Research on BIM Intelligent Temperature Control System and Method for Mass Concrete
Research purposes:For the problem that the mass concrete of the ultra-high main tower is prone to crack due to the excessive temperature of the concrete in the construction process,BIM intelligent temperature control system and the method are studied,the REVIT software is selected for modeling and secondary integrated development with big data platform,and the intelligent temperature control system is established by using 4G wireless network communications equipment,industrial integration server and computer software.Moreover,it is equipped with artificial intelligence control algorithm to make advance prediction and intelligent decision of the whole process temperature of mass concrete.Research conclusions:(1)The temperature monitoring subsystem of mass concrete raw materials and outgoing machine,and the temperature monitoring subsystem of concrete mold entering and hardening process are established,which can dynamically monitor the temperature of the whole process of concrete construction through 4G wireless transmission and reception of temperature measuring element data.(2)The position of temperature measurement points is marked in the BIM model and the temperature change is visually reflected synchronously,and the overrun warning is carried out.(3)Advance prediction and intelligent decision are made on the temperature of outgoing machine,entering mold and hardening process of mass concrete,and a series of decision methods are provided such as raw material temperature control and water-cooling system control to ensure that the temperature of construction process meets the specification requirements.(4)The control system and method have been applied in the mass concrete temperature control of the ultra-high main tower of the Yangtze River Bridge with highway and railway in Ma'anshan,and achieved good application results.
