绕丝预应力圆形水池的加固设计

REINFORCEMENT DESIGN OF WIRE-AND-STRAND-WRAPPED CIRCULAR PRESTRESSED CONCRETE TANKS

根据绕丝预应力圆形水池的施工特点和建造时期的条件,分析了该类型水池的钢丝容易被腐蚀的原因,提出了应对按此类型建造的水池开展安全性普查的必要性。同时根据圆形预应力水池的受力特点和东北寒冷地区的状况,给出了采取环梁加固绕丝预应力圆形水池的方法。该方法施工简便、安全可靠。

Based on construction characteristics and years of wire-and-strand-wrapped circular tanks,this paper analyzed the reasons for corrosion of steel wire in such kind of pond and discussed the necessity for safety inspection of this kind of tanks.Meanwhile,the reinforcement method for wire-and-strand-wrapped circular tanks by using ring beam was introduced according to its stress characteristics of circular tanks and the cold weather in the Northeast China.It was proved that the reinforcement method is convenient,safe and reliable.
