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。遇有个别管段要越界时应与其他工程协商。

1) for complex civil buildings, at the design stage, all kinds of work (HVAC, water supply and drainage, power supply lighting and Architecture) should first negotiate the space separation and determine the elevation range of each pipeline. The general case not set himself beyond the boundaries. In case there is a separate section to cross the boundary, we should negotiate with other projects.

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, the water pipe and the wind pipe collide, then the tap 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) before the construction, the engineer of the equipment general pipe will draw the lines of each type of work and draw the single line on a flat map. Each type of pipe is used with a color pen. In each point of the intersection of its elevation, see if there is any contradiction, timely discovery, the problem is solved 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 pipes without slope requirements can be laid on beams (such as water pipes, fire sprinkler pipes, etc.).
