5、提供的管材和管件符合国家现行的相关产品标准。实物与资料内容一致,且附有产品说明书和质量合格证;
5. The pipe materials and pipe fittings provided are in accordance with the relevant national product standards. The material object is consistent with the information, and the product specification and quality certificate are attached.

6、施工前应详细了解建筑物的结构情况,并根据设计图纸和施工方案制定与土建工程及其它相应工程的配合施工;
6. Understand the structure of the building in detail before construction, and work out the cooperation with civil engineering and other relevant projects according to the design drawings and construction plans;

7、施工人员经专业培训,熟悉W型柔性抗震接口铸铁排水管管道的结构、性能、装配技能,熟练掌握操作要点;
7. After professional training, the construction personnel are familiar with the structure, performance and assembly skills of w-type flexible anti-seismic interface cast iron drain pipe, and have a good command of operating points;

8、安装前,应对管材外观和管件接头进行认真检查,管材、管件上的污物和杂质应及时清除,对不符合质量要求的管材和管件及时通知供货商,不得使用。
8, before installation, carefully check should be made for pipe and pipe fitting joint appearance, the dirt and impurities on the pipes, pipe fittings shall be removed in a timely manner, does not meet the quality requirements of pipes and pipe fittings, promptly notify the supplier shall not be used.

二、W型柔性抗震接口铸铁排水管的操作要点之测量、放线
Measurement and wiring of w-type flexible anti-seismic interface cast iron drain pipe

1、按施工图测量、放线、定位,穿越楼板面和墙体的预埋的套管比所需管径大一号设置;
1. According to the construction drawings, the pre-embedded casing pipe across the floor and wall is one size larger than the required pipe diameter.

2、按施工图测量、放线,并根据其结果确定所需管材长度;
2. Measure and line according to the construction drawing, and determine the required pipe length according to the results;

3、按照所需管材长度确定支、吊架布置的位置.
3. Determine the position of supports and hangers according to the required pipe length.

三、W型柔性抗震接口铸铁排水管的操作要点之管道支、吊架安装
Iii. Installation of pipe support and hanger for w-type flexible anti-seismic interface cast iron drain pipes

1、排水立管采用支架固定在建筑物承重结构上,立管支架为每层设置,并应在直管段上部卡箍下方。支架间距不大于1.5m,但层高小于或等于3m时可只设一个立管支架。
1. The drainage riser is fixed in the building's load-bearing structure with a bracket. The riser bracket is set for each floor and should be below the upper clamping band of the straight pipe section. The bracket spacing should not be greater than 1.5m, but only one riser bracket can be set when the storey height is less than or equal to 3m.

2、排水横干管采用支架或吊架固定时,详见排水横管吊架示意图
2. When the drainage trunk pipe is fixed by bracket or hanger, please refer to the schematic diagram of the drainage trunk hanger

排水横管每3m设两个支(吊)架,支(吊)架应靠近接口部位设置(卡箍式接口不得将管卡套在卡箍上),与接口间的净距不大于30㎜。
Set two horizontal drainage pipe every 3 m (lift), a (lift) should be near the interface parts set (clamp-on interface pipe card must not be set on the clamp), and the interface between the clear distance not greater than 30 ㎜.

排水横管支(吊)架与接入或水平管中心线的距离为300~500㎜。排水横管在平面上转弯时,弯头处增设支(吊)架。排水横管起端和终端采用防晃支架或防晃吊架固定。当横干管长度较长时,为防止管道水平位移,横干管直线段防晃支架或防晃吊架的设置间距不大于12m。
Horizontal drainage pipe (lift) and the access or the distance of the center line of the horizontal tube is 300 ~ 500 ㎜. When the drain pipe turns on the plane, a branch (crane) is added at the elbow. The start and end of the drain cross pipe shall be fixed by anti-sway bracket or anti-sway hanger. When the length of the transverse trunk pipe is long, in order to prevent horizontal displacement of the pipeline, the spacing between anti-sway bracket or anti-sway hanger of the straight section of the transverse trunk pipe shall not be greater than 12m.

3、支、吊架螺丝孔径≤M12的,不得使用气焊开孔、切割、扩孔,应使用台钻进行开孔。螺丝孔径≥M12的,如用气焊开孔、切割时应对开孔或切割处进行处理。支、吊架孔眼及支架边缘应光滑平整,孔径不得超过穿孔螺丝直径5㎜。
3. If the screw hole diameter of the support frame and hanger is less than or equal to M12, it shall not use gas welding to open, cut or enlarge the hole, and shall use bench drill to open the hole. If the diameter of screw hole is greater than or equal to M12, for example, the hole opening or cutting place shall be handled when using gas welding. , hanger perforation and stent edge should be smooth level off, the aperture shall not exceed 5 ㎜ perforation diameter screw.

4、管道支、吊架、托架的安装须符合下列规定:位置正确,安装平整牢固、成条线;与管道接触紧密,固定牢固,管道的吊架、吊杆垂直;固定在建筑物结构上的管道支、吊架、托架,不得影响结构安全。
4. Installation of pipe support, hanger and bracket shall comply with the following provisions: correct position, smooth and firm installation, and forming a line; Close contact with the pipe, firmly fixed, the pipe hanger, hanger rod vertical; Pipe supports, cranes and brackets fixed to the structure of the building shall not affect the safety of the structure.
