| Abstract: | The unbonded prestressed swimming anchor angle tension technology is applied to the prestressed construction of circular hydraulic structures. The technology was used in the construction of egg-shaped digester of Wuhan Sanjintan WWTP. The embedment of unbonded tendons,the calculation of elongation value,the key points in construction of swimming anchor angle tension and so on are introduced,providing a reference for relevant construction. |
