Rectification foundation for high-voltage power transmission tower on goaf site and rectification method of rectification foundation

Abstract

The invention discloses a rectification foundation for a high-voltage power transmission tower on a goaf site and a rectification method of the rectification foundation. The rectification foundation comprises a foundation body, wherein a spherical rotary joint is preburied in the top of the foundation body and is fixed to telescopic supporting legs through a connecting base. According to the rectification foundation, the tower is rectified without damaging the foundation body, so that the shortcoming that the foundation has to be replaced in a traditional method is avoided, the cost is lowered. The number of the telescopic supporting legs which need to be adjusted and the adjusting scale value of a telescopic rod of each telescopic supporting leg are determined through calculation, so thatthe adjustment is more accurate. When the transmission tower and the telescopic supporting legs are dislocated, the spherical rotary joint can be rotated and adjusted to enable the bottom connectingpart of the transmission tower to be re-matched with bolted holes in the upper parts of the telescopic rods. The adjustment process is simple and efficient. A very high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of deflection correction for high-voltage transmission towers, in particular to a deflection-correctable foundation and a deflection-correction method for a high-voltage transmission tower in a goaf site. Background technique [0002] my country is rich in coal resources. In the past few decades, the huge annual coal output during the development of old energy sources has also made the area of ​​ground subsidence caused by coal mining continue to expand. In recent years, with the process of global economic integration, human beings' demand for energy has become more urgent than in the past. The sharp increase in electricity consumption has led to a steady increase in the number of transmission towers. With the increase in the number of large transmission towers, some areas The pylons that are available have to pass through the gob site in the field environment. Due to the non-directional nature of the wind,...

Problems solved by technology

[0003] At present, when the high-voltage transmission tower in the goaf site settles, the foundation is generally reconstructed in the form of destroying the foundation. The whole process is time-consuming and laborious, and a certain cost is incurred; Although the inclination adjustment device of the transmission tower in the district can play a certain role in correcting the deviation when the transmission tower is tilted, its foundation only lifts the base through the jack, and can only correct part of the settlement in the vertical direction, and the length of the loosened anchor bolts tops The lift is limited, and when the foundation is dislocated in the horizontal direction, the anchor bolt holes have deviated from the vertical direction, and the position where the main material legs of the iron tower connect to the main tower is also dislocated, but this technical solution cannot freely adjust the connection length with the tower and angle, it has great limitations when rectifying the high-voltage transmission tower in the gob site
