PART 3 EXECUTION <br /> 3.1 GENERAL <br /> A. All polyethylene pipe shall be cut, fabricated, and installed in strict conformance <br /> with pipe manufacturer's recommendations. Joining, laying, and pulling of <br /> polyethylene pipe shall be accomplished by personnel experienced in working <br /> with polyethylene pipe. <br /> B. Pipe shall be joined and placed in such a manner as to prevent damage to the <br /> HDPE Geomembrane Lining and other underlying geosynthetics. <br /> 3.2 TRANSPORTATION <br /> A. Care shall be taken during transportation of the pipe such that it is not cut, kinked, <br /> or otherwise damaged. <br /> 3.3 STORAGE <br /> A. Pipes shall be stored on level ground, preferably turf or sand, free of sharp objects <br /> that could damage the pipe. Stacking of the polyethylene pipe shall be limited to a <br /> height that will not cause excessive deformation of the bottom layers of pipes <br /> under anticipated temperature conditions. Where necessary due to ground <br /> conditions, the pipe shall be stored on wooden sleepers, spaced suitably and of <br /> such widths as not to allow deformation of the pipe at the point of contact with the <br /> sleeper or between supports. <br /> 3.4 HANDLING PIPE <br /> A. The handling of the joined pipeline shall be in such a manner that the pipe is not <br /> damaged by dragging it over sharp and cutting objects. Ropes, fabric, or <br /> rubber-protected slings and straps shall be used when handling pipes. Chains, <br /> cables, or hooks inserted into the pipe ends shall not be used. Two slings spread <br /> apart shall be used for lifting each length of pipe. Pipe or fittings shall not be <br /> dropped onto rocky or unprepared ground. Slings for handling the pipeline shall <br /> not be positioned at butt-fused joints. Sections of the pipes with cuts and gouges <br /> exceeding 10 percent of the pipe wall thickness or kinked sections shall be <br /> removed and the ends of the pipeline rejoined. <br /> 3.5 JOINING PIPE SECTIONS <br /> A. Pipes shall be joined to one another, to the polyethylene fittings, and to the flange <br /> connections by means of thermal butt-fusion. Polyethylene pipe lengths, fittings, <br /> and flanged connections to be joined by thermal butt-fusion shall be of the same <br /> type, grade, and class of polyethylene compound and supplied from the same raw <br /> material supplier. <br /> Forward Landfill WMU FU-04 <br /> 02535 3 LEACHATE PIPES <br />
