Composite underground corridor fireproof isolation device and method

Abstract

The invention discloses a composite underground corridor fireproof isolation device and method. A composite underground corridor comprises an underground corridor body and a connection passageway. The underground corridor body is communicated with an urban underground quick tunnel through the connection passageway. The two side walls of the connection passageway are provided with a side wall air exhaust passageway body and a side wall air supply passageway body respectively. The side wall air exhaust passageway body comprises an air exhaust shaft. An air exhaust device is arranged in the air exhaust shaft. The side wall air supply passageway body comprises an air supply shaft. An air supply device is arranged in the air supply shaft. The lower end of the air exhaust shaft is communicated with the lower end of the air supply shaft through the connection passageway. Both the upper end of the air exhaust shaft and the upper end of the air supply shaft are communicated with the ground. By means of the composite underground corridor fireproof isolation device and method, smoke mixing in the urban underground quick tunnel or the underground corridor under the fire working condition can be avoided effectively, fire fighting vehicles are not affected when passing through the connection passageway, the fire rescue efficiency and reliability are improved remarkably, and the composite underground corridor fireproof isolation device and method have the advantages of being low in construction cost, convenient to construct, short in cycle, high in benefits, low in maintenance cost and the like.

Description

technical field [0001] The invention relates to tunnel ventilation, in particular to a compound type underground ring corridor fireproof isolation device and method, which is suitable for the fireproof separation between urban underground fast tunnels and underground ring corridors. Background technique [0002] With the development of the national economy, the urban transportation industry has developed rapidly, and the construction of urban underground transportation roads has also advanced by leaps and bounds. The underground ring corridor is a new type of urban underground traffic road that has emerged in recent years. It is an underground public passage built under the road and equipped with independent entrances and exits to connect the garages of various plots. It is usually in the shape of a ring. [0003] The composite underground ring corridor usually refers to the underground ring corridor combined with the urban underground fast tunnel. There are a series of fir...
