Bridge substructure concrete hydration heat release device
The invention discloses a concrete hydration heat release device for a bridge substructure, and relates to the technical field of heat dissipation of mass concrete structures. Comprising a water cooling system, a temperature detection system and a master controller. The water cooling system comprises a plurality of cooling water pipes and a water suction pump which are arranged in the bridge lower structure; the temperature detection system comprises temperature detection modules which correspond to the cooling water pipes in number and are used for detecting the temperature of the positions of the corresponding cooling water pipes. The master controller controls opening and closing of the water cooling system to absorb hydration heat according to the temperature signal. According to the invention, the master controller is accurately positioned to the region with high local temperature in the bridge substructure according to the electric signal, and controls the cooling water pipes at the corresponding positions to work to absorb hydration heat to accelerate heat release, so that the overall heat release effect of the bridge substructure is ensured, the local heat release effect in the bridge substructure is also considered, and the service life of the bridge substructure is prolonged. And the phenomenon that the bridge substructure cracks due to hydration heat of cement is effectively avoided.
本申请公开了一种桥梁下部结构混凝土水化热释放装置，涉及大体积混凝土结构散热的技术领域。包括水冷系统、温度检测系统和总控制器；水冷系统包括多个布设于桥梁下部结构内的冷却水管和抽水泵；温度检测系统包括与冷却水管数量对应设置的用于检测对应冷却水管位置处温度的温度检测模块；总控制器根据温度信号控制水冷系统的开闭吸收水化热量。本申请中总控制器根据电信号精确定位到桥梁下部结构内局部温度较高区域，并控制对应位置处的冷却水管工作吸收水化热加快热量释放，既保证了桥梁下部结构的整体热量释放效果，又兼顾了桥梁下部结构内的局部热量释放效果，有效避免了桥梁下部结构因水泥水化热而发生的开裂现象。
