Definitions

  • the present invention relates to a system for the insulation of tunnels, rock cavities and similar mining installations, in conjunction with which a draining layer and a waterproof membrane are installed immediately adjacent to the rock or on the surface of a reinforcing layer applied thereto, so that they follow the contours of the rock or the reinforcing layer.
  • the invention also relates to a method for implementing the insulation system for the insulation of tunnels, rock cavities and similar mining installations, in conjunction with which a draining layer and a waterproof membrane are installed immediately adjacent to the rock or on the surface of a reinforcing layer applied thereto, so that they follow the contours of the rock or the reinforcing layer.
  • ice encroaches upon the free clearance for the vehicles in rail and road tunnels, for example. This results in disruptions to the traffic. As the air temperature rises, the ice thaws and drops down. Equipment, vehicles and people, etc., can suffer damage and injury.
  • Ice clearance work is both dangerous and costly. Deaths have occurred in Sweden in conjunction with ice clearance. Considerable sums are spent every year on ice clearance work. Ice clearance usually means that a road tunnel, for example, must be closed either completely or partially. The result is the disruption of traffic.
  • insulated vaults made of plastic and sheet metal are installed inside tunnels.
  • the disadvantages associated with these vaults are, for example, that they require a certain amount of space, which means that an increased tunnel cross-section must be blasted, or that inroads must be made on the free space for the traffic, for example. They are also expensive, and they involve long delivery and installation periods (prefabrication for different sizes of tunnel).
  • the fire prevention authorities have also begun to adopt a negative attitude towards plastic vaults in traffic tunnels where vehicle fires, for instance, can occur. Extruded cellular plastic matting (AT-B-370 850) has also been used.
  • this system exhibits the same disadvantages as those outlined above for the vaults.
  • Experiments have also been conducted into heating the air, in this way preventing freezing. This is a very expensive method, however, and is susceptible to plant breakdown. Insulated drains are sometimes used locally. More often than not these produce a poor effect, since any water leakage due to blockages has to be removed from the area which has already been drained by the drains. Furthermore, such local applications provide poor protection against the cold.
  • the principal object of the present invention is thus to prevent ice formation and to permit the advancing water to be led away in a drainage system.
  • the invention must take up the smallest possible space, require a short installation period and be flexible (ease of adaptation to other tunnel cross-sections, etc.).
  • the invention must also be suitable for use not only for the complete insulation of a timing installation, but also for the partial insulation of an installation.
  • the rock itself maintains a comparatively even temperature of about +5°C throughout the year.
  • the water which finds its way through the fissures in principle exhibits the same temperature as the surrounding rock.
  • the aim of the invention is thus to prevent the cold air from cooling down the rock and the water.
  • Said object is achieved by means of a method in accordance with the present invention, which is characterized essentially in that thermal insulation to counteract frost is installed on the surface of the waterproof membrane, and in that fire-retardant insulation is installed on the surface of said thermal insulation.
  • a further object of the present invention is to disclose a method for making available a system for the insulation of tunnels, rock cavities and similar mining installations, in conjunction with which a draining layer and a waterproof membrane are installed immediately adjacent to the rock or on the surface of a reinforcing layer applied thereto, so that they follow the contours of the rock or the reinforcing layer.
  • Said further object is achieved by means of a method in accordance with the present invention, which is characterized essentially in that thermal insulation is installed on the surface of the waterproof membrane for the purpose of counteracting frost, and in that fire-retardant insulation is installed on the surface of the thermal insulation.
  • the invention consists of a number of components which are combined to produce a system for the frost insulation of mining installations.
  • the system consists of the following components and is composed in the following manner.
  • Installed immediately adjacent to the rock 1 or on the outside of a reinforcing layer 2 are, on the one hand, a draining layer 3 and, on the other hand, a waterproof membrane 4.
  • the water is led away via the draining layer 3 to a drainage pipe which takes the water out of the installation.
  • the draining layer 3 and the waterproof membrane 4 are installed close up against the rock 1 or the reinforcing layer 2, so that they follow the contours of the rock, requiring a minimum of space.
  • This method has been used for many years for the removal of water, in so doing preventing dropping water and running water, etc., although no frost insulation is achieved in this design.
  • a reinforcing mesh 5 can be attached to the surface of the waterproof membrane 4.
  • Thermal insulation 5 consisting, for example, of polyurethane is then applied by spraying or by some other appropriate method.
  • the reinforcing mesh 5 functions, where it is used, as a reinforcement inside the insulating layer, in this way producing a stable, insulating layer.
  • the thickness of the insulation is simply varied depending on the air temperature with which the system is required to contend.
  • a fire-resistant material 7 is applied to the outside of the thermal insulation 5, 6 in order to provide fire-proofing.
  • the nature of the fire-resistant layer 7 may vary to suit the various requirements of the fire prevention authorities.
  • a thin layer of fire-retardant plaster can usually be applied on the outside of the thermal insulation 5, 6.
  • the frost insulating system thus consists of a number of components, all of which are available by length or by weight.
  • the system is built up simply directly on site and can be adapted to suit different tunnel cross-sections and different requirements, etc. As it follows the contour of the rock, a minimum of space is required.
  • the method by which it is applied is also suitable for systematic handling, so that not only entire mining installations, but also parts of mining installations can be insulated.
