Bends, tees and other PVC fittings shall be restrained with the use of thrust blocking or other restraint products as indicated in the construction documents. PVC gasketed, push-on fittings and mechanical restraints, if used, must be installed per the manufacturer’s guidelines. Connections for Gravity Sanitary Sewer and Non-Pressure Applications The connections are to be used in conjunction with tie-ins to other non-pressure, gravity sewer piping and/or structures, and shall be as indicated in the construction documents or approved by the Owner. 3.4 Grout Grout for use as a filler of the annular space between the liner pipe and the host pipe shall be a low-density, highly flowable mix. Grout shall meet the compressive strength requirements for the installation per the contract documents. Testing requirements shall be in accordance with the contract documents. Contractor may incorporate grout additives to improve its flow properties, provided that strength property requirements are met. 3.5 Pipe Pull Heads Pipe pull heads, if utilized, shall employ a positive through-bolt design assuring a smooth walled bolt against the pipe cross-section at all times. Pipe pull heads shall be specifically designed for use with fusible polyvinylchloride pipe, and shall be as recommended by the pipe supplier. 3.6 Pipe Rollers Pipe rollers, if required, shall be of sufficient size to fully support the weight of the pipe during handling and pullback operations. A sufficient quantity of rollers and spacing, per the pipe shall supplier’s guidelines be used to assure adequate support and resist excessive sagging of the product pipe.
