工廠、寫字樓、酒店都會安裝通風管道，但是后期安裝多少肯定和之前的建筑的管線等有不可避免的接觸，那么通風管道安裝應該注意些什么呢？
The factory, the office building, the hotel will install the ventilation pipe, but the later installation is sure to have the inevitable contact with the pipeline of the building before, so what should the installation of the ventilation pipe be noticed?
1.施工前設備總管工程師應將各工種的管線、單線畫在一張平面圖上。每種管道用一種彩色筆。在各交點處綜合其標高，看是否有矛盾之處，及時發(fā)現(xiàn)問題，將問題解決在安裝之前，以免影響后期工程進程。
Before construction, the chief engineer of the equipment shall draw the pipeline and single line of each type of work on a plan. Each type of pipe is used with a color pen. At all points of intersection, it should synthesize its elevation to see if there is any contradiction, find problems in time, and solve the problems before installation, so as not to affect the later engineering process.
2.解決各種通風管道相碰及協(xié)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、熱水的管道。
The principles to solve the collision and coordination of various ventilation ducts are generally: "small pipes allow large pipes to be pressurized without pressure". For example, if the water pipe collides with the wind pipe, it should turn the water pipe. When cold and hot water pipes collide with the water pipes, the cold and hot water pipes should be changed.
3.為減少投資，節(jié)省空間，降低層高，有些敷設無坡度要求的管道，可以穿梁敷設，比如自來水管道，消防噴灑干管等，一切均合理規(guī)劃。
In order to reduce investment, save space and reduce the height of layers, some pipes with no slope requirements can be laid with beams, such as water pipe, fire sprinkler, and so on. All of them are reasonably planned.
4.對于比較復雜的民用建筑，在設計階段，暖通、水電、建筑等工種應協(xié)商好空間分隔，定出每種管道的標高和可施工范圍。一般情況下不得越出給自己規(guī)定的界限，遇有個別管段要越界時應與其他工程協(xié)商決定，以免出現(xiàn)不可預估的損失。
For more complex civil buildings, in the design stage, the HVAC, hydroelectric, building and other types of work should first negotiate a good space separation, set up the elevation and the scope of the construction of each kind of pipe. In general, we should not exceed the prescribed limits. In case of a separate section, it should be negotiated with other projects in order to avoid an unexpected loss.
