Abstract

The invention relates to a reverse folding type ground anchor of a power transmission line. The reverse folding type ground anchor is characterized by comprising a left side ground anchor, a right side ground anchor and a middle ground anchor group, wherein the upper ends of the left side ground anchor, the middle ground anchor group and the right side ground anchor are sequentially connected through a folding rotating shaft; a ground anchor lifting ring is arranged at the end part of the left side ground anchor or the right side ground anchor; and a ground anchor stress ring is arranged in the middle of the middle ground anchor group. The reverse folding type ground anchor is scientific and reasonable in design, adopts a hollow design of steel plate welding, is light in size, convenient to carry and convenient to lift, can avoid the phenomena of large labor amount, high safety risk and anchor abandoning of manual anchor digging, and improves the safety and the economy of construction.

Description

technical field [0001] The invention belongs to the construction field of high-voltage power transmission lines for power transmission, and relates to ground anchors, in particular to a reverse-folding ground anchor for power transmission lines. Background technique [0002] In the construction of transmission lines, based on the influence of severe sandy areas on the ground anchorage bearing oblique tension, it is necessary to use group anchors and require a large depth of burial in order to increase the sufficient uplift force of the ground anchors. Small excavators are generally used for ground anchor burial , Most of the anchor work is manually excavated, and the buried depth is generally 2.5 to 3.2 meters. There are cases where anchors are abandoned or lost due to difficulties in lifting anchors, and abandoned ground anchors also affect environmental protection and increase project costs. [0003] In view of the above situation, it is very necessary to design a ground ...
