Abstract
The utility model relates to an electric power facility field is specifically said to a length leg iron tower shank structure suitable for precipitous topography. Including the long legs that first tower leg owner material and the oblique material of first tower leg formed, short -leg that the oblique material of second tower leg and second tower leg owner material formed, the junction of the horizontal material setting of tabula on long legs and short -leg and iron tower, with the oblique material of first tower leg sets up a knick point, the level sets up a first tabula face between knick point and the first tower leg owner material, and the contained angle between oblique material of first tower leg and the first tower leg owner material is 20~30. The utility model discloses the discrepancy in elevation of multiplicable long legs and short -leg to adapting to more precipitous topography, avoiding base face shovel side, being favorable to soil and water conservation, reducing the influence to the environment, environmental protection and social are showing.
Description
Technical field
The utility model relates to electric power facility field, is particularly a kind of unequal leg steel tower leg structure being applicable to mountain terrain.
Background technology
Along with Environmental Protection in China consciousness and the improving constantly of environmental requirement, the designing technique of mountain area transmission line of electricity is also constantly updated thereupon, the particularly design on mountain area iron tower of power transmission line and basis, the flat leg of early stage employing steel tower combines the mode of excavation large platform, adopt steel tower unequal leg to combine the mode of excavation chain-wales afterwards, and mainly adopt steel tower unequal leg in conjunction with the mode of raw fly ash in recent years.
The appearance of steel tower unequal leg, is the large qualitative leap of mountain area Transmission Line Design one, greatly reduces the evolution amount of basal plane and the height of upper side slope.When terrain slope is less than 30 °, adopts steel tower unequal leg and raw fly ash matching design, substantially can accomplish not shovel basal plane; When terrain slope is larger, when the ground height of any two legs of steel tower is greater than the maximum discrepancy in elevation of steel tower unequal leg, when not considering other measures, then need the height being reduced short-leg ground by the side of shovel, to adapt to the maximum discrepancy in elevation of steel tower unequal leg, the high slope of shoveling square one-tenth leaves potential safety hazard to circuit, causes larger destruction, add soil erosion to environment.
The maximum discrepancy in elevation of unequal leg depends on how long long leg can do and how short short-leg can do, the unequal leg steel tower leg structure pattern generally adopted at present, the extreme length of its long leg is subject to the restriction of " the oblique material of tower leg and tower leg main material angle should not be less than 20 ° ", and the shortest length of its short-leg is subject to the restriction of " the oblique material of tower leg and tabula horizontal material angle should not be less than 35 ° ".
Utility model content
Technical problem to be solved in the utility model is to provide a kind of unequal leg steel tower leg structure being applicable to mountain terrain, increase the maximum discrepancy in elevation of steel tower unequal leg, to adapt to more precipitous landform, break through existing steel tower and be subject to the oblique material of tower leg and tower leg main material and the restriction with tabula horizontal material angle.
The utility model realizes like this, a kind of unequal leg steel tower leg structure being applicable to mountain terrain, comprise the long leg structure that the first tower leg main material and the oblique material of the first tower leg are formed, the short-leg that the oblique material of second tower leg and the second tower leg main material are formed, tabula horizontal material is arranged on the junction of long leg and short-leg and steel tower upper end, the oblique material of described first tower leg arranges a knick point, be horizontally disposed with one first tabula face between described knick point and the first tower leg main material, the angle between the oblique material of the first tower leg and the first tower leg main material is 20 ° ~ 30 °.
As the improvement of the utility model scheme, the first tower leg main material and the second tower leg main material are without knick point.
As the improvement of the utility model scheme, in long leg structure, the oblique material of the first tower leg and arrange near angle between the angle that the first tower leg main material is formed with the first tabula face that at least one is parallel with the first tabula face every face.
As the improvement of the utility model scheme, the oblique material of the first tower leg is upwards extended afterwards the knick point on the oblique material of the first tower leg and the angle on abrupt slope, place becomes large.
The utility model compared with prior art, beneficial effect is: compared with becoming length of grade leg with the nothing generally adopted at present, increase the angle of the crossing of the oblique material of tower leg and tower leg main material, oblique for tower leg material is once become slope by the utility model, the oblique material place of tower leg sets up tabula face, long leg arrange tabula face mode near column foot place, do not change the oblique material of short-leg tower leg and tabula horizontal material angle, this construction increases the cross-sectional area of long leg simultaneously, improve the integral rigidity of long leg, reduce the distortion of long leg.Such design can increase the discrepancy in elevation of long leg and short-leg, the impact to adapt to more precipitous landform, avoid basal plane shovel side, be conducive to water and soil conservation, reducing environment, environmental protection and social benefit remarkable.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See the device structure schematic diagram that Fig. 1 provides for the utility model one preferred embodiment, a kind of unequal leg steel tower leg structure being applicable to mountain terrain, comprise long leg 3 structure that the first tower leg main material 1 and the oblique material 2 of the first tower leg are formed, the short-leg structure that the oblique material 6 of second tower leg and the second tower leg main material 7 are formed, tabula horizontal material 5 is arranged on the junction of long leg and short-leg and steel tower upper end, the oblique material 2 of first tower leg arranges a knick point
The oblique material 2 of described first tower leg arranges a knick point 4, and the angle be horizontally disposed with between knick point 4 and the first tower leg main material 1 between the oblique material 2 of one first tabula face 11, first tower leg and the first tower leg main material 1 is 22 °.Ensure that short-leg angle remains on 35 ° simultaneously.
Meanwhile, on the first tower leg main material 1 and the oblique material 6 of the second tower leg main material 7, second tower leg, nothing becomes slope.
With between the first tabula face, the second tabula face 8 parallel with the first tabula face and the 3rd tabula face 9 are set in order to carry out reinforcing the angle formed at the oblique material of the first tower leg 2 and the first tower leg main material 1 near angle.
Compared with becoming length of grade leg with the nothing generally adopted at present, increase the angle of the crossing between the oblique material of the first tower leg and the first tower leg main material, add the cross-sectional area of long leg simultaneously, improve the integral rigidity of long leg, reduce the distortion of long leg.Such design can increase the discrepancy in elevation of long leg and short-leg, to adapt to more precipitous landform.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
