Mass concrete water-cooling temperature control method and equipment
The invention provides a mass concrete water-cooling temperature control method. The mass concrete water-cooling temperature control method comprises the steps that A, a cooling water pipe and a temperature detector are pre-arranged; B, concrete is poured; C, cooling water is refrigerated to ensure that the temperature of the cooling water is lower than the local environment temperature, the cooling water is introduced into the cooling water pipe while the concrete is poured, and the introduction of the cooling water is stopped after a period of time; D, the internal and surface temperatures of the concrete are detected, when the internal temperature of the concrete is higher than the surface temperature and the temperature difference reaches a first set value, the temperature of the cooling water is adjusted to be lower than the internal temperature of the concrete by a second set value and the cooling water is introduced into the cooling water pipe, and the introduction of the cooling water is stopped when the internal and external temperature difference of the concrete is reduced to a third set value; and E, the step D is repeated. The invention further provides temperature control equipment. The process of gradually reducing the internal and external temperature difference is added, so that the internal and external temperature difference is prevented from being rapidly increased due to rapid increase of the internal temperature of the concrete, and the stress caused by the temperature difference is favorably controlled.
本发明提供了大体积混凝土水冷温控方法，包括A、预设冷却水管和温度检测计；B、浇筑混凝土；C、对冷却水进行制冷，使冷却水的温度低于当地环境温度，浇筑混凝土的同时将冷却水通入冷却水管，持续一段时间后停止通入冷却水；D、检测混凝土内部和表面的温度，当混凝土内部温度高于表面温度且温差达到第一设定值时，调节冷却水的温度，使冷却水的温度比混凝土的内部温度低第二设定值，并将冷却水通入冷却水管，当混凝土内外温差降低至第三设定值时停止通入冷却水；E、重复步骤D。还提供了温控设备。由于本发明增加了内外温差逐渐减小这个过程，防止了混凝土内部温度快速增加而导致内外温差快速增大，从而有利于控制温差带来的应力。
