Chemical heat production maintenance device for power transmission line pile construction and maintenance method thereof

The invention relates to a chemical heat production maintenance device for power transmission line pile construction and a maintenance method thereof. A colored steel sheet is utilized to enclose a barrel-shaped space to surround an exposed part of a power transmission line pile, an upper part of the barrel-shaped space is covered by a quilt, a tripod is utilized to support a reaction liquid barrel in the barrel-shaped space, the reaction liquid barrel is used for accommodating a methanol solution with the volume concentration as 20%, the methanol solution drops out through a dropping device to generate combination reaction with quick lime in a quick lime box to release heat to maintain power transmission line piles, and the flow of the reaction liquid can be adjusted by an adjusting device. The chemical heat production maintenance device disclosed by the invention has the beneficial effects: the 20% methanol solution is utilized to replace water to react with the quick lime to releaseheat, a solidifying poin
