Description

Technical Field

[0001] The present invention relates to the technical field of spiral ground piles, in particular to a spiral ground pile for a transmission tower and a processing technology thereof. Background Art

[0002] The transmission tower is the support point of the overhead line. If one circuit is installed on the transmission tower, it is a single-circuit transmission tower. If two circuits are installed on the transmission tower, it is a double-circuit transmission tower. During the installation of the transmission tower, spiral piles are used to increase the stability of the bottom of the transmission tower and are mostly used in high-latitude cold areas.

[0003] A Chinese patent discloses a spiral ground pile (authorization announcement number CN209040120U). The patented technology includes a plastic outer rod with a cavity along its axial direction and a metal inner rod embedded in the cavity to strengthen the structural strength of the plastic outer rod. The metal inner rod is pressed against the inner wall of the cavity and one end of the metal inner rod passes through the plastic outer rod. The outer wall of the plastic outer rod is provided with a spiral piece and the end of the plastic outer rod away from the metal inner rod is conical to form a tip. The metal inner rod gives the ground pile better structural strength, so that the ground pile can bear greater force, while the plastic outer rod The rod reduces the weight of a ground pile of the same volume, making it easier to transport the pile. The plastic outer rod is more corrosion-resistant than metal, extending the service life of the pile. However, the spiral ground pile is made of metal both inside and outside, making the device heavy, inconvenient to carry, and expensive. The paint used for rust prevention is spray-painted, but the paint has poor adhesion and easily corrodes and falls off after prolonged exposure to soil, causing the device to rust rapidly, which is detrimental to the support effect. The lack of an anti-detachment structure means the spiral ground pile easily detaches after being fixed, which is detrimental to support stability. Therefore, those skilled in the art provide a transmission tower spiral ground pile and a processing technology to address the problems raised in the above-mentioned background technology.
