Embodiment Construction

[0020] The pipe tower extraction method comprises the following steps:

[0021] a. Temporary fixing lines are set. Temporary fixing lines for temporarily fixing the pipe towers are respectively set around the pipe tower. One end of the temporary fixing line is connected to the top of the pipe tower, and the other end of the temporary fixing line is connected to the ground anchor. The included angle between the temporary fixing line and the pipe tower is 30 degrees to 60 degrees. The temporary fixing line is the line used for temporarily fixing the pipe tower. Since the temporary fixing line needs to be loosened during the extraction process of the pipe tower, The permanent fixing line is not easy to remove, so it is necessary to set up a temporary fixing line;

[0022] b. A traction line is set, one end of the traction line is connected to the top of the pipe tower through a hanging point line, and the other end of the traction line is connected to the traction equipment, and ...

Abstract

The invention relates to a power grid tension-resisting tower removing method, in particular to a pipe tower removing method. According to the pipe tower removing method provided by the invention, a toppling speed of a pipe tower is determined according to a releasing speed of a draft line during a pipe tower removing process, thus the toppling speed of the pipe tower can be conveniently adjusted through the drift line, the safety performance during pipe tower removing operation is increased, a braking effect can be obtained when the pipe tower is toppled down due to the arrangement of a braking line, and the safety performance during the pipe tower removing process is further increased; the root of the pipe tower can be located during the pipe tower removing process due to the arrangement of a herringbone derrick, and the pipe tower removing process can be more smooth and stable; the pipe tower removing method provided by the invention is suitable for various pipe towers and has the advantages that convenience in operation and high safety performance are obtained during the pipe tower removing process.

Description

technical field [0001] The invention relates to a method for removing an expansion tower of a power grid, in particular to a method for removing a pipe tower. Background technique [0002] With the rapid development of social economy, the demand for electricity is constantly increasing, the voltage level is constantly improving, and the reliability of power grid operation is also getting higher and higher, which will inevitably lead to the transformation of the original line. The work of dismantling pipe towers is gradually increasing. In the prior art, most of them use fixed pick-up rods to remove them. However, it is very difficult to operate when encountering high pipe towers, and it is easy to damage the pipe towers during the construction process. Contents of the invention [0003] The method for removing the pipe tower provided by the invention aims to overcome the disadvantages in the prior art that the pipe tower is difficult to remove and the pipe tower is easily ...
