Embodiment Construction
[0023] The operation path perpendicular to the direction of the slope is the same as that of the road perpendicular to the slope direction of the site in order not to block the discharge of rainwater and cause the site to accumulate water, so that rainwater can smoothly pass through the operation path along the direction of the slope.
[0024] The slope-type vertical layout method is adopted. In order to keep the 110kV and 220kV power distribution devices horizontal along the direction of the busbar, the tops of each frame column are on the same horizontal plane. The requirements are met by selecting different lengths of frame columns to adapt to the change of the site slope (see image 3 ), that is, the length of the frame column should be shorter at the high point of the slope, and longer at the low point of the slope, so that the top of the frame column is at the same level.
[0025] The site for the 110kV power distribution device has a large slope. In order to prevent the ...

Disclosed is a 220 kV transformer substation slope-type vertical arrangement method. The method comprises the steps that the physical terrain of a mountain slope is utilized, vertical design is carried out to conform to the physical terrain, various devices and buildings are arranged according to the physical terrain of the mountain slope, excavation and filling are carried out on earthwork of a site to achieve natural balance, and no large-area range earthwork flattening is carried out; an operating path and an operating terrace are formed on a road perpendicular to the slope direction of the site in the direction perpendicular to the slope; an urban type road is designed at the higher position of the slope in the road perpendicular to the slope direction of the site, and kerbstone is arranged; a highway type road is designed at the lower position of the slope; according to the operating path, the urban type road is designed at the higher position of the slope, and the kerbstone is arranged; the highway type road is designed at the lower position of the slope. By using the 220 kV transformer substation slope-type vertical arrangement method, no large-area range earthwork flattening needs to be carried out; on the premise of achieving natural balance through excavation and filling of the earthwork of the site, the height of a retaining wall is reduced, the earthwork quantity is reduced, foundation treatment is facilitated, the number of wall outer protective slopes and the floor space are reduced, meanwhile, the original station location appearance is maintained to the maximum extent, and environment is protected.
Description
technical field [0001] The invention relates to a slope-type vertical arrangement method of a 220kV substation conforming to the natural terrain, arranging various equipment and buildings according to the situation on the mountain, and not performing large-scale earthwork leveling. Background technique [0002] The vertical design of the substation generally adopts a flat slope or a stepped layout, and the station area needs to be leveled before the buildings and electrical equipment are arranged. As for the hilly landform, when designed according to the conventional vertical method, the damage to the mountain body will be greater, which will affect the stability of the mountain body, and will cause greater damage to the water and soil conservation, and will have an impact on the environment. Moreover, for the substations arranged in the existing way, the drainage performance is poor, and it is easy to cause water accumulation on the site. [0003] With the release of the ...
