Hydropower station volute outer wrapping concrete structure
The invention provides a hydropower station volute outer wrapping concrete structure comprising volute outer wrapping concrete. A base ring is arranged on one side of the volute outer wrapping concrete, and prestressed steel strands, vertical reinforcing steel bars and horizontal reinforcing steel bars are sequentially arranged on the other side of the volute outer wrapping concrete. A volute is arranged in the volute outer wrapping concrete. The volute is connected with the base ring. An elastic cushion layer is arranged on the outer side of the volute. According to the hydropower station volute outer wrapping concrete structure, concrete tensile force caused by loads is reduced or offset by exerting prestress on the volute outer wrapping concrete, and therefore tensile stress of structure components can be reduced, and while requirements of plants for structure rigidity and deformation control are met, the section size of the volute outer wrapping concrete is reduced as much as possible, the plant construction scale is reduced, and investment is reduced.
本发明提供了一种水电站蜗壳外包混凝土结构，包括蜗壳外包混凝土；蜗壳外包混凝土的一侧设有座环，另一侧依次设有预应力钢绞线、竖向钢筋和水平钢筋；所述蜗壳外包混凝土内设有蜗壳，蜗壳与座环连接，在蜗壳的外侧设有弹性垫层。本发明通过对蜗壳外包混凝土施加预应力来减少或抵消荷载所引起的混凝土拉力，从而使结构构件的拉应力减小，在满足厂房对结构的刚度和变形控制要求的同时，尽量减小蜗壳外包混凝土的截面尺寸，减小厂房土建规模，减少投资。
