Definitions

  • Method for repairing building structures, objects, in particular channels which are defective in terms of statics and water resistance, pipelines without disassembly
  • the invention relates to a method for the repair of building constructions, which can be used economically and reliably, particularly in the repair of statically, dynamically and / or channels of any size, from any raw material, without breaking open, in terms of water resistance.
  • the Hungarian method SUPERAQUA is known dimension (see Hungarian patent description No. 1095/84), where the repair is carried out with chemicals.
  • the faulty water-permeable channels are repaired by first filling the channel with an "A” reagent solution, and as soon as the solution level in the well does not or only slightly decreases, the first filled solution is pumped out and a second " B "Reagent solution filled in the channel section.
  • the "B” solution mixes with the previously injected "A” solution and, after a predetermined period of time has hardened, the gel gels into the cracks and through them into the cavities, floor passages around the channel.
  • the above method requires a significant amount of the reagent solution when repairing climbable and walkable channels. Accordingly, a large number of container wagons is essential, which is associated with additional costs.
  • NETRYN is only suitable for the repair of punctiform damage to channels with a circular profile. It can only be used for circular channels with a light width (inside diameter) of 20-60 cm.
  • the main characteristic of the above method is that a mat impregnated with synthetic resin is inserted into the channel.
  • the feed material is pressed against the inner wall of the channel with water pressure. Subsequently, the water temperature increased to 80 C, the lining material hardens on heat.
  • the aim of the present invention was to eliminate the deficiencies of the known repair processes, i.e. to develop a process with the aid of static, dynamic and / or channels of any format and of any size, faulty in terms of water resistance, of any raw material (which can be climbed and walked on), economically, reliably and without breaking open permanently, in view of the dynamics and / or water bulkiness can be repaired perfectly.
  • the solution according to the invention is defined in claims 1-7.
  • the channel repaired using the method according to the invention is at least equivalent in terms of dynamics, statics and / or water resistance to a newly installed channel, even after our experience is better.
  • Excellent properties of the method according to the invention are evident in numerous fields of application, but it is of the utmost importance in the repair of defective channels with an oval profile with a light range of 70/105, 80/120, 90/135, 100/150, 120/180 , 140/210 cm or more, or in the case of channels with a circular profile with a light width (inner diameter) of 100 cm or more, as well as in the case of channels of different dimensions and of different basic materials, with a mouth cross section, a pressed mouth cross section, a parabolic cross section and a dragon profile.
  • the method according to the invention can be implemented in numerous implementation forms.
  • FIG. 1 shows the repair of a channel with an oval cross-section
  • FIG. 2 shows another possibility of repair
  • FIG. 3 shows another possible embodiment
  • Figure 4 shows an example of the repair of the A ⁇ -formleitu ⁇ ge ⁇ while maintaining the function during the repair work.
  • FIG. 2 A possible manner of repair according to the invention is shown in FIG. 2.
  • the section of the sewer to be repaired (eg a 100 m section between two shafts) is shut down with the connecting lines as required. Subsequently, the channel section is cleaned with a high-pressure water jet - manually and / or mechanized - accordingly, on the inner wall of the a ⁇ alwa ⁇ d 1 and in the accessible Cracks, cavities 2, the loose structural parts are removed.
  • the cracks 2 of the channel wall 1 and thereby the cavities around the channel the defects of the channel wall up to the size of the original profile are mechanized and / or manually injected with a material 3 , filled out.
  • the 1 meter long, prefabricated, wear-resistant, watertight cuvettes 4 which are connected to one another in a watertight manner and are embedded in the mortar, correspond to the strength and smoothness together with the 15-20 cm wide Netlon net strips 7 with a mesh size of 2-2.5 cm arranged.
  • B 400 corresponds, has, and results in a smooth surface, is crack-free and tight and satisfies the requirements in terms of statics, dynamics and durability.
  • FIG. 1 Another possible embodiment is illustrated in FIG. 1
  • the subtitle of the duct wall 1 is assembled from prefabricated elements 4 and 13.
  • the course of the repair work is normal. gens coincides with that described in connection with FIG.
  • Task operation of the drain pumps, removal of provisional lines, etc.
  • a connecting line 9 is terminated in the vicinity of the duct section to be repaired with a pipe closure 10.
  • the pipe closure 10 is provided with a transfer pipe 11 which can be opened and closed and which - according to the respective need - is connected to a pipe 12 or a hose of the required length and size * .
  • the transfer pipe 11 is opened, the water flowing in the connecting line flows via the pipe 12 into the prefabricated kettle 4, since the channel can be kept in operation up to the upper height of the collar 4, even if the mortar layer 5 has not yet been applied to the inner surface of the channel wall 1.
  • the absorption of the shear force can be achieved in numerous other ways.
  • the prefabricated elements 4 are produced in such a way that at the connection points 6 the edges of the elements should not run perpendicularly on the channel wall 1 but one element at an angle of 30 ° downwards, the other upwards with respect to the vertical be arranged. This would create two different profiles that would be installed alternately. In this case, the synthetic network 7 is unnecessary.
  • the possible composition of the mortar or the door-locked material 5 according to FIGS. 2, 3 and 4 is as follows:
  • the materials are placed in a mixer in the following order, following each addition the contents of the mixer are mixed for 0.5 minutes:
  • the material is then mixed well for a further 1 minute (start of setting: after 2.75 hours, end of setting: after 4.0 hours).
  • the repaired sewer has the same quality - or even better - in terms of statics, dynamics and water resistance than that of a newly installed sewer.
  • the materials used for repairs, chemicals are inherently harmless, so the end product, so the repaired sewer is harmless overall and environmentally friendly for health.
  • the prefabricated profiles used for the repair and the door-locked material applied to the inner surface of the channel are completely bound to the wall of the old channel, so that cooperation is guaranteed.
  • the smoothness of the inner surface of the repaired duct is advantageous from the hydraulic standpoint, and the wear resistance is excellent.
  • the repaired sewer is resistant to mechanical and hydraulic sewer cleaning. Tightness, bending, compression and tensile strength, modulus of elasticity, inertia, heat resistance and resistance to aggressive and industrial water are excellent.
  • the cross-section of the channel profile is only minimally reduced, almost negligibly. For example, a channel with an oval profile, with a light width of 80/120 cm, is reduced by only 2 cm each.
  • the method is ideally suited for the repair of canals, various objects, basins, etc. made of any basic material and of any shape (brick, stone, concrete, reinforced concrete, earthenware, cast iron, asbestos cement, etc.).
  • the sewage is lifted from the connecting pipes of the houses and main pipes without difficulty and at particular cost, since the künet ⁇ ten can be put into operation within a short time.
