Abstract
The invention discloses an iron tower foundation structure of a high slope overhead transmission line iron tower. The iron tower foundation structure comprises a main frame column A (1), a main frame column B (2), a main frame column C (3) and a main frame column D (4), wherein the top of the main frame column A (1), the top of the main frame column B (2), the top of the main frame column C (3) and the top of the main frame column D (4) are connected through four connecting beams (5), and two inclined columns (6) are connected to the top of the main frame column A (1) and the top of the main frame column B (2). The iron tower foundation structure has the advantages that the work amount of foundation construction is small, the security risk is low, the land resources can be protected, and the environment can be protected.
Description
Technical field
The invention belongs to overhead transmission line field of engineering technology, be specifically related to a kind of steel tower based structures of high slope iron towers of overhead power transmission lines.
Background technology
Along with the development of Chinese Urbanization, for mountain city, for improving land utilization ratio, original landform being transformed, making it trend smooth, comparatively large on the impact of physical geographic environment, easily form high slope etc.
And along with the process of urbanization, also increasing to the demand of electric load, land resources is more and more deficienter simultaneously, urban aerial power transmission line corridor passage is more becoming tight, and causes indivedual tower position to be in high slope place.This processing mode often taked has three kinds:
First kind of way, changes route scheme.This mode is because of corridor anxiety, around ancillary facility and structure more, overhead transmission line path changing certainly will not meet design requirement to the safe distance of around ancillary facility and structure, can only make cable mode into, but cable mode to increase construction investment larger;
The second way, at high slope place excavation platform.This mode causes Secondary Disturbance to original rock stratum when there is construction and excavation, and limit by the protection domain of side slope top ancillary facility and structure, the putting slope scope and can not increase of high 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, may slope failure be caused, the security of the lives and property of serious threat excavation platform place constructor and side slope top ancillary facility and structure, and larger on the impact of physical geographic environment;
The third mode, increase steel tower is differential or increase steel bracket.Increase the differential excavated volume 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 differentially 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 comparatively large and side slope is steeper, the method increasing steel bracket effectively can not solve the problem that tower is found at high slope place.
Therefore, the processing method of high slope overhead power transmission steel tower column foot, current existence foundation construction works amount is large, there is security risk, be unfavorable for problems such as protection land resources and environmental protection etc.
Summary of the invention
The object of the present invention is to provide that a kind of foundation construction engineering quantity is little, security risk is low, be beneficial to the steel tower based structures of the high slope overhead transmission line of land resources and environmental protection.
The steel tower based structures of a kind of high slope overhead transmission line of the present invention, 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 is by 4 tie-beams links, and the capital of framework principal post A and framework principal post B also chain is connected to 2 batter posts.
The steel tower based structures of above-mentioned a kind of high slope overhead transmission line, wherein: described tie-beam can be set to level or tilt.
The present invention compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: the steel tower based structures of high slope overhead transmission line provided by the present invention, because steel tower force direction is X-axis, Y-axis, Z axis three directions, with four tie-beams, four framework principal post capitals are linked, the capital displacement that the effect can offset part of horizontal power and reduce capital gene basis horizontal force produces, make framework principal post mainly bear the active force of steel tower Z-direction; The capital of 2 framework principal posts that auxiliary foundation uses two batter posts to be located on lower respectively and is positioned at eminence links, and can increase again the integral rigidity of framework; By the link of the active force of steel tower X-axis and Y direction by coupling beam and batter post; force structure is simple; make structural load transfer mode more reasonable, can reach and ensure that transmission line of electricity safety and steady runs, foundation construction engineering quantity is little, security risk is low, save construction investment and be beneficial to the object of land resources and environmental protection.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As Figure 1-5, the steel tower based structures of high slope iron towers of overhead power transmission lines of the present invention, 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 is linked by 4 tie-beams 5, and the capital of framework principal post A1 and framework principal post B2 also chain is connected to 2 batter posts 6; Wherein, described 4 tie-beams are arranged according to the maximum differential and site contour of steel tower, can make level, also can make inclination.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
