Research on Intelligent Concrete Spray Curing System and Engineering Application
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.
