Specific embodiment
The invention will be further described with embodiment for explanation below in conjunction with the accompanying drawings, and the mode of the present invention includes but not only limits
In following examples.
Embodiment
As Figure 1-4, a kind of tunnel in cold area anti-freezing and heat-insulating and the integrated facility of fire prevention, including being followed successively by tunnel from outside to inside
Lining 1, tunnel waterproofing layer 2 and tunnel double-lining 3 and fireproof heat insulating one layer 4 at the beginning of road.Described fireproof heat insulating one layer 4 is by factory
Predefined region lattice 5 fixation of processing is assembled, and predefined region lattice 5 are enclosed seal gas cavity 7 dislocation setting and are made by PLASTIC LAMINATED,
It is thusly-formed PLASTIC LAMINATED and airtight air chamber replaces body, realizing also may be used while tunnel in cold area heat-insulation layer is integrated with fireprotection layer
Fire protecting performance and the heat-insulating property in tunnel are greatly improved；It is provided with more than one in described seal gas cavity 7 and adopt PLASTIC LAMINATED system
The demarcation strip 6 made, described demarcation strip 6 is used for increasing rigidity and the intensity of predefined region lattice 5, simultaneously will be empty in seal gas cavity 7
Edema caused by disorder of QI chamber separates, and the local that can be prevented effectively from fireproof heated board is punctured thus forming cross-ventilation heat exchange to further result in guarantor
The situation that warm nature can reduce occurs.Described seal gas cavity 7 adopts dislocation form, its purpose is to ensure predefined region lattice 5
The insulation of seam portion of the assembled fireproof heat insulating one layer 4 being formed is identical with predefined region lattice 5 with fire protecting performance.
Described tunnel double-lining 3 inner surface is provided with mounting hook 10, the described seal gas chamber positioned at predefined region lattice 5 outside
The lateral surface of body 7 is provided with the draw-in groove 11 matching with mounting hook 10, and described fireproof heat insulating one layer 4 passes through mounting hook 10
It is laid in the way of hanging tag on tunnel double-lining 3 inner surface with draw-in groove 11, so can achieve that the scene of fireproof heat insulating one layer 4 is fast
Speed installs laying.The optimal making material of the predefined region lattice 5 of anti-freezing and heat-insulating and fire prevention one layer 4 can be selected for the property such as glass magnesium fireproof board
The excellent fire-proof board of energy.
Described seal gas cavity 7 is provided with tenon structure, and described fireproof heat insulating one layer 4 is passed through convex by predefined region lattice 5
Tenon structure wedging is spliced.Described tenon structure includes tenon 8 and the mortise 9 matching with tenon 8, described positioned at predefined region
Tenon 8 on the seal gas cavity 7 in lattice 5 outside and mortise 9 are respectively arranged on the two ends of seal gas cavity 7, described positioned at pre-
Tenon 8 on the seal gas cavity 7 of area processed lattice 5 inner side and mortise 9 are respectively arranged on top and the bottom of seal gas cavity 7.
Spliced using tenon structure, further increase the scene laying efficiency of fireproof heat insulating one layer 4, decrease screw simultaneously
Deng the use of parts, also will not bring because of the shortage of the parts such as screw often occurring in construction while cost-effective
The situation such as the duration is slow.In order that the antifreezing heat insulation of fireproof heat insulating one layer 4 is better, enter in fireproof heat insulating one layer 4
During row splicing, the airtight adhesive glue with microdilatancy performance, environment-protecting asepsis can be smeared on tenon structure, spell for blocking area's lattice
Faint air flow that may be present between dress seam.
For solving the problems, such as pole cold district or country rock has the freezing damage in tunnel in frost heave area, present invention additionally comprises heating system
System, described heating system includes the temperature sensor 12 being laid on tunnel double-lining 3 inner surface, is equidistantly provided at predefined region lattice
5 outside the lateral surface of seal gas cavity 7 on heater 13, and simultaneously with temperature sensor 12 and heater 13
The controller 14 connecting, described controller 14 is located on tunnel double-lining 3 inner surface or is located at the sealing sky in predefined region lattice 5 outside
On the lateral surface of air cavity 7.The temperature of temperature sensor 12 real-time monitoring tunnel double-lining 3 wall, and it is sent to controller in real time
14, when controller 14 receive temperature sensor 12 monitor tunnel double-lining 3 wall temperature be less than 0 DEG C when, control start plus
Thermal 13 provides heat for tunnel, and preventing and treating freezing damage in tunnel occurs, thus realizing the active anti-freezing and heat-insulating of tunnel in cold area.
The fireproof heat insulating one layer 4 of present invention design is it is achieved that tunnel in cold area heat-insulation layer is integrated with fireprotection layer, and leads to
Cross multilamellar PLASTIC LAMINATED and replace with seal gas chamber and fire protecting performance and heat-insulating property are greatly improved.Paving by assembled insulated fire plate
If mode, it is to avoid traditional tunnel in cold area layering laying heat-insulation layer and fireprotection layer and the step installing Os Draconis, simplify construction work
Sequence, reduces construction cost.Meanwhile, the form of precast assembly is conducive to the Guan Yangyu that the phase is runed in tunnel to change, and improves pipe and supports
Efficiency, reduces pipe and forms this.It is suitable to 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 the protection model of the present invention
Enclose, as long as in the body design thought of the present invention and change or the polishing of having no essential meaning mentally made, it is solved
Technical problem still consistent with the present invention, all should be included within protection scope of the present invention.
