All-terrain self-balancing tower footing connecting structure

Abstract

An all-terrain self-balancing tower footing connecting structure comprises four tower legs and connecting foundations. The four tower legs are connected with the connecting foundations through connecting tower foot plates correspondingly. The four tower legs are connected through steel I-beams in a cross beam manner. The connecting foundations are arranged in at least one layer. Each connecting tower foot plate comprises a tower foot bottom plate and a tower foot side plate. Each tower foot and one end of the corresponding connecting foundation are in contact with each other through the corresponding tower foot bottom plate and are fixed through a foundation bolt. The all-terrain self-balancing tower footing connecting structure has the beneficial effects that all-terrain tower footing self-balancing and omnidirectional connection is achieved through the connecting structure of the connecting foundations; and on one hand, the foundation work amount and the tower footing earthwork amount can be effectively reduced, and on the other hand, the integral rigidity of the upper structure can be improved, and the horizontal load of the upper structure can be resisted effectively.

Description

technical field [0001] The invention relates to the field of power transmission line towers, in particular to an all-terrain self-balancing tower foundation connection structure. Background technique [0002] With the development of my country's economy, society and power grid construction, transmission lines need to be erected in mountainous areas according to the terrain, geological and natural environment and other conditions. Due to the complex conditions of the line corridors in mountainous areas, tower foundations are generally located on bases of unequal heights. At present, the commonly used treatment methods total 3 types: the first type uses the descending square to make the four tower legs of each base tower at the same base level; the second type uses the foundation column to lift to the same base level; the third type adopts the scheme of "long and short legs + high and low columns" . The first option needs to excavate the mountain body of the four tower legs acc...

AI Technical Summary

Problems solved by technology

The first option needs to excavate the mountain body of the four tower legs according to the elevation of the central pile. The amount of the project is generally very large. At the same time, this method will cause serious damage to the mountain body and vegetation, which will be unfavorable to the stability of the tower foundation. At the same time, it does not meet the requirements of environmental protection; the second scheme keeps the base surface consistent by raising the foundation. Due to the high outcrop, the effective buried depth of the foundation needs to be increased, so the final foundation engineering volume is relatively large

The third option is only applicable to angle steel towers equipped with high and low legs, not applicable to flat leg angle steel towers with voltage levels of 110kV and below
