通风管道的施工要遵循什么原则

发布人:http://www.qyyl789.com   发布时间:2017-09-14 16:39:55

通风管道主要应用在工业及建筑工程中,应用领域主要涉及:电子工业无尘厂房净化系统,医药食品无菌车间净化系统,酒店宾馆、商场医院、工厂及写字楼的中央空调系统,工业污染控制用除尘、排烟、吸油等排风管、工业环境或岗位舒适用送风管、煤矿抽放瓦斯用抽放瓦斯系统、煤矿矿井环境控制用送回风系统等等;

The ventilation pipe is mainly used in industrial and construction projects, mainly related to application: purification system of electronic industry clean workshop, purifying system of medicine and food aseptic workshop, hotels, hospitals, shopping malls and office buildings factory of central air-conditioning system, with the addition of dust, smoke and fume exhaust pipe, etc. industrial environment comfortable by feeding or post the wind pipe, coal mine gas drainage in coal mine gas drainage system, environmental control system, industrial pollution control air supply;

1)对于比较复杂的民用建筑,在设计阶段,各工种(暖通、给水排水,供电照明与建筑专业)首先应协商好空间分隔,定出每种管道的标高范围。一般情况下不得越出给自己规定的界限。遇个别管段要越界时应与通风管道其他工程协商。

1) for more complex civil buildings, in the design phase, the various types of work (HVAC, water supply, drainage, power supply lighting and building professional) should first negotiate space separation, determine the elevation of each pipe range. The general case not set himself beyond the boundaries. In case of crossing the section, consult the other works of the ventilation pipe.

2)解决各种通风管道相碰及协调的原则,一般为:“小管让大管,有压让无压”。例如,自来水管与风管相撞,则应当自来水管拐弯。冷、热水管与下水管相碰,则应改变冷、热水管道。

2) to solve all kinds of ventilation pipe collision and coordination principle, generally: "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 together, should change the cold and hot water pipe.

3)施工前应设备总管的工程师,将各工种的管线,单线画在一张平面图上。每种管道用一种彩色笔。在各交点处综合其标高,看是否有矛盾之处,及时发现,将问题解决在安装之前。

3) the engineer of the equipment main shall, before construction, draw the lines of each type of work on a single plan。 Each pipe uses a color pen。 At the intersection of each of its elevation, to see if there are inconsistencies, timely discovery, the problem before the installation。

4)为了减少投资,节省空间,降低层高,有些敷设无坡度要求的管道,可以穿梁敷设(如自来水管道,消防喷洒干管等)。

4) in order to reduce investment, save space and reduce storey height, some laying pipelines without slope requirements can be laid through beams (such as water pipes, fire fighting, dry pipes, etc。)。
