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）對于比較復雜的民用建筑，在設計階段，各工種（暖通、給水排水，供電照明與建筑）首先應協商好空間分隔，定出每種管道的標高范圍。一般情況下不得越出給自己規定的界限，遇有個別管段要越界時應與其他工程協商。

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）解決各種通風管道相碰及協調的原則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風管相撞，則應當自來水管拐彎。冷、熱水管與下水管相碰，則應改變冷、熱水管道。

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）施工前應設備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種通風管道用一種彩色筆，在各交點處綜合其標高，看是否有矛盾之處，及時發現，將問題解決在安裝之前。

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）為了減少投資，節省空間，降低層高，有些敷設無坡度要求的通風管道，可以穿梁敷設（如自來水管道，消防噴灑干管等）。

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.).
