一、解决各种通风管道相碰及和谐的准则，通常为：小管让大管，有压让无压”冷、热水管与下水管相碰，则应改变冷、热水管道。

First, to solve various ventilation ducts collision and harmony criteria, usually: the tube let the large pipe, the pressure let no pressure "cold, hot water pipe and the lower pipe touch, then the cold and hot water pipes should be changed.

二、为了减少出资，节约空间，下降层高，有些敷设无斜度请求的通风管道，能够穿梁敷设。如果想要了解更多关于通风管道的留意事项，能够咨询咱们咱们会为你效劳的!

Two, in order to reduce investment, save space, reduce storeys, and lay some ventilation pipes without slope request, they can wear beams. If you want to know more about the ventilation pipe, you can consult us. We will do it for you.

三、关于相对杂乱的民用修建，通风管道在设计阶段，各工种(暖通、给水排水，供电照明与修建专业)首先应洽谈好空间分隔，定出每种管道的标高范围。通常情况下不得越出给自个规则的边境。遇有个别管段要越界时应与别的工程洽谈。

Three, on the relatively random civil construction, the ventilation pipe in the design stage, the various types of work (HVAC, water supply and drainage, power supply lighting and construction major) first should negotiate a good space separation, set up the range of each pipeline. Usually, it is not allowed to go beyond the borders of the rules. When there is a paragraph to cross the border, you should negotiate with other projects.

四、施工前应设备总管的工程师，将各工种的管线，单线画在一张平面图上。每种管道用一种彩色笔。各交点处归纳其标高，看是否有矛盾的地方，及时发现，将疑问解决在装置之前。

Four. Before the construction, the engineer of the equipment mains shall draw the pipeline and single line of each kind of work on a floor plan. Each type of pipe is used with a color pen. At each intersection, we should sum up its elevation to see if there is any contradiction, and find out in time that the problem will be solved before installation.
