A pipe construction kit for a sewer pipeline comprises several pipes made of plastic, which exhibit a circular cross-section. Between in each case two pipes there is to be arranged a shaft base body made of plastic, exhibiting a central connection section. The connection section exhibits a foot having a supporting surface and, diametrically thereto, a connection element for a shaft. On both sides of the connection section there are formed pipe sections for connection with the pipes. The diameter d of the shaft is significantly smaller than the diameter D of the shaft base body.
