Field Monitoring of Temperature and Deformation in a Settling Tank of Xiqu Water Treatment Plant in Fuzhou
To investigate the causes of water leakage at expansion joints of ultra-long water tanks and uncover the temperature and deform-ation characteristics of these tanks,a field monitoring approach was employed using a settling tank at the Fuzhou Xiqu Water Plant as a case study.Meteorological data,temperature at expansion joints,and deformation of the tank structure were monitored for a period of one year,fol-lowed by comparative analysis.The results show that during high temperatures in summer,the highest temperature at a depth of 5cm is 5.4%higher than that at a depth of 10cm,while during low temperatures in winter,the lowest temperature at 5cm depth is 3.9%lower than that at 10cm depth.Under the influence of seasonal temperature differences,the maximum expansion displacement of the tank accounts for 9.1%of the maximum deformation limit of the tank.
