Multichannel underground pipe gallery with ventilation escape mouth structure
The utility model is related to a kind of underground pipe gallery, more particularly to a kind of multichannel with ventilation escape mouth structure
Underground pipe gallery.
At present, multichannel underground pipe gallery needs to set ventilating opening and passway for escaping every a segment distance, to realize
Personnel can withdraw in time when the ventilation of pipe gallery and generation disaster.In view of the most inconvenience of the consideration of pavement facilities are directly vertical
Individually lead to road surface, and individually vertically lead to road surface, outlet is excessive, and cost is high, and ground landscape is poor, so using cross connection pipeline
The ventilating opening and escaping exit of each passage of multichannel comprehensive piping lane are connected, can saving construction cost, improvement pavement facilities.It is mixed according to rigidity
Xtah Crude Clay structure is as connecting pipe, when sedimentation occurs for ground or road vehicles are rolled, and easily causes bodies splittable, the feelings such as leak
Utility model content
Utility model purpose：The purpose of this utility model is to provide a kind of will be divulged information pipe for escaping by steel connection member
It is installed at the top of multichannel piping lane, and road surface will be led to after each ventilation pipe for escaping connection and is made with solving individually vertically to lead to road surface
Into cost it is high, ground landscape is poor the problems such as multichannel underground pipe gallery.
Technical scheme：Multichannel underground pipe gallery described in the utility model with ventilation escape mouth structure, including
The piping lane main body being made up of multiple passages, each passage passes through provided with ventilation escaping exit, ventilation escaping exit with ventilation pipe for escaping
Connection member is connected, and the connection member is bolt or/and shaped steel flange, and its top is connected with ventilation pipe for escaping, and bottom is buried
In in the armored concrete in ventilation escaping exit aperture；The ventilation pipe for escaping leads directly to road surface or led to after being interconnected
Each described ventilation pipe for escaping is connected with ventilation escape house steward, the outlet of pipeline is reduced with this, it is ensured that road surface
It is preferred that, the ventilation pipe for escaping and ventilation escape house steward are corrugated steel tube.
Staircase is set in ventilation escape tube and ventilation escape house steward.
Operation principle of the present utility model：On the basis of multichannel underground pipe gallery main structure, whole piping lane corridor body
At a certain distance, the position of ventilation escaping exit need to be opened up in the unit pipeline section of respective channel, reserved satisfaction ventilation or personnel enter
The aperture gone out, and pre-embedded bolt or shaped steel flange in the armored concrete of aperture.Ventilation pipe for escaping is preferred to use corrugated steel
Tubular construction, and being connected using the flange of corrugated steel tube itself with connection member, between each pipe for escaping of divulging information by two siphunculus,
Three-way pipe or swan neck realize vertical and horizontal connection.When piping lane occur sedimentation etc. it is dangerous when, the personnel of each passage flee to
Nearest ventilation escaping exit, into ventilation pipe for escaping, is fled to road surface, the ventilation with ripple struction by staircase in pipeline
Pipe for escaping, the absorbable vertical and lateral deformation of its vertical ripple, the deformation of the absorbable radial direction of transverse wave and axial direction is effectively anti-
Only cracking and leak.
Beneficial effect：Compared with prior art, the utility model has advantages below：First, by each ventilation pipe for escaping
It is interconnected, individually leads to road surface compared to ventilation pipe for escaping, saved cost, and ensure that the attractive in appearance of road surface；Secondly, this leads to
Wind pipe for escaping uses precast assembly form, and construction speed is secure；Again and, using corrugated steel tube, can absorb vertical and lateral
Deformation, the deformation of the absorbable radial direction of transverse wave steel pipe and axial direction, effectively prevents cracking and leak.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model ventilation pipe for escaping structure one；
Fig. 2 is the schematic diagram of the utility model ventilation pipe for escaping structure two.
The technical solution of the utility model is described further with reference to the accompanying drawings and examples.
As shown in figure 1, the multichannel underground pipe gallery with ventilation escape mouth structure, its piping lane main body 1 is with four
The armored concrete corridor body of channel design, the ventilation for connecting ventilation pipe for escaping 2 is opened up at the top of each passage 101 and is escaped
Raw mouth 3, its port size meets ventilation or personnel's turnover is required, bolt 401, the ventilation are buried in each aperture armored concrete
Pipe for escaping is corrugated steel tube, is connected by the flange 201 of itself with bolt 401；Bolt can also be replaced using shaped steel flange
401, shaped steel flange can not only play connection function, also act as the reinforcement effect to connector；Further, it is also possible in ventilation escape
Between pipeline 2 and bolt 401, add U-shaped tubular shaped steel flange 5, thereon lower flange side respectively with ventilation pipe for escaping 2 bottom
The flange 201 and the bolt 401 in aperture carried is connected.The ventilation pipe for escaping 2 of each passage 101 can lead directly to road surface, but meeting
Cause the problem of pipe outlet is more, in order to ensure that road surface is attractive in appearance and reduce construction cost, each ventilation in present embodiment is escaped
Raw pipe 2 forms ventilation escape house steward 10 and leads to road surface both sides, ventilation escape house steward 10 includes by connecting pipe cross connection
Four Steel triplet pipes 6, two steel elbows 7 and two steel bipasses 8；It is preferred that, ventilation escape total pipeline 10 and ventilation
Escape tube 2 uses corrugated steel tube, and each connecting pipe is realized successive by the flange of pipe end.Pass in and out for convenience, in pipe
The staircase 9 climbed for personnel is additionally provided with road.
Another embodiment of the present utility model is illustrated in figure 2, wherein, first passage 2-1 ventilation pipe for escaping 2
Road surface side, second channel 2-2, third channel 2-3 and are led directly to by two steel elbows and a steel bipass
Four-way 2-4 is by steel bipass, Steel triplet pipe and steel elbow cross connection, then passes through a steel elbow and one
Steel bipass leads to road surface opposite side.
