濟南通風管道工程是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。通風管，風管制作與安裝所用板材、型材以及其他主要成品材料，應符合設計及相關產品現行標準的規定，并應用出廠檢驗合格證明，材料進場時應按現行有關標準進行驗收。

　　A ventilation duct is a municipal infrastructure designed to circulate air and reduce the concentration of harmful gases. Ventilation pipe, air pipe fabrication and installation for plates, profiles and other major product materials, design and related products shall meet the requirements of current national standards, and the application of the factory inspection certificates, materials should be carried out according to the relevant current national standard of acceptance.

　　2、處理各種通風管道相碰及諧和的準繩，普通為：“小管讓大管，有壓讓無壓”。例如，自來水管與風管相撞，則應當自來水管拐彎。冷、熱水管與下水管相碰，則應改動冷、熱水管道。

　　2, processing and coordination of various ventilation pipeline collision criterion, common: "let the pressure get tubular bassoon, no pressure". For example, when the water pipe is in collision with the air pipe, the water pipe should be turned. The cold and hot water pipes and water pipes should collide, change the cold and hot water pipeline

　　通風管道是專門為一處或幾處房間或設備送風和排風的管道。排煙管道是專門共排煙氣的管道，就用處來講有分別，就管道本身講都是管道。

　　A duct is a duct that supplies air or air for one or several rooms or equipment. Smoke exhaust pipe is a special flue gas pipeline, in terms of use, there are differences, the pipeline itself is the pipe.

　　安裝完的風管要保證表面光滑潔凈，室外風管應有防雨、防雪措施。 風管伸入結構風道時，其末端應安裝上鋼板網，防止系統運行時，雜物進入金 屬風管內。

　　Installation of the wind pipe to ensure that the surface smooth and clean, outdoor air pipe should be rainproof, snow prevention measures. When the air duct is extended into the air duct of the structure, the steel plate net shall be installed at the end of the air duct to prevent the sundries from entering the metal air pipe when the system is running.

　　金屬風管與結構風道縫隙應封堵嚴密。 風管穿越沉降縫時應按設計要求加設套管，套管與風管的間隙用填料(軟質)封 堵嚴密，從這些特點我們應該可以很快的區分開兩者的區別

　　The gap between the metal duct and the structural duct should be tightly sealed. When the wind pipe passes through the settlement joint, the casing shall be added according to the design requirements, and the gap between the sleeve and the air duct shall be sealed tightly with filler (soft), and from these characteristics we shall be able to distinguish the two areas very quickly
