    Tunnel solutions for the light sensors

    According to the International Committee on Illumination CIE recommendations, luminance should be monitored as the luminance contained within in a conical field of view, subtending an angle of 20º. It is recommended that a luminance photometer is mounted in the tunnel approach road approximately 120 - 200 metres from the portal, depending on the approach speed of the vehicles and their stopping distance. The purpose of monitoring the luminance at the portal is to adjust the level of light intensity inside...

    Jaw bucket crushers for tunnels and enclosed spaces

    One-of-a-kind, and fitted with integrated systems for dust reduction, MB`s range permit crushing operations to be carried out in enclosed spaces and areas with limited ventilation. Tunnel digs, underground systems and industrial warehouses are no longer a limit for on-site recycling. The efficiency of the entire MB`s range is constant both for indoor and outdoor use. A clear advantage, confirming the versatility of the range.

    Tunnel solutions for the tunnel air flow

    Tunnel ventilation systems are designed to enable a sufficient throughput of air to be maintained to ensure a safe operating environment for users. These systems consume large amounts of power and need to be operated as efficiently as possible. To do this it is necessary to know the effectiveness of the system in terms of air flow and direction developed within the tunnel. The TunnelTech 301 is a single point ultrasonic flow monitor that is unaffected by traffic flow and sound reflections. It is designed to...

    Tunnel solutions for the extractive areas

    In some countries they do not allow tunnel atmosphere monitors to be mounted on the tunnel wall; also, where there is a single bore it is very difficult to gain access for maintenance purposes. The TunnelTech 400 series are extractive gaseous pollutant and visibility monitors and extract a gas and dust sample from the tunnel bore and carry to a remote analyser. This allows maintenance to take place without affecting tunnel traffic flow.

    Tunnel solutions for the gaseous pollutants

    The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205 use the same rugged corrosion resistant enclosures and have an optional Data Display unit. As there is only one moving part so reliability levels are very high and maintenance levels very low.

    Tunnel solutions for the visibility monitor areas

    The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail tunnel safety system. It monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead. The TunnelTech 102 Cold smoke monitor (CSM detects smoke from a fire to rapidly warn the operator of the hazard. Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the locus of the fire if it is...

    Ambient air quality monitoring solutions for tunnel monitoring

    Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.

  • Tunnel Structural Health Monitoring Systems

    Structural Health Monitoring allows rapid assessment of a tunnel’s state of health and such approach is becoming recognized as an appropriate mean to increase the safety and optimize operational and maintenance activities of tunnels. Data resulting from the monitoring program is used to improve the operation, the maintenance, the repair and the replacement of the structure based on objective results. Detection of ongoing damages can be used to discriminate deviations from design performance. Malfunctioning...

    Pore pressure variability and control is one of the most significant aspects of Geotechnical Engineering practice related to slope stability, underground openings, foundation of heavy structures, and water retention facilities. Pore pressure effects are most often controlled by natural small-scale hydrogeologic details. Characterization and management of pore pressures requires closely-arrayed repeated measurements to determine the effects of these details for design of appropriate mitigation measures, for...

  • Tunnel Construction and Underground Mining Industry

    Conventional methods of firefighting have their limits when it comes to extinguishing fires in tunnels and underground railway shafts. The build-up of smoke and soot is an enormous hindrance to firefighting. Then there is the intense heat and the low concentration of oxygen because of the inertization process. In most cases the extinguisher jet cannot reach every part of the source of the fire.
