First of all, the installation of ventilation pipes, first of all, notice that in fact it is also in the ventilation pipe assembly, in a relatively short period of time in the pipeline, to a large extent, it can also be a ground assembly, followed by pipelines for a long period of time, to a large extent, in fact, it can also be directly assembled in the ground unit according to the status of the installation site.

　　风管装配时，风管的和水平应尽可能调整，在很大程度上可以直接避免风管的变形或上下波动和左右摆动。此外，应该注意的是，每个部分的风道不应超过10m。装配时应将垫片压平，法兰螺栓拧紧均匀，使螺母帽面朝同一方向。

　　When the duct is assembled, the center and level of the duct should be adjusted as far as possible. To a large extent, the deformation or fluctuation of the duct can be avoided directly. In addition, it should be noted that each part of the duct should not exceed 10m. When assembling, gaskets should be flattened, flange bolts should be tightened evenly, so that the nut face faces in the same direction.

　　此外,通风管道,管道之前到位,很大程度上其实也应该注意对水的直接检查所有支架与海拔度,然后,注意应该是直接检查的程度强烈的腿,管的地方也可以采用直接和传播者,这两个方法。

　　In addition, ventilation pipes, pipes in place before, to a large extent, should also pay attention to the direct inspection of water support and altitude, and then, pay attention to the degree of direct inspection should be strong legs, pipes can also use direct and disseminator, these two methods.

　　那么，对于通风管道截面相对较小，且其位置相对较低，在很大程度上，其实可以直接采用人工就位的方法，只需要直接设置简单的脚手架也可以。

　　Then, for the ventilation duct section is relatively small, and its location is relatively low, to a large extent, in fact, the method of manual positioning can be used directly, as long as a simple scaffold can be directly set up.

　　后告诉大家，通风管道上的风管截面在其管道截面上较大较长，其实就是在其很大程度上可以直接采用滑轮、倒角链或大绳等方法。为了方便在通风管道上安装风管，应注意风管应直接悬挂在脚手架上。

　　Finally, let us know that the cross section of the air duct in the ventilation duct is larger and longer than that in the duct section. In fact, to a large extent, pulleys, chains or ropes can be directly used. In order to facilitate the installation of air ducts on ventilation pipes, it should be noted that air ducts should be directly suspended on scaffolding.
