Definitions

  • the invention relates to a system technology consisting of the process instructions and an active ingredient used for solidification, hereinafter referred to as "soil stabilizer", for use of non-construction suitable frost-prone, fine and mixed-grained mineral soils and their conversion to durable + resistant + frost-resistant + high-carrying foundation , Load-bearing, bedding and filling layers in construction.
  • the DE 26 33 749 A1 describes a soil stabilizer for soil stabilization based on epoxy resin ester.
  • a plasticizer Alkylsulfonester is specified. After the addition of the soil stabilizer, compaction and, in particular, curing of the epoxy resin-treated soil must be carried out to obtain a stable, consolidated soil layer.
  • the DE 44 28 269 A1 describes an impregnation soil stabilizer for soil consolidation based on polyvinyl esters. This document discloses plasticizers based on alkylsulfonic acids.
  • the DE 195 09 085 A1 discloses a plastisol composition. Plasticizers based on alkyl sulfonic acid esters are described, and it is stated that coatings of a general type can be made with this type of plastisol composition.
  • the DE 10 2004 031 039 A1 discloses a method for soil consolidation in which several additives in the form of polyelectrolytes, preferably polymers or copolymers based on acrylamide, and a hydraulic binder or a bitumen emulsion are applied to the soil to be consolidated and mixed with the soil. This is followed by mechanical compaction of the soil.
  • the invention has for its object to improve a system technology for soil stabilization, consisting of a procedure and a soil stabilizer, in terms of process flow and cost to achieve a permanent indestructible improvement in the soil properties of fine-grained and mixed-grained, cohesive soils.
  • a preferred field of application of the invention is the implementation of the method and the application of the soil stabilizer as highly load-bearing and frost-resistant foundation, support, bedding and filling layers in building construction, in road and road construction and in earthworks and civil engineering.
  • the application is generally valid for new buildings and also for renovations.
  • a particularly favorable application of the invention relates not only to road construction, but also to building construction.
  • foundations are used, which are used as foundation pads for floor slabs of buildings. If no viable layer is present in the foundation level of a building, the stabilizer according to the invention is also used for the consolidation of the substrate.
  • stable backfill layers can also be produced in building construction, e.g. serve to fill up excavated excavations.
  • Such stabilized filler layers are also used in pipeline construction for covering the pipelines installed in the ground.
  • Existing structures can also be drained by partially excavating the soil previously installed in the excavation area and re-installing it after treatment with the soil stabilizer according to the invention.
  • Another important application of the present invention is in the treatment of moats in which the sole or slopes are susceptible to erosion. Also in this case, the sole or embankments of moats can be secured and sealed against erosion by treatment with the soil stabilizer of the present invention.
  • the soil stabilizer of the invention is even suitable for the production of blocks or other solid structures in a modular design.
  • a soil treated with the stabilizing agent is pressed into molds and subsequently the building blocks, structural elements or other modular building elements thus produced are used for further construction in civil engineering. These elements are then particularly waterproof, highly resilient and protected against ingress of moisture.
  • the use of the soil stabilizer according to the invention is also suitable for dyke construction or dyke restoration. It can both the entire structure of a dike or even water-stressed parts of a dike (such as the sealing apron) are protected against ingress of pressurized water.
  • An essential feature of the soil stabilizer is that a permanent reduction of the water binding forces of the fine soil components of these soils is achieved by a soil stabilizer acting as an ion exchanger and catalyst.
  • the soil stabilizer used is a slightly water-soluble, clear liquid whose chemical composition is a mixture of different sulfonic acids + special additives + water.
  • the viscosity is oily.
  • a major constituent of the active ingredients of the soil stabilizer is a mixture of various sulfonic acids which share the common functional group -SO 3 H linked to a water repellent organic component R.
  • the representation is: R - SO 3 - H.
  • the sulfonic acids dissociate in water.
  • the soil stabilizer of the invention acts as an ion exchanger and catalyst in the soil.
  • the soil stabilizer causes the hydrogen ions H +, (and thus the water attached to these ions via hydrogen bonding), which are adhesively bound to the surface of the soil particles, to be displaced and replaced by (+) metal ions present in the water shell, e.g. Na +; K +: Mg ++; Ca ++; AI +++;
  • the soil stabilizer according to the invention furthermore has the effect that the (+) metal ions bound to the soil particles can no longer accumulate water of hydration by combining with the (+) metal ions in the acid-residual ions contained in the soil stabilizer. It is therefore a reduction of Adsorbtionswasserhülle by an ion exchange mechanism.
  • the acid-residual ions contained in the soil stabilizer and attached to the metal ions are linked to a hydrophobic organic moiety.
  • the hydrophobic components cause that in the compacted soil no more water can be transported in the pore space.
  • the hydrogen ions H + released during dissociation in the soil stabilizer according to the invention react directly with the hydroxyl ions OH - present in the water shell to form hydronium ions H3O + and in a further step to water H2O. Thus, the acid effect is eliminated and neutralization has occurred.
  • the soils treated with the soil stabilizer may contribute to the optimum soil water content required for compaction the same compaction work to higher density of dry compacted than not treated with the soil stabilizer soil.
  • the hydrophobic (water-repellent) constituents of the soil stabilizer cause capillary water rise to be prevented in a soil treated and compacted with the soil stabilizer in accordance with the instructions for use and the penetration of water into the compacted soil body is prevented at all.
  • clay silt (also called silt or dust sand), mineral mixtures of stones, gravel or sand, each with admixtures of more than 15% by mass of silt and / or clay: such as clayey sand, silty sand, clayey silty sand, clayey gravel sand, silty gravel sand, clayey silty gravel sand, loam (mixture of fine sand + silt + clay), natural or broken rock mixtures.
  • silt also called silt or dust sand
  • mineral mixtures of stones gravel or sand
  • the soil stabilizer according to the invention can generally be used in construction, in particular in road construction and road construction, earthworks and foundations for the purpose of solidifying the frost-prone, fine-grained and mixed-grained loosened rocks.
  • These mineral soils no longer have to be removed from the construction site as before and replaced by frost-proof mineral mixtures (as antifreeze layer, gravel base layer, gravel layer). Rather, the soil present on the construction site is treated on site with the soil stabilizer and, after subsequent compaction, converted into permanently resistant + frost-resistant + highly loadable construction layers.
  • Soil mechanical classification of the suitable soils to be treated with the soil stabilizer For optimum success in the application of the soil stabilizer, the mineral soils to be used must have the following soil mechanical properties A + B + C + D, which are determined in soil mechanical laboratory tests. The predominant soils are suitable for solidification with the soil stabilizer.
  • soil stabilizer is of great advantage in areas that do not have suitable rock resources to produce frost-resistant, sustainable rock mixes for base courses.
