The utility model relates to the technical field of heat distribution pipelines, in particular to a large-diameter heat preservation pipe capable of evenly foaming, which comprises a working pipeline, a protective shell coaxially wrapping the working pipeline and a heat preservation layer filled between the working pipeline and the protective shell, and a supporting structure used for supporting the protective shell is further arranged between the working pipeline and the protective shell. The supporting structure comprises a plurality of supporting cushion blocks which are slidably connected between the working pipeline and the protective shell in the axis direction, the supporting cushion blocks are circumferentially arranged outside the working pipeline at equal intervals, and the working pipeline and the protective shell are each provided with a guide structure which is slidably connected with the supporting cushion blocks and used for limiting the sliding direction of the supporting cushion blocks.
