Construction method of power transmission line steel tube tower

Abstract

The invention discloses a construction method of a power transmission line steel tube tower. The method is characterized by including: selecting materials; manufacturing the steel tube tower, to be more specific, welding the selected materials into a set steel tube tower structure; performing weld inspection, to be more specific, placing a probe, connected with an ultrasonic detecting device, at the lateral end of a steel pipe with a butt-joint weld, allowing the probe to be matched with the outer diameter of the steel pipe, transmitting ultrasonic waves by the probe to cover the whole butt-joint weld when the ultrasonic detecting device transmits signals, and performing creeping wave testing to analyze the defects of the butt-joint weld; mounting the steel tube tower, to be more specific, using a line lifter to lift the main line of the steel tube tower to the mounting point of a suspension clamp after the power transmission line steel tube tower is erected, fixing the main line, removing the line lifter, connecting the branch line cross arm of the steel tube tower with a branch line through a strain clamp, and connecting and communicating the branch line of the steel tube tower with the main line of the steel tube tower through a connecting line.

Description

technical field [0001] The invention relates to a construction method of a steel pipe tower of a power transmission line. Background technique [0002] Existing conventional steel pipe towers for power transmission lines are composed of steel pipe tower trunks and several branch line cross-arms arranged on the trunk. To implement the connection between the branch line and the main line, the general specific implementation steps are as follows: 1. The two main trunks at the front and rear should first anchor the wires, which need to be clamped with 15 Φ16 steel wire ropes, and the wires should be anchored on the ground anchor; 2. The motorized winch pulls the wire, then breaks the wire, and loosens it to the ground; 3. Make hydraulic connection tension clamp; 4. Tighten the wire, hang the wire, remove the anchor wire and steel wire rope of the front and rear two base dry towers; 5. Make jumper connection The required manpower and material resources are roughly as follows: 16...

Problems solved by technology

Under the premise that a crane can be used to erect steel pipe towers, such power outage construction generally takes about 8 hours. In the current environment where reliability requirements for power transmission and transformation are increasing, it will have a great impact on reliability data

[0003] Invention patent application No. 201010564105.1 also discloses a construction method, but it is relatively simple and does not provide effective detection and material selection steps, which cannot make the construction progress smoothly.
