【国外标准】 Standard Guide for Insertion of Flexible Polyethylene Pipe Into Existing Sewers

4.1 The procedures described in this guide are intended as a design and review aid for use by the design engineer in conjunction with manufacturer's recommendations for installing a polyethylene pipe using the insertion method.1.1 This guide describes design and selection considerations and installation procedures for the rehabilitation of sanitary and storm sewers by the insertion of solid wall or profile wall or corrugated polyethylene pipe into an existing pipe and along its existing line and grade. The procedures in this guide are intended to minimize traffic disruption, surface damage, surface restoration and interruption of service.1.2 The polyethylene piping product manufacturer should be consulted to determine the polyethylene piping product’s suitability for insertion renewal as described in this guide.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See 6.1, 7.1, and 8.1 for additional safety precautions.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
