Description
Technical Field
The utility model relates to a high voltage transmission tower technical field that rectifies, more specifically relates to a self-supporting iron tower seat deviation correcting device.
Background
The foundation settlement refers to the foundation surface subsidence caused by the foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, can cause buildings above the foundation or the power transmission iron tower to incline, and the foundation already has self-weight stress caused by the self gravity of the soil body. The load of the power transmission iron tower on the foundation is transmitted to the foundation through the bottom surface of the foundation or the embankment, so that the original stress state of the natural soil layer is changed, and under the action of an additional three-dimensional stress component, vertical, lateral and shearing deformation is generated in the foundation, and vertical and lateral displacement of each point is caused. Vertical deformation of the foundation surface is referred to as foundation settlement, or foundation settlement. Due to differences in the load of objects on the foundation, unevenness of the foundation and the like, the settlement of each part of the foundation is always uneven, so that additional stress and deformation are generated in the upper structure or the pavement structure, corresponding to the ground surface. Uneven settlement of the foundation beyond a certain limit can cause cracking, tilting and even damage of buildings or facilities above the foundation, such as cracks of brick walls, clamping or sliding rails of crane wheels, tilting of high-rise buildings, deflection of machine rotating shafts, breakage of connecting pipes with the buildings, deviation of bridges from piers, cracking of beam surfaces or road surfaces, and the like. Once the foundation of the power transmission iron tower is settled to cause the power transmission iron tower to incline, the power transmission of the inclined power transmission line of the power transmission iron tower is interrupted if the foundation of the power transmission iron tower is slightly settled, and the life and property safety of passing pedestrians is threatened if the foundation of the power transmission iron tower is seriously settled.
In the design and operation maintenance process of a conventional transmission line, under certain conditions, the condition that the foundation of a built tower is unevenly settled in the operation process may be caused due to various reasons, so that the tower is inclined, an insulator is obliquely damaged, if the foundation is not timely treated, great hidden dangers are caused to the safe operation of the transmission line, the common traditional scheme is to select a new site to build a tower position or reinforce the built foundation, the tower and the foundation which are in live operation do not have the condition of old demolition and new construction, or the construction cost of newly building or reinforcing the foundation is high, so that serious secondary waste is caused, and the conventional method has great difficulty in performing limiting correction on the tower under the specified constraint condition, so the requirement on an easily-implemented technical scheme capable of performing in-situ correction is very urgent for the building and operation and maintenance departments of the transmission line.
