Adaptive earth anchor

Adaptive earth anchor:

The utility model relates to the technical field of ground earth anchor, in particular to an adaptive ground earth anchor. In the process of construction of high-voltage transmission lines, the geographical conditions are often changeable. When the geological conditions such as sandy land, soft soil and clay are encountered, the traditional ground anchor cannot meet the requirements of safe construction. When the traditional anchor is used, it is necessary to dig the anchor pit first, and then bury the anchor in the ground. The construction excavation is large and the labor intensity is high. Moreover, after completion of construction, it is difficult to recover ground anchor, resulting in low efficiency and high construction cost. On the other hand, the traditional anchor is a solid cylinder, which makes the anchor bulky and inconvenient for the secondary transfer between mountains. The utility model provides an adaptive ground anchor which is scientific in structure, light in weight, superior in mechanical performance, practical and convenient.  The utility model adopts the technical scheme of an adaptive ground earth anchor, which comprises an anchor tip, an anchor body and an anchor blade push shaft; The anchor body is a double-layer hollow cylinder structure; The anchor tip is fixedly arranged at the lower end of the anchor body; The anchor blade push shaft is glibly arranged in the inner cylinder of the anchor body, and the lower end is hinged with at least one group of extendable anchor blades; Each group of anchor blades has three blades, and the anchor body is provided with window holes corresponding to the blades for the expansion of the anchor blades; The upper part of the anchor blade pushing shaft is also provided with a steel column; The diameter of the steel column is smaller than the inner cylinder of the anchor body, and the upper end is beyond the upper surface of the anchor body.  As an optimization, window holes in the same horizontal plane on the anchor body are evenly distributed on the anchor body.  As an optimization, the anchor blade has two groups, and corresponding window holes are arranged in two layers, and staggered between the upper and lower layers of window holes.  As an optimal choice, three pull rings are fixed on the upper outer surface of the anchor body; The pull ring is fastened to the earth anchor.
