Problems solved by technology

However, the conventional iron tower righting only replaces part of the force of the foundation by pulling wires, and the stress on the tower will deteriorate after the wires are loose. There is no reasonable method to support the data calculation in the tower righting, resulting in poor righting effect satisfactory

Embodiment 1

[0041] like Figure 1 to Figure 3 As shown, the present invention provides a kind of steel tower uprighting calculation method dealing with the uneven settlement of mining area, and described method comprises the following steps:

[0042] (1) Determine the tower foot with the most significant settlement and its settlement displacement according to the reference point;

[0043] (2) Determine the length ΔL that the main material of the tower foot needs to increase according to the settlement displacement and the tower body slope angle θ;

[0044] (3) Determine the displacement data of the shoe plate of the tower foot according to the length ΔL that needs to be increased by the main material of the tower foot and the root opening data.

[0045] The selection of the reference point may include:

[0046] Choose the tower foot with the highest height as the reference point.

[0047] The selection of the tower foot with the most significant settlement may include:

[0048] The to...

Embodiment 2

[0069] Based on the same inventive concept, the present invention also provides a tower straightening calculation device for dealing with uneven settlement in the mining area, said device comprising:

[0070] The first determination module is used to determine the tower foot with the most significant settlement and its settlement displacement according to the reference point;

[0071] The second determination module is used to determine the length of the main material of the tower foot to be increased according to the settlement displacement and the slope angle of the tower body;

[0072] The third determination module is used to determine the displacement data of the tower foot shoe plate according to the length of the tower foot main material that needs to be increased and the root opening data.

[0073] The selection of the reference point may include:

[0074] Choose the tower foot with the highest height as the reference point.

[0075] The selection of the tower foot w...

Abstract

The invention provides a method and a device for calculating the righting of an iron tower for dealing with uneven settlement of a mining area. The method includes the following steps: (1) determining the tower foot with the most significant settlement and its settlement displacement according to a reference point; (2) Determine the length of the main material of the tower foot to be increased according to the settlement displacement and the gradient angle of the tower body; (3) Determine the displacement data of the shoe plate of the tower foot according to the required increase of the length of the main material of the tower foot and the root opening data. The calculation of this method is clear and the data is reasonable, which can provide reliable data support for the tower righting, and provide a righting strategy of increasing the main material and replacing the shoe plate for the tower righting, avoiding the overall replacement of the iron tower and saving costs; Large secondary stress is generated in the main material and inclined material at the foot of the tower, which ensures the quality of the tower after righting.

Description

technical field [0001] The invention relates to an auxiliary process for straightening an iron tower, in particular to a calculation method and device for straightening an iron tower to cope with uneven settlement in a mining area. Background technique [0002] In my country's Shanxi, Anhui and other coal producing areas, the mining areas formed by coal mining are widely distributed. Under the influence of the uneven subsidence of the ground surface, the transmission lines and transmission towers passing through the mining area have more tower collapse accidents or early scrapping, resulting in more economic and property losses. If the tower with foundation settlement is not corrected, its force will be very unfavorable, and a tower collapse accident will occur sooner or later, and the cost of scrapping it in advance to build a new tower is also very high. Therefore, by straightening the tower, the stress state of the tower can be improved, and a new tower can be avoided wh...
