Tensioning water circulation heating system for retard-bonded prestressed tendons under low-temperature condition

The invention discloses a retard-bonded prestressed tendon tensioning water circulation heating system under a low-temperature condition, which comprises the following steps: S1, customizing a hydrothermal heat radiation film system, and determining the size of the hydrothermal heat radiation film system according to the size of an on-site prestressed concrete structure; s2, the hydrothermal heat radiation film systems are laid and fixed, the hydrothermal heat radiation film systems can be freely combined and used according to the areas and the lengths of the components, the prestressed concrete structural beams can be completely covered with the horizontal components during laying construction, after laying is completed, the horizontal components are bonded into sheets through bonding devices on the horizontal components, and a hydrothermal heat radiation film system group is formed; and laying construction of the vertical component is carried out. According to the method, the influence ...
