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.
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.
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.
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.
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.
