In aforementioned structure, the stator base and locating piece are reinforced concrete structure, are equipped with and lack at the top of stator base
Mouthful, the reinforcement welding in reinforcing bar and stator base in locating piece is fixed on indentation, there.
A kind of powerhouse of hydropower station stator foundation casting method of the invention for above structure is, by it is pre-processed simultaneously
The steel box of taper or wedge shape equipped with grout pipe and grout outlet, which is put into, not to carry out in the stator base that fist stage concrete pours also, makes
Steel box is fixed on the reinforcing bar of the fist stage concrete of stator base, then carries out the fist stage concrete for pouring stator base, undetermined
After the completion of the fist stage concrete of sub-base pours, foundation bolt is put into steel box, and locating piece is fixed on foundation bolt
Top, while by the reinforcing bar in locating piece together with the reinforcement welding in the stator base that fist stage concrete pours completion；To
The fist stage concrete for pouring stator base pours finish and reach design age after, it is mixed that the second phase is poured into steel box by grout pipe
Solidifying soil fills up second stage concrete in steel box.
Effect preferably is poured in order to reach, when pouring second stage concrete into steel box by grout pipe, makes to pour two
The slurries of phase concrete are in the milk from the lower curtate of steel box toward eminence sequence, 1~2 point of Reperfu- sion after slurries are from grout outlet spilling
Clock slurries can terminate to be in the milk after the slurries overflowed are underflow.
By adopting the above-described technical solution, compared with prior art, the present invention globality of the present invention is stronger, it can be effective
Ground improves stator foundation and machine pier rigidity, and reduces the vibration of unit, provides guarantee for the operation of unit long-term safety.In addition,
Material requested of the present invention is common material, is easily purchased, and structure is simple, and convenient and quick construction, convenient to overhaul, can be easily complete
At the laying of foundation bolt.
