Assembly type overhead construction process

Abstract

The invention provides an overhead construction process, which comprises the following steps of measuring data and calculating the wire length, wherein field data and the influencing quantity of the pressure welding length of a strain clamp are collected and the length of a strain insulator-string is measured; and calculating the wire length according to a formula, wherein L is the wire length; H is the conductor tension; omega is the weight of the conductor per unit length; l is the horizontal distance between the hanging points of the conductor; h is the altitude difference between the hanging points of the conductor; performing fixed-length manufacturing and machining wires, wherein the length of each conductor is calculated according to a wire length calculation formula, the conductor allocation is performed based on the control of the longest conductor of each phase, and the length of the conductor of each coil to be machined is determined; releasing the wires; and tightly hanging the wires. In the overhead construction process, the length of the required wire of each span can be measured directly on the ground, the installation position of a suspension clamp is demarcated, and thus the wires are suspended to achieve the preset completion sag without wire sag observation. Meanwhile, the overhead construction process and the quality level are improved, while the construction quality and the safety are ensured.

Description

【Technical field】 [0001] The invention relates to a construction technique for erecting power transmission and transformation lines. 【Background technique】 [0002] In the current stringing construction technology of power transmission and transformation lines, the length of the wires in the stringing construction section is only completed by rough calculation. Such a rough estimate often leads to large errors, which need to be eliminated by increasing the construction process. On the one hand, the project cost is increased, and on the other hand, construction safety risks, hidden dangers of construction quality, and construction period are prolonged. Obviously, such a construction technique cannot meet the high requirements of the industry for the stringing construction technique. 【Content of invention】 [0003] In view of this, it is necessary to provide a precisely controlled stringing construction process. [0004] A construction technique for stringing wires, compri...
