Eachlength of pipe must be mechanically pushed "home" with a block and a push-bar against the sectionpreviously laid or pushed by means of block and push-bar and held in place until the trench and bedding are prepared for the next pipe section. Care must be taken in laying the pipe so as not to damage the bell end of the pipe. Mechanical means consisting of a cable placed inside the pipe with a winch, jock or come-along shall be considered to pull the pipe "home" where pushing the pipe will not result in a joint going "home" and staying in place. Use of hydraulic excavating equipment as the means of pushing ormoving the pipe to grade will not be permitted.
