Problems solved by technology

[0002] The vertical layout of the 220kV power distribution equipment site adopts a vertical and horizontal two-way single slope with a slope of 5‰, and the height difference between the highest point and the lowest point of the site is about 2.5m, which brings great difficulties to the foundation design of the 220kV frame structure
[0003] The foundation of the conventional frame structure is generally buried at the same elevation, the length of the frame columns is the same, and the bottom of the beam is horizontal. Insufficient, which leads to safety hazards

Embodiment 1

[0028] like Figure 1-Figure 4 As shown, in this embodiment, a 220kV frame structure suitable for sites with relatively large slopes is specifically provided, including several frame columns 1. In this site, each frame column 1 is arranged in a horizontal and vertical manner, and each The bottom ends of the frame columns 1 are buried in the site at the same depth, and the embedment depths of each frame column 1 are the same. If the site is simulated as a standard slope, the vertical distance between the top of each frame column 1 and the surface of the site is Equal spacing can also be understood as the apex of each frame column 1 is connected to form a "surface", and the "surface" should be parallel to the slope of the site.

[0029] At least one frame beam 2 is arranged between two adjacent frame columns 1, and the number of frame beams 2 is the 220Kv layout site requirements, depending on the actual situation; the two ends of the frame beam 2 pass through The leveling supp...

Embodiment 2

[0034] like Figure 5 , Image 6 As shown, in the technical solution disclosed in Embodiment 1, since the embedment depth of each frame column 1 relative to the site is the same, it is necessary to ensure that the distance between two adjacent frame columns 1 is equal along the slope direction of the site, so as to be able to The common use of the actual leveling support, otherwise, when the distance between two adjacent frame columns 1 changes, the corresponding required leveling height will also be different, resulting in the leveling support cannot be used universally, and in the construction process on site In some cases, the actual demand for leveling cannot be met. In this embodiment, the following structure is used to design the leveling support, as follows:

[0035]The leveling support also includes a bearing body 10, the bearing body 5 is slid on the bearing body 10 along the direction of gravity, and a rhombus jack 11 is arranged between the bearing body 10 and the ...

Abstract

The invention discloses a 220kV framework structure suitable for a large slope site, and belongs to the technical field of extra-high voltage alternating current transmission of electric power engineering. The 220kV framework structure comprises a plurality of framework columns, wherein the bottom ends of the framework columns are buried at the same depth relative to the surface of the site, at least one framework beam is arranged between every two adjacent framework columns, the two ends of each framework beam are assembled on the two corresponding adjacent framework columns through levelingsupports, the framework beams are in a horizontal state to meet the requirements of electrical wiring and can be adjusted according to different site slopes, and the 220kV framework structure has goodeconomic benefits.

Description

technical field [0001] The invention belongs to the technical field of ultra-high voltage AC power transmission in electric power engineering, and relates to the professional frame technology of civil engineering structures, in particular, to a 220kV frame structure suitable for large slope sites. Background technique [0002] The vertical layout of the 220kV power distribution device site adopts a vertical and horizontal two-way single slope with a slope of 5‰, and the height difference between the highest point and the lowest point of the site is about 2.5m, which brings great difficulties to the foundation design of the 220kV frame structure. [0003] The foundation of the conventional frame structure is generally buried at the same elevation, the length of the frame columns is the same, and the bottom of the beam is horizontal. Insufficient, and then lead to security risks. Contents of the invention [0004] In view of this, in order to solve the above-mentioned probl...
