4) Sealing the joint of the plugging plate and the roof tile at the edge of the pitched roof;
5) Pouring foaming cement heat-insulating slurry at a pouring opening of a cast-in-situ heat-insulating layer formed at the upper part of a pitched roof; gradually pouring along the transverse direction of the pitched roof during pouring; in the pouring process, layered pouring is adopted along the gradient direction of a pitched roof until the position, which is 10-30 cm away from the pouring opening of the cast-in-place heat-insulating layer, in the heat-insulating layer accommodating cavity is stopped from pouring, after initial setting, foaming cement heat-insulating slurry is secondarily supplied to the pouring opening of the cast-in-place heat-insulating layer, and the whole pouring opening of the cast-in-place heat-insulating layer is ensured to be filled after foaming;
6) After the foaming cement thermal insulation slurry of the pouring opening of the cast-in-situ thermal insulation layer is initially set, a ridge cover plate is installed;
7) Self-curing: the self-curing period is not less than 7 days.
