In the second phase of Chengdu Sewage Treatment Plant, the sludge digester has an inner diameter of 27 m and a height of 20 m, a total of four. In the design of the structure, a ring-bound unbonded prestressed structural design was adopted to meet the requirement of large Diameter and high water level digester cylinder shell ring to the higher pre-stress requirements, and achieved good economic and technical indicators. This article briefly introduces the design and construction of pre-stressing section of this digester
