What are the basic methods for pipe laying? The following are introduced by the professional personnel of ventilation pipe:

　　①输送易燃、可燃气体的管道不得和其他管道同沟敷设。

　　① Pipelines conveying inflammable and combustible gases shall not be laid in the same trench as other pipelines.

　　②冷、热水管道，蒸汽管道必须进行保温。

　　② Cold and hot water pipes and steam pipes must be insulated.

　　③管道外壁(或保温层的外表面)距墙面或沟壁的距离不应小于0.15m，距柱、梁之间的距离可为0.05m，各种管道外壁(或保温层外表面)之间的距离为0.1~0.15m。

　　③ The distance between the outer wall of the pipeline (or the outer surface of the insulation layer) and the wall or trench wall shall not be less than 0.15m, the distance between the outer wall of the pipeline (or the outer surface of the insulation layer) and the column and beam shall be 0.05m, and the distance between the outer walls of various pipelines (or the outer surface of the insulation layer) shall be 0.1 ~ 0.15m.

　　④风道的外壁距墙之间的距离宜为0.2~0.3m。断面小的用小距离，断面大的用大距离。

　　④ The distance between the outer wall of the air duct and the wall should be 0.2-0.3m. If the section is small, use small distance; if the section is large, use large distance.

　　⑤管道同沟或共架敷设时，冷，热闹水管应在上面给排水管应在下边，且给水管应在下边，且给水管应在排水管上边。

　　⑤ When the pipes are laid in the same trench or on the same frame, the water supply and drainage pipes shall be on the top of the cold and busy pipes, and the water supply pipes shall be on the bottom, and the water supply pipes shall be on the top of the drainage pipes.

　　⑥风管、水管穿楼板，穿墙时，留孔尺寸的大小如下：不保温风管的洞为风管尺寸加100mm，保温风管为风管尺寸加150mm;不保温水管的洞一般比管径大两号，而保温水管的留洞尺寸为管径加150mm。

　　⑥ When the air pipe and water pipe pass through the floor and the wall, the size of the reserved hole is as follows: the hole of the uninsulated air pipe is the air pipe size plus 100 mm, and the insulated air pipe is the air pipe size plus 150 mm; the hole of the uninsulated water pipe is generally two sizes larger than the pipe diameter, and the reserved hole size of the insulated water pipe is the pipe diameter plus 150 mm.
