UNDERGROUND PIPING INSTALLATION 地下管道的安装 SCOPE 范围 This Specification, accompanied by other applicable specifications, drawings and details, covers the requirements for field handling, storage, fabrication and installation of ferrous metallic and non-metallic underground piping systems. Wherever a difference exists between this specification and the drawings, the drawing shall govern. No deviation shall be made from this specification without written approval from ***l. In principle handling, storing and installations shall be in accordance with manufacturers instructions. This specification shall be used in conjunction with the Combined Underground and Paving Plan, herein after called CUPP, and a package, containing standardized details, General Notes and References. 本规范，及其他适用的规范、图纸和详细资料，涵盖了铁质金属和非金属地下管道的现场搬移、储存、预制和安装的要求。如果本规范和图纸之间出现差异，应以图纸为准。没有***的书面许可，不得对本规范进行变更。 原则上，管道的搬移、储存和安装应按照生产商的要求进行。本规范应结合“合并地下工程和铺路方案”（下称CUPP）和包含标准化详细规定、总体说明和参考文件的文件包使用。 DEFINITIONS 定义 Underground Piping is understood to be assemblies of pipe, flanges, gaskets, fittings, valves and other piping components. 地下管系理解为管道、法兰、垫圈、配件、阀门和其他管道配件的组合。 All dimensions are in millimeters. Elevations are given in meters relative to the local measurement system or referring to a local set point having an elevation of 100.000 which equals 10.50 in the local system. 所有的尺寸均为毫米。标高以米为单位，为与本地测量系统的相对值或者与本地控制点的对比值，控制点的标高为100.000(等同于本地系统中的10.50)。 Pipe joints are in principle not shown on the drawings and shall be in accordance with the applicable piping material specification 管道接头原则上没有在图纸上标出，应依据适用的管道材料规范。 Safe location: an open end of vent or relief piping is located in such a manner that maintenance and/or operating personnel are protected from gas and/or vapor sprays. 安全地点：端部没有封口的风管或者卸压管道，它能保护保养和/或操作人员不受气体和/或蒸汽喷射的伤害。 Branch line: A secondary sewer line used to direct sewer liquids from hubs, dry boxes or catch basis to sewer header lines 支管：二级污水管，用来将集水池、干箱或者窨井处的污水引流到污水总管处。 Catch basin: An open or grating covered concr
