Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a temperature control cooling water pipe device for mass concrete. Background Technique

[0002] During the pouring process of mass concrete, due to the generation of a large amount of hydration heat, the temperature inside the concrete continuously rises and the volume expands. After the pouring of mass concrete is completed, the heat generated by the hydration heat gradually dissipates, and the drastic temperature change is likely to cause concrete cracks. Therefore, temperature control for mass concrete construction is particularly important. The traditional temperature control measure for mass concrete is to use horizontal circulating cooling water pipes, which are horizontally arranged in layers along the height direction according to the calculation results. During construction, the horizontal circulating cooling water pipes are laid while the steel bars of the mass concrete structure are being tied. This layout method has a large number of joints during connection, and each cooling pipe also needs to be provided with a separate water inlet and grouting port. Not only is the installation efficiency low, the grouting and plugging efficiency is low, and the construction difficulty is high. This method is suitable for the construction of mass concrete with regular shapes, large planar dimensions, low heights, and simple steel bar and prestress layouts. It is not very suitable for the construction of mass concrete with irregular shapes, relatively large heights compared to planar dimensions, complex steel bar and prestress layouts, and local temperature control requirements. At the same time, when the circulating cooling pipes are cooling, the generated waste water is not reasonably utilized, resulting in serious resource waste.

At the same time, after heat exchange, the filtered water flow is transported into the cooling water tank 16 for recycling. Through the above design, not only can the heat energy of the cooling wastewater be recovered and utilized, but also it can be recycled as cooling water, effectively avoiding waste of resources.
