Abstract
The utility model discloses a general type main transformer foundation. Due to the fact that a foundation beam and a foundation bottom plate of a traditional main transformer foundation are poured together, once a construction is completed, the size of the foundation beam can not be adjusted, the investment of the reconstruction project of a transformer substation is increased, and the construction period of the main transformer foundation is usually limited by a concrete curing time. The general type main transformer foundation is characterized in that a plurality of parallelly arranged concrete foundation beams are arranged on the reinforced concrete bottom plate poured on site, adjacent concrete foundation beams are connected through a plurality of guide distance adjusting blocks, the concrete foundation beams positioned on an outer side are connected with the reinforced concrete bottom plate through end portion connection blocks, and the concrete foundation beams, the guide distance adjusting blocks and the end portion connection blocks are all preformed units. According to the general type main transformer foundation, only the guide distance adjusting blocks and the end portion connection blocks need to be changed to complete the adjustment of the main transformer foundation beam in a main transformer foundation replacing process, compared with the traditional main transformer foundation, the construction period is greatly reduced, and power off time is reduced.
Description
Technical field
The utility model relates to the transformer substation foundation facility, specifically the universal main transformer of a kind of 220 kv substations basis.
Background technology
Along with expanding economy, the growth at full speed of power load, increasing transformer station is because the growth of power load needs to change the growth that main transformer satisfies power load.The guide rail distance of finding 220 kv substation main transformers in changing the Project design process of main transformer is not definite value, and the distance of main transformer guide rail can change along with the variation of the variation of main transformer capacity, main transformer manufacturer.Then because generation main transformer production year is more remote, although be same manufacturer production, because the main transformer structure changes, producer can't finish the production with the gauge main transformer for some.The spacing of transforming plant main transformer grade beam and quantity are determined by spacing and the quantity of main transformer guide rail, traditional main transformer foundation is poured into a mould with sole plate owing to grade beam, in case the grade beam size can't be adjusted after construction was finished, therefore in transformation process often under the condition that foundation bearing capacity and foundation settlement amount satisfy, because guide rail distance or quantity problem have to cut former main transformer foundation, become again complete design and the construction of gauge size according to new change owner, so not only increased the investment of Transfomer Substation Reconstruction engineering, and the construction period of main transformer foundation often limit by the concrete curing time, can't go to shorten the construction period by technological means at present, cause transformer station to have a power failure for a long time, bring larger economic loss.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of universal main transformer basis of each parts easy accessibility is provided, and to shorten the construction period, reduces power off time.
For this reason, the utility model adopts following technical scheme: universal main transformer basis, the reinforced concrete floor that comprises cast in situs, it is characterized in that, described reinforced concrete floor is provided with many concrete foundation beams that be arranged in parallel, adjacent concrete foundation beam adopts a plurality of guide rail spacing regulating blocks to connect, the concrete foundation beam that is positioned at the outside is connected with reinforced concrete floor by the end contiguous block, and described concrete foundation beam, guide rail spacing regulating block and end contiguous block are prefabricated component.
Further, have many draw-in grooves that be arranged in parallel on the described reinforced concrete floor, the setting party of draw-in groove to the perpendicular direction that arranges of concrete foundation beam, the sidepiece of concrete foundation beam forms many protuberances that the bottom placed draw-in groove, the logarithm of protuberance is consistent with the quantity of draw-in groove, adjacent protuberance adopts described guide rail spacing regulating block to connect, and described guide rail spacing regulating block places draw-in groove.
Further, adjacent protuberance is connected with guide rail spacing regulating block by the pre-embedded bolt on the concrete foundation beam.
Further, described end contiguous block is connected with reinforced concrete floor by bolt.
Further, described end contiguous block is connected with the concrete foundation beam by the pre-embedded bolt on the concrete foundation beam.
Build during reinforced concrete floor site operation of the present utility model, concrete foundation beam, guide rail spacing regulating block and end contiguous block are prefabricated component, on-the-spot installation construction, this main transformer foundation guide rail and reinforced concrete floor are that assembling combination is finished, easy accessibility, in changing the main transformer process, need only replacing guide rail spacing regulating block and end contiguous block and just can finish the adjustment of main transformer foundation beam, itself and main transformer gauge are adapted, compare greatly with traditional main transformer foundation and to have shortened the construction period, reduced power off time.

The specific embodiment
Universal main transformer basis as shown in the figure, reinforced concrete floor 1 is provided with 4 concrete foundation beams 2 that be arranged in parallel, adjacent concrete foundation beam adopts 3 guide rail spacing regulating blocks 3 to connect, the concrete foundation beam that is positioned at the outside is connected with reinforced concrete floor 1 by end contiguous block 4, described concrete foundation beam 2, guide rail spacing regulating block 3 and end contiguous block 4 are prefabricated component, build during the reinforced concrete floor site operation.
Have 3 draw-in grooves that be arranged in parallel 5 on the described reinforced concrete floor 1, the setting party of draw-in groove to the perpendicular direction that arranges of concrete foundation beam, the sidepiece of concrete foundation beam forms the protuberance 6 that 3 pairs of bottoms place draw-in groove, adjacent protuberance adopts described guide rail spacing regulating block to connect, and described guide rail spacing regulating block places draw-in groove.
Adjacent protuberance is connected with guide rail spacing regulating block by the pre-embedded bolt 7 on the concrete foundation beam.Described end contiguous block is connected with reinforced concrete floor by bolt 8.Described end contiguous block is connected with the concrete foundation beam by the pre-embedded bolt 9 on the concrete foundation beam.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all falls in the protection domain of the present utility model any simple modification, equivalent variations and modification that above embodiment does.
