Embodiment

[0016] like Figure 1-Figure 3 Shown is a small-load sleeve-type foundation structure in mountainous areas, including a sleeve column body 1 embedded below the ground and a lower expansion bottom 3 integrated with the sleeve column body. The lower expansion bottom is located at the bottom of the sleeve column body The lower end, the overall orthographic projection surface of the bottom expansion bottom is a circular structure, the upper end diameter of the bottom expansion bottom is smaller than the bottom diameter, and the sleeve column body is provided with a hole 4 for power supply rod insertion, and the hole groove is a blind hole. A plurality of oblique anchor rods 2 are distributed in a circular array around the column body, and the oblique anchor rods have a structure of upper and lower layers. Each layer has at least three, and the angle between the inclined anchor rod and the column body is any value between 30-60 degrees. One end of the inclined anchor rod is connect...

Abstract

The invention relates to the field of transmission line tower foundations, and provides a mountainous area small-load sleeve type foundation structure in order to overcome the defects of an existing transmission line tower foundation on the aspects of mountainous area transportation and economy. The mountainous area small-load sleeve type foundation structure comprises a sleeve pillar body pre-embedded under the ground and a lower expanded base forming an integrated structure with the sleeve pillar body. The lower expanded base is located at the lower end of the sleeve pillar body, the orthographic projection surface of the whole lower expanded base is of a round structure, and the diameter of the upper end of the lower expanded base is smaller than that of the lower end of the lower expanded base. The sleeve pillar body is internally provided with a hole groove where a power pole can be inserted. The design of an inclined anchor rod can improve the anti-overturning stability of the power pole foundation, and the base is designed in the form that the diameter of the upper end of the base is smaller than that of the lower end of the base, so that the base improves the anti-overturning stability of the power pole foundation and effectively improves anti-pulling capacity, and the base is suitable for the mountainous area small-load sleeve type foundation structure.

Description

technical field [0001] The invention belongs to the field of transmission line tower foundations, in particular to a small-load sleeve-type foundation structure in mountainous areas. Background technique [0002] With the development of my country's economic society and power grid construction, the conditions of line corridors are becoming more and more complex. In mountainous areas, it is necessary to adopt new technical solutions for tower foundation engineering on slopes and to choose high outcropping foundations in accordance with the conditions of the terrain, geology and natural environment. The foundation of cement poles for 10kV overhead lines mainly includes direct buried foundation, chassis + chuck foundation, sleeve foundation and stepped foundation. However, for the cement poles of 10kV lines in mountainous areas, especially the corner cement poles with large root bending moments, in order to ensure the stability of the foundation, a certain range of stable slope...
