Anti-rotation angle tower frame foundation and manufacturing method

Abstract

The invention provides a steeliness anti-rotation angle tower frame foundation and a manufacturing method. The structure consists of a tower frame installation flange plate, a triangular cylinder foundation pile and an anti-rotation wing element; the tower frame installation flange plate is welded at the top end of the triangular cylinder foundation pile, the anti-rotation wing element is arranged at the vertical side part of the triangular cylinder foundation pile, the top end of the anti-rotation wing element is welded with the bottom of the tower frame installation flange plate, and the top part of the triangular cylinder foundation pile and the connection turning part of the tower frame installation flange plate are welded with stiffened plates. Compared with the prior art, the steeliness anti-rotation angle tower frame foundation overcomes the defects of the rotation of the round tube type rotation angle tower caused by uneven stresses when bracing wire as well as the long construction time and high construction cost when casting the rotation angle tower foundation. The invention has the advantages of simple structure, scientific design, easy construction, strong adaptability and the like, can be installed and used by piling in-situ without the need of evacuating further, is not limited to terrain and has no influence on nearby buildings, thereby having good promotion and application values.

Description

technical field [0001] The invention relates to a foundation technology for a steel pipe pole corner tower of a high-voltage power transmission and transformation line, in particular to a novel steel anti-rotation corner tower foundation. Background technique [0002] From the analysis of the stress on the foundation of the corner tower, the foundation of the power corner tower has long been subjected to vertical loads such as the weight of the tower body and accessories (guide line, cross arm, insulator, fittings) and horizontal loads such as wind force or wire tension. In addition, there are some temporary and additional but crucial external forces, such as the installation load of the hanging wire, hanging wire, anchor wire and tightening wire in the construction of the pole tower, the weight of the installation worker, the weight of tools and other installation additional loads. The sudden unbalanced tension and the resulting torque and shear force when pulling the wire ...

AI Technical Summary

Problems solved by technology

This method can effectively prevent the possibility of rotation of the corner pole tower due to uneven force during the wire pulling process, but this method takes a long time and has high construction costs; the piling of the steel pipe pole foundation is fast, convenient and safe, but the existing The cylindrical foundation of the corner pole tower may rotate due to uneven force during the pulling process, so this technology cannot be used on the corner tower foundation
