Combined bridge tower mass concrete temperature control method based on ventilation
The invention discloses a combined bridge tower mass concrete temperature control method based on ventilation, which fully utilizes the structural characteristics of a bridge tower, and is characterized in that a plurality of heat exchange chambers are arranged based on a steel box-steel pipe confined concrete combined structure and surround the periphery of a to-be-poured concrete steel pipe to form a heat exchange circulation path; the height range of heat exchange is freely adjusted by opening and closing communicating holes in all positions, a heat preservation section or a cooling section is formed on the steel box, outdoor air is used as a heat exchange source for cooling, and the temperature state of the heat exchange source entering a heat exchange circulation path is adjusted and controlled through an arranged evaporation cooling device. The circulation rate of air on a heat exchange circulation path is regulated and controlled through an air inlet fan, an air outlet fan and a negative pressure fan, so that the range of the temperature in the tower can be flexibly regulated and controlled, the temperature balance can be ensured, the whole regulation and control method is few in equipment added on site, does not affect site construction, is environment-friendly and low in energy consumption, greatly reduces resource investment, and is suitable for industrial production. The economic cost is low.
本发明公开了一种基于通风的组合桥塔大体积混凝土温控方法，充分利用桥塔的结构特点，基于钢箱—钢管约束混凝土组合结构设置多个换热腔室，合围在待浇筑混凝土钢管的外周，形成换热循环路径，通过开关各个位置的连通孔自由调整换热的高度范围，在钢箱上形成保温段或降温段，利用室外空气作为降温的换热源，通过设置的蒸发降温装置调控换热源进入换热循环路径的温度状态，通过设置的进风风机、出风风机、负压风机调控换热循环路径上空气的流通速率，既使得塔内温度的高低范围可灵活调控，又能保证温度的均衡性，整个调控方法在现场增加的设备少，不影响现场施工，环保且能耗低，大大降低了资源投入，经济成本低。
