(1)风管组装:当风管较短时,可一次在地面组装而成,当风管较长时,可视安装场地的情况,在地面分段组装。组装时应尽量调整风道的中心度和水平度,避免风管扭曲或上下起波,左右摆龙,每段风道不宜超过10m.组装时,垫片应垫平,法兰螺栓应均匀拧紧,螺母帽均朝向同一方向。
(1) Air duct assembly: when the air duct is short, it can be assembled on the ground at one time. When the air duct is long, it can be assembled in sections on the ground according to the situation of the installation site. When assembling, the center and level of the air duct should be adjusted as far as possible to avoid the twist of the air duct or wave up and down. The left and right swing dragon should not exceed 10 m. When assembling, the gasket should be flattened, the flange bolts should be tightened evenly, and the nuts should be in the same direction.

(2)风管就位:风管就位前应检查全部支架的水乎度和标高、检查支架的牢固程度,风管就位可采用直接和吊具两种方法。对风管断面较小,又位置较低的可采用人工就位方法,只需搭设简易脚手架即可。当风管断面较大且管段较长时,可采用滑轮、倒链、大绳等方法吊装。为了便于风道就位,一般多采用将风道吊在脚手架上,然后再将其抬放在风道支架上的方法。脚手架应沿其风道长度方向搭设,高度和位置应适合施工操作,吊装顺序应先干管后支、立管,吊起时,吊点应牢固,两吊点应均匀受力。垂直风管可采用人工和大绳辅助就位。调整风管保证垂直度要求。
(2) Air duct in place: Before the air duct in place, the water degree and elevation of all the supports should be checked, and the firmness of the supports should be checked. For the air duct with small cross-section and low position, the manual positioning method can be adopted, and only simple scaffolding can be erected. When the section of the duct is large and the pipe length is longer, pulley, inverted chain and large rope can be used for hoisting. In order to facilitate the location of the air duct, the general method is to hang the air duct on the scaffolding, and then put it on the air duct support. Scaffolding should be laid along the length of its air duct direction, height and position should be suitable for construction operation, hoisting sequence should be trunk pipe after support, standpipe, hoisting, hanging point should be solid, two hanging points should be uniform force. Vertical wind pipes can be manually and rope assisted. Adjust the air pipe to ensure the perpendicularity requirement.
(3)风道调直:就位在支架上的风道,应拨正位置,调整风道横平竖直,然后再按图集要求固定。
(3) duct straightening: the duct positioned on the bracket should be straightened, the duct should be adjusted horizontal and vertical, and then fixed according to the requirements of the atlas.
