Construction process of insulation board hole penetration and broken bridge insulation system of indoor skiing site

The invention discloses a construction process of an insulation board hole penetration and broken bridge insulation system of an indoor skiing site. The construction process comprises the following steps of top plate hole forming and positioning, sample top-plate-penetrating hole construction, airtight treatment and plugging treatment. For a pipeline or a suspender, firstly, hole positioning is conducted on the upper portion of a top plate, steel plates of a surface layer and a back layer are cut off through a high-altitude vehicle according to the size of a hole, a PIR core material in the top plate is removed, a sample is placed into the cut hole, foaming heat insulation treatment is conducted at the upper end of the hole of the top plate through a foaming agent, a color steel sleeve isarranged outside a foaming layer, then the color steel sleeve and the upper surface of the top plate are covered with an air separation layer, and the lower end of the top plate hole and the top of the foaming layer are seale
