To achieve the above object, the utility model is adopted the following technical scheme that：
The steam turbine generator spring vibration-isolated foundation of combined layout, including Foundation of Steam Turbogenerater top platen, spring vibration-isolator
And the supporting structure below spring vibration-isolator；Turbo-generator Set is seated on Foundation of Steam Turbogenerater top platen, spring vibration isolation
Device is arranged between Foundation of Steam Turbogenerater top platen and supporting structure；Mill construction is overall around supporting structure and vibro-damping mount
Combined layout.
Further, the supporting structure includes what is supported the frame column of spring vibration-isolator and be connected with mill construction around
The less bracket column in section, generally L-type structure.
Further, spring vibration-isolator is made up of array steel spiral cylinder spring, and power consumption is provided with partial spring vibration isolator
Damper device.
Further, supporting structure is structure as a whole with mill construction around vibro-damping mount.
Further, Foundation of Steam Turbogenerater top platen is concordant with mill construction horizontal plane around vibro-damping mount.
Further, Foundation of Steam Turbogenerater top platen uses monolithic reinforced concrete structure.
Further, spring vibration-isolator is directly seated in the framework capital of supporting structure.
Further, in middle tier platform, the mill construction with around is joined directly together the frame column of supporting structure.
Compared with traditional vibro-damping mount, the utility model has the following technical effect that：
1st, because spring support structure and surrounding mill construction have carried out combined layout, the lateral firm of factory building entirety is added
Degree, can effectively reduce the horizontal displacement of top platen；The arrangement of factory building can be optimized, more skies are provided for process pipe arrangement
Between；
2nd, the horizontal rigidity of mill construction can be improved, anti-seismic performance is improved；
3rd, by the way that vibro-damping mount top plate is reached into the basic platform of reduction with lower support structure and surrounding mill construction combined layout
Plate level, so as to reduce the width of movement joint between foundation sole plate and surrounding floor, can save factory building knot to the purpose of displacement
Structure gross investment；
4th, the utility model also has simple mill construction arrangement, excellent earthquake resistance, reduced investment outlay, and shortens the duration etc. excellent
Point, be particularly suitable for use in Areas of High Earthquake Intensity area, pipe level thrust it is larger when spring vibration-isolated foundation.
5th, spring vibration-isolator can effectively reduce the natural frequency of vibration of pedestal top platen, make it away from generating set and normally run
When frequency；The vibration produced during other generating set operation is largely isolated, and spring is subjected only to vapour with lower support structure
The dead load of turbine generator group.
