摘　　要：为加快新浇筑混凝土的硬化及强度的增长,需对混凝土进行洒水养护,使混凝土在适宜的湿度及温度条件下持续发生水化反应并实现混凝土强度的持续增长。目前我国传统的养护方法是依据经验,在任意时间段对混凝土构件进行人工洒水养护,然而这种养护方式由于养护不及时或水分蒸发过快易使混凝土构件出现开裂等现象,对混凝土强度及结构的安全性产生影响。为解决养护不及时及主观经验性的影响,基于PLC自动化控制及传感器等技术研制了用于混凝土结构养护的智能化养护系统。首先根据混凝土水化热释放规律确定养护系统喷淋间隔时间;其次,结合现场监测温湿度,合理调整自动喷淋间隔时间;最后,通过在施工现场进行实际应用,结果表明该系统能有效提高混凝土构件的养护质量,并降低施工成本。To accelerate the hardening and strength growth of the newly poured concrete,it is necessary to conserve the concrete so that the hydration reaction of the concrete can continue under the appropriate humidity and temperature conditions and realize the continuous growth of the concrete strength.At present,the traditional curing method in our country is to carry on the artificial watering curing of concrete members at any time according to experience.However,this kind of curing method is easy to crack the concrete members because the curing is not timely or the water evaporates too fast,which has an impact on the strength of concrete and the safety of the structure.In order to solve the influence of delayed maintenance and subjective experience,an intelligent maintenance system for concrete structure maintenance was developed based on PLC automatic control and sensor technology.Firstly,spray interval time of curing system is determined according to the law of concrete hydration heat release.Secondly,combined with the on-site monitoring temperature and humidity,reasonable adjustment of automatic spraying interval time.Finally,through the practical application in the construction site,it shows that the system can effectively improve the maintenance quality of concrete components and reduce the construction cost.
