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

　　①輸送易燃、可燃?xì)怏w的管道不得和其他管道同溝敷設(shè)。

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

　　②冷、熱水管道，蒸汽管道必須進(jìn)行保溫。

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

　　③管道外壁(或保溫層的外表面)距墻面或溝壁的距離不應(yīng)小于0.15m，距柱、梁之間的距離可為0.05m，各種管道外壁(或保溫層外表面)之間的距離為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風(fēng)道的外壁距墻之間的距離宜為0.2~0.3m。斷面小的用小距離，斷面大的用大距離。

　　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管道同溝或共架敷設(shè)時(shí)，冷，熱鬧水管應(yīng)在上面給排水管應(yīng)在下邊，且給水管應(yīng)在下邊，且給水管應(yīng)在排水管上邊。

　　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風(fēng)管、水管穿樓板，穿墻時(shí)，留孔尺寸的大小如下：不保溫風(fēng)管的洞為風(fēng)管尺寸加100mm，保溫風(fēng)管為風(fēng)管尺寸加150mm;不保溫水管的洞一般比管徑大兩號(hào)，而保溫水管的留洞尺寸為管徑加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.
