Injection Resins for Tunnels & Mines

  • Polyurethane Injection System

    • PU 2K 1601
    • PU 2K 1604
    • Colossus® PU 2K 1601 is a  quick reacting two component polyurethane injection resin for durable sealing and stabilization of dry and water – bearing zone in rock mass , dams , tunnels , canals , shaft and soil below the foundation . Colossus® PU 2K 1601 is characterized by it’s short reaction time, and high final strength , it shows slight foam formation when mixed with water .

      Given free expansion material increases it’s volume by about 3 times. The reaction mixture cures with out foam formation to form a pore free , compact and highly solid material if it does not come in contact with water and renders the structure watertight. Reacts with water forming a rigid hydrophobic foam that encapsulates grains of soils. Colossus® PU 2K 1601 is used for ground stabilisation. Besides giving stability it is also often used to restrain water bearing layers in the soil.

    • Colossus® PU 2K 1604 is design for quickly stopping flowing water due to cracks , cavities and leaks. Colossus® PU 2K 1604 is also suitable for stabilizing non binding soil and as injection material for hydraulic base failures . Colossus® PU 2K 1604 is recommended as temporary sealing for foundation pits , water bearing joints and drilling holes.

      Colossus® PU 2K 1604 is a 2 Component PU injection foam resin which strongly expands and cures to form a semi rigid foam when mixing with water. Colossus® PU 2K 1604 only start reacting upon contact with water in foundation soil and therefore does not cure in the injection lance. Its reaction time can be adjusted to the desired reaction rate by adding up to 20 % of Accelerator.

    • Colossus® PN – 2K-230/12 is an air-driven, 2-comp.  injection pump with a fixed mixing ratio for the application of products of the Colossus® Consolidation Line.

      • Delivery with counter-pressure (1:1 mixing ratio) -12 l/min ( 100 bar)
      • Maximum operating pressure 230 bar
      • Air consumption at 6 m³/min ( 212 CU ft /min).
      •  Maximum air intake pressure 8 bar  -
      • Total weight approx. 90 kg
    • The working principle of the Colossus®   PN – 2K F1  is based on two  regenerative, air-operated piston pumps. A compressor with an air  output of 200 – 400 l/min. is required for operating the pump. The  individual components are introduced to the mixing head separately.  The actual mixing process is implemented by means of a static mixer located in the mixing head. Check valves prevent the components from flowing back into the feed tubes and thus avoid all accidental reactions within the feed system.

    Foam HG

    Foam HG is a high performance foaming agent, formulated with special natural polymers and biodegradable anionic surfactants. It produces very stable foams and can be used both with clean and salted water, even with high hardness and is characterized by minimal environmental impact.

    Foam HG has a high strength and good lubricating properties, improve substantially the carrying capacity of the resulting materials (debris) allowing, thus, obtaining a cleaner excavation area. Such benefits may also increase with small additions of polymer Acryl 46. It can be injected into any type of terrain, including fractured and very permeable, prevents agglomeration of the clay and prevent blockages in the shield and in the chamber excavation of EPB machines. it reduces, thanks to the power of lubrication, the friction between the soil and digging equipment, significantly lowering the level of wear and increasing the efficiency of the machine.  It lends itself also as a valuable additive against dust, especially during excavations in the coal mines. Foam HG is quickly biodegradable and not pollutant for environment.

    DOSING

    Foam HG should be mixed with water in concentrations ranging from 1,5% to 4%, according to the conditions of excavation and soil type and the types of foam generator.

    In each case the values of expansion foam should be developed on site to verify the correct ratio between foam injected and the excavated product according to the various conditions of pressure.

    In principle, one can establish the following concentrations:

    as a foaming agent (to EPB)

    •  normal ranges: 1.5% – 3%
    •  below the water table: 3% – 4%

    As an agent against dust: 4.3%
