濟(jì)南通風(fēng)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(chǔ)設(shè)施。通風(fēng)管，風(fēng)管制作與安裝所用板材、型材以及其他主要成品材料，應(yīng)符合設(shè)計(jì)及相關(guān)產(chǎn)品現(xiàn)行標(biāo)準(zhǔn)的規(guī)定，并應(yīng)用出廠檢驗(yàn)合格證明，材料進(jìn)場時(shí)應(yīng)按現(xiàn)行有關(guān)標(biāo)準(zhǔn)進(jìn)行驗(yàn)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(fēng)管道相碰及諧和的準(zhǔn)繩，普通為：“小管讓大管，有壓讓無壓”。例如，自來水管與風(fēng)管相撞，則應(yīng)當(dāng)自來水管拐彎。冷、熱水管與下水管相碰，則應(yīng)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(fēng)管道是專門為一處或幾處房間或設(shè)備送風(fēng)和排風(fēng)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(fēng)管要保證表面光滑潔凈，室外風(fēng)管應(yīng)有防雨、防雪措施。 風(fēng)管伸入結(jié)構(gòu)風(fēng)道時(shí)，其末端應(yīng)安裝上鋼板網(wǎng)，防止系統(tǒng)運(yùn)行時(shí)，雜物進(jìn)入金 屬風(fēng)管內(nèi)。

　　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(fēng)管與結(jié)構(gòu)風(fēng)道縫隙應(yīng)封堵嚴(yán)密。 風(fēng)管穿越沉降縫時(shí)應(yīng)按設(shè)計(jì)要求加設(shè)套管，套管與風(fēng)管的間隙用填料(軟質(zhì))封 堵嚴(yán)密，從這些特點(diǎn)我們應(yīng)該可以很快的區(qū)分開兩者的區(qū)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
