第一：施工前应设备总管的工程师要求，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。

First: before the construction, the engineer of the equipment main pipe should be asked to draw the pipeline and single line of each kind of work on a plan. Each type of pipe is used with a color pen. At all points of intersection, we should synthesize its elevation to see if there are any contradictions, and find them in time, and solve the problems before installation.

观察现场的施工情况，因为现场施工情况不一样的话，连接的长度也是不一样的，所以我们先要将螺旋风管一节一节的放在支架上衔接起来，这是最开始的步骤。

To observe the construction situation of the site, because the site construction is not the same, the length of the connection is different, so we first have to put a section of the spiral pipe on the bracket to connect, which is the first step.

第二：当小管遇到大管时，有压让无压锌螺旋风管，就好像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。

Second: when a small pipe meets a large pipe, there is a pressure free zinc spiral air pipe, which is like a water pipe colliding with the wind pipe. When cold and hot water pipes collide with the water pipes, the cold and hot water pipes should be changed.

第三：为了减少投资扁圆螺旋风管，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。

Third: in order to reduce investment in flat spiral air pipes, save space and reduce storey height, some laying pipes without slope requirements can be laid through beams.
