Hydro-generator stator foundation plate fixing and pouring method
The invention discloses a hydro-generator stator foundation plate fixing and pouring method. The hydro-generator stator foundation plate fixing and pouring method comprises the following steps: (1) screwing a foundation screw and a lower nut into a whole; (2) sleeving a gasket and the foundation screw; (3) hoisting a stator foundation plate to a position above the foundation screw; (4) uniformly mounting foundation base plates and adjusting wedge plates; (5) arranging a funnel type grouting pipe and a vibrating rod; (6) enabling the stator foundation plate to fall down and placing the stator foundation plate on the adjusting wedge plates; (7) adjusting the stator foundation plate; (8) adjusting the level and the high level, tensioning the stator foundation plate and performing spot weldingfirmly; (9) extending the lower part of the funnel type grouting pipe into the lower part of the foundation screw; and (10), after the stator foundation plate is fixed in a foundation pit fan cover,grouting concrete grout into the foundation pit fan cover. The stator foundation plate can be firmer, it is guaranteed that the stator foundation plate is not affected by the pressure generated duringconcrete pouring in the pouring process, it is guaranteed that pouring is uniform and compact in the horizontal area, the high-rise area and the local area, and the safety and stability of a unit areguaranteed.
本发明公开了一种水轮发电机定子基础板固定、浇注方法，包括如下步骤：1）将地脚螺杆和下部螺母拧紧成一体；2）套入垫圈和地脚螺杆；3）把定子基础板起吊至地脚螺杆上方；4）均匀安装基础垫板和调整楔子板；5）设置漏斗式灌浆管及振动棒；6）将定子基础板落下，并放在调整楔子板上；7）调整定子基础板；8）调整好水平和高层，拉紧定子基础板并点焊牢固；9）将漏斗式灌浆管的下部伸入到地脚螺杆下部；10）待定子基础板固定在基坑风罩内后，将混凝土浆灌入。本发明不但能够使得定子基础板更佳牢固，而且在浇注过程中，保证定子基础板不受混凝土浇注时压力的影响，确保水平和高层，局部区域浇注均匀密实，保证了机组的安全稳定性。
