The invention discloses an installation construction method of an overhead power transmission line power tower, and relates to the technical field of power transmission. The installation constructionmethod of the overhead power transmission line power tower is completed by an installation construction device of the overhead power transmission line power tower. The installation construction deviceof the overhead power transmission line power tower comprises a walking trolley, a foundation pit and an abutting leg, wherein the foundation pit is a trough pit excavated in the ground, an opening of the foundation pit faces upwards, an inclination surface is arranged at an opening position of the top end of the foundation pit, the root of the power tower is arranged on the opening of the foundation pit, and the abutting leg is arranged at a position near to the opening position of the foundation pit. The foundation pit used for fixing the power tower is excavated in the ground, the openingof the foundation pit faces upwards, the root of the whole power tower is buried in the foundation pit, so that the power tower is vertically fixed at the ground, the situations that a plurality of connection points are generated when the power tower is buried in the ground and the power tower is broken due to stress concentration are prevented, and the installation firmness of the power tower isimproved.
Description
technical field [0001] The invention relates to the technical field of power transmission, in particular to a method for installing and constructing power poles and towers of overhead power transmission lines. Background technique [0002] The power pole tower is a kind of transmission line pole tower. The power pole tower is a tower structure used to support and overhead wires, lightning protection wires and other accessories, so that the wires and wires, wires and towers, wires and lightning wires, wires to the ground or cross A towering structure that maintains a prescribed safety distance from overhanging objects. [0003] Existing patent No. CN201910589329.9 discloses a power pole and tower installation base and installation method suitable for mountainous terrain. The base includes a base body and several fixing rods. The bottom of the base body is provided with the number of fixing rods For the same threaded holes, one end of the fixed rod is provided with a threaded...
