Fire safety bulkhead separation type evacuation passage {BULKHEAD SEPARATION TYPE EVACUATION PASSAGE}

The present invention relates to a partition-separated evacuation passage for enabling safe evacuation by securing an evacuation space and an evacuation passage in the event of an emergency such as a fire in a tunnel, and more particularly, because it is easy to install in a tunnel, so that the construction period It is about a fireproof safety bulkhead-separated evacuation passage that can shorten the

In accordance with the recent Ministry of Land, Infrastructure and Transport’s guidelines for the installation and management of road tunnel disaster prevention facilities, when a fire or other accident occurs in a tunnel with a high risk of leading to a major accident, road users facing an accident are moved to a safe area. A bulkhead-separated evacuation passage must be installed to induce evacuation.

In other words, the bulkhead-separated evacuation passage is installed on the side wall inside the main tunnel and the branch tunnel to block smoke and heat in case of fire with a non-combustible bulkhead, and to secure a safe escape passage space from fire.

As shown in FIG. 1, this bulkhead-separated evacuation passage is separated from the road in the tunnel (1), and a concrete bulkhead (2) is poured on-site to secure a passage space (3) with a minimum width of 0.75 m or more and a height of 2 m or more. It is installed in the way of making it or assembling precast concrete.

However, in the case of the concrete bulkhead 2, there was a problem in that a lot of cost and construction period were required because the formwork installation and disassembly and the concrete curing process had to be performed.

In addition, since the conventional concrete bulkhead structure cannot look out from within the aisle space 3, it is very difficult for users to quickly determine an emergency situation by themselves and take appropriate countermeasures such as evacuation.
