A foundation reinforcement and overall rectification and translation method for high-voltage transmission towers in subsidence areas

Abstract

The invention discloses a foundation reinforcing and integral inclination rectifying and shifting method for a high-voltage transmission tower in a subsidence area; the method comprises: adding a concrete structure or a steel-structure reinforcing beam between any two adjacent independent foundations of a tower so that the four independent foundations of the tower are reinforced into an integral conjoined foundation, wherein each reinforcing beam is provided with extension stems extending from two ends to the outside by preset length; using a jacking mechanism to raise the conjoined foundation from beneath the extension stems, adjusting top elevation of the conjoined foundation to the same horizon; setting up stays around the tower to prevent falling; using the jacking mechanism to raise the tower, and arranging travelling devices for shifting the tower at the lower portion of the conjoined foundation; using the travelling devices to shift the tower; after the tower is shifted to a predetermined position, removing the travelling devices, backfilling the conjoined foundation, and removing the stays. The method has the advantages that construction operations are simple, the foundation is effectively reinforced, rectified and shifted, the method is good in safety and reliability and highly adaptable, power interruption for operation is not required, and underground normal production is unaffected.

Description

Technical field [0001] The invention relates to the technical field of protection of high-voltage power transmission towers in subsidence areas, in particular to a method for strengthening the foundation of high-voltage transmission towers in subsidence areas and overall tilt correction and translation. Background technique [0002] At present, when the high-voltage transmission line is overwhelmed by underground resources, it will encounter the problem of the movement and deformation of the subsidence area that affects the safety of the high-voltage transmission line. The general method is to reroute and rebuild the high-voltage transmission line or to leave a protective pillar underground. However, it takes a lot of money and time to rebuild and rebuild transmission lines. During this period, power outages are required, which affects normal production and living power; leaving a protected mine pillar causes a huge waste of underground resources, affects the normal production ord...
