Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the above-mentioned patents are mainly aimed at improving the reuse and firmness of the base of the high-voltage electric tower. Since the electric tower and the base are rigidly connected, when the electric tower is damaged by an earthquake When the longitudinal and transverse shock waves are impacted, the tower shakes and the bolts loosen, further causing the tower to fall

Abstract

The invention discloses an electric tower structure and a construction method thereof, and relates to the technical field of electric power construction. According to the technical main points, the electric tower structure comprises an electric tower body, mounting feet and a base, a groove is formed in the middle part of the base, a mounting plate is horizontally connected to the lower ends of the mounting feet, and a shock absorbing plate is horizontally arranged on the lower part of the mounting plate. The shock absorbing plate is provided with a plurality of first bolts which penetrate through the shock absorbing plate and the mounting plate in sequence. The first bolts are fixedly connected with the shock absorbing plate, and the first bolts are slidably connected with the mounting plate. First nuts are arranged at the ends, penetrating through the mounting plate, of the first bolts; first springs in a compressed state are connected to the positions, located on the periphery of the first bolts, between the mounting plate and the shock absorbing plate; and second springs in a natural state are arranged between the four side walls of the shock absorbing plate and the inner wallof the groove. The electric tower structure has the advantage of good seismic performance.

Description

technical field [0001] The invention relates to the technical field of electric power construction, more specifically, it relates to an electric tower structure and a construction method thereof. Background technique [0002] The electric tower is trapezoidal, triangular and other tower-shaped buildings, usually 25-40 meters high, and is a steel frame structure. Most of them are built near the power plants and distribution stations in the wild. It is an important facility in the power sector. It can protect and support overhead wires. The design, manufacture, installation, maintenance and quality inspection of power towers are important guarantees for the operation and development of modern power systems. [0003] The Chinese invention patent with the publication number CN104314354B discloses the base of a high-voltage electric tower, including a base keel. There are reinforcement piles under the platform. The high-voltage tower is connected to the base keel through the...
