North River Tunnels Ventilation Facility

Skanska, as part of a joint venture, was awarded a $25 million contract by Amtrak to reconstruct and upgrade existing shaft facilities serving the two North River Tunnels at Weehawken, N.J. The existing ventilation facilities

Tunnel Dampers and the Piston Effect

Tunnel dampers are volume control dampers that are built to withstand the intense conditions of tunnel air flow. They can be used for a variety of applications within a tunnel HVAC system, including air intake and exhaust.

Three Miners Trapped Underground At

A second collapse then blocked the tunnel and cut off communication with the surface. Company officials said the underground emergency shelter has enough supplies for "an extended stay," with the capacity to sustain about 16 people

LED Tunnel Lights: Simple Guide for Better Tunnel Lighting

Tunnels are important parts of our roads and cities. They help people travel safely under water, through mountains, or under busy streets. Good lighting in tunnels saves lives. It helps drivers

Practical methods for constant temperature control in tunnel

After evaluating four typical tunnel ventilation schemes, this study proposed achieving effective constant temperature control in TSFs using the most feasible approach, i.e., supply-air-based

Long distance tunnel ventilator fan in action at tunnel project

2025-07-09 We are excited to showcase the latest site video of our long distance tunnel ventilator fan operating at a large tunnel excavation site. The tunnel has already reached 1,000 meters,

Over 19 hectare of Sanjay Gandhi National Park forest land

The state government has claimed that while the land has been handed over to the BMC for tunnel construction, the legal status of the transferred land will continue to remain ''forest land''.

Numerical Study on Smoke Characteristics in Ultra-Long Tunnels

Metropolitan city express line tunnels are fully enclosed and often span long distances between stations, allowing multiple trains within a single interval. Traditional segmented ventilation

Mandeville Road Headhouse

Headhouse construction Currently, works are ongoing to build the ventilation shaft and satellite shaft with works to build the headhouse building planned from early 2025. A ventilation shaft, or vent shaft, is the vertical

Study on Smoke Flow and Temperature Distribution Patterns

Zheng Anping [11] investigated the ventilation modes and fire linkage modes of domestic subway stations, studying the principles of fire ventilation linkage modes in subway tunnel sections.
