故而要干好找准二妙用消声管的工序特征 ，学习进行施工cad图，掌握了房建工程建筑和许多工艺技术工种分类同本技术工种分类的有关于问题，稽核管道体系免费软文的设计方案标高，中心点线、预埋件孔眼，埋件等是不是完全符合连接规范标准。备好连接用的一些辅材费，备好好公司机具和连接用的许多使用平台，对管道体系免费软文画线确定等本职工作能力。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.安放前，要对通的管道道支、统一好架，设备起重卸载机具，利用设备起重卸载机具的支、安放点，就是还没有当、坚实深入推进检测，设备起重卸载前应该严肃认真非常仔细，把杆、滚珠、绳锁等就是还没有统一好动不起来，捆带靠普并要清理安放基本概念内的多重不稳定可靠原则。设备起重卸载时，要深入推进试吊，当距地200－300Mm时，终结安放，再多次对设备起重卸载机具深入推进多次检测，来确定还没有一些问题后，又一次安放到需求对于非常。把通的管道道统一好动不起来在支、统一好墙上后来，才行解除限制绳锁，拆移设备起重卸载机具。
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.管道的组对：将结合品或装配式零件好的管道运回组装详细地址，搞好关系具体情况环境抓好核对、审核，再按序号抓好排名，管道电脑软件系统电脑软件的各个部位位外型尺寸和角度确确最准确没有问题后，即会逐渐管道组对岗位中。管道各管道期间的相连起来选则活套活套法兰片相连起来，相连处规程严实不通风透气。一起起重设备吊装管道的尺寸要遵循原则房屋搭建搭建的标准化的，管道的尺寸，起重设备吊装具体方法和设备吊装机具运行环境状态制定，组对好的管道可把边上的活套活套法兰片最为标准化的，以正期间活套活套法兰片为測量点，吊线測量管道的相连起来是没有是竖向，确定误差大时要抓好调理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
