction site. The pressure is maintained over a long period of time, for example several days. Any leaks in the construction joints can be detected by any water leaks. If such leaks occur, the sealing can be carried out by re-grouting with grouting material.
  • Water-miscible, reactive-curing synthetic resins, vinyl ester-based resins, ultra-fine cement with liquid additives, polyurethane resins, and water-glass-based liquids can be used as the injection liquid.
  • the first two injection liquids mentioned above are fresh Condition water-soluble, so that empty injection hoses and devices can be cleaned by rinsing with water and are then perfectly available again for any subsequent injection.
  • the polyurethane resin is not water-soluble, so that cleaning the injection hose 1 is difficult; this injection resin should be re-injected within the drip time, i.e. before the polyurethane is stiffened.
  • Different injection liquids can of course also be used for the individual pressings. When in contact with water, the injection resin can also increase its volume by swelling, which provides additional security against later expansion of the joints, for example by settlement.
  • construction joints with a width greater than 0.1 mm can be sealed.
