泵送大体积混凝土通水冷却远程调控设计与应用
Design and application of remote control for water-cooling in pumped mass concrete
摘要
Abstract
Pumped mass concrete is characterized by high hydration-heat temperature rise and rapid temperature increase.Direct cooling with low-temperature water can easily result in an excessive temperature difference between the cooling water and the internal temperature of the pouring block.Manual water temperature regulation,moreover,is labor-intensive and inefficient.To address these issues,this paper developed a remote control regulation system for pipe cooling of pumping concrete.The system integrated a wireless temperature acquisition device,a water exchange device,and an electronic control device unit with a self-circulating water tank.A preset allowable temperature difference between the maximum internal temperature of the pouring block and the inlet water temperature served as the constraint.Cold water from well was used to displace a certain volume of hot water in the water tank,thereby achieving a suitable water temperature.This process ensured the temperature difference between the concrete and the cooling water complies with the standard,optimizing the cooling effect.A successful application in the ongoing Shengjin Lake Pump Station project demonstrated the system's effectiveness.With the allowable temperature difference set at 20℃,multiple rounds of remote adjustment were performed.As the temperature of the pouring block gradually increased,the inlet water temperature was dynamically adjusted within a range of 19.0℃ to 54.5℃.The temperature difference between the concrete and the inlet water was effectively controlled within 19.9 ℃.This practice confirmed that the system proficiently regulates the cooling water temperature,thereby enhancing the intelligence of temperature control for mass pumped concrete.关键词
