The device for adjusting the temperature difference between the inside and the outside of the concrete is characterized in that a waterproof temperature adjustment type electric blanket (2) is arranged on the inner side of the concrete formwork (1), a cooling water pipe (5) is arranged inside the concrete (4) in an embedded mode, thermometers T1 (6) are arranged at the positions, close to the edges of two sides, of the interior of the concrete (4), and a thermometer T2 (7) is arranged in the middle of the interior of the concrete (4). The device for adjusting the temperature difference between the inside and the outside of the concrete has the advantages of being low in technical risk, simple, easy to implement, convenient to use, practical, low in cost and the like.
Description
Technical field
The utility model relates to a kind of temperature control measures of concrete dam, particularly a kind of device of regulating temperature difference between inside and outside concrete.
Background technology
At present, according to the domestic concrete dam temperature control measures of constructing season in severe winter, wood power station, Tibetan as severe cold area, dam is normal concrete, paste polystyrene thermal insulation plate in the general employing concrete blinding during concrete construction, owing to adopt warming plate to carry out the interior insulation of pasting, concrete and the external world can not be isolated fully, concrete surface causes surface temperature and ambient temperature to be more or less the same constantly to extraneous loses heat energy.In addition, the severe cold season temperature of concrete during construction is just very low, normal concrete cement factor height, heat of hydration energy is big, concrete thermal insulation warming height, when be in sometime section the age of concrete, its internal temperature values and surface temperature value difference value reached maximum and surpass the permission difference range, finally cause dam body external crack or penetrability crack to occur, operation brings very big harm to engineering safety.Therefore above technical measures are difficult to satisfy the concrete temperature requirements of constructing season in severe winter.
Summary of the invention
The purpose of this utility model is to overcoming the deficiency of existing temperature control technology; a kind of device of regulating temperature difference between inside and outside concrete is provided; by concrete surface is carried out to heat; guarantee in the concrete internal temperature uphill process with the surface temperature difference in the allowed band value, thereby avoid dam body external crack or penetrability crack to occur.
For realizing the purpose of this utility model, the utility model has adopted such technical scheme: a kind of device of regulating temperature difference between inside and outside concrete of the present utility model, it comprises concrete and is used for the concrete blinding of this concreting, be provided with water proof type temperature-adjusting type electric blanket at this concrete blinding, be embedded with cooling water pipe at this inside concrete, position near both sides of the edge in this concrete is provided with thermometer T1, and the middle part is provided with thermometer T2 in this concrete.Because internal temperature is big during concreting, and the winter construction surface temperature of concrete reduces soon, make concrete internal temperature too high and outside low excessively, device of the present utility model is by internal cooling and externally heat, thereby makes the concrete inside and outside temperature difference adjusted.
Further, aforesaid water proof type temperature-adjusting type electric blanket is fixed on the aforesaid concrete blinding with flat thin magnet.
Further, aforesaid cooling water pipe layering curved arrangement in described concrete.This layering curved arrangement is bending cycle arrangement in layer, makes each position of inside concrete all obtain uniform decrease in temperature.
Owing to adopted the technical solution of the utility model, before concreting, utilized flat thin magnet that water proof type temperature-adjusting type electric blanket is fixed in the concrete blinding inboard; When concreting, bury cooling water pipe and thermometer underground at inside concrete; After concreting is finished, concrete is carried out the water flowing cooling, and dynamically adjust surface temperature of concrete by water proof type temperature-adjusting type electric blanket, make the reading difference control of thermometer T1 and thermometer T2 in the allowed band value.Owing to having adopted water proof type temperature-adjusting type electric blanket, not only avoid the concrete surface heat radiation and caused surface temperature to reduce, after giving heat to concrete surface, guaranteeing that the inside and outside temperature difference of concrete is in the allowed band value simultaneously.The utility model technical measures technical risk is little, simple, convenient and practical, take full advantage of water proof type temperature-adjusting type electric blanket and be incubated characteristics to heat, not only with low cost, play good effect to avoiding dam body generation external crack or penetrability crack, guarantee the safe operation of engineering, nor can self leave over down permanent defective to hydraulic structure, be worthy to be popularized.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
See Fig. 1 earlier, Fig. 1 has showed section layout of the present utility model, as can be seen from the figure, technical measures of the present utility model mainly are to build when finishing when concrete 4, utilize cooling water pipe 5 to carry out the water flowing cooling, utilize 2 pairs of concrete 4 surface heat preservations of water proof type temperature-adjusting type electric blanket to give heat simultaneously, and dynamically adjust water proof type temperature-adjusting type electric blanket 2 power, guarantee that the reading difference of thermometer T2 7 and thermometer T1 6 is in the allowed band value.
Fig. 2 Fig. 3 has showed the layout of water proof type temperature-adjusting type electric blanket 2, and water proof type temperature-adjusting type electric blanket 2 is affixed on concrete blinding 1 inboard in must be entirely, and is fixed by flat thin magnet 3.
Fig. 4 has showed the structural shape of flat thin magnet 3, and the quantity of flat thin magnet 3 determines that by water proof type temperature-adjusting type electric blanket 2 weight simultaneously, flat thin magnet 3 is evenly arranged in water proof type temperature-adjusting type electric blanket 2 surfaces, guarantees its surfacing.
Certainly, more than be concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the desired protection domain of the utility model.
