The present invention discloses an insulation structure for a through-wall pipe of waste heat boilers of combustion engine electricity plants, comprising inner heat pipes for conveying hot water, inner deformation rings provided on the outer wall of the inner heat pipe, the outer side wall of the insulation ring is provided with sensing members for changes in the shape variable of the inner heat pipe, the sensing member is connected to the rubber gas tube by gas transfer members. The invention conveys hot water through the inner heat pipe, and the inner deformation ring set on the inner heat pipe assumes the shape variable of the inner heat pipe when it is heated, when the inner heat pipe is deformed, the outer pipe inside the inner deformation ring will deform in time and create space for translation, which will not affect the release of pressure from the inner heat pipe.
