(a) Each pipe shall be laid on an even, firm bed so that no uneven strain will come to any part of the pipe. Particular care shall be exercised to prevent the pipes bearing on the sockets. Bell holes for bell and spigot pipe shall be dug at each point as hereinbefore specified. Each pipe shall be laid in conformity with the line and grade stakes and in the presence of the Inspector. The bell-end of the pipe shall be laid upgrade.
(b) The interior of the sewer shall, as the work progresses, be cleaned of all dirt, jointing material and superfluous materials of every description. On small pipe sewers where cleaning after layout may be difficult, a swab or drag shall be kept inside the pipe line and pulled forward past each joint immediately after its completion.
(c) All pipe shall be completely shoved home. On pipe of the tongue and groove type, thirty inches in diameter and larger, pressure must be applied to the center of each pipe as it is laid by a winch and cable or other mechanical means properly set and operated to insure that the tongue is all the way home in the socket and that the sewer joint is of uniform size throughout the circumference of the pipe.
