Specific implementation mode
The technique effect of the design of the present invention, concrete structure and generation is described further below with reference to attached drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
Embodiment：
Referring to Fig.1, Fig. 2, Fig. 3, the present invention include cast-in-place building entirety raft foundation 1, the building raft foundation 1
The foundation bolt 7 of the pre-buried matrix arrangement in position of upper setting main transformer is built on the basis of raft plate 1 described in this example along length
Four row's foundation bolts 7 of the pre-buried setting in direction, two foundation bolts 7 of often row's setting.Backing plate 8, institute are set on the foundation bolt 7
Setting foundation pile 5 on backing plate 8 is stated, 5 top connecting cross beam 4 of the foundation pile, the capital of the foundation pile 5 is along 1 base of building raft plate
The length direction welding setting track girder 3 of plinth, the track girder 3 use steel I-beam.The track girder 3 is vertical with crossbeam 4 to be set
It sets, oil pit wall card slot is preset on the building raft foundation 1 around the main transformer, oil pit wall 2 is placed in the card slot, institute
It states and fills waterproof material 9 between oil pit wall 2 and card slot.
With reference to Fig. 4, grill bearing part 12 is set on the track girder 3, cobble grid is set on the grill bearing part 12
10, the cobble grid 10 is interior to be arranged cobble 11.
With reference to Fig. 5, built-in connection 6 is arranged in the corresponding position that the oil pit wall 2 pushes up, and the connector 6 is welded to connect institute
State crossbeam 4 and track girder 3.These beams can be welded or are bolted.
The construction procedure of the present invention：
1, before the raft foundation of substation's building pours, in the foundation bolt of the pre-buried main transformer foundation column in precalculated position
With the card slot of oil pit wall, later basic maintenance completion.
2, main transformer foundation column is installed at foundation bolt, main transformer foundation column is two rows, one group of a row, every group of component
Including two foundation columns, three crossbeams, this partial component is welded as a whole for prefabrication, transport to in-site installation.
3, after after 4 groups of foundation columns, installation is complete, the track girder of installation twice longitudinal direction, track girder can pass through with foundation columns
It is welded to connect.
4, oil pit siding, top of panels pre-embedded steel slab or built-in fitting are installed, it can be with crossbeam, track girder and grill bearing
Part is welded to connect.The pre-buried waterproof construction in end of siding side, such as Fig. 5.After first piece of siding is in place, bottom is put into card slot, inside
After being welded and fixed with beam, then second piece is lifted, lifted from the top down, the mutual clamping of waterproof connector of end, then third
Block, and so on.After all sidings install, line chart brushes one times waterproof material in the preformed groove of bottom raft plate, then uses again
Waterproof mortar fills groove.The brushing waterproof material at plate end connection again, then at the gap in two pieces of flashing members
Fill waterproof mortar.
5, siding has just had main transformer mounting condition after installation is complete.After installation is complete after main transformer, both sides up and down are placed
Flase floor is then paved with cobble on flase floor, in order to oil strain and fire prevention.
Advantages of the present invention：
1, main transformer foundation integral assembling technology is used, raft foundation is built combining, overcomes previous prefabricated main transformer base
Plinth must make the deficiency that isolated footing can not be combined with building raft foundation, and raft plate top is needed to the basis of cast-in-place completion
Quantities is all changed to prefabrication and assembly construction, 80% or more the duration of main transformer foundation subdivisional work can be saved using this patent maximum, together
When do not influence subsequent handling；
2, the assembled completion together with main transformer oil pit by main transformer foundation, improves previous only prefabricated main transformer foundation and oil pit must
The deficiency that must finally construct after installation is complete in main transformer equally greatly improves efficiency and saves the duration；
3, crossbeam is not only arranged in the application, is also provided with long rails beam, and entire foundation columns form frame with beam body system
System, structural stability is good, and bearing capacity is strong, and more previous mass concrete main transformer foundation saves 60% amount of concrete；
4, track girder be not only able to keep stablize, while can also serve as main transformer transporting and hoisting it is in place during track, just
Do not have to individually set up conveying track again when position, relatively previous prefabricated main transformer foundation improves the efficiency of transportational process；
5, due to oil pit wall is too long can not be integral prefabricated, need to assemble after being segmented prefabricated transport to scene.Several pieces of assemblings
When, this card slot waterproof is all used between every two pieces, the right-angle side and opposite side Novel clamping slot waterproof that oil pit wall surrounding wallboard uses
Technology can effectively ensure that water resistance of the basis after installation is complete, oil pit oil leak probability substantially reduce.
6, track girder uses steel I-beam, and after main transformer is in place, flange plate can also serve as cobble lattice at the top and bottom of track girder
The scrap (bridge) of grid, a material is multi-purpose, improves later stage efficiency of assembling.
This patent is a kind of technology can be widely applied to indoor substation main transformer foundation construction, has wide answer
Use foreground.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel can be obtained by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
