Concrete heat preservation device

Abstract

The invention relates to a concrete heat preservation device, a first water storage space is formed in a heat preservation assembly, the heat preservation assembly is used for surrounding the periphery of a concrete structure, and the height of the heat preservation assembly is larger than that of the concrete structure, so that a second water storage space communicating with the first water storage space is formed in the top of the concrete structure; one end of the cooling water pipe communicates with the first water storage space of the heat preservation assembly and is used for being arranged in the concrete structure. A water inlet of a pump body is communicated with the second water storage space through a pipeline, and a water outlet is communicated with the other end of the cooling water pipe through a pipeline to form a cold-heat exchange circulation loop. Heated water in the cooling water pipe is collected through the first water storage space and the second water storage space, so that a heat preservation maintenance layer is formed on the top and the side face of the concrete structure, and the cooled water in the second water storage space is fed into the cooling water pipe again through the pump body, so that the effect of inner cooling and outer protection is achieved; and the use of thermal insulation materials and watering maintenance are reduced.

Description

Technical field [0001] The present application relates to the field of concrete construction, and more particularly to a concrete heat preservation device. Background technique [0002] At present, large-volume concrete technology will be used in large-scale construction construction in bridges and dams. For example, in the construction of bridge, the anchor and jacket concrete casts will reach several thousand or even tens of thousands of cubic meters, which belongs to large volume concrete, concrete interior Because the hydration reaction produces a large amount of heat, the internal temperature will be high, and the surface of the concrete surface is low in the environment. At this time, the difference between the internal and surface temperature gaps at this time will result in temperature stress, and even cracks when severe. Therefore, it is especially important to control the internal temperature difference between the concrete. [0003] In some related art, by providing a ...
