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.

对暗装风管的装置，应及时合作土建施工，不然将会损坏土建的装修吊顶、墙面。

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.

在施工过程中，应依据土建的进展安排，派专人密切合作土建，做好孔洞的预留和预埋件的敷设作业，以免装置时再打洞，既糟蹋工料又影响土建工程质量。

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.

节装置前的准备作业一、装置前的准备作业风管体系装置前，应进一步核实风管及送回(排)风口等部件的轴线和标高是否与规划图纸相符，并查看土建预留的孔洞、预埋件的方位是否符合要求，依据施工计划断定的施工办法安排劳动力出场，并将预制加工的支、吊、托架、风管按安排好的施工次序运现场。

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.

同时，将施工辅佐用料(螺栓、螺母、垫料及粘接剂、密封胶等)和必要的装置东西准备好，依据工程量巨细及体系的多少分段进行装置。

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.
