标准范围

ISO 11295:2017定义并描述了通过使用塑料管（包括在管道、配件和辅助组件中原位形成的塑料复合材料）对非压力和压力管道进行翻新和非开挖更换（在现有管道线上或线下）的技术系列。它不包括作为网络扩展提供的新建筑。对于每个技术系列，它确定了应用领域，包括但不限于地下排水和下水道，以及地下水和天然气供应网络。ISO 11295:2017提供了用于现有管道翻新或非开挖更换的塑料管道系统的设计原则，但未提供详细方法，包括:-现有管道和现场条件；-新管道的功能；-结构性能；-水力性能；-安装方面和现场影响；-影响翻修或非开挖置换技术选择的其他因素。在翻新和/或非开挖更换之前，对现有管道进行必要的工作不在ISO 11295:2017的范围内。ISO 11295:2017提供了确定可行方案和确定与给定康复目标相关的最佳技术所需的信息。注:设计师有责任选择和设计翻修或非开挖更换系统。它没有规定计算方法，以确定每种可行技术所需的衬里或更换管道材料的数量，以确保修复后管道的预期性能。

ISO 11295:2017 defines and describes families of techniques for the renovation and trenchless replacement (on or off the line of an existing pipeline) of non-pressure and pressure pipelines through the use of plastics pipes, including plastics composites formed in situ into pipes, fittings and ancillary components. It does not include new construction provided as network extension. For each technique family, it identifies areas of application including, but not limited to, underground drainage and sewerage, and underground water and gas supply networks.ISO 11295:2017 provides information on the principles of, but not the detailed methodologies for, the design of plastics piping systems used for renovation or trenchless replacement of existing pipelines, covering:- existing pipeline and site conditions;- functions of the new pipeline;- structural performance;- hydraulic performance;- installation aspects and site impact;- other factors affecting renovation or trenchless replacement technique selection.Necessary work on the existing pipeline prior to renovation and/or trenchless replacement is outside the scope of ISO 11295:2017.ISO 11295:2017 provides information needed to determine viable options and for identification of the optimal technique with regard to a given set of rehabilitation objectives.NOTE It is the responsibility of the designer to choose and design the renovation or trenchless replacement system.It does not specify the calculation methods to determine, for each viable technique, the required amount of lining or replacement pipe material needed to secure the desired performance of the rehabilitated pipeline.
