Description

Flue gas diffusion system for underground pipe gallery
Technical field
The present invention relates to machinery fields, relate more specifically to a kind of flue gas diffusion system for underground pipe gallery.
Background technology
Currently, after catching fire due to underground pipe gallery, have the characteristics that the intensity of a fire is quickly spread, generally the side by the way that fire wall is arranged Formula, to prevent fire spreading, and it is using fire-proof sealing material that the gap wall and pipeline is tight at fire wall in pipeline It is close to tamp.Concrete norm requires such as:《City integrated piping lane engineering legislation》(GB 50838-2015), the 7.1.6 articles " day Right feed channel cabin and accommodate power cable cabin should every 200m using not so property wall of the fire endurance not less than 3.0h into Row fire separation.Door at fire separation should use first class fire resistant doorsets, traversing pipe line fireproof partition position that should use fire retardant package etc. Fireproof blocking measure tightly block ".
Meanwhile the characteristics of according to underground pipe gallery linear water drain, generally use open drain is drained.Concrete norm requirement Such as:《City integrated piping lane engineering legislation》(GB 50838-2015), the 7.6.1 articles " automatic row of pipe gallery planted agent setting Water system ";The 7.6.2 articles " the draining siding-to-siding block length of pipe gallery is not preferably greater than 200m ";The 7.6.4 articles " bottom of pipe gallery Open drain is preferably arranged in plate, and pipe gallery internal water accumulation should be imported collecting gutter by open drain, and the gradient of open drain is not It should be less than 0.2% ".
Generally ponding is imported after catch pit by gutter in existing underground pipe gallery project, in underground gallery and is arranged by pump Go out, fire wall is generally directly passed through in gutter.But since open drain belongs to the drainage system of open type, once fire occurs Calamity, even if carrying out comprehensive closure to the hole at fire wall, flue gas even combustible will diffuse to fire prevention by open drain Security risk is caused to reduce the fire protecting performance of fire wall in the wall other side.And the underground pipe gallery of shield form is used, Often in 600m or more, this also will result in the open drain between two active wells and need to pass through the spacing of its active well and active well The problem of multiple tracks fire wall, this is also the peculiar situation in the project of underground gallery.
In addition, the big feature that fire occurs for cable tunnel is that fire water drainage amount is smaller.General power cable tunnel or comprehensive It closes in piping lane using ultrafine dry powder extinguishing installation, high-pressure fine spray extinguisher and the fire-fighting fire extinguishing side for only arranging fire extinguisher Case.These fire protections, have fire water drainage amount it is smaller even without draining the characteristics of.
In conclusion when fire occurs for underground pipe gallery, for preventing flue gas from diffusing to neighbouring fire prevention point by gutter Requirement of the requirement in area higher than draining ditch water discharge.
Currently, not occurred in existing engineering, substantive effective measures go to improve or solution underground pipe gallery catches fire The problem of flue gas is spread by open drain afterwards.Therefore, a kind of flue gas diffusion system for underground pipe gallery is badly in need of in this field, So that when fire behavior occurs, which can cut off rapidly the gutter of fire wall both sides, to which effect prevents flue gas from passing through draining Bright ditch diffuses to the fire wall other end.
