Composite steam turbine generator spring foundation

The utility model discloses a combined type turbonator spring foundation which comprises a turbonator foundation top platen, a vertical spring vibration isolator, a vibration isolation support and a horizontal limiting device. Wherein the vertical spring vibration isolator is arranged below the steam turbine generator foundation top platen, the vibration isolation support is arranged at the bottomof the vertical spring vibration isolator, and the horizontal limiting device is arranged on the side face of the steam turbine generator foundation top platen; the lead core shock isolation rubber support is arranged at the lower part of the spring vibration isolator, so that vertical equipment vibration of the top bedplate can be isolated; the effect of reducing the horizontal earthquake actionof the foundation top bedplate can be achieved, the purpose of reducing the horizontal displacement of the foundation bedplate is achieved by laterally arranging high-damping rubber limiting devicesaround the foundation top b
