无粘结预应力混凝土在圆形水池中的应用

Application of Unbonded Prestressed Concrete in Circular Pool

社会发展影响下,人们生产生活中的用水需求越来越大,对于污水处理量也大大增加。污水处理当中,初沉沉淀池、二沉池等池体的容积也越来越大。传统的水池设计中其水压和温度应力将会对水池壁产生较大的环拉力;此外,其将导致水池自身整体性差、抗震性、耐久性差,影响圆形水池的长久使用,文章基于无粘结预应力混凝土技术对圆形水池的设计进行分析,以实际的工程案例为依据,对无粘结预应力混凝土的广泛应用提供参考。

Under the influence of social development, the demand for water in production and life is increasing, and the amount of sewage treatment is also greatly increased. In the sewage treatment, the volume of the pool body such as the primary sedimentation tank and the secondary sedimentation tank is also increasing. In the traditional pool design, the water pressure and temperature stress will produce a large ring tension on the pool wall;in addition, it will result in poor overall stability, shock resistance and durability of the pool itself,affecting the long-term use of the circular pool. The prestressed concrete technology is used to analyze the design of the circular pool. Based on the actual engineering case, it provides reference for the wide application of unbonded prestressed concrete.
