Problems solved by technology

[0003] In the erection construction of large-span lines, the initial guide rope is usually used to select the method of unmanned aerial vehicle to deploy the initial guide rope. Through step-by-step traction, the initial guide rope → guide rope (multi-level) → traction rope is completed, and vertical and horizontal shifts are implemented. , to complete the deployment of each phase of the traction rope, but this method has cumbersome construction procedures, a large amount of high-altitude operations, and the harsh climate at sea, which poses a high safety risk

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0020] A construction method for pulling and pulling Dyneema across the sea without falling into the water, comprising the following steps:

[0021] Install the No. 1 anchor tower and several spanning towers on the coast, and install the traction field and high-span anchor towers on the opposite bank;

[0022] The No. 1 rope is deployed from the No. 1 anchor tower to several No. 2 spanning towers, and then the No. 1 rope is deployed to the coast through several No. 2 spanning towers;

[0023] One end of the No. 3 rope is fixed on the traction field, and the No. 3 rope on the opposite bank is deployed from the traction field to the high-span anchor tower, and then the No. 3 rope is extended to t...

Abstract

The invention discloses a transmission line cross-sea over-water Dyneema traction construction method. The method is characterized by comprising the steps that a first anchor tower and a plurality ofcrossing towers are installed on the coast, and a traction field and a high-span anchor tower are installed on the opposite coast; a first rope is unfolded from the first anchor tower to a plurality of second crossing towers, and then the first rope is unfolded to the coast through the plurality of second crossing towers; one end of a third rope is fixed to the traction field, the third rope on the opposite coast is unfolded from the traction field to the high-span anchor tower, and then the third rope extends to the side of the opposite coast; the first rope is connected with one end of a wear-resistant second rope, the other end of the second rope is fixed to a tractor tug, and then the tractor tug carries the other end of the second rope to the opposite coast; and the other end of the second rope and the other end of the third rope are in butt joint for lift-off. The method can be widely applied to transmission line cross-sea leading rope unfolding construction, is simple in procedure, safe and reliable, and greatly improves the working efficiency of construction.

Description

technical field [0001] The invention relates to a dyneema construction method for a transmission line crossing the sea without falling into the water, and belongs to the technical field of high-voltage transmission power supply. Background technique [0002] With the rapid development of the national economy, the advancement of science and technology, and the increasing demand for environmental protection, the power industry, as a pillar industry for economic construction and people's lives, is undergoing tremendous changes. The development of high-voltage and ultra-high-voltage transmission has become the main development mode of power supply in various countries. The Zhoushan 500 kV interconnection project is an important power transmission and transformation project recently constructed by the State Grid Zhejiang Electric Power Company. Improve the Zhoushan island energy security system to meet the delivery needs of Zhoushan energy base; improve the ability of Zhoushan po...
