Warm-keeping device for winter construction of mixing station and construction method

Abstract

The invention discloses a mixing station winter construction heat preservation device and a construction method, the mixing station winter construction heat preservation device comprises a hot water pipe, a heat conduction steel plate, a heating radiator, an external air source heat pump unit and a mixing station stock bin, during construction, a foundation pit is dug, a reserved groove for placing the heat conduction steel plate is reserved, a strip-shaped foundation is constructed in the middle, and a channel steel support is installed in the foundation pit; a heating radiator is fixed on a channel steel support and communicated with an external air source heat pump system through a bottom hot water pipe, and after the bottom heating radiator and the hot water pipe are installed and the strip-shaped foundation is maintained, a heat conduction steel plate is placed on a reserved groove and the strip-shaped foundation to ensure stable placement and communicated with an external heat source. And the whole warm-keeping measure is completed. According to the invention, heat cycle of air energy and water is utilized, and local solar energy resources are fully utilized, so that the sand-gravel materials in the stock bin of the mixing station in winter are heated and insulated, and the concrete construction quality in winter can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a heating device and a construction method for winter construction of a mixing station. Background technique [0002] In recent years, with the change of the environment, the winter in some areas is early, the temperature is low, the temperature of the water is also low, the space in the silo of the mixing station is large, the traditional coal-fired insulation effect is not good and pollutes the environment, the concrete used in concrete The temperature of the sand and gravel itself is very low, and the heat energy of hydration heat alone cannot be used for normal construction, which has a great impact on the construction of concrete. At low temperature, the activity of concrete is low, and it is difficult to produce a good chemical reaction. For concrete structures, there are great hidden dangers in quality. SUMMARY OF THE INVENTION [0003] The purpose of the ...

[0002] In recent years, with the change of the environment, some areas have entered winter earlier, the temperature is low, the water temperature is also low, the space in the silo of the mixing station is large, the traditional coal-fired insulation effect is not good and pollutes the environment, and the concrete used The temperature of sand and gravel itself is very low, and the heat energy of hydration heat alone cannot be used for normal construction, which has a great impact on concrete construction. At low temperatures, the activity of concrete is low, and it is difficult to produce good chemical reactions. The strength of concrete cannot be increased, and the quality is greatly affected. There is a great quality hidden danger for the concrete structure
