PPR管施工方案
PPR管道施工工艺 PPR pipe installation method
编制依据Basis of drawing up
《给水排水管道工程施工及验收规范》GB50268-97。
《Construction and acceptance norm of Water supply and drains piping engineering》。
《室内管道支架及吊架》03S402《Piping support indoor》。
施工工艺:Construction technique:
根据现场各种管线布置情况和流程顺序确定工艺流程,本工程采用如下工艺流程:施工准备→材料进货检验→PPR管预制加工→支吊架制作安装→PPR管安装→PPR管试验
According to the arrangement and flow order of field all kinds of pipelines, confirm the process flow. This engineering adopts the following process flow: construction preparation→material stocking test→PPR pipe pre-processing→manufacture and installation of support and hanger→installation of PPR pipe→PPR pipe test
施工准备:Construction preparation
施工工作及技术人员认真熟悉原图纸,领会设计意图,对图纸中和实际管道布置清楚后,才能施工。
Construction work and technicians are strictly familiar with the original drawing, comprehend design purpose, and carry out the construction after the clarity to drawing and actual pipeline arrangement.
施工人员须熟悉PPR管的一般性能,掌握必须的操作要点。在各项预制加工项目开始前,根据实际编制材料计划,将需要的材料、设备等按规格、型号准备好,运至现场。
Constructer must know well the general performance of PPR, master necessary operation points,Before each precast processing project, according to the plan of practical scheduling material, well prepare the needed material and equipment according to specification and model and transport to the field.
材料设备要求:到现场的管材、管件等提供的管材和管件应符合设计规定,并附有产品说明书和质量合格证书,须认真检查并经业主验明材质,核对质保书,规格、型号等,合格后方能入库,并分别作好标识。
Material equipment requirements: The offered field pipe and pipe fittings should accord with design prescription, adding with product stipulation and quality certification. Strictly examine and identify material by owner, check quality guarantee, specification and models etc, warehouse after qualification, and mark separately.
管材和管件的内外壁应光滑平整,无气泡、裂纹、脱皮和明显的痕纹、凹陷,色泽应基本一致。不得使用有损坏迹象的材料。如发现管道质量有异常,应在使用前进行复检。
The internal and external surface of pipe and pipe fittings should be smooth and flat, without air bla
