Definitions

  • the invention relates to a method for waterproofing soil and / or soil and, in particular, to soil or soil , due to their internal dimensions of inaccessible pipelines and channels, which can be carried out without digging out the lines or channels, and also to improve the durability of building objects.
  • terms such as “building object”, “sewer”, “pipeline” are understood in the broadest possible sense. They can refer to channels and pipelines of different materials, ages, different sizes and purposes, also to open or closed pools, shafts, water towers, tunnels, cellars, rooms, natural or artificial caves made of different materials .
  • the liquid B mixes with the remnants of the liquid A, and after a certain time the material solidified in the cracks and cracks in the damaged channel and through it into the surrounding earth to a gel and hardens.
  • the procedure is widely used in Hungary and abroad.
  • this method also has disadvantages, for example, when repairing accessible channels, it must be taken into account that a large amount of chemical solution; and therefore many tank vehicles are needed - which is complex. It can also happen that, especially in the case of coarse-grained, gravelly soils, the -. There is a risk that chemical solutions can enter the groundwater from channels in the groundwater or that the water escaping from the damaged areas of the channel can seep down to the groundwater, which can cause groundwater contamination.
  • the object of the invention was to eliminate the deficiencies listed, ie ⁇ to create a perfected method which offers a more economical, faster, more reliable and more environmentally friendly solution.
  • the known repair method described was used, in which a liquid A containing water glass was introduced into the soil to be treated and, if necessary, reacted with a liquid B in the soil, a hydrogel being formed Developed further according to the invention in that, before or during the introduction of the liquid A into the soil to be treated, it is treated with the aqueous suspension of a hydraulic binder.
  • This suspension is also referred to below as liquid C.
  • the liquid C contains cement, preferably heterogeneous Portland cement, and optionally setting time regulators and / or substances which prevent settling. Fine powders with a grain size of at most 400 microns industrially produced from natural materials are preferably used as the substances preventing settling. It is further preferred the liquid C to add industrial waste materials, for example fly ash.

Abstract

Au cours du procédé décrit, on introduit dans le sol à traiter un liquide (A) contenant du verre soluble, que l'on fait réagir avec un liquide (B) également introduit dans le sol, afin de former un hydrogel. Ce procédé est caractérisé en ce qu'avant ou pendant l'introduction du liquide (A) dans le sol à traiter, ce dernier est traité avec la suspension aqueuse d'un liant hydraulique (liquide C).
