因而要搞好把握多用途消音管的工艺特点，了解施工图纸，掌握土建工程和其他技术工种同本工种的有关状况，核查风管系统软件的设计标高，中心线、预埋孔眼，埋件等能否合乎安装标准。备齐安装用的各种辅材，准备好吊装机具和安装用的其他专用工具，对风管系统软件画线定位等工作中。

Therefore, it is necessary to grasp the process characteristics of multi-purpose silencing pipes, understand construction drawings, grasp the relevant conditions of civil engineering and other technical trades with this profession, and verify whether the design elevation, centerline, embedded holes, embedded parts, etc. of the air duct system software meet the installation standards. Prepare various auxiliary materials for installation, prepare lifting equipment and other special tools for installation, and perform line drawing and positioning work on the air duct system software.

起吊前，要对风管支、支架，吊装机具，采用吊装机具的支、起吊点，是不是恰当、坚固开展查验，吊装前应认真仔细，把杆、滚轮、绳锁等是不是固定不动，捆扎靠谱并要起吊范畴内的多种不稳定要素。吊装时，要开展试吊，当距地200－300Mm时，终止起吊，再一次对吊装机具开展一次查验，确定没有问题后，再次起吊到所需相对高度。把风管固定不动在支、支架上以后，才可以解除绳锁，拆移吊装机具。

Before lifting, it is necessary to inspect whether the support and lifting points of the air duct support, bracket, and lifting equipment are appropriate and sturdy. Before lifting, it is necessary to carefully check whether the rod, roller, rope lock, etc. are fixed and fixed, and the binding is reliable. Multiple unstable elements within the lifting scope should be eliminated. When lifting, a trial lifting should be carried out. When the distance from the ground is 200-300Mm, the lifting should be terminated, and the lifting equipment should be inspected again. After confirming that there are no problems, the lifting should be lifted again to the required relative height. Only after fixing the air duct on the support and bracket can the rope lock be released and the lifting equipment be removed.

风管的组对：将制成品或预制构件好的风管运到安装地址，联系实际情形开展查验、核查，再按序号开展排序，风管系统软件的各部位外形尺寸和视角确确准确无误后，即逐渐风管组对工作中。风管各管段中间的联接选用法兰联接，连接处规定严实不透风。一次起吊风管的长度要依据房屋建筑的标准，风管的厚度，起吊方式和吊装机具配置状况明确，组对好的风管可把两边的法兰作为标准，以正中间法兰为测量点，吊线测量风管的联接是不是竖直，误差大时要开展调节

Assembly of air ducts: Transport the finished or prefabricated air ducts to the installation location, conduct inspection and verification based on the actual situation, and then sort them by serial number. After the external dimensions and perspectives of each part of the air duct system software are confirmed to be accurate, gradually assemble the air ducts. The connection between each section of the air duct adopts flange connection, and the connection is strictly regulated to be airtight. The length of the air duct to be lifted at once should be based on the standards of the building, the thickness of the air duct, the lifting method, and the configuration of the lifting equipment. The assembled air duct can use the flanges on both sides as the standard, with the middle flange as the measurement point. The suspension line should measure whether the connection of the air duct is vertical, and adjustment should be carried out when there is a large error
