　　The installation of ventilation pipes and components should be carried out in accordance with the conditions of installation of ventilation pipes and dark installation, and it is necessary to have certain conditions. Surface installation or skill installation of pipeline in sandwich should be partly installed in ventilation pipeline engineering and construction, or be examined and painted. In the future, civil engineering technicians and other operations of Shandong ventilation pipeline may damage ventilation duct, air purification system, especially the pipeline pollution if the ventilation duct is installed. For installation of dark pipes, civil construction should be coordinated in time, otherwise the ceiling and wall of civil decoration will be damaged.

　　在施工過程中,特殊人員應該分配給密切合作與土木工程根據土木工程的時間表,以保證預埋件預留孔和鋪設,以避免材料的浪費,對土木工程的質量的影響。上班前一季度的安裝和安裝之前管道系統安裝前準備工作,應進一步驗證管和回(行)風口軸線和標高、等符合設計圖紙,并查看公民預留洞、預埋件的方向符合需求,根據施工計劃決定安排勞動力,和預制分支,懸掛,支架,風管按照施工順序安排運到現場。

　　During the construction process, special personnel should be allocated to cooperate closely with civil engineering according to the schedule of civil engineering, in order to ensure the pre-embedded parts reserved holes and laying, in order to avoid waste of materials and the impact on the quality of civil engineering. Before the installation and installation of the pipeline system in the first quarter of work, the preparatory work before installation should further verify that the axis and elevation of the pipe and return (line) tuyere meet the design drawings, and check the direction of the reserved holes and embedded parts for citizens to meet the requirements. According to the construction plan, the labor force, prefabricated branches, suspensions, brackets and ducts should be arranged according to the construction plan. Sequence arrangement for delivery to site.

　　同時，施工輔助材料(螺栓、螺母、墊片和粘合劑、密封劑等)和必要的安裝材料也都準備好了，根據工作量和系統的多少節進行安裝。

　　At the same time, construction auxiliary materials (bolts, nuts, gaskets and adhesives, sealants, etc.) and necessary installation materials are also prepared, according to the workload and the number of sections of the system for installation.

　　可安裝風管首先需要的東西有:扳手、鋼絲鉗、螺絲刀、鋼鋸、錘子、扁鑿、沖頭、錘子、鋼帶、水平儀、滑輪、麻繩等。

　　The first things needed to install the air duct are wrenches, wire pliers, screwdrivers, steel saws, hammers, flat chisels, punches, hammers, steel belts, levelers, pulleys, hemp ropes, etc.
