Well chamber wall heat supply pipeline supporting waterproof device

The invention belongs to the technical field of centralized heating waterproofing, and particularly relates to a well chamber wall heat supply pipeline supporting waterproof device which comprises an outer pipe sleeve, an elastic supporting piece, a sealing piece and a limiting ring plate, the elastic supporting piece comprises a plurality of W-shaped elastic pieces arranged in a straight line, and every two adjacent W-shaped elastic pieces are integrally connected through a transverse plate; the sealing piece comprises an annular sealing ring body, arc protruding parts are arranged on the outer surface of the annular sealing ring body at equal intervals, and Y-shaped protruding parts are arranged on the inner surface of the annular sealing ring body. The sealing structure applied to the heat distribution pipeline is formed by combining the elastic supporting pieces and the sealing pieces, when the pipeline deforms, the W-shaped elastic pieces are compressed by the deformation parts, and the sealing pieces at
