通風(fēng)管道加固能夠保證通風(fēng)管道在實際應(yīng)用中內(nèi)部靜壓的穩(wěn)定性，如果管壁道出現(xiàn)1%的撓度，則需要對通風(fēng)管道展開加固處理。在實際通風(fēng)管道加固的過程中，需要根據(jù)壓力大小、尺寸大小選擇相應(yīng)的加固方式，加固方式的選擇，對更終通風(fēng)管道的使用壽命起到?jīng)Q定性作用，通常情況下，可以使用以下幾種方式展開加固。
The reinforcement of ventilation duct can ensure the stability of internal static pressure in practical application. If the deflection of pipe wall is 1%, it is necessary to reinforce the ventilation duct. In the process of actual ventilation pipeline reinforcement, it is necessary to select the corresponding reinforcement method according to the pressure and size. The selection of reinforcement method plays a decisive role in the final service life of the ventilation pipeline. In general, the following methods can be used for reinforcement.

一、拉桿加固
1、 Tie rod reinforcement
在此過程中需要使用鋼彩、套管等材料展開加固，需要在500pa以下對其展開正壓加固。
In this process, steel color, casing and other materials need to be used for reinforcement, and the positive pressure reinforcement should be carried out under 500pa.
二、框架加固法
2、 Frame reinforcement method
該種加固方式可以使用輕鋼龍骨展開加固。
In this way, light steel keel can be used for expansion and reinforcement.
三、抱合加固法
3、 The method of locking reinforcement
其中使用的材料也是輕鋼龍骨，通常應(yīng)用在較為特殊的管道加固中，其中主要包括在900彎管道、三通管以及悶頭管等。
The material used is light steel keel, which is usually used in special pipeline reinforcement, including 900 bend pipe, tee pipe and bulkhead pipe.
由此可以看出，在通風(fēng)管道加固施工的過程中，需要根據(jù)管道的位置、實際使用情況等方面內(nèi)容展開加固。除此之外，還可以采用防下垂加固法，這種方式主要對特殊管道展開加固，其中主要包括迂回管道以及變經(jīng)管道等，避免通風(fēng)管道在實際應(yīng)用過程中出現(xiàn)位移以及下垂等情況。
It can be seen that in the process of ventilation pipeline reinforcement construction, the reinforcement should be carried out according to the location of the pipeline and the actual use. In addition to this kind of reinforcement method, it can also be used to prevent the pipeline from sagging.
