一、W型柔性抗震接口铸铁排水管管材和管件在安装前的准备:
I. preparation of w-type flexible anti-seismic interface cast iron drain pipe materials and pipe fittings before installation:

W型柔性抗震接口铸铁排水管管材和管件在安装前应先清洗,管内不得有泥、砂、石及其它杂物。
Type W flexible aseismic interface cast iron drain pipe and pipe fittings should be cleaned before installation. Mud, sand, stone and other debris should not be found in the pipe.

W型柔性抗震接口铸铁排水在安装前管材的切割口应清除切口的毛刺,外圆略锉并倒角。
The w-type flexible aseismic joint cast iron shall remove the burr of the incision, file the outer circle slightly and chamfer the pipe before installation.

W型柔性抗震接口铸铁排水管管材的切割可使用常用的切割金属的机具,如砂轮机、锯等,切割口应无毛刺,外圆用砂轮机倒角。
W-type flexible anti-seismic interface cast iron drain pipe can be cut with common metal cutting tools, such as grinding machine, saw, etc.

二、W型柔性抗震接口铸铁排水管管材和管件的安装方法有哪些之卡箍接口的操作步骤
Ii. The installation method of w-type flexible aseismic joint cast iron drain pipe and pipe fittings, what are the operation steps of the clamp joint

1、接口处的管外壁表面擦干净;
1. Clean the outer wall surface of the pipe at the interface;

2、将不锈钢卡箍先套在接口一端的管身上;
2. Put the stainless steel hoop on the pipe at the end of the interface first;

3、将橡胶圈的一头套在一个接口管的管口上(一般是套在已固定好的管子或管件这一端),并应套入至规定深度;
3. Put one end of the rubber ring on the pipe mouth of an interface pipe (usually at the end of the fixed pipe or pipe fitting) and insert it into the specified depth;

4、将橡胶圈的另一头向外翻转;
4. Turn the other end of the rubber ring outward;

5、将要连接的管件或直管的管口放入翻转的橡胶圈口内,校准方位,把翻转的橡胶圈口翻回正常状态;
5. The pipe fitting or pipe opening to be connected shall be put into the inverted rubber ring mouth, the orientation shall be calibrated, and the inverted rubber ring mouth shall be turned back to normal state;

6、再次校准管道的坡度或垂度或方位,初步用支吊架固定管道,移动不锈钢卡箍套在橡胶圈外,用专用套筒拧紧卡箍上的固紧螺栓,接口就完成。但应随即将支吊架上的螺栓拧紧,使管道可靠固定。
6, once again that the slope of the calibration pipe or sag or bearing, preliminary with steam-water pipes, mobile stainless steel clamp set outside the rubber ring, with a special tightening bolts on the sleeve tighten the clamp, the interface is complete. However, the bolts on the hanger should be tightened immediately so that the pipe can be fixed reliably.

、W型柔性抗震接口铸铁排水管管材和管件的安装方法有哪些之水平管道安装
Iii. What are the horizontal pipe installation methods of w-type flexible aseismic interface cast iron drain pipe materials and pipe fittings

1、支架安装:确定好管道安装的顺序和部位,依施工图管道标高确定管架规格、型号,并按此制作,涂刷油漆,按施工顺序编号。由于排水管安装有坡度,管架长短有区别,不可安错顺序。按管道安装原则,逆排水坡度方向固定支(吊)架。
1. Bracket installation: determine the sequence and location of pipeline installation, determine the specification and model of pipe rack according to the pipeline elevation of construction drawing, and make it according to this, paint it, and number it according to the construction sequence. Because of the slope of the drain pipe installation, the length of the pipe rack is different, not wrong order. According to the installation principle of pipeline, the support (crane) is fixed in the direction of reverse drainage slope.

2、管道安装:按柔性卡箍式离心排水铸铁管安装的一般要求,应逆水流方向安装。在安装管道之前,管支架必须先装好,当一个接口连接完成后,把连接好的管段牢牢地固定在支架上,防止发生位移造成安装偏差。由于管连接属于柔性接口,而且伸缩系数很小,不需设置伸缩补偿装置。必要时,每个连接口允许有少量偏转,但偏转角度最大不得大于3°。
2. Pipeline installation: according to the general requirements of flexible hoop type centrifugal drain cast iron pipe installation, it shall be installed in the direction of reverse water flow. Before installing the pipe, the pipe bracket must be installed. When an interface connection is completed, the connected pipe segment shall be firmly fixed to the bracket to prevent installation deviation caused by displacement. Since the pipe connection is a flexible interface and the expansion coefficient is small, there is no need to set up the expansion compensation device. When necessary, each connection mouth allowing a small amount of deflection, but maximum shall not be greater than 3 ° deflection Angle.

四、W型柔性抗震接口铸铁排水管管材和管件的安装方法有哪些之垂直管道安装
Iv. What are the vertical pipe installation methods of w-type flexible aseismic interface cast iron drain pipe materials and pipe fittings

1、当立管穿越楼层安装时,立管穿楼板应采用刚性套管,屋面为刚性防水套管,用膨胀水泥砂浆填筑楼板孔洞。
1. When the vertical pipe is installed across the floor, rigid casing should be adopted for the vertical pipe through the floor. The roof is a rigid waterproof casing.

2、立管底部应用支墩或用加强型支(吊)架。由于卡箍只能承受一部分的轴向拉力和垂直方向的剪切力。依安装实际情况,若立管底部转弯处着地可采用90°的鸭脚弯头,则配件固定于地板上。
2. The bottom of the riser shall be supported by a pier or reinforced support (lifting) frame. Because the hoop can only bear part of the axial tension and vertical shear force. In accordance with the actual situation, if the bottom of the riser of can use 90 ° corner hit the duck feet bend, fittings fixed on the floor.

3、立管转弯处悬空转到水平位置,应在弯头底部设加强型固定支架。
3. When the vertical pipe turns to a horizontal position, a strengthened fixed bracket shall be installed at the bottom of the elbow.

排水支管起始端直接与洁具、地漏、雨水斗相连,直接承受水流的冲击扰动,所以支管固定问题更应重视。分以下三种情况分别固定:
The initial end of the drain branch pipe is directly connected to the sanitary ware, floor drain and rainwater hopper and directly suffers the impact disturbance of water flow. Therefore, the fixation of the branch pipe should be paid more attention to. Fixed in the following three cases:

(1)单个配件与管相连,在弯头底部加固定支架即可。
 (1) a single part is connected to the pipe and a fixed bracket is added at the bottom of the elbow.

(2)多个配件与管相连,每个配件处加固定支架和吊架并相互间隔。
 (2) multiple fittings are connected to the pipe, and fixed bracket and hanger are added at each part and separated from each other.

(3)在管配件比较密齐,几乎是管件相互连接时,应在管件下设置槽形管托,支(吊)架与管托相连接,固定支架和吊架相互间隔,每3米一个。
 (3) in the pipe fittings is more close together, is almost pipe connection, each other should be set up under the pipe trough pipe bracket, bronchitis (hanging) frame connected to pipe bracket, the spacing between fixed support and hanger, every 3 meters.
