通風(fēng)管道的安裝施工是非常重要的工作，不僅要配合工程中的其他工種，自身的布局設(shè)計(jì)還很有難度的。那么，通風(fēng)管道是如何施工的呢？
The installation and construction of ventilation duct is a very important work. It is not only necessary to cooperate with other types of work in the project, but also difficult to design its own layout. So, how is the ventilation duct constructed?
1）對(duì)于比較復(fù)雜的民用建筑，在設(shè)計(jì)階段，各工種（暖通、給水排水，供電照明與建筑）首先應(yīng)協(xié)商好空間分隔，定出每種管道的標(biāo)高范圍。一般情況下不得越出給自己規(guī)定的界限，遇有個(gè)別管段要越界時(shí)應(yīng)與其他工程協(xié)商。
1) For complex civil buildings, at the design stage, various types of work (HVAC, water supply and drainage, power supply and lighting and Architecture) should first negotiate the space separation and determine the elevation range of each kind of pipeline. Generally, it is not allowed to cross the specified boundary. In case of crossing the boundary of an individual pipeline section, it shall negotiate with other projects.
2）解決各種通風(fēng)管道相碰及協(xié)調(diào)的原則，一般為：“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)改變冷、熱水管道。
2) The principle to solve the collision and coordination of various ventilation pipes is generally as follows: "the small pipe gives way to the large pipe, and the pressure gives way to the non pressure". For example, if the water pipe collides with the air duct, the water pipe should turn. If the cold and hot water pipes collide with the downpipe, the cold and hot water pipes shall be changed.
3）施工前應(yīng)設(shè)備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種通風(fēng)管道用一種彩色筆，在各交點(diǎn)處綜合其標(biāo)高，看是否有矛盾之處，及時(shí)發(fā)現(xiàn)，將問題解決在安裝之前。
3) Before construction, the engineer of the equipment main pipe shall draw the pipeline and single line of each type of work on a plan. A color pen shall be used for each ventilation duct to synthesize its elevation at each intersection to see if there is any contradiction, find it in time and solve the problem before installation.
4）為了減少投資，節(jié)省空間，降低層高，有些敷設(shè)無坡度要求的通風(fēng)管道，可以穿梁敷設(shè)（如自來水管道，消防噴灑干管等）。
4) In order to reduce investment, save space and reduce floor height, some ventilation pipes without slope requirements can be laid through beams (such as water pipes, fire sprinkler mains, etc.).
