Bolt end head is connected through the bolt hole on locating piece and stator sole plate with nut, has poured two between steel box and foundation bolt
Phase concrete.
In aforementioned structure, described grout pipe and grout outlet are right-angle elbow pipe, and one end is welded with steel box, and the other end is from stator
Pedestal top is stretched out.
In aforementioned structure, described steel box be shaped as up-small and down-big taper or wedge shape.
In aforementioned structure, described stator base and locating piece are reinforced concrete structure, and stator base top is provided with scarce
Mouthful, the reinforcing bar in locating piece is fixed on indentation, there with the reinforcement welding in stator base.
Owing to have employed technique scheme, compared with prior art, this utility model globality is relatively strong for this utility model,
Can be effectively improved stator foundation and machine pier rigidity, and reduce the vibration of unit, run for unit long-term safety and provide guarantor
Barrier.It addition, this utility model material requested is conventional material, easily purchase, simple in construction, and convenient and quick construction, convenient
Maintenance, can be easily accomplished the laying of foundation bolt.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in figure: 1 stator base, 2 locating pieces, 3 stator sole plates, 4 steel boxes, 5 grout pipes,
6 grout outlets, 7 foundation bolts, 8 nuts, 9 packing rings, 10 second stage concretes.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as new to this practicality
Any restriction of type.
A kind of powerhouse of hydropower station stator foundation structure of the present utility model, as it is shown in figure 1, a kind of powerhouse of hydropower station stator base
Plinth structure, including stator base 1, stator base 1 top is provided with locating piece 2, and locating piece 2 top is provided with stator sole plate 3；Stator
Being provided with steel box 4 in pedestal 1, the bottom of steel box 4 side is provided with grout pipe 5, and the top of steel box 4 side is provided with grout outlet 6, steel box 4
Inside being provided with foundation bolt 7, foundation bolt 7 two ends are equipped with nut 8 and packing ring 9, and foundation bolt 7 top is through locating piece 2 and determines
Bolt hole on sub-soleplate 3 is connected with nut 8, has poured second stage concrete 10 between steel box 4 and foundation bolt 7.Grout pipe 5
Being right-angle elbow pipe with grout outlet 6, one end is welded with steel box 4, and the other end stretches out from stator base 1 top.Being shaped as of steel box 4
Up-small and down-big taper or wedge shape.Stator base 1 and locating piece 2 are reinforced concrete structure, and stator base 1 top is provided with scarce
Mouthful, the reinforcing bar in locating piece 2 is fixed on indentation, there with the reinforcement welding in stator base 1.
Of the present utility model a kind of powerhouse of hydropower station stator foundation casting method for said structure is: will be pre-machined
Get well and be provided with the steel box 4 of grout pipe 5 and the taper of grout outlet 6 or wedge shape and put into and also do not carry out the stator base that fist stage concrete pours
In seat 1, make, on the reinforcing bar of the fist stage concrete that steel box 4 is fixed on stator base 1, then to carry out a phase coagulation of stator base 1
Soil pours, and after the fist stage concrete of stator base 1 has poured, foundation bolt 7 is put into steel box 4, and by solid for locating piece 2
It is scheduled on the top of foundation bolt 7, in the stator base 1 simultaneously reinforcing bar in locating piece 2 and fist stage concrete poured
