Description
Technical field
The present invention relates to a kind of vertical evacuation structure of tunnel, particularly a kind of vertical evacuation structure of subterranean tunnel.The invention still further relates to the subterranean tunnel of vertical evacuation structure with this subterranean tunnel.
Background technology
Fire is the emphasis disaster type that the roads and tunnels disaster prevention system is taken precautions against.Grow up the tunnel evacuation and the rescue difficulty bigger, in case breaking out of fire possibly cause bigger economic loss and social influence.Based on the principle of " people-oriented ", one of key technology of the anti-fire system of roads and tunnels is to guarantee evacuating personnel, fire-fighting and rescue safety, efficient.
The general evacuation rescue pattern that adopts in tunnel has three kinds: transverse mode, horizontal vertical binding pattern and vertical pattern.Transverse mode is meant and utilizes horizontal UNICOM road, is evacuated or rescue to another tunnel, hole by tunnel, a hole; Vertical pattern is the special-purpose escape way in tunnel to be set evacuate longitudinally and rescue; The pattern of horizontal vertical combination is the aggregative model that two kinds of facilities are set.Composite factors such as tunnel characteristic, engineering construction condition, ancillary facility level are depended in the selection of three kinds of patterns.Find that through the domestic and international project case is investigated external roads and tunnels adopts horizontal or vertically single evacuation rescue pattern mostly, domestic then three kinds of patterns all have Engineering Projects.In the design in the tunnel of growing up, progressively pay attention to the important function of vertical escape way in fire rescue in recent years.
Gulf, Tokyo undersea highway tunnel has adopted the mode of evacuating longitudinally entirely, between two shield tunnels transverse passage-way is not set.Tokyo Bay undersea highway tunnel geological conditions is similar with Shanghai; Be weak Fu Shui stratum; Risk when constructing for reducing; And when avoiding earthquake because the inconsistent infringement that causes transverse passage-way connecting portion tunnel agent structure of phase place of adjacent tunnel, surpass between two tunnels of 9km in length and not establish transverse passage-way.The tunnel utilizes space under the lane plate as escape way, whenever at a distance from 300m one place's slide escape and fire fighter access is set, the about 30m of two access spacings, and indicate the emergency exit with tangible sign in roadway one side.Yet, the special-purpose battery truck that personnel and the evacuating personnel of depositing in tunnel internal are used that can only pass through of this escape way, fire-fighting vehicle can't be from the tunnel outside the entering.
Find through investigation; Driver and crew evacuate and the fire-fighting and rescue pattern is employed in the pattern that closely spaced horizontal walkway is set between two tunnels more during fire in the world; Consider the high risk of implementing People's Bank of China's transverse passage-way in the soft stratum of Shanghai; The Shanghai Urban roads and tunnels adopts the People's Bank of China's transverse passage-way and the pattern of vertically fire escape combination to reduce the quantity of People's Bank of China's transverse passage-way more; Fire-fighting is through People's Bank of China's transverse passage-way rescue, and driver and crew are through People's Bank of China's transverse passage-way and vertically fire escape escape, but the rescue efficiency that exists People's Bank of China's transverse passage-way spacing to strengthen the back fire-fighting reduces, vertically fire escape lacks the fire fighter effective evacuation and rescue; Driver and crew's evacuation is in disordered state, very easily causes personnel's injures and deaths.
Therefore, those skilled in the art is devoted to develop a kind of vertical structure and method of evacuating rescue of large-scale shield tunnel lower floor's idle space tissue of utilizing, and with effective raising fire-fighting, rescue efficiency, sets up effective evacuation system.
