Core penetrating assembled foundation for power transmission line

Abstract

The invention relates to a core penetrating assembled foundation for a power transmission line. The core penetrating assembled foundation comprises a beam, a stand column connected with the upper surface of the beam and PHC pipe piles penetrating through the beam in the width direction of the beam. The top end of the stand column is connected with an iron tower leg through a cross-shaped insertingleg. The beam is a prefabricated concrete beam. The multiple PHC pipe piles are evenly arranged in the length direction of the beam. The PHC pipe piles are used for replacing an original bottom plateto serve as stress components, the PHC pipe piles are used for penetrating through the beam to form a core penetrating structure, and the problem that field installing and positioning are difficult is solved; and meanwhile, building block type detachment is adopted in the beam, the weight of the single components is reduced, and transportation and field installation are convenient.

Description

technical field [0001] The invention relates to the field of power transmission line engineering, in particular to a core-through assembled foundation for power transmission lines. Background technique [0002] In deserts, Gobi, permafrost and other sparsely populated, high-cold and high-altitude areas such as deserts, Gobi, and permafrost, where it is difficult to make concrete on site or the construction conditions are poor, the effective construction period is short, and the construction efficiency is very low, as well as in areas damaged by disasters. In the construction of foundation projects for quick repair of power transmission lines, if the transportation conditions are acceptable, the prefabricated foundation type should be considered first. [0003] The prefabricated foundation of transmission lines is generally a tower foundation assembled on-site by multiple metal components or prefabricated concrete components through connectors, and a combination of metal comp...

AI Technical Summary

Problems solved by technology

The traditional prefabricated concrete prefabricated foundation is not conducive to the hoisting and installation at the construction site due to the excessive weight of the individual components, and the installation is very difficult; the prefabricated steel prefabricated foundation or the prefabricated concrete lath The upper angle steel support is obliquely inserted into the soil of the foundation pit. On the one hand, there are many components that are difficult to assemble on site. On the other hand, the construction quality of the backfill soil density of the foundation pit cannot be guaranteed, and there are great safety hazards.
