FIELD: structure of stand pipes (storey stand pipes) of sewer system, cold and hot water supply systems, complete with piping lay out presenting a shaft package of storey stand pipes of full factory readiness. SUBSTANCE: shaft package presents carrying base in which stand pipes of cold and hot water are fastened by means of clamps, sewer stand pipe formed from sections of sewer pipe from polymer material, one of which has appliance for revision, and, at least, two other sections are made in form of cross piece. Pipe section is made with funnel on its one end which is made with circular beads on outer surface and circular widening on side of end face for location of gasket. Funnel in place of gasket location is made from outer side with cone-shaped side surface. Hollow of its circular widening is open from end and limited by removable cover with central hole with circular surface corresponding to indicated taper of funnel limited on smaller diameter by circular surface whose inner diameter is not smaller than pipe diameter out of funnel, and on larger diameter, by internal circular projection of segment-shaped cross-section. Section of cone- shaped side surface of funnel exceeds depth of location of gasket in its circular widening and forms recess between base of conical part and nearest to it circular bead of pipe for location of circular projection of removable cover.
