球墨铸铁管施工经验技巧

1、为了安装方便,可先用水浸湿橡胶圈。
1. For the convenience of installation, wet the rubber ring with water first.

2、炎热的夏季,润滑油宜用植物油;寒冷的冬季,橡胶圈可用热水预热,以减少硬度,迅速安装。
2. Vegetable oil is suitable for lubricating oil in hot summer; In cold winter, the rubber ring can be preheated by hot water to reduce hardness and install quickly.

3、球墨铸铁管安装中若需借转,在用管子的自身借转角无法满足的情况下,可根据需借转的角度,经计算后将球墨铸铁管管子的插口切割后斜口,这样既可增大借转角度,又能保证安全使用。
3.If the ductile iron pipe needs to be rotated during the installation, it can be cut into the ductile iron pipe after calculation according to the Angle of rotation required when the pipe's own rotation Angle cannot be satisfied, which can not only increase the Angle of rotation but also ensure safe use.

4、球墨铸铁管若无条件用水试压时,也可考虑用空气试压。
4.  If the ductile iron pipe is tested with water unconditionally, air test may also be considered.

5、管沟回填应分层夯实,若管道穿越道路时,为避免压坏管身,可回填粗砂至管顶。
5. The backfill of the pipe trench shall be laminated and compacted. If the pipe crosses the road, coarse sand can be backfilled to the top of the pipe to avoid damaging the pipe body.

6、在施工中有时会发生接口滴漏。为避免此现象,在安装时需严格按规范进行施工,需保证给每根管子都安装到位,对于大口径的管道需检查每个接口胶圈的情况。
6. Interface leakage will sometimes occur during construction. In order to avoid this phenomenon, construction should be carried out in strict accordance with the specifications during installation, and every pipe should be installed in place. For large-caliber pipe, every interface rubber ring should be checked.

7、夏季施工过程中,可在接口部位适当覆土。
7. During the summer construction, the soil may be covered at the interface properly.

8、三通、弯头必须做混凝土支墩。
8. Concrete piers must be made at tee and elbow.
