The specific embodiment
Embodiment of the present utility model: the structure of a kind of strong vibration giant mechanical and electrical equipment pre-embedded bolt of the present utility model makes up as follows, and as shown in Figure 1, this method is to precoat to be provided with the cavity body of movable bolt in Equipment Foundations; Earlier movable bolt is connected with the fixed base plate of equipment during erection equipment, the cast of movable bolt is finished in the grout pipe of the bottom by the being located at cavity body grouting of pressurizeing in cavity body then.The described pressurization in cavity body when being in the milk, the air in the cavity body is discharged by being located at cavity body top return pipe, when return pipe is discharged cement mortar continuously, finishes the cast of movable bolt.In the method to set up of aforementioned strong vibration giant mechanical and electrical equipment pre-embedded bolt, the cement strength grade of described cement mortar is greater than 32.5, and water/binder ratio is 0.5～0.6, the sand amount of mixing of cement mortar be not more than cement heavy 200%, the little 2.5mm of the particle diameter of sand, fineness modulus is not more than 2.0.Described cavity body comprises steel box and steel pipe; Be provided with billet in the steel box, billet is provided with bolt hole and through hole, is installed with bolt in the bolt hole; Steel pipe socket is on bolt; Steel pipe one end and the welding of steel box.Described bolt or billet can have the displacement of 10～20cm respectively in the cavity of steel pipe socket or steel box.The diameter of described grout pipe and through hole is greater than 38mm.
The structure of the strong vibration giant mechanical and electrical equipment pre-embedded bolt of the present utility model of Gou Jianing according to the method described above, as shown in Figure 1, this structure comprises the cavity body that is located in the Equipment Foundations 1, and the cavity body bottom is provided with grout pipe 2, and cavity body top is provided with return pipe 3; Be provided with bolt 4 in the cavity body.Described cavity body comprises steel box 5 and steel pipe 6, steel pipe 6 and 5 welding of steel box; Be provided with billet 7 in the steel box 5, billet 7 is provided with bolt hole 8, is provided with one group of through hole 9 along bolt hole 8 peripheries.Between described steel box 5 and the billet 7, and the gap of leaving 10～20cm between steel pipe 6 and the bolt 4; Be provided with cement mortar 10 in the gap.The diameter of described grout pipe 2 and through hole 9 is greater than 38mm.
Implementation process of the present utility model is as follows:
As shown in Figure 1, the first step is made cavity body, and cavity body comprises steel box 5 and steel pipe 6.Steel box 5 steel plate welding forming, steel box 5 are made rectangle or other non-circular box body, and be rotatable after being cast in the Equipment Foundations 1 to prevent steel box 5.A dress billet 7 in steel box 5, billet 7 is also made rectangle or non-circular, rotates in the cement mortar 10 of solidifying to prevent billet 7.Billet 7 is provided with bolt hole 8, is provided with one group of through hole 9 around the bolt hole 8, so that cement mortar 10 can enter in the steel pipe 6 by through hole 9.Be installed with bolt 4 in the bolt hole 8 of billet 7, the bolt head of bolt 4 is that hexagon or other are non-circular, to prevent when screwing nut 11 and then rotation of bolt 4.Binding of weldable steel box 5 tops bound and left the hole then, and steel pipe 6 is welded in the hole at steel box 5 tops.Billet 7 can have the displacement of 10～20cm in steel box 5.Bolt 4 can have the displacement of 10～20cm in steel pipe 6.At steel box 5 bottoms welding grout pipe 2, at the welded top return pipe 3 of steel pipe 6, the mouth of pipe of grout pipe 2 and return pipe 3 is higher than the mouth of pipe of steel pipe 6.The diameter of grout pipe 2 and through hole 9 is convenient to cement mortar 10 and is passed through smoothly greater than 38mm.
Second step was embedded in the above-mentioned ready-made cavity body that has movable bolt in the Equipment Foundations 1, made the port of steel pipe 6 concordant with the last plane of Equipment Foundations 1 when pre-buried.The mouth of pipe of grout pipe 2 and return pipe 3 should be higher than the last plane of Equipment Foundations 1.Casting equipment basis 1 o'clock, the mouth of pipe of reply grout pipe 2, return pipe 3 and steel pipe 6 is carried out safeguard measure, prevents that concrete from entering grout pipe 2, return pipe 3 and steel pipe 6.After finishing, Equipment Foundations 1 cast just guarantees that bolt 4 can have the displacement of 10～20cm in steel pipe 6.
The 3rd step, after the concrete for the treatment of Equipment Foundations 1 reaches and solidifies fully the length of time, carry out the location and installation of equipment, because bolt 4 can be movable in steel pipe 6, therefore can adjust the accurate location between bolt position and the equipment fixing hole, be connected with bolt 4 by the fixed head 12 of nut 11, accurately locate with assurance equipment with equipment.
In the 4th step, after the equipment for the treatment of is accurately located, take the mode of pressure injection in steel box 5, to inject cement mortar 10 by grout pipe 2.The cement strength grade of cement mortar 10 is greater than 32.5, and water/binder ratio is 0.5～0.6, the sand amount of mixing of cement mortar be not more than cement heavy 200%, the little 2.5mm of the particle diameter of sand, fineness modulus is not more than 2.0.Cement mortar 10 is injected steel pipe 6 by the through hole on the billet 79, and the air in the steel pipe 6 is discharged by return pipe 3, goes out cement mortar 10 up to return pipe 3 continuous stream, can stop the cement injection mortar.Grouting finishes just can carry out after 28 days the debugging or the operation of hydrogenerator.
