Abstract
The utility model discloses a high slope overhead transmission line's iron tower base structure, including frame principal post A (1), frame principal post B (2), frame principal post C (3) and frame principal post D (4), frame principal post A (1), frame principal post B (2), frame principal post C (3) and frame principal post D's (4) capital is linked through 4 tie -beam (5), and 2 batter post (6) have still been linked to frame principal post A (1) and frame principal post B's (2) capital. It hangs down, does benefit to the characteristics of land resource and environmental protection to have little, the safe risk of basic construction work volume.
Description
Technical field
The utility model belongs to overhead transmission line field of engineering technology, is specifically related to the steel tower based structures of a kind of high side slope iron towers of overhead power transmission lines.
Background technology
Along with the development of Chinese Urbanization, for city, mountain area, for improving land utilization ratio, original landform is transformed, make it trend smooth, the impact of physical geographic environment is bigger, it is easy to form high side slope etc.
And the process along with urbanization, the demand of electric power load is also increasing, and land resources is more and more deficienter simultaneously, and urban aerial power transmission line corridor passage is more becoming tight, and causes indivedual tower position to be in high side slope place. This processing mode often taked has three kinds:
First kind of way, changes route scheme. This kind of mode is because of corridor anxiety, around affiliated facility and structures are more, the safe distance of affiliated facility around and structures certainly will do not met design requirement by overhead transmission line path changing, can only make cable mode into, but cable mode increase construction investment is bigger;
2nd kind of mode, excavates platform at high side slope place. When this kind of mode exists construction and excavation, original rock stratum is caused two disturbances, and limit by the protection domain of side slope top affiliated facility and structures, the putting slope scope and can not increase of high side slope, for meeting vertical tower condition, cause the more former side slope of the gradient steeper (being tending towards 90 degree), during construction and excavation, it is possible to cause side slope to be caved in, the security of the lives and property of serious threat excavation platform place workmen and side slope top affiliated facility and structures, and the impact of physical geographic environment is bigger;
The third mode, increase steel tower is differential or increases Steel Bracket. Increase the differential excavation amount reducing chain-wales of steel tower, but steel tower is differential can not infinitely be increased, it is general when the gradient reaches more than 40 degree, steel tower is maximum differential cannot be regulated, and the method increasing Steel Bracket can only be used for the tower position that basis dew is high and horizontal force basic role power is less, when basic role power is relatively big and side slope is steeper, the method increasing Steel Bracket can not effectively solve the problem of the vertical tower in high side slope place.
Therefore, the treatment process of high side slope overhead power transmission steel tower tower base, current existence foundation construction work amount is big, there is security risk, be unfavorable for the protection problems such as land resources and environment protection.
Summary of the invention
The purpose of this utility model is to provide that a kind of foundation construction engineering amount is little, security risk is low, be beneficial to land resources and the steel tower based structures of the high side slope overhead transmission line of environment protection.
The steel tower based structures of a kind of high side slope overhead transmission line of the present utility model, comprise framework principal post A, framework principal post B, framework principal post C and framework principal post D, the capital of described framework principal post A, framework principal post B, framework principal post C and framework principal post D by 4 connect beams link, the capital of framework principal post A and framework principal post B also chain be connected to 2 batter posts.
The steel tower based structures of above-mentioned a kind of high side slope overhead transmission line, wherein: described connection beam can be set to level or tilt.
The utility model is compared with prior art, there is obvious useful effect, as can be known from the above technical solutions: the steel tower based structures of high side slope overhead transmission line provided by the utility model, because steel tower force direction is X-axis, Y-axis, Z axle three directions, connect beam with four to be linked by four framework principal post capitals, part of horizontal power can be offset and reduce the capital displacement that capital produces because of the effect of basal level power, make framework principal post mainly bear the reactive force of steel tower Z direction of principal axis; Auxiliary basis uses two batter posts to be located on lower respectively and be positioned at the capital link of 2 framework principal posts of eminence, can increase again the integral rigidity of framework; By the reactive force in steel tower X-axis and Y-axis direction by the link of coupling beam and batter post; force structure is simple; make structural load transfer mode more reasonable, can reach and ensure that transmitting line safety and steady runs, foundation construction engineering amount is little, security risk is low, save construction investment and be beneficial to the object of land resources and environment protection.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As Figure 1-5, the steel tower based structures of high side slope iron towers of overhead power transmission lines of the present utility model, comprise framework principal post A1, framework principal post B2, framework principal post C3 and framework principal post D4, the capital of described framework principal post A1, framework principal post B2, framework principal post C3 and framework principal post D4 by 4 connect beams 5 link, the capital of framework principal post A1 and framework principal post B2 also chain be connected to 2 batter posts 6; Wherein, described 4 connect beams and arrange according to the maximum differential and site contour of steel tower, can make level, it is possible to make inclination.
The above, it it is only better embodiment of the present utility model, not the utility model is done any restriction in form, any do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belongs in the scope of technical solutions of the utility model.
