Automatic temperature control method for mass concrete
The invention discloses a mass concrete automatic temperature control method which comprises the following steps: S1, before mass concrete is poured, a cooling water pipe and a plurality of temperature measuring ropes are pre-buried in the mass concrete, and meanwhile, a water tank in which a large amount of water is stored is arranged outside the mass concrete; s2, collecting the following multiple groups of stable data through a temperature measuring rope; s4, before the mass concrete is poured, the flow speed of water flow in the cooling water pipe is 0; s5, the internal temperature is gradually increased, the three kinds of temperature data are collected once every five seconds through a temperature measuring rope within 7 days after pouring, the data are transmitted to a PLC control cabinet, the PLC control cabinet calculates the flow speed v of the cooling water pipe according to the function relation, the flow speed of water in the water pipe is controlled in real time by controlling the rotating speed of a water pump, and the flow speed of the water in the water pipe is controlled in real time. Therefore, the temperature of the cooling water pipe located in the mass concrete is adjusted. Warm water is adopted for cooling, and the temperature gradient around the cooling water pipe is reduced.
本发明公开了一种大体积混凝土自动控温方法，所述控温方法包括如下步骤：S1：在大体积混凝土浇筑前，在其内部预埋冷却水管和若干测温绳，同时在外部设置有内部存储大量水的水箱；S2：通过测温绳对下列多组稳定数据进行采集；S4：大体积混凝土浇筑前，冷却水管内部水流的流速为0；S5：其内部温度开始逐渐升高，从浇筑起至其后的7天内，通过测温绳每5秒采集一次上述所述的三类温度数据，并将数据通过传输给PLC控制柜，PLC控制柜根据上述函数关系计算冷却水管流速v，并通过控制水泵转速，从而实时控制水管内水的流速，从而对位于大体积混凝土内部的冷却水管的温度进行调节。本发明采用温水降温，减小冷却水管周围温度梯度。
