通风管道的安装施工是非常重要的工作，不仅要配合工程中的其他工种，自身的布局设计还很有难度的。那么，通风管道是如何施工的呢？
The installation and construction of ventilation pipes is a very important work. It is not only necessary to cooperate with other types of work in the project, but also difficult to design its own layout. Then, how is the ventilation duct constructed?
1）对于比较复杂的民用建筑，在设计阶段，各工种（暖通、给水排水，供电照明与建筑）应协商好空间分隔，定出每种管道的标高范围。一般情况下不得越出给自己规定的界限，遇有个别管段要越界时应与其他工程协商。
1) For complex civil buildings, in the design stage, all types of work (HVAC, water supply and drainage, power supply and lighting and building disciplines) shall first negotiate the space separation and determine the elevation range of each pipe. In general, it is not allowed to exceed the limits specified for itself. In case of crossing of individual pipe sections, it is necessary to negotiate with other projects.
2）各种通风管道相碰及协调的原则，一般为：“小管让大管，有压让无压”。例如，自来水管与风管相撞，则应当自来水管拐弯。冷、热水管与下水管相碰，则应改变冷、热水管道。
2) The principle to solve the collision and coordination of various ventilation pipes is generally: "small pipe gives way to large pipe, pressure gives way to no pressure". For example, if the water pipe collides with the air pipe, the water pipe should be turned. If the cold and hot water pipes collide with the downcomer, the cold and hot water pipes shall be changed.
3）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。每种通风管道用一种彩色笔，在各交点处综合其标高，看是否有矛盾之处，及时发现，将问题在安装之前。
3) Before construction, the engineer of the equipment manager shall draw the pipelines and single lines of each type of work on a plan. Use a color pen for each type of ventilation pipe, synthesize its elevation at each intersection, see if there is any contradiction, find it in time, and solve the problem before installation.
4）为了减少投资，节省空间，降低层高，有些敷设无坡度要求的通风管道，可以穿梁敷设（如自来水管道，消防喷洒干管等）。
4) In order to reduce investment, save space and reduce floor height, some ventilation pipes without slope requirements can be laid through beams (such as water pipes, fire sprinkler main pipes, etc.).
