Abstract: Pipe cooling is one of the most commonly used temperature control measures during the construction period of mass concrete. Manual operation is labor-intensive and costly. According to the characteristics of temperature control for the ship lock structure concrete,based on the related specifications and the experience of intelligent control of water cooling for the underground hydraulic lining concrete,three intelligent control parameters of water cooling（time for water cooling,water temperature and temperature falling velocity）for structural concrete are determined. Furthermore,the control objectives of internal temperature curve and technical methods for intelligent control are proposed. According to the research findings,intelligent control device is developed and applied to the bottom plate of upper lock head in Qingyuan second-line ship lock. The practice has shown that the maximum internal temperature and temperature falling velocity of the concrete inside the bottom plate of upper lock head are all controlled within the allowable range,which fully verifies the scientificity and applicability of technical methods such as"full-time water cooling during temperature rise stage to reduce the maximum temperature,intermittent water cooling during temperature drop stage to control water flow and temperature falling velocity"and the control of termination time for water cooling. What is more,the intelligent control device can easily be operated and relied on in performance. Consequently,the adopted methods and techniques deserve further promotion and application.
