Description
Technical field
The utility model relates to railway tunnel, and particularly a kind of two-wire closes the Incorporated Rescue station of repairing bridge tunnel adjoining tunnel group location.
Background technology
Along with China railways is in the tremendous development of western mountainous areas, because of very difficulty of orographic condition, emerge the intensive tunnel group of a large amount of specialities.Continuously between the adjacent hole of adjoining tunnel, exposure open-wire line length is too short, and fire train carries out and need consider the adjacent tunnel that affects each other while taking precautions against natural calamities rescue at Portal Section, is considered as tunnel group.If tunnel group length exceedes 20km, need the Rescue Station of taking precautions against natural calamities is set, the distance between Rescue Station is not more than 20km.
The traditional method for designing of Rescue Station is that the position of service gallery arranges in most integrating tunnel, under train fire emergency mode, can meet personnel from fire incident tunnel rapid evacuation to hole in safety zone, and can rescue to hole.Although rescue station is set in hole also can meets the requirement of personnel escape and fire suppression, but its setting position is mostly far away apart from hole, external rescue is waited in the safety area that personnel can only escape in tunnel, be difficult to be dispersed on foot outside hole, in addition in hole, light is relatively poor, very easily cause indicator of trapped personnel psychology panic, and it is mutually crowded to cause escape personnel, causes the dead group of group to hinder the generation of accident.In addition, the Rescue Station arranging in hole need arrange a large amount of ventilation smoke exhaust facilities and other rescue facility of taking precautions against natural calamities, and fire smoke can be got rid of outside hole, because the supporting rescue facility of taking precautions against natural calamities is more and comparatively complicated, regular maintenance difficulty is large, and operation, management cost is relatively high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of two-wire and closes and repair bridge tunnel Incorporated Rescue station, effectively to strengthen evacuating personnel efficiency and evacuation safety.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Two-wire of the present utility model closes repaiies bridge tunnel Incorporated Rescue station, comprises tunnel, upstream, tunnel, downstream and is positioned at two-wire bridge between the two, it is characterized in that: the both lateral sides of described two-wire bridge respectively arranges bridge and evacuates platform; In tunnel, upstream and/or tunnel, the downstream both lateral sides of closing on the Portal Section of two-wire bridge tunnel be set evacuate platform, and at the capable pilot tunnel of both lateral sides peripheral hardware horizontalization of corresponding Portal Section; Platform is evacuated in homonymy tunnel, bridge is evacuated platform and joined, and arranges the horizontal evacuation service channel that platform is communicated with is evacuated in parallel homonymy pilot tunnel, tunnel at Portal Section along circuit bearing of trend interval.
The beneficial effects of the utility model are, in tunnel, multiple-bridge tunnel connecting place arranges Rescue Station in conjunction with bridge open-wire line location, train fire compartment can be rested against to the outdoor location of open-wire line, utilize " buoyancy effect " that fire smoke density is little, realize to overhead natural draught system, can avoid flue gas to flow into harm personnel life security in tunnel, and can bring into play the advantage of outdoor location well lighted, to strengthen passenger the escape ability of saving oneself and the safety of evacuation; Within the scope of rescue station, double track tunnel Portal Section both sides, upstream and downstream are provided with and evacuate service channel and emergency exit, can guarantee that the passenger who extends to the non-fire compartment in hole directly escapes to hole from the parallel pilot tunnel of adjacent side, with the danger of avoiding personnel to evacuate in tunnel interior span railway line; Make full use of outdoor location, hole and be convenient to the advantage of natural draught system, can reduce the setting of the rescue facility of taking precautions against natural calamities, be conducive to save operation, management maintenance cost; And utilize hole open-wire line section well lighted, the short advantage of Travel distance, and be conducive to the ability that abundant evacuating personnel is saved oneself, avoid casualties, there are very significant economical, societal benefits.
