Abstract
The invention provides a combined raft foundation of an outdoor framework and GIS (geographic information system) equipment in a transformer substation. Framework foundations and a GIS raft foundation form a mat foundation, wherein the burial depth of each framework foundation is increased in consideration of the load difference of the GIS equipment and a framework rod, and meanwhile, the top of the framework foundation is slightly higher than a raft so as to facilitate connection between a foundation embedded bolt and each A-shaped rod framework column. According to the invention, the top of the GIS mat foundation is elevated to the position which is as high as minus 0.3 m, and the two framework foundations and the raft foundation of the GIS equipment are arranged in a combined manner to form the mat foundation. Through adoption of the combined raft foundation, the problem of foundation collision between the framework and the GIS equipment is solved, the land occupied by the transformer substation and the foundation capacity are reduced, and the project investment is saved.
Description
Technical field
The present invention relates to be in a kind of transformer station outdoor framework basis with GIS device combine raft foundation, belong to the design arrangement formal technique field of transformer station.
Background technology
Substation Design is after adopting unified general module, in enclosure wall, floor space becomes a unalterable quota and must not break through, but different sizes is taken up an area on the basic arrangement form of various geological conditions demand and basis, under limited space lining is put, the most fat natural ground single footing becomes a stubborn problem.Shown in Fig. 1, transformer station's outlet structure generally adopts A font bent structure, all establishes single footing to two posts of A word bar truss column in the past, bears pressure and pulling force respectively, meet resistance to compression and resistance to plucking requirement during natural ground; Then vertical load is comparatively large, apparatus arrangement is intensive for GIS device, and equipment room does not allow to there is differential settlement, often takes raft foundation arrangement form; In order to allow framework basis throw off completely with GIS foundation, the distance between framework and GIS device need be strengthened, causing transformer station's enclosure wall inner area and square foundation amount to increase all to some extent.If characteristic value of foundation bearing capacity is 100kPa, in standing, place backfill 1.0m is dark, (this method is applicable to basis, 110kV place arrangement form to 220kV outlet structure center pillar equally, every data have change) adopt traditional single footing size to need 3.0m (wide) X3.4m(long) X2.5m(is dark), reserve top A word bar framework root to open, framework center line must with the large plate base of GIS ensure 3731 distance, ensure not collide in each basis of distance guarantee of 4351 with enclosure wall center line, also operation side will be considered simultaneously, about need 9.0m space can ensure framework basis smooth construction, and universal design also only reserves 7.9m space after considering to utilize equipment gap.Once transformer station's enclosure wall line repeatedly need be proved and illustrated and hand over review activities to authorize after breakthrough universal design, program is more loaded down with trivial details, easily delays the transformer substation construction duration.If do not change large enclosure wall inside dimension, the space that framework single footing and GIS raft foundation depart from completely cannot be stopped in narrow and small enclosure wall line, therefore this binomial basis of ingenious reasonable Arrangement is the difficult point of engineering construction, the key of later stage transformer substation power distribution unit safe and reliable operation especially.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned existence, a kind of basic arrangement form optimized in power distribution equipment is provided, reduce transformer station to take up an area and square foundation amount, strengthen the resistance to compression of framework, breakout capacity, reduce embedded depth of foundation, solve the phenomenon that underground in site enclosure wall is narrow, collide in basis, realize investment reduction, reduce expropriation of land, do not break through transformer station that State Grid Corporation of China's universal design takes up an area the objects such as unalterable quota in outdoor framework and GIS device combine raft foundation.
The object of the invention is to have come by following technical solution, it framework basis is formed whole plate base with GIS raft foundation arrange, wherein consider GIS device with truss bar different loading, framework base position buried depth is deepened, slightly exceed raft plate at top simultaneously, facilitate foundation built-in bolt to be connected with A word bar truss column.
The present invention is increased to-0.3m place by high for whole for GIS plate base top mark, and the raft foundation combined layout of two frameworks basis and GIS device is formed whole plate base.
The present invention, by after theory calculate and field practice, simultaneously by both mode process different loading on local deepened basis, solves framework and the basic problem of colliding of GIS device, decreases transformer station and take up an area and square foundation amount, saved construction investment.
Accompanying drawing explanation
Fig. 1 is existing conventional architecture and GIS device foundation layout plan.
Fig. 2 is framework of the present invention combines raft foundation layout plan with GIS device.
Fig. 3 is 220KV outgoing line interval profile of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 2,3, the present invention is increased to-0.3m place by high for whole for GIS plate base 1 top mark, framework basis 2 forms whole plate with GIS raft foundation 3 and arranges, consider GIS device with truss bar different loading, framework base position buried depth is deepened, slightly exceed raft plate at top simultaneously, facilitate foundation built-in bolt to be connected with A word bar truss column 4.After outlet tensioning equipment is in place, mass-type foundation take part in the resistance to plucking of framework and resistance to compression work also assume responsibility for GIS device load.
The invention provides a kind of new approaches, namely employing underground foundation is rationally whole waters on (framework and GIS device basis), solve the structure base of land area when cannot expand to collide problem, framework is adopted to combine after raft foundation with GIS device, enhance the resistance to compression of outlet structure, resistance to plucking, resistance to capsizing, decrease the differential settlement on GIS device basis, reduce the issuable risks of bad nature of soil such as the loss of the basic infrastructure soil body, liquefaction.Raise embedded depth of foundation, saved basic material, reduce foundation excavation face, reach the object reducing transformer station's expropriation of land and reduce basic material.
