Problems solved by technology

However, the conventional straightening of the iron tower only replaces part of the force of the foundation by pulling the cable. After the cable is loose, the force of the tower will deteriorate, and the effect of righting is not ideal.

Abstract

The invention provides an iron tower capable of coping with uneven settlement in a mining area and a straightening method thereof. The iron tower includes a tower body, a tower foot and a foundation, and the lower end of the tower foot is connected to the foundation through a shoe plate; the tower foot The upper end is provided with two connecting ears parallel to each other, and a row of uniform connecting holes is provided on the connecting ears, and the joint between the tower body and the tower foot is provided with a Matching slots, the thickness of the tower body on the outside of the slot is equal to the distance between the two connecting ears, and the tower body on the outside of the slot is provided with through holes that match the connecting holes and are smaller in number than the connecting holes; A level sensor is provided on the crossbeam of the tower body; a spatial coordinate locator is respectively provided on the tower foot; One end is wound on the bobbin on the body of the tower. It is especially suitable for use in areas with uneven settlement, and the straightening after settlement is simple and reliable.

Description

technical field [0001] The invention relates to the construction field of straightening iron towers, in particular to an iron tower capable of coping with uneven settlement in mining areas and a straightening method thereof. 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 when the ...
