Specific embodiment
The invention will be further described with embodiment for explanation with reference to the accompanying drawing, and mode of the invention includes but not only limits
In following embodiment.
Embodiment
As shown in Figs 1-4, a kind of tunnel in cold area anti-freezing and heat-insulating and integrated facility of preventing fires, including it is followed successively by tunnel from outside to inside
Road just serves as a contrast 1, tunnel waterproofing layer 2 and tunnel double-lining 3 and fireproof heat insulating one layer 4.The fireproof heat insulating one layer 4 is by factory
The fixation of predefined region lattice 5 of processing is assembled, and predefined region lattice 5 are enclosed the dislocation of seal gas cavity 7 set by fire-proof plate and are made,
It is thusly-formed fire-proof plate and closed air chamber alternating body, is realizing tunnel in cold area insulating layer and fireprotection layer is integrated may be used also simultaneously
Greatly improve the fire protecting performance and thermal insulation property in tunnel;More than one, which is equipped with, in the seal gas cavity 7 uses fire-proof plate system
The demarcation plate 6 of work, the demarcation plate 6 are used to increase the stiffness and strength of predefined region lattice 5, while will be empty in seal gas cavity 7
The partition of gas sub-chamber can avoid the part of fireproof heated board from being punctured effectively to form cross-ventilation heat exchange and further result in guarantor
The situation of warm reduced performance occurs.The seal gas cavity 7 uses dislocation form, and its purpose is to guarantee predefined region lattice 5
The heat preservation of the seam portion for the fireproof heat insulating one layer 4 that assembly is formed and fire protecting performance are identical as predefined region lattice 5.
3 inner surface of tunnel double-lining is equipped with installation hook 10, the seal gas chamber positioned at 5 outside of predefined region lattice
The lateral surface of body 7 is equipped with the card slot 11 to match with installation hook 10, and the fireproof heat insulating one layer 4 passes through installation hook 10
It is laid in a manner of hanging tag on 3 inner surface of tunnel double-lining with card slot 11, the scene of so achievable fireproof heat insulating one layer 4 is fast
Speed installation is laid with.The property such as glass magnesium fireproof board can be selected in the best making material of the predefined region lattice 5 of anti-freezing and heat-insulating and integrated layer 4 of preventing fires
The excellent fire-proof board of energy.
The seal gas cavity 7 is equipped with tenon structure, and the fireproof heat insulating one layer 4 is passed through convex by predefined region lattice 5
Tenon structure wedging is spliced.The tenon structure includes tenon 8 and the mortise to match with tenon 89, described to be located at predefined region
Tenon 8 and mortise 9 on the seal gas cavity 7 in 5 outside of lattice are respectively arranged on the both ends of seal gas cavity 7, described to be located in advance
Tenon 8 and mortise 9 on the seal gas cavity 7 of lattice 5 inside in area's processed are respectively arranged on the top and bottom of seal gas cavity 7.
Spliced using tenon structure, the scene for further improving fireproof heat insulating one layer 4 is laid with efficiency, while reducing screw
The use of equal components, save the cost while, will not also bring because often there is the shortage of the components such as screw in construction
The situations such as the duration is slow.In order to make the antifreezing heat insulation better effect of fireproof heat insulating one layer 4, fireproof heat insulating one layer 4 into
When row splicing, can smear in tenon structure has micro-expansibility energy, environment-protecting and non-poisonous airtight adhesive glue, for blocking area's lattice to spell
Faint air flowing that may be present between dress seam.
To solve the problems, such as that pole cold district or country rock have the freezing damage in tunnel in frost heave area, the invention also includes heating to be
System, the heating system includes the temperature sensor 12 being laid on 3 inner surface of tunnel double-lining, is equidistantly provided at predefined region lattice
5 outside seal gas cavity 7 lateral surface on heating device 13, and simultaneously with temperature sensor 12 and heating device 13
The controller 14 of connection, the sealing that the controller 14 is located on 3 inner surface of tunnel double-lining or positioned at 5 outside of predefined region lattice are empty
On the lateral surface of air cavity 7.The temperature of 12 real-time monitoring tunnel double-lining of temperature sensor, 3 wall surface, and real-time transmission is to controller
14, when controller 14, which receives temperature sensor 12, monitors the temperature of 3 wall surface of tunnel double-lining less than 0 DEG C, control starting adds
Thermal 13 provides heat for tunnel, prevents and treats freezing damage in tunnel, to realize the active anti-freezing and heat-insulating of tunnel in cold area.
The fireproof heat insulating one layer 4 that the present invention designs, it is integrated with fireprotection layer to realize tunnel in cold area insulating layer, and lead to
It crosses multilayer fire-proof plate and replaces with seal gas chamber and greatly improve fire protecting performance and thermal insulation property.Pass through the paving of assembled insulated fire plate
If mode, the step of traditional tunnel in cold area layering is laid with insulating layer and fireprotection layer and installation keel is avoided, construction work is simplified
Sequence reduces construction cost.Meanwhile the form of precast assembly is conducive to the Guan Yangyu replacement of tunnel operation phase, improves pipe and supports
Efficiency reduces pipe and forms this.Suitable for wide popularization and application in extremely frigid zones constructing tunnel.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit protection model of the invention
It encloses, as long as that in body design thought of the invention and mentally makes has no the change of essential meaning or polishing, is solved
The technical issues of it is still consistent with the present invention, should all be included within protection scope of the present invention.
