Mass concrete cooling construction method
The invention discloses a cooling construction method for mass concrete. A phase change ventilation pipeline is pre-buried before concrete pouring construction; concrete is poured, and temperature detection points are arranged in the concrete; gas and/or liquid in the phase change ventilation pipeline circularly flows by connecting an air pump and a ventilation pipe outside the concrete; closing the air pump when the internal and external temperatures of the concrete are consistent and reach normal temperature; the phase change ventilation pipeline is filled with cement paste; the phase-change pipeline contains the phase-change material, phase change occurs at 40-60 DEG C, and concrete hydration heat is absorbed; gas and/or liquid (phase change components) in the phase change ventilation pipeline circularly flow through an externally connected air pump, heat of a high-temperature part of concrete is absorbed and transferred to concrete at a low-temperature part, and the temperature difference between the inside and the outside of the concrete is reduced; water is not needed, and the problems that traditional construction is low in speed, and resources are wasted are effectively solved; operation is easy and convenient, resource consumption is reduced, construction quality is improved, and construction cost is reduced.
本发明公开了一种大体积混凝土的降温施工方法，在混凝土浇筑施工之前预埋相变通气管道；浇筑混凝土并在内部布置温度检测点；通过连接混凝土外部的气泵和通气管，使相变通气管道内的气体和/或液体循环流动；混凝土内外部温度一致并达到常温时关闭气泵；用水泥浆对相变通气管道进行填充；本发明相变管道中含有相变材料，在40‑60摄氏度发生相变，吸收混凝土水化热量；通过外部连接气泵使相变通气管道中气体和/或液体(相变成分)循环流动，吸取混凝土高温部分的热量传给低温部位的混凝土，减少混凝土内外温差；不需要用水，有效地解决传统施工速度慢资源浪费等问题；不仅操作简便，降低资源消耗，而且提高施工质量，降低施工成本。
