The heat insulation layer structure comprises a first heat insulation layer and a second heat insulation layer which are connected in a lap joint mode, and the heat insulation plate is arranged at the lap joint position of the two heat insulation layers. And the heat-resistant plate is welded on the inner metal skin to prevent high-temperature air from leaking. The mounting method comprises the following steps: step 1, placing: placing the heat-resisting plate at the lap joint of the first heat-insulating layer and the second heat-insulating layer, and lapping the heat-resisting plate on the inner metal skins of the first heat-insulating layer and the second heat-insulating layer; 2, welding is conducted, specifically, a pre-welding position is marked before welding, a welding area is determined, then the two ends of the heat resisting plate are aligned and pressed with the inner metal skins of the two heat insulating layers correspondingly, and the contact positions of the heat insulating plate and the two i
