Abstract
The utility model relates to a maintaining and protecting pad of cement concrete road surfaces, characterized in that the maintaining and protecting pad is provided with an upper plastic film layer 3 and a lower plastic film layer 4, and the peripheries of the upper plastic film layer 3 and the lower plastic film layer 4 are connected. The bottom side of the upper plastic film layer is provided with a small air pillar 5 arranged in the enclosed hollow cavity of the maintaining and protecting pad. When the maintaining and protecting pad is covered on the cement concrete road surfaces after being constructed, on one hand, water evaporation of the concrete can be prevented because of the covering of the maintaining and protecting pad, and on the other hand, the maintaining and protecting pad is heated by the solar radiating heat, and the heat is conveyed to the road surfaces. Simultaneously, the air in the inner cavity has the function of heat storage and preservation. The application of the maintaining and protecting pad can shorten the maintaining and protecting period of the road surfaces.
Description
The utility model relates to a kind of cement concrete pavement maintenance pad.
Existing a kind of cement concrete pavement maintenance process is a topped plastic film layers on the road surface, thereby can prevent effectively that moisture from evaporating in concrete.Its shortcoming mainly is not have air blanketing between this film and the road surface, thereby can't effectively utilize solar energy when fine day.
The purpose of this utility model be to provide a kind of cement concrete pavement maintenance pad it can not only prevent water evaporates in the concrete bodies, and can effectively utilize solar energy, strengthen the accumulation of heat and the heat insulation effect on road surface.
The utility model is to constitute like this, and it has the joining upper and lower plastic film layers of periphery, and the bottom side of last plastic film layers is provided with the minute bubbles that are positioned at maintenance pad closed cavity.
Work as fine day, with on the topped cement concrete pavement after construction of the utility model the time, on the one hand because the covering role of maintenance advance capital for body can prevent the water evaporates in the concrete; Because the width of cloth of the sun is penetrated heat effect, maintenance advance capital for body heats up and conducts heat to the road surface on the other hand, and the air of the pad of maintenance simultaneously inner chamber has played the effect of accumulation of heat and insulation again.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is this practical cross-section structure schematic diagram (1 expression road surface among the figure, 2 expressions are pressed in the briquetting on the utility model limit).
With reference to accompanying drawing, embodiment of the present utility model has the joining upper and lower plastic film layers 3,4 of periphery, and the bottom side of last plastic film layers is provided with the stingy post 5 that is positioned at maintenance pad closed cavity 6.
Above-mentioned last plastic film layers is the transparent plastic photic zone, and following plastic film layers is the black plastic heat-sink shell.
Above-mentioned little gas column is cylindrical.
Embodiment of the present utility model in use should be with the transparent plastic photic zone up, and the black plastic heat-sink shell is close to the road surface.When solar radiation, top photic zone translucent effect is good, and middle air blanketing and beneath heat-sink shell absorb heat big.In addition, can observe: by day, solar radiation can flash to the water on road surface self vaporific gas, the rebasing side high humidity of maintenance, and to evening, vaporific gas condensed into the globule after temperature descended, and dropped on the road surface just like water seasoning.Except the heat storing and heat preserving effect of maintenance pad, add the heat of hydration that hydrated cementitious is emitted, cause the curing temperature on road surface to raise, can shorten the curing period on road surface widely from face, reach the purpose that is open to traffic in advance.
The utility model economy, light, result of use is good.Its application prospect is considerable.
