The civil engineering of Jinan ventilation pipes and components should be carried out according to the conditions of exposed and concealed installation of air pipes. For the air pipes installed on the surface or in the technical interlayer, the civil construction of the ventilation pipe installation or the main works and the ground assessment and painting shall be completed in the future. If the civil construction and other operations are carried out after the ventilation pipe installation, the ventilation pipe may be damaged, especially the air cleaning system, which will cause pollution in the pipe.

對暗裝風管的裝置，應及時合作土建施工，不然將會損壞土建的裝修吊頂、墻面。

For the installation of concealed air duct, the civil construction shall be cooperated in time, otherwise the decoration ceiling and wall of civil engineering will be damaged.

在施工過程中，應依據土建的進展安排，派專人密切合作土建，做好孔洞的預留和預埋件的敷設作業，以免裝置時再打洞，既糟蹋工料又影響土建工程質量。

In the construction process, according to the progress of civil engineering, special personnel shall be assigned to cooperate closely with civil engineering, and the hole reservation and laying of embedded parts shall be done well, so as to avoid the re drilling of devices, which will not only waste the materials but also affect the quality of Civil Engineering.

節裝置前的準備作業一、裝置前的準備作業風管體系裝置前，應進一步核實風管及送回(排)風口等部件的軸線和標高是否與規劃圖紙相符，并查看土建預留的孔洞、預埋件的方位是否符合要求，依據施工計劃斷定的施工辦法安排勞動力出場，并將預制加工的支、吊、托架、風管按安排好的施工次序運至現場。

Section I preparation before the installation I. preparation before the installation of the air duct system before the installation, it is necessary to further verify whether the axis and elevation of the air duct and return (exhaust) air vent and other components are consistent with the planning drawings, check whether the positions of the holes and embedded parts reserved in the civil engineering meet the requirements, arrange the labor force to leave the site according to the construction method determined in the construction plan, and support the prefabrication and processing , crane, bracket and air duct shall be transported to the site according to the arranged construction sequence.

同時，將施工輔佐用料(螺栓、螺母、墊料及粘接劑、密封膠等)和必要的裝置東西準備好，依據工程量巨細及體系的多少分段進行裝置。

At the same time, the construction auxiliary materials (bolt, nut, gasket, adhesive, sealant, etc.) and necessary devices shall be prepared, and the devices shall be carried out according to the size of the project and the number of sections of the system.
