Description
Technical field
The utility model relates to and send power transformation technical field, specifically relates to a kind of transformer station's reactor basis, high mountain permafrost area that is applicable to.
Background technology
High mountain permafrost regional geology condition is comparatively special, due to frost heave, the thaw collapse characteristic of frozen soil, and the disease that permafrost region structure base ubiquity is serious: freezing period basis generation differential frost heave, causes foundation deformation, crack; Thawing phase yielding of foundation, brings great difficulty to the safe operation of structure.Investigation shows, In Permafrost Regions of Qinghai-xizang Plateau structure disease more than 80% is sunken the causing of hot thaw collapse due to basic bottom ever-frozen ground.The ever-frozen ground of Qinghai-Tibet Platean belongs to High Temperature Permafrost mostly, is very easily subject to Engineering Disturbance to affect generation thaw subsidence.
Tradition high mountain permafrost area reactor adopts reinforced concrete pile cap pile foundation, this type of basis can produce very strong endothermic effect, and cushion cap foundation buried depth large (3.0m) there is the larger coefficient of heat conduction (2.34W/mK), can directly the heat on ground be imported into rapidly and intensively underground, promote the thawing of stake week and its underpart ever-frozen ground layer, further accelerate to melt the formation of funnel, under the effect of the unbalanced load in reactor basis, the trend of reactor basis run-off the straight is further increased.
High and cold and the severe depletion of oxygen in " Wu Daoliang 110kV transformer station " their location more than height above sea level 4000m, the temperature difference utmost point, wind speed is large, solar radiation is strong, and freezing period is more than 8 months, is known as the transmission and transformation engineering in life forbidden zone.According to the five Dao Liang weather station observational datas of 1959～1980 years, this section of average temperature of the whole year is-5.6 ℃, and 1 monthly mean temperature is-16.9 ℃, and 7 monthly mean temperatures are 5.4 ℃, average temperature of the whole year is poor is 22.3 ℃, and it is 243 days that daily mean temperature is less than or equal to the number of days of 0 ℃.Mean annual precipitation is 264.8mm, and a year maximum snow depth is 14cm.
To equipment safety operation in transformer station, there is very large hidden danger in the depression on reactor basis, especially along with the unmanned of transformer station's employing in recent years pattern, for equipment Foundations, cannot accomplish Real-Time Monitoring, therefore effectively solve high mountain permafrost area reactor yielding of foundation problem extremely urgent.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and a kind of transformer station's reactor basis, high mountain permafrost area that is applicable to is provided.
A kind of transformer station's reactor basis, high mountain permafrost area that is applicable to of the utility model is achieved by following technical proposals: a kind of transformer station's reactor basis, high mountain permafrost area that is applicable to comprises foundation columns, plain concrete, built-in fitting, described foundation columns is straight angle equilateral triangle for adopting plain concrete to pour into a mould the hollow plan view shape forming, and foundation columns top arranges built-in fitting.
A kind of transformer station's reactor basis, high mountain permafrost area that is applicable to of the utility model has following beneficial effect compared with prior art: advantage of the present utility model: 1. reactor basis adopts plain concrete basis, substitute conventional reinforced concrete foundation, reduce coefficient of thermal conductivity, slow down dredging of earth's surface heat, reduce the pile body intensification of the ever-frozen ground soil body around and melt;
2. reactor basis adopts plain concrete basis, improve dielectric level, elimination is due to equipment leakage or produce electromagnetism circulation and cause reinforced concrete foundation to become a persistent fever body, pile peripheral earth is played to heat effect, thereby cause all ever-frozen ground of stake to melt and cause reactor basis that the hidden danger of thaw collapse, unstability occurs;
3. high mountain permafrost area foundation soil freezes deeply larger, embeded depth of foundation is had higher requirements, adopt three-pointed hollow star to arrange reactor basis, according to force analysis, can bear the dynamic and static load of equipment, and effectively keep out ground earth lateral pressure, stressed suitable with deposited reinforced concrete pile basis, but saved amount of reinforcement;
4. adopt three-pointed hollow star to arrange reactor basis, basic material consumption amount is saved more than 50% in more traditional basis, and economy is more reasonable.

Fig. 1 is a kind of high mountain permafrost area transformer station reactor foundation structure schematic diagram that is applicable to of the utility model;
Fig. 2 is a kind of transformer station's reactor basis, high mountain permafrost area sectional structure schematic diagram that is applicable to of the utility model;
Fig. 3 is a kind of high mountain permafrost area transformer station reactor basis instrument structural representation that is applicable to of the utility model.
Wherein: 1, foundation columns; 2, plain concrete; 3, built-in fitting; 4, foundation ditch.
The specific embodiment
Below in conjunction with drawings and Examples, a kind of high mountain permafrost area transformer station reactor basic technology scheme that is applicable to of technical scheme utility model is further described.
As shown in Figure 1-Figure 3, a kind of transformer station's reactor basis, high mountain permafrost area that is applicable to of the utility model comprises foundation columns 1, plain concrete 2, built-in fitting 3, the plan view shape that described foundation columns 1 adopts plain concrete 2 cast to form is hollow straight angle equilateral triangle, and foundation columns 1 top arranges built-in fitting 3.
The cylinder section of described foundation columns 1 is inverted T shape.
Described foundation columns 1 is set to association type triangle in reactor foundation pit 4.
Described built-in fitting 3 is arranged on the foundation columns 1 leg-of-mutton corner positions in top.
The utility model is a kind of, and to be applicable to the plan view shape that the foundation columns 1 described in transformer station's reactor basis, high mountain permafrost area adopts plain concrete 2 cast to form be hollow straight angle equilateral triangle, the base shape that cylinder section is inverted T shape, as shown in Figure 2; And the built-in fitting 3 of constant reactance device equipment is set at foundation columns 1 top.Built-in fitting 3 is arranged on the straight angle position of foundation columns 1 top three-pointed hollow star.As shown in Figure 1, Figure 3
Because the utility model reactor basis adopts plain concrete basis, substitute conventional reinforced concrete foundation, reduced coefficient of thermal conductivity, slow down dredging of earth's surface heat, reduced the pile body intensification of the ever-frozen ground soil body around and melted; Solved Frozen Ground Area structure base because the original fuel factor that adopts steel concrete to produce makes ever-frozen ground heat melt the problem that causes yielding of foundation;
