Specific embodiment

In order to which the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with attached drawing and reality Example is applied, the present invention will be further described in detail.It should be understood that specific embodiment described herein is only used for It explains the utility model, is not used to limit the utility model.

Embodiment one:

As shown in Figure 1, the concrete curing equipment in the present embodiment includes: moisturizing layer 1, it is covered in 2 surface of concrete； Air bag component is used to hinder after being filled with gas that heat exchange to occur between the concrete 2 and surrounding air.

Specifically, as shown in Fig. 2, the moisturizing layer 1 includes self-adhering type adhered layer 11 ', the absorbing membrane 11, nothing being sequentially overlapped Woven fabric 12 and plastic foil 13, wherein the adhered layer 11 ' is bonded with 2 surface of concrete, and the adhered layer 11 ' for Hydrone passes through；Preferably, one layer of water-absorption particle 14, the water suction are additionally provided between the non-woven fabrics 12 and plastic foil 13 Film 11 and/or water-absorption particle 14 are that polymer absorbent material is made, and it can be polychlorostyrene that the plastic foil 13, which is impermeable layer structure, One or more of ethylene, polyethylene, polypropylene, polystyrene are made.

The moisture film 1 is nontoxic self-adhering type moisture film, absorbing membrane 11 made of polymer absorbent material and/or The moisture of absorbable 200 times of the self weight of water-absorption particle 14, and liquid water is become solid water, then by the effect of capillary to mixed Solidifying soil surface penetration, while the evaporation water that concrete generates during the heat of hydration is constantly absorbed, keep concrete surface wet, In addition, outermost fluid-tight plastic foil page 13 further prevents the moisture loss of concrete surface, the guarantor in the present embodiment Wet film 1 may make concrete surface to keep moisture state in 28 days, and can effectively reduce concrete surface generation drying shrinkage and split Seam.

Further, such as Fig. 1, shown in 3a-3b, the air bag component includes: frame 31, wherein the frame 31 Generally air-locked closed structure comprising: first support 311 and intersect and be connected to the first support 311 Two brackets 312；The first support 311 and second support 312 are by flexible gas impermeable material (such as rubber, gas-impermeable plastics) It is made, and the internal second gas for being filled with high pressure (1.2-2.0 times of atmospheric pressure)；It is covered on interior on the frame 31 Film 33 and outer membrane 32, the inner membrance 33 and outer membrane 32 are arranged substantially in parallel, and the two is that heat-barrier material is made (such as rubber), and Enclosed construction S closed, that first gas can be filled with is constituted, and the frame 31 is integrally located in the enclosed construction S；And At least one is used for the charger 34 (such as air blower) inflated into the enclosed construction S.

Wherein, the first gas pressure is less than second gas pressure, is filled with the first support 311 of high pressure second gas Thus have certain rigidity with second support 312, can be used for supporting the overall weight of the inner membrance 33 and outer membrane 32；In addition, Convenient for the fixation air bag component, to make it play more uniform heat insulation, 32 surface of outer membrane passes through hook 35 and/or double faced adhesive tape connect with the moisturizing layer 1.

After being passed through gas into the enclosed construction S, between concrete 2, insulating layer 1 and air be inflated air bag component every From thus hindering that heat exchange occurs between the concrete 2 and surrounding air, play heat insulation and preservation effect to concrete 2, subtract The thermal loss of few concrete 2, meanwhile, because enclosed construction S, which is used, is completely closed gastight design, only pacifying It is inflated when dress starts to enclosed construction S, it is not reinflated later, to avoid making because inflating repeatedly into enclosed construction S The case where flowing at air, thus generating heat convection and cause heat loss generation, further enhances heat insulation effect；Lead to simultaneously Cross 1 moisturizing of moisturizing layer so that concrete 1 keeps certain water content for a long time, thus avoid it from scattering and disappearing since moisture is too fast and It causes surface temperature of concrete to change greatly, and avoids resulting desciccation crack or contraction fissure；In addition, frame 31 First support 311 and second support 312 are made of flexible gas impermeable material (such as rubber, gas-impermeable plastics), energy after inflation Shape after effectively maintaining enclosed construction S inflation, meanwhile, for the frame that pvc pipe etc. is built, weight is lighter, When not in use, it is only necessary to which folding storage can be carried out by releasing the gas in first support 311 and second support 312, storage Space is small.

Embodiment two:

As shown in figure 4, present embodiments providing a kind of tunnel concrete maintenance of equipment comprising described in embodiment one Concrete curing equipment, wherein the moisturizing layer 1 is covered in the inner surface of Tunnel Second Lining concrete 100, the inflation Air bag component is arranged in the tunnel, and heat friendship occurs between the secondary lining concrete 100 and tunnel air for hindering It changes.

Preferably, after enclosed construction S inflation with a thickness of 30-100cm (preferably 50cm), length and the tunnel The length of secondary lining concrete one-time-concreting is consistent, and after inflation, the contour line and Tunnel Second Lining of the outer membrane 32 The profile of 100 inner surface of concrete is unanimous on the whole, thus may make the air bag component shape and secondary lining concrete 100 are more bonded, and can more uniformly, comprehensively be kept the temperature to secondary lining concrete 100, moisturizing.

Embodiment three:

It is mixed to present embodiments provide a kind of tunnel realized using the maintenance of equipment of tunnel concrete described in embodiment two Solidifying soil maintenance process comprising following steps:

After the completion of S1, Tunnel Second Lining concreting, pasted in the inner surface of the Tunnel Second Lining concrete Moisture film；

S2, the frame is set up in the tunnel, and cover the inner membrance and outer membrane on said frame；It is close to constitute Enclosed construction close, that gas can be filled with；

It is filled in the first support and/or second support of S3, Xiang Suoshu frame after second gas again to the enclosed construction Inside it is filled with first gas.

In conclusion the utility model prevents concrete from drying shrinkage occurs because of water loss using moisture film, Yi Jitong Gas overcharging air bag component is isolated concrete and air, hinders the generation of heat exchange between the two, thus reduces the temperature of concrete Difference, the drying shrinkage for preventing concrete surface from generating because temperature change is larger or contraction fissure, maintenance of equipment and maintenance process At low cost, good heat insulating is easy to operate.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
